The episode as NWS BGM wrote it up.
Warmer than average temperatures during the previous three months along with insufficient rainfall, much below average streamflows, groundwater levels and dried out soil conditions continued Severe Drought conditions in parts of Northeastern PA. Conditions lingered through the 17th in Lackawanna, Pike and Wayne counties when sufficient precipitation allowed for a reduction in drought severity back to just abnormally dry conditions. Severe drought continued through the 31st for a small portion of southern Luzerne county.

Area Forecast Discussion
National Weather Service Binghamton NY
1149 PM EST Sat Nov 30 2024
.SYNOPSIS...
Cold weather expected through the weekend into early next week
under as a upper level trough remains in place. Lake effect snow
will remain north of our region with mainly flurries at times
this afternoon through Sunday but the band shifts south Sunday
afternoon, impacting the NY Thruway corridor.
&&
.NEAR TERM /THROUGH MONDAY/...
1140 PM Update...
Light flurries continue over Cayuga, Tompkins, and Cortland
counties with temperatures in the low to mid 20s. Not many
changes were need this update, made slight adjustments to
update temperatures and dew points with current observations.
650 PM Update:
Partly cloudy skies out there this evening with a few, isolated
light snow flurries on-going across Cortland, Cayuga, Onondaga
and Oneida counties. Temperatures have already fallen back into
the 20s and low 30s areawide. It will be quite cold tonight with
lows in the 10s to low 20s over the region. Another cold and
partly cloudy day (with a few isolated flurries) on tap for
Sunday; highs in the mid-20s to lower 30s expected. The lake
effect doesn't shift south into Central NY until the Sunday
evening hours. Touched up PoPs, and increased details in the
PoPs/wx grids for when the lake effect snow band is expected to
shift south Sunday evening/night.
Was contemplating whether the current winter weather advisories
for S.Cayuaga and Onondaga should be extended in time through
at least Monday evening, as the 18z CMC regional model keeps
steady lake effect snow going through the day...however the HRRR
and 3km NAM dissipate or break up the lake effect snow bands at
differing times on Monday; so confidence remained low enough to
not extend advisories yet. Will wait and take a look at newer
guidance before making any decisions on this aspect of the
advisory...as uncertainty does remains a bit higher than usual
on when the lake effect will break up. So for now, the winter
weather advisory remains in place 10 PM Sunday through 10 AM
Monday morning for the two forecast zones noted above.
200 PM Update...
With the stratocumulus layer sitting right at the dendritic
growth zone, there has been widespread light flurries across the
region this morning into the afternoon. Forecast soundings show
that the DGZ will remain saturated into the evening so flurries
have been added into the grids through the afternoon. Some
flurries have been added in for tomorrow as well as many
forecast soundings show a return of the stratus layer at the DGZ
so there will be potential once again mainly north of the
Southern Tier. With a long wave trough set up overhead and
persistent NW flow under it, we will remain cold through the end
of the weekend with temperatures struggling to get above
freezing.
Lake effect snow is expected to stay north of the region and
mainly impact the northern Tug Hill through at least mid day
tomorrow before a shortwave moving in begins to turn the flow
more northwesterly. Forecast soundings late Sunday afternoon and
overnight are favorable for organized snow bands into Onondaga
and Cayuga counties. As of now, the forecasted environment is
not too favorable for deep inland extent of the snow bands so
the heaviest snow accumulations will be limited to the northern
western portion of Onondaga and central Cayuga counties.
&&
.SHORT TERM /MONDAY NIGHT THROUGH TUESDAY NIGHT/...
West to northwest winds look to continue into Monday. The flow
coming off of a warmer Lake Ontario should result in additional lake
effect snow showers. The most concentrated area of snow showers
given the wind direction should be focused into eastern Cayuga and
western Onondaga counties where a winter weather advisory has been
issued for. Even though the QPF looks light given a lack of forcing
higher snowfall ratios should be able to offset that some. Snowfall
totals of around 4 inches in spots look likely at this time with
lower totals further southeast. Some snow showers may advance
eastward into Steuben county as well from Lake Erie. These also look
to be fairly light Monday. While several degrees warmer, highs still
look to only get to around freezing.A break in the action should
occur Tuesday night with winds shifting to southwesterly ahead
of an approaching clipper system.
&&
.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
Modeling and ensemble guidance still some differences in the
overall track of the clipper. The track looks to be north of
the region across New England Wednesday and Thursday. Still,
enough lift looks present for an area of light snow to develop
Wednesday afternoon and night ahead of a warm front. Might have
to watch the Froude number with this event to see if there are
any areas of enhancement or missed locations in terms of QPF.
Ground temperatures should finally be cold enough for
accumulations in valley locations as well. Another inch or two
of fluff could occur with possibilities expanding into more of
the region. If the track shifts slightly to the north less QPF
would be observed in NE PA and the southern Tier of NY.
Given the southerly flow, temperatures may warm a few degrees above
freezing as well in NE PA Wednesday. So brief mixes with rain can
not be ruled out in the Wyoming Valley. Temperatures still generally
20's and 30's given the cloud cover and general flow pattern.
While to early to get a pinpoint on exact details this far out this
looks like a favorable setup for snow squalls ahead of the main cold
front early Thursday. This should transition to another Lake
Effect event with west-northwest flow into Friday. Yet another
clipper may follow with additional snow showers and Lake Effect
snow showers on Saturday.
A fairly potent cold airmass looks to move in Thursday through
Saturday. This looks to knock temperatures back into the teens and
20's. Model soundings show an increase in winds as well, so wind
chills near 0 at times is not out of the question.
&&
.AVIATION /06Z SUNDAY THROUGH THURSDAY/...
ITH and BGM should see ceilings dipping in and out of MVFR
conditions over the next couple hours as some lake clouds
continue to move across the region. VFR conditions expected for
all terminals through tonight and tomorrow. Ceilings at ITH and
BGM could fall into MVFR again tomorrow afternoon, but
confidence is not high enough at this time to include it in the
TAFs. Winds will remain blustery, gusting to 18-25 kts across
the region out of the WSW.
Outlook...
Sunday Night...Lake Ontario snow band will push south and should
bring restrictions to SYR and/or RME.
Monday and Tuesday...A shift to NW winds and a multi-lake
connection will increase the probability of lake effect snow
and associated restrictions at CNY terminals, possibly even
extending as far as AVP at times.
Wednesday into Thursday...A low pressure system moving through
Southern Canada may bring scattered snow showers with associated
restrictions.
