A strong area low pressure moved over the Great Lakes region and a warm front lifting north early in the day put the area into the warm sector of the system, ahead of an approaching cold front. While instability was limited, there was strong wind shear in place, and a line of gusty showers and thunderstorms along and ahead of the cold front produced locally damaging wind gusts.

The episode as NWS BGM wrote it up.
A strong area low pressure moved over the Great Lakes region and a warm front lifting north early in the day put the area into the warm sector of the system, ahead of an approaching cold front. While instability was limited, there was strong wind shear in place, and a line of gusty showers and thunderstorms along and ahead of the cold front produced locally damaging wind gusts. There was also a tight pressure gradient in place which resulted in strong, locally damaging non-thunderstorm synoptic winds prior to the cold frontal passage as well.

Area Forecast Discussion
National Weather Service Binghamton NY
333 PM EDT Sun Mar 16 2025
.SYNOPSIS...
A strong cold front will move through the area this evening,
which will bring rain showers, scattered thunderstorms and windy
conditions along with a chance for localized flooding. Showers
shift east by Monday afternoon, with temporarily cooler weather.
Warm temperatures return on Tuesday and Wednesday with plenty
of sunshine expected.
&&
.NEAR TERM /THROUGH MONDAY NIGHT/...
305 PM Update
A severe thunderstorm watch has been issued for western portions
of the forecast area, including the central southern tier of NY
and the western Finger Lakes; which is in effect until 7 PM this
evening. The atmosphere is destabilizing in this area and a
developing line of thunderstorms in western NY/PA is moving this
way. The line of storms will likely continue trekking east,
reaching the I-81 corridor by 5-6 PM this evening, then gradually
weakening as it reaches the Catskills/Mohawk Valley and Poconos
by 6-8 PM. The Slight Risk (level 2 out of 5) was expanded with
the midday SPC outlook update...now reaching the I-81 corridor
with a Marginal Risk (level 1 of 5) now covering most of the
rest of the CWA, except far eastern areas. The biggest concern
is still the potential for strong, gusty and isolated damaging
winds. There is now also an isolated tornado potential, with SPC
including a 2% chance for most of the Central NY and NE PA.
Other main concern are the strong synoptic winds late this
afternoon and evening, with 850mb winds reaching 50-75 kts
through the afternoon. KBGM VAD wind profile is showing this
currently, with 70kt winds 1km Above Ground Level (AGL) and
80-90 kt winds at 2km AGL as of 257 PM EDT. These are very
impressive low level winds. These strong winds are occasionally
mixing down to the surface, where gusts are currently between
40-55 mph now being realized over much of the CWA. The 18z HRRR
still showing the potential for these, and even stronger winds
50-60 mph mixing down to the surface for several hours this
afternoon and evening across most of the CWA. There is even the
potential of gravity waves to occasionally drag down very
strong gusts through 6-8 PM. Therefore, the wind advisory
remains in effect for the entire forecast area, and extended the
time until 6-8 PM EDT. Also getting numerous reports of trees
and powerlines down across the area already due to these strong
synoptic winds.
Severe thunderstorm, and strong wind potential is increasing as
again the latest model guidance is picking up on the clearing
and enhanced daytime heating and instability that is heading
this way. 12z NAM and 18z HRRR now show potentially 200-400
J/Kg of MLCAPE over at least the west-central half of the CWA
as a potential squall line of low topped convection moves east
this evening. Bulk effective shear is very strong, is 45-60 kts
which will aid in organizing this strong to severe line.
The timing shows the line reaching I-81 around 5-6 PM and
exiting east of the Catskills/Poconos by around 8-9 PM this
evening. Flood watch remains in effect for Oneida county, mainly
for rapid snow melt and some rainfall, up to about 1 inch as
well. We will monitor creeks and water levels very closely in
this area over the coming 24 hours or so.
The post frontal rain will linger well into the evening hours,
especially along and east of I-81 with another quarter inch or
so of rain expected. Winds turn NW overnight and 850 mb
temperatures dropping to around 0C by daybreak. Drizzle and
light showers will continue in the moist, cool upslope NW flow.
Overnight lows dip down into the 30s and lower 40s...but most of
the precip looks to remain rain. Monday will be colder, slightly
breezy and mainly cloudy. Lingering light rain and snow showers
will continue through the first half of the day as the 500mb
trough moves directly overhead. Temperatures do not recover
very much, with highs only in the upper 30s to 40s expected.
Weak high pressure builds in Monday night with clearing skies
and diminishing winds. Cool overnight lows in the 20s expected.
&&
.SHORT TERM /TUESDAY THROUGH WEDNESDAY/...
115 PM update...
Main concerns in the short term are focused on the ridge of
higher pressure building in from the southwest and rapidly
warming air moving into the region.
Weather conditions will be generally quiet Tuesday and
Wednesday this week with no precipitation expected, but with
rising temperatures and dry weather conditions, there is an
increasing risk for enhanced fire weather conditions.
A cool/moist air mass in place Monday will be exiting to the
east/northeast on Tuesday as the northern edge of a relatively
low amplitude ridge expands from the Ohio Valley into the Mid
Atlantic and Northeast. As this occurs, 850mb temperatures will
rise from around +1 deg C Tuesday morning to about +7 deg C
Tuesday evening, and to around +12 C Wed afternoon. The initial
push of warm air and weak ridging on Tuesday will be re-
enforced and further emphasized on Wednesday as a deep trough
digs into the Central Plains and amplifies the ridge to the east
and pulls north an even warmer air mass.
The result of this pattern will be mostly sunny skies on
Tuesday with afternoon highs in the upper 50s and lower 60s. Low
dew points on Tuesday will drop RH values into the 25 to 30 pct
range. The clear skies on Tue night will allow temperatures to
fall into the 30s with recovery RH values into the 70-80 pct
range. Slightly warmer temperatures on Wed...well into the 60s
along with slightly higher dew points (into the mid 30s) will
produce another day with RH values bottoming out in the mid 30
pct range.
Light southerly winds on Tuesday will be replaced by strong
winds on Wednesday. Look for south/SE winds 15 to 20 mph and
gusts up to 30 mph.
&&
.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
115 PM update...
The warm air mass in place on Wednesday will linger Wed night
and the early part of Thu as a deepening trough of low pressure
rotates through the Ohio Valley into the East Coast. This system
will bring a period of persistent rain showers to the region,
mainly during the day Thursday, and as the cold air moves in on
the back side of the system, many of the rain showers will mix
with and potentially change to snow showers Thu evening. Surface
temperatures will fall from the upper 50s Thu morning into the
lower 40s by the early evening hours and eventually into the
upper 20s and lower 30s late Thu night.
The cold Canadian air will push in aggressively from the
northwest during the day Friday and act to produce lake enhanced
showers, mainly in the form of snow in the morning, but likely
a mix of snow and rain in the lower elevation areas Friday
afternoon. Snow accumulations will be very light to none. The
fast northwest flow (NW winds 15 to 25 mph and gusts to 35 mph)
should keep most of the snow showers southeast of Lake Ontario
and by late Friday evening the 850mb ridge axis is expected to
move in and allow the winds to back and most of the snow showers
to come to an end.
More seasonable temperatures will be felt on Saturday with
highs in the upper 40s and lower 50s. High pressure looks to
build in before the next round of showers Saturday night into
the latter part of the weekend.
&&
.AVIATION /19Z SUNDAY THROUGH FRIDAY/...
145 PM Update
A mix of MVFR and lower end VFR conditions across the forecast
area early this afternoon. Conditons are expected to deteriorate
down to MVFR/MVFR Fuel Alt areawide later this afternoon and
early evening as rain overspreads the region. A line of
thunderstorms is also expected to move west to east through the
area mainly between 20-22z at ELM, ITH and SYR, and 20-23z at
BGM...included a tempo at these sites for TSRA...not enough
confidence at RME and AVP to include TSRA just yet as the CAMs
were not showing much convection reaching these sites. Will
amend to include TSRA if probabilities increase at these taf
sites. The rain is looking slower to exit, and could linger
through at least the late evening hours. Model guidance shows a
brief wind from about 00z to 03z where CIGs improve back to
lower end VFR; confidence in this happening is only moderate.
Then, as winds shift NW CIGS and VSBYs drop back to MVFR, MVFR
Fuel Alt for all tafs sites...except IFR likely at BGM and ITH
late tonight through Monday morning.
Gusty southerly winds (occasional gusts of 30-40 kts) are
expected this afternoon, before diminishing this evening and
shifting to more west-northwesterly. LLWS is also expected
through most of the day, before dissipating this evening.
Outlook...
Monday afternoon...Post-frontal ceiling restrictions lingering
into the afternoon, then gradual improvement back to VFR between
about 21z to 24z.
Tuesday through Wednesday...Mainly VFR.
Thursday...Occasional restrictions possible along with scattered
rain showers.
Friday...Restrictions possible with scattered snow and rain
showers.
&&
.HYDROLOGY...
Moderate to locally heavy rainfall is expected today, which may
result in isolated flash flooding across Central NY and
Northeast PA. Of larger concern is this rainfall occurring in
Oneida County, particularly across northern Oneida County where
there is still between 6-12 inches of liquid contained within
the very deep snowpack. Warm temperatures are also expected,
coupled with gusty southerly winds and higher humidity. Snow
pack temperatures have risen to 32 degrees and is saturated so
rain will run directly into rivers. The warm rain will also help
accelerate snowmelt during the rainfall. The combination of the
rain and snowmelt is likely to cause flooding in parts of
Oneida County Sunday into Monday. The Fish Creek watershed is of
particular concern for flooding; both east and west branches
and especially from the confluence down through where it empties
into Oneida Lake at Sylvan Beach. However, the tributaries of
the Mohawk River upstream of Delta Lake are also looking to be
of higher concern. There is significant snow-water equivalent
in the headwaters of the branches; a big portion of which will
get sent down the branches of the Mohawk along with runoff from
any rain.
