A much-needed warm-up heads to southern Ontario, but there’s a catch

Look out for slick roads through Sunday morning in southern Ontario.

Are you ready for a bit of relief behind this system? Sunday will bring about a mild break from the snowy pattern that’s been draped over southern Ontario.

Looking ahead: Milder air, then more cold arrives

That clipper system will help drag warmer air north of the border, lending southern Ontario a few days of milder temperatures before we take a dip again next week.

Readings are expected to climb well above freezing on Sunday. We’re likely going to see some rain showers on Monday, but some light freezing rain and mixed precipitation are expected north and northeast of Toronto.

DON’T MISS: Canada hit with winter weather already, but will it stay for December?

Another system expected to develop over the U.S. Midwest on Tuesday will track into southern Ontario with widespread rain Tuesday night. There’s also the potential for snow for some areas well to the west of the storm track as a cold front approaches the region.

A strong cold front is expected to track across the region on Wednesday, followed by a quick shot of Arctic air with temperatures a few degrees colder than seasonal. This should trigger another round of significant lake-effect snow by Wednesday night.

Much milder weather is expected to arrive for the weekend, with that warmer pattern dominating into mid-December. We’ll be watching the potential for a colder pattern to kick in during late December and early January.
