Area Forecast Discussion
National Weather Service Binghamton NY
718 PM EDT Wed Sep 17 2025

.SYNOPSIS...
Conditions will warm up Thursday before a cold front brings cooler 
air to the region Friday and this weekend. There will be a chance 
for frost, especially in the higher elevations, Friday night. Warmer 
weather then returns next week.

&&

.NEAR TERM /THROUGH THURSDAY NIGHT/...
Low chances for showers will remain in the forecast for portions of 
Northeastern PA and the southern Catskills as a coastal low 
continues to slowly drift along the coast today and tonight. 
Coverage will be isolated and showers will be light. An isolated 
thunderstorm cannot be ruled out. Shower chances then diminish by 
Thursday as the low moves further up the coast. Elsewhere, high 
pressure will continue to be in control. A fairly dry cold front 
will approach the region from the north late Thursday night/early 
Friday morning. While moisture is limited, a few spotty showers will 
be possible across North-Central NY.

Temperatures tonight will generally be in the 50s, though a few of 
the typical cooler areas may dip into the upper 40s. There will be 
some cloud cover, but light winds and a shallow inversion should 
lead to fog in the valleys and eventually some hilltops as it lifts 
out after sunrise Thursday morning. Temperatures then trend warmer 
tomorrow as highs will be in the upper 70s to low 80s. The lows 
overnight will be quite similar to tonight, mostly in the 50s. Winds 
begin to increase ahead of the front so while fog is expected once 
again, it may clear out earlier than it has previous mornings.

&&

.SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/...
The aforementioned front will drop south through the region on 
Friday and bring a cooler end to the week. Being on the backside of 
a fairly broad trough, the coldest air will be displaced just east 
of the region. Still, north to northwest flow will keep conditions 
much cooler into the weekend as highs will only be in the 60s and 
70s and lows will be in the 30s and 40s. This forecast update kept 
the previous forecasted temperatures, dewpoints, and lows for Friday 
night. Under clear skies and calming winds, good radiational cooling 
is expected with the potential for patchy frost in the higher 
elevations. Saturday night will be milder as the trough moves east 
though a few areas may become just cold enough for frost.

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
A ridge moves back into the region by Sunday and temperatures 
will trend warmer through early next week. A trough/low will dig
across the Central US and will break the current pattern 
allowing for a better moisture stream into the region. There is 
uncertainty though with where this trough will be located and 
what it means for shower chances. Given this uncertainty, NBM 
guidance was favored as it has slight to low chance PoPs (<35%) 
to start the week with the multiple weak disturbances that will 
move through and around the Northeast.

&&

.AVIATION /00Z THURSDAY THROUGH MONDAY/...

High pressure and mostly VFR conditions are expected through the
period. 

Areas of valley fog should develop overnight/early tomorrow 
morning, impacting ELM with LIFR conditions. Morning fog will
lift around 1300 - 1330Z and then all VFR from there. 


Outlook...

Thursday night through Monday...VFR, except typical valley fog 
likely each late night/early morning for at least KELM.

.BGM WATCHES/WARNINGS/ADVISORIES...
PA...None.
NY...None.
