AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
400 PM EDT TUE JUL 4 2006

.SHORT TERM /TONIGHT THROUGH FRIDAY/...
AT 4:00 PM, A LINE OF CONVECTION EXTENDED FROM AROUND MORRISTOWN TO
TRENTON TO PHILADELPHIA TO NEAR MIDDLETOWN, DELAWARE.  THE NEW
JERSEY PORTION OF THE LINE SHOULD REACH THE COAST SHORTLY AFTER 5:00
PM.  THE LOWER PART OF THE LINE WILL TAKE A LITTLE LONGER TO MAKE
ITS WAY THROUGH NORTHEASTERN MARYLAND AND DELAWARE, BEING THAT THE
ACTIVITY CONTINUED BACK INTO THE BALTIMORE AREA.

SEVERE TSTM WATCH 582 REMAINS IN EFFECT UNTIL 9:00 PM FOR OUR ENTIRE
FORECAST AREA.  A NUMBER OF WARNINGS HAVE ALREADY BEEN ISSUED.

THE TSTM ACTIVITY SHOULD LESSEN AFTER DARK.  HOWEVER, WEVE KEPT A
CHANCE OF SHOWERS AND TSTMS DURING THE OVERNIGHT FOR MOST OF OUR
REGION JUST IN CASE SOME OF THE ACTIVITY OVER THE EASTERN OHIO RIVER
VALLEY AND EASTERN LAKES THIS AFTERNOON HOLDS TOGETHER AS IT MOVES
EASTWARD.

THE COLD FRONT EXTENDED FROM NIAGARA FALLS TO FORT WAYNE AT 4:00
PM.  THE FRONT WILL CONTINUE TO SINK TO THE SOUTH AND IT SHOULD
REACH OUR REGION BY MORNING.  THE FRONT WILL STALL AND SHOWERS AND
TSTMS WILL REDEVELOP ALONG IT ON WEDNESDAY.  WITH THE FRONT
REMAINING NEARLY STATIONARY THROUGH THE DAY AND WITH PRECIPITABLE
WATER VALUES IN THE 2.00 TO 2.25 INCH RANGE SOME LOCATIONS COULD
PICK UP A FAIR AMOUNT OF RAIN AT THAT TIME, ESPECIALLY FROM THE PHL
METROPOLITAN AREA SOUTHWARD.

THE FRONT IS ANTICIPATED TO BEGIN MOVING TO THE SOUTH AGAIN ON
WEDNESDAY NIGHT AS THE MID/UPPER LEVEL TROUGH DIGS DOWN FROM THE
NORTH.  EASTERN PENNSYLVANIA AND NORTHERN AND CENTRAL NEW JERSEY
SHOULD BEGIN TO EXPERIENCE SOME CLEARING AT THAT TIME.

A CHANCE OF SHOWERS WILL LINGER INTO THURSDAY MORNING ON PARTS OF
THE DELMARVA AND IN EXTREME SOUTHERN NEW JERSEY BEFORE THE SUN
BEGINS TO BREAK OUT DURING THE AFTERNOON.

HIGH PRESSURE WILL CONTINUE TO BUILD DOWN INTO OUR REGION DURING
THURSDAY NIGHT AND FRIDAY, WITH NOTICEABLY LOWER HUMIDITY LEVELS.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
HIGH PRESSURE IS FORECAST TO REMAIN IN CONTROL FROM FRIDAY NIGHT
INTO MONDAY.  AS THE CENTER OF THE HIGH PASSES OFF THE COAST WELL
GET INTO A WARM RETURN FLOW AND TEMPS WILL BEGIN TO NEAR 90 DEGREES
AGAIN BY SUNDAY AND MONDAY IN SOME OF OUR CENTRAL AND SOUTHERN
COUNTIES.  A COLD FRONT IS EXPECTED TO DROP DOWN FROM THE NORTH
EARLY IN THE NEW WEEK.  FOR THE TIME BEING, WEVE SIMPLY INSERTED
SOME SLIGHT CHANCE POPS FOR MONDAY AND TUESDAY FOR PARTS OF EASTERN
PENNSYLVANIA AND NORTHERN AND CENTRAL NEW JERSEY.

&&

.AVIATION...
STRONG AFTERNOON AND EVENING CONVECTION MOVING INTO CENTRAL AND
EASTERN PARTS OF OUR AREA SHOULD DIMINISH AS DIURNAL EFFECTS WANE
THIS EVENING.  ABE AND RDG WERE AMENDED TO REMOVE THE STRONG
THUNDERSTORM MENTION, AS ANY ACTIVITY BEHIND THE INITIAL SQUALL LINE
SHOULD BE GOVERNED BY LESS UNSTABLE CONDITIONS.  AS THE CONVECTION
DECREASES, DEBRIS CLOUDS AND MARGINAL VFR VISIBILITIES SHOULD ENSUE
FOR THE OVERNIGHT PERIOD.  THEN, SCATTERED SHOWERS AND POSSIBLE
THUNDERSTORMS WERE ALLUDED TO WITH A VICINITY REMARK STARTING
WEDNESDAY MORNING WITH THE PROXIMITY OF THE FRONT.  OTHERWISE,
STRATOCUMULUS CLOUDS ARE EXPECTED WEDNESDAY.

&&

.MARINE...
CONDITIONS ARE FORECAST TO REMAIN BELOW SMALL CRAFT ADVISORY
CRITERIA, EVEN THOUGH WAVE HEIGHTS WILL GET CLOSE, ESPECIALLY
TONIGHT.  WAVEWATCH STILL HAS A BRIEF PERIOD OF 5 FOOT SEAS TONIGHT,
BUT WE WILL CAP IT AT 4 FEET.  AS WINDS TURN TO A NORTHERLY
COMPONENT THURSDAY AND CONTINUE FRIDAY AND INTO SATURDAY, SEAS
SHOULD CONTINUE AT 3 OR 4 FT ON THE OCEAN.  THEN, SEAS SHOULD RELAX
A BIT AS HIGH PRESSURE BUILDS OVER THE REGION FOR THE WEEKEND.
