Regional Weather Summary
National Weather Service State College PA
443 PM EDT Mon Sep 15 2025

High pressure will keep mainly dry weather across the keystone
state this week. Some showers will be possible across the
southeast portion of the state Tuesday into Wednesday night.

The next chance of widespread showers will be late in the
upcoming weekend.

Overall high temperatures the next several days will be in the in
the 70s to low 80s. Lows will range from the 40s and 50s across
the mountains to the lower 60s across the southeast. The coolest
day will be Wednesday, and the warmest day will be Friday.

The ongoing dry spell and 30 to 60 day rainfall deficit will
continue across most of Pennsylvania during the last week of
astronomical summer. Rainfall across the southeast corner of the
Keystone state will be less an inch by the time the rain tapers
off late Wednesday.

The northwest half of Pennsylvania is projected to stay dry with
no relief in the abnormally dry to moderate drought conditions.

Area Forecast Discussion

117 AM EDT Tue Sep 16 2025

.SYNOPSIS...
* Cloud coverage gradually increases overnight with valley fog
potential across the northern tier tonight.
* Light rain possible across southeastern Pennsylvania Tuesday
through Wednesday.
* Dry conditions prevail on Thursday and through the first half
of the weekend.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
High clouds emanating from a neat-looking low pressure system
off the coast of the Outer Banks tonight continue to drift north
into Pennsylvania this evening. Despite the high clouds, high
pressure will produce light/calm winds and another night with
ideal radiational cooling and valley fog potential across the
northern tier. Low temperatures overnight into Tuesday morning
are expected to be above climatological averages, ranging from
the upper 40s across NW PA to the upper 50s across SE PA.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH WEDNESDAY NIGHT/...
Low pressure will lift slowly northward from the Outer Banks
and VA Tidewater off the Mid-Atlantic coast through the middle
of the week. Latest model guidance continues to indicate the
best chance for rain over the southeast zones (southeast of
I-81/78) where a moist/upslope easterly low-level flow will
bring better moisture returns. Further north/west, precipitation
is less likely; however, aforementioned easterly flow will
allow for more expansive cloud coverage and cooler temperatures
for much of the forecast area. Most recent QPF has tapered back
ever so slightly, keeping the southern reaches of Adams/York and
much of Lancaster County above 0.10" rainfall over a fairly
tight gradient. Precipitation Wednesday night is expected to
gradually move east of the area as the coastal low begins to
push further offshore.

&&

.LONG TERM /THURSDAY THROUGH MONDAY/...
A brief spell of dry conditions is once again expected in the
wake of the coastal low, with moderate-to-high confidence in dry
conditions beginning on Thursday and continuing through Saturday.
Recent model guidance has slightly slowed down with respect to
the low pressure system in the Midwest with a fair amount of
uncertainty between deterministic model guidance. Given these
changes, have decided to roll with NBM through Monday, with the
best chances of precipitation coming after sunrise on Sunday and
into the end of the long-term period.

&&

.AVIATION /05Z TUESDAY THROUGH SATURDAY/...
Widespread VFR conditions are expected overnight with varying
amounts of high cloud cover. Light winds and a lack of low
clouds will allow for valley fog formation into the early
morning, but most guidance suggests all TAF sites will remain
VFR. That being said, there is around a 40% chance for BFD and
IPT to see a period of IFR or LIFR conditions after 09z before
the fog dissipates.

VFR conditions continue through the day with isolated showers
possible in southeast PA. Clouds will gradually thicken, but VFR
conditions will continue through 12Z Wednesday. The only
exception may be at LNS where easterly flow could lead to MVFR
ceilings developing after 06Z. Valley fog across northern PA
does not appear as likely as it has the past few nights.

Outlook...

Wed-Thu...Generally VFR, some SHRA possible (20-40%) SE PA.

Fri-Sat...VFR with AM valley fog.

&&

.CLIMATE...
Astronomical fall officially begins with the autumnal equinox
on Monday, September 22, 2025 @ 2:19 p.m. EDT. The Autumn 2025
season will last 89 days, 20 hours, and 43 minutes. Daylight
saving time will end just after Halloween with clocks falling
back at 2 a.m. Sunday, November 2, 2025.

&&

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