Medium-range weather models have again done a darned good job getting the big picture right. We saw a large low track across the north late last week into this week, bringing strong southerly winds along with very warm temperatures to all of Manitoba Friday and Saturday. As advertised, a cold front pushed through Sunday, bringing with it a few quick showers and a return to more seasonable temperatures.
The large area of low pressure forecast to develop in the central U.S. this week didn’t materialize, thanks partly to a strong area of high pressure building in from the west. This will bring sunny to partly cloudy skies for all of this week along with highs in the mid-teens to maybe 20 C if we get enough sunshine. The overall forecast for this period is surprisingly similar to last week’s.

Predicting Manitoba winter snowfall
How much snow should farmers in Manitoba expect for the rest of December 2025 and into January-February 2026? Here’s what the weather models say about the winter to come.
Late in the week, the weather models again show an area of low pressure developing to our northwest, then tracking across the border between the Prairies and the Territories. This low will be smaller, weaker and moving quicker than the previous low. Our winds will become southerly ahead of the low on Friday, but we’ll only see a modest boost in temperatures, with highs maybe making it into the low 20s. This low will drag a cold front through southern and central regions Saturday, which will bring some clouds along with a few scattered showers. As with last weekend’s cold front, skies should quickly clear out as high pressure again builds in from the west.
This high will bring sunny skies Sunday and Monday along with daytime highs in the mid-teens. An area of low pressure is then forecast to develop to our southwest on Tuesday and bring clouds and showers into our region by late Wednesday. There’s a chance of significant rainfall with this system before it’s pushed out by high pressure late Thursday. This system bears watching, but confidence levels are fairly low.
Usual temperature range for this period: Highs, +8 to +19 C; lows, -3 to +6 C.
