AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
1201 PM EDT SUN AUG 9 2009

.SYNOPSIS...
A WARM FRONT EXTENDED FROM THE GREAT LAKES TO THE MIDDLE ATLANTIC
COAST DURING THE NIGHT.  THE FRONT WILL LIFT NORTHWARD ACROSS OUR
REGION TODAY.  A HOT HUMID AIRMASS WILL BUILD UP FROM THE SOUTHWEST
FOR MONDAY INTO TUESDAY.  A FRONTAL BOUNDARY FROM THE NORTHWEST IS
FORECAST TO PASS THROUGH OUR REGION LATE ON TUESDAY.  THE BOUNDARY
IS EXPECTED TO STALL ACROSS SOUTHERN VIRGINIA AND NORTH CAROLINA FOR
THE MIDDLE AND LATE PARTS OF THE NEW WEEK AS HIGH PRESSURE FROM THE
WEST BUILDS ACROSS THE NORTHEASTERN STATES.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
SCATTERED SHOWERS AND TSTMS CONTINUE TO DEVELOP IN CENTRAL PA
ALONG THE WARM FRONT. SINCE THE GROUND ALREADY IS WET IN MANY
AREAS, AND THE FACT THAT THE CONVECTION CONTINUES TO BE HIGHLY
EFFICIENT FOR DEVELOPING TORRENTIAL DOWNPOURS, WE HAVE ISSUED A
FLASH FLOOD WATCH INTO LATE TONIGHT.

OTHERWISE...THE FIRST BATCH OF SHOWERS IS PRESENTLY MOVING OFF
THE SRN NJ SHORE. THE RADAR ECHOS MOVING AWAY HAVE A SUBTLE TWIST
IN THEM...INDICATING THE MID-LEVEL VORT MAX WITH THE SYSTEM.
TORRENTIAL DOWNPOURS OCCURRED AS THIS AREA MOVED BY METRO
PHILADELPHIA AND PRODUCED SOME URBAN AND SMALL STREAM FLOODING
AROUND THE CITY. RAINFALL TOTALS OF 1 TO 2 INCHES PER HOUR WERE
OBSERVED WITH ACTIVITY. ANOTHER WEAKENING BATCH OF SHOWERS WILL
MOVE ACROSS SE PA AND SRN NJ (SOUTH OF WHERE THE PREVIOUS RAINS
FELL). LOOKS LIKE THE ACTIVITY FOR THE AFTERNOON WILL BE
SCATTERED, SO A 40 POP WAS USED FOR THE UPDATE. ANY RAINS THIS
AFTERNOON WILL BE OF THE DOWNPOUR VARIETY WITH THE TROPICAL AIR
MASS ARRIVING ON THE SCENE. A WARM FRONT MOVING ACROSS THE AREA
COULD FOCUS ANY ACTIVITY ALONG IT.

TEMPERATURES, DEW POINTS AND WINDS WERE ADJUSTED TO ACCOUNT FOR
THE FRONTAL MOVEMENT AND LOCAL EFFECTS. MAX TEMPS WERE LOWERED UP
NORTH WHERE CLOUDS SHOULD RULE MUCH OF THE DAY. ALL GRIDS AND
PUBLIC PRODUCTS HAVE ALREADY BEEN SENT.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH TUESDAY/...
AFTER A MUGGY NIGHT TONIGHT, THE UPPER LEVEL RIDGE SHOULD MAKE ITS
FARTHEST PUSH OVER OUR REGION ON MONDAY MORNING BEFORE IT BEGINS TO
GET KNOCKED BACK TO THE SOUTH.  THE LOW LEVEL FLOW SHOULD PULL SOME
OF THE 90 DEGREE PLUS AIR FROM THE MIDDLE MISSISSIPPI RIVER VALLEY
INTO OUR REGION FOR MONDAY.  TEMPERATURES AT 850 HPA SHOULD BE NEAR
+20C OVER OUR CENTRAL AND SOUTHERN COUNTIES.  WE WILL CONTINUE TO
FORECAST TEMPERATURES IN THE 90S FOR ALMOST OUR ENTIRE REGION.

WITH DEW POINT TEMPERATURES EXPECTED TO BE AROUND 70 ON MONDAY
AFTERNOON, HEAT INDEX VALUES SHOULD RISE INTO THE 100 TO 105 RANGE
IN THE PHILADELPHIA METROPOLITAN AREA.  AS A RESULT, WE WILL
MAINTAIN THE EXCESSIVE HEAT WATCH FOR OUR HIGHLY URBANIZED AREAS.
WE MAY EVENTUALLY NEED AN ADVISORY FOR OTHER LOCATIONS, AS HEAT
INDEX VALUES SHOULD BE NEAR 100 TO THE NORTH OF THE WATCH, AND
AROUND 105 TO THE SOUTH.

THE HIGHEST INSTABILITY VALUES IN OUR REGION DURING THE SHORT TERM
PERIOD ARE EXPECTED ACROSS OUR NORTHERN COUNTIES FROM MONDAY
AFTERNOON INTO MONDAY EVENING.  THE STORM PREDICTION CENTER HAS
PLACED THAT AREA UNDER ITS SLIGHT RISK DESIGNATION FOR SEVERE
WEATHER AT THAT TIME.

AS THE UPPER LEVEL RIDGE RETREATS, IT CONTINUES TO APPEAR AS THOUGH
TUESDAY WILL NOT BE AS HOT AS MONDAY.  TEMPERATURES AT 850 HPA OVER
PHILADELPHIA ARE FORECAST TO BE AROUND +17C ON TUESDAY AFTERNOON.
NEVERTHELESS, THAT WOULD STILL TRANSLATE TO A MAXIMUM TEMPERATURE IN
THE LOWER 90S, AND HEAT INDEX VALUES MAY APPROACH 100.

A FRONTAL BOUNDARY IS FORECAST TO DROP DOWN FROM THE NORTHWEST ON
TUESDAY AFTERNOON, AND IT MAY BRING ADDITIONAL SHOWERS AND
THUNDERSTORMS.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
DURING THE PERIOD FROM WEDNESDAY THROUGH SATURDAY, THE UPPER PATTERN
IS EXPECTED TO SHIFT GRADUALLY FROM A WEAK TROUGH OVER THE NORTHEAST
TO A RIDGE ATTEMPTING TO BUILD OVER THE REGION.

A SURFACE BOUNDARY IS FORECAST TO PASS THROUGH OUR REGION FROM LATE
TUESDAY INTO TUESDAY NIGHT.  IT SHOULD STALL TO OUR SOUTH DURING THE
PERIOD, WITH HIGH PRESSURE FROM THE WEST BUILDING ACROSS NEW YORK
AND NEW ENGLAND.  WE ARE EXPECTING MAINLY DRY WEATHER.  HOWEVER, WE
HAVE INCLUDED CHANCE POPS FOR OUR SOUTHERN COUNTIES FOR LATE IN THE
WEEK.  A WEAK SURFACE WAVE MAY DEVELOP AND MOVE ALONG THE STALLED
SURFACE BOUNDARY.

&&

.AVIATION /16Z SUNDAY THROUGH THURSDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY AND SURROUNDING AREAS.

THE FIRST BATCH OF SHOWERS PULLING AWAY...AND THE ACTIVITY
EXPECTED FOR THE AFTERNOON SHOULD BE MORE OF THE SCATTERED
VARIETY. FREQUENT AMDS ARE EXPECTED WITH THE CONDITIONS EXPECTED
TO RANGE FROM MVFR TO IFR AT TIMES. HAZE SHOULD BE A FACTOR AS THE
WARM FRONT AND TROPICAL AIR ARRIVE LATER TODAY. WINDS GENERALLY S
TO SE AHEAD OF THE WARM FRONT AND SW BEHIND IT. WIND SPEEDS SHOULD
BE 10 KNOTS OR LESS...OUT SIDE OF ANY CONVECTION.

OUTLOOK...
HAZY, HOT AND HUMID WEATHER IS ON TAP FOR MONDAY WITH SCATTERED
AFTERNOON AND EVENING TSTMS POSSIBLE, MAINLY IN OUR NORTHERN AND
WESTERN SECTIONS. AN APPROACHING COLD FRONT IS EXPECTED TO CROSS
THE AREA LATE TUESDAY INTO TUESDAY NIGHT WITH YET ANOTHER ROUND
OF CONVECTION. HIGH PRESSURE WILL BRING A RETURN TO FAIR VFR
WEATHER FOR WEDNESDAY.

&&

.MARINE...
QUIET CONDITIONS ARE FORECAST FOR THE COASTAL WATERS THROUGH MUCH OF
THE UPCOMING WEEK. A SUMMERTIME PATTERN WITH HIGH PRESSURE ANCHORED
OFF TO THE EAST WILL BRING A SOUTH TO SOUTHWEST FLOW OF MUCH WARMER
AIR INTO THE REGION. SHOWERS AND POSSIBLY AN ISOLATED TSTM OR TWO
WILL AFFECT THE AREA THIS MORNING, BUT SHOULD BE ENDING BY MIDDAY.
WHATEVER AFTERNOON AND EVENING TSTMS THAT DO FORM TODAY AND MONDAY
SHOULD REMAIN WELL TO OUR NORTH AND WEST. MORE WIDESPREAD SHOWER AND
TSTM ACTIVITY COULD PRECEDE AND ACCOMPANY A COLD FRONT TUESDAY INTO
TUESDAY NIGHT. HIGH PRESSURE WILL THEN RETURN FOR WEDNESDAY.
