After days of spring-like temperatures across Waterloo Region, the coldest air of the season is forecast to arrive next week, bringing a sharp reminder that winter is just around the corner.
The region soared to near 20 C on Thursday, well above the seasonal norm for early November, continuing a stretch of unseasonably warm weather that has defined the latter half of October and the first week of the month.
Waterloo Region is expected to remain mild on Friday, with overcast skies and periods of light rain. Temperatures will hover around 10 C.
Parts of the region could see up to five millimetres of rain on Friday, with scattered showers lingering into Friday night before cooler conditions settle in for the weekend.
Saturday is forecast to bring mostly cloudy skies, a chance of morning showers and a high of 9 C, while Sunday will feature some early sunshine before clouds increase with the possibility of afternoon and evening showers. Highs are expected to remain near 9 C.
But according to CityNews meteorologist Natasha Ramsahai, a brief rebound to around 10 or 11 C is expected on Tuesday, Nov. 10, before a colder air mass sweeps into southern Ontario.
“Here comes the coldest air yet of the season to end off next week and going into the following weekend,” she said.
Winds to pickup next week
Daytime temperatures are forecast to struggle to reach the mid-single digits, while overnight lows will drop to around the freezing mark.
The cold will be made even more noticeable by gusty winds. By Thursday morning, temperatures could dip to around 1 C, with windchill values making it feel between -3 and -7 across parts of the region.
While temperatures are expected to take a dramatic turn, the outlook for Remembrance Day currently remains dry.
The approaching cold snap follows a remarkably mild start to November.
