Many consider the Labour Day weekend to be the last days of summer, but the forecast disagrees.
Environment Canada has issued a heat warning for several parts of northern Ontario, including our area.
From Sunday to Tuesday, temperatures are forecast to be in the high 20s or low 30s, with humidex values ranging from 35 to 40 degrees.
“Despite overnight temperatures being lower than warning criteria in some areas, humidex and daytime highs will be very atypical of early September,” said Environment Canada.
“The passage of a cold front will bring an end to the heat on Tuesday and Wednesday for some areas.”
