It’s been feeling more like summer than fall in Toronto to kick off the first work week of October, with sunny skies and high humidity taking hold before a cold front arrives ahead of Thanksgiving.
Record-breaking warmth is expected on Tuesday in what should be the warmest day of this rare fall heat wave.
“The warm weather continues to dominate the forecast in Southern Ontario,” says CityNews 680 meteorologist Denise Andreacchi, saying some areas north of Toronto could actually reach 30 C. “It is definitely an outstanding weather trend that we are in the midst of.”
“It’s shorts and t-shirt weather for the next couple of days.”
Monday in Toronto saw sun and cloud with a high of 26 C and a humidex near 30. The temperature only dropped down to 16 C overnight, which is actually just slightly cooler than the average daytime high for this time of year.
Tuesday should be the warmest day this week and we could see 22-year-old heat record broken — it will be sunny with a high near 28 C and a humidex in the low 30s. The previous record at Toronto Pearson for Oct. 3 was 27.1 C set in 2001.
Things will be slightly cooler Wednesday with an expected high near 24 C. The Oct. 4 record of 27.2 C was set in 1951. Thursday will be cloudy and windy with a high again near 24 C.
Friday could see some showers with a high near 19 C, and then things will cool down even more over the Thanksgiving long weekend with daytime temperatures in the low teens.
“By the weekend we are unsettled and much, much cooler weather starts to take over,” says Andreacchi. “It’s this weekend when we start to feel that crisp fall air.”
The above seasonal temperatures for the first week of October follow a warmer than usual weekend in the GTA. Sunday saw a high of 27 C in Toronto.
The Weather Network’s fall forecast predicted a “fickle fall” this year as the season is forecast to be chilly early on for most of Canada before above normal temperatures lead the country into winter
Ontario is expected to see a nasty push of cold air in October but winter is forecast to begin on a mild note. The forecast suggests the province will see less precipitation than normal, but there may be some wind storms during the fall that cause power outages.
