Tuesday 25 February 2020, 8:30 am – AHEAD DESIGN: Drivers are expected to prepare for poor winter driving conditions with snow accumulating rapidly in southern Ontario on Wednesday.
Splashes of sunshine and temperatures far above seasonal temperatures certainly highlight this week’s spring, but an upcoming system with a far-reaching impact will demonstrate that winter is still alive and well traversed in southern Ontario. Confidence builds up for this late winter storm which has the potential to dump over 20cm into the region until Thursday. More information on the times of this great explosion of snow, as well as a look at the dangerous lake effect that comes back to life shortly thereafter.

TUESDAY: ONLY The appetizer at the “main event”
The splash of wet snow on Tuesday morning abruptly disrupted the spring weather that started the week in southern Ontario. But consider only the appetizer for the main snow event that follows.
As the rain and snow subside, the clouds will mix with some sun peeks expected on Tuesday, with temperatures still hovering slightly above the seasonal mark.
By Tuesday evening, however, light snow will re-develop and continue until Wednesday morning commute.
WEDNESDAY: TEXAS LOW MOVES TO THE LARGE LAKES REGION WITH HEAVY SNOW SNOW
The heavy snowfall on Wednesday comes courtesy of an important Texas Low, which threatens to be at its worst in the afternoon and at night before gradually tapering off on Thursday morning bursts.
“Both morning and evening commuting will be affected, but it is the evening commuting that will be the most challenging as snowfall rates will actually increase during the afternoon hours,” says meteorological network meteorologist Kevin MacKay.
A total of 10-20 cm of snow is expected in most of southern Ontario, with lower snowfall expected for the Niagara region and the northeastern shores of Lake Ontario as the snow will likely change to a rainy mix / snow for part of the evening and overnight.
The total snowfall will increase for the areas north and east, with the heaviest amounts expected in Gray-Bruce county, parts of central and eastern Ontario, including the city of Ottawa where more than 30 cm could fall on Thursday morning.
“Motorists should be prepared for poor winter driving conditions due to poor visibility in heavy snow and rapid snow accumulation,” warns Environment Canada in a special weather report covering southern Ontario.
