warning BLACK ICE TONIGHT AND LIGHT SNOW LATE TONIGHT THROUGH WEDNESDAY MORNING
Special Weather Statement issued February 24 at 7:01PM EST by NWS Upton NY (Region Impacted: Northern Fairfield; Northern New Haven; Northern Middlesex; Northern New London; Southern Fairfield; Southern New Haven; Southern Middlesex; Southern New London; Western Passaic; Eastern Passaic; Hudson; Western Bergen; Eastern Bergen; Western Essex; Eastern Essex; Western Union; Eastern Union; Orange; Putnam; Rockland; Northern Westchester; Southern Westchester; New York (Manhattan); Bronx; Richmond (Staten Is.); Kings (Brooklyn); Northwest Suffolk; Northeast Suffolk; Southwest Suffolk; Southeast Suffolk; Northern Queens; Northern Nassau; Southern Queens; Southern Nassau)
With temperatures below freezing across the region any snowmelt that occurred during the day will refreeze, especially on untreated surfaces, resulting in black ice. Then a period of light snow is likely by late tonight into the Wednesday morning commute, 400 AM to 1000 AM EST. This light snow, 1 to 2 inches, falling on top of the black ice could make for treacherous travel. Rain may also mix in with the snow along the coast early Wednesday morning. Motorists should be prepared for the possibility of a period of snow covered roads during the morning commute. Temperatures will be rising above freezing during the morning from south to north.
