Special weather statement in effect for the area: Potential for heavy thunderstorms today followed by an extreme heat event for the Canada Day long weekend.
The scattered showers and isolated thunderstorms forecast today will give way to a persistent southwest flow, bringing hot and humid air from the Gulf of Mexico to Southern Ontario. Beginning Friday or Saturday and continuing through the Canada Day long weekend, expected daytime highs are in the low to mid thirties with humidex values into the mid forties. Overnight low temperatures will only fall to the low twenties, providing little or no relief from the heat.
There is still uncertainty regarding when the heat event will come to an end. Current indications suggest the heat could persist into the middle of next week.
This will likely be the most significant heat event of the season thus far. Heat warnings will be issued as the event draws nearer.
Weather for next few days:
Today Showers with risk of a thunderstorm. Local amount 10 to 15 mm. High 20. Humidex 27. UV index 4 or moderate.
Tonight Showers with risk of a thunderstorm. Local amount 10 mm. Low 18.
Tmrw A mix of sun and cloud. 30 percent chance of showers early in the morning. High 27. Humidex 32. UV index 9 or very high.
