Here is my initial snowfall forecast for the storm which will impact parts of eastern Canada starting late tonight and through Friday evening.
The GFS/ECMWF models are fairly similar with the track and intensity of the storm, putting areas just north of London and Toronto in the heaviest snowfall, while the NAM continues to show a stronger, slightly farther south storm which would put London and the Greater Toronto area in the heart of the heavy snow with at least 20 cm. Right now, will lean with the GFS/ECMWF combo with consideration of the NAM.
Roads will be slippery Friday morning from London to Kitchener and the GTA as the snow begins before dawn, which allows it to get a head start accumulating on the roads at this time of year. Much of the snow from Ottawa to Montreal will start during the middle of the day, which will cut down on the road accumulation due to the higher angle of the Feb. sun.
Obviously this will be the biggest snowfall of the season for many.
The storm should be all snow north of the dashed red line.
