AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
337 PM EDT WED JUN 22 2011

.SYNOPSIS...
A LOW PRESSURE SYSTEM OVER THE NORTHERN MISSISSIPPI VALLEY REGION
THIS AFTERNOON WILL SLOWLY MOVE EASTWARD ACROSS THE GREAT LAKES
REGION TONIGHT THROUGH THURSDAY NIGHT. THE LOW WILL THEN MOVE
ACROSS SOUTHERN CANADA AND CAUSE A COLD FRONT TO MOVE EASTWARD
ACROSS OUR REGION. A WEAK AREA OF HIGH PRESSURE WILL AFFECT THE
REGION THIS WEEKEND. AN UPPER LEVEL LOW MAY BRING SOME SHOWERS TO
THE DELMARVA REGION LATER SUNDAY AND INTO EARLY NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
THE WARM FRONT THAT WAS ACROSS THE EARLIER HAS LIFTED TO THE NORTH
AND A VERY WARM AND HUMID AIRMASS HAS MOVED IN BEHIND IT. THE
ATMOSPHERE HAS HEATED SUFFICIENTLY ALREADY TO CREATE SHOWERS AND
THUNDERSTORMS ACROSS ERN PENNSYLVANIA AND MD ALSO. THESE
THUNDERSTORMS WILL CONTINUE TO FILL IN EARLY TONIGHT AS
INSTABILITY WILL ONLY SLOWLY DIMINISH. THE MAIN THREATS WITH ANY
THUNDERSTORMS TONIGHT WILL BE HEAVY RAINS AND GUSTY WINDS. THE
STORMS HAVE DECENT MOVEMENT TODAY SO WITH THE POSSIBILITY OF SLOW
MOVING THUNDERSTORM LOW...A FLASH FLOOD WATCH WAS NOT ISSUED FOR
TONIGHT. STILL...THE STORMS WILL HAVE SOME DECENT DOWNPOURS AND
LOCALIZED URBAN AND/OR POOR DRAINAGE FLOODING IS STILL A
POSSIBILITY.

LATER THIS EVENING...THE COVERAGE OF THE THUNDERSTORMS WILL
DIMINISH AND SKIES WILL BECOME PARTLY CLOUDY AFTER MIDNIGHT. THERE
MAY BE SOME PATCHY FOG IN AREAS THAT RECEIVED RAIN AND WHERE
CLOUDS CLEAR UP ENOUGH TO ALLOW ANY RADIATIONAL COOLING. FOG WAS
NOT INCLUDED IN THE GRIDS ATTM.

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH FRIDAY NIGHT/...
THE PATTERN WILL NOT CHANGE MUCH DURING THE SHORT TERM. THE WARM
AND HUMID AIRMASS WILL REMAIN AS WILL THE CHC FOR DAYTIME AND
EVENING SHOWERS AND TSTMS. THE SPC INDICATES THAT WE WILL BE IN A
SLIGHT RISK FOR SEVERE THUNDERSTORMS BOTH THU AND FRI. A COLD
FRONT WILL CROSS THE AREA TOWARD THE END OF THE PERIOD WITH MORE
TSTMS THEN. THE UPPER WINDS MAY DECREASE IN SPEED DURING THE SHORT
TERM...SO THE POSSIBILITY FOR SLOW MOVING THUNDERSTORMS WILL BE
GREATER. A FLASH FLOOD WATCH MAY BECOME NECESSARY...ESPECIALLY
ACROSS THE NORTHERN AREAS WHERE FFG GUIDANCE IS LOWER.

&&

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
A PREPONDERANCE OF WEAK TROUGHING ALOFT IS FORECAST BY THE GFS ALONG
THE EAST COAST THROUGH THE LONG TERM PERIOD...PERHAPS MODERATED A
BIT IN THE MIDDLE PORTION OF THE PERIOD. HPC SEEMS TO FAVOR THIS
IDEA. AT THE SURFACE...THE FRONT THAT IS FORECAST TO SETTLE SOUTH OF
OUR AREA SATURDAY LOOKS LIKE IT WILL SET UP SHOP FROM THE CENTRAL
MID ATLANTIC WESTWARD THROUGH THE TENNESSEE VALLEY. GIVEN THIS
SCENARIO...IT WAS DECIDED TO LEAVE SMALL CHANCE PROBABILITIES FOR
OUR SOUTHERN ZONES EACH DAY...WITH ONLY A SLOW SPREAD NORTHWARD INTO
OUR NORTHWESTERN ZONES BY WEDNESDAY AS A WAVE SEEMS TO APPROACH FROM
THE WEST BY THEN.

THE TROUGHING ALOFT IS THE ANTITHESIS OF YESTERDAYS SOLUTION IN
WHICH STRONG RIDGING AT UPPER LEVELS BUILT OVER OUR AREA. LACKING
THAT LATTER THEME...TEMPERATURES WERE KEPT MORE NEAR OR SLIGHTLY
ABOVE SEASONAL NORMALS.

&&

.AVIATION /20Z WEDNESDAY THROUGH MONDAY/...
A WARM FRONT HAS MOVED NORTH OF THE TAF AREA AND IT USHERED IN A
WARM MOIST AMS WHICH HAS BECOME MODERATELY UNSTABLE WITH DAYTIME HTG.
THERE ARE ALSO A COUPLE OF WEAK TROFS OF LOW PRESSURE WHICH SHOULD
PROVIDE LOW-LVL CONVERGENCE. THUS TSTMS HAVE BEGUN TO DEVELOP OVER
ERN PA AND ARE EXPECTED TO INCREASE AND MOVE EWD FOR THE REMAINDER
OF THIS AFTN. NOT SURE ATTM HOW EXTENSIVE THE TSTM COVERAGE WILL BE
SO HAVE JUST USED TEMPO GROUP IN THE TAFS WITH CBS INDICATED FROM
LATE AFTN INTO EARLY EVE.

TSTM ACTIVITY SHOULD DIMINISH BY MID TO LATE EVE...LEAVING LIGHT WINDS
AND SCT CLOUDS OVERNIGHT. SOME AREAS...ESPECIALLY THOSE THAT RECEIVE
RAINFALL...COULD SEE SOME FOG DURG THE OVERNIGHT HOURS. RDG AND MIV
WERE HIT A LITTLE HARDER WITH FCST FOG.

FOG SHOULD DISSIPATE BY MID-MORN THU BUT CONDS MAY CONT SMWHT HAZY.
WINDS WILL PICK UP OUT OF THE SW DURG THE MORNING ALSO. SCT TSTMS
ARE EXPECTED AGAIN THU AFTN AS THE BASIC WX PATTERN WILL NOT HAVE
CHANGED MUCH.

OUTLOOK...
THE CURRENT WX PATTERN IS EXPECTED TO PERSIST THROUGH FRIDAY NIGHT.
CONDS OVERALL SHOULD BE VFR BUT THERE WILL BE SOME AREAS OF MVFR OR
IFR DUE TO TSTMS AND POSSIBLY NIGHTTIME FOG/ST. A COLD FRONT IS FCST
TO MOVE THRU FRI NIGHT BRINGING MORE WIDESPREAD VFR CONDS FOR THE
WEEKEND.

&&

.MARINE...
A GENERAL TROUGHY PATTERN WILL PERSIST A THE SURFACE FOR THE NEXT
FEW DAYS WITH SLY TO SWLY FLOW CONTINUING OVER THE FCST WATERS.
WINDS AND SEAS SHOULD REMAIN BELOW SCA CRITERIA MOST OF THE TIME...
WITH THE POSSIBLE EXCEPTION OF THE PERIOD AROUND THE TIME OF A COLD
FRONT PASSAGE FRI NIGHT INTO SAT MORNING. THERE WILL ALSO BE THE
THREAT OF GENLY AFTN/EVE TSTMS OVER THE WATERS AS THE AMS REMAINS
MOIST AND UNSTABLE. BY SUNDAY WINDS ARE FCST TO SHIFT TO THE NW BUT
REMAIN RATHER LIGHT AS WEAK HIGH PRESSURE BUILDS IN BEHIND THE COLD
FRONT. WINDS ARE EXPECTED SHIFT BACK TO THE S FOR EARLY NEXT WEEK.
