It's going to be another hot one before cooling off.
Environment Canada this morning issued a heat warning for Stratford and most of southern Ontario.
A hot and humid airmass is expected to affect portions of Southwestern Ontario and the Golden Horseshoe today (Friday, Sept. 5). High temperatures near 30 degrees and humidex values near 40 are forecast for this afternoon.
Some relief is coming however. A cold front will sweep across the area this evening bringing a return to near seasonal temperatures for the weekend.
