Already, somewhat cooler temperatures have begun to infiltrate the region behind the front that moved through yesterday. The upper level low causing the cloudiness over the region will lift slowly north into southern Quebec. West winds today will shift to the southwest ahead of a weak shortwave that will swing through after midnight. Winds shift back to the west and intensify Monday morning. Scattered precipitation will move into New York and New England past midnight. Most of the precipitation will remain north of the area, and model guidence is spitting out less than a tenth inch W.E. across southern NH, with closer to .2" to .4" W.E. across northern New England. Nevertheless, as the shortwave moves through tonight, H85 temps will fall to around -2 to -4C, with 1000-850mb thicknesses around 1305m and 850-700mb thicknesses around 1505m 7am Monday morning. This will support some snow and/or sleet mixing in with any precipitation that falls between 4am and 10am. This possibility is best across higher elevations.
