AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE STATE COLLEGE PA
731 PM EST WED JAN 22 2014

.SYNOPSIS...

A DEEP UPPER LEVEL TROUGH WILL REMAIN OVER THE NORTHEAST THROUGH
THE MIDDLE OF NEXT WEEK. A STRONG DISTURBANCE WILL TRACK ACROSS
THE COMMONWEALTH ON THURSDAY BRINGING SNOW SHOWERS AND A FEW
HEAVIER AFTERNOON SQUALLS. ADDITIONAL ALBERTA CLIPPERS ROUNDING
THE SOUTHERN EDGE OF THE LARGE UPPER TROUGH WILL TRACK SOUTHEAST
ACROSS PENNSYLVANIA EVERY COUPLE OF DAYS.

&&

.NEAR TERM /UNTIL 7 AM THURSDAY MORNING/...

CLOUDS ARE ALREADY MOVING INTO EXTREME WESTERN AREAS AND WILL
RAPIDLY SPREAD EASTWARD TONIGHT. STILL CLEAR IN THE EAST SO THERE
COULD BE SEVERAL HOURS OF GOOD RADIATIONAL COOLING IN THE
SOUTHEAST...ESPECIALLY IN THE DEEPER FRESH SNOW LANCASTER AND YORK
COUNTIES. IN CENTRAL AND WESTERN AREAS TEMPERATURES SHOULD NOT
FALL TO FAR AND SHOULD BEGIN TO SLOWLY RISE LATER TONIGHT.

THE SURGE OF CLOUDS AND COMING SNOW SHOWERS IN THE WEST IS
ASSOCIATED WITH A CLOSED 500 HPA LOW OVER THE NORTHERN LAKES...A
STRONG IF SHORT-WAVE WHICH IS PUSHING OUR WAY...WITH A BRIEF SURGE
OF SLIGHTLY WARMER AIR AHEAD OF IT.

THE 4KM NAM...RAP AND SREF ALL SUGGEST SNOW SHOWERS DEVELOP OVER
WESTERN AREAS OVERNIGHT. AN INCH OR SO OF ACCUMULATION IS POSSIBLE
BEFORE SUNRISE IN WESTERN AREAS.

OVERNIGHT LOWS SHOULD BE MAINLY IN THE SINGLE DIGITS AND ONLY
ISOLATED SUB-ZERO READINGS. MOST LOCATIONS SHOULD SEE THE
OVERNIGHT LOWS OVERNIGHT AND BEFORE SUNRISE. THIS MAY NOT HOLD
TRUE IN THE EXTREME SOUTHEAST.

SOME COLD IMPACTS OF NOTE...VISUAL IMAGERY SHOWED CONSIDERABLE ICE
OVER LAKE ERIE AGAIN...RIVER ICE IN NORTHWESTERN PA IS AGAIN VISIBLE
TOO. WE HAVE REPORTS OF FRAZZLE PANS IN THE LOWER SUSQUEHANNA NOW
SO ICE FORMATION IS LIKELY TO BEGIN WITH THE COMING REINFORCING COLD
SURGE.

&&

.SHORT TERM /7 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/...

IT SHOULD BE A NOTICEABLY WARMER DAY THURSDAY OVER THE EASTERN
2/3 OF THE REGION RELATIVE TO WEDNESDAY AS MODESTLY WARMER AIR
MOVES INTO THE REGION AHEAD OF THE SECOND ARCTIC SURGE HEADING
OUR WAY.

SNOW AND SNOW SQUALL ACTIVITY SHOULD BE ON ON THE INCREASE IN
WESTERN AREAS WITH A GOOD POSSIBILITY OF ON-GOING SNOW SHOWERS AS
THE ARCTIC FRONT WILL BE ON THE DOOR STEP. SREF AND HIGHER
RESOLUTION MODELS SHOW SHOWERS AND SQUALL IN WESTERN PA THURSDAY
AS THE -20 TO -22C AIR AT 850 HPA MOVES OVER THE REGION.

MOST SREF PLUMES SHOW SNOW BY MIDDAY OVER MOST OF THE REGION.
HIGHEST CHANCE OF ACCUMULATING SNOW IS TO THE WEST AND IN THE
HIGHER ELEVATIONS. SNOW IN THE EAST WILL COME LATER IN THE DAY.

SOME RELATIVELY GOOD TTI VALUES IN THE 30-38 RANGE IN NORTHWESTERN
PA TOMORROW AFTERNOON AND EVENING. SHOULD ENHANCE CONVECTIVE SNOW
SHOWER/SQUALL POTENTIAL. MODELS ALSO SO 1-2 SIGMA ABOVE NORMAL
WINDS IN THE AFTERNOON AND EVENING.

THE STRONG WINDS ALONG AND BEHIND THE SURGE OF ARCTIC AIR IS
TRIGGERING WIND CHILL ISSUES IN OUR FORECAST GRIDS THURSDAY
AFTERNOON INTO EARLY FRIDAY.

&&

.LONG TERM /FRIDAY THROUGH WEDNESDAY/...

MED RANGE GUIDANCE CONTINUES TO INDICATE A SPLIT IN THE POLAR
VORTEX PERSISTING FRIDAY THRU TUESDAY...WITH ONE PIECE LINGERING
JUST SOUTH OF HUDSON BAY. NEGATIVE HEIGHT AND THERMAL PROFILES IN
THE GEFS AND EC ENSEMBLE DATA SHOULD LEAD TO A HIGH CONFIDENCE
FCST OF WELL BELOW NORMAL TEMPS THRU EARLY NEXT WEEK. AS THE LARGE
QUASI STATIONARY LOW ROTATES OVER THE BAY...AND MOVES EVER SLOWLY
EASTWARD...ALBERTA CLIPPERS ROTATING AROUND THE SOUTHERN PERIPHERY
OF THE UPPER LOW WILL BRING THE CHANCE OF LIGHT SNOW EVERY COUPLE
OF DAYS. GOOD AGREEMENT AMONG MED RANGE MD LS THAT ONE CLIPPER WILL
AFFECT CENTRAL PA ON SATURDAY AND ANOTHER SUN NI TE/MONDAY. BEHIND
EACH CLIPPER...A REINFORCING SHOT OF ARCTIC AIR WILL SPREAD SOUTH
ACROSS THE REGION. EARLY INDICATIONS ARE OUR LONG STRETCH OF
FRIGID WX COULD COME TO AN END BY LATE NEXT WEEK...WHEN GEFS AND
EC ENSEMBLE DATA BOTH INDICATE WEST COAST RIDGE BREAKS
DOWN...ALLOWING MODIFIED PACIFIC AIR TO WORK IT/S WAY EAST TOWARD
PA. WITH STRONG GUSTY WINDS AND AN EVER PRESENT ARCTIC AIR MASS
THERE SHOULD BE QUITE A FEW PERIODS OF LOW WIND CHILLS...GENERALLY
OVER THE ELEVATED REGIONS...THURSDAY...SATURDAY AND EARLY NEXT
WEEK. HAVE MENTIONED CONDITIONS IN HWO...BUT WILL HOLD OFF ON ANY
HIGHLIGHTS. THE STRONG PRESSURE GRADIENT COULD ALLOW FOR GUSTY
WINDS IN SOMERSET COUNTY SATURDAY AFTERNOON.

&&

.AVIATION /01Z THURSDAY THROUGH MONDAY/...
NEXT COLD FRONT WILL MOVE IN DURING THE DAY ON THU. EXPECT
POOR CONDITIONS ACROSS THE MOUNTAINS WITH SNOW SHOWERS.

IMPROVING CONDITIONS EXPECTED BY LATE MORNING ON FRIDAY...AS
WINDS SHIFT TO THE SW. IT WILL BE WINDY OUT.

HOWEVER...ANOTHER SHOT OF COLD AIR FOR SAT...AS A COLD FRONT
MOVES ACROSS THE AREA WITH MORE SNOW SHOWERS AND GUSTY WINDS.

WINDS SHIFT BACK TO THE SW ON SUNDAY...BEFORE ANOTHER COLD
FRONT MOVES IN LATE SUNDAY NIGHT INTO MONDAY.

OUTLOOK...

FRI...VFR/MVFR. NO SIG WX.
SAT...MVFR-IFR IN AREAS OF -SHSN.
SUN...MAINLY VFR.
MON...MVFR-IFR IN AREAS OF -SNSN.

.CTP WATCHES/WARNINGS/ADVISORIES...
