Winnipeg will see another hot and humid day capped off with a risk of thunderstorms before cooler temperatures move in.
Temperatures will again climb into the low 30s today in Winnipeg as southerly winds continue to pump heat northwards. The city has seen a bit of a break from the humidity overnight, but it will build back in through the day with dew points rising to around 20°C. A disturbance lifting northwards into the region this morning will bring a chance of showers later this morning into the afternoon. By late afteroon, activity will intensify with thunderstorms developing along a cold front pushing eastwards across the province.
Much of the Red River Valley and areas east will see a risk of severe thunderstorms this evening, but the greatest threat will be over southeastern Manitoba. The main threats in the Red River Valley will be large hail and damaging wind gusts. The thunderstorms should move eastwards out of the Red River Valley through the evening. Brisk southerly winds of 30 to 40 km/h today will ease in the evening.
