AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
153 PM EDT TUE JUN 9 2009
.SYNOPSIS...
A FRONT WILL APPROACH FROM THE WEST THIS AFTERNOON AND BECOME
STATIONARY IN OUR REGION TONIGHT INTO WEDNESDAY. THIS FRONT SHOULD
LIFT NORTHWARD AS A WARM FRONT LATER WEDNESDAY INTO THURSDAY AS LOW
PRESSURE NEARS OUR REGION. THIS LOW WILL CROSS THE AREA THURSDAY
INTO FRIDAY, WITH AN ASSOCIATED COLD FRONT FINALLY SWINGING THROUGH
OUR REGION FRIDAY MORNING. HIGH PRESSURE IS FORECAST TO BUILD
GRADUALLY TOWARD OUR REGION SATURDAY AND SUNDAY.
&&
.NEAR TERM /THROUGH TONIGHT/...
GRIDS AND ZONES HAVE BEEN UPDATED TO REFLECT SEVERE THUNDERSTORM
WATCH AND FLASH FLOOD WATCH.
WITH A LITTLE SUNSHINE AND ANOTHER APPROACHING AND (HOPEFULLY)
WEAKER SHORT WAVE, ALONG WITH QUITE UNSTABLE AIR AND HIGH DEW
POINTS THIS AFTERNOON...WE EXPECT REFORMATION OF SHOWERS AND
THUNDERSTORMS, AGAIN WITH THE POSSIBILITY OF SEVERE WEATHER.
IT LOOKS ON SATELLITE IMAGERY THAT AT LEAST SOME SUN WILL EMERGE
OVER WESTERN SECTIONS FOR A WHILE FOR EASTERN AND SOUTHEASTERN
AREAS, ONLY LIMITED SUN WAS MENTIONED.
TEMPERATURES WERE LOWERED A DEGREE OR TWO WHERE THEY WERE IN THE MID
80S OVER OUR CENTRAL ZONES AND THE INTERIOR DELMAR ZONES BASED ON
15Z READINGS AND AN EXPECTED MAJORITY OF CLOUDS.
&&
.SHORT TERM /WEDNESDAY THROUGH WEDNESDAY NIGHT/...
THE NAM HOLDS TOUGH WITH THE HIGH TO THE NORTHEAST AND THE ONSHORE
FLOW TONIGHT. THE GFS AND THE ECMWF DEVELOP A LOW NEAR THE
DELMARVA BY THE END OF THE NIGHT, AND SO ALSO EVENTUALLY DEVELOP
AN EASTERLY FLOW. THE THREE MODELS HAVE VARIOUS DEPICTIONS OF
ENERGY COMING OVER A WEAKLY BUILDING RIDGLET, AND WEVE BASICALLY
GONE WITH A PRECIP FORECAST THAT STARTS WITH ASSUMED PERSISTENCE
/FROM WHAT WE ARE FORECASTING FOR THE FIRST PERIOD/ AND ENDS WITH
CLIMATOLOGY /LOW POPS/. AGAIN, OUR TEMPERATURES LEAN MET NORTHEAST
AND THEN BLEND MET AND MAV MOVING FURTHER SOUTHWEST.
BY WEDNESDAY, WE WOULD LIKE TO FAVOR CLIMATOLOGY IN THAT IT WOULD
BE HARD TO KEEP THE WARM FRONT AT BAY WITH SUCH A HIGH SUN ANGLE
AND A PROGRESSIVE /SLOWLY PROGRESSIVE/ SURFACE HIGH TO THE
NORTHEAST, BUT SAID HIGH KEEPS GETTING STRONGER ON ALL MODELS. WE
COULDNT FIND A TRIGGER FOR CONVECTION AT THE MID LEVELS AND SO
OUR POPS ARE LOW FOR NOW, BUT WE DID GO CLOSE TO PERSISTENCE VIS A
VIS TODAY ON TEMPERATURES. WITH A SYSTEM APPROACHING FROM THE
WEST ON WEDNESDAY NIGHT, WE BROUGHT POPS BACK IN. THE NAM LOOKS
OVERDONE WITH THE STRENGTH OF THIS SYSTEM, SO WE DID NOT RAISE
MINIMUM TEMPERATURES BASED ON ITS STRONG H925 FLOW AT THIS POINT
BUT RATHER MAINTAINED CONTINUITY.
&&
.LONG TERM /THURSDAY THROUGH MONDAY/...
BY THURSDAY, THE WARM FRONT WILL BEGIN LIFTING BACK NORTHWARD,
WITH AN AREA OF LOW PRESSURE LIFTING TOWARD THE AREA OVERNIGHT
THURSDAY INTO FRIDAY. FINALLY THE COLD FRONT WILL MOVE THROUGH THE
AREA OVERNIGHT THURSDAY INTO FRIDAY. THIS WILL HELP TO KEEP A
CHANCE OF SHOWERS AND THUNDERSTORMS ACROSS THE AREA FROM THURSDAY
INTO FRIDAY. WE COULD SEE SOME STRONG STORMS DEPENDING OF THE
TRACK OF THE WARM FRONT AND LOW PRESSURE SYSTEM AND IF WE REMAIN
IN THE WARM SECTOR LONG ENOUGH. EITHER WAY, WE WILL LIKELY SEE
SOME HEAVY RAIN WITH SOME SHOWERS/THUNDERSTORMS.
BY LATE FRIDAY AND INTO THE WEEKEND, AFTER THE COLD FRONT MOVES
THROUGH, HIGH PRESSURE WILL BUILD IN. THIS WILL PROVIDE FOR A NICE
WEEKEND. WITHOUT ANY STRONG WARM OR COLD AIR ADVECTION, TEMPERATURES
SHOULD REMAIN COMFORTABLE. IN FACT, TEMPERATURES THROUGHOUT THE
EXTENDED ARE EXPECTED TO BE CLOSE TO AVERAGE FOR THIS TIME OF
YEAR.
&&
.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY AND SURROUNDING AREAS.
MORNING CONVECTION BROUGHT IFR CONDITIONS AND FLIGHT PROBLEMS /
DELAYS. A BREAK IS EXPECTED LATE THIS MORNING AND EARLY THIS
AFTERNOON, BUT THE DAMAGE MAY HAVE BEEN DONE AS MARGINAL VFR
CONDITIONS YET PREVAIL AT MOST SPOTS, EVEN REMAINING IFR AT KACY.
WITH THE FRONTAL BOUNDARY APPROACHING THE AREA FROM THE WEST ALONG
WITH A WEAKER UPPER SHORT WAVE, AND HIGH DEW POINTS AND A QUITE
UNSTABLE AIRMASS IN PLACE, ADDITIONAL SHOWERS AND THUNDERSTORMS ARE
EXPECTED LATER THIS AFTERNOON, WORKING EASTWARD INT HE 20Z-22Z TIME
FRAME.
THERE IS PLENTY OF MOISTURE IN THE ATMOSPHERE, THEREFORE LOCALLY
HEAVY RAIN WOULD TEND TO REDUCE THE VISIBILITY AT TIMES AND FREQUENT
LIGHTNING IS EXPECTED WITH MANY OF THE THUNDERSTORMS.
SHOWERS AND THUNDERSTORMS ARE EXPECTED TO CONTINUE FOR THIS EVENING,
THEN DIMINISH WITH TIME. A FRONTAL BOUNDARY LOOKS TO MEANDER IN OUR
VICINITY TONIGHT, AND THIS MAY TEND TO KEEP THE CLOUD BASES LOWER.
IF THE CEILINGS ARE ABLE TO IMPROVE, THEY MAY LOWER ONCE AGAIN IN
THE EVENING AS PLENTY OF LOW-LEVEL MOISTURE REMAINS.
OUTLOOK...
AREAS OF LOW CLOUDS AND FOG WILL BE POSSIBLE OVERNIGHT AND WEDNESDAY
MORNING AS A PESKY BOUNDARY LOOKS TO LINGERS NEAR OUR AREA. WE MAY
BE ABLE TO SQUEEZE IN A DRY DAY WEDNESDAY BEFORE THE NEXT LOW
PRESSURE SYSTEM MOVES IN FOR THURSDAY. THIS LOOKS TO BRING ANOTHER
ROUND OF SHOWERS AND THUNDERSTORMS THURSDAY INTO FRIDAY BEFORE A
COLD FRONT SETTLES TO OUR SOUTH AND EAST. HIGH PRESSURE THEN
GRADUALLY BUILDS TOWARD OUR AREA LATER FRIDAY AND SATURDAY.
&&
.MARINE...
A FRONTAL BOUNDARY IS NEARLY STALLED ACROSS OUR SOUTHERN WATERS WITH
AN EASTERLY FLOW TO ITS NORTH. WHILE THERE IS NO REAL STRONG
PRESSURE GRADIENT, THE PLACEMENT OF THE SURFACE BOUNDARY WILL GOVERN
THE WIND DIRECTION. THERE ARE DIFFERENCES AMONG THE COMPUTER MODELS
ON HOW FAR NORTH THIS BOUNDARY LIFTS THROUGH WEDNESDAY, AND WE ARE
LEANING MORE TOWARD THE SLOWER SOLUTION GIVEN THE MAIN SURFACE LOW
BEING FAR REMOVED FROM OUR AREA TODAY AND TONIGHT. THIS WILL KEEP AN
EASTERLY COMPONENT TO THE WIND LONGER ACROSS THE NORTHERN COASTAL
WATERS. WE ARE ANTICIPATING WINDS TO BE ABOUT 10 KNOTS GIVEN THE
FAIRLY WEAK PRESSURE GRADIENT THROUGH WEDNESDAY.
AS LOW PRESSURE APPROACHES ON THURSDAY THEN SLIDES NEARBY THURSDAY
NIGHT, THE LOW-LEVEL WIND FIELD IS FORECAST TO INCREASE FROM THE
SOUTH AND SOUTHWEST. THE FORECAST SOUNDINGS DO INDICATE A LOW-LEVEL
INVERSION HOLDING WITHIN THE WAA REGIME. THIS WOULD TEND TO LIMIT
THE STRONGER WINDS ALOFT FROM REACHING THE SURFACE. WE WILL CONTINUE
TO GO IN THIS DIRECTION. THE INCREASED FLOW THOUGH WILL BUILD THE
SEAS SOME, HOWEVER WAVEWATCH ONLY TOPS SEAS TO 5 FEET LATER THURSDAY
FOR A SHORT PERIOD OF TIME. FOR NOW, WE CONTINUED WITH THE IDEA OF
CAPPING THE SEAS AT 4 FEET GIVEN THE UNCERTAINTY WITH THE DETAILS
AND THE LACK OF A MUCH STRONGER GRADIENT. HOWEVER, WINDS AND SEAS
WILL BE LOCALLY HIGHER NEAR THUNDERSTORMS. THE SYSTEM LOOKS TO
FINALLY BE SLIDING TO OUR EAST FRIDAY MORNING WHICH WILL PULL A COLD
FRONT THROUGH. HIGH PRESSURE IS FORECAST TO GRADUALLY BUILD TOWARD
OUR AREA SATURDAY, HOWEVER A FRONTAL BOUNDARY MAY NOT BE TO FAR AWAY
TO OUR SOUTH. OVERALL, CONDITIONS CONTINUE TO BE FORECAST BELOW
SMALL CRAFT ADVISORY CRITERIA THROUGH THE PERIOD.

A WARM FRONT WILL TRACK NORTH THROUGH THE REGION THIS AFTERNOON. A COLD FRONT, ON THE HEELS OF THE WARM FRONT, WILL PUSH THROUGH TONIGHT. AS THESE FRONTS MOVE INTO THE MOIST AND UNSTABLE AIR OVER THE REGION, SCATTERED STRONG TO SEVERE THUNDERSTORMS ARE EXPECTED TO DEVELOP. LIKE THIS MORNING, THE THUNDERSTORMS THIS AFTERNOON AND EVENING ARE EXPECTED TO PRODUCE HAIL, FREQUENT CLOUD TO GROUND LIGHTNING, GUSTY WINDS, AND HEAVY RAIN. THE HEAVY RAIN COULD CAUSE WATER TO POND ON ROADS AND QUICKLY FILL ROADSIDE DITCHES AND SMALL STREAMS. IF A THUNDERSTORM APPROACHES YOUR AREA, MOVE INDOORS TO PROTECT YOURSELF FROM LIGHTNING. IF YOURE ON THE ROAD AND ENCOUNTER FLOODING, TURN AROUND IF POSSIBLE. JUST ONE FOOT OF FLOWING WATER IS POWERFUL ENOUGH TO SWEEP YOUR VEHICLE OFF THE ROAD.
