Snowfall warning for
City of Toronto upgraded from winter storm watch
10 to 15 cm of heavy snow..Mixed with ice pellets..Overnight and Monday.
The lead disturbance that brought a few mm of freezing rain and ice pellets to areas near Lake Erie and 2-4 cm of snow from Sarnia through Kitchener to the Toronto area has moved away into upstate New York. Isolated flurries or very brief occurrences of freezing drizzle are possible during this expected break in the weather under generally overcast skies into this evening.
Despite the lull..The battle between the mild air well to the south and the invading cold Arctic air of winter from the north is not over. The main storm centre..Currently developing over northeast Texas will ride northeast along the line of a stalled front into Ohio and Pennsylvania by Monday. This low pressure will be quite a bit stronger than the previous one and will spread a larger area of snow and freezing rain back into the district beginning later this evening over southwestern Ontario then into remaining regions overnight.
Freezing rain and ice pellets will once again affect areas near Lake Erie where the freezing rain warning remains in effect. Ice accretions of a few mm are quite possible by Monday.
Snow..Heavy at times..Mixed at times with ice pellets and freezing rain will affect a swath of regions from Sarnia through London to Hamilton and St Catharines where winter storm warnings remain in effect. Snow and ice pellets amounts of 10 cm are quite possible along with ice accretions of 2-5 mm during periods of freezing rain.
Further north in the Kitchener to Toronto to Kingston areas..Snow and ice pellets will become heavy at times overnight and Monday morning and may mix at times with freezing rain as well. Snow and ice pellet amounts of 10 to 15 cm appear quite likely by Monday evening. Snowfall warnings are in effect for these districts.
The snow will spread northeast into the St Lawrence Valley Monday morning where the winter storm watch may be upgraded to warnings later today as the event draws closer.
Should the heavy snow or freezing rain push further north than expected..Warnings will be adjusted accordingly.
This may be quite a high impact storm as most areas have had little or no snow or freezing rain until now. Motorists should exercise extreme caution and be prepared to allow much extra time to reach their destination if travel is absolutely necessary. Dangerous winter driving conditions are likely..Especially during the Monday morning hours when the snow and freezing rain may be heaviest across a large part of the forecast district.
Winter will finally win this latest battle with the mild air as the storm centre races off into New England by Monday evening. In its wake the coldest airmass so far this season will invade behind this storm by Tuesday. Temperatures will plunge several degrees below normal as winter finally settles in for the time being.
Environment Canada continues to monitor the development of this situation closely.
