AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE STATE COLLEGE PA
410 PM EST SUN DEC 2 2007

.SYNOPSIS...
LOW PRESSURE OVER NRN MICHIGAN THIS AFTERNOON WILL CONTINUE THE
FEED OF DEEP MOISTURE ACROSS THE REGION THROUGH EARLY TONIGHT
BEFORE PUSHING A STRONG COLD FRONT ACROSS THE STATE LATE TONIGHT.

THE SHALLOW COLD AIRMASS ENTRENCHED ACROSS CENTRAL AND EASTERN
PENN WILL CONTINUE TO SUPPORT PERIODS OF LIGHT FREEZING RAIN/FZDZ
THROUGH THIS EVENING. A SEVERAL HOUR PERIOD OF HEAVIER RAIN...AN
EVEN A RUMBLE OF THUNDER WILL OCCUR TONIGHT ALONG AND IN ADVANCE
OF THE COLD FRONT.

MUCH COLDER AIR WILL SURGE EAST INTO THE COMMONWEALTH LATE TONIGHT
AND MONDAY ON THE BACKSIDE OF THE DEPARTING STORM SYSTEM...WITH
POTENTIALLY SIGNIFICANT LAKE EFFECT SNOWS DEVELOPING ACROSS THE
NORTHWESTERN MOUNTAINS AND THE LAUREL HIGHLANDS MONDAY AND MONDAY
NIGHT. WINDS WILL INCREASE DRAMATICALLY LATE TONIGHT AND MONDAY
SUSTAINED WINDS WILL BE INCREASING TO 20 TO 30 MPH ON MONDAY WITH
GUSTS BETWEEN 45 AND 50 MPH CONTINUING INTO MONDAY NIGHT.

THE SNOW SHOWERS WILL DECREASE IN COVERAGE EARLY TUESDAY AS A WEAK
RIDGE OF HIGH PRESSURE DRIFTS OVER THE STATE. QUICKLY FOLLOWING
THIS HIGH WILL BE AN ALBERTA CLIPPER TYPE SYSTEM THAT WILL SPREAD
A LIGHT SNOWFALL OVER THE REGION LATE TUESDAY NIGHT AND WEDNESDAY.

&&

.NEAR TERM /UNTIL 7 PM THIS EVENING/...
REGIONAL RADAR MOSAIC LOOP SHOWS POCKETS OF RAIN AND FREEZING RAIN
CONTINUING ACROSS MAINLY THE SOUTHERN HALF OF PENN.

LITTLE REASON...OR FOR THAT MATTER OPERATIONAL NAM/SREF
SUPPORT...TO SUGGEST A COMPLETE CHANGE TO PLAIN RAIN ACROSS THE
CENTRAL AND NRN TIER ZONES UNTIL THIS EVENING AS SFC DEWPOINTS IN
THE UPR TEENS EAST...TO MID 20S ACROSS THE WEST...ARE PREVENTING A
RAPID TEMP RISE VIA LLVL EVAP COOLING.

QPF (WHICH WILL BE MOST WIDESPREAD OVER THE SOUTH) WILL BE LIGHT
DURING THESE NEAR TO SUB FREEZING TEMPS LATE TODAY...SO NO SIGNIF
ICE ACCUM WILL OCCUR.

MAX TEMPS WILL BE REACHED RIGHT AT 00Z MONDAY AS THE LLVL FLOW
SLOWLY VEERS AND TEMPS/DEWPOINTS CREEP UPWARD.

&&

.SHORT TERM /7 PM THIS EVENING THROUGH 6 AM MONDAY/...
OUR CURRENT...PROLONGED WINTER WEATHER ADVISORY  WILL HANG ON
INTO THIS EVENING ACROSS PARTS OF THE CENTRAL AND NORTHERN MTNS OF
PA...WITH THE MTNS NORTH AND NE OF KIPT MOST AT RISK FOR AN
EXTENDED PERIOD OF LIGHT ICING.

ELEVATED CONVECTION STILL LOOKS TO BE A POSSIBILITY WITH +10C
THERMAL RIDGE AT 850 MB AND HIGHER PWATS TRACKING ACROSS SOUTH
CENTRAL PA TONIGHT...SO WL HOLD ONTO THE CHC OF A TSRA THAT WAS
PREVIOUSLY ADDED TO THE GRIDS. MODEL DATA CONTS TO INDICATE
MARGINAL INSTABILITY ABV 900MB AND SIG LARGE SCALE LIFT IN ADVANCE
OF APPROACHING COLD FRONT.

THE MAIN UPPER SHORT WAVE AND STRONGEST UVVEL BENEATH THE 130 KT
300 HPA JET WILL CARRY HIGHER PWATS (OVER ONE INCH) AND LIKELY
OVER ONE HALF INCH OF RAINFALL NE FROM THE OHIO RIVER VALLEY
BETWEEN ABOUT THIS EVENING THROUGH 06Z MONDAY

COLD FRONT WILL SWEEP THRU THE AREA DURING THE PREDAWN HOURS MON
MORNING...FOLLOWED BY STRONG COLD ADVECTION AND WIND GUSTS LIKELY
EASILY EXCEEDING 35 MPH. THROUGH COLLAB WITH PHI AND LWX...WILL BE
CONSIDERING UPGRADING THE WIND ADVIS (CURRENTLY IN AFFECT CWA-WIDE
MONDAY) TO A HIGH WIND WARNING FOR MONDAY ACROSS THE LAUREL
HIGHLANDS AS HIGHLY ANOMALOUS...60 KT WIND CONTOUR VIA THE NAM IS
LOCATED JUST BELOW 2 KFT AGL MONDAY AFTERNOON. ALSO...AFTER THE
CURRENT WSW (ADVISORY) FOR THE WINTRY MIX EXPIRES THIS
EVENING...WE MAY TRANSITION TO A SNOW ADVIS FOR THE LAURELS
MONDAY...AND UPGRADE THE LES WATCH TO A WARREN FOR AT LEAST WARREN COUNTY.

WSW BLYR FLOW SHOULD CONFINE SIG LAKE EFFECT SNOW SHOWERS MONDAY
MORNING TO SNOW BELT OF NW PA...WHERE SEVERAL INCHES SEEM
PROBABLE BY LATE IN THE DAY MONDAY. LAKE EFFECT SNOW WATCH BEGINS
12Z MONDAY AND WILL CONTINUE THROUGH TUESDAY AFTERNOON.

&&

.LONG TERM /MONDAY THROUGH SUNDAY/...
SIGNIFICANT LAKE EFFECT SNOWFALL CONDS ACROSS THE NORTHWEST
MOUNTAINS AND LAUREL HIGHLANDS MONDAY NIGHT INTO TUESDAY ON THE
BACKSIDE OF 500MB HEIGHT FALL CENTER/DEEPENING SFC LOW OVER THE
CANADIAN MARITIMES. LAKE EFFECT SNOW WATCH IN EFFECT FROM MONDAY
THROUGH TUESDAY AFTERNOON.

TEMPS WILL REMAIN BELOW NORMAL FOR THE PERIOD WITH 850 MB TEMP
ANOMALIES -1 TO -3 S.D. BELOW NORMAL. PERIODS OF SNOW SHOWERS AND
FLURRIES WILL BE COMMON...PARTICULARLY ON WEDNESDAY AS A CLIPPER
LOW DIVES SOUTHEASTWARD THROUGH THE MID MS/OH VLY AND ALONG/SOUTH
OF THE MASON DIXON BRINGING A BAND OF SNOW TO THE AREA WED-THUR.

LE SHSN SHOULD BEGIN TO WANE BY EARLY WED AS FLOW WEAKENS AND BACKS
IN RESPONSE TO AN APPROACHING CLIPPER LOW DIVING SEWD THRU NRN
PLAINS AND INTO THE OH VLY/WV PNHNDL. MDLS GRADUALLY CONVERGING ON
AFOREMENTIONED SFC LOW TRACK...WITH CONDS COLD ENUF FOR A BAND OF
SNOW ALONG/NORTH OF THE EVENTUAL TRACK. AT FIRST GLANCE...EVOLUTION
OF THIS SYS LOOKS SOMEWHAT LIKE THE 18 NOV EVENT...BUT STILL WAY TOO
FAR OUT TO GET SPECIFIC.

SFC HI PRES IS FCST TO BUILD INTO THE AREA IN THE WAKE OF THE
CLIPPER WITH LE SNOW SHOWERS DEVELOPING ACROSS THE WESTERN HIGH
TERRAIN INTO THE EARLY PART OF THE WKEND. AS THE SFC HI MOVES OFF
THE MID-ATLANTIC COAST...FLOW PATTERN APPEARS TO TRANSITION FROM A
MEAN ERN TROF TO MORE OF A PROGRESSIVE/ZONAL FLOW BY EARLY IN THE
WEEKEND. THIS SHOULD TRANSLATE INTO A MODERATION IN TEMPS BACK
TOWARD MORE SEASONABLE READINGS.

&&

.AVIATION /21Z SUNDAY THROUGH FRIDAY/...
ROUND TWO OF PCPN (RAIN AND FZRA) CONTINUES TO SLIDE EAST ACROSS
THE SOUTHERN THIRD OF PENN THIS AFTERNOON...WITH MORE WIDESPREAD
RAIN WITH POCKETS OF FZRA EXPECTED TO MOVE NE FROM THE OHIO VALLEY
CONTINUING THE CURRENT WIDESPREAD MVFR AND IFR CONDITIONS THROUGH
MUCH OF TONIGHT.

THE STABLE...NEAR SFC LAYER WITH A LIGHT SOUTH TO SE FLOW TOPPED
BY INCREASING SOUTHWEST FLOW ABOVE 1.5KFT AGL WILL SUPPORT LLWS
PRIOR TO A STRONG COLD FRONTAL PASSAGE LATE TONIGHT.

ELEVATED INSTABILITY MAY EVEN TRIGGER A FEW RUMBLES OF THUNDER NEAR
THE TIME OF THE CFROPA.

VERY WINDY AND COLDER CONDITIONS WILL OCCUR MONDAY INTO
TUESDAY...RESULTING IN AREAS OF SIGNIFICANT LAKE EFFECT/OROGRAPHIC
SNOWS ACROSS THE NW MTNS AND LAUREL HIGHLANDS. WIDESPREAD IFR
CONDITIONS ARE EXPECTED ACROSS THE WRN AND NRN MTNS IN SNOW
SHOWERS WITH AREAS OF MVFR ACROSS THE CENTRAL RIDGE/VALLEY REGION
(TAF SITES KAOO...KUNV AND KIPT).

WINDS WILL SHIFT TO WESTERLY AND QUICKLY INCREASE TO SUSTAINED
VALUES BETWEEN 20-30 JUST AFTER THE CFROPA AND CONTINUE INTO
MONDAY NIGHT. WIND GUSTS IN THE 35-45KT RANGE WILL OCCUR DURING
THIS SAME PERIOD. FLURRIES AND SCATTERED SNOW SHOWERS WILL FLY ACROSS
THE CENTRAL AND SE.

ANOTHER...ALBEIT SOMEWHAT WEAKER STORM SYSTEM MOVING SOUTHEAST
FROM CANADA DURING THE MIDWEEK WILL BRING PERIODS OF MVFR TO IFR
CIGS AND VSBYS IN SNOW/SNOW SHOWERS LATE TUESDAY NIGHT INTO
THURSDAY.

MAINLY VFR FLYING CONDITIONS ARE EXPECTED TO RETURN FRIDAY AS HIGH
PRESSURE BUILDS IN FROM THE MIDWEST.
