AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
1057 PM EDT WED JUL 4 2012
.SYNOPSIS...
A COLD FRONT WILL SAG THROUGH THE REGION ON THURSDAY FOLLOWED BY
HIGH PRESSURE ON FRIDAY AND SATURDAY. ANOTHER COLD FRONT WILL MOVE
THROUGH LATE ON SATURDAY INTO SUNDAY MORNING AND BEGIN TO STALL TO
OUR SOUTH AND EAST. THIS WILL PROVIDE UNSETTLED, BUT SEASONAL,
CONDITIONS THROUGH TUESDAY. HIGH PRESSURE LOOKS TO RETURN ON
WEDNESDAY.
&&
.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
1045 PM PRODUCT ADJUSTMENT TO NOWCAST THE TSTMS IN THE GRIDS WITH
THE BIGGEST STORM HEADING THRU OCEAN COUNTY ATTM WITH POTENTIAL
30KT GUSTS AS WELL AS FQT LIGHTNING STRIKES.
FOR THE OVERNIGHT HOURS, WE ARE EXPECTING CLEARING FROM THE
NORTHWEST AND NORTH. A SURFACE BOUNDARY FROM NORTH IS FORECAST TO
DROP INTO OUR REGION LATE TONIGHT.
IN REGARD TO TEMPERATURES, OVERNIGHT LOWS WILL BE MAINLY IN THE 70S,
WITH SOME READINGS IN THE 60S IN THE ELEVATED TERRAIN.
THE HEAT ADVISORY FOR NORTHEASTERN MARYLAND AND CENTRAL AND
SOUTHERN DELAWARE AND THE EXCESSIVE HEAT WARNING FOR THE
PHILADELPHIA METROPOLITAN AREA WILL CONTINUE.
&&
.SHORT TERM /6 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/...
THE FRONTAL BOUNDARY WILL DROP SLOWLY THROUGH OUR SOUTHERN COUNTIES
ON THURSDAY. DEW POINT VALUES ARE FORECAST TO DECREASE GRADUALLY
INTO THE UPPER 50S AND LOWER 60S IN OUR NORTHERN AND CENTRAL
COUNTIES. THEY SHOULD REMAIN CLOSE TO 70 ON THE DELMARVA PENINSULA.
EVEN THOUGH TEMPERATURES WILL CLIMB WELL INTO THE 90S, EXCEPT IN THE
ELEVATED TERRAIN, THE HUMIDITY VALUES IN EASTERN PENNSYLVANIA AND
NEW JERSEY OUTSIDE OF THE PHILADELPHIA METROPOLITAN AREA SHOULD NOT
WARRANT THE NEED FOR ANOTHER HEAT ADVISORY.
THE EXPECTED CONDITIONS IN THE URBANIZED AREAS IN AND AROUND
PHILADELPHIA HAVE NECESSITATED THE CONTINUATION OF THE EXCESSIVE
HEAT WARNING THERE. ALSO, IN NORTHEASTERN MARYLAND AND IN CENTRAL
AND SOUTHERN DELAWARE THE HUMIDITY VALUES IN COMBINATION WITH
AFTERNOON TEMPERATURES IN THE UPPER 90S SHOULD RESULT IN HEAT INDEX
VALUES AROUND 105 AND THE NEED FOR A HEAT ADVISORY. THE HEAT
ADVISORY ON THE DELMARVA HAS BEEN EXTENDED UNTIL 800 PM ON THURSDAY.
ONE ADDITIONAL NOTE REGARDING TEMPERATURES ON THURSDAY, WITH THE OFF
SHORE WIND TRAJECTORY, IT WILL BE VERY WARM EVEN AT THE BEACH WITH
LITTLE SEA BREEZE INFLUENCE.
EVEN THOUGH THE SURFACE BOUNDARY WILL BE DROPPING THROUGH OUR REGION
ON THURSDAY, THE ATMOSPHERE WILL REMAIN CAPPED, PREVENTING THE
DEVELOPMENT OF ANY SHOWERS AND THUNDERSTORMS.
THURSDAY NIGHT...FAIR.
&&
.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
5-WAVE MODEL GUIDANCE CONTINUES TO SHOW SUBTROPICAL RIDGING FROM THE
SOUTHEAST UNITED STATES THROUGH THE UPPER MID-WEST. THIS RIDGE WILL
TRY TO SLIDE EAST BUT A LONG WAVE TROUGH DEVELOPS AND BEGINS TO FLATTEN
IT OUT...AT LEAST OVER THE EASTERN UNITED STATES BY THE END OF THE
WEEK. THE TROUGH WILL ENCOMPASS THE REGION STARTING EARLY NEXT
WEEK THROUGH THE REMAINDER OF THE LONGTERM PERIOD.
COUNTER-INTUITIVELY WE WILL ACTUALLY BE WARMING IN THE LOW-LEVELS WITH
A NORTHWEST FLOW PROVIDED BY THE MASSIVE RIDGE TO OUR WEST. EVEN
BEHIND THE DEPARTING COOL FRONT ON FRIDAY 850MB TEMPERATURES WILL
STILL BE NEAR 20C AND WE SHOULD EASILY MIX UP TO THIS LEVEL. THIS
WOULD PROVIDE A DAYTIME HIGH OF 95 TO 96 ACROSS PHILADELPHIA. THOUGH
DEWPOINTS WILL BE LOWER THAN ON THURSDAY, HEAT INDICES WILL STILL BE
IN THE UPPER 90S...THERE WILL NOT BE MUCH A BREAK.
EVEN WITH THE RIDGE OVERHEAD PROVIDING MORE OF A ZONAL FLOW, THE
IMMENSE HEAT OVER THE MID-WEST WILL HAVE AMPLE OPPORTUNITY TO ADVECT
INTO OUR REGION FOR THE START OF THE WEEKEND. DUE TO THIS, THE
EXCESSIVE HEAT WARNING HAS BEEN EXTENDED INTO LATE SATURDAY AS
SATURDAY LOOKS TO BE THE HOTTEST DAY OF THE WEEK WITH 850MB
TEMPERATURES AROUND 24C! ADD ANOTHER DEGREE OR TWO TO THE DAYTIME
HIGH DUE TO THE DOWNSLOPING FLOW AND WE COULD SEE A FEW SPOTS HIT
TRIPLE DIGITS WITH DEWPOINTS CLOSE TO 70F.
OUR SAVING GRACE, FOR THOSE WHO DO NOT LIKE THE IMMENSE HEAT AND
HUMIDITY, WOULD BE IN THE WAKE OF A SOUTHWARD MOVING COLD FRONT LATE
SATURDAY NIGHT INTO SUNDAY MORNING. AS THE FRONT NEARS LATE IN THE
AFTERNOON AND ANOTHER LEESIDE SURFACE TROUGH DEVELOPS ACROSS OUR
SOUTHERN ZONES, THE CHANCES AT SEEING CONVECTION
INCREASES..ESPECIALLY BEING THAT WE WILL BE VERY UNSTABLE AND HAVE A
TRIGGER AND FOCUS WITH THE COLD FRONT. THE FRONT WILL SLIDE TO OUR
SOUTH AND EAST BY SUNDAY MORNING BUT WITH THE UPPER LEVEL TROUGH
FORMING OVER THE EASTERN UNITED STATES AND NEARLY ZONAL FLOW IN THE
MID-LEVELS THE FRONT WILL TEND TO STALL. THIS WILL PROVIDE A PERIOD
OF UNSETTLED WEATHER FROM SUNDAY THROUGH TUESDAY AS MULTIPLE WAVES
OF ENERGY RIDE ALONG THE STALLED FRONT. IT WILL ALSO ALLOW TEMPERATURES
TO DROP TOWARDS NORMAL VALUES WITH A DECREASE IN DEWPOINTS. THE ONLY
CAVEAT TO THE DEWPOINTS WOULD BE ACROSS OUR SOUTHERN DELMARVA ZONES
WITH POSSIBLE LOW-LEVEL MOISTURE POOLING DUE TO THE PROXIMITY TO THE
BAROCLINIC ZONE.
