Warm-Up in Store

There’s no question about it: the biggest upcoming weather story is the big warm-up that’s in store not just for Winnipeg & the Red River Valley, but much of North America. After one more cold night tonight, temperatures will move towards seasonal values by the end of the week and then push towards above-normal by the end of the weekend. Given that November just finished up as the 22nd coldest on record that was some 4°C below normal[1], news of a prolonged warmer trend is likely very welcome news for many.

Wednesday
-15°C / -20°C
Mainly sunny; becoming partly cloudy in the evening

Thursday
-8°C / -15°C
Mix of sun and cloud

Friday
-9°C / -15°C
Mix of sun and cloud

Medium-range model consensus is showing high agreement in an above-normal temperature trend through the first half of December.

Today will be a relatively cool day courtesy a cold front that passed through Southern Manitoba overnight. Daytime highs will sit near -15°C through the Red River Valley today under mainly sunny skies and relatively light west to northwesterly winds. A ridge of high pressure moving through the region tonight will help temperatures dip to a chilly -20°C overnight.

Southerly winds will develop through the Red River Valley in advance of an approaching warm front quickly advancing across the Prairies. The winds – climbing to only around 20-30km/h – will help our overnight low as relatively “mild” as it is as well as begin ushering in warmer air. Temperatures will climb to around -8°C by Thursday afternoon as the winds gradually diminish under mixed skies. Temperatures will dip to the -15°C on Thursday night.

Looking to the end of the week, Friday appears to be a near-copy of Thursday with light winds, mixed skies and a high of -9 or -8°C and a low once again near -15°C.

Seasonal to slightly above seasonal temperatures will continue through the weekend alongside a slight chance for some light snow.
