8:18pm bitterly cold air temperatures along with strong and gusty winds are making it feel like an ice box across the Northeast. A storm system that impacted the region with milder temperatures and heavy rain this weekend has pulled away; in the wake of this storm system the coldest air mass since last January has infiltrated the Northeast, enough instability will be present to produce some light snow along the coast through early afternoon on Tuesday. Temperatures are running between 15 and 20 degrees below normal for this time of the year. The cold and wind over the relatively warmer waters of the Great Lakes are producing Lake Effect Snow over western New York State, western Pennsylvania and northeastern Ohio. Winter weather watches and warnings for Lake Effect Snow are in effect for most locations down wind of the lakes. A Lake Effect Snow warning is in effect for Buffalo until 6am Wednesday morning, between 10 and 16 inches of snow is expected with higher amounts south of Buffalo as well as regions down wind of Lake Ontario from Rochester to Syracuse where up to 3 feet of snow is possible. Lake Effect Snow will continue through Wednesday producing localized blizzard conditions along the New York State Thruway from Buffalo to Syracuse. The Lake Effect Snow should come to an end by Thursday and a period of tranquil weather will prevail through the upcoming weekend. Computer models are indicating that on Sunday December 19th a low pressure system could develop a long the Northeast coast. Depending on the cyclone genesis of this potential system, we could be dealing with a Nor'easter for the big cities of the Northeast from Washington to New York and Boston.
