After a mix of freezing rain, sleet, and snow that is expected through the day Sunday we will be changing to all snow late. A secondary area of low pressure will form along the East Coast this evening and when the secondary low takes over, cold air will be dragged in from the north and change the wintry mix to all snow and snow will quickly develop across the Twin Tiers. We will be looking at locally heavy snow across some isolated locations. Models continue to suggest a heavy snow band to develop late tonight which could maneuver into the region. We will be watching for areas in Bradford, Tioga(NY), Chemung, Tompkins, and Schuyler county areas for the formation of this band. Where this band forms and lingers, we could see snow totals upwards of 15 inches. Generally speaking, for those counties, we are expecting snowfall totals of 5"-10" and for Steuben and Tioga (PA) 3"-6", and Potter county should expect 1"-3" all through Tuesday morning.

Snow will continue through the Monday morning commute across the region and linger into the afternoon before tapering by the Monday night. This will cause slippery travel as temperatures will be at or below freezing so snow will be sticking to the roadways.
