Area Forecast Discussion
National Weather Service State College PA
208 PM EDT Fri Mar 31 2023

.SYNOPSIS...
A wet end to March for most as rain spreads west to east across
central PA from midday through the evening and into tonight.
Not an April Fool's joke: High winds and severe thunderstorms
could knock down trees and cause numerous power outages on
Saturday. The active weather will be driven in part by a large
temperature swing on the order of 30-40 degrees between Saturday
afternoon and Saturday night. Sunday will be the pick of the
weekend with decreasing wind and plenty of sunshine. Warmth
will build through early next week with temperatures surging
well above normal and feeling very spring-like.

&&

.NEAR TERM /THROUGH TONIGHT/...
Thickening mid cloud deck in the process of overspreading CPA
early this morning - a sign that warm advection pattern is well
underway. As mentioned last night, radar picking up plenty of
returns aloft drifting across north central PA, but very dry
air in the low levels (>10C Td depressions) causing most precip
(would be in the form of snow) to evaporate before reaching the
ground.

So a dry start to the last day of March before rain expands
across the western and central Alleghenies from late morning
through the evening. Max 12hr QPF ending 00Z Sat is fcst across
the NW Alleghenies with amounts in the 0.25-0.50" range. We
don't expect much rain to fall to the southeast of I-81 thru
00Z. Max temps rebound +5 to +15F from yesterday with highs in
the upper 40s over the northeast mtns to around 60F in the LSV.

Periods of rain continue tonight with some heavier downpours and
rumbles of thunder possible after midnight into early Saturday
morning. Big upward swing for min temps in the mid 40s-50s or
+15-25F warmer than last night and equally warmer than climo. We
also anticipate a non diurnal/rising trend overnight.

&&

.SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/...
Saturday (first day of trout season in Pennsylvania) looks very
windy with a dual severe t-storm threat and non-tstm high wind
hazard in play.

SPC has upgraded the convective outlook from level 1 to 2 out of
5 (Slight risk) given notable signal for a strongly forced low
topped line or cluster to race across at least part of the area
during the midday to afternoon timeframe. The 00Z 3km NAM and
HRRR depict the timing and evolution of this feature quite well.
Early morning rain should exit the eastern zones, followed by
clouds breaks allowing for very deep BL mixing and steep lapse
rates beneath the dry slot. This will be favorable for downward
momentum transfer of very strong mean flow >50kts 0-6km which
could result in a number of sfc wind gust of similar magnitude.
Despite lack of tree foliage, this scenario would likely result
in significant tree damage and potentially lead to numerous
power outages. Based on the latest hires guidance, it appears
the threat is maximized over the northern half of central PA.

In addition to the convective risk, a formidable and potentially
damaging non-tstm high wind event remains possible in the Saturday
afternoon-evening timeframe. Any preceding low topped convective
line should only enhance this risk given larger pressure rises
over a short duration. No change to the high wind watch for this
cycle with max gusts 55-60mph still focused over the Laurel
Highlands and south central Alleghenies. We would anticipate
making the call on high wind warning and wind advisory within
the next forecast cycle on the dayshift today. A wind advisory
is a virtual slam dunk at this point for most if not all of the
CWA.

Much colder, post-frontal WNW flow will deliver a rain to snow
shower transition across the western Alleghenies later Sat night
with a minor accumulation <1 inch possible by Sunday morning.

Building high pressure will bring an end to any lingering snow
showers across the western high terrain early Sunday, with
clearing skies and a noticeably cooler and drier airmass briefly
returning to close out the first weekend of April.

&&

.LONG TERM /MONDAY THROUGH FRIDAY/...
All guidance points to fair weather Monday, as high pressure
passes off the Mid Atlantic coast and an ensuing southwest flow
advects much warmer air into the state. A weak shortwave
passing north of the region should push a dying cold front into
PA Monday night, which is likely to stall over the region into
Tuesday. Low level convergence and a plume of anomalous pwats
along the front should support a fair amount of cloud cover and
the chance of showers esp NW Monday night and Tuesday. However,
lack of large scale forcing supports only limited POPs.

All medium range guidance supports very warm conditions midweek,
peaking on Wednesday, as the stalled front lifts north of the
state ahead of an upstream trough. Diurnal heating, combined
with falling heights ahead of the trough, should translate to an
increased chance of showers Wednesday during the day,
especially over the W Mtns. Ensemble mean 850mb temps around 11C
could support temps pushing 80F in southern valleys if there's
enough sunshine.

Model spread and forecast uncertainty increase the second half
of next week regarding the timing of the upstream trough.
However, all guidance tracks the associated surface low well north
of PA, with a trailing cold front and potential showers coming
through in the Wednesday night to Thursday AM time frame. Temps
slip back toward seasonal norms by Friday.

&&

.AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...
VFR conditions will prevail for most of the area through Friday
morning with light and variable winds. The exception is the
lower Susq valley (MDT and LNS) where MVFR cigs are likely this
morning through early afternoon as coastal moisture advects
northward beneath a low level inversion.

Clouds increase and lower on Friday with cig restrictions
developing over northern and western airfields late morning and
early afternoon. The earliest raindrops could fall in BFD by
14-15z, with rain subsequently overspreading the northern and
western portion of central PA through 19z. Several rounds of
rainfall are expected from Fri PM through Sat morning. LLWS will
develop across northern and western airfields Fri evening as SW
flow at 2kft AGL increases to 40-55 kts.

After widespread showers and low cigs associated with a cold
front early Saturday, a dry slot moving over the area will bring
mostly VFR conditions from late morning through afternoon.
Saturday will be windy with widespread wind gusts in the 40s kts
and 50 kt wind gusts possible in the Laurel Highlands and
central Alleghenies. A secondary cold front and the primary
upper trough will swing through by mid- late afternoon Saturday,
likely bringing a line of low topped convection. The convection
may locally enhance gusty winds, producing 50+ kt wind gusts at
the surface. Scattered snow showers are possible in the northern
mountains behind the cold front.

Outlook...

Sun-Mon...No sig wx expected.

Mon night - Tue...Cig and vsby restrictions possible in SHRA,
especially northern/western airfields

.CLIMATE...
With the last day of March upon us, here is a quick look at
monthly temperature, precipitation, and snowfall totals at
Harrisburg and Williamsport along with departure from normal.

Harrisburg through 3/30:
Avg. Temp = 42.9F (+1.3F)
