THURSDAY: SNOW EASES OFF IN THE NORTH, SOUTH COULD SEE PASSING SHOWERS
Most of the heavy snow in the north has moved out, with only 1-2 cm left to fall in areas close to the Quebec border Thursday morning before it exits Ontario by afternoon.
The same cold front will spread some brief, passing showers across southern Ontario through the afternoon. Not much will accumulate, with the heaviest amounts limited to 5 mm or less in the southwest and parts of central Ontario. Areas to the north, Sudbury and eastward to the Quebec border may get 5-10 mm of rain through Thursday.
Temperatures will hit the double digits in parts of southern Ontario Thursday, reaching daytime highs above seasonal for this time of the year. The GTA is typically around 7°C for this time of year.
A stateside low tracking through Ohio and New York state will spread the northern edge of showers to extreme southwestern Ontario through Thursday overnight. The relatively mild conditions will be short-lived as temperatures will drop back to seasonal Friday, conditions will be dry.
WEEKEND: COLORADO LOW MOVES IN
A Colorado low will move into Ontario this weekend bringing rain, mild temperatures and the risk for thunderstorms across the south. A swath of accumulating snow is expected to spread across northern Ontario through Sunday.
While there is still some uncertainty with timing, rain may arrive in southern Ontario Saturday afternoon. The risk for thunderstorms will occur overnight into Sunday morning. Gusty winds will also accompany this system across the province.
"If we see a break in the rain showers Sunday, temperatures will likely climb into the mid-upper teens for southern Ontario," Weather Network meteorologist Kelly Sonnenburg says.
