Snow is getting underway in the Red River Valley from the next Clipper. Winds will also increase this afternoon, creating poor travel conditions. Many highways in western Manitoba are already closed. Use caution if heading out - conditions will worsen quickly.

On tomorrow's noon surface forecast map you can see the next Clipper approaching from Saskatchewan. Meanwhile today's Clipper is still trucking along through central Quebec. (data from the @weatherlogics.bsky.social WRF).

Today's @weatherlogics.bsky.social 4-km WRF simulation over western Canada suggests that blizzard conditions are likely to redevelop tomorrow in southern Manitoba. Snow will move from west to east during the day, along with southerly winds of 40-60 km/h gusting to 60-80 km/h.

While tomorrow's Alberta Clipper technically isn't as strong as today's, it may still pack a punch. Strong southerly winds are expected in the Red River Valley in the afternoon, along with more snow, so near blizzard conditions are possible again!

The worst of the Alberta Clipper is now over, but conditions will remain poor today as blowing snow continues. Winds will gradually ease, calming right down tonight as high pressure builds in. High pressure won't last long - the next Clipper arrives tomorrow!

A significant Alberta Clipper is still on track to impact the Prairies starting tomorrow. For southern Manitoba, the worst will be Wednesday night-Thursday morning. Travel conditions will be very dangerous and highway closures are likely. Here is our latest snowfall forecast.

Canada now has a colour-coded alerting system. My early thoughts: 1) Emphasizing colours (yellow-orange-red) is good because severity is more obvious than calling things watches-warnings-advisories. 2) The main issue I see is how these are going to be issued.

The growing season finally came to an end last night in urban Winnipeg. The Forks recorded a low temperature of -1.1 C, the first frost since April 30. This capped a remarkable 175 day-long growing season.

There was a hard freeze in southern Saskatchewan this morning. Mankota, SK got all the way down to -10 C! Frost also occurred in Western Manitoba, with the lowest temperatures near the Saskatchewan border. Frost is likely again tonight in Westman - it will be patchy farther east.

I spotted some unusual mammatus clouds overhead this afternoon. They’re unusual because normally mammatus are associated with strong thunderstorms. In this case there are just some rain showers in the area. #mbwx

Watching an area of thunderstorms that are developing over southeastern MB. These storms are being triggered semi-parallel to a stationary front over northern Minnesota. Should they continue to expand tonight, locally heavy rain is possible at they move slowly northeast. #mbstorm

This will be the last week of summer-like weather in southern Manitoba, with temperatures running about 10°C above normal. Conditions are expected to return to normal next week with highs sinking back into the mid teens. #mbwx
