Humidex Values near 40C Tuesday

High heat and humidity warnings are in effect for most of Ontario and southwest Quebec for Tuesday and Wednesday. A very muggy air mass from the US will invade the area. Temperatures will soar into the mid 30's with Humidex values approaching 40-45C. Drink plenty of fluids and limit outdoor activities. The very young and old are at particular risk as well as those living in large urban areas.

Thunderstorms will cool us off late Wednesday.
