Area Forecast Discussion
National Weather Service State College PA
411 AM EDT Tue Mar 20 2018

.SYNOPSIS...

Big changes to our weather on the way as a storm system will
affect the area for the first day of Spring tomorrow. The storm
will primarily affect the southern half of the area. It will
initially bring a mixture of rain and snow but by Tuesday night
and Wednesday primarily snow will fall and significant
accumulations are possible across southern Pennsylvania. Cooler
than average temperatures will dominate the pattern through the
end of the week, with the next opportunity for precipitation
coming this weekend.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...

Near term in good shape with increasing clouds tonight. Latest
HRRR/NAM12 shows precip shield moving towards CWA in the pre
dawn hours. Latest HREF2 lags by a couple of hours, bringing
precip shield into Laurels and South Central mountains after
12z. Siding with the earlier HRRR/NAM12 at this time into the
Laurels. Temperatures should be cold enough for snow across the
south, but QPF should be light enough to limit much in the way
of accumulation initially.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH WEDNESDAY NIGHT/...

Complicated storm system with snow and potentially some mixed
precipitation across southern half of CWA. Initially the
temperature profile and intensities of the precip suggest snow
will have trouble sticking in valleys and banding will determine
where accums are more efficient. Higher elevations will see
more accumulating snow. Temperature profiles cool dynamically
and this has become more pronounced in the 18z and early look at
00z Tue NAM12 run. This brings a better chance of accumulating
snow for valley locales as well. Snow will continue into
evening and Wednesday and Winter Storm Watch remains in effect
for southern zones for the long duration of potential snow fall.
Kept the Watch in place to allow mid shift opportunity to assess
latest numbers as we are approaching 12- and 24- hour Warning
criteria and trend from 00z runs and CAMs will provide critical
information.

Besides the typical March complications with snow accumulations
(moderate to heavy snowfall rates needed to offset melting as
snow falls due to higher sun angles), the duration nature of
this system will make achieving Warning criteria difficult, with
only 30-40% probs of 6" or more in a 12 hour period in the Watch
area currently, and 30-40% probs of 8" or more in a 12 hour
period from Tuesday morning through Wednesday afternoon. Latest
guidance from the 12z Mon cycle has ramped up QPF/snow totals
over southern PA, but this may be in part due to an overzealous
NAM package. The current 90th percentile snowfall for Somerset
County is in the ridiculoso range (not to be mentioned here),
far beyond anything we are reasonably forecasting, so am hoping
that the addition of global model members into the pdf suite
will yield greater confidence and less spread probabilistically
for the overnight forecast tweaks.

By daybreak Wednesday the storm is expected to be reorganizing
off the Mid Atlantic before tracking off south of Nantucket
island. The upper trough/low will keep some light precip
lingering Tuesday night and Wednesday morning. An additional
coating of snow is possible as surface temperatures chill down
into the 20s in most areas Tuesday night.
&&

.LONG TERM /THURSDAY THROUGH MONDAY/...

By later Wednesday into early Thursday...the storm will slowly
lift away from our area. An upper level low will drop southeast
late Thurday into Friday. This will likely bring more clouds
back ito the area...with a chance of some snow showers.

A complex pattern for the upcoming weekend into early next
week will prevail. Central PA will likely be between a
developing storm off the coast...and on the edge of warm
advection from the central plains. Thus much of the time it
should be dry.

Main changes made was to adjust POPS down some for the weekend
into next week...mainly to fit a little better with others. I did
not want to change too much...given the large variation in model
solutions.

The other change was to adjust temperatures down after Thursday
into the weekend...given northerly flow and source region of the
airmass.

&&

.AVIATION /08Z TUESDAY THROUGH SATURDAY/...

Patchy precipitation starting to work into Somerset County.

Main leading edge to the snow is further south...between 30 to
100 miles from the PA border.

Expect the snow to edge northward this morning...with perhaps
some sleet at times. North flow of dry air will tend to slow
the northward advance of the snow. There will be a tight
gradient between VFR conditions across the far north later
today...and IFR to MVFR condtions further south.

Not much improvement to later Wednesday or early Thursday...as
some snow will linger.

Outlook...

Tue night and Wed...Snow and restrictions continue. Some
improvement late day.

Thu...No sig wx expected.

Fri-Sat...A few snow showers possible.

&&

.CLIMATE...

The Spring (Vernal) Equinox will be at 12:15 PM on Tuesday,
March 20. Sunrise in State College, PA will be 7:14 AM and
sunset at 7:23 PM, for a total day length of just over 12
hours.

While it will be spring on the calender today...a look outside
will be more like winter. One may have to wait until late in
the month to see a touch of spring like temperatures.
