Temperatures Soaring For the Weekend

After a week bringing welcome reprieve from the heat, more rain than Winnipeg has seen in months, and some clean air back to the region, sun and summer heat will return this weekend.

Winnipeg will see one more seasonably cool day today as an upper trough exits the region. Temperatures will climb into the low 20s with light northwest winds. A few morning clouds will clear out for the afternoon leaving sunshine and a pleasant summer day. Tonight will bring seasonal temperatures down to the low teens and clear skies.

An upper ridge will build across the province this weekend, bringing light winds on Saturday strengthening to moderate southwesterlies on Sunday. Temperatures will climb into the low to mid-30s both days with plenty of sunshine. Humidity levels should stay comfortable through the weekend.

Very warm temperatures will spread back across the southern Prairies this weekend.

This system will also bring very warm nights to the region with lows climbing to the upper teens on Saturday night and low 20s on Sunday night.

Fortunately, the region should stay smoke-free for the weekend. Smoke models show no notable smoke levels right through into Sunday. That said, there’s a chance some hazy conditions could return to the region late Sunday into Monday, sourced from the wildfires over southern British Columbia.

All in all, it will be a hot and beautiful summer weekend across southern Manitoba.

Long Range Outlook

Conditions are forecast to turn more unsettled next week beginning on Tuesday and persisting much of the week. Temperatures will gradually ease back towards seasonal values with several chances of showers or thunderstorms over a multi-day period.

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

Hot Conditions Return to Southern Manitoba

An upper ridge will bring hot summer weather back to southern Manitoba this weekend.

Another very warm air mass building into the region will send temperatures in Winnipeg back into the low 30s this weekend. Alongside the heat, an upper ridge building across the Prairies will keep skies mainly clear over the next few days.

A weak ridge of high pressure draped across southern Manitoba will also keep winds light the next couple days. Winnipeg should see a bit of wind by Sunday afternoon, but only southerlies to around 20 km/h.

Manitoba will see very warm temperatures on Sunday with highs in the low 30s through most of the province.

Overnight lows will warm to around the 20 °C mark for the weekend, but humidity levels should stay fairly comfortable through the weekend.

Long Range Outlook

Forecasts show next week starting with unsettled conditions as a couple disturbances move through the region. Unfortunately no widespread rain can be guaranteed for the Red River Valley; these systems will more likely produce scattered showers and thunderstorms rather than broader areas of rain.

Forecasts show temperatures breaking back to seasonal values mid-week, then climbing back to the low 30s for next weekend.

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

Summer Warmth Gradually Returns

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.

Summer heat will spread back across the Prairies by the end of the week with highs in the low to mid-30s in northern Manitoba and upper 20s in the south.

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.

Cooler Weather Ahead

Winnipeg will see relief from the heat this week as an Arctic high brings slightly below seasonal temperatures to the region.

A series of cold fronts sweeping through the province over the last 24 hours are ushering in cooler temperatures from the north, bringing an end to the intense heat that’s been in place over the region. This cooler air mass will be brought by a sprawling Arctic high building into the Prairies.

Winnipeg will see a seasonably warm day today with a high near 26 °C under mainly sunny skies. Winds will pick up out of the north into the 30–40 km/h range for the afternoon. The clouds will thicken up heading into the evening as an upper-level disturbance pushes into the region. Another cold front will push through at the surface tonight, keeping winds up at around 20 km/h. This upper-level disturbance will bring a chance of rain to the city, but the cold front will likely shunt everything southwards a bit. It’s likely that the rain moving through will just glance Winnipeg, or move completely south of the city. Temperatures will head to a low near 11 °C.

The southern Prairies will see seasonably warm conditions today, but a cold front pushing southwards will bring cooler temperatures for Tuesday.

Winnipeg will find itself behind a second cold front on Tuesday with much cooler weather. Temperatures will climb to a seasonably cool 21 °C with partly cloudy skies as the overnight system clears out. The wind will keep put out of the north-northeast at 20–30 km/h. These winds may bring plumes of smoke into the region from fires burning east of Lake Winnipeg. How thick the smoke ends up being depends on a lot of nuance. If you have sensitivities to smoke, be sure to keep on the lookout for any special air quality statements issued by ECCC. Winds will ease Tuesday night with temperatures heading to a low near 10 °C.

Winnipeg will see plenty of sunshine on Wednesday with a near-seasonal high near 25 °C. Winds will be light through the day, and any smoke is left in the area should clear out early. Otherwise, it should be a beautiful day for the city. Temperatures will head to a low near 14 °C on Wednesday night with an increasing southerly wind.

Long Range Outlook

Unsettled conditions will develop over the region on Thursday as a warmer air mass begins to return. Winnipeg will see cloudier conditions on Thursday with a chance of showers, followed by a bit more sun and warmer temperatures on Friday. The heat is back for the weekend with highs in the low 30s and overnight lows in the upper teens.

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