Conditions are on the cold and quiet side through early Sunday, with temperatures rising towards the mid 20s by this afternoon. We’ll have some sunshine through the early part of the day, but clouds thicken into the afternoon as we watch a disturbance intensify to our southeast. Expect widespread light snow in the late afternoon with some heavier bursts of snow squalls. As the Super Bowl is wrapping up, winds will shift out of the northwest and usher in cold air, creating a set up for lake effect snow.
Conditions aren’t ideal for a static band of snow. Instead, we’ll likely see the band briefly set up in Oswego County before dropping southward during the morning hours. At first, banding should extend through the Tug Hill during the early morning. Snowfall rates of one to two inches per hour are possible, so visibility may be greatly reduced under the most persistent snow. After sunrise, winds turn a touch more into the northwest and drop lake effect snows farther to the south. Our high resolution computer models suggest that Onondaga and Madison Counties will be included under the snow band as it moves through the morning.
Lake effect snow persists through Monday and into the overnight, before finally breaking up Tuesday morning. Cold air will still be with us as we only reach highs near 20° on Tuesday, but conditions moderate through the end of the week, rising into the mid 30s. Conditions on the weather map will allow for several clipper-style systems to roll through central New York, bringing chances for widespread snow followed by lake effect throughout the week.
