    Snowfall Forecast Map

    A strong, Arctic front will push through eastern Canada on Saturday and will initially bring some showers and perhaps a brief, heavy snow squall to many areas during the day as temperatures fall.

    Working from home today and dealing with intermittent internet service. Not good!

    Anyway, as the cold air becomes entrenched the lake-effect machine will get cranking later in the afternoon and continue into Sunday afternoon before winding down.

    It looks like there will be three primary bands of heavier, lake-effect snow off of Lake Huron and Georgian Bay. The strongest band will be the one coming off of southern Lake Huron, which may eventually connect up with Lake Superior by Sunday.

    The London, Ontario area is certainly under the threat for heavy lake-effect snow starting late in the day Saturday and continuing into Sunday, with the heaviest snowfall potentially coming early Sunday morning.

    The snow bands will initially be directed from WNW to ESE then shift to more NW to SE and possibly NNW to SSE for a short time before going back to a more NW to SE orientation.

    The GTA could get an initial burst of snow with the Arctic front during Saturday afternoon. The Georgian Bay lake-effect band could end up getting close to the GTA for a time Saturday evening and at night, so keep that in mind if you plan to venture out on an otherwise windy and unseasonably cold night.

    The Blue Mountains south of Georgian Bay should end up with a decent dump of powdery snow out of this with the Barrie area being near the eastern edge of some heavier snow.

    If you plan to travel later Saturday into Sunday make sure your car is prepared for winter. Travel will be difficult at times in some areas and the wind chills will be close to -15 C.

    By the way, in addition to the natural snow, I would expect much of ski country to take advantage and make snow this weekend with the cold, Arctic air mass in place.
