Radar Evolution/Resultant Snowfall

• Initial short-wave sweeps convective line of rain/snow showers across the region between 00z and 03z on the 25th

• Several reports of thunder-snow across PA

• Later on, during the pre-dawn hours, lake-enhanced snow showers become more widespread

• Good forcing ahead of upstream short-wave

• Air mass only marginally cold enough for lake effect mechanics to really kick in at that point

• By 12z-14z on the 25th, some 3-4" snowfall amounts observed near Ithaca; and also in parts of Onondaga/Madison/Oneida counties
