The model consensus is for low pressure to track from central PA to
northern Vermont Saturday to Saturday night. As the low passes to
the east and northeast, cold air advection will move into western
and north central NY. This system is moisture laden so as colder air
moves into the region, snow showers are likely from west to east
through Saturday night. Minor lake enhancement expected through
Saturday night as lake induced instability is lacking with 850mb
temperatures only falling to around -6C by Sunday morning. An inch
or two of snowfall accumulation is possible mainly at higher
elevations east of Lake Erie and Lake Ontario
