UPDATE: The heat is on as summer arrives in Sarnia-Lambton
The heat is on as the summer of 2020 officially begins.
The forecast for the arrival of summer Saturday calls for sunny skies with a high of 32 C, 90 F, and a humidex of 38.
Environment Canada issued a heat warning for Sarnia-Lambton on Friday. The heat warning for the area ended on Sunday night.
The weather agency also issued a special air quality statement on Saturday warning of elevated pollution levels. However, the statement ended just before 9 p.m. Saturday night.
The summer solstice is Saturday, June 20 at 5:44 p.m.
It occurs in the Northern Hemisphere when the sun reaches its highest and northernmost points in the sky.
The first day of summer is the longest day and shortest night of the calendar year.
Environment Canada meteorologist Gerald Cheng said long-term models suggest the average temperature will be above normal for much of the season.
“If we look at the three months as a whole, June, July and August or even July, August, September, it looks to be slightly above normal,” said Cheng. “But we have to be careful and see how the next four weeks will turn out, if we can verify what we’re seeing.”
Cheng said precipitation over the season is expected to be normal but that’s difficult to predict because it’s thunderstorm season.
“And with thunderstorms, they’re usually isolated, and so your neighbour could get a lot of rain and you might get just a little. Thunderstorms are very hit-and-miss and some areas are going to get a lot and some areas are not going to get enough,” he said.
