The snow will be confined mostly to the hills south of Syracuse and Buffalo. However, residents could also see some slushy stuff at lower elevations overnight Sunday and again Monday.
5 May 2017 – According to the National Weather Service, Western New York could see up to 3 inches of snow on Saturday night and Sunday, particularly along the higher terrain of the western Southern Tier. The same areas could get an additional 1 to 2 inches Sunday night.
Smaller amounts of snow could fall in the Tug Hill/western Adirondacks area and in the hills south of Syracuse, particularly at 1,200 feet elevation or higher.
Snow in May isn’t unheard of in Upstate, of course, but it doesn’t happen very often.
