Slightly Milder and Slightly Below Temperatures Return, Possible Colorado Low

 As you know already much of the region has experienced well below average temperatures off and on since the beginning of February, this relentless cold snap has finally removed its grip on southern Manitoba as pacific air has started to influence parts of the prairies and the polar vortex moved on east, therefore moderating our temperatures. The weather pattern could also become more active over the coming days as low pressure systems ride along the westerly to northwest jetstream. This outlook will cover Tonight-Thursday. 

(Above: Tuesday looks to be the warmest day of the week, temperatures will sit in the mid to high minus single digits. Colder weather for the rest of the week. Data is from WeatherBell Analytics Pro). 

Tonight: A low pressure system will sit off to the west , ahead of it cloudy to partly cloudy skies are likely tonight with a chance of flurries exists for the southwestern half of Manitoba, with light snow likely in the extreme southwestern portions. Temperatures tonight will drop into the mid to high minus teens (-12 to -18C) windchills however might be even colder with values in the mid minus teens to the low -20’s. The coldest of the values will probably be felt by the areas around Lake Winnipeg and into the northern red river valley. 

Tuesday: Will be met with some of the nicest weather yet this week, sunny to partly cloudy skies are expected during the afternoon with the exception being the latter half of the day when thicker clouds build in. Temperatures will soar into the mid to high minus single digits mainly with values between (-4C and -7C), it may feel a lot colder with the wind factored in so windchills will sit in the high minus single digits for areas along and south of the Trans Canada highway, areas along and north of the trans Canada will be likely seeing WC’s in the low minus teens (-10 to -12C). Tuesday Night: A large area and swath of snow will move through on Tuesday night although light in nature, about 2-4cm can be expected in some places a general 5cm can be expected if heavier bands fall. Temperatures on Wednesday night will sit in the low to mid minus teens (-10 to -15C), and windchills in the upper minus teens along and south of the trans Canada highways (-15 to -19C) Windchills will sit in the low to mid minus twenties for the parklands and the interlakes (-20 to -26C). 

Wednesday and Thursday: Both Days will be dominated by warm weather conditions or closer to seasonal, on Wednesday cloudy skies are likely during the day with high temperatures in the low minus teens (-10 to -14C) and windchill values in the high minus teens and the low minus 20’s (-16C to -22C). Wednesday Night cold arctic air will filter in again as clearing skies allow for a temperature drop. Temperatures will swing down into the mid to high minus 20’s (-24C to -28C) with most of the windchills dropping past minus 30C hovering in the low to mid minus 30’s (-30 to -36C). 

Thursday will be a slightly warmer day our highs will sit in the high minus single digits to the low minus teens (-7C to -12C), the windchill values will sit in the mid to high minus teens (-12C to -18C). The warmer areas will likely be in spots of the parklands during the daytime. Thursday Night an approaching low pressure system will likely bring in a batch of colder air as the system sits to our south and this system will form by Colorado, which is going to be something to watch. Clear to partly cloudy skies will result for the night, temperatures will sit in the mid to high minus teens in areas of the interlakes and the eastern half of Manitoba (-15C to -18C) areas elsewhere will see lows in the low to mid minus 20’s (-20 to -25C). Windchills unfortunately won’t care and will sit in the low to high minus 20’s and the low minus 30’s (-20C to -31C) especially in the SW. 

Second half of the week details come on Thursday or Friday with more info on the Colorado low that could impact us. Signs are that it will miss us to the south but we will have to watch future model trends for any updates. Too early to say when or what impacts we will get .
