A high of - 4 C was expected in Toronto Sunday. The best chance for periods of steady and even moderate snow will be between 10 PM Sunday and 3 AM Monday.
Before that takes effect, an inch or two of snow is expected Sunday evening into Monday morning.
Considering the city's last snowstorm had colleges and universities shutting down, flights cancelled, and people literally skiing through downtown streets, you should probably prepare for your life to be slightly delayed, interrupted, or completely inconvenienced between Tuesday and Wednesday of this week.
Thursday: Mostly sunny and a tad cooler.
As it moved it, the storm obscured Seattle's famous Space Needle from sight. The biggest snowfall totals will likely be into Mifflin and Juniata counties where 6"+ is possible". Snow and ice pellets are expected to arrive late Monday night. The upper levels of the atmosphere will be warming, but temperatures at the surface will still be below freezing. Depending on how quickly we can climb back above the freezing mark, that will depict how much ice we can see. It could then turn into ice pellets and freezing rain and continue to fall for a few hours. Warmer air will surge into the region late Tuesday.
"Strong and gusty easterly winds may cause low visibility in blowing snow before the snow changes over to freezing precipitation", Environment Canada said.
