Central PA Autumn 2026

Low of 44 here.  Weekend forecast has been deteriorating quickly, as that coastal storm wants to stay nice and tucked -- words that hopefully we're uttering come January.  Crystal ball says we end September with a mean temp of 69.2, a little over a degree above average and good for a tie for 25th place all-time.  Book it.

Let's hope your (ours) college team fares better tomorrow than your (not mine  ) NFL team did last night. Geez, that was ugly.

It was frost everywhere out here this morning. No one else had frost?

Well, maybe everywhere's a little bit of a stretch, but it was on all the roofs and cars out here early this morning.

I don't know what you're talking about 

Buy yeah, seems like a lost season.  Gonna be a tough watch this year.  The issues are too many to list.  As for PSU, really bad news about Koby Howard.  Thinking they'll be taking some tough losses eventually too, just hopefully not tomorrow night. Football, what I let it do to me.  Aye.

Per my NWS forecast, I could see a high end qpf of 1.5" from this storm. Wind here gusts to 30mph, but not likely in my sheltered backyard.

.DISCUSSION...
KEY MESSAGE 1: Nor`easter will bring gusty winds and periods of
rain for the first weekend of Fall

Sensible weather conditions continue to trend incrementally
bearish on the margin particularly later Saturday through
Sunday as wind and rain impacts extend westward from powerful
Nor`easter tracking toward the NJ/Long Island/southern New
England coast. Latest model guidance favored a minor increase in
wind gusts and westward expansion of higher POPs/QPF to the
Allegheny Front. Locations throughout the Susquehanna Valley
will see the most persistent rain and strongest wind gusts up to
40 mph. We lowered max temps a few degrees Sunday due to the
combination of clouds, wind, and rain. We can`t rule out some
localized/minor impacts (sporadic power outages and tree damage)
due to the wind gusts especially across the eastern portions of
the CWA.

It`s still hard to say how far west the precip will reach with
the western Alleghenies most likely to continue an extended dry
stretch through much of next week. As the nor`easter lifts to
the northeast, conditions should steadily improve by the middle
of next week with temperatures poised to rebound above the
historical average for the end of September.

.AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...
Prevailing VFR flight cats through tonight with increasing high
to mid level clouds from southeast to northwest. Localized vis
restrictions may occur in valley fog tonight and have kept
mention of VCFG at western and central airfields. LLWS forecast
throughout ZNY sector tonight as a 45-60 knot low level jet
moves into the area on the west-side of powerful Nor`easter.
Rain could reach KMDT/KLNS by Saturday afternoon/evening.
Highest confidence in sub-VFR will be over the eastern half of
the airspace through Sunday. Winds/gusts from 330-030 degrees
will increase Saturday into Sunday maxing out around 30kts.

Outlook...

Mon-Wed...Improving conditions trending VFR by midweek.
