Winds aloft will stay out of the northwest this evening which mean lake effect snow showers will continue the first half of the night. There could be a coating to a couple of inches of new snow before our winds go light overnight and whatever is left of the lake effect retreats back to the Lake Ontario shoreline.
A nice little break tomorrow for people with last minute Christmas shopping or holiday travel plans. A weak area of high pressure will manage to cause at least some breaks in the clouds at times tomorrow as our temperatures rise to near normal levels during the afternoon. This break from the snow, however, will be short.
By later tomorrow, low pressure will be tracking northeast across Ohio. This won’t be a powerful low pressure system like we saw last Friday/Saturday, however, it will be strong enough and have enough moisture to cause a widespread shield of snow to the north of its track. With this low going just to our south Christmas Eve we expect a widespread light to moderate snowfall for all of central New York. . We think the snow will fall into Christmas day morning before low pressure pulls away, accumulating an additional 1-3” by the time the kids wake up.
A more substantial storm could impact us for the middle of the week. Right now, the storm is on the weather map moving into the West Coast. It will track through the middle of the country over the next few days and by Wednesday it will take a turn to the northeast. This system will have plenty of moisture to work with but there are some questions as to how warm the lower atmosphere might get over us potentially causing a mix of precipitation here in central New York. If you have any travel plans in the Northeast or Mid Atlantic states midweek you’ll want to keep close tabs are where this storm is headed and stay tuned for more updates.
