Note preliminary: It appears Manitoba has set a new 24-hr provincial rain record with the storms on Tuesday night. I've confirmed a high-quality gauge measurement of 292 mm (11.48 in) approx. 2 km west of Stonewall. #mbstorm

If anyone north of Winnipeg (including Stonewall) has rain gauge measurements I would really appreciate you sharing them (including location when possible). This was potentially a record event for Manitoba, so I'd like to document it as much as possible. #mbstorm

More thunderstorms are beginning to develop this afternoon in the Red River Valley and southeast. Severe storms are possible again - not expecting a repeat of yesterday, but hail, damaging winds, and heavy rain are possible again. #mbstorm

For all the flack the RRFS has been catching, it was the only model to consistently show supercells affecting the RRV yesterday. Indeed, many runs specifically showed a supercell right over Winnipeg. It has certainly performed no worse than any other CAMs over the past 3-4 days.

If anybody saw hail today I would greatly appreciate any reports. Specifically the location, time, and size.

Stonewall, MB has received 208 mm (~8 in) of rain today including 190 mm in the past 4 hours. Beware of flash flooding potential in the area! #mbstorm

Please also be alert to flash flooding potential tonight. Many areas have received torrential rain. Road washouts are possible and water is often deeper than it appears! Just north of Winnipeg (e.g. Stonewall) has already received 150 mm+ (6 in +) and counting. #mbstorm

Storms have exited Winnipeg for now, but more are on the way. A strong line of storms is presently located from Portage la Prairie southward to just west of Morden. This line will impact the Red River Valley over the next few hours. #mbstorm

An incredibly strong push of moisture is about to enter southern Manitoba from ND/MN. As this moisture arrives the potential for severe weather will begin. (See dewpoints in green of 20-23 C just south of the border). #mbstorm

Widespread severe weather, including the risk of tornadoes, is expected today in southeastern Saskatchewan and southern Manitoba. Storms may also produce torrential rain, very large hail, and destructive winds. #mbstorm #skstorm

Today is the most dangerous severe weather setup I have seen in southern Manitoba in a long time. Storms could produce tornadoes, destructive winds, and very large hail. If thunderstorms approach, take shelter immediately. #mbstorm

Severe weather will redevelop again today across eastern Saskatchewan and southern Manitoba. Dangerous storms are possible, with a risk of large hail, damaging winds, heavy rain, and tornadoes. Here is our severe weather outlook. #mbstorm #skstorm

There is a risk of severe thunderstorms tomorrow in eastern Saskatchewan and western Manitoba. These storms could produce large hail, damaging winds, heavy rain, and tornadoes. The risk of severe weather is expected to continue on Sunday in southern Manitoba. #mbstorm #skstorm

Weather models are hinting at the "classic" eastern Prairies severe weather pattern this weekend. A strong upper trough will move across western Canada with a surface low lifting out of Montana. I'm keeping a close eye on how this plays out! #mbstorm #skstorm

Thunderstorms are expected to begin redeveloping this afternoon in southern Manitoba. Some storms could be severe once again, but the tornado threat is lower than yesterday. Here are predicted storm locations at 5 pm from the @weatherlogics.bsky.social convection-allowing model.

The risk of severe weather will continue across southern Manitoba tomorrow. Storms are less likely to produce tornadoes, but hail, strong winds, and heavy rain will remain threats. #mbstorm

A dangerous storm with tornado potential is located over the Riding Mountains between Wasagaming and McCreary as of 2:40 pm CDT. #mbstorm

Dangerous thunderstorms have developed in western Manitoba. Take shelter if they approach! #mbstorm

Severe thunderstorms are possible today in eastern SK and southern MB, developing this afternoon and continuing into the evening. The strongest storms could produce tornadoes as shown by the white hatched area. #mbstorm #skstorm

Tomorrow looks to be the first significant risk of severe weather this year across southern Manitoba. Dangerous thunderstorms are possible, with a risk of tornadoes. Stay alert to rapidly changing weather! #mbstorm

A dust storm is moving across southern Manitoba this afternoon. The leading edge of the most significant dust is entering Portage la Prairie right now. It will spread across the Red River Valley this evening.

It's hang onto your hats weather today across the southern Prairies. A strong low pressure system moving across the region is responsible for the high winds:

Thanks to the awareness, and the assistance from @scottdkehler.bsky.social, I just wrote a @theactionnetwork.bsky.social letter: Reverse the Loss of ECCC Severe Weather Radar Science. Write one here: actionnetwork.org/letters/reve...

It's Emergency Preparedness Week, and your help is needed on a related letter-writing campaign. ECCC has decided to shut down its long-standing radar research program. This affects severe weather warnings, and the work of the NTP and its partners. Details here: actionnetwork.org/letters/reve...

A potent spring storm is bringing heavy snow to the western and northern Prairies. Here's a model animation showing precipitation over the next couple days (model data from the 4 km Weatherlogics WRF):

Winnipeg has recorded a double-digit high for the first time in 2026. Up to 1PM the high was 11.0 C. Normal or above-normal temperatures are expected to continue into early next week.

Another blast of wintry weather is on the way tomorrow. Snow and blowing snow is expected starting in the morning and lasting through the afternoon, improving in the evening. However, this will signal a pattern shift to much warmer weather for the second half of the week.

It is the 60th anniversary of Winnipeg's March 1966 blizzard - one of the worst in the city's history. Officially, 36 cm of snow fell, along with wind gusts up to 113 km/h. Here's the weather map from March 4, 1966:

A strong cold front will roar across southern Manitoba tomorrow morning, dropping temperatures and ushering in strong northwesterly winds. Expect heavy blowing snow with poor visibility in open areas - highway closures are possible as a result. #mbstorm

Here's a map showing estimated total snowfall yesterday across the eastern Prairies. Significant snow fell throughout a large part of SK and southern MB. However, in Winnipeg it felt like a non-event. As the map shows, Winnipeg ended up right at the very edge of the heavy snow.

Congratulations, you've made it through the worst of winter in southern Manitoba. The first half of February will be much warmer! This week starts chilly, but by Thursday we should be around the freezing mark.

The wind chill hit -51 in Winnipeg this morning, which is a record low for Jan 25. That was due to a combined air temp of -38 C and 15 km/h winds. Readings of -50 and lower are uncommon. The coldest ever wind chill in Winnipeg was -57.

The low in Winnipeg this morning was -38.2 C. The -40 C mark contains to elude the city, with the last such reading now almost 20 years ago, on February 5, 2007. The provincial cold spot was Wasagaming, with a low of -43.0 C!

Extreme cold this morning in Manitoba. Here are some of the locations that dropped below -40 C: Wasagaming: -42.3 C Flin Flon: -42.1 C Shoal Lake: -41.8 C Roblin: -41.2 C The Pas: -40.9 C Grand Rapids: -40.9 C Extreme cold will recur again tonight.

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.

Visibility in the Red River Valley is now near zero at times due to heavy snow and blowing snow. Winds will continue to increase this afternoon. #mbstorm

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!

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.

Weatherlogics users report freezing rain with this initial band of precipitation that is moving across southern Manitoba. Watch for slippery conditions today before the heavy snow and wind begins tonight!

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.

Winnipeg has set a new daily high temperature record today. The high up to 10:39 am was 5.9 C, beating the previous record of 5.6 C set in 1877. Even warmer temperatures are being reported elsewhere, with values of 7-8 C in Morden/Portage/McCreary.

A wild week of weather is on tap for southern Manitoba, starting tonight: - An Alberta clipper will bring a chance of freezing rain tonight and early Tuesday. - Tuesday will see near-record highs as a mild Pacific air mass sweeps in. continued...

Some cold temperatures in the Yukon today - even by arctic standards! These are air temperatures only, not the wind chill:
