After a cool and smokey interlude to the week yesterday, fresher air and warmer temperatures will return to the region for the second half of the week.

An upper ridge building across the Prairies will shape the weather this week. As it pushes eastwards, a southerly flow will begin to push warmer air from the south back into the region.

Today, Winnipeg will see light winds and perhaps a bit of lingering smoke from the forest fires east of Lake Winnipeg. Temperatures will return to a near-seasonal high of 25 °C under mainly sunny skies. A light southerly wind will persist tonight at 15–25 km/h with a low 13 °C.

On Thursday, Winnipeg will see a bit more cloud as a weak disturbance pushes towards the province from Saskatcehwan. Southwestern Manitoba will likely see showers through the day, but they will struggle to move into the Red River Valley. A dry southerly wind around 30 km/h will develop in the morning and, combined with a lack of upper support, will weaken the showers as they move east. There’s a chance for a few drops here and there, but any accumulating shower activity should stay further to the west. Tmeperatures will reach a near-seasonal high around 26 °C. The city will see partly cloudy skies on Thursday night with diminishing winds and a low near 15 °C.

Friday will bring slightly warmer temperatures to Winnipeg with a high near 28 °C and a light southeast wind. The disturbance that will bring the unsettled condtiions on Thursday is forecast to stall out over Saskatchewan. As a result, southwestern Manitoba will likely see some scattered showers, but skies should clear in Winnipeg through the day. Tmeperatures will head to a low near 17 °C on Friday night with clear skies.

Long Range Outlook

It will be a hot weekend in Winnipeg with highs climbing back into the low 30s. The city will see mainly sunny skies throughout and overnight lows around 20 °C. The forecast is absent of any notable precipitation for the Red River Valley. The hot weather will continue into next week, but conditions may become a bit more unsettled. There may be better chances for some showers and/or thunderstorms heading into the week.

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

Summer heat arrives this week for Winnipeg with a prolonged stretch of hot, dry weather.

The weather driver for Winnipeg this week will be a potent upper-level high that is currently situated over British Columbia. This feature is responsible for a dangerous, record-setting heat wave over the region right now. In fact, yesterday the town of Lytton, B.C. set a new record for hottest temperature recorded in all of Canada at 46.6 °C, beating out the previous record of 45.0 °C set in both Yellow Grass and Midale, SK on July 5, 1937. And records aren’t just falling in British Columbia, they’re being smashed by 5–10 °C.

This feature will slowly drift eastwards this week, gradually weakening as it pushes across the Prairies. But it will continue to bring several days of record-shattering heat to British Columbia and Alberta.

Winnipeg will see daytime highs climb to around 30 °C over the coming days with lows increasing into the upper teens. The city will see plenty of sunshine over the next few days with just a few clouds around. Winds will pick up out of the north to around 20 km/h today, then ease tonight and stay light over the next couple days. As mentioned at the top, no notable precipitation is in the forecast. There is a slight chance that a few showers may move through overnight Tuesday or very early Wednesday morning, but it doesn’t look particularly likely at this point.

Long Range Outlook

The rest of the week will be more of the same with temperatures increasing further. Highs should reach the mid-30s by the weekend with overnight lows warming to around 20 °C. No precipitation is expected through the second half of the week.

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

Winnipeg will see beautiful summer weather this weekend.

The next few days will bring seasonably mild temperatures to Winnipeg as a major upper high gradually pushes into the western Prairies. This feature will bring what will likely be a record-shattering heat wave to portions of western Canada and the western United States. That heat will take longer to reach Manitoba, though, leaving the province with generally seasonable late June conditions.

A weak ridge extending across the southern Prairies will help keep winds light out of the southwest today. Winnipeg should see partly cloudy skies for much of the day with a high near 27 °C. The city will see clear skies tonight with light winds and a low near 15 °C.

On Saturday, one last upper trough will rotate into southern Manitoba, pivoting around the broad Arctic vortex over Hudson Bay. It will bring mixed skies to the region midday into the afternoon along with a chance of showers.

There may be a chance for isolated thunderstorms, but both energy and wind shear will be in short supply. This means that if any thunderstorms are able to develop, they will likely be short-lived and won’t pose any severe weather threat. Winds will pick up out of the west-northwest for the afternoon at 20–30 km/h. Temperatures will still be warm with a high near 26 °C. Winnipeg will se a low near 13 °C under mostly clear skies on Saturday night.

Sunny skies return for Sunday with temperatures climbing once again to a high near 26 °C. Winds will be light out of the north through the day. A few showers will move through the province on Sunday, but there is strong agreement that they’ll stay west of the Red River Valley and move through the Parkland into southwestern Manitoba.

Skies will stay mostly clear on Sunday night with a low near 15 °C.

Long Range Outlook

The upper high building over western Canada will slowly push eastwards into the Prairies over the coming week. This will result in a gradual increase in temperatures next week with highs increasing into the low 30s. The city should see fairly sunny conditions, however the occasional chance for showers can’t be ruled out.

Some forecast models are suggesting that a cutoff low will develop over the Northern Plains of the United States. If this happened, then there is the potential that a high over low block could develop. These are generally very stable patterns, and could result in a prolonged period of hot, dry weather over the region.

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