.SYNOPSIS...
High pressure will produce a prolonged period of dry weather
across the area through the entire week. Temperatures will
remain well above average through Tuesday, before much cooler,
more fall like air moves in Wednesday and Thursday. There is
even the potential for some areas of frost, Wednesday and
Thursday nights, especially in the sheltered valleys.
&&
.NEAR TERM /THROUGH TUESDAY/...
Broad surface high pressure centered over the area with weak
ridging aloft will lead to another very warm day today for late
September. Areas of morning valley fog will clear between
12-14Z, giving way to sunshine. A blanket of high clouds
associated with the tropical activity off the Southeast coast
will gradually push north late this morning and into the
afternoon, especially across NE PA, but skies will still
generally be partly to mostly sunny despite the filtered
sunshine. Highs this afternoon will range from the mid 70s to
near 80 degrees. The shield of high clouds will stick around
tonight and then retreat to the south and east during the day
Tuesday. Lows tonight will be mainly in the upper 40s to the mid
50s. NE PA will turn out mostly sunny by Tuesday afternoon,
while CNY sees bright sunshine throughout the day. High
temperatures will remain above average for one more day Tuesday
with much of the area well into the 70s. The Wyoming and
Delaware River Valleys in NE PA will make a run at 80 degrees.
&&
.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/...
A fresh, sprawling surface high centered over northern Ontario
and Quebec will push south and east Tuesday night into Wednesday
and remain centered over the region into Thursday promoting
continued dry conditions. This Canadian high will be drawing in
much cooler air from the north, bringing the return of more
fall-like conditions. High temperatures are expected to be near
to slightly below average Wednesday and Thursday. Highs
Wednesday will mostly be in the low to mid 60s, with some of the
higher terrain in CNY and the Catskills stuck in the 50s, while
a few of the valleys in NE PA remain a bit warmer in the upper
60s to near 70. Highs will be generally in the 60s areawide on
Thursday. With this much cooler air mass settling in, there is
the potential for areas of frost Wednesday night into early
Thursday. With the growing season still active, there looks to
be a good chance for some frost advisories as we get closer with
lows ranging from the mid 30s to the low 40s. Parts of the
Catskills and toward the Tug Hill can be even colder closer to
the freezing mark.
&&
.LONG TERM /THURSDAY NIGHT THROUGH SUNDAY/...
Areas of frost may be possible again Thursday night, mainly in
the sheltered valleys in the Catskills and toward the Tug Hill,
then we`ll have a moderating trend once again in terms of
temperatures Friday into the weekend ending our brief taste of
autumn.
Surface high pressure will continue dominating our weather
pattern through the weekend and potentially beyond keeping
conditions dry. This surface high is expected to gradually slide
to the east and become centered off the coast, setting up more
of a southerly flow which will advect in warmer air, especially
by Saturday and Sunday. Highs are expected to rise from the
upper 60s and low 70s Friday to the mid 70s to near 80 degrees
by Sunday. Overnight lows also rise back into the 40s and 50s.
&&
.AVIATION /12Z MONDAY THROUGH FRIDAY/...
Valley fog across the area with current IFR and lower
conditions at RME and ELM will lift by mid-morning. High
pressure will bring VFR conditions into the overnight hours
across the area with winds light and variable. Fog may once
again return to ELM and RME tonight, but confidence is not high
as high clouds are expected across the area through the evening
hours and wind above the surface may be strong enough to stave
off fog development. Given the climatology of ELM, confidence
is high enough to include TEMPO LIFR conditions tonight with
patchy fog developing.
Outlook...
Tuesday through Friday...Mainly VFR, other than typical valley
fog formation especially KELM late each night through dawn each
morning.
