Area Forecast Discussion
National Weather Service State College PA
1229 PM EDT Sun Mar 16 2025

.SYNOPSIS...
* A strong cold front will push across Central PA this
  afternoon, producing a soaking rain and some stronger to
  severe thunderstorms, especially across the Western third of
  PA.
* One cooler day on Monday will be followed by a warm up as
  ridging moves in from the west and settles overhead for mid-
  week.

&&

.NEAR TERM /UNTIL 7 PM THIS EVENING/...
Convective and shear parameter will begin phasing across our
Western zones between 17-18Z as a pronounced dry slots spreads
NNE across that area and a potent sfc cold front (now over
Central Ohio) pushes east.

After our waves of stratiform rain (briefly moderate to heavy
in intensity) shift east of the Susq Valley during the early to
mid afternoon hours, 1-2 lines of strong to severe tsra are
expected to progress east across the CWA. The best, enhanced
mesoscale forcing beneath the entrance region of a potent, nwd
moving upper level jetlet should be focused across the western
third to half of our CWA (within SPC's DY 1 Enhanced Convective
Risk area).

00Z and 12Z HREF are consistent in indicating that the best
instability/convective cluster/s will move across the Laurels
and SCent Mtns during the early to mid afternoon hours along a
developing prefrontal trough, with a secondary narrow line of
strong to severe TSRA a bit further west along the Cfront.

0-1KM SREH will max out around 400 m2/s2 along the prefrontal
trough (and its intersection with the cooler/OVC skies to the
east with LLVL Serly flow). The best combination of llvl
shear/instability will potentially be over the Scent Mtns near
the I-81 corridor between 18-19Z before slowly weakening further
east.

Vsbys have dramatically improved (to above 3SM) across the
areas previously covered by a dense fog advisory across the
Ncent Mtns and Western Poconos as T/Td spreads have grown to
several deg F or more.

Prev...
Wind is currently gusting into the l-m30s in places despite the
seemingly stable layer hosting the stratus/low topped convection
racing north.

The wind fields in model soundings are eye-poppingly high with
a big curved hodograph. The first worry is for the gradient wind
mixing down through the thin/shallow stable layer in place.
Probabilities of 45+MPH gusts are 90+% in the N and SE through
the day (mainly morning N and mainly late AM til late aftn SE).
Thinking right now is that it will won't take much mixing,
either through terrain interaction/enhancement, or even the
shallowest of convection. Going to post a wind advy for the nrn
tier, but on the fence for the Laurels and SErn few zones. These
areas are also most likely to get some clearing and deeper
mixing, even before any SHRA/TSRA move in.

Speaking of SHRA/TSRA...there are SHRA not too far to the W and
should make some light rain over the wrn Cos shortly, certainly
before sunrise. After a wave aloft rolls through early this
morning, there should be a short lull, but very short as the
extremely strong winds from 5kft up will be whipping things
along. Any openings in the clouds could destabilize the llvls.
Lapse rates aloft should allow for thunder chc across most of
the area today. But, it is the severe threat that has just been
increased in the latest SPC Day1 severe weather outlook which is
most concerning. The strong wind fields and possibility of even
mixing into the 3-5kft range should allow shear/SRH & EHIs to
become realized. MU CAPE on the HREF guidance pokes some
500-1000J/kg numbers into the srn tier in the aftn. The outlook
now has the wrn half or so in a SLGT risk with a 5% Tor risk -
which is higher than we see here in PA on about 360 days/year.
BUT...It will be the ability to scour out or poke down through
the stable layer that will determine the realization of this
threat. We will certainly increase our messaging on the severe
threats. Thinking locally is that there also may be an equal
tor risk all across our srn tier than what is presented in the
SPC guidance early this morning. Timing for strongest convection
is better in the E than W. Will continue with only mentions of
TS (30pct) for most of the CWA as the potentially stubborn low
clouds and llvl stability could squelch TS. But, the instability
aloft is there, and it seems like a good idea to mention it all
over, esp in light of the SPC outlook of SVR.

Heavy rainfall continues to be a small but non-zero concern,
especially in places where the lowest FFG and orographic lift
are juxtaposed. This is mainly over the NE third of the CWA.
But, minor/urban and small stream flooding are still a concern
in the rest of the CWA due to the (much) higher than normal
PWATs and the possibility of training or at least repeated shots
of rain.

&&

.SHORT TERM /7 PM THIS EVENING THROUGH 6 PM MONDAY/...
SHRA/TSRA along the front will drag their feet over the SE
(what's new there?) this evening and early tonight. This
certainly seems to increase the risk of flooding there where
training could push streams out of their banks. The west will
experience some strong CAA tonight with 8h temps falling from
+11C Sun morning down to -6 t0 -10C by sunrise Monday. This
change will be quite shocking, and the SHRA lingering in the
wrap around over the NW and SW will probably turn to SHSN. The
moisture there dries up before noon Mon. So, no worries for
anything more than a tiny bit of slush building up. But, the
very warm/rainy wx early tonight and the sharp drop in temps
could allow road temps to drop far enough to make a bridge deck
or two icy over the NW where they will be the only place to dip
below freezing. Mins tonight will be in the u20s in Warren, but
around 50F in Lancaster. As sunshine increases on Monday, some
4-6F temp increase is forecast for the aftn. But, temps may hold
steady or even fall a little bit at first, esp in the SE half of
the CWA.

&&

.LONG TERM /MONDAY NIGHT THROUGH SATURDAY/...
System lifting east of the area Monday will give the area
a dry day on Tuesday. Another deep low moving northeast from
the Rockies will bring another warm up by mid week.

This system will bring some showers and perhaps a storm to
the region by Thursday. Moisture more limited with this
system, thus widespread heavy rain and strong storms not as
likely as our current system today.

After this low moves northeast of our area, models show the
large scale ridge forming back over the western states late
in the week. This would support a return to cold weather as
we head into Spring.

&&

.AVIATION /18Z SUNDAY THROUGH FRIDAY/...
Low CIGS will persist through much of the day, though there
could be some breaks in the clouds across the area in the
afternoon. MVFR ceilings are expected across much of the region,
with IFR expected at MDT and LNS into the morning. Wind gusts
will also continue to increase through the morning with much of
the area likely seeing gusts of 30 to 40 knots by the afternoon.

LLWS will prevail across the airspace into the afternoon with a
50 to 60+ knot low-level jet traversing the region. As surface
wind gusts increase during the morning the LLWS threat will be
somewhat mitigated, but if gusts do not get as high as
anticipated we may have to extend the mentions of shear in the
TAFs.

Showers will continue to push eastward through the rest of the
morning. These initial showers should be fairly light.
Attention then turns to a line of thunderstorms that is expected
to move through during the afternoon and early evening ahead of
a cold front. The line of storms will approach BFD and JST
around 16-17Z and will quickly progress eastward, reaching the
eastern airfields by 21Z. Models have been trending towards a
more unstable environment ahead of these storms, and the
stronger storms will be capable of producing wind gusts greater
than 50 knots and perhaps even an isolated tornado.

Behind these storms, all areas except MDT and LNS are expected
to experience a period of VFR conditions. As winds turn to the
west behind the cold front, MVFR ceilings will redevelop at BFD
and JST.

Outlook...

Mon...Windy and colder with clearing skies.

Tue...VFR with lighter winds.

Wed...VFR.

Thu...Showers overspreading the area from west to east.
