Icy mix to rain
Snow showers will transition to a mix this evening as temperatures slowly warm. South winds are driving moist air up and over the cold air that is sitting right on top of the Twin Tiers. Temperatures will first warm to the freezing/melting point above the layer of colder air near the surface. As liquid drops fall into the colder air near ground level, they will first freeze into sleet pellets in the late afternoon and early this evening. The warming south winds continue to blow as the evening progresses, and the layer of colder air near the ground will slowly become shallower and shallower. By the middle of the evening, that cold air near the surface should be too shallow to freeze the falling drops. At that time, sleet will turn to freezing rain. Later tonight, even the temperatures at ground level eventually warm into the middle thirties and precipitation will be all rain.

Accumulations from snow this evening will be highly variable, but generally between one to three inches in the Twin Tiers. Most locations will fall into the one to two inch range. Tonight's icy mix is expected to accumulate to between .1" and .2" before precipitation becomes all rain. Tonight, south winds may be occasionally gusty, with some gusts around thirty miles per hour likely.

Wednesday starts with milder air, and temperatures in the upper thirties to around forty by the early afternoon. A few light showers are possible through the day. By the late afternoon and evening, winds will shift northward as colder air returns behind a cold front. A few snow showers/flurries will be possible. Wednesday night, the frontal boundary stalls just south of our area. This will keep the possibility of snow showers in the forecast Wednesday night into Thursday, with the best chances in Pennsylvania.

After a few early snow showers and flurries Thursday, expect a little afternoon sun, but very little warming. Highs will only reach the upper teens. Thursday night will be quite cold, skies will be mostly clear and a few locations cold have temperatures falling just below zero late in the night.

Friday into the weekend, temperatures warm to near average levels with highs in the upper thirties under a mix of sun and clouds. A few light snow showers are possible Saturday night into Monday with a weak clipper system. However, no significant accumulation is expected.
