A brief reprieve from adverse winter weather is expected today in southern Manitoba before another "MacKenzie Screamer" arrives tomorrow. Additional light snow is expected and strong winds will again produce significant blowing snow. Poor travel conditions should be expected.

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.

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!

This storm officially met blizzard criteria in Winnipeg as visibility at the airport remained below 400 m (0.25 miles) for at least 4 consecutive hours (criteria met for 6 hours total). Note: The definition of a blizzard is now different from that of a blizzard warning.

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.

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

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.

Training thunderstorms produced heavy rainfall exceeding 100 mm (4 inches) in southern Manitoba overnight. Training storms are analogous to a freight train, as storms repeatedly pass over the same location. But why did this happen?
