BGM hitting on the potential as well...mentioning potential banding. Won't factor much for me in the SE corner of their CWA but definitely will to the north of here
Meanwhile, a surface low will start to develop near Long Island
and this low will deepen quickly as it tracks into western New
England. The approaching upper level trough starts to become
neutral to negatively tilted, slowing down its eastward
movement. 12Z model guidance shows an area heavy precipitation
developing Wednesday night from Steuben County northeast into
the Adirondacks. The latest guidance shows an area of PVA
entering western NY and enhancing forcing ahead of a strong
150+ knot jet at 300mb, with the bullseye of the left exit
region passing the Western Southern Tier and into the Tug Hill
by early Thursday morning. As the column continues to cool
Wednesday night, dynamic cooling should cause precipitation
to quickly change from rain to snow after 0Z Thursday from west
to east. At this time, the highest confidence for possible heavy
snow will be in line with the area mentioned above...from Steuben
County to Oneida County, where more than 4 inches may fall. It
is looking likely that a band of heavy snow is going to set up
somewhere, based on the impressive forcing, and amounts could
end up much higher where this band ends up.
