A broad area of high pressure moving into Manitoba will bring seasonal temperatures and plenty of sunshine for the weekend.

It will be quiet weather for Winnipeg and area over the next several days as a broad area of high pressure builds eastwards across the Prairies. This system will bring daytime highs in the low 20s to the region over the next few days with overnight lows in the 5–10 °C range. The days will bring light northerly winds with calm conditions at night. And most days will bring morning sun that gives way to a few afternoon clouds.

Some fog patches could be possible overnight on some of the upcoming nights as well.

There’s also no notable chance of precipitation right through the weekend.

Long Range Outlook

Heading into next week, the seasonal temperatures will continue right through the week . A low pressure system could move into the region mid-week, bringing southerly winds, warmer temperatures, and a chance of showers.

All in all, there’s lots of pleasant September weather ahead, so hopefully you can get out there and enjoy it!

Today’s seasonal daytime high in Winnipeg is 20 °C while the seasonal overnight low is 8 °C.

A warmer air mass will gradually push into southern Manitoba this week with highs back in the upper 20s for the second half of the week.

An upper ridge building into the eastern Prairies will bring seasonably warm temperatures back to the region. Before that happens, though, there will be one more day of seasonal warmth in Winnipeg as a disturbance passes by. It will bring mixed skies to the region today with highs climbing into the mid-20s. Winds won’t be much of an issue either, climbing into the 20–30 km/h range out of the south.

Smoke will be a bit of an issue this morning, but air quality should improve as the day progresses.

Tonight will be clear and cooler with a low temperature around 10 °C.

On Wednesday, the heat will begin to push into the region as a warm front edges into the region. Winnipeg should see a high in mid- to upper-20s with sunny skies. Winds won’t be too much of an issue, again climbing into the 20–30 km/h range out of the south. The region will see clear skies on Wednesday night with a low in the mid-teens.

On Thursday, a low pressure complex will begin lifting through Saskatchewan and the Dakotas towards the province. Highs will likely be a couple degrees warmer than Wednesday with cloud working into the region for the afternoon. The wind will be a lot more noticeable on Thursday, picking up out of the south into the 40 gusting 60 km/h range. This system will bring some showers or thunderstorms to western Manitoba in the morning. Those showers will lift to the north, then instability will build eastwards through the day.

By late-afternoon, a risk of thunderstorms will develop over the Red River Valley and areas east. There is a slight risk of severe thunderstorms; with 500–1000 J/kg of MLCAPE and 40–50 knots of bulk shear, any thunderstorms that develop would likely become fairly well organized with a primary threat of damaging hail and wind gusts. The risk of thunderstorms will continue into the evening, gradually shifting eastwards as the night goes on.

Long Range Outlook

Settled conditions will return to southern Manitoba on Friday with highs again in the upper 20s. On the weekend, even more heat will build into the region with daytime highs climbing into the low 30s.
