Ontario: Cool, rainy weekend, HEAT returns for Canada Day
Saturday, June 23, 2018, 12:48 PM - Summer has officially arrived, though the first weekend of the season is actually feeling more like spring, especially with an unsettled and showery weekend ahead.
If you can shake this less-than-ideal first summer weekend however, the return of the heat coincides perfectly with Canada Day next week. In fact, that long weekend could be the start of the hottest trend of the summer. Time to book some last minute vacation? More on that, below.

- Temperatures quickly recover next week with a warming trend heading into the Canada Day weekend
WATCH BELOW: HOW THE RAIN PLAYS OUT OVER THE WEEKEND
UMBRELLA WEATHER: SUNSHINE A MISS FOR FIRST WEEKEND OF SUMMER
Periods of rain will persist through the weekend, with widespread showers beginning Saturday morning for southwestern Ontario.
"The GTA and much of southern and central Ontario will dry out through the afternoon and remain so into tonight, although the cloud will be holding strong," Weather Network meteorologist Kevin MacKay says. "Rain will continue into the afternoon for Ottawa."
Environment Canada issued a rainfall warning for the Windsor area early Saturday afternoon, warning of local amounts of 50-70 mm.
MacKay says a trough will hold over the lower Great Lakes for Sunday, bringing a wetter afternoon to the GTA, Huron shores, and into the Kawarthas.
By the time the region dries out, some 10-20 mm is expected to have fallen for the Golden Horseshoe, with lesser amounts north of Lake Simcoe and higher local amounts for Windsor due to potential thunderstorms later Saturday.
JULY LONG WEEKEND KICKS OFF POTENTIAL HEAT WAVE
Temperatures quickly recover to near seasonal values by mid-week next week with a warming trend expected to continue into the weekend.
"An extended period of very warm to hot weather is expected across our region in time for the Canada Day long weekend and continuing for through the first week of July," Gillham says. "It is too early to know the weather details for any specific day, (and whether we will have storms to go along with the heat) but overall it looks like a classic warm/hot weather pattern will dominate this time period."
According to Gillham, this could turn out to be "our most extended heat wave of the summer."
