Winnipeg will continue to see relief from the smoke as a cooler air mass from the north remains in place to start the week.

Winnipeggers can breathe easy today thanks to a crisp, cool air mass that moved into the province behind a cold frontal passage on Saturday night. The city will see a smoke-free high near 23°C today with northerly winds near 20 km/h. A few clouds will move through later this afternoon. Overnight lows will be cooler than seasonal due to a ridge of high pressure moving into the region overnight. Winnipeg’s low should drop to around 7°C.

The ridge of high pressure will drop southwards through the day on Tuesday, bringing westerly winds of 15 to 25 km/h to the region. Temperatures will be cool once again with a high near 24°C. A weak upper-level disturbance will bring cloudier skies for a portion of the afternoon, but no rain is expected. Temperatures will dip down to a low near 10°C tonight under clear skies.

By mid-week, an upper-level ridge will begin moving back into the region. This will bring warmer weather and suppress any cloud cover. I don’t say sunny skies, though, because the upper-level ridge will bring a westerly flow aloft back to the region. This will likely spread smoke from the B.C. wildfires back across the Prairies. It’s too early to say exactly how smoky it will become, but expect hazy conditions at the very least, if not a return to full-fledged smoke cover. Given sunshine, temperatures should reach a high near 28°C, but if smoke returns and is relatively thick, then it could be a few degrees cooler than that. Winds will be 10 to 20 km/h out of the west-southwest.

Long Range Outlook

The remainder of the week looks increasingly warm and humid. Unsettled conditions may develop Thursday night into Friday, potentially bringing some needed rain to the region. Smoke cover may inhibit daytime highs, but it’s too early to know exactly how much impact it will have. The weekend is looking fairly cloudy with a return to seasonal temperatures.

Winnipeg’s seasonal daytime high is currently 24°C while the seasonal overnight low is 11°C.

Winnipeg will see cooler weather move in today, bringing an end to the heat wave that brought record-setting warmth to the city over the weekend. The relief will be brief, though; daytime highs will climb back into the low 30s on Wednesday.

Winnipeg will see temperatures fall through the day today as a cold front pushes through the region. Cloud cover associated with the front will move in early this morning, bringing mainly cloudy skies for much of the remainder of the day. Winds will increase out of the northwest to 30 gusting 50 km/h midday, keeping temperatures cool with a high of 23°C. The wind will gradually diminish overnight and the cloudy skies should gradually clear. Temperatures will dip down to a low near 9°C.

A high pressure system will move into the region on Tuesday, bringing northerly winds of 10 to 20 km/h and partly cloudy skies. Winnipeg’s high near 22°C will be well below-seasonal for this time of year and a far cry from the 37.5°C seen on Sunday. Temperatures will remain cool on Tuesday night with a low near 11°C and light winds.

And that brings an end to the cooler temperatures. The heat returns on Wednesday as another upper-level ridge begins building across the southern Prairies. Winnipeg should see a high near 31°C with winds out of the south-southwest at 20 to 30 km/h. Skies should remain mainly sunny through the day. Expect a low near 17°C on Wednesday night.

Long Range Outlook

The remainder of the week is looking like Winnipeg will continue to see above-normal temperatures with highs in the low 30s through the remainder of the work week. There are some hints that the weekend may bring a return to seasonal temperatures alongside some unsettled conditions, but it looks rather uncertain at this point.

All in all, it looks like a pretty nice stretch of weather coming up with near to slightly above-seasonal highs well into next week.

Winnipeg’s seasonal daytime high is currently 25°C while the seasonal overnight low is 12°C.

Winnipeg will see below-seasonal temperatures on Monday, then rebound back towards a summer sizzler mid-week with daytime highs potentially climbing above 30°C.

Winnipeg will see markedly cooler temperatures today as a ridge of high pressure builds into the region behind the cold front that moved through southern Manitoba on Saturday night. Daytime high of just 20°C will be the coolest Winnipeg has seen since June 4th when the temperature topped out at 19.7°C. The city will see some cloudy periods, but rain isn’t a concern. Winds will continue out of the northwest at 20 to 30 km/h through the day, then diminish early this evening. Under clearing skies Winnipeg will see a low near 9°C tonight.

Tuesday and Wednesday will light southerly winds as a return flow develops over southern Manitoba. Warmer temperatures will build back into the province into the middle of the week. Tuesday will see a high near 26°C, then more summer sizzle arrives on Wednesday with a high near 30°C. Skies will remain sunny on Tuesday, but Wednesday will see mixed to cloudier skies develop in the afternoon. Overnight lows will climb as the warmer air moves into the province. Lows will fall into the mid-teens on Tuesday night followed by a very mild low near 20°C on Wednesday night.

Fortunately, humidity levels will remain comfortable for the next 3 days. Muggier conditions are forecast to redevelop on Wednesday night as a more humid air mass spreads out of the Dakotas. At the moment, it doesn’t look too bad with dew points in the upper teens expected. Humidity becomes significantly more oppressive once the dew point exceeds 20°C.

Long Range Outlook

Wednesday night into Thursday morning will bring a renewed thunderstorm risk to the region. A low pressure system is forecast to move through the Dakotas and may end up moving northwards into southern Manitoba. If it does so, it will likely support an area of elevated convection on Wednesday night, then generally unsettled weather on Thursday. If the low ends up remaining south of the border, southern Manitoba should still see a fair amount of cloud, but much less rainfall.

Cloudier weather will likely stick around for part of Friday as well, then a cold front swings through and ushers in drier conditions. Temperatures should remain warm through the end of the week with daytime highs in the upper twenties and lows in the mid- to upper teens.

Winnipeg’s seasonal daytime high is currently 26°C while the seasonal overnight low is 13°C.
