WEEKEND WEATHER FORECAST

Early Edition

This coming weekend will be influenced by an influx of colder air and a dip in the jet stream to form an upper air trough, pushing a cold front through. The disturbances rotating around an upper low will bring showers on Saturday.

GEFS upper air wind forecast (250 mb- jet stream level) for Saturday 8 PM. The dip in the jet winds and the upper air low in upper NY State will bring enough moisture and lift to create cloudiness and light showers on Saturday. The tropical jet (2) is just visible.
