724 PM EDT Mon Sep 29 2025
.SYNOPSIS...
High pressure will result in a prolonged period of dry weather
across the area through the entire week. Temperatures will
remain above normal through Tuesday, before much cooler air
moves in Wednesday and Thursday. There is a potential for some
areas of frost Wednesday and Thursday nights, especially in the
sheltered valleys.
&&
.NEAR TERM /THROUGH TUESDAY NIGHT/...
1225 PM Update:
Surface high pressure and weak ridging continues to bring warm
weather to the area. Higher clouds extending from the tropical
activity off the Southeast coast is bringing filtered sunshine
this afternoon, instead of the full sunshine we saw yesterday.
The higher clouds will stick around tonight, especially across
Northeast PA. This combined with the warm airmass in place will
limit radiational cooling potential somewhat and result in low
temperatures that are slightly above normal. Lows are expected
to be in the upper 40s to mid 50s for most of the area.
Tuesday will be the final day of this stretch of above normal
temperatures (until closer to this weekend) with highs mainly in
the 70s. Similar to today, some higher clouds may result in
filtered sunshine (especially across Northeast PA), but these
will be gradually retreating to the east. Mostly sunny skies are
expected elsewhere, especially farther to the north in Central
NY. Then mostly clear skies are expected Tuesday night with lows
in the upper 30s to mid 40s as a Canadian high pressure system
pulls in cooler air.
&&
.SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/...
1225 PM Update:
Much cooler temperatures are expected for Wednesday and Thursday
with highs only in the 60s for the large majority of the area,
and even some upper 50s across some of higher elevations.
Otherwise, sunny skies are expected both days.
Most noteworthy, with clear skies, light winds, and a cool
airmass in place, conditions will be ideal for radiational
cooling both Wednesday and Thursday nights (especially Wednesday
night). Lows are expected to get down to the 30s for the large
majority of the area Wednesday night and mid 30s to mid 40s
Thursday night. Areas of frost will be likely Wednesday night,
especially in the sheltered valleys. There may also be a few
areas across the Catskills and northern Oneida County that may
reach freezing, or even drop below freezing Wednesday night.
Eventual frost/freeze headlines are looking increasingly likely
for at least Wednesday night.
&&
.LONG TERM /FRIDAY THROUGH MONDAY/...
1225 PM Update:
High pressure will keep conditions dry Friday, through the
weekend, and into the beginning of next week. With the high
positioning itself to our east, a southerly return flow will
develop and as a result, temperatures will once again return to
above normal for early October. After highs in the upper 60s to
mid 70s Friday, highs in the mid 70s to near 80 degrees are
expected Saturday through Monday.
&&
.AVIATION /00Z TUESDAY THROUGH SATURDAY/...
High pressure will continue VFR conditions (with possible
exception to ELM) through this TAF period with SCT- BKN cirrus
ceilings occurring downstream from the western Atlantic tropical
systems.
Chances for deep fog development at ELM are decreasing. With the
crossover temperature for ELM today being 39 degrees, and
overnight low expected of 50 degrees, conditions are expected
to be too dry for thicker fog development. However, a TEMPO
group between 09Z and 12Z for MVFR conditions is included since
fog development in general is possible. Confidence is still
medium, as climatology favors fog development, yet the
meteorological set-up isn`t completely favorable for thicker,
VLIFR/LIFR fog as ELM has seen in the past couple of days.
Outlook...
Tuesday night through Saturday...VFR with localized VLIFR fog
possible at valley airports.
