AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE STATE COLLEGE PA
1148 AM EST TUE FEB 8 2011

.SYNOPSIS...
LOW PRESSURE WILL RAPIDLY INTENSIFY EAST OF THE NEW ENGLAND
BENCHMARK TODAY...SETTING UP A GUSTY AND VERY COLD NORTHWEST FLOW
OVER THE COMMONWEALTH. A POTENT UPPER LEVEL TROUGH WILL CROSS
THROUGH THE REGION THIS AFTERNOON BRINGING FREQUENT SNOW SHOWERS
ACROSS THE NORTHWEST HALF OF THE STATE. HIGH PRESSURE WILL REMAIN
IN CONTROL THROUGH MID WEEK WITH BELOW NORMAL TEMPERATURES AND
GENERALLY DRY WEATHER.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
FAIRLY STRONG LOW TO MID LEVEL COLD ADVECTION WILL CONTINUE THIS
AFTERNOON...LEADING TO SLOWLY FALLING TEMPS AT ALL SFC SITES IN
CENTRAL PENN.

A SHARP MID LEVEL TROUGH WITH CORE TEMPS OF -25 TO -27C WILL CROSS
THE REGION AND HELP TO ACCENTUATE THE BANDS OF SNOW SHOWERS
ALREADY PEPPERING THE RADAR SCOPE. RELUCTANTLY ALLOWED THE WINTER
WEATHER ADVISORY FOR THE LAUREL TO EXPIRE AT 15Z /BASED ON
ANTICIPATED ADDITIONAL WIDESPREAD ACCUMS OF LESS THAN 3 INCHES FOR
THE REST OF TODAY/. TRAVEL CONDITIONS AND VSBYS /DUE TO AREAS OF
BLOWING SNOW/ MIGHT NOT BE MUCH BETTER THIS AFTERNOON THOUGH.

CLOUD-LAYER TEMPS SMACK IN THE MIDDLE OF THE RANGE FAVORABLE FOR
DENDRITIC GROWTH /-12 TO -18C/ WILL HELP CONTRIBUTE TO ADDITIONAL
ACCUMULATION OF A COATING TO 2 INCHES ACROSS THE LAURELS AND NW
MTNS...WITH GENERALLY 0.5 INCH OR LESS THROUGH THE CENTRAL RIDGE
AND VALLEY REGION FROM PERSISTENT FLURRIES...AND A FEW BRIEFLY
HEAVIER SNOW SHOWERS. THE INCREASING NW WINDS WITH GUSTS OF 35-45
MPH...WILL CREATE BLOWING AND DRIFTING OF THE FLUFFY FRESH SNOW
AND LOCALIZED VSBYS OF 1/4 MILE OR LESS IN MEANDERING/NARROW BANDS
OF HEAVIER SNOW SHOWERS.

TEMPS WILL CONTINUE TO SLOWLY FALL THROUGH THE REST OF TODAY WITH
TEMPS AT DUSK NEAR 10F ACROSS THE NW MTNS...UPPER TEENS IN THE
CENTRAL VALLEYS...AND IN THE LOWER TO MID 20S ACROSS THE LOWER
SUSQ REGION.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM WEDNESDAY/...
ANY LINGERING SNOW SHOWER ACTIVITY WILL DIMINISH BY THIS EVE. SFC
RIDGE WILL EXTEND ESEWD ACRS THE CENTRAL APPLCHNS INTO THE SRN
MID ATLC FROM 1040MB HIGH DROPPING SWD ACRS THE NCENTRAL PLAINS
STATES. THIS WILL ALLOW WINDS TO GRADUALLY WEAKEN LATE TONIGHT
INTO EARLY WED AM. THE LOCAL AREA WILL BE ON THE NRN PERIPHERY OF
THE RIDGE AXIS AND EXPECT A 5-10KT BACKING WIND TO BE MAINTAINED
OVR MOST OF THE REGION. THE MAIN FOCUS FOR THE OVERNIGHT PD IS ON
POTENTIAL ADVY CRITERIA /-15F/ WIND CHILLS OVR THE N/W MTNS..WHERE
FCST LOWS ARE TO BOTTOM OUT IN THE LOW SINGLE DIGITS. WILL
HIGHLIGHT THIS THREAT IN THE HWO.

&&

.LONG TERM /WEDNESDAY THROUGH TUESDAY/...
HIGH PRESSURE WILL RIDGE INTO PA FROM THE WEST ON WEDNESDAY INTO
THURSDAY. A REINFORCING SHOT OF COLD AIR ACCOMPANIED BY A PERIOD
OR TWO OF LIGHT SNOW COULD TRACK ACROSS THE STATE LATE WED/WED
NIGHT...ALTHOUGH LATEST GUIDANCE HALTS THE COLDEST AIR NORTH OF
THE FINGERLAKES REGION. LOWS WED NIGHTS IN THE SINGLE DIGITS
NORTH...TO TEENS SOUTH. HIGHS WILL BE JUST 20-30F BOTH WED AND
THU.

A SPLIT FLOW PATTERN WILL PERSIST FOR MUCH OF THIS PERIOD... WITH
POTENTIAL MID ATLANTIC COASTAL CYCLOGENESIS APPEARING TO BE TOO
FAR TO THE SOUTH AND EAST TO HAVE ANY IMPACT ON SENSIBLE WEATHER
OVER CENTRAL PENNSYLVANIA OVER THE NEXT SEVERAL DAYS.

CONSIDERABLE UNCERTAINTY HAS BEEN EVIDENT IN THE EXTENDED OUTLOOK
FROM NEXT WEEKEND AND BEYOND. WHAT APPEARS CERTAIN IS A PERIOD OF
ZONAL FLOW WILL REACH THE OHIO VALLEY AND GREAT LAKES PROVIDING AT
LEAST SOME MODERATION. BEYOND THAT...GEFS MEAN SOLUTIONS AND
DETERMINISTIC ECMWF TRY TO REDEVELOP A MEAN TROF OVER THE EASTERN
THIRD OF THE CONUS BY NEXT WEDNESDAY. GIVEN SUCH UNCERTAINTY...
OPTED TO MAINTAIN CONSISTENCY IN DAYS 5-8 AT THIS TIME.

&&

.AVIATION /16Z TUESDAY THROUGH SATURDAY/...
NWLY FLOW WILL CONT IFR/MVFR CIGS AND MAINLY IFR VSBYS IN -SHSN
AT JST AND BFD THROUGH THIS AFTERNOON. PERIODS OF MVFR CIGS AND
VSBYS WILL AFFECT THE CENTRAL RIDGE AND VALLEY TAF SITES /WITH
CONDITIONS BRIEFLY DIPPING TO IFR/. LOW PRESSURE IS XPCTD TO
RAPIDLY DEEPEN OFFSHORE NEW ENGLAND WHICH WILL CREATE A TIGHT PRES
GRAD OVER PA THIS AFTERNOON. MDL SOUNDING DATA SUPPORTS WNW WNDS
15-20KTS WITH GUSTS BTWN 25-35KTS THROUGH THE DAYTIME HOURS. HIGH
PRES BUILDING IN TONIGHT WILL RELAX THE WINDS TO 5-10KTS.

OUTLOOK...
WED-THU...MVFR IN SCT SHSN NW...OTHERWISE VFR.
FRI...VFR...BCMG MVFR WEST LATE.
SAT...MVFR/IFR IN SHSN WEST...MAINLY VFR EAST.
