Warm Week Continues, Cold or Snow For The Weekend! Information provided by A Weather Moment

It will continue to be a warm week this week as mild air from the pacific continues filtering in, before we arrive in another coldsnap to start the weekend into next week. Highs getting 3 to 6C above average before the coldsnap arrives. As tough as the weather may sound it will not be a long coldsnap at all.

For the night ahead expect clear skies as a cold front slumps southwards with winds blowing from the north. Overnight lows expected at and slightly below minus ten for most people in the south.

Thursday will be a bit cooler with a weak ridge of high pressure moving in behind the cold front that passed through on Wednesday night, high temperatures around and slightly below minus five expected through the day on Thursday. A high of minus six can be expected in Winnipeg on
Thursday. There is a chance of flurries during the day but expect that to clear out by the evening timeframe for the region.

Friday will be the warmest day of the week as temperatures soar with the Jetstream sitting off to the North

Friday will be the warmest day of the week as an area of low pressure enters the central Manitoba region bumping our high temperatures as light westerly winds take hold. High temperatures expected around the freezing mark in the southeastern half of the province including the red river valley, but getting slightly above freezing for the Westman and Dauphin regions up towards the Swan River and Saskatchewan border. A cold front will slump southwards during the evenin bringing a chance for flurries and snowfall, winds will shift to the north around 30km/h. Temperatures will unfortunately dip down to near the minus ten mark overnight.

Long Range: Potentially Cold and Unsettled

Looking ahead in the long range various models have differing ideas on the way a low pressure system may track. Temperatures may stay cool and the weather may be clear if the system stays south, or it may possibly travel through the area, bringing with it seasonable temperatures and some snow. It all depends on how the system travels. At this moment though based on what I'm seeing from the NAM model (the most accurate short range model) it looks like the system will travel through our area and give us snowfall. That would favour warm temperatures for us but I will keep you all updated on this on Twitter.



Warmth returns March 2nd, 850MB Temps show that on this ECMWF model run.

Potentially Above Seasonal For The Start Of The Week

Looking ahead to next week if we see a cooldown and the system does not go through our area our temperatures will quickly switch from below seasonal to near and above average based on the latest ECWF run. It also agrees on Brett Anderson's weather outlook with mild to above average temperatures. Keep in mind our average daytime high is about -6C so if we see above average temperatures we will probably be around zero to even above zero at times. Our weather may end up being variable though if this ridge that is out west doesn't move east, and we remain in a northwestern flow providing periods of warmth and cold with numerous low pressure systems sliding through. I do agree more on a above seasonal temperature trend though. Spring is definitely on the way!

Week Of Warm Weather Brings Weekend Coldsnap

 

Manitoba will enter a phase of warmer weather this week before we end up in another arctic airmass to start the weekend.
 

 

 

 

The warm weather and south winds we saw today was in part due to a trough of low pressure that is hovering over our area. Tonight an area of snow will develop as the trough of low pressure moves through, switching our winds to the north by the morning Tuesday.

 

For the day Tuesday "winds will be out of the North at 20 to 30km/h with a few flurries persisting during the day along with cloudy skies" according to Scott from A Weather Moment. Despite having winds out of the north the temperatures will remain mild around the mid minus single digits for most.

 

Wednesday will also be cloudy and mild with clearing conditions later on in the day, highs closer to zero at around -5C to -2C. It will still be a decent day but those who hate grey days it will be one of those. Pacific Air will dominate for the remainder of the week here, while southern ontario deals with a major snowstorm and strong winds out of the north. They are expecting up to 30cm in some areas they can have it, I feel bad for them as winter will stick around longer because of the increased snow cover.

 

 Long Range

 

                                                              Cold Blast to end the Week

                                                   850mb temperature anomaly Feb 29

                                                  850mb Temperature Anomaly Mar 1st

                                                  850MB Temperature Anomaly Mar 2nd

 

 

After a week of warmer than normal temperatures we will likely be greeted by another blast of arctic air to start the weekend and by the looks of the ECMWF weather model it may end around the 1st of March to the 3rd of March. Theweathernetwork also latches onto this idea. So it will be very brief as to previous years we would be stuck in it for weeks, thank you El Nino!

Spring Pattern Setting Up

After a period of very warm weather that melted all of our snow last weekend in through the week , the snow came back with a vengence giving southern Manitoba another taste of Winter  despite there being rainfa

ll with the system. During the day on Tuesday through Wednesday, the seasons first most potent storm system came through Southern areas giving regions impressive snowfall totals some areas racking up as much as 25cm. This appears to be the last significant snowfall of the season here in Manitoba, let's hope. (Totals shown below).

The snowfall and gusts of 60-70 km/h making visibilities low and highways very slippery, it was quite bad for motorists who were travelling along highway 75, 59 and Highway 1, 6, 16 and 10. 2 Accidents ocurred, one about 5km east of Elie with 2 semi trailers that collided in a jackknife collison. Also along highway 75 a schoolbus rollover occured by Ste Agathe. There were also several other rollovers that occurred which resulted in highway closures. http://winnipeg.ctvnews.ca/treacherous-road-conditions-lead-to-multiple-manitoba-crashes-1.2296304 

There were also power outages in parts of Winnipeg, on Inkster and out in the Dugald areas. Southern Manitoba for the most part had numerous power outages caused by heavy snow and wind (which caused power poles to ignite). Manitoba Hydro is working on a fix for towns affected. On top of the snow that we recieved we also picked up about 8mm of rain here in the Winnipeg area. So what will our weather look like for the next few days? Let's have a look below.

Thursday: 

The day on thursday will be a fairly cool day with the wind blowing from the Northwest fairly light, although given the strong March sun it may not feel all that bad outside. There probably will be a significant amount of melting given the below zero temperatures that are forecast for the day so it will probably feel nice outside. We cool down a couple degrees past the minus ten mark, overnight. May not all be that bad. 

Mix of Sun and Cloud

-3C / -13C

Friday:

Friday will be a sunny day to start off in the red river valley, until a system slides through our region as flurries move out of southwestern Manitoba. Amounts of 1 to 2cm can be expected in the Winnipeg area. There will be a likely chance they will exit the region by around mid afternoon, any snow that falls will likely melt. High's will still be about 2 or 3 degrees below average in the Winnipeg area.                                                                                                     

Flurries then Sunny

-2C/-12

Saturday Through Monday

Is it is looking like another storm system will be on our doorstep for the day on Saturday and Sunday. It is still quite far out to say anything yet, although given our model trends with past storm events it's quite likely this will turn out to be a event worth talking about.

However latest model runs are showing that it will be warm enough to support a rain event. That will likely be the case considering we are nearing the month of April, the rainy month. So it may be a cloudy and wet weekend with temperatures sitting above zero for the most part. It has been a dissapointment that our weather has not been dry and mild, however as we get further into Spring our weather will certainly get nicer. So with the look of things we are starting to enter a more typical stormy spring pattern, and hopes are that the weather will get a lot better and not stay  gloomy and wet althrough the spring. We aren't in Vancouver after all. :-)
