An Arctic cold front will pass through the region this afternoon.  A narrow line of snow squalls will move west to east ahead of this boundary, which will allow for brief, whiteout conditions and slippery travel conditions.  Although total snow amounts won't be high today,  very low visibility and gusty winds may accompany any snow squall making for hazardous travel. 

Strong gusty winds will develop this afternoon, lasting into this evening. Westerly winds of 15 to 25 mph with gusts up to 50 mph may bring down large tree limbs and some trees. A Wind Advisory has been issued for the Mohawk and Schoharie Valleys, Capital District, eastern Catskills, mid Hudson Valley, Taconics, Berkshires, Litchfield Hills, and southern Vermont.

Behind the front, a bitterly cold air mass will move into the region for late today and persist through Friday. The combination of the cold temperatures and winds will produce dangerously low wind chill values, especially tonight through Thursday morning. Wind Chill Values will reach as low as 15 to 35 below zero.  Wind Chill Advisories and Wind Chill Warnings are in effect for the entire region for late today through Thursday morning.  

In addition, heavy lake effect snowfall is expected for the western Adirondacks tonight through Thursday night. Winter Storm Warning is in effect for northern Herkimer County & Winter Weather Advisory is in effect for Hamilton County for late today through Thursday night. Up to 15 inches of snow is possible in extreme northern Herkimer County.
