Cooler day today behind yesterday's cold front. We'll likely only reach about 25-26°C under a mix of sun and cloud and a light westerly breeze.
A trough of low pressure moves in tonight and could bring some showers and thunderstorms throughout southern Manitoba. Best risk appears to be in the Parklands, Interlake and east of Lake Winnipeg. However, a few storms are still possible further south, including in Winnipeg. Severe potential looks small. Will provide some updates in the comments below later today if needed.
Skies clear tomorrow morning, giving way to a hot and sunny day. Assuming there isn't any unexpected haze, we should manage to reach 31-33°C. Humidex values will likely push the mid to high 30's, particularly in southeastern Manitoba.
Next chance for rain will be Monday night. However, models are not agreeing on how far north the risk will reach. Thunderstorm risk for the event looks to remain mainly to our south in the US.
