Synopsis
High pressure will be nosing in from the west overnight and
Wednesday. Another potentially more significant storm system
will move into the region Thursday into Friday.

Near term until 6 am Wednesday morning
No changes to going forecast and no headlines added at this time
for Thursday storm.

Cold NW flow with light to occasional moderate intensity snow
showers over the NW and nc mountains late this evening. Minor
accums posted for these, especially the NW mountains where 1 to
locally 3 inches are possible. Nam12 capes of 40-60 j kg over
the northwest mountains will support a few heavier bursts of
snow shower activity overnight, but no squalls expected. Lows
tonight in the 20s will run a solid 5 to 10 degrees below
average for mid november.

A look at probabilistic ice forecasts indicates less than 40%
confidence in .25" or more ice amounts for the laurel highlands,
so have held off on a watch for now with new cycle incoming to
inform decision making overnight.

Short term 6 am Wednesday morning through 6 pm Wednesday
Wednesday will be dry and cold as a large area of high pressure
drifts east-northeast from the mid mississippi valley to the
new england states.

Highs will not reach freezing across the northern mountains,
and range to around 40 over the se.

Long term Wednesday night through Tuesday
As the ridge of high pressure moves east across the state
Wednesday night, strong radiational cooling of the ground will
occur (at least during the first half of of the night) with
winds staying light and variable and just a thin veil of
cirrostratus spreading northeast across much of the region.

Southeasterly low level flow will increase quickly after
midnight Wednesday night across the western mtns of the state as
the east west pressure gradient tightens. Clouds will also
lower thick to an altostratus deck across that part of the
state.

A thickening, mid-level cloud deck will then overspread the
entire CWA Thursday morning, followed by precipitation spreading
into somerset county after 4 am north to near the interstate 80
corridor by early afternoon. The upper low thurrsday is over the
memphis tn area with a surface low pressure area moving up the
west side of the appalachians and transferring energy to a new
low on the coast. Where this coastal low forms and tracks while
deepening makes all the difference in the thermal temperature
profile over central pa and what p-type is chosen. For now the
forecast is a mix of everything. The uncertainty over precip
type causes an uncertainty in specific amounts. What we are
certain of is that we will see wintry icy mix and feel confident
of the timing. There is the potential for borderline
warning advisory amounts of snow and ice particularly across the
higher elevations.

By Friday morning the upper low moves to near washington dc with
a low deepening on the coast moving quickly northeast. This
will change everything over to snow as cold air wraps in on the
backside of the low. Precipitation with end until lake effect
snow showers develop over the central and northern mountain
areas through Saturday and Sunday. Gusty west winds, along with
a decent amount of sunshine will prevale for southcentral
pa lower susq area.

Broad upper level long-wave trough will continue over the east
with some fast moving disturbances keeping chances for snow
showers across the north along with lake enhancement into early
next week.

Aviation 03z Wednesday through Sunday
Widespread mainly MVFR conditions will gradually improve over
central and eastern areas as a gusty and drier NW flow develops
in the wake of our departing storm system.

The usual areas of the higher elevations in the north and west
will remain subVFR into the evening.

Winds out of the wnw will increase to 10-15kt with gusts
20-25kts by later today. Expect lake effect and orographic snow
showers to continue sub-vfr conditions at kbfd kjst into
tonight.

Outlook
Wed... MVFR CIGS NW trendingVFR.

Thu-fri... MVFR ifr in snow or mixed precipitation.

Sat-sun... MainlyVFR. MVFR with snow showers nw.

Ctp watches warnings advisories
None.
