AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE STATE COLLEGE PA
342 PM EDT THU JUL 19 2012

.SYNOPSIS...
A STATIONARY FRONT WILL REMAIN DRAPED ACROSS CENTRAL PENNSYLVANIA
TODAY. A SLOW MOVING WAVE OF LOW PRESSURE WILL RIDE ALONG THIS
BOUNDARY...PASSING JUST SOUTH OF PENNSYLVANIA FRIDAY AND SATURDAY.
A WEAK RIDGE OF HIGH PRESSURE WILL BUILD SOUTH ACROSS THE AREA
SUNDAY AND MONDAY. TEMPERATURES FOR MUCH OF NEXT WEEK WILL BE
NEAR...TO SLIGHTLY ABOVE NORMAL.

&&

.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...
LFC HIT IN SPOTS IN THE FAR SE...BUT HIGHER POPS ON ORDER FOR THE
WEST AND CENTRAL COS EARLY THIS EVENING AS A LINE OF MULTIPLE BOW
ECHOES MOVES IN FROM THE WEST. INSTABILITY HAS CREEPED UP AS
CLOUDS HAVE THINNED OVER MOST OF THE AREA. EXPECT ONLY A SLIGHT
WEAKENING TO THE SHOWERS/STORMS AS THEY MOVE EASTWARD. VORT
MAX/MCV WILL VERY SLOWLY MOVE W-E ALONG THE NY BORDER TONIGHT.
THIS FEATURE WILL LOWER THE HEIGHTS ALOFT AND LEAD TO ELEVATED
INSTABILITY. RAINFALL WILL BE ENHANCED DUE TO THE SERLY/UPSLOPING
FLOW INTO THE NORTHEASTERN HALF OF THE AREA TONIGHT. THE SHORT
WAVE TROUGH WILL THEN STALL OUT OVER NERN PA/CENTRAL NY STATE. QPF
IS OF CONCERN THIS PKG WITH UP TO 2 INCHES OF RAIN PROGGED BY MANY
MDLS AND AGREED UPON BY THE SREF ENSEMBLE MEAN. HOWEVER...THE MDLS
ALSO SHOW SIGNS OF CONVECTIVE FEEDBACK. WILL HOLD OFF ON ANY FLOOD
WATCH AT THIS TIME DUE TO THE HIGH FFG/S AND LOW PROBABILITY OF
REACHING FLOOD STAGE AT ANY RIVER POINTS. FFG/S RUN IN THE 4-5
INCH RANGE FOR ANYTHING LONGER THAN 3 HRS. EVEN 1 HR NUMBERS ARE
IN THE 3 INCH RANGE IN THE AREA WHERE THE HEAVIEST RAIN IS
EXPECTED. THE LOW STREAM LEVELS WILL HELP KEEP THE STREAMS IN
CHECK IN THIS EVENT. HOWEVER...THE RAIN PROGGED IS USUALLY HEAVY
ENOUGH TO CAUSE SMALL STREAM AND URBAN DRAINAGE PROBLEMS.

HIGH MOISTURE AND CLOUDS WILL KEEP THE TEMPS MILD THROUGH THE
NIGHT. WILL KEEP VERY CLOSE TO MOS GUIDANCE...OR A BIT HIGHER.
THE LIGHT WIND WILL ALSO CREATE POCKETS OF FOG...MAINLY IN THE
LOW-LYING AREAS. WILL JUST MENTION PATCHY FOG AT THIS POINT.

&&

.SHORT TERM /6 AM FRIDAY MORNING THROUGH 6 PM FRIDAY/...
CATEGORICAL POPS WILL CONTINUE FOR ALMOST THE ENTIRE DAY AS THE
WEAK UPPER TROUGH/LOW STICKS TIGHT FOR MOST OF THE DAY. IT DOES
APPEAR THAT THE WESTERLIES FINALLY PICK UP ENOUGH LATER IN THE DAY
TO MOVE THE FOCUS FOR THE HEAVY RAIN OFF TO THE EAST. THE QPF IS
AGAIN THE BIGGEST PROBLEM OF THE FORECAST FOR THIS PERIOD. THE
STORM TOTAL OF 3-3.5 INCHES IN THE GRIDS IS EXPECTED TO BE ENOUGH
TO RAISE STREAM LEVELS SIGNIFICANTLY...BUT WITH THE VERY LOW FLOWS
PRESENT AT THE BEGINNING OF THE EVENT AND THE LONG DURATION...FEW/NO
PROBLEMS ARE EXPECTED TO OCCUR ON THE LARGER STREAMS AND RIVERS.
THE MOST LIKELY SCENARIO IS THAT MINOR PROBLEMS ALONG THE SMALLER
CREEKS WILL OCCUR. MAXES ARE GOING TO BE VERY COOL FOR THIS TIME
OF YEAR WITH LESS THAN A 5 DEG DIURNAL RISE FOR MANY AREAS. THE NE
MAY NOT RISE AT ALL AND THE SW COULD SEE 10F RISE IN TEMPS THROUGH
THE DAY.

&&

.LONG TERM /FRIDAY NIGHT THROUGH THURSDAY/...
STEADY...MODERATE TO HEAVY /AND MAINLY STRATIFORM RAIN/ WILL BE
ONGOING ACROSS MUCH OF CENTRAL AND EASTERN PENN TO BEGIN THIS
PERIOD.

THE SLOW MOVING UPPER SHORT WAVE...STALLED OUT FRONTAL BOUNDARY
ACROSS THE MID ATLANTIC REGION...AND ANOMALOUS/DEEP SERLY UPSLOPE
FLOW OF ATLANTIC MOISTURE WILL BEGIN TO SHIFT EAST OF THE REGION BY
THE MID MORNING HOURS SATURDAY.

STORM TOTAL RAINFALL FROM LATE THURSDAY THROUGH SAT MORNING WILL BE
A SOLID 1-3 INCHES WITH LOCALIZED 4 INCH AMOUNTS POSSIBLE WHERE
HEAVIER CONVECTIVE ELEMENTS FORM/LIFT NORTH OF THE FRONTAL BOUNDARY.

THE BASE OF THE STRATUS WILL LOWER TO AROUND 1500 FT MSL FRIDAY
NIGHT...THEN JUST LIFT A FEW HUNDRED FEET SAT MORNING...BEFORE
DISSIPATING DURING SAT AFTERNOON. PAINTED THIS /AND ADDITIONAL
ELEMENTS/ IN OUR WEATHER GRIDS AS PERIODS OF RAIN/DRIZZLE AND AREAS
OF FOG.

EXTENSIVE LOW...STRATUS CLOUDS COULD LINGER THROUGH MOST OR ALL OF
SATURDAY UNDER A WEAK/MOIST NERLY FLOW. PERIODS OF DRIZZLE ARE
POSSIBLE...MAINLY ACROSS THE CENTRAL MTNS AND WRN POCONOS.

SATURDAY WILL BE QUITE COOL /PERHAPS UP A 30F DIFFERENCE IN SOME
PORTIONS OF CENTRAL PENN COMPARED TO THE SWELTERING HIGHS IN THE 90S
EXPERIENCED TUESDAY AND WEDNESDAY/. MAX TEMPS SATURDAY WILL RANGE
FROM THE U60S TO LOWER 70S IN THE CENTRAL AND WEST...TO THE MID 70S
IN THE SE.

POSITIVE TILT...SFC AND UPPER LEVEL RIDGE WILL NOSE INTO THE REGION
FROM THE WEST SATURDAY NIGHT AND SUNDAY BRINGING PARTIAL
CLEARING...LIGHT WINDS...AND DRY WEATHER.

HIGH TEMPS SUNDAY WILL REBOUND BACK TO NEAR OR JUST SLIGHTLY BELOW
NORMAL. WILL STAY WITH CONTINUITY AND INCLUDE JUST A FEW ISOLATED
SHRA/TSRA AFTER 18Z SUNDAY. HOWEVER...COVERAGE SHOULD BE QUITE
SPARSE AS MID LEVEL LAPSE RATES WILL BE AOB 6C/KM.

THE SERN CANADA AND NE U.S. UPPER TROUGH AMPLIFIES THROUGH THE
MIDWEEK PERIOD. SEVERAL FAST MOVING...ALBEIT RATHER FLAT SHORTWAVES
WILL RACE SOUTHEAST /WITH SOME OBVIOUS TIMING UNCERTAINTY/ AND
TRIGGER SOME MAINLY AFTERNOON/EARLY EVENING SCTD SHOWERS AND TSRA
MONDAY AND TUESDAY.

HEIGHTS BEGIN TO RISE WEDNESDAY ACCOMPANIED BY AN AREA OF HIGH
PRESSURE AT THE SFC DRIFTING OVERHEAD. KEPT IT DRY WITH POPS ONLY
AROUND 10 PERCENT WEDNESDAY. WARMER AIR WILL PUSH EAST INTO THE
REGION AT THE SFC AND ALOFT LATER IN THE WEEK BRINGING A CHANCE FOR
A FEW SHOWERS AND ISOLATED TO SCATTERED TSRA.

TEMPS FOR MUCH OF NEXT WEEK SHOULD BE NEAR TO SLIGHTLY ABOVE NORMAL
WITH MODERATE DEWPOINTS GENERALLY IN THE U50S NORTH...TO MID 60S IN
THE SOUTH.

&&

.AVIATION /19Z THURSDAY THROUGH TUESDAY/...
SFC FRONTAL BOUNDARY VERY DIFFICULT TO PLACE IN SFC ANALYSIS AT
THIS TIME. IT IS OVERHEAD SOMEWHERE NORTH OF KUNV AND KSEG. IT
SHOULD MOVE VERY LITTLE THROUGH THE TAF VALID PERIOD. AN MCS
MOVING IN FROM OH SHOULD BRING WIDESPREAD SHRA AND TSRA INTO KJST-
KAOO-KUNV IN THE NEXT TWO HOURS. THE UPPER LEVEL ENERGY ASSOCIATED
WITH THE OLD MCS WILL SLIDE W-E ALONG THE NY BORDER TONIGHT. SFC
WINDS WILL BE LIGHT BUT MAINLY EASTERLY IN THE EAST AND
NORTH...BUT LIGHT AND SOUTH OVER KJST. THE UPSLOPE FLOW WILL LEAD
TO AREAS OF FOG/LOW CIGS TONIGHT WHICH WILL THEN BE TOUGH TO BREAK
ON THURSDAY. EXPECT POOR FLYING CONDITIONS THROUGH THE DAY.
CONVECTIVE POTENTIAL IS LOWER ON THURS DUE TO EXPECTED LACK OF
CLEARING. UNSETTLED CONDITIONS WILL PERSIST INTO SAT AS ADDITIONAL
WAVES OF LOW PRESSURE MOVE ALONG THE FRONT.

OUTLOOK...
FRI-SAT...MVFR BECOMING IFR WITH PERIODS OF RAIN AND SCT TSTMS
CENTRAL/SOUTH.
SUN...MVFR/IFR IN THE MORNING...THEN IMPROVING CONDITIONS.
MON-TUE...MAINLY VFR...SCT PM TSTMS POSSIBLE.

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