Cooler Weather Settling In

After a windy day yesterday, Southern Manitoba will see cooler weather through the remainder of the week as a fairly seasonal air mass sits anchored over the region. While cool, things will remain dry as any showery weather remains locked up in Central Manitoba & the Northern Interlake.

The Next Few Days


16°C / 3°C
Some cloudy periods.

16°C / 3°C
Partly cloudy.

10°C / 2°C
Increasing cloud, cooler.

Today and tomorrow will be essentially carbon copies of each other. Highs will sit around 16°C with overnight lows near 3°C. Winds are expected to be fairly light both today and tomorrow. Both days will have some cloud around; today we’ll see some cloud pushing up from North Dakota through the Red River Valley while tomorrow we’ll see some cloud slumping southwards from the Interlake. While there may be some light shower activity with the cloud pushing southwards from the Interlake, at this point the entirety of it is expected to remain west of the Red River Valley in the Riding Mountain region slumping southwards into SW Manitoba.

Things will cool off a bit on Friday in the Red River Valley as an intensifying low pressure system in South Dakota/Minnesota draws cooler air from the north into the Red River Valley through the day. Any rain this system produces will remain south of the Canada/U.S. border in the Dakotas and Minnesota. We’ll see some cloud push into the Red River Valley through the day thanks to this system. Exactly who will see cloud and who won’t will be tough to call; the cloud will likely have quite a sharp edge thanks to a strong deformation zone. It will be fairly safe to say that places such as Steinbach and areas SE will end up overcast by day’s end while areas west of Winnipeg, such as Portage la Prairie, will likely remain fairly sunny. Here in Winnipeg we’ll likely sit somewhere near the edge of the edge of the cloud by day’s end.

Looking to the Weekend

The weekend looks fairly quiet over much of Southern Manitoba. Benign weather will dominate over SW Manitoba, things should remain fairly calm over the Red River Valley and the SE portion of the province will see a shot of getting some rain.

An area of rain looks to push northwards out of North Dakota and Northern Minnesota as a developing low lifts NE out of Minnesota on Friday night. The area of rain will have a very sharp edge on it’s northwestern flank thanks to the aforementioned strong deformation zone. Most models are keeping all of the rain in the United States, however some higher-resolution long-range and medium-range models are starting to creep the system a little further west and introduce some rain activity into SE Manitoba on Saturday, likely through the Sprague region. At this point, I’d say that the region has just a slight chance of some rain.

The Red River Valley looks to remain completely clear of the rain for this system with mostly clear skies and cool-to-seasonal temperatures.
