.DISCUSSION...
KEY MESSAGE 1: Extended stretch of dry weather with minor wind
impacts from the strong coastal low this weekend

A much needed break from the rain (following one of the wettest
mid to late summer patterns on record) is expected over the
next 7 days across the majority of central PA.

A strong coastal low developing offshore NJ/Long Island/southern
New England could bring some light rain to the eastern third of
the CWA (mainly east of US-15) later this weekend, but the main
sensible weather impact from this system will be from the wind.
Breezy conditions are expected Saturday and Sunday with max
gusts 30-35 mph range over the higher terrain in the northeast
portion of the forecast area.

As the stacked coastal low moves toward the Canadian Maritimes,
temperatures are projected to rebound and climb several degrees
above the historical average heading into the end of the month.

.AVIATION /18Z WEDNESDAY THROUGH MONDAY/...
VFR will prevail tonight through tomorrow across central
Pennsylvania given the drier air in place. Ceiling restrictions
will be unlikely, as well as fog development due to E/NE flow
ranging between 5-10 kts overnight. Thursday daytime winds will
increase to between 7-15 kts with gusts up to 25 kts, especially
in the Lower Susq Valley. Marginal LLWS could be possible for
KLNS and KMDT tonight.

Outlook...

Thu-Mon...VFR favored as a developing coastal low looks to
bring subsidence overhead, though -RA and lower cloud ceilings
associated with this system may reach our eastern terminals this
weekend (20 pct chc).

&&

.CLIMATE...
Astronomical fall began Tuesday, September 22, 2026, at 8:04PM
EDT. This marked the time of the autumnal equinox when the sun
was directly above Earth`s equator. We`ll lose nearly 3 hours of
daylight between now and the winter solstice in late December.

&&

.CTP WATCHES/WARNINGS/ADVISORIES...
None.
