Rain will overspread the area from southwest to northeast today and continue tonight. An area of freezing rain is expected across the northern half of Jefferson County and portions of the higher terrain in Lewis County. There is also a low chance for a brief, very light period of freezing rain just south of Lake Ontario this evening. Otherwise, most areas will remain above freezing with just plain rain.
Rain and increased snowmelt will result in significant runoff and the potential for flooding this weekend through early next week, mainly east of Lake Ontario where significant snowpack remains across higher elevations. The threat for flooding is much lower across Western NY.
A notable warming trend is expected through Saturday though above normal temperatures are forecast through the middle of next week. Early signs point to a pattern shift later next week with a return to colder temperatures.
