AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE STATE COLLEGE PA
736 PM EST SAT DEC 22 2007

.SYNOPSIS...
A STRONG SURFACE HIGH PRESSURE OFF THE NEW ENGLAND COAST WILL KEEP
A LOT OF LOW CLDS AND A FEW SHOWERS AROUND TONIGHT...ALONG WITH
SOME AREAS OF DRIZZLE. A STRONG STORM SYSTEM MOVING ACROSS THE
GREAT LAKES ON SUNDAY WILL BRING A MILD DAY TO THE AREA ON SUNDAY
WITH SHOWERS AND EVEN A CHANCE OF A THUNDERSTORM. A STRONG UPPER-
LEVEL SHORT WAVE WILL MOVE THROUGH THE REGION LATE SUNDAY AND
EARLY MONDAY...BRINGING ANOTHER SHOT OF COLDER AIR AND GUSTY WINDS
TO THE AREA. AN AREA OF HIGH PRESSURE SHOULD TAKE CONTROL OF THE
WEATHER AGAIN ON TUE AND FOR MOST OF THE COMING WEEK. ANOTHER
STORM TRACKING ACROSS THE LAKES LATE IN THE WEEK WILL BRING A CHC
OF RAIN TO THE AREA FOR NEXT SATURDAY.

&&

.NEAR TERM /UNTIL 11 PM THIS EVENING/...
A STRONG SURFACE ANTICYCLONE TO OUR NORTHEAST IS KEEPING LOW-
LEVEL COLD AIR ENTRENCHED OVER THE REGION. WARMER SOUTHEAST WINDS
RUNNING OVER THIS COLD AIR IS MAINTAINING THE LOW CLOUDS. LIGHT
DRIZZLE IS POSSIBLE ALL EVENING...BUT MOST PLACES WILL NOT HAVE
ANY. SOME THINNER SPOTS IN THE LOW CLOUDS ARE ALONG THE BORDER AND
IN NRN MD...AND COULD WORK INTO THE FAR SRN COUNTIES. TEMPS WILL
HOLD OR RISE SLIGHTLY FOR THE EVENING.

&&

.SHORT TERM /11 PM THIS EVENING THROUGH 6 PM SUNDAY/...
WARMER AIR TRIES TO WORK DOWN FROM ABOVE TONIGHT...AND SHOULD KEEP
TEMPS STATIC AND GRADUALLY PUSH THEM HIGHER. TEMPERATURES SHOULD
PEAK LATE SUN MORNING OR EARLY AFTERNOON IN THE WEST AND MID-
AFTERNOON IN THE EAST AS A STRONG FRONT MOVES THROUGH THE REGION.
FROPA SHOULD BE AROUND 18Z IN THE WEST AND 22-23Z IN THE EAST.
EXPANDED THE COVERAGE OF CHC OF THUNDER MENTIONS IN THE GRIDS TO
INCLUDE MOST OF THE REGION...WITH ELEVATED INSTABILITY PRESENT
OVER MUCH OF THE REGION FOR A SHORT TIME.

THE FRONT ALSO HAS THE SHARP N-S LOOK OFTEN ASSOCIATED WITH NARROW
COLD FRONTAL RAIN BANDS. THIS SUGGESTS MOST OF THE RAIN WILL BE A
FEW HOURS EITHER SIDE OF THE COLD FRONT. IT IS ALSO A WORRY FOR
SEVERE WIND GUSTS RIGHT ALONG THE FRONT IF WE CAN MANAGE ANY SORT
OF SFC INSTABILITY. MOST LIKELY THE COLD AIR DAMMING WILL KEEP
HOLDING ON AND THE INVERSION WILL KEEP GUSTS FROM MAKING IT DOWN
TO THE SFC.

MOST OF THE SIGNIFICANT RAIN SHOULD OCCUR DURING THE DAYLIGHT
HRS...WITH SREF MEMBERS SHOWING AROUND 1 INCH OF QPF. THIS MAY
COMBINE WITH 1-2 INCHES OF WATER EQUIV ON THE GROUND IN SLEET/SNOW
PACK TO MAKE SOME SMALLER STREAMS RISE TO NEAR BANKFULL ON SUNDAY
EVENING. THE LARGER RIVERS AND STREAMS CAN HANDLE THAT RUNOFF
EASILY WITHOUT FLOODING.

RAIN COULD END RAPIDLY AS THE COLD FRONT PASSES...AND MAY TURN TO
SNOW SHOWERS IN THE NORTHWEST AND WESTERN MOUNTAINS BY NIGHTFALL.

GRADIENT WINDS ARE OUR OTHER MAJOR CONCERN. BUT...MIXING DOWN HIGH
WIND GUSTS AHEAD OF THE COLD FRONT IS NOT A USUAL THING IN
CENTRAL PA. SOME OF THE RIDGE TOPS MAY GET GUSTY BEFORE THE FRONT
BUT MOST OF THE GUSTY WINDS WILL WAIT UNTIL BEHIND THE FRONT LATE
SUN...AND SUN NIGHT...AS WINDS IN THE LOW LEVELS ALIGN BETTER. FOR
NOW...WILL HOLD GUSTS TO LESS THAN 40 KTS...BUT WE COULD EASILY
SEE ADVISORY GUSTS FOR THE NORTHERN AND WESTERN MTS LATE SUNDAY.

&&

.LONG TERM /SUNDAY NIGHT THROUGH SATURDAY/...
AN INTERESTING SYSTEM FOR SUNDAY. RIGHT NOW...IT LOOKS LIKE THE
MOISTURE WILL NOT QUITE PHASE WITH THE DYNAMICS...THUS WHILE A
RUMBLE OF THUNDER WILL BE POSSIBLE...IT WILL BE BORDERLINE FOR
SEVERE STORMS. RIGHT NOW...HAVE GUSTY WINDS IN FCST FOR LATE
SUNDAY AFT...INTO THE FIRST PART OF MONDAY. MAY NEED A WIND
ADVISORY AT SOME POINT...BUT IT STILL MAINLY A THIRD PERIOD EVENT.

A DRY SLOT WILL BRING A QUICK END TO THE RAIN SUNDAY EVENING. MUCH
OF THE AREA WILL BE DRY OVERNIGHT...EXCEPT FOR THE FAR N...WHERE
BANDS OF LAKE EFFECT WILL SET UP LATE ON A STRONG WEST FLOW.

WINDS WILL SLOWLY SHIFT MORE TO THE NW LATE MONDAY...THUS KEPT
A CHC OF SNOW SHOWERS IN FOR MONDAY NIGHT...BUT THIS WILL BE
LIMITED...AS THE BEST DYNAMICS ARE LIFTING OUT BY THEN.

ON CHRISTMAS DAY AN AREA OF HIGH PRESSURE MOVES INTO THE REGION
FROM THE SOUTHWEST. THIS SHOULD REDUCE THE SNOW SHOWER ACTIVITY IN
NW PA AND CLEAR OUT THE SKIES IN THE SOUTH.

THIS ARE OF HIGH PRESSURE SHOULD REMAIN OVER THE REGION WEDNESDAY
PRODUCING A MAILY DRY AND PARTLY SUNNY DAY. A WEAK FRONT MOVES
OVER THE REGION ON THURSDAY. MOST MREF MEMBERS SHOW LITTLE OR NO
PRECIPITATION WITH THIS SYSTEM. FOR NOW...LEFT POPS CLOSE TO WHAT
WAS THERE.

DID CUT OUT PCPN FOR THU NIGHT AND FRIDAY...AS THIS WEAK SYSTEM
MOVES OUT...AND WE ARE AHEAD OF THE NEXT SYSTEM. ALSO MREFS ARE
DRY FOR THIS PERIOD.

HPC AND MREFS SHOW ANOTHER SYSTEM NEXT WEEKEND SIMILAR TO THIS
WEEKEND...SO WENT WITH CHC OF RAIN ON SAT.

&&

.AVIATION /01Z SUNDAY THROUGH THURSDAY/...
REALTIVELY WARMER SOUTHERLY WINDS WILL INCREASE AS A FRONT
APPROACHES THE AREA. NEAR THE SURFACE...SOUTHEAST WINDS WILL KEEP
COOLER AIR TRAPPED SO LLWS WILL BE COMMON. WINDS FROM 170-180
DEGREES UP TO 40KTS ARE POSSIBLE FROM FL020 AND UP OVERNIGHT.
THESE WINDS WILL MIX DOWN DURING THE DAY SUNDAY AS THE FRONT
APPROACHES MAKING FOR QUITE A TURBULENT DAY.

IFR CLOUDS WILL CONTINUE OVERNIGHT AS LOW LEVEL MOIST AIR IS
TRAPPED UNDER THE BRISK WINDS ALOFT. ALSO...AS MILDER AIR DOES
MAKE ITS WAY TO THE SURFACE...IT WILL OVERRUN LINGERING SLEET AND
SNOW COVER. FOG IS POSSIBLE OVER THE HIGHER ELEVATION FIELDS.

MOST OF THE RAIN ON SUNDAY SHOULD BE CONFINED TO THE FEW HOURS
CLOSEST TO THE COLD FRONTAL PASSAGE...WHICH SHOULD BE AROUND
18-19Z IN THE WEST AND 22-23Z IN THE FAR EASTERN COS.

BEHIND THE FRONT LATER SUN INTO SUN NIGHT...THE SFC WINDS WILL
TURN WESTERLY...INCREASE AND BECOME QUITE GUSTY. THE WESTERLY
UPSLOPE FLOW WILL KEEP LOWER CIGS AND PERHAPS SOME -SHSN IN THE
HIGHER TERRAIN SITES OF KBFD/KJST BUT REMAINDER OF CWA WILL
TRANSITION BACK TO VFR FOR MONDAY AND TUESDAY.

&&

.CTP WATCHES/WARNINGS/ADVISORIES...
NONE.
