AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
652 PM EDT FRI JUN 17 2011
.SYNOPSIS...
A WEAK COOL FRONT IS CRAWLING SOUTHEASTWARD FROM PENNSYLVANIA AND
MAY NOT MOVE COMPLETELY PASS SOUTH OF OUR AREA UNTIL SUNDAY MORNING
AS LOW PRESSURE DRIFTS EAST FROM THE DELMARVA. A STRONG LOW
PRESSURE SYSTEM IN THE PLAIN STATES WILL LIFT TOWARD THE GREAT
LAKES DURING THE MIDDLE OF NEXT WEEK, LIFTING A WARM FRONT THROUGH
OUR AREA WEDNESDAY, FOLLOWED BY A COLD FRONT BY THE END OF THE
WEEK.
&&
.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
A MID/UPPER LOW WILL CONTINUE TO FLATTEN OUT AS IT MOVES THROUGH THE
AREA LATE THIS AFTERNOON/EVENING. A SURFACE FRONTAL BOUNDARY WILL
SLOWLY CROSS THE AREA TONIGHT, THEN IS EXPECTED TO BEGIN TO STALL TO
OUR SOUTH. SHOWERS AND THUNDERSTORMS HAVE DEVELOPED THIS AFTERNOON
AS THE TEMPERATURES WARMED AND THE MID/UPPER LOW CONTINUES TO MOVE
EASTWARD. PW VALUES ARE AROUND 1.5 INCHES, AND THERE IS A LITTLE BIT
OF INSTABILITY AND SHEAR, SO ANY SHOWERS/THUNDERSTORMS ACROSS THE
AREA COULD CONTAIN FREQUENT LIGHTNING, GUSTY WINDS, SMALL HAIL, AND
HEAVY RAIN. WE ARE NOT EXPECTING ANY SEVERE STORMS OR FLASH
FLOODING, BUT THE USUAL STREET AND POOR DRAINAGE FLOODING IS
POSSIBLE IN THE HEAVIEST DOWNPOURS. MOS TEMPERATURES WERE CLOSE TO
EACH OTHER, SO WE TOOK A BLEND OF THE TWO.
&&
.SHORT TERM /6 AM SATURDAY MORNING THROUGH SUNDAY/...
THE FORECAST FOR THE WEEKEND INTO EARLY NEXT WEEK SEEMS TO BE
UNSETTLED AND A LITTLE UNCERTAIN AT THIS TIME. THE AFOREMENTIONED
FRONTAL BOUNDARY IS EXPECTED TO STALL TO OUR SOUTH THIS WEEKEND,
WHILE A COUPLE OF WAVES OF LOW PRESSURE ARE EXPECTED TO DEVELOP
ALONG THE BOUNDARY AND MOVE TOWARD THE AREA. COINCIDENTALLY, SEVERAL
SHORTWAVES ARE EXPECTED TO MOVE ACROSS THE AREA AS WELL, WHICH COULD
LEAD TO AN UNSETTLED PERIOD. HOWEVER, THE MODELS ARE NOT GIVING US
VERY GOOD CONSENSUS ON TIMING AND PLACEMENT FOR SOME OF THE
FEATURES.
SATURDAY MAY BE THE DRIEST DAY, AS THERE IS NOT ANY STRONG
SHORTWAVES EXPECTED IN THE NORTHWEST FLOW ALOFT. HOWEVER, WE DID
DECIDE TO INCLUDE A SLIGHT CHANCE AS THERE WILL BE SOME INSTABILITY
AND PW VALUES WILL BE AROUND 1 TO 1.5 INCHES, SO WE MAY GET AN
ISOLATED SHOWER/THUNDERSTORM. FOR TEMPERATURES, WE TOOK A BLEND OF
THE MAV/MET MOS AS THEY WERE PRETTY CLOSE, BUT WEIGHTED MORE TOWARD
THE HIGHER MAV MOS.
FOR SATURDAY NIGHT INTO SUNDAY, THE GFS IS A LITTLE FASTER WITH THE
SHORTWAVE AND SURFACE LOW PRESSURE RIDING ALONG THE FRONTAL BOUNDARY
THAN MOST OF THE OTHER MODELS. MOST OF THE MODELS DO AGREE THAT
THERE IS A CHANCE OF PRECIPITATION, ESPECIALLY FOR OUR SOUTHERN
AREAS SATURDAY NIGHT INTO SUNDAY AS THE FIRST LOW MOVES JUST TO OUR
SOUTH. AGAIN TEMPERATURE WISE, WE TOOK A A BLEND OF THE MAV/MET
MOS, BUT WEIGHTED MORE TOWARD THE HIGHER MAV MOS.
FOR SUNDAY NIGHT INTO MONDAY, ANOTHER SHORTWAVE AND SURFACE LOW
PRESSURE SYSTEM WILL CROSS THE AREA. JUST LIKE THE PREVIOUS 24 HOUR
PERIOD, MOST MODELS AGREE THAT THERE IS A CHANCE OF PRECIPITATION
FOR MUCH OF THE AREA, BUT THE LOW MAY CROSS CLOSER TO OUR AREA, OR
RIGHT OVER, SO THE BEST CHANCE MAY BE EVERYWHERE. WE WENT PRETTY
CLOSE TO GFS MOS FOR TEMPERATURES ON MONDAY, WHICH IS PRETTY CLOSE
TO WHAT MODEL 850 MB TEMPERATURES WOULD TRANSLATE TO ACROSS THE AREA.
&&
.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
THE UPPER PATTERN IN THE LONG TERM WILL FEATURE RIDGING OVER THE
SERN CONUS GIVING WAY TO SOME TROUGHING OVER THE NE USA NEXT
WEEKEND.
THIS EXTENDED PERIOD WILL AVERAGE WARMER THAN NORMAL FOR LATE JUNE
WITH THE HOTTEST DAY IN THIS SCENARIO CURRENTLY EXPECTED TO BE NEXT
THURSDAY WHEN MAX TEMPS IN THE VALLEYS AND COASTAL PLAIN AWAY FROM
WATER SHOULD REACH THE LOW TO MID 90S.
THE PATTERN IS SOMEWHAT UNSTABLE AND IT WAS DIFFICULT TO
DIFFERENTIATE BEST CHANCE FOR CONVECTION WITH THE MULTITUDE OF
DISTURBANCES ALOFT AND ASSOCIATED PIECES OF W AND CAA IN THE LOW
LVLS. THERE IS BASICALLY A CHANCE POP EVERYDAY.
THE DAILIES...
MON NIGHT...LESS THAN AVERAGE CONFIDENCE ON POPS AND WIND DIRECTION.
A WEAK FRONT IN THE MID ATLC STATES MAY BE PRODUCING THUNDERSTORMS.
TUESDAY...12Z EC AND GFS DIFFER. RAISED THE HPC POP GUIDANCE A BIT
CLOSER TO THE 12Z EC BUT WITH LESS THAN AVG CONFIDENCE. SAME WEAK
FRONTAL SYSTEM IN THE AREA. IT COULD BE GENERATING A PERIOD OF
TSTMS.
WEDNESDAY...WAA AND A CHANCE FOR TSTMS AS IT APPEARS MORE UNSTABLE
ARRIVES FROM THE W.
THURSDAY...LOOKS HOT AND HUMID WITH ANY PREDAWN TSTMS TEMPORARILY
DISSIPATING OR PUSHING OUT TO SEA. THE HEAT INDEX SHOULD RISE INTO
THE 95-100 RANGE FROM KTTN SOUTHWESTWARD AND COULD SEE THE NEED FOR
AT LEAST AN URBAN HEAT ADVISORY. AN APPROACHING COOL FRONT SHOULD
SPAWN TSTMS THAT CROSS OUR AREA IN THE AFTN OR NIGHT. CONFIDENCE ON
TEMPS ABV AVG AND CONFIDENCE ON POPS AVG.
FRIDAY...THE INITIAL COOL FRONT MAY DIE OUT AT THE EXPENSE OF ONE
MORE SHORT WAVE DEPARTING THE WESTERN GREAT LAKES FRI MORNING AND
FORMING A NEW COOL FRONT IN THE APPS THAT IF OCCURS...WOULD BE A
TSTM GENERATOR.
&&
.AVIATION /00Z SATURDAY THROUGH WEDNESDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY AND SURROUNDING AREAS.
651PM UPDATE.
REST OF TONIGHT...VFR WITH ISOLATED TSTMS G30 KT AND R+ POSSIBLE
PEA SIZE HAIL. MOST OF THE STORMS SHOULD BE OCCURRING IN E MD AND
DEL BETWEEN NOW AND 5Z. PATCHY MVFR F IS POSSIBLY TOWARD MORNING
AT THE COUNTRYSIDE TAF LOCATIONS. LIGHT WIND.
SATURDAY...VFR. LIGHT WINDS WITH AFTERNOON SEA-BAYBREEZES VCNTY KMIV
KACY KILG.
OUTLOOK...
VFR DRY WEATHER IS EXPECTED FOR SATURDAY EVENING. THERE IS A
CHANCE FOR SHOWERS AND THUNDERSTORMS FROM LATE SATURDAY NIGHT INTO
SUNDAY AS ANOTHER WEATHER SYSTEM DROPS INTO OUR REGION FROM THE
NORTHWEST. WEAK HIGH PRESSURE IS ANTICIPATED TO BRING MAINLY DRY
WEATHER FOR MONDAY AND TUESDAY. CONVECTION-RELATED, LATE NIGHT AND
EARLY MORNING VISIBILITY RESTRICTIONS ARE POSSIBLE EACH DAY.
&&
.MARINE...
OTHER THAN MWS FOR CONVECTION THIS EVENING...NO HEADLINES.
THE PRESENT MID LEVEL LOW AND ASSOCIATED SURFACE FRONT WILL MOVE
EAST OVERNIGHT. CONVECTION IS POSSIBLE IN ADVANCE OF THE SYSTEM.
OUTSIDE OF CONVECTION, WINDS AND WAVES ARE EXPECTED TO REMAIN BELOW
ADVISORY CRITERIA. AFTER THAT, ALTHOUGH WEAK LOW PRESSURE SYSTEMS
WILL PASS EITHER OVER OR JUST SOUTH OF THE SOUTHERN WATERS ON SUNDAY
AND MONDAY, CONDITIONS ARE EXPECTED TO REMAIN SUB-ADVISORY THROUGH
THE FORECAST (ALTHOUGH BOATING CONDITIONS WON'T BE IDEAL, AS
CONVECTION IS AGAIN POSSIBLE WITH EACH).
&&
.TIDES/COASTAL FLOODING...
BASED ON VARIOUS GUIDANCE, THERE ISN'T SUFFICIENT EVIDENCE TO ISSUE
ANY COASTAL FLOOD PRODUCTS FOR THE NEXT HIGH TIDE CYCLE (LATE THIS
EVENING INTO THE OVERNIGHT PERIOD FROM THE ATLANTIC COAST UP TO THE
TIDAL DELAWARE RIVER AND SATURDAY MORNING ALONG CHESAPEAKE BAY). WE
WILL CONTINUE TO MONITOR THE TIDES, BUT ANY UNEXPECTED FLOODING
WOULD BE QUITE MINOR IN NATURE.
