It will be a very hot and humid day in southern Manitoba today. It may be the hottest day of the year so far. Temperatures are expected to rise into the low to mid thirties, and with the humidity it will feel into the low to mid forties.
It is one of those days when strenuous activities outdoors should be reduced or taken indoors. If you have to be outside, stay hydrated and try to stay in the shade as much as possible to avoid heat exhaustion.
All this humidity, along with an approaching trough will offer the opportunity for severe thunderstorms in Manitoba later this afternoon and evening. The best chance for these storms will be in the Interlake and eastern Manitoba. Capping in the atmosphere may prevent storms from forming altogether south of these areas, where the cap is strongest. The main threats today will be large hail, damaging winds and flooding rains. Tornadoes are possible, however conditions for their formation are not as favourable as they were in Saskatchewan yesterday.
