Environment Canada has issued a yellow heat warning for Windsor-Essex. The national weather service is forecasting daytime highs of 29 to 31 C, overnight lows of 20 to 22 C, and humidex values near 38 through Wednesday, and could persist into Thursday. Severe Weather Meteorologist Rob Kuhn says a warm front and a southwesterly flow around a large high-pressure system are pushing hot, humid air into the region. “The next few days the afternoon temperatures are going to be in the low 30s, nighttime temperatures in the low to maybe even mid 20s, and peak humidex values getting close to 40 on the most humid days,” Kuhn said. He says the hottest conditions will continue for the next few days before relief arrives later in the week. “At this point it looks like the temperatures are going to be in the low 30s through Wednesday,” he said. “We’re looking at a high of 32 on Wednesday and then Thursday a week cold front goes through and it drops at temperatures, not much, but the afternoon temperatures on Thursday will be in the upper 20s.” Kuhn says while the calendar is about to turn, summer-like temperatures are expected to stick around. “It’s important to note that September has become pretty well a summer month now. It’s been like that consistently since the late 1990s. Almost every year it’s been more summer than fall. This one is seems to be starting out as well, no exception. The next couple of weeks look to be warmer than the long term average,” he said. The Windsor-Essex County Health Unit (WECHU) also issued a heat warning through Wednesday. The health unit says dizziness, headaches, nausea, weakness and confusion can be signs of a heat-related illness. Anyone experiencing these symptoms should seek immediate medical attention.
