The problem with these bands of snow is that they can be very narrow, which makes them hard to forecast, because a slight change in the wind direction can mean a big deal in terms of snowfall amounts.
By Wednesday evening, the winds will begin to shift to a more westerly direction, allowing for the plume of lake-effect snow to be directed to areas east of Lake Erie in Lake Ontario.
According to the warning for Almaguin, issued at 8:25 p.m. Tuesday, Dec. 5, and updated at 3:14 p.m. on Wednesday, snow squalls are expected.
Total accumulations through late this week could be 1 to 2 feet in areas that see the most persistent bands of snow east and southeast of Lake Erie and Lake Ontario.
For the weekend, Saturday looks to have a mix of lake enhanced snow up north and a weak clipper like system moving through as well.
A shot of colder air will cross Lake Michigan Wednesday night and Thursday morning, causing lake effect snow to develop. This is just a cold pattern, and the cold is leading to better chances of light snow. We should be closer to normal on Monday.
Additional Eastern Snow Chances Ahead?
We're not entirely on the sideline from snow here.
The weekend should start quiet with clouds increasing Saturday in advance of a cold front which is slated to move through Saturday night with some snow showers and flurries. The action is gone rather quickly, and we should see sunshine and cold air again for next Friday. Temps will be the key...if we stay cold this would be the first good snow system for the state. In fact, if the current moisture projections hold, we could see several inches in spots from I-70 northward next week. The northern half of the state sees better snow chances in our forecast this morning.
