Winter Storm Warning for Allegany county and Potter county until 10AM Tuesday.  Heavy slushy accumulation of 6+ inches, heaviest on high elevations for advised area and a few more inches for the warned areas.  

A major coastal storm will send some rain in from the south by mid or late afternoon. The vertical lift of this storm will cool the air enough so that the rain will turn to a mix and/or some slushy water-laden snow by late Monday and Monday night on the hills Well SE. At this point, the best chance for moderate to heavy accumulation will be toward the Genesee Valley Monday night, and there may be moderate accumulations Orleans Co & Genesee Co. as well as counties Well SE. There will also be an increasing somewhat raw breeze out of the ENE on Monday, strongest near Lake Ontario. Light snow  on Tuesday will wind down to flurries. Another storm system will bring rain & mixed showers during Wednesday turning to snow showers later Wednesday night as a seasonably cold pattern reestablishes itself later next week. Snow showers & some lake snow, mainly south, will be present at times Thur-Sat, with better organization Friday.

MONDAY NIGHT: Rain will mix with sleet and turn to snow even on the Niagara Frontier by late evening. Any accumulation will be slushy and water-laden, with the best chances for 6+ inches accumulation well east and possibly well southeast.  Overnight lows near 30..
