Flash Flooding in Pennsylvania, March 20, 2008

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
842 PM EDT WED MAR 19 2008

.SYNOPSIS...
STRENGTHENING LOW PRESSURE OVER PENNSYLVANIA THIS EVENING WILL TRACK
ACROSS NEW YORK OVERNIGHT AND INTO NEW ENGLAND TOMORROW. HIGH
PRESSURE WILL MOVE IN BEHIND THE LOW FOR THE END OF THE WEEK.
ANOTHER FAST MOVING LOW WILL CROSS THE REGION FRIDAY NIGHT AND
SATURDAY. ANOTHER LOW MAY AFFECT THE AREA LATE SUNDAY AND MONDAY.

&&

.NEAR TERM /THROUGH TONIGHT/...
THE RADAR REMAINS ALIVE THIS EVENING WITH THE FIRST BATCH OF RAIN
DISSIPATING AS IT MOVES OFF THE COAST AND THE SECOND BATCH TRACKING
ACROSS CENTRAL PENNSYLVANIA. THE FLOOD WATCH REMAINS POSTED FOR THE
NORTHWESTERN COUNTIES WITH FLASH FLOOD GUIDANCE QUITE LOW FOR THE
OVERNIGHT HOURS. TOTAL QPF NOW APPEARS TO BE IN THE .50 TO 1.25 INCH
RANGE FROM SOUTH TO NORTH ACROSS THE CWA WITH HIGHER VALUES IN ANY
STRONG CONVECTION THAT DEVELOPS. THE CHC OF THUNDER HAS BEEN
RETAINED IN THE FORECAST WITH THE PRESENCE OF A COUPLE HUNDRED J/KG
OF CAPE, SFC BASED AND/OR ALOFT (THE GFS IS MORE CONDUCIVE TO SB
CONVECTION RATHER THAN ELEVATED). SPS HAS KEPT OUR SOUTHERN AREAS
(DELMARVA AND EXTREME SOUTH NJ) IN A SLIGHT RISK FOR SVR OVERNIGHT.
IF ANY SVR DEVELOPS, THE THREAT WILL LIKELY COME FROM DAMAGING
WINDS. LOOKING UPSTREAM, IT APPEARS LIGHTNING IS HAVING A TOUGH TIME
MAKING NORTH OF THE MASON-DIXON LINE.

&&

.SHORT TERM /THURSDAY THROUGH FRIDAY/...
FAIR CONDITIONS WILL RETURN IN THE SHORT TERM WITH HIGH PRESSURE
ACROSS THE OHIO VALLEY AND THE STORM (FROM THE NEAR TERM) HAVING
MOVED OFF THE NEW ENGLAND COAST. THE WINDS WILL BE BRISK AND MUCH
DRIER AIR WILL MOVE IN. A SMALL CHC OF A SNOW SHOWER WILL BE KEPT
IN ACROSS THE SOUTHERN POCONOS UNDER THE STILL CYCLONIC FLOW.
WHILE WINDS LOOK FAIRLY STRONG, IT APPEARS THAT THEN NUMBERS WILL
COME UP A BIT SHORT OF A WIND ADVISORY, SO IN CONCERT WITH
SURROUNDING OFFICES, THE NPW FLAG IS BEING HELD AT THIS POINT. GUSTS
COULD STILL REACH 40 MPH THURSDAY HOWEVER. FAIR WEATHER WITH LESS
GUSTY WINDS EXPECTED FRI AS THE RIDGE IS EXPECTED TO EXTEND OVER THE
AREA BY THE AFTERNOON. HIGH TEMPERATURES THU AND FRI CLOSE TO NORMAL
WITH LOW TO MID 50S MOST AREAS AND SOME 40S UP NORTH.

&&

.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
THE UPPER FLOW WILL BE PROGRESSIVE DURING THE EXTENDED PERIOD
OFFERING THE POSSIBILITY OF QUICK CHANGES AND PROBABLY LOWER THAN
AVERAGE PREDICTABILITY OF THE FEATURES.

THE FIRST SYSTEM THAT WILL AFFECT OUR AREA IN THE EXTENDED PERIOD
WILL BE A CLIPPER TYPE SYSTEM THAT WILL CRUISE BY JUST TO THE
SOUTH OF OUR FORECAST AREA FRIDAY NIGHT AND SATURDAY. THE TRACK OF
THE SYSTEM AND THE FACT THAT IT WILL BE ON THE HEELS OF THE
CURRENT STORM MEANS THAT MOISTURE AND THUS QPF WILL NOT BE VERY
HIGH WITH THE STORM, BUT A TENTH TO A QUARTER OF AN INCH IS
POSSIBLE. TEMPERATURES TRENDS WOULD HAVE MAINLY RAIN WITH THE
FEATURE AND SOME SNOW IN THE MIX NORTH AND WEST OF PHILADELPHIA
DURING FRI NIGHT. CHC POPS ARE IN THE FORECAST AT THIS POINT.

THE SECOND SYSTEM THAT WILL AFFECT OF AREA WILL BE A LOW PRESSURE
SYSTEM THAT WILL DEVELOP OVER THE GULF OF MEXICO ON SUNDAY AND THEN
MOVE UP THE EAST COAST MONDAY AND THEN TO NEW ENGLAND TUESDAY. THE
TRACK OF THE LOW COULD BRING ANOTHER ROUND OF RAINS (HEAVY?) AND
INLAND SNOWS (HEAVY?) TO THE EAST COAST. THE 00Z ECMWF SHOWED A
SOLUTION WHICH PLACED THE LOW JUST FAR ENOUGH OFF THE COAST AND
DEEP ENOUGH TO GIVE BIG SNOWS TO THE METRO AREAS. FORTUNATELY THE
OTHER MODELS ARE NOT AS AGGRESSIVE AT THIS POINT AND THE 06Z AND
12Z GFS HAVE PUSHED THE LOW OUT TO SEA. THERE WILL BE PLENTY TO
WATCH WITH THIS LOW OVER THE NEXT FEW DAYS SO STAY TUNED.

&&

.AVIATION /00Z THURSDAY THROUGH MONDAY/...
THE AREA OF RAIN, LIGHT TO MODERATE, THAT HAS BEEN OVER THE TAF
SITES SINCE EARLY WEDNESDAY AFTERNOON WAS DIMINISHING AND BECOMING
MORE SCATTERED AT 00Z AS THE EFFECTS OF THE SURFACE WARM FRONT WANE.
VISIBILITIES AND CEILINGS MAY IMPROVE A BIT, IN SCATTERED AREAS AND
TEMPORARILY, TO MARGINAL VFR TO VFR WITH LOCAL IFR CONDITIONS IN
PRECIPITATION, UNTIL THE COLD FRONT NEARS IN THE 03Z TO 05Z TIME
FRAME WHEN MORE SHOWERS AND SOME THUNDERSTORMS WILL APPROACH. WITH
LOW LEVEL WINDS INCREASING OUT OF THE SOUTH-SOUTHWEST TO ABOUT 50
KNOTS, A WIND SHEAR REMARK WAS ADDED FOR EARLY TONIGHT AHEAD OF THE
FRONT FOR ALL TAF SITES.

MODEL GUIDANCE AND SOUNDINGS WERE INDICATING FAIRLY SUBSTANTIAL
DESTABILIZATION IN THE LOWER TO MID DELAWARE VALLEY BY 06Z, WITH
LIFTED INDICES DROPPING TO AROUND MINUS 1 OR MINUS 2, AND ALSO
INDICATING MODEST CAPE (OF THE MOST UNSTABLE VARIETY). SO, A TEMPO
GROUP EXPLICITLY MENTIONING THUNDERSTORMS WILL BE ADDED TO THE TAFS
IN THE 04Z TO 06Z TIME FRAME (AN HOUR EARLIER WEST AND LATER
SOUTHEAST), WITH COLD FRONTAL PASSAGE WELL-AGREED UPON BY THE GFS
AND THE ECMWF AT 06Z FOR THE CENTRAL TAF SITES. THE FRONT SHOULD BE
FAIRLY FAST-MOVING, WITH IMPROVEMENT OCCURRING IN THE POST-FRONTAL
ENVIRONMENT TO MARGINAL VFR AND EVEN VFR, WITH VFR CEILINGS BY 12Z
AND A FRESHENING WEST WIND. WINDS ARE PROGGED TO VEER SLIGHTLY TO
WEST-NORTHWEST AND INCREASE IN SPEED BY MIDDAY, WHEN GUSTS WERE
INCREASED TO 34 KNOTS FOR MIDDAY AND AFTERNOON. STRATOCUMULUS
CEILINGS SHOULD SCATTER OUT BY LATE MORNING OR MIDDAY.

BEYOND THE TAF VALID PERIOD OF 00Z FRIDAY, THE OFFSHORE FLOW WILL
CONTINUE INTO THURSDAY NIGHT, THEN GRADUALLY DIMINISH AS HIGH
PRESSURE BUILDS IN FROM THE WEST. LOW PRESSURE WILL MOVE IN FROM THE
OHIO VALLEY AND STRAIGHT TO THE COAST DURING THE DAY SATURDAY WITH
POSSIBLY SOME MIXED PRECIPITATION FOR THE NORTHERN TWO TAF SITES FOR
SATURDAY, AND JUST RAIN SOUTH.

&&

.MARINE...
SEAS AND WINDS WILL BE INCREASING THIS EVENING AND GALE CONDITIONS
EXPECTED OVERNIGHT. A SOUTHERLY WIND WILL TURN TO THE WEST AND
NORTHWEST AND UP TO GALE FORCES AS LOW PRESSURE MOVES TO THE NORTH
OF THE COASTAL WATERS AND THE FRONT CLEARS THE COAST BEFORE SUNUP ON
THURSDAY.

A STRONG WEST TO NORTHWEST FLOW WILL BLOW FOR THURSDAY AND CONTINUE
INTO THURSDAY NIGHT BEFORE DIMINISHING. HIGH PRESSURE OVER THE OHIO
VALLEY OVER THE WEEKEND WILL REACH THE COAST FOR FRIDAY NIGHT AND
SATURDAY. ANOTHER WEAK LOW, WITH WEAK PRESSURE GRADIENT, WILL MOVE
TO THE COAST SATURDAY.

THE WEATHER OFFSHORE TO THE CANYONS WILL BE EQUALLY AS ROUGH WITH
GALES IN EFFECT TONIGHT INTO FRIDAY NIGHT AND EARLY SATURDAY.
