Snow showers possible tonight

Some slightly cooler air is poised to move into central New York and will impact our weather tonight and tomorrow.  The leading edge to the cooler air is a cold front that will move from north to south through the region tonight.  As the front moves through, there will be a wind shift from the southwest to the northwest.  This means any lake effect snow that starts tonight east of Lake Ontario will drop south and weaken overnight.  What is left of the lake effect snow will move through Syracuse at or just before sunrise tomorrow.  Accumulations will be light in Syracuse (an inch or less) but there could be several inches up over the Tug Hill.

Our temperatures will be slightly cooler in the wake of tonight’s cold front. In fact, as the colder air moves in during the afternoon our temperatures may drop slightly after reaching the high of 30 in the morning.  This cooler air will also be drier so that will mean some sunshine in the afternoon.

A weak weather system will move through the area Sunday with another round of snow showers or even steadier light snow possible. With temperatures rising above freezing during the day Sunday we expect any accumulation of snow to be on the light side. After that, high pressure will build in from the west and our weather will become quiet early next week.  There is some debate as to whether or not a brief shot of cold air will move in Sunday night and Monday.  So be aware, upcoming forecast may change.

It still seems to be a good bet that we will warm up toward the middle of the week but the real question is how quickly moisture (and rain) returns to Central New York and the Northeast.  The battle lines are still drawn between our computer models as to whether Wednesday or Thursday will be the arrival date of some rain. The most consistency is coming from the model forecasting a dry Wednesday with showers returning for later in the week. We’ll keep you posted if there are any changes.
