A couple of changes to our lake effect snow as of midday Monday. First, winds have shifted slightly into the northwest and that has caused the band to drift south out of the areas hit hardest this morning. The snow, as of Noon, was close to the Syracuse area. Secondly, the intensity of the snow has come way down. We think part of that can be attributed to loosing our upstream connection to Georgian Bay. At the lake effect's peak this morning. it was that Georgian Bay connection that led to 2 to 3 inch an hour snowfall rates over parts of Oswego and northern Cayuga counties.
The rest of the day, the band of weakened lake effect snow should stay close to the Syracuse area with accumulations of a couple inches or less expected. Closer to Lake Ontario, we think there could still be some additional snow totals greater than 4 inches. This would primarily be over northeast Wayne, northern cayuga and southwest Oswego counties.
Outside of lake effect snow, brisk winds will make a chilly day even feel even colder as wind chill temperatures will be between 0 and +10 all day. Later today and especially tonight winds will decrease allowing for lake effect snow to contract closer to the Lake Ontario shore line. This means while some additional accumulation is possible after 7 pm in the immediate Syracuse area, the greatest threat for new snowfall after 7 pm will likely be northwest of Syracuse and closer to Lake Ontario. In addition, we are watching a weak weather system that will track across Pennsylvania tonight. That system may be close enough to bring a light coating of snow to places like Ithaca, Cortland and Norwich.
We should manage to have a largely dry day tomorrow as high pressure settles over the Adirondacks by early tomorrow morning. It should be noted, where skies clear tonight, temperatures may dip close to or even below zero. It’s unclear if that will occur in the Syracuse area, though it’s more likely northeast and southeast of Syracuse. A separate weather system looks to bring some widespread light snow Tuesday night into Wednesday morning. High pressure looks to bring quiet weather into the region Thursday with yet another system bringing a snow threat Friday.
