Environment Canada is telling Southwestern Ontario residents to enjoy the heat while it lasts because it won’t last long.
Meteorologist Geoff Coulson said a low-pressure system should move into the region this weekend, bringing more seasonal daytime highs.
Before that happens, Coulson said it’s possible records could fall over the next day or two as daytime highs reach the mid-20s on Wednesday, Thursday, and Friday.
Windsor anticipates 29 degrees Celcius on Thursday. The record, set in 1941, is 29.4 C.
“Even for today [Wednesday], the forecast high is 27 C. The current record is 28.1 C set back in 1977, so not too far off,” said Coulson. “Tomorrow, getting even closer to the record.”
Sarnia residents can expect a high of 28 C, smashing a record of 22.8 C set in 2006.
Records could fall in Chatham-Kent and Wingham too. Chatham-Kent’s expected high on Thursday is 26 C, far above the 17.6 C set last year. It’ll reach 24 C in Wingham, beating the 2015 record of 20.5 C. London will also get very close to the previous record of 28.9 C with a high of 28 C.
“I think what’s even more interesting this particular weather event is just the length of time we’re going to be dealing with these much-above-normal temperatures,” added Coulson. “This is expected to continue right into Friday. Low-20s for Saturday, and then we finally start to see more seasonal temperatures for Sunday and into next week.”
Coulson said while the heat may be unusual, the system bringing it to us is actually common.
“This is an area of high pressure that often forms in the Atlantic [Ocean] off the Carolina coast or the Bermuda area. When it strengthens — what we’re getting is a very strong flow coming up from the American deep south,” he explained.
Not only should we expect a cool down in the second half of April, Coulson predicts near, or even below, seasonal rainfall.
