1) Rain showers begin late this afternoon or early evening, and the rain should change to snow around 6 AM tomorrow before ending. Accumulations should be from a coating to an inch at most.
2) There could be some light snow Sunday morning, but the main precipitation event looks to be rain Sunday night into Monday morning. The accumulating snow will be well inland.
3) Once again, it looks like mostly rain for Long Island on Wednesday.
