Area Forecast Discussion
National Weather Service Binghamton NY
244 AM EDT Mon Oct 6 2025

.SYNOPSIS...
High pressure dominates and continues the dry weather pattern with
well above normal temperatures across the region through
Monday. A passing cold front will bring a batch of rain and
possibly a storm late Tuesday into early Wednesday, followed by
dry and cooler weather through Saturday.

&&

.NEAR TERM /THROUGH TONIGHT/...

An expansive upper level ridge of high pressure remains firmly
in place aloft, with full sunshine. At the surface, high
pressure centered to the south and east of the area has placed
our region in light southwest return flow. With the clear sky
and very light wind, we are getting wide diurnal ranges between
cool mornings and warm afternoons with highs around 15 to 20
degrees above average temperatures for this time of year.

With warm air advection continuing, temperatures will not be
quite as cool as prior nights. Overnight temperatures tonight
are expected to only go as low as into the mid 50s to low 60s.

&&

.SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/...

High pressure begins to slide east and out to sea as an incoming
frontal system approaches. A large upper level trough drives the
system, with an embedded wave helping to push the front along
and towards our area. Due to this system being a little
unorganized, it`ll likely be slower in nature. PWAT values
increase to up to an inch and a half with this front, with
accumulating rainfall likely spanning from Tuesday morning
through Wednesday afternoon. With current drought conditions,
any hydrological issues such as flash flooding is not a concern.
A few hundred J/kg of CAPE could bring some embedded ordinary
storms as the front passes through, mainly between Tuesday
afternoon and evening timeframe.

After the passage of the front with the much-welcomed rain, there
will be a solid 14-18 degree drop in highs Wednesday. After
upper 50s-mid 60s Wednesday, cold air advection will send
temperatures to mainly 30s Wednesday night with a mostly clear
sky and north-northwest wind. Some of the highest terrain area
could get around freezing, and sheltered valleys also could get
frost.

&&

.LONG TERM /THURSDAY THROUGH SUNDAY/...

Back to dry weather for the remainder of the week, with cooler
temperatures yet also fairly close to climatology.

A large high pressure will move directly over the region
Thursday-Friday, and still at least be dominant even into the
start of the weekend. Ideal radiational cooling set up is likely with
light-calm winds and clear sky Thursday night, and thus our
highest chance for areas of frost with lows of upper 20s-mid
30s; more like upper 30s near the Finger Lakes and Wyoming
Valley. This of course is not at all unusual given the time of
year. That will be bookended by mid 50s-lower 60s for highs
Thursday, and upper 50s-mid 60s on Friday.

Many members of model ensembles depict an upper level wave or
even low attempting to dig into the western Great Lakes
Saturday, yet skewing south with time. Our air mass looks more
likely to remain dry with surface high pressure hanging on.
Thus rain chances are around or less than 10 percent during he
weekend, and the National Blend of Models is around climatology
with highs of 60s-near 70 and lows of mid 30s-lower 40s.

.AVIATION /06Z MONDAY THROUGH FRIDAY/...
Very quiet weather continues through at least the next 24 hours
as high pressure remains in control. VFR conditions are expected
for the majority of the time and locations. Have backed off on
the threat of valley fog this morning given the strength of
winds and amount of mixing in the boundary layer. Surface winds
remain calm, but fog typically has a more difficult time forming
and remaining in place if winds just above the surface are 15 to
20 kt...which is what is being indicated from model guidance and
from the latest VAD wind profiler on the KBGM radar. So...at
this time will just go with a 3 hr tempo at ELM for IFR fog
between 09-12Z. Light winds this morning will pick up from the
southwest around 7-11 kt.

Outlook...

Monday night...VFR. Local LIFR-VLIFR fog possible late.

Tuesday through Wednesday...Flight restrictions expected in periods
of rain. SSW-NW wind shift. Gusts 20 kts.

Thursday and Friday...VFR. Local morning valley fog.
