This week will start out cold and fairly benign. Our next chance for snow will come midweek.
After another cold morning on Monday, temperatures will warm up a bit during the day. Highs on Monday afternoon should be in the low to mid minus teens, a significant improvement from Sunday’s minus twenties, but still chilly. The wind will be a bit breezy from the south on Monday, but wind chills values won’t be significantly colder than the air temperature (except in open areas). A weak low pressure system will pass through Southern Manitoba on Monday night, bringing some cloud cover along with it. As a result, temperatures on Monday night will be warmer than those on Monday morning as the cloud prevents heat from escaping from the surface. Unfortunately, temperatures won’t increase much on Tuesday, as we only see temperatures rise a few degrees from the morning lows. Our next little warm-up will begin Tuesday night as an approaching low develops a southerly flow over Southern Manitoba allowing temperatures to rise overnight.
As the low moves into (or just south of) Manitoba on Wednesday, it will bring our next chance for snow. At this point models suggest we may see as much as 5 to 10cm from this system, or perhaps as little as 2cm. Additionally, there are indications that we may see another weak system pass by on Thursday, bringing another small bought of snow. At this point it is too early to say how much snow to expect from these systems, but 5 to 10cm in total for both looks like a good initial “guess”. More information about the potential for snow will be available as the week progresses.
