Winter wallop coming to southern Manitoba, cooler temperatures to follow.

 Once again southern Manitoba is set to be impacted by another Colorado system which will impact parts of the region From tonight into Thursday evening and early Friday, the details of this system are finally becoming clearer with a definite possibility of southwestern parts of Manitoba experiencing the brunt of the system with areas of the SE and S central part of the province seeing rain mixed with snow with very little snowfall accumulations. This will put an end to our mild temperature pattern that we've been experiencing however if you're looking for some hope there is longer days on the horizon as we near spring.

(Above: Southern manitoba is looking to be impacted by a strong low pressure system, with snow and rain eneveloping a large portion of Manitoba).

This evening: a A low pressure system will begin to move into South Central and southwestern parts of Manitoba areas of the southwest can expect to see a swath of heavy snow with snow and blowing snow. Areas of the southwest will be the hardest hit during the overnight. With a majority of the snow falling from a southwest to NE line from SW Manitoba to Dauphin including Brandon, Neepawa, Russell, Riding Mountain, and the Interlake portions of the province up to Ashern and Hecla the rain snow line will set up just to the West of Winnipeg where below freezing temperatures will be situated to the west of the Red River valley which will allow that areas of the southeast part of the province will get mostly rain during the overnight. A general five to ten millimeters of rain can be expected in southeastern parts of Manitoba including the Red River Valley into the morning hours. By the morning hours of General 5 to 10cm of snow is probable in the Western half of Manitoba into the interlakes. Overnight low temperatures tonight will remain below From areas west of Portageville Prairie including all of Western Manitoba and Lake Manitoba, so values between minus 2 to minus 5 degrees celsius is possible overnight. Areas of southeastern and south central Manitoba however will be remain above zero for night lobes with values between 1 and 3 degrees Celsius the further east you go it will be warmer

Thursday in regards to the heavy snowfall there is a possibility that some parts of Southwest Manitoba into the interleaves could possibly receive 10 to 25 centimeters of snow in small pockets models are not really agreeing on full amounts however there may be pockets of heavier precipitation that fall specifically in the Interlake regions. The NAM model is suggesting a broad swath of 15 to 25 centimeters of snow whereas other models are suggesting five to fifteen centimeters and heavier localized snowfall amounts of twenty to twenty five centimeters of snow. This will be the complete total snowfall amounts not a additional 25 centimetres of snow that has already fallen so you guys are wanting to see the full amounts of expected precipitation including rain and snow have a look at the weather graphic that I have attached above this post . There’s a possibility of seeing pockets of heavier than 5cm accumulation in the pembina valley into the red river valley. Snowfall warnings are in place for western Manitoba with amounts of 10 to 15cm or more. Eastern Manitoba special weather statements are in place for a rain and snow mix. On Thursday rain will begin to transition into snow in parts of southeastern Manitoba shortly after the lunch hour as cold air begins to wrap around the backside of the system, this will reduce the overall amounts of snow in the southeast with only about five centimeters of snow expected where areas to the west of Winnipeg may receive upwards of ten centimeters. The system is very tricky so forecasting total snowfall amounts is nearly impossible fora given radius or coordinates so if you guys need to know about the forecast for your area check out weather.gc.ca for information on the upcoming winter storm. Thursday high temperatures in the east will be still in the upper side of freezing with over all high temperatures in the lower single digits around zero to 4 degrees Celsius. Areas of the west will see high temperatures in the mid to low minus single digits. 

Thursday night the backside of the pressure system will begin to move into all parts of the province as a result we will be on the east side or the West side of the low pressure system, this will end up resulting in strong northwest or northeast winds depending on where you are in the province snow and blowing snow Only in areas of southeastern Manitoba can expect to be under the presence of snow and blowing snow this will be a possibility with reduced visibility. Snowfall accumulations for the SE part of Manitoba will be meager compared to areas of the southwest part of the province, models are divided on the total snowfall amounts however a general consensus at the moment shows about 3 to 5+ centimeters of snow for areas of southeast part of the province given the fact that majority of the moisture will be dropped on the west side of the province. Overnight low temperatures on Thursday night in south central parts of Manitoba just west of Winnipeg will drop into the lower side of the minus single digit value is some areas may also see low minus teens between minus 9 to minus 14 degrees Celsius areas outside of that in the southwest and southeast ports of the province will likely see values in the upper minus single digits from minus 6 to - 9 degrees Celsius.

Friday should be a much calmer day as low pressure system departs into northwest ern Ontario this is good news as the system will not stay for longer than a day and a half, remnant the flurries are possible over parts of South Central and southeastern Manitoba. If anyone is looking for sunshine Friday is the day for that western parts in Manitoba will be under a stable air mass, Western Manitoba should be basking in Sun however parts of the South including the Red River valley and eastern Manitoba may be experiencing the opposite with periods of sun and cloud. North winds are likely on Friday With temperatures over the day on Friday reaching the upper minus single digits in the Interleakes and areas south of that in the mid minus single digits.

The weekend: It appears likely that Manitoba will finally experience the much calmer weather pattern will be on the west side of high pressure so we will experience a northerly flow as a result it will be much cooler than compared to previous couple of weeks. High temperatures on the weekend will be in the mid to high minus Single digits areas of the interlake parts of the province however will be in the low minus teens for the day on Saturday and Sunday. A more typical February like pattern will be setting up over the weekends which will likely persist since the week, high temperature values in the mid to high minus single digits for daytime highs and for overnight lows in the low to mid minus teens with windshield values in the upper minus teens.
