Summer Heat Continues

Brad Leave a comment

Temperatures will soar in Winnipeg over the coming days as an early-season blast of summer heat moves through.

Temperatures will soar this afternoon in Winnipeg as southerly winds of 30 gusting 50 km/h continue to push heat out of the United States. Before it warms up, though, the city may end up seeing some cloudy periods this morning as an area of stratus cloud clips by the region. Once that leaves the region, temperatures will climb to a high near 28°C this afternoon. Temperatures will dip back down to mild low near 18°C tonight with southerly winds of 20 to 30 km/h.

Thursday will bring mixed skies to the city with continued southerly winds near 30 gusting 50 km/h. Temperatures will continue to be seasonably mild with ah high near 26°C. Late in the day, more cloud cover will move into the region bringing with it a slight chance of showers. Temperatures will head to a low near 16°C with mostly cloudy skies.

Summer heat will once again be in place over southern Saskatchewan and Manitoba today.

Slightly unsettled conditions will continue over the region on Friday. Skies will stay on the cloudier side as temperatures climb to a high in the mid-20’s. Friday will bring the first organized thunderstorm risk to the Red River Valley, although it may end up staying to the west near the escarpment and into the southwestern corner of the province. The city will likely see a chance of showers or thunderstorms through the day, though. Those unsettled conditions may end up persisting through Friday night as well. Temperature should dip to a low near 14°C.

We’ll end up taking a closer look at Friday’s thunderstorm potential in our next forecast post!

Long Range Outlook

Saturday should bring another day of warm temperatures, then a push of cooler air will move in for Sunday. The latter half of the weekend will see highs head back to the teens with a good chance of rain. Things rebound nicely for Monday and Tuesday, then more unsettled weather is possible mid-week.

Today’s seasonal daytime high in Winnipeg is 21°C while the seasonal overnight low is 6°C.

Breezy Conditions Usher in Summer Heat

Winnipeg will rapidly switch to full summer mode as breezy southerly winds usher in markedly warmer temperatures.

What a difference a week makes! Just last Monday temperatures were as low as -10°C with highs struggling to reach a well below-seasonal 8°C. Now, temperatures will continue to climb as summer settles into the region. A slow-moving low over the western Prairies will support a southerly flow over Manitoba through the coming week, pumping heat northwards out of the American Plains.

Summer heat will spread across southern Saskatchewan and Manitoba this week.

Winnipeg will see daytime highs in the mid-20s over the next few days while overnight lows slowly climb into the upper teens.

The city will also see plenty of sun over the next few days. Skies will be partly cloudy today with a bit more cloud in the morning than the afternoon. Skies should stay mainly sunny on Tuesday, then a bit more cloud moves in for Wednesday with mixed skies.

Long Range Outlook

The warm weather will continue through the rest of the week, but with increasingly unsettled conditions. By Friday, the region will likely see the chance for scattered showers or thunderstorms. A cold front is forecast to push through late Saturday, bringing near-seasonal temperatures back to the region for Sunday with another chance of showers.

Winnipeg will see temperatures climb into the 20’s this weekend as the Arctic grip on the region finally ends.

The city will see one more cool day as a ridge of high pressure moves through the region behind yesterday’s rain. A cold front will push through this morning, ushering in northerly winds near 20 km/h. Skies will stay mainly sunny as temperatures climb to a high near 15°C. Winds will ease this evening with a low tonight near +4°C. A few clouds will move into the region overnight as warmer air begins moving into the region.

On Saturday, temperatures will climb to around 21°C with partly cloudy skies. There may be a slight chance of a shower early Saturday morning as some nocturnal convection moves across southern Manitoba. While it’s always difficult predicting where exactly nocturnal convection will develop, it looks likely that any showers will stay north of Winnipeg. With light winds through the day, it will be a great day to get outside and enjoy the weather! Skies will clear on Saturday night as temperatures dip to a low near 8°C.

Some midweek rain, Winnipeg will finally see temperatures return towards seasonal values, with positively summer-like weather possible this weekend!

A low pressure system moving through southern Manitoba and the Dakotas today will bring dreary weather to the region today. Winnipeg will see cloudy skies with rain beginning later this morning. The rain will last through the afternoon, then ease through the evening. Temperatures will only climb to a high near 8°C today with southeast winds picking up to 30 gusting 50 km/h. The winds will ease tonight as temperatures head to a low near +4°C.

Rainfall amounts will vary across the Red River Valley with 2 mm likely near Portage la Prairie increasing to 10 to 15 mm over the southeastern Red River Valley. Here in Winnipeg, totals should end up near the 5 mm mark.

A cooler end to the work week looks to be in store.
