After a soaking rain which dropped up to an inch of rainfall bringing creeks and streams to their banks, colder air will slowly cover WNY slowly changing the rain to snow.
Temperatures will slowly sink through the 30s allowing rain to make the switch to snow during the day. The slush will start to accumulate several inches on the Southern Tier hills through the afternoon while the lower elevations and Northtowns receive only minor amounts.
Temperatures drop to near the freezing mark as winds increase beginning to drive lake snow bands inland across much of WNY. Hilltops in Chautauqua county will see the heaviest snow, but even the Northtowns will start to see accumulations by Wednesday morning.
