It will be another hot one for Manitoba today as temperatures rise into the low thirties, and dewpoints in the high teens and near twenty. This will bring humidex values close to 40 later this afternoon and early evening if you are not under a thunderstorm. It will be one of those days where strenuous activities outdoors should be reduced, and everyone should keep hydrated outdoors. Seeking shade if you have to be outdoors is a great idea.
Today will also be a watch-the-sky type of day as severe thunderstorms will be possible throughout southern and central Manitoba this afternoon and evening. Severe thunderstorm watches have already been issued by Environment Canada this morning for all of southern Manitoba, excluding only the Virden and Melita areas. Large hail and damaging winds will be possible. A small risk of tornadoes exists in the Interlake due to lake-breeze convergence, and in south-central/southwestern Manitoba. Winnipeg's best risk for storms will be late afternoon and evening.
Behind these storms, it will be a cooler and drier day tomorrow with highs in the high twenties, and humidity low.
Things heat up again Tuesday. Highs in the low to mid thirties will be possible, however it will be a drier heat. Humidex values are ''only'' expected to be in the mid to high thirties.
