Strong thunderstorms have started to develop this evening in south-central Manitoba. These storms are likely to expand in coverage later this evening and shift eastward. The Red River Valley and southeast will also be at risk of severe storms this evening and overnight. #mbstorm

The cold front has made its way through Winnipeg, dropping the temperature from 34 C at 6pm to 27 C at 8pm. The humidex dropped from 45 at 6pm to 30 at 8pm. #mbwx

A cold front is advancing across southern Manitoba today. However, it's a pretty lazy front and isn't moving very fast. For most of southern MB it will be another hot/humid day. Even for areas behind the front, the cooler/drier air is slow to arrive.

Elm Creek, Manitoba with an astounding 29 C dewpoint this evening. As recorded by the Manitoba agriculture network.

Another 24 hours of extreme heat and humidity is on tap for southern Manitoba before a cold front arrives later tomorrow. It will sweep away the worse of the heat/humidity. Tuesday will still be fairly warm, with highs in the mid-upper twenties, but much lower humidity.

It’s currently 35 C with a dewpoint of 27 C at my house just outside Winnipeg. That gives a perfect 50 for the humidex. Highest I’ve ever recorded with my weather station. #mbwx

Three days of oppressive heat are on the way for southern Manitoba: Saturday: Highs 31-34 C; Humidex 40-45. Sunday: Highs 33-37 C; Humidex 41-47. Monday: Highs 32-35 C; Humidex 40-46. A cold front will push across southern Manitoba on Monday, putting an end to the heat.

All of southern Manitoba should be prepared for heavy rain later today. An extremely humid air mass will result in widespread thunderstorm activity starting this evening, with the potential for flash flooding. #mbstorm

The Prairies will get no break from rain as yet another powerful system is set to arrive this weekend. The 5-day average of all weather models (below) has many large areas of 50-100 mm. However, do not be surprised to see pockets that receive 100-200 mm.

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

Scott Kehler 🇨🇦 @scottdkehler.bsky.social · 10/06/2026

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

Scott Kehler 🇨🇦 @scottdkehler.bsky.social · 10/06/2026

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

Scott Kehler 🇨🇦 @scottdkehler.bsky.social · 10/06/2026

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.

Scott Kehler 🇨🇦 @scottdkehler.bsky.social · 10/06/2026

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

2154

Scott Kehler 🇨🇦 @scottdkehler.bsky.social · 10/06/2026

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

Scott Kehler 🇨🇦 @scottdkehler.bsky.social · 10/06/2026

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

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

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

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:

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.

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.
