Area Forecast Discussion
National Weather Service Binghamton NY
203 AM EDT Thu Oct 16 2025

.SYNOPSIS...
High pressure will build into the region through the remainder
of the week. A cold frontal boundary with our next chance of
showers moves in for Sunday and Monday.

&&

.NEAR TERM /THROUGH TODAY/...
High pressure builds in tonight through Thursday night with clearing
skies in most areas. There will still be some gradient of NW flow
through tomorrow thus prime radiational cooling and widespread frost
in the active growing areas seems less of a concern for tonight than
might be expected. Still looking at overnight lows in the 30s
tonight and highs in the 50s again on Thursday. With continued NW
cold NW flow across Lake Ontario at 850mb...will nudge up the NBM
cloud cover just a bit using NBM90 grids on Thursday as moisture
condenses along the LCL and CCL. There`s much less pressure gradient
forecast on Thursday night where frost in the Finger Lakes and
Wyoming Valley areas may be prolific as temperatures reach the lower
to mid 30s. Will reserve Frost Advisories for this time period
rather than tonight. Upper 20s will be possible in some parts of the
Catskills and the Twin Tiers as well.

&&

.SHORT TERM /TONIGHT THROUGH 6 PM FRIDAY/...
High pressure remains in control at the surface with a thermal ridge
building into the Northeast which will allow for a slight warming
trend to begin this weekend. Precipitation is expected to remain at
bay during this time with high temperatures rising into the lower-
mid 60s for Saturday. Some mid-high clouds may punch through the
ridge axis aloft for only a partly sunny day Saturday, but Friday is
likely to be quite sunny in most areas.

&&

.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
An active pattern sets up during this period as a longwave trough
sets up along the northern tier of the U.S. with fairly amplified
shortwaves cutting underneath. Model spreads become much more
uncertain in handling the upper level heights and there are also
timing differences in the ensembles, but it still looks like
reasonably high probabilities for rain exists in the Sunday night-
Monday timeframe and then again Tuesday or Wednesday. South winds on
Sunday afternoon are likely to be blustery with potential gusts over
30 mph. We`ll keep an eye on this. Lake effect rain showers in
between the two frontal systems will keep the NY counties unsettled
throughout.

&&

.AVIATION /06Z THURSDAY THROUGH MONDAY/...
VFR conditions are expected through much of the TAF period with
high pressure in control. Some high clouds can stream across
RME and SYR early this morning as they push down from the north.
Some clouds have formed downstream of the Finger Lakes near ELM
and ITH which may lead to a scattered deck of clouds briefly
around 3000 feet AGL over the next several hours. Some patchy
valley fog cannot be ruled out as well through 12Z, mainly
around ELM, but winds remain elevated enough just above the
surface that confidence in its formation remains low.

Breezy north-northwest winds are expected late this morning
through the afternoon with frequent gusts of 15-20 knots, along
with occasional gusts around 25 knots, before diminishing this
evening.

Outlook...

Later Thursday night through Saturday...Mainly VFR. Chance of
valley fog each morning.

Sunday and Monday...Restrictions possible with a front moving
through, especially later in the day Sunday and into Monday.
