Cool & Unsettled Weekend; Heat Builds for Long Weekend

Spring-like Weather for First Weekend of Summer

Rain will spread across the region this morning (thunderstorm is possible). Some clearing is expected during the late afternoon and evening. Temperatures will once again be on the cool side of seasonal on Sunday with highs only in the upper teens and lower 20s.

Warming Trend Next Week

Sunshine will return for the start of next week. Temperatures will continue to be on the cool side of seasonal on Monday despite the full sunshine.

However, we will gain a couple of degrees on Tuesday and the heat and humidity will increase on Wednesday. A period of rain and thunderstorms is likely Tuesday night and into Wednesday with the potential for strong storms (especially to our east). 

Hot weather is expected for Thursday and Friday of next week with highs in the upper 20s to lower 30s.

Heat Returns for the Long Weekend & Early July

An extended period of hot weather is expected across our region for the Canada Day long weekend and continuing through the first week of July. It is too early to know the weather details for any specific day (such as the timing of any thunderstorms to go along with the heat) but overall it looks like a classic hot weather pattern will dominate this time period. This will likely turn out to be our most extended heat wave of the summer.
