This weekend will bring the warmest weather so far this year to southern Manitoba.

Winnipeg has had a couple mild days this spring, but none that will compare to the heat that builds into the region this weekend. With a cooler Thursday behind us, yesterday’s northerlies will be replaced with light westerlies as milder Pacific air begins to push east. Today will trend cooler with a high in the low teens as the region transitions out of the colder air that moved into the region. While the day will start with cloud in the region, it should break up and move out for the afternoon.

Temperatures will dip into the 5–10 °C range tonight under clear skies as light winds shift southerly.

Heading into the weekend, the early-season heat is on with mainly sunny skies through the weekend. Saturday will bring daytime highs into the mid-20s while Sunday will likely be warmer with highs in the mid- to upper-20s . Winds will shift westerly through Saturday but should remain light. On Sunday, the winds will strengthen from the south to as high as 40 gusting 60 km/h. Those winds will ease into the 20 to 30 km/h range on Sunday night. Overnight lows in both nights should sit in the 10 to 15 °C range.

Long Range Outlook

The warm weather will stick around for Monday, then ease to seasonal values for a couple days before more heat builds back into the region. No significant precipitation is in the forecast.

Today’s seasonal daytime high in Winnipeg is 16 °C while the seasonal overnight low is +2 °C.
