AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
343 PM EDT TUE AUG 14 2012
.SYNOPSIS...
LOW PRESSURE AND ITS ENSUING FRONTAL BOUNDARY WILL MOVE THROUGH LATE
WEDNESDAY MORNING. HIGH PRESSURE SHOULD MOVE BACK IN BEHIND THE
DEPARTING SYSTEM LATE WEDNESDAY AND THURSDAY. ANOTHER COLD FRONT
SLOWLY MOVES THROUGH LATER ON FRIDAY INTO SATURDAY BEFORE HIGH
PRESSURE CAN POSSIBLY BUILD BACK IN LATE SUNDAY AND MONDAY.
&&
.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
SCATTERED SHOWERS AND TSTMS REMAIN ACROSS THE NJ SHORE AREAS AND
ALONG PARTS OF THE DELMARVA AS OF THE MID-AFTERNOON. CLOUD COVER HAS
LIMITED THE HEATING ACROSS THE AREA THIS AFTERNOON SO WIDESPREAD
TSTMS HAVE NOT DEVELOPED ACROSS THE AREA. THERE IS STILL THE CHC FOR
MORE TSTMS THIS EVENING AND OVERNIGHT...SO POPS HAVE BEEN KEPT IN
THERE FOR NOW. THE HIGHEST POPS WERE PLACED ACROSS THE WRN
AREAS...WHERE ACTIVITY MAY MOVE INTO LATER THIS EVENING AND OVER THE
DELMARVA...NORTH OF THE CURRENT ACTIVITY.
IT WILL REMAIN WARM AND HUMID TONIGHT WITH LOWS MOSTLY IN THE UPPER
60S TO LOW 70S. WINDS SHOULD MOSTLY BE SERLY OR SRLY AT 5 TO 10 MPH.
&&
.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH 6 PM WEDNESDAY/...
THE UPPER TROUGH WILL BE CROSSING THE AREA WED. MOISTURE WILL REMAIN
RATHER HIGH AND WITH THE FRONT AND WEAK LOW NEARBY...THERE REMAINS
THE CHC FOR SCATTERED SHOWERS/TSTMS. WE HAVE KEPT THE CHC FOR PRECIP
MOSTLY IN THE CHC RANGE FOR NOW. SPC HAS MOST OF OUR AREA IN A
GENERAL TSTM OUTLOOK...BUT SLGT CHC EXISTS OVER SRN DELAWARE. HIGH
TEMPERATURES WEDNESDAY WILL TOP OUT IN THE LOW 80S ACROSS THE NORTH
AND MID TO UPPER 80S ELSEWHERE.
&&
.LONG TERM /WEDNESDAY NIGHT THROUGH TUESDAY/...
A DOWNWARD TREND IN SHOWERY ACTIVITY IS EXPECTED DURING THE
OVERNIGHT HOURS WEDNESDAY AS THE FINAL MID-LEVEL IMPULSE PULLS
THROUGH AND TO OUR NORTHEAST. WEAK MID-LEVEL RIDGING WILL BUILD IN
ALLOWING MID-LEVELS WINDS TO BECOME SOMEWHAT ZONAL OR SLIGHTLY
NORTHWEST ON THURSDAY AND FRIDAY. SURFACE HIGH PRESSURE WILL MOVE
ACROSS THE REGION ON THURSDAY INTO EARLY FRIDAY AND KEEP OUR
SENSIBLE WEATHER RATHER QUIET. SHOULD HAVE AMPLE SUNSHINE ON
THURSDAY TO ALLOW TEMPERATURES TO CLIMB BACK TO AROUND SEASONAL OR
SLIGHTLY ABOVE.
HIGH SLIDES OFF THE COAST EARLY ON FRIDAY WITH A RETURN FLOW SETTING
UP. MORE MOISTURE AND WARMER TEMPERATURES ARE ADVECTED BACK INTO THE
REGION JUST IN TIME FOR AN APPROACHING MID-LEVEL WAVE AND SURFACE
COLD FRONT TO MOVE THROUGH. COULD SEE A LEE SIDE TROUGH FORM AND
MOVE THROUGH OUR SOUTHERN ZONES DURING THE AFTERNOON HOURS AND WITH
AMPLE SURFACE BASED INSTABILITY CONVECTION IS LIKELY, ALTHOUGH THIS
ALL DEPENDENT ON THE TIMING OF THE AFOREMENTIONED COLD FRONT AND LEE
SIDE TROUGH. MODEL TIMING ON THE FRONTAL PASSAGE HAS NOT BEEN GOOD
WITH SOME BRINGING IT THROUGH FRIDAY EVENING AND SOME NOT CLEARING
THE REGION UNTIL SUNDAY MORNING. THOUGH THE FLOW IN THE MID-LEVELS
DOES NOT LOOK AS FORCEFUL AS IT DID YESTERDAY, WITH A MORE
MERIDIONAL REGIME IN PLACE, A SLOWER TIMING LOOKS MORE LIKELY. THIS
WOULD INTRODUCE HIGHER CHANCES OF SHOWERS AND THUNDERSTORMS BY
FRIDAY EVENING/NIGHT SPREADING INTO SATURDAY EVENING. ANOTHER WAVE
OF LOW PRESSURE FORMS ALONG THE FRONTAL BOUNDARY AND SLOWS ITS
EASTWARD MOVEMENT EVEN MORE. THAT BEING SAID DECIDED TO KEEP THE
CHANCE POPS IN FOR MUCH OF SATURDAY.
FINALLY WE SHOULD BE ABLE TO KICK THE FRONT FAR ENOUGH TO THE EAST
BY LATE SATURDAY OR SUNDAY MORNING AND DRY OUT. MID-LEVEL TROUGHING
WILL REMAIN ACROSS THE REGION FOR THE DURATION OF THE LONGTERM AND
THIS COULD KEEP US RATHER UNSETTLED FOR THE START OF THE NEW WORK
WEEK. LOOKS LIKE OUR NEXT SHOT AT SEEING PRECIPITATION IS ON TUESDAY
AS ANOTHER PIECE OF ENERGY IN THE MID-LEVELS DIVES INTO THE BASE OF
THE EAST COAST TROUGH AND THEN MOVES UP TO THE NORTHEAST WITHIN THE
SOUTHWEST FLOW ALOFT.
TEMPERATURES THROUGH THE LONGTERM WILL BE NEAR NORMAL TO SLIGHTLY
ABOVE NORMAL BY THE END OF THE WEEK. ONCE THE MID-LEVEL TROUGH
RE-ESTABLISHES ITSELF NEARBY AND THE FRONTAL SYSTEM CLOSE BY, WE
COULD SEE AMPLE CLOUD COVER ALLOWING FOR SLIGHTLY BELOW NORMAL
TEMPERATURES SATURDAY THROUGH TUESDAY.
&&
.AVIATION /19Z TUESDAY THROUGH SUNDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY AND SURROUNDING AREAS.
THE FIRST BATCH OF SHOWERS THAT AFFECTED MOST OF SE PA AND NJ
EARLIER TODAY HAS MOVED TO THE COAST AND REMAIN NEAR KACY AS OF THE
EARLY AFTERNOON. OTHER SHOWERS/TSTMS ARE DEVELOPING OVER THE
DELMARVA AND MOVING SLOWLY NORTH-NORTHEAST. CONDITIONS WILL REMAIN
FAVORABLE FOR SHOWERS/SCT TSTMS TONIGHT AND WEDNESDAY. CONFID IN
EXACT TIMING/PLACEMENT IS LOW...SO PLENTY OF VCSH WAS PLACED IN THE
TERMINALS AND AMDS WILL BE ISSUED WHEN CONFID INCREASES. PATCHY FOG
WILL DEVELOP TONIGHT...SINCE MOST TERMINALS HAD SOME RAIN TODAY.
MOST AREAS WILL DROP TO MVFR IN THE FOG...BUT IFR CANT BE RULED OUT
IF DECENT RADIATIONAL COOLING HAPPENS.
OUTLOOK...
WEDNESDAY NIGHT THROUGH FRIDAY...MAINLY VFR WITH LIGHT WEST WINDS.
COULD BE SOME LOCAL MVFR VSBYS EARLY THURSDAY MORNING.
FRIDAY NIGHT THROUGH SATURDAY...ISOLATED TO SCATTERED SHOWERS AND
THUNDERSTORMS POSSIBLE. VFR CONDITIONS EXPECTED.
SATURDAY NIGHT THROUGH SUNDAY...VFR EXPECTED. COULD BE A FEW
LINGERING SHOWERS EARLY SATURDAY NIGHT.
&&
.MARINE..
A COLD FRONT WILL CROSS THE WATERS TONIGHT WHILE A WEAK AREA OF LOW
PRESSURE MOVES ALONG IT. THESE FEATURES WILL KEEP THE POSSIBILITY
FOR SCATTERED SHOWERS AND A FEW TSTMS FOR TONIGHT AND WEDNESDAY.
WINDS AND SEAS ARE EXPECTED TO REMAIN BELOW SCA CRITERIA...BUT
LOCALLY HIGHER WINDS AND SEAS CAN BE EXPECTED NEAR TSTMS. WINDS ON
THE WATERS WILL MOSTLY BE SRLY OR SERLY AT 10 TO 15 KTS WITH SOME
GUSTS TO AROUND 20 KTS OVER THE OCEAN WATERS.
OUTLOOK...
SUB-ADVISORY CONDITIONS ARE EXPECTED ACROSS THE WATERS
THROUGH THE WEEKEND. HIGH PRESSURE WILL BUILD IN ON THURSDAY
PROVIDING TRANQUIL CONDITIONS. WINDS TURN TO THE SOUTH ON FRIDAY
AND SEAS WILL BEGIN TO CLIMB TO 3 TO 4 FEET FOR A TIME DURING THE
AFTERNOON HOURS...DEPENDING ON HOW LONG WE TRULY KEEP THE
SOUTHERLY FETCH. ANOTHER FRONTAL SYSTEM TRIES TO ENTER FROM THE
WEST EARLY ON SATURDAY PROVIDING MORE SHOWERS AND THUNDERSTORMS.
THIS FRONT SHOULD THEN PUSH OFF TO THE EAST BY LATE IN THE DAY AND
WINDS TURN TOWARDS THE WEST-NORTHWEST.
