Significant winter Storm Coming To Southern Manitoba

Hey everyone , back for a blog update and I unfortunately have some upsetting news. Southern Manitoba and we’ll basically all of our forecast region is basically under the gun for significant snowfall all thanks to a low pressure system moving into our region. The interesting part about this system is that it will have a sharp deformation zone (cut off line for heavy snowfall.) This system will mark the transition into a much cooler temperature trend but not before we get a decent winter storm . Find out more in this weeks weather update from Mike McGregor. 

Today (Above): Southern Manitoba get ready to rock and snow dance??? Anyways my horrible take on words again. As I  write this at 130PM the west part of southern Manitoba is now in the crosshairs of the low pressure system. This band of snow that has already moved into areas just north of highway 1 up to the parklands will gradually move east and southeast. There is some concern that this initial band may be strong enough to cause whiteout conditions and poor visibility for those travelling on the highways. Blizzard conditions are basically expected across an area from the Manitoba border to the interlakes, portage la prairie, east to Winnipeg and Grand beach areas. Highway1 and south may be impacted slightly by this storm but not until later in the day. Total snowfall accumulations by this evening will vary from between 5cm in Winnipeg to as much as 10-12cm just west of Brandon in a narrow swath. Temperatures this afternoon will sit in the low minus single digits for most, with areas along the American border sitting in the low single digits. 

Tonight: Oh boy this is when the weather will really get interesting, mother nature will likely be throwing a rave (in simple terms that means significant snowfall will be impacting a large zone of our forecast area.) I don’t really like saying the S word but regardless we have to talk about it. By about 5pm the heaviest snowfall will be covering areas from just along and north of highway 1. By about 8pm the heaviest of snowfall rates will be impacting areas along a swath from the Manitoba border east to Winnipeg and Grand Beach north to central Manitoba. Much of the south will be impacted by blowing snow and poor visibility tonight. If you are travelling consider taking it easy. Areas of the south among the American border up to about Highway two can expect to be at risk for freezing rain with ice pellets for a majority of the night. Part of the reason is this region will be in the warm sector of the low pressure system or near the warm front Generally areas from just south of Virden East to Glenboro than south towards pilot mound east to Winkler, and then Steinbach. Total snowfall accumulation for G the overnight timeframe are expected to be between 12 to 15cm for Brandon east to Winnipeg there could be snowfall amounts more than 15cm in localities overnight. Temperatures tonight will sit quite mild with overnight lows in the mid minus single digits. 

Friday (Above): Heavy snow will persist in the morning hours on Friday. There will be a weakening trend towards the latter half of the morning and early afternoon. There will still be periods of snow over the region, but expect much less accumulations on Friday then on Thursday night. There will still be areas with heavy bands of snow but only about 10-12cm is possible around Brandon accumulated in 12 hrs by 18Z, the rest of the day between 2 to 3cm is likely. Temperatures will be mild mainly in the mid minus single digits. -1 to -5C. For a broad swath of the south. 

Friday Night: A brief, but heavy burst of snowfall can be expected during the overnight timeframe as the remainder of the system moves through this band whoever will just be a brief but heavy cluster of snow, which will likely put our total accumulations up a little bit more significant snowfall, however, will not be likely for our region during Friday and Friday night. Another 1-5 cm is possible for a broad area of the south. I will have a summary of total snowfall just in this paragraph below. Temperatures on Friday night will be in the minus teens in Southwest Manitoba anywhere between -10 and -12° with windchill corresponding colder towards the -20°C range. Areas in the south east however will be spared this cold with temperatures and the minus upper single digits, with windchill values in the minus teens. 

Areas across the Manitoba see anywhere between 5 to 45 cm of snow. The highest accumulations are forecast once again in the riding mountain national Park area. Then as you go south and east and slightly north for areas just to the east Brandon to Winnipeg upwards of 20 to 30 cm of snow. Then south of this band as well up to Central Manitoba 5 to 15 cm of snow as possible. 

In regards to ice accumulations: Expect anywhere between one to 3 mm of ice buildup. There will also be a mixture of snow within the freezing rain along the American border. Power outages are possible especially within all areas of this winter storm event. 

Saturday and Sunday/Long Range: Much, weather conditions will be present over the weekend with temperatures a little bit cooler. The good news is that our overnight. Low temperatures will not drop into the minus teens, however windchill values may be in the minus teens for this weekend with overnight lows in the upper minus single digits. Our daytime highs in the lower minus single digits as the sun gets higher in the horizon. Snow will begin melting hopefully. 

The good news is this during the latter half of the week warmer Pacific air will begin filtering in across the Prairie provinces, it may take a couple of days for us to get there, but we will begin seeing high temperatures in the upper single digits between 3 to 6°C I strongly believe as the sun begins getting higher in the horizon. We will be start starting to see temperatures closer to 10° at some point as our normal value temperatures go up.

Major Colorado Low Set To Impact Southern Manitoba

 Get ready southern Manitoba another round of significant winter weather is on the way and this is one of those storm systems that we've been keeping in our eye on for the last couple of days. This Colorado low low pressure system is likely going to be impacting our region within the next 24 to 48 hours various weather impacts will be included including freezing rain, snow, blowing snow as well as a slight risk of thunderstorms in extreme southeastern Manitoba. We will have full information in this weather blog updates, the important thing to keep in mind is that the low pressure system could change location within the next while which may change precipitation impacts. 

The rest of the night in southern Manitoba will be generally cloudy with some. Of clearing this will be very sparse though unfortunately if you're looking for a clearing spot for the upcoming lunar eclipse tonight is definitely not gonna be that fortunate for Eclipse viewing. Tonight's temperatures will remain well within our seasonal range of the minus one to minus seven degrees Celsius range.

Tomorrow (Friday) the Colorado pressure system will begin to move into southern Manitoba ahead of it very warm mild air for this time of year will filter into the southeastern parts of the province temperatures during the afternoon will rise into the lower single digits with areas of southwestern Manitoba just only being able to nudge up to the zero to minus 1 or - 2 degree mark. So the weather pattern does look like there will be a possibility of some increasing chances for showers in southeastern Manitoba during the afternoon because there will be maker or very low levels of instability there is a very slight chance that some of these showers could produce some thunder. My concern goes towards the latter half of the day when lights to moderate snowfall will begin in southwestern Manitoba as we move a little bit further to the east. The low pressure system will be bringing in freezing rain mixed with ice pellets more than likely this will be in the form of freezing rain given the fact that this region will be in the transition part between above zero temperatures and below zero temperatures. I haven't been able to look at the temperature profile in the upper levels however models have been consistent at bringing in moderate freezing rain over the Red River valley during the late afternoon into the evening. Yesterday the NA MNES T model was suggesting upwards of 12 to thirty millimeters of freezing rain, Most of the weather models have been struggling to capture the moisture content of this low pressure system. The more recent run of the models is suggesting that the region of Winnipeg including Elie East to the Ontario border could be dealing with heavy snow mixed with freezing rain by the evening. Environment Canada has forecast rain in Winnipeg with a high of plus 3C. Southwestern Manitoba is at a higher potential risk for the development of snow and blowing snow highway travel will be difficult during the daytime and I will have a snowfall forecast map below these summaries, despite not much in the way of snowfall accumulations. 

Friday Night: During the mid to late evening hours areas of southeastern Manitoba will begin to start seeing snow mixed with freezing rain then transition over to heavy snowfall before tapering off towards the early morning hours the good thing about that slow pressure system is that it will be fast moving. Regardless when the temperatures drop below zero during the latter half of the evening lot of this rain will begin to freeze on contact if it hasn't already with either rain or freezing rain both will freeze with temperatures going down below zero. My main concern is a possible increased risk of power outages as well as traffic accidents and given the fact that road conditions will be quite poor during this time frame any highway travel is not suggested and Justin has also mentioned that with the snow coming in conditions will become difficult to drive in. 

Models are also showing the potential for thunderstorms mixed in with the freezing rain  in southern Manitoba tomorrow night as the freezing rain moves into the region before the snow begins after midnight. 

Temperatures on Friday night will likely drop while into the minus single digits some areas of southwestern Manitoba may see value is more typical of February with anywhere between minus ten to minus fifteen degrees Celsius. Wind chill also has to be factored in as well with these temperatures as winds will become out of the northwest.

Information on total precipitation amounts;

Red River Valley and southeastern Manitoba Freezing rain threat: Total amount anywhere between 5 to 10 millimeters with as low as one to two millimeters of ice accumulation. Snowfall will become heavy overnight into the morning with another 10 to 20cm of snow possible in a narrow band as the system moves east.

Southwesterm Manitoba: Despite there being snow and blowing snow accumulations will be well below any reasonable amounts only 2-3 centimeter accumulation is possible in some areas.

Information for the Weekends Weather: Saturday and Sunday look to be a lot calmer, high pressure will begin moving in from the West bringing in a much more stable air mass however temperatures will be cooler than they have been the good news is that this air is modified which is going to basically make things a bit better for us. Daytime high temperatures on the Saturday will be in the minus single digits between minus 1 to minus 8 degrees Celsius overnight into Sunday temperatures in the low it to mid minus teens are possible with the coldest air in Western Manitoba in higher elevations by the Duck Mountains and Asseippi Provincial Forest. Southern Manitoba will then have temperatures below normal on Sunday night with overnight low values in the minus teens and upper minus single digits. 

Warmer Weather Is Here, Deep Freeze is Done. Rain Possible on the weekend.

 Good evening everybody I have a weather update for all of you and this is one that I have not done in a month so I'm just catching up on all the current weather forecast trends and it looks like much of our region is going to be taking a reprieve from the significant cold that we have experienced over the last For two to four weeks. This forecast is going to be quite simple and uncomplicated. Justin has already had some of it covered but I also have my own view of this upcoming pattern. I'll try and make it fun. 

Tonight: For all of you at night owls who are still up our temperatures tonight are gonna be weirdly rising, and I say normally this time of year our temperatures drop as we go through the overnight however because we now are on the east side of an area of high pressure winds are coming out of the South and allowing for a southerly flow to develop over a region. It'll bring in a warmer air mass as we approach the morning hours our temperatures will rise into the mid minus single digits now that's something I can handle however please don't be complaining that we're still in the minuses at this point we've been worse back in 2013 we were locked in extensive cold well into the month of April. 

Saturday: Saturday should be a gorgeous afternoon with temperatures rising into the minus single digits, There is also a good possibility of some increasing cloudiness towards the late afternoon hours in the southwest, however during the afternoon and early evening I expect some spots of sun to persist with a mix of sun and cloud mainly in the southeast. During the night on Saturday a low pressure system will be approaching from the West in southeastern Saskatchewan ahead of it very warm air will be moving into our region which will keep our temperatures within the minus single digits during the overnight time frame there will be some warming areas in the southwest which may see values closer to the minus 1 or - 2 marked by the morning hours. Is some inconsistencies on the current setup for the precipitation which is expected during the day on Sunday if anyone in the southwest during Saturday night sees precipitation it will likely fall as snow.

Sunday: This is when the weather gets mighty interesting on the day Sunday much of southern Manitoba will be basking in a unusually warm air mass and our temperatures will rise into the low to mid plus single digits we will be in the warm sector of a low pressure system. During the early afternoon a area of rain will develop and mostly move across the West Bend and Brandon Regions moving into southeastern Manitoba towards the late afternoon and early evening. The latest H Triple R Model Run is suggesting that areas of central West Manitoba will be seeing some heavy snow there will be a brief. For freezing rain and also this freezing rain threat will persist pardon me present itself over the Red River Valley as well depending on where the freezing levels set up during the afternoon.

Sunday night: Much of the region will continue seeing temperatures within above seasonal values and this is actually welcoming considering how cold it has been our overnight low temperatures will be sitting in the low minus single digits and right around zero degrees for a majority of the region. Any precipitation during Sunday evening will move out of the region by shortly after 9:00 PM I'm expecting that there is a risk for some ice accumulation of any rain that builds up as a result of the freezing rain or rain that falls with temperatures dropping below zero overnight there is a risk of either highway closures or increased risk for road safety problems.

It looks like this warm weather will persist into the beginning of the week, I do see a couple of more Clipper systems moving in on Monday and Tuesday in Saskatchewan they may impact our region at some point within the week it's too far ahead to tell at this point if you are looking for the warmth and maybe even get out there and put on some shorts with considering how warm it will likely be this weekend just don't go and tell others that it was us that said that you could do that.

Clipper System To Usher In Warmer Weather Over Southern Manitoba

 Hey everyone, I have an update for all of you on our upcoming clipper system. It’s likely to impact our region tonight and tomorrow as well as aHey everyone, I have an update for all of you on our upcoming clipper system. It’s likely to impact our region tonight and tomorrow bringing in warmer conditions for the weekend, as well as a update on our weekend weather conditions there’ll be a brief and very non-technical weather blog for all of you if you’re wanting to keep up-to-date, you can follow the Weather Center, Manitoba as well. Let’s get into the details.

Tonight: A clipper system will be on the prowl and will enter our region by this evening into the overnight timeframe with impacts being felt in the Assessippi provincial park regions by the 9pm-10pm timeframe this snow will traverse south and east through the evening with areas from Melita to lake Manitoba and up to Hecla being affected by this system during the overnight timeframe west to the Manitoba and Saskatchewan border. Temperatures tonight will warm from the low minus teens to the mid minus single digits by morning for areas that see snow clear out, warmer further west cooler east. So a low of minus 12C for Winnipeg and -6C for Brandon. 

Friday:Most of the snow will likely move through the red river valley by the late morning and early afternoon hours. With Temperatures rising into the high minus single digits by afternoon with most of the region experiencing snow and flurries as the area of low pressure system stalls over the area. Snow and flurries including blowing snow will end during the early evening hours.

****BE ADVISED Highway Travel isnt suggested during the heavy snowfall and winds will also drive near blizzard conditions at times as well. If you have to travel then I would suggest taking your time and increase your following distance and if there is warnings issued we do not recommend highway travel. However be safe out there when you are on the roads. 

Friday night: Much of southern Manitoba will be in the influence of a incoming cold front which will drop our temperatures into the mid minus teens and there is a possibility as a result of this system driving south that wind chill values may reach the minus twenties again with scattered flurries persisting overnight. Temperatures during the overnight timeframe will drop into the minus teens. 

The Weekend: Much calmer weather conditions will persist through the rest of the week and with temperatures likely sitting well into the minus single digits with overnight lows the exception on Saturday night in the minus teens before moderating temperatures on Sunday in the minus single digits with temperatures in the minus single digits likely for overnight lows on Sunday Night. 

Warmer weather is likely ahead into the next week with Pacific flow resulting in this weather pattern. 

Happy New Year, Significant Winds Likely with Blizzard Conditions this weekend. Cooler weather arriving next week.

 Everyone welcome back to a new year in the weather scene hello everyone mike mcgregor here returning for the first post of 2025 and we've got some really concerning weather news on the horizon for southern sections in Manitoba looks like we're in for a bumpy 24 to 48 hours so fastening your seatbelts and get ready for an action packed blog with information on a blizzard which is poised to impact our region and I'll have comprehensive details on the upcoming major cold that is expected to impact our region this weekend into next week. I know it's winter folks but we'll get through this together again i'm got some interesting news about this weather blog and where it's headed at the end of this post.

Tonight: Southern sections of Manitoba will be in the warm sector of a low pressure system which will be impacting us tomorrow afternoon, Temperatures tonight will be warming for some sections with areas of southern Manitoba from southwest parts of the province into the Red River Valley and some sections of the Manitoba escarpments seeing warming temps by morning between minus three to zero degrees.

Tomorrow: Tomorrow morning specifically speaking Friday morning significant blizzard conditions will develop over the Red River valley including Winnipeg with forecast winds from 60 to 80 kilometers an hour with gusts possibly up to A100, there looks like there will be some light to moderate snowfall during the hours of 8:00 AM to 12:00 PM and then this time frame visibility will be drastically reduced or near impossible for those within warned regions for blizzard conditions. I have already spoke to Justin and there is no doubt in my mind that highway travel including city travel will be hazardous so do not be surprised if they have school bus cancellations within and outside of city limits in rural areas. The winds will be out of the N which will be ushering in a significantly colder air mass as we head into our weekend. The good thing is that these strong winds will likely abate by be late afternoon to early evening hours given the fact that the snowpack within the city limits is not fresh and in fact melted and frozen there may be less problems with visibility and more problems with loose objects or items getting tossed in the wind. Make sure to tie down loose items if possible. Temperatures in the afternoon will drop into the mid to upper minus teens with wind chills in the minus 20s and upper minus teens. Friday night: Calmer weather conditions will come in place as high pressure moves in however because this Arctic air mass will be settling in overnight lows will be in the minus 20s with the possibility of wind chills in the minus 30s frostbite is possible with exposed skin.

The Weekend: Calm weather conditions will persist into the weekend with temperatures over our region unfortunately reaching the mid to upper minus 20s with wind chill values in the mid to upper minus 30s areas that are in central Manitoba especially near dauphin up to the interleakes may see wind chills in the minus forties. This weather pattern will persist and Sunday night will be the coldest with windchill values in the minus 40's for much of our region. 

Next Week: I have some unfortunate news folks if you're looking for the milder weather conditions that we have been experiencing that's not gonna happen there is a higher likelihood that during the first half of the week into the middle part of the week where we will see our temperatures remain in the mid minus 20s in some areas maybe fortunate enough to see temperatures in the mid minus teens however wind chill values will be persistently stuck in the minus 30s and minus 40s this coming week during the overnight time frame that is when the colder temperatures will occur. There is a change in the pattern by Wednesday when we may be seeing some milder Pacific air filtering into our province just be glad we're not stuck in a full-on strong La Nina if we were we would be consistently experiencing these very cold temperatures.

Happy Holidays, warmth persists and above normal temperatures persisting.

 Hey everyone Mike McGregor here I hope you all are having a blessed and relaxing holiday season I am looking forwards to the new year I have a brief update on the extremely warmer than average temperatures we’re seeing , we are seeing temperature anomalies in the teens to twenty degrees above average . By the way . I’ll be back in the new year with a more extensive weather update based on latest model data we might be in for an interesting new year with a potential winter storm in the mean time I’ll be covering what’s ahead for the rest of the Christmas holidays . Much of southern parts of Manitoba will be experiencing above average temperatures and and overall a strong southerly flow will be present with a ridge of high pressure in eastern Canada allowing for this warmer than average temperature trend. 

(Above:) CFSV2 Temperature anomalies showing above average temperatures persisting over the next 7 days . 

Thursday: Temperatures on the day Thursday will be in the low minus single digits, areas of southeastern Manitoba will be the warmest with high values sitting in the zero to minus one degree range. Areas of southwestern Manitoba will be sitting in the mid minus single digits. Mostly cloudy skies are likely.

Thursday Night: Temperatures are also expected to remain warm for the night and I’m surprised to say this that areas of southeastern Manitoba will remain warm with values in the low minus single digits around zero however areas of the southwest will be likely be more in the lower minus teens. 

Friday: A warm and mostly cloudy day is likely on the day, there will be a disturbance moving through during the afternoon and evening with a chance of rain and freezing rain in areas of south central Manitoba. Small accumulations are likely with only 1 to 2mm. Temperatures on Friday are expected to soar into the low single digits in the southeast with areas of the southwest near the freezing mark. 

Friday Night: We will still be enveloped by this warm airmass, rain or snow is likely in the southeast part of Manitoba during the overnight. After that a slightly cooler airmass moves in with overnight lows in the minus single digits the chance of temperatures in the region of -4 to -7C is likely.

Saturday and Sunday: Warm weather conditions will persist with calmer and much sunnier conditions, although a little cooler overall we will still be be above average. Temperatures for this period will be in the low minus single digits, for day time highs and mid to high minus single digits near and below -10C during the overnights. 

For reference (low minus single digits are (-1 to -5C). 

Mid minus single digits are -5C to -10C, and the minus teens is -10 to -20C. 

Have a merry Christmas!!! 

Winter Storm Set To Impact Southern Manitoba during the day on Sunday

 Hey everyone it's Mike here writing a brief update on a significant winter storm that is likely to impact will be impacting southern Manitoba this weekend I'm a bit late to the party as I'm just getting over a really bad cold it's going around apparently some other people I know have it. What what I've got from other people over the last six to 12 hours is that there is some pretty hefty amounts of snowfall forecast over southern Manitoba this weekend and this system will be moving into the southern sections of the province by the early morning hours so if you're looking for details this is your place for that. If you're interested I also have something to say about this on the weather comedy report however I had no idea that we were gonna be getting a winter storm models showing next to nothing for Southern Manitoba over this weekend and now we're about to get something really interesting. 

Sunday: An area of low pressure will be moving into southern sections of the province during the morning hours ahead of the main stationary occluded front a large area of snow mixed with freezing rain will likely be impacting areas from the Saskatchewan Manitoba border all the way to the Portage La Prairie and Winkler regions. The heaviest snowfall starting at 6:00 AM in Western Manitoba and then 10am in the Red River valley areas. The thing is the heavy snow will likely be persisting in areas of Western Manitoba during the afternoon before tapering during the late afternoon whereas areas in the Red River valley will likely see snow persist well into the evening and possibly overnight time frame into Monday. I have some concerns that heavier snowfall bands visibility will be reduced to well below zero visibility if you have travel plans please consider leaving during the morning hours and not during the afternoon, also highways may likely be also closed. this system is gonna be feeding off some moisture from the Pacific as a Pacific flow will likely transition into a polar northerly flow behind this as cold air wraps in behind it.

The good thing about this is that I do not have to write nearly as long of a write-up the previous storm system we had had multiple types of precipitation however I'm going to get to the snowfall totals right now. Areas in western Manitoba will bear the brunt of the system with a general 10 to 20 centimeters of snow possible of the areas in the Red River valley and points south including the Interlakes all the way to the American border can expect a general 10 to 15 centimeters or so with possibility of areas receiving more than fifteen centimeters by the end of tomorrow night. The snow will be a heavy wet snow during the afternoon hours and Justin had mentioned that it will be a dryer snowfall during the overnight time frame into Monday regardless this is the first accumulating significant snowfall for areas of the eastern half of Manitoba. I have attached some photos below of the forecast snowfall and the forecast storm.

Temperatures for tonight's Will drop into the low minus single digits tomorrow afternoon a majority of Southern Manitoba will be basking in mild temperatures between minus one and minus 2 degrees Celsius for most. Areas along the American border however will likely see temperatures a degree or two above freezing or around the zero degree mark.

The Week Ahead:. Temperatures will be on a declining mark with the majority of southern sections in Manitoba likely seeing temperatures dipping into the minus single digits to the low minus teens towards the beginning and middle of next week.
