AREA FORECAST DISCUSSION
National Weather Service Albany NY
632 AM EST Fri Mar 3 2023
.SHORT TERM /6 PM THIS EVENING THROUGH SUNDAY NIGHT/...
Winter Storm Warning in effect for portions of the Adirondacks,
Schoharie Valley, Helderbergs, Rensselaer Plateau, Lake
George/Saratoga region, northern Berkshires and southern Vermont
this evening through Saturday...
Winter Weather Advisory in effect for the remainder of the area
outside of the mid-Hudson Valley this evening through
Saturday...
The leading edge of precipitation will be along a strong
mid level axis of frontogenesis and a band of heavy snow will
track northeast through the region during the evening and
overnight. Strong south to southeast boundary layer flow along
with isentropic lift will add to the low level forcing and
moisture advection, but also warm a deep layer of the
atmosphere. The warm nose will be near 700 hPa and build as far
north as perhaps the Mohawk Valley and VT/MA border through the
night. The maximum upward motion is largely below the DGZ but
lots of moisture and precipitation could make up for what should
be considerably below climatology SLRs.
So, snow transitions to mixed precipitation through the night
from the Mohawk Valley and VT/MA border and points south. The
mix will be with mainly sleet, except some freezing rain is
possible in parts of the eastern Catskills, southern Taconics,
southern Berkshires and NW CT. So, areas such as the Capital
Region to southern Saratoga, and the northeastern Catskills may
need to get upgraded to warnings, if confidence increases for 7
inches of snow but for now 4 to 8 inches is most likely in those
areas. Downsloping could reduce snow amounts in the Hudson
Valley as well as boundary layer winds turn more southeast and
east after midnight and through Saturday morning.
