Hail and Damaging Winds in Pennsylvania, August 1, 2011

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
340 PM EDT MON AUG 1 2011

.SYNOPSIS...
A WEAKENING COLD FRONT WILL CONTINUE TO SLOWLY SAG THROUGH THE
REGION THIS EVENING INTO THE OVERNIGHT HOURS. ANOTHER COLD FRONT
WILL PUSH THROUGH ON WEDNESDAY AND BRING ANOTHER ROUND OF UNSETTLED
WEATHER TO THE REGION. HIGH PRESSURE RETURNS ON THURSDAY THROUGH A
BETTER PART OF SATURDAY. THIS IS WHEN ANOTHER COLD FRONT MOVING IN
FROM THE NORTHWEST WILL SWEEP THROUGH.

&&

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
AN 18Z ANALYSIS SHOWS WEAK COLD FRONT STILL DRAPED ACROSS THE
SOUTHERN PORTIONS OF NEW YORK STATE INTO CENTRAL PENNSYLVANIA AND
FINALLY STRETCHING BACK INTO THE GREAT LAKES REGION. A RATHER LARGE
MCS CONTINUES TO MOVE SOUTHEASTWARD THROUGH THE UPPER MID-WEST AND
WESTERN GREAT LAKES...THIS WILL COME INTO PLAY ON WEDNESDAY.

CONVECTION JUST UPSTREAM WILL SLOWLY ADVECT INTO OUR NORTHERN
ZONES OVER THE NEXT COUPLE OF HOURS. ISOLATED SUPERCELLS ACROSS
NORTHEASTERN PENNSYLVANIA WERE TIED WITH THE LEAD SHORTWAVE TROUGH
OF LOW PRESSURE PUSHING AHEAD OF THE ENSUING COLD FRONT. WITH
CONVECTIVE TEMPERATURES BEING MET OR EXCEEDED ACROSS A BROAD AREA
HAVE PRODUCED A STRENGTHENING CUMULUS FIELD. A FEW DISCRETE CELLS
HAVE FOUND SOME LIFT ALONG THE BAY BREEZE OR WEAK SURFACE TROUGH
AROUND THE PHILADELPHIA METRO AREA. EFFECTIVE BULK SHEAR ACROSS THE
SOUTHERN HALF OF OUR CWA IS RATHER ROBUST, AT LEAST BASED OFF THE
RUC ANALYSIS, BETWEEN 25 TO 30 KNOTS WHILE OVER THE NORTH IT IS LESS
THAN 15 KNOTS. SURPRISINGLY THE NORTHERN HALF OF THE CWA WILL BE
UNDER THE GUN THE MOST AS MULTICELL CLUSTERS PUSH DOWN AHEAD OF THE
SURFACE FRONT FROM THE NORTHWEST.

THESE STORMS COULD PRODUCE DAMAGING WINDS, LARGE HAIL AND VERY HEAVY
RAINFALL AS THEY MOVE TO THE SOUTHEAST AT AROUND 15 KNOTS. LAPS
SOUNDINGS FROM AROUND THE REGION SHOW DRIER AIR IN THE MID-LEVELS,
CORRESPONDING TO THE NORTHWEST FLOW, AS THE LOW-LEVELS SHOW WEAK
MOISTURE ADVECTION FROM THE WEST. THIS DEPICTS AN INVERTED V-FEATURE
ON THE SOUNDING WHICH IS NOTORIOUS FOR VERY STRONG, POSSIBLY
DAMAGING WINDS AND LARGE HAIL. BOTH LOW AND MID-LEVEL LAPSE RATES
SUPPORT THE THINKING THAT THE MAIN THREATS FOR THIS EVENING WOULD BE
WIND AND HAIL.

THE ONLY SAVING GRACE TODAY AS BEEN THE DRIER AIR MIXING DOWN ALL
AFTERNOON AND THE FACT THAT THE SURFACE WINDS HAVE BEEN MORE
WESTERLY AHEAD OF THE FRONT. WE ARE NOT EXPECTING MUCH IN THE WAY OF
CONVECTION FIRING UP PRIOR TO THE COLD FRONT PASSAGE...JUST WAITING
FOR THE UPSTREAM STORMS TO MOVE INTO OUR REGION.

ONCE THE FRONT MOVES THROUGH LATER TONIGHT WE WILL SEE A CLEARING
TREND FROM NORTHWEST TO SOUTHEAST. A FRESH AIRMASS TAKES A WHILE TO
FINALLY WORKS ITS WAY INTO THE REGION TONIGHT SO WE ARE NOT
EXPECTING DEWPOINTS TO DROP MUCH IN THE WAKE OF THE WEAK COLD AIR
ADVECTION.

&&

.SHORT TERM /6 AM TUESDAY MORNING THROUGH THURSDAY/...
WITH THE COLD FRONT TO OUR SOUTH TUESDAY MORNING A VERY BRIEF SHOT
OF HIGH PRESSURE WILL MOVE INTO THE REGION DURING THE DAY. THE
MID-LEVEL PARENT LOW PRESSURE OVER THE GREAT LAKES WILL DRIFT
TOWARDS THE EAST AND BEGIN TO DROP MID-LEVEL HEIGHTS A BIT ACROSS
OUR REGION. WEAK COLD AIR ADVECTION KICKS IN BUT AGAIN THIS WILL BE
SHORT LIVED AS THE SURFACE AND LOW-LEVEL FLOW BEGINS TO TURN MORE
TOWARDS THE WEST. TUESDAY SHOULD BE A PRECIPITATION FREE DAY WITH
THE HIGH PRESSURE OVERHEAD.

THE MCS MENTIONED IN THE NEAR TERM WILL CONTINUE ITS SOUTHEASTWARD
PROGRESSION ON TUESDAY AND WEDNESDAY. THE MOST LIKELY TIMEFRAME FOR
THIS MCS WILL BE WEDNESDAY LATE MORNING THROUGH THE AFTERNOON HOURS.
THE GFS AND ECMWF MODELS APPEARED TO HAVE A BETTER HANDLE ON THE
MOVEMENT OF THIS MCS INTO OUR REGION. WITH REGARDS TO SENSIBLE
WEATHER, CLOUDS WILL BE ON THE INCREASE BY WEDNESDAY MORNING WITH
MOSTLY CLOUDY TO OVERCAST SKIES LASTING THROUGH WEDNESDAY. VERY
HEAVY RAINFALL IS ALSO EXPECTED FROM THIS SYSTEM AND DEPENDING ON
THE SIZE OF THE SYSTEM, A LOT OF AREAS COULD SEE A GENEROUS AMOUNT
OF RAIN ON WEDNESDAY. AS A RESULT WE HAVE BOUGHT THE GUIDANCE SUGGESTING
COOLER TEMPERATURES ACROSS THE REGION. WEDNESDAY NIGHT CLOUDS
SHOULD BEGIN TO CLEAR AS THE SYSTEM DEPARTS THE REGION SETTING THE
STAGE FOR A DRY AND SEASONABLE THURSDAY.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
FOR THIS EXTENDED FORECAST PERIOD...IN GENERAL THE UPPER RIDGE
PATTERN HOLDS OVER THE CENTRAL U.S. WITH  W-NW FLOW ALOFT OVER THE
NORTHEAST AND MID ATLANTIC REGIONS. HWVR...BOTH THE GFS AND ECMFW
SUGGEST THE UPPER RIDGE MAY WEAKEN SMWHT TOWARDS THE BEGINNING OF
NEXT WEEK.

HIGH PRESSURE WILL DOMINATE MUCH OF THE TIME...ALTHO LOW PRESSURE IS
FCST TO MOVE EWD ACROSS NY STATE SATURDAY AND SATURDAY NIGTH AND
INTO NEW ENGLAND BY SUN. THE TRAILING FRONTAL SYSTEM WILL BRING AN
INCREASED CHANCE OF T-STORMS ON SAT INTO SAT NIGHT...WITH PERHAPS
SOME LINGERING CNVTN EARLY SUN MORNING OVER THE DELMARVA REGION. AT
THIS LONGER RANGE OF COURSE CONFIDENCE IN THE TIMING FOR PRECIP IS
NOT VERY HIGH...BUT SAT OR SAT NIGHT LOOK LIKE THE BEST CHANCE FOR
RAIN.

TEMPERATURES DURING THIS PERIOD WILL BE NEAR TO SLIGHTLY ABOVE
NORMAL FOR THIS TIME OF YEAR.

&&

.AVIATION /20Z MONDAY THROUGH SATURDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY AND SURROUNDING AREAS.

THE MAIN FORECAST CHALLENGE IS THE EXTENT OF SHOWERS AND
THUNDERSTORMS ACROSS THE REGION THROUGH ABOUT MID TO LATE THIS
EVENING. A COLD FRONT WILL MOVE INTO THE AREA TOWARD EVENING THEN
SHIFT TO OUR EAST TONIGHT. SHOWERS AND THUNDERSTORMS ARE DEVELOPING
JUST TO OUR NORTHWEST AND THIS ACTIVITY WILL CONTINUE TO SPREAD
SOUTHEASTWARD. WHILE ISOLATED SHOWERS/STORMS HAVE DEVELOPED
AHEAD OF THIS WITH A WIND SHIFT LINE, IT APPEARS WE WILL HAVE TO
WAIT FOR ANY MORE ORGANIZE ACTIVITY TO MOVE INTO THE AREA FROM THE
NORTHWEST. FOR NOW, WE CARRIED A VCSH AND A CB DESCRIPTOR FROM WEST
TO EAST AND WE WILL MONITOR RADAR TRENDS AND ISSUE AMENDMENTS WHEN
SHOWERS/STORMS HAVE A BETTER CHANCE OF IMPACTING A TERMINAL. SOME
STORMS COULD BE LOCALLY GUSTY AND SOME SUB-VFR CONDITIONS WILL OCCUR
FOR A BRIEF TIME.

SOUTHWEST TO WEST WINDS TO ABOUT 10 KNOTS THIS AFTERNOON WILL SHIFT
TO THE WEST AND NORTHWEST. THESE WINDS ARE EXPECTED TO DIMINISH
TONIGHT, BUT ANY TERMINAL THAT HOLDS ONTO SOME WIND SHOULD MAINTAIN
A NORTHWEST DIRECTION. ANY SHOWERS AND THUNDERSTORMS ARE EXPECTED TO
END FROM NORTHWEST TO SOUTHEAST DURING THE FIRST HALF OF THE NIGHT
ALONG WITH CLOUDS ON THE WANE. LIGHT WINDS AND LESS CLOUDS MAY ALLOW
PATCHY FOG TO DEVELOP OVERNIGHT, ESPECIALLY WHERE ANY HEAVIER RAIN
OCCURRED ALLOWING THE LOW-LEVEL MOISTURE TO REMAIN ELEVATED LONGER.
FOR NOW, JUST HINTED AT THIS AT KTTN AND KMIV LATE.

FOR TUESDAY, ANY PATCHY FOG WILL DISSIPATE EARLY THEN A NORTHWEST
WIND WILL INCREASE TO ABOUT 10 KNOTS. THERE COULD BE SOME LOCAL
GUSTINESS IN THE AFTERNOON, HOWEVER THIS APPEARS TO NOT BE MUCH
HIGHER THAN THE SUSTAINED WINDS SO IT WAS NOT INCLUDED AT THIS TIME.
THE AIRMASS DRIES OUT SOME AND WITH ENOUGH MIXING CUMULUS DEVELOPMENT
SHOULD BECOME FEW TO SCATTERED.

OUTLOOK...
TUESDAY AND WEDNESDAY...A WARM FRONT GENERALLY TO OUR SOUTH WITH A
DISTURBANCE TRACKING ALONG IT. IT APPEARS THAT A CLUSTER OF SHOWERS
AND THUNDERSTORMS WILL MOVE INTO OUR AREA LATER TUESDAY NIGHT FROM
THE NORTHWEST, HOWEVER THERE IS SOME UNCERTAINTY ON EXACTLY WHERE
THE MORE ORGANIZED ACTIVITY TRACKS. THERE COULD BE A PERIOD OF
SUB-VFR CONDITIONS ASSOCIATED WITH LOWER CEILINGS AND ALSO HEAVIER
RAIN. THE MOST CONCENTRATED ACTIVITY MAY THIN OR MOVE OUT OF THE
AREA BY MID MORNING WEDNESDAY.

THURSDAY AND FRIDAY...VFR WITH HIGH PRESSURE ACROSS THE AREA. CLOUDS
MAY INCREASE LATE FRIDAY THOUGH.

SATURDAY...A FRONTAL BOUNDARY APPROACHES WITH THE CHANCE FOR SOME
SHOWERS AND THUNDERSTORMS, ESPECIALLY IN THE AFTERNOON AND EVENING.
VFR WITH THE EXCEPTION IN CONVECTION.

&&

.MARINE...
A COLD FRONT WILL MOVE THROUGH THE AREA TONIGHT. SOME SHOWERS AND
THUNDERSTORMS ARE EXPECTED TO ARRIVE ALONG AND AHEAD OF THIS FRONT
THROUGH ABOUT MIDNIGHT. SOME STORMS COULD BE STRONG WITH LOCALLY
GUSTY WINDS AND HEAVY RAIN. THIS ACTIVITY IS THEN EXPECTED TO MOVE
TO THE EAST OVERNIGHT AS THE FRONT SETTLES SOUTHEASTWARD. THE
SOUTHERLY FLOW AHEAD OF THIS FRONT WILL INCREASE A BIT BUT IS
EXPECTED TO REMAIN BELOW SMALL CRAFT ADVISORY CRITERIA.

THE FRONT THEN STALLS JUST TO OUR SOUTH TUESDAY WITH A WAVE OF LOW
PRESSURE TRACKING ALONG IT LATER TUESDAY NIGHT AND WEDNESDAY. THIS
MAY BRING A ROUND OF SHOWERS AND THUNDERSTORMS ACROSS THE AREA
DURING THIS TIME. THE SURFACE FLOW WILL TURN FROM NORTHWEST TO
SOUTHWEST, THEN FROM THE NORTHEAST WEDNESDAY. DEPENDING ON WHERE THE
WARM FRONT SITS WILL DETERMINE THE WIND DIRECTION AND ATTM WE PLACED
THIS CLOSE TO THE SOUTHERN ZONES. HIGH PRESSURE BUILDS IN FOR
THURSDAY AND FRIDAY, HOWEVER SOMEWHAT OF A NORTHEASTERLY SURGE MAY
OCCUR THURSDAY. THE NAM/WRF APPEARS TO BE A BIT TO STRONG WITH THIS,
SO WE KEPT WINDS JUST UNDER SMALL CRAFT ADVISORY CRITERIA. A WARM
FRONT THEN ARRIVES LATE FRIDAY WITH THE NEXT COLD FRONT SCHEDULED TO
ARRIVE LATER SATURDAY.
