It is a hot and humid, but otherwise uneventful weather kind of day across Manitoba. Uneventful in so much as there's little chance of convection, or thunderstorms across the province.
That said, heat warnings are in effect for central/northern regions including Flin Flon, The Pas, Norway House and Island Lake. Look for hot highs today and on Friday around 30C and warm overnight lows in the upper teens. A cold front will bring you some relief by the weekend.
Temperatures will be similar in the south, in the upper 20s/low 30s, but that's not quite enough to trigger heat warnings here. Still, take precautions in this heat and humdity. Humidex values make it feel in the mid-30 today. And tonight will be very warm and mostly clear.
Friday is potentially a different story. It will be just as hot in the south. But an approaching cold front should reach the Saskatchewan/Manitoba border by the afternoon. It could trigger thunderstorms. But they could also form in the wam sector ahead of the front. If that happens, there is the risk of susbtantial rainfall. If thunderstorms form closer to the cold front, watch out for damaging hail and winds.
If a line of thunderstorms does develop, they could last from Friday afternoon into the night.
