Temperatures will continue well above-seasonal in Winnipeg and the Red River Valley for a couple more days before a cold front sweeps through, shifting conditions back to a near-seasonal pattern.

A warm front that moved across the province yesterday afternoon and overnight has brought even warmer air into the province that will send temperatures soaring to highs in the low 30’s today. Winds will remain light and morning sun will develop into partly cloudy skies this afternoon. All in all, a beautiful summer day is in store for Winnipeg & the Red River Valley. Expect temperatures to dip to a low near 17°C tonight with just a few clouds and a light south wind at around 15 km/h.

Tuesday will see temperatures once again climb towards the 30°C mark, but highs will be a bit cooler than Monday — around 29°C in Winnipeg, but possibly in the low 30’s closer to the US border — as the warmest air is shunted out by a cold front sweeping southwards through the province. Winds in Winnipeg will shift to westerly at around 15-20 km/h midday and then to northwesterly at around 30 km/h in the afternoon as the cold front moves through. Little rain is expected with the front in Winnipeg, but east into the Whiteshell and south and southwestwards into Sprague and portions of the southern Red River Valley, some thunderstorm activity will be possible in the afternoon. The cloud will clear out for the evening as temperatures head to a low near 13°C and winds diminish.

One thing to note is that when the cold front passes through on Tuesday, it’s possible that there will be some amount of smoke that moves into the region behind it from a large fire burning in eastern Saskatchewan. By the time it reaches here it will likely be fairly diffuse, but it may be thick enough to be noticeable.

Wednesday will be a pleasant day with plenty of sun, a high near 24°C and winds out of the east at 15-25 km/h. Temperatures will dip down to around 13°C on Wednesday night.

Long Range

The remainder of the work week looks quite nice with highs in the 25 to 28°C range. Thursday will bring sunny skies, but with an increasing southerly wind ahead of the next low pressure system crossing the Prairies. Friday will bring continued breezy southerly winds, more cloud, and the potential for showers or thunderstorms as the low crosses the province. Winds shift to the northwest for Friday night and then after scattered showers on Saturday, several days of below-seasonal temperatures look to move into the region.

Winnipeg’s seasonal daytime high is currently 23°C while the seasonal overnight low is 10°C.

While the past few days have been pleasant with above-normal temperatures, more significant warmth will be moving back into Southern Manitoba over the coming days as an upper-level ridge builds into the region.

Today will echo yesterday weather-wise, with high temperatures near 8°C and partly cloudy skies. A ridge of high pressure centred over southern Manitoba will ensure that winds remain light, making for a fairly nice day overall. Skies will be mainly clear tonight as temperatures dip to a low near -4°C.

Thursday will be bring the push towards warmer temperatures as the upper-level ridge starts building into the province and a light southerly flow develops. Daytime highs will reach around 11°C with continuing sunny skies. With mainly clear skies, temperatures will dip down to about +2°C on Thursday night.

Southerly winds will ramp up on Friday to 30-40 km/h, ushering in a much warmer air mass that is being pulled northeastwards by a develop low pressure system moving across Saskatchewan. Skies will remain mainly sunny for much of the day as temperatures climb to a high near 16 or 17°C. Late in the day, cloud cover will begin working into the region from the west as a warm front moves eastwards across the province. With even warmer air on the way into the region, temperatures will remain quite mild on Friday night with lows dropping to only about 7°C.

Long Range

The weekend is looking quite nice with temperatures soaring into the upper teens on Saturday with lighter winds than Friday shifting from southerly to westerly through the day. Some weather models give a chance for some showers on Saturday, but the general consensus [at the moment] is that we’ll see mixed to cloudy skies, but remain dry. The warm weather continues on Sunday, but not quite to the same extent.

Heading into Sunday night, a couplet of low pressure systems, will move into the region, spreading precipitation northwards into southern Manitoba through the night. As it stands currently, it appears Winnipeg will only see a few mm of rain before things switch over to snow. It’s still very early for details, however. In general, it seems likely that many places in the Red River Valley could see up to 5 mm and then anywhere from 5 to 15 cm of snow. This system will likely also carry with it a brisk northeasterly wind, which will produce [potentially significantly] higher amounts near the western escarpment of the Red River Valley.

That said, there is some uncertainty as to whether or not this will actually materialize. We’ll be keeping a close eye on things as they develop and have more details heading into the weekend. Until then, enjoy the warmth!

Winnipeg’s seasonal daytime high is currently 7°C while the seasonal overnight low is -4°C.

Above-normal temperatures will continue throughout Winnipeg & the Red River Valley, but with a difference: sunshine.

A nice change in the forecast today: it’s fairly simple! The coming few days will continue to bring above-normal temperatures across southern Manitoba, with daytime highs near 12°C today sliding towards highs of 6 or 7°C for Tuesday & Wednesday. There will be plenty of sunshine today with skies then giving way to more mixed conditions for Tuesday and Wednesday.

The weather also looks fairly dry over the next few days. There will be a slight chance of an isolated light rain shower or two on Tuesday afternoon as a weak disturbance moves through the southwestern portion of the province.

Long Range

The remainder of the week looks beautiful with an upper-level ridge building into the region, bringing another surge of well above-normal temperature to the region. It appears that daytime highs will climb back into the low teens with sunny to mixed skies and no rain expected.

Winnipeg’s seasonal daytime high is currently 6°C while the seasonal overnight low is -5°C.
