Sunshine Returns as Temperatures Warm Up

Winnipeg will finally see the sun for a couple days as the cooler temperatures break across the region and some summer warmth builds back in.

Mild temperatures will spread into southern Manitoba on Wednesday with daytime highs in the low to mid-20s.

A brief note to start: the absence over the past couple weeks wasn’t planned. I caught COVID and it ended up being a rough ride that’s taken a while to recover from. I’m getting back into form now and hope to move back towards posting with more regularity again.

That said, I’m back with good news. After a large cool and wet couple weeks, the weather will finally turn a corner today. A large area of high pressure will descend from the Arctic into Manitoba today, while an upper ridge builds into the Prairies. This will settle the weather and bring sunny skies to the region as northerly winds ease. It will be seasonably cool today with a high in the 15 to 20 °C range and an overnight low near 5 °C.

Warmer weather will arrive tomorrow as the high pushes off to the east and a deep southerly flow develops. A broad area of southerly winds from 30 to 50 km/h will develop across southern Manitoba and southeast Saskatchewan, sending highs into the low to mid-20s. As the upper ridge moves over the region on Wednesday night, temperatures will stay mild with lows dipping to the mid-teens.

As the upper ridge moves east, a deep upper trough will follow in its wake, spreading unsettled conditions through Alberta and Saskatchewan. Widespread thunderstorm activity will develop in those areas on Tuesday and Wednesday as the system progresses.

By Thursday, the upper trough will be pushing into Manitoba. Down at the ground, this system will show as a low pressure system over northern Saskatchewan with an occluding frontal wave dropping southwards into the American Plains. The region will see cloudier conditions on Thursday as this disturbance moves through, and a band of [thunder]showers is likely to develop and move across the Red River Valley on Thursday afternoon. Temperatures should be near-seasonal with a high in the low 20s and an overnight low on Thursday night in the 10 to 15 °C range.

Long Range Outlook

Conditions will settle for the end of the week with highs in the low to mid-20s on Friday, Saturday, and Sunday. The region will likely see a mix of sun and cloud through all three days, but there may be a chance of isolated showers on Friday and Sunday.

Next week looks to start with more of the same! Seasonal temperatures, variable cloudiness, and occasional chances for showers.

Today’s seasonal daytime high in Winnipeg is 22 °C while the seasonal overnight low is 8 °C.
