Ontario: Messy system will likely impact back-to-work commute

Extensive weather advisories have been issued ahead of the low pressure system that is tracking into southern Ontario.

MESSY WEATHER BEGINS MONDAY NIGHT AND WILL LIKELY IMPACT TUESDAY COMMUTE

A messy low will track through the Great Lakes region Monday night and will continue through Tuesday morning. Snow will begin in the southwest late Monday evening and will reach the GTA in the overnight hours.

The precipitation will start off as snow for the GTA before transitioning to a rain/snow mix and then showers Tuesday morning, in time for the morning commute, so travel times will be affected. It will ease off by noon hour in the south as the system tracks through eastern Ontario and southern Quebec.

A very short period of freezing rain is possible when snow switches to rain through the GTA early Tuesday morning and late morning and early afternoon for eastern Ontario.

Snowfall amounts in the GTA will be limited because of the quick changeover to a rain/snow mix and then showers. Northern parts of the GTA could see 5-10 cm of snow but areas along Lake Ontario shorelines will see amounts in the 2-5 cm range before the transition to rain occurs.

Weather advisories are in place across the GTA including Hamilton, Toronto, and York - Durham that warn of the snowfall and the potential for poor winter driving conditions with low visibility at times. The morning commute could be impacted by these adverse conditions and it is recommended that motorists leave extra time to reach their destination.

Weather advisories are also in place across Muskoka, Algonquin, and the Ottawa region that warn of the incoming snow and say motorists should be prepared for poor driving conditions. The City of Ottawa could get close to 10 cm of snow while regions surrounding Kingston, Sudbury and Parry Sound will see between 10 to 15 cm through Tuesday afternoon.

"After a mild afternoon, colder weather will return Tuesday night and into Wednesday and any standing water or leftover slush will turn to ice," says Weather Network meteorologist Dr. Doug Gillham, adding another quick shot of cold air from the Arctic will usher into the region by mid-week. Temperatures will be well below seasonal for Wednesday and Thursday.

MILD WEATHER DOMINATES SECOND HALF OF THE MONTH

Although parts of next week will feature more cold air from the Arctic, overall there's no consistent cold weather in sight for the rest of February.

"Mild Pacific air is expected to return by the end of the week with above seasonal temperatures likely for next weekend and into the following week," Gillham says.
