.SYNOPSIS...
Rain and snow is expected overnight with significant accumulations
limited to higher elevations. Relatively mild temperatures will
continue until a cold front crosses Wednesday night.

.NEAR TERM /THROUGH TODAY/...
Update to adjust PoPs across the northeast as a spoke of
precipitation rotates around the departing low. Upped snow
accumulations slightly here as well. Patchy drizzle was also added
to most areas...with a few areas of freezing drizzle possible in
the highest elevations. Steady or slightly rising temperatures are
still forecast as well.

&&

.SHORT TERM /TONIGHT THROUGH THURSDAY NIGHT/...
Relatively mild into Wednesday ahead of an approaching cold front
for Wednesday night into Thursday. Above average temperatures will
continue into Wednesday night, before colder temperatures work
across the region Thursday. Mainly chance POPs for rain showers
Wednesday into Wednesday night, mixing with and changing to snow
showers Thursday, as temperatures fall toward the seasonal norms.

&&

.LONG TERM /FRIDAY THROUGH MONDAY/...
Several hard to time impulses passing through the mean northwest
flow will result in periodic snow chances, with possible accumulation
for the weekend with colder flow over the lakes. Temperatures
will average near 5 degrees below the seasonal norm.

Conditions are highly variable at present. VFR conditions are
present from PIT on southwest, with IFR/LIFR noted to the east.
Expect most terminals to settle back towards MVFR/IFR with time in
the wraparound moisture, with continuing pockets of LIFR in
drizzle and snow. Precipitation coverage will taper with time,
with some rain and snow showers continuing along the ridges into
midday. Ceilings may lift to MVFR for a time before sinking back
towards IFR after sunset. North to northwest winds should remain
mostly 10 knots or less.
