The second half of the work week will bring variable cloudiness with seasonal temperatures to Winnipeg.

Winnipeg will see fairly cloudy conditions today and tonight, a result of a persistent southwesterly upper-level jet over the region. Several disturbances will move through the region, bringing plenty of cloud cover and a few showers. While Winnipeg will see the cloud, any rain – what little may fall – will likely stay south of the city. With the generally cloudy conditions, temperatures should climb to a high near 23°C in the city. The winds should stay light out of the west or southwest. Much of the cloud will stay in place tonight with lows dipping to around 13°C.

Thursday will bring mixed skies as the cloud cover slowly clears out of the region. With more sunshine, temperatures will end up a bit warmer with a high near 25°C. Winds will again be relatively light at 10 to 20 km/h out of the northwest. Skies should clear out on Thursday night with temperatures dropping to a low near 13°C again.

On Friday, a ridge of high pressure will begin building into the province. As it moves in, it will bring mainly sunny skies and a high temperature near 24°C. Winds will pick up out of the north into the 15 to 25 km/h range in the morning. The high will continue building into southern Manitoba on Friday night, bringing clear skies and a seasonably cool low near 9°C.

Long Range Outlook

Heading into the weekend, upper-level ridging will begin developing as a cold low over the northern Prairies shunts off into eastern Canada. This will begin to push daytime highs back into the upper 20s with a developing southerly flow. With mostly sunny conditions expected on Saturday alongside the heat, the weekend looks set to bring some very pleasant summer weather!

On Sunday, things are forecast to become more unsettled as a train of shortwaves eject from an upper trough over the west coast and begin flattening the upper ridge. The first half of next week will likely bring several rounds of thunderstorm activity to the region, possibly every day between Sunday and Wednesday. Nocturnal convection is difficult to pin down at the best of times, so right now there’s no saying whether Winnipeg will see thunderstorms/rain or not. Just keep in mind that the possibility for them will begin to increase Sunday into the start of next week.

Before then, though, enjoy some relatively pleasant summer weather!

Today’s seasonal daytime high in Winnipeg is 25°C while the seasonal overnight low is 13°C.

Seasonably warm weather is on tap for Winnipeg through the rest of the week. The city will see plenty of sunshine until cloudier conditions arrive on Friday.

Today will bring almost a repeat of yesterday too Winnipeg. The city will see a sunny start to the day give way to partly cloudy skies midday. Temperatures will be warm again with a high near 28°C with westerly winds up to around 20 km/h. There will be a chance of a thunderstorm in the afternoon, but it’s very slight. Almost all the activity today will occur along a trough of low pressure through the Interlake into western Manitoba. That said, keep an eye out just in case a rouge cell develops this afternoon. Skies will clear this evening as temperatures dip back to a low near 13°C.

Thursday will bring beautiful summer conditions to the city as a ridge of high pressure moves through. Temperatures will climb to a high near 29°C under partly cloudy skies. Winds won’t be an issue either as the ridge keeps them light out of the north. Skies will remain partly cloudy on Thursday night with a low near 14°C.

Friday’s forecast has some uncertainty as it’s largely dependent on the evolution of a convective system on Thursday night. Right now, it looks like an area of thunderstorms will collapse near the Saskatchewan border on Friday morning. The clouds associated with this system will drift eastwards, spreading into the Red River Valley midday. Once they arrive, Winnipeg will see mixed to cloudy skies with temperatures climbing to a high near 26°C. The city will see mixed skies on Friday night with temperatures dropping to a low near 15°C.

If the convection develops differently on Thursday night and the city doesn’t see as much cloud as expected, temperatures will be warmer and could reach as high as 29 or 30°C.

Long Range Outlook

Winnipeg will see variable cloudiness this weekend with a chance for showers or thunderstorms with the best chance on Saturday night into Sunday morning. It will be a hot weekend, too, with daytime highs in the low 30s and overnight lows in the upper teens.

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