Whether you’re in the middle of a home renovation that involves taking off part of your roof as I am[1], trying to harvest fields, or just trying to string together a few dry days for a camping trip, this summer continues to challenge as the threat for thunderstorms continues across the Red River Valley.

Today will be a hot one across southern Manitoba as a light southerly wind taps into a warmer air mass to our south, drawing daytime highs up to around the 30°C mark in Winnipeg. Skies will be fairly sunny until late in the day when cloud cover begins thickening up from the west.

A cold front sweeping into Manitoba through the evening and overnight will once again spread showers and thunderstorms into Manitoba. There will be a slight risk of severe thunderstorms in the late afternoon and evening hours to the north and west of the Red River Valley. This severe thunderstorm threat will shift into the Red River Valley late in the evening & into the overnight period. These thunderstorms will pose a primary threat of large hail and damaging winds.

The unsettled activity will persist into Thursday morning with more showers and thunderstorms possible as the upper-level support for this disturbance rolls through. Winds will pick up out of the northwest to about 20 km/h as skies begin to clear for the afternoon. Temperatures will be a just slightly cooler with a high near 27°C, but the overnight low on Thursday night will be much cooler at around 13°C.

Friday will continue the cooling trend in temperatures as another cold front pushes through, limiting daytime highs to the low 20’s. Mixed skies will be in place alongside a slight chance of some afternoon showers and gusty north to northwesterly winds of 20-30 km/h.

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