Evening flurries & squalls followed by AM lake effect

<B>(Sunday Evening February 3, 2013)</B> Light snow showers will be around central New York with snow squalls possible, especially south of Syracuse. Expect that road conditions may rapidly deteriorate as the Super Bowl wraps up.
An upper level disturbance will pass by just to our south tonight, allowing for widespread light snow showers as many are watching the Super Bowl. If you plan on hitting the roads after the game, take caution, since instability in the atmosphere will be at its greatest tonight from 7-11pm. That’s the time period we’re expecting squalls to pass through with spots of reduced visibility and slippery road conditions. As for location, it looks like squalls will mainly be south of Syracuse, such as in the Southern Finger Lakes.
 
Once this disturbance passes, winds shift to allow for a band of lake effect snow to set up. 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.
