More wintery weather tonight.
The calendar may read that it’s the first day of spring, but it’s no surprise that mother nature is still in a wintery mood. A potent disturbance currently over Minnesota is expected to carve a path across Southern Ontario tonight with the centre of low pressure likely to cross the Toronto area after midnight.
It will deliver a relatively brief but rather intense period of precipitation to many areas of Southern Ontario, including snow, freezing rain and some rain.
Although some uncertainty remains with the track of the low, current indications suggest that for most regions extending from Southern Lake Huron to the Golden Horseshoe precipitation would begin tonight as snow or freezing rain and could be mixed with ice pellets at times as well. The exception is from Sarnia-Lambton to areas along the north shore of Lake Erie where rain is most likely, with a risk of freezing rain. Freezing rain warnings will be issued shortly for a swath from Southern Lake Huron through the Golden Horseshoe.
To the north, from Grey-Bruce through the Kawarthas to Brockville, a significant heavy snowfall is becoming likely and warnings will be issued shortly. This area of snow will begin this evening near the Lake Huron shoreline and reach the Ottawa Valley and Cornwall areas overnight. General snowfall amounts in excess of 15 cm are expected in the warnings areas from Northern Lake Huron eastwards through Barrie and Newmarket through Peterborough to Brockville. Snowfall amounts of 5 to 10 cm are expected to the north and south of this swath.
Environment Canada meteorologists continue to watch the Progress of this low system closely.
The public is advised to monitor future forecasts and warnings as warnings may be required or extended.
