Now about 50/50 snow / sleet. Sleet will likely begin to dominate within the next half hour. Total snow accumulation today hit 1.2". 850mb temperatures are around -1C in Keene right now, and will likely exceed freezing within the next hour. Sleet will continue through 6pm. As the 850mb - 750mb layer continues to warm, precipitation will likely change to freezing rain.
Surface temperatures may drop slightly through midnight, with minimum temperatures around 28 to 32 this evening before beginning to rise as warm air advection overpowers surface cold air damming. Any freezing rain should be finished before midnight. Some ice accretion is possible, but will reach at the very most a tenth inch.
