Regional Weather Summary
National Weather Service State College PA
511 AM EST Tue Nov 18 2025
A weak ridge of high pressure over the Commonwealth will bring a
brief period of clearing early today before clouds thicken up from
the west later this morning through the afternoon, well ahead of
low pressure located over Missouri at daybreak.
This weather feature will spread a shield of chilly, steady rain
across the southwestern third of Pennsylvania this afternoon and
evening. As the precipitation drifts north toward the Interstate
80 corridor this evening, the air will be cold enough to allow a
mixture of rain and wet snow to occur. There could be a light
coating of snow on the highest ridge tops of Central PA
overnight.
The precipitation will exit to the east and off the Mid Atlantic
Coast Wednesday morning, but light wind and leftover moisture will
lead to lingering low clouds through the day Wednesday.
High temperatures today will range from the upper 30s to near 40
across the northwest half of the state, to the mid and upper 40s
respectively across the Lower Susquehanna Valley and Southeastern
PA. Low temperatures early Wednesday will be in the mid to upper
20s over the Northern Tier Counties and in the 30s across the
remainder of Central and Southern Pennsylvania.

Area Forecast Discussion
National Weather Service State College PA
Issued by National Weather Service Binghamton NY
216 PM EST Tue Nov 18 2025
.SYNOPSIS...
A quick moving system will bring rain to the area through
tonight, along with some elevation-driven wet snow. Mainly dry
weather returns for Wednesday and Thursday before another system
may bring some rain showers to the area Friday into Saturday. A
return to mainly dry weather arrives for the second half of the
weekend.
&&
.NEAR TERM /THROUGH TONIGHT/...
A fast moving low pressure system will move through the area
later today through tonight. Some warm air advection
precipitation ahead of this system has moved into parts of the
Commonwealth, but with dry air in place, much of this has been
virga or simply just very light precipitation. At some of the
higher elevations, temperatures are just cold enough at the
onset to start as some light snow, but any accumulations will be
minimal due to marginal temperatures and the light intensity of
the snow.
Tonight will be somewhat of a tricky forecast due to potential
wet bulbing allowing for temperatures to be a few degrees cooler
wherever there is steadier precipitation. This could allow for
rain to transition back to snow during the steadier
precipitation, especially at the higher elevations over east-
central PA near/along the I80 to US220 corridors in the 06-12Z
window. Snow accum is most likely on non-paved and elevated
surfaces with minimum temps hovering near to slightly above the
freezing mark. Precipitation should end/shift to the east by
7AM/12Z Wednesday.
&&
.SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/...
High pressure will bring mainly dry weather to the area for
Wednesday and Thursday, but lingering low level moisture will
likely keep clouds in place for most of the Commonwealth. Clouds
will be present area-wide on Thursday, but Wednesday may
actually have some sunshine for areas north of I-80. Seasonable
temperatures are expected with highs in the mid 40s to lower 50s
&&
.LONG TERM /FRIDAY THROUGH MONDAY/...
Another system will slide eastward from the Ohio Valley Friday
into Saturday, but there is a bit of uncertainty regarding how
far north the precipitation gets. Some guidance, such as the 12Z
ECMWF keeps most of the precipitation south of the Commonwealth,
while other guidance, such as the 12Z GFS, as the axis of
steadier precipitation moving right through PA. The NBM captures
this uncertainty relatively well with chance PoPs across most of
the area. After this system moves through, drier weather arrives
for the second half of the weekend into early next week.
&&
.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
Mainly VFR conditions are present to start the TAF period early
this afternoon, but ceilings and visbys will gradually lower by
the late afternoon/early evening as rain moves into the area.
IFR restrictions are expected, especially tonight. Rain will be
mixed with wet snow in the higher elevations. After the
rain/snow moves out of the area by Wednesday morning, there will
still likely be some IFR ceiling restrictions around through
most of the morning on Wednesday. Some gradual improvement is
expected by late Wednesday morning/early afternoon.
Outlook...
Wednesday afternoon through Thursday...Partial improvement in
conditions, but some lingering restrictions possible due to
lower clouds.
Friday through Saturday...Rain and associated restrictions
likely.
Sunday...Mainly VFR.
&&
.CTP WATCHES/WARNINGS/ADVISORIES...
None.
