Manitoba weather: Warnings and watches galore

Colleen Bready has your current conditions and updated weather forecast for July 4, 2025.

With Friday’s mix of atmospheric conditions, it would almost be easier to share which Environment and Climate Change Canada (ECCC) weather alerts are not in effect.

High heat and humidity continue in southern Manitoba and northwestern Ontario, while wildfire smoke plagues northern Manitoba.

Environment and Climate Change (ECCC) issued a tornado watch for a large section of northwestern Ontario, including Lake of the Woods, Dryden and Fort Frances.

The weather agency said severe thunderstorms could develop there Friday that could produce tornadoes. Heavy rainfall, strong wind gusts and sizeable hail are also possible. Neighbouring regions, including Kenora, are under a severe thunderstorm watch.

A heat warning remains in effect for Winnipeg, southeastern Manitoba and northwestern Ontario for one last day on Friday. A cold front passing Friday night will bring relief and cooler temperatures in the low to mid 20s by Saturday.

Until then, thunderstorms can’t be ruled out late Friday afternoon or early evening in Winnipeg and much of the south.

Meanwhile, northeastern Manitoba is under an unusual severe thunderstorm watch Friday. ECCC said thunderstorms that developed there this morning will move through the region into northern Ontario by Friday evening.

Most central and northern regions are also under an air quality warning or special air quality statement Friday. The weather agency said smoke moving through the region should improve Friday night.
