Another Heat Wave Ramps Up

Brad Leave a comment

Winnipeg will see temperatures climbing back towards the mid-30s this week as another heat wave is set to develop over the region.

Winnipeg will move into another extended period of hot, dry weather over the coming days. An upper ridge will gradually amplify over the rest of the week, producing another broad area of clear skies with increasingly hot weather.

Before the warmer weather starts, the city will see one more “cool” day. Skies will be a bit cloudier this morning with a few showers or thunderstorms drifting into the Red River Valley. Most of this activity will pass to the south of Winnipeg, but there is a chance for the city to see a shower or thunderstorm in the first half of the day. Skies will clear for the afternoon with temperatures climbing to a high near 29 °C. Skies will stay mainly clear tonight with a low near 15 °C.

Very warm temperatures will develop over the southern Prairies on Friday.

The rest of the week will bring warming temperatures and mainly clear skies. As the upper ridge amplifies, daytime highs will climb to 35 °C by Friday. Overnight lows will warm to around 20 °C. Winds will be light on Thursday, but southerlies will pick up to around 20 km/h on Friday.

Hazy skies will linger through the region this week.

Long Range Outlook

Temperatures will stay in the mid- to upper-30s through the weekend and right through next week. While there may be the periodic chance of showers or thunderstorms, little to no organized rainfall potential is in the forecast.

The hot, dry conditions will continue to worsen the drought over the region and push more regions into an extreme fire danger. While smoke plumes can be difficult to forecast beyond short time ranges, it’s highly likely that southern Manitoba will continue to see varying amounts of smoke moving through the region.

Drink lots of water, check on those who may not be able to protect themselves from the heat as well, and stay safe!

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

Hot Weather Continues

Hot and increasingly dry conditions will continue to be the weather story for Winnipeg and the Red River Valley.

It’s only going to get drier across the Red River Valley this week as intense summer heat bakes the region. Winnipeg will see highs hovering around 30 or 31 °C through the first half of the week with lows in the upper teens.

Winds will be breezy out of the south today with southerly winds of 30–40 km/h picking up this morning. A trough will push across the region today, and while it supported widespread thunderstorms overnight, it will be less active as it moves into the Red River Valley. Winnipeg will see a chance of showers or thunderstorms beginning around lunch and persisting until early evening. If any thunderstorms are able to develop, they will have a small chance of producing severe hazards with primary threats of damaging wind and/or hail.

Winnipeg’s “cooling off” this week will be to highs near 30 °C. Hotter temperatures will return later this week.

Behind this trough, winds will shift to the northwest and then ease overnight. The northwesterly flow will usher in smokier conditions to the region once again. This time, the smoke will be coming from fires burning over northern Saskatchewan.

Tuesday and Wednesday will each bring light north-northeast winds and only a few clouds. The smoke, however, will likely stick around. While near-surface conditions will improve a bit, quite a bit of smoke will likely linger aloft over the region, casting that familiar slight orange hue under hazy skies.

Long Range Outlook

Another surge of hot air will move into the region for the second half of the week. Daytime highs will climb towards the mid-30s by the end of the week with overnight lows near 20 °C. While a couple shortwaves may meander over the region, an amplifying upper ridge should also keep the clouds at bay.

The forecasts show no notable precipitation for the Winnipeg area in the second half of the week or the weekend.

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

Brad Leave a comment

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.
