AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
745 PM EDT WED JUN 27 2007
.SYNOPSIS...
A SOUTHWEST FLOW AROUND HIGH PRESSURE IN THE WESTERN ATLANTIC
HAS COMBINED WITH A RIDGE OF HIGH PRESSURE IN THE UPPER ATMOSPHERE
TO BRING HOT AND HUMID CONDITIONS TO THE REGION TODAY. THE HIGH
WILL MOVE SLOWLY OFF TO THE SOUTH AND EAST AS A COLD FRONT
APPROACHES THURSDAY. THE FRONT WILL CROSS THE REGION LATE THURSDAY
INTO FRIDAY. TEMPERATURES AND HUMIDITIES WILL GRADUALLY LOWER
THEREAFTER. HIGH PRESSURE WILL BUILD IN FOR THE WEEKEND AND
CONTINUE TO INFLUENCE OUR WEATHER THROUGH THE EARLY PART OF NEXT
WEEK.
&&
.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
THE EXCESSIVE HEAT WARNING FOR THE HIGHLY URBANIZED AREAS FOR
TODAY WAS ALLOWED TO EXPIRE AT 7 PM. A SEVERE THUNDERSTORM WATCH
IS IN EFFECT FOR PORTIONS OF NORTHERN NJ AND ALL OF OUR PA
COUNTIES UNTIL 11 PM DUE TO LINGERING STORMS, ESPECIALLY ACROSS
NORTHERN PORTIONS OF THE REGION. TODAYS HEAT HAS TOUCHED OFF SCATTERED
THUNDERSTORMS, ESPECIALLY IN OUR NORTHERN AND WESTERN AREAS. THE
SEVERE THUNDERSTORM WATCH FOR THE LEHIGH VALLEY AND POCONOS IN PA
AND FOR NORTHERN NJ WILL REMAIN IN EFFECT UNTIL 8 PM OR UNTIL THE
THREAT OF SEVERE WEATHER HAS ENDED. THE CONVECTIVE ACTIVITY WILL
TAPER OFF AFTER SUNSET, ALTHOUGH WELL KEEP A MIN CHANCE OF A
SHOWER/TSTM THROUGHOUT THE NIGHT.
&&
.SHORT TERM /6 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/...
THE EXCESSIVE HEAT WARNING CONTINUES FOR THE HIGHLY URBANIZED ZONES
IN AND AROUND PHILADELPHIA UNTIL 7:00 PM THIS EVENING WITH HEAT
INDEX VALUES CURRENTLY RUNNING AROUND 100. ITLL BE DIFFICULT FOR
URBAN AREAS TO COOL OFF MUCH TONIGHT AND IT NOW APPEARS THAT
TEMPERATURES THURSDAY WILL GET INTO THE LOW 90S ONCE AGAIN. IF
THIS DOES OCCUR, IT WILL BE OUR FIRST HEAT WAVE OF THE SEASON.
SINCE THE FRONT WILL NOT CROSS THE AREA UNTIL THURSDAY NIGHT AND
THE SAME AIRMASS THAT WERE IN TODAY WILL STILL BE WITH US TOMORROW,
WE WILL REISSUE THE EXCESSIVE HEAT WARNING FOR YET ANOTHER DAY.
IT WILL BE IN EFFECT FROM NOON TO 7 PM THURSDAY. THERE IS THE
POSSIBILITY THAT CLOUDS AND SHOWERS/TSTMS ASSOCIATED WITH THE
APPROACHING FRONT MAY GET INTO THE AREA BEFORE 7 PM AND THIS
MAY BRING THE WARNING TO AN ABRUPT HALT.
WITH THE EXPECTED HEATING THURSDAY AND THE ADDED LIFT AHEAD OF
THE COLD FRONT, SHOWERS AND THUNDERSTORMS ARE EXPECTED TO BE
MORE WIDESPREAD THAN TODAY. THE STORM PREDICTION CENTER HAS PUT
OUR ENTIRE FORECAST AREA IN A SLIGHT RISK OF SEVERE WEATHER FOR
LATER THURSDAY INTO THURSDAY NIGHT.
THE FRONT WILL DROP SLOWLY ACROSS OUR AREA LATE THURSDAY AND THURSDAY
NIGHT. SHOWERS AND TSTMS WILL END FROM NW TO SE LATE THURSDAY
NIGHT INTO FRIDAY, BUT MAY LINGER OVER OUR EXTREME SOUTHERN
AREAS INTO FRIDAY NIGHT.
&&
.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
HIGH PRESSURE PUSHING DOWN FROM THE NORTHWEST WILL INFLUENCE OUR
WEATHER THROUGH THE PERIOD. IT WILL BE GENERALLY FAIR AND DRY
OVER THE WEEKEND AND INTO THE EARLY PART OF NEXT WEEK WITH
NEAR SEASONABLE TEMPERATURES. WARMER AND MORE HUMID AIR WILL
MOVE BACK IN WEDNESDAY ALONG WITH THE THREAT OF SHOWERS AND
THUNDERSTORMS.
&&
.AVIATION /00Z THURSDAY THROUGH MONDAY/...
IN KEEPING WITH THE NATURE OF THE CONVECTIVE ACTIVITY, WE HAVE VCTS
IN THE TWO NWRN SITES, CBS MENTIONED IN THE DEL VALLEY SITES, AND
ONLY SCT CU IN THE SERN SITES. WE END THEM DURING THE EVENING, AND
THEN GO WITH A PERSISTENCE FORECAST REGARDING OVERNIGHT VSBYS IN
HAZE AND FOG. THE ONLY SITE THAT WE BRING TO IFR VSBY IS MIV, AND
THAT IS FOR LATE TONIGHT.
WE EXPECT CU TO BEGIN TO DEVELOP BY MID MORNING TOMORROW, AND WE
EXPECT VSBYS TO IMPROVE TO THE VFR CATEGORY BY THAT TIME. TSTMS WITH
THE FRONT ARE NOT FORECAST PRIOR TO 18Z.
A COLD FRONT WILL BE PUSHED SOUTH BY ADVANCING HIGH PRESSURE
BUILDING SOUTH FROM THE GREAT LAKES IN TIME FOR THE WEEKEND. IT
SHOULD BE, AT LEAST, PRECEDED BY MORE ORGANIZED CONVECTIVE ACTIVITY.
&&
.MARINE...
WE ARE COUNTING ON THE MARINE LAYER TO KEEP WINDS AND SEAS BELOW SCA
CRITERIA THROUGH THE REST OF THE BERMUDA HIGH REGIME. WE HAVE THE
LEAST AMOUNT OF CONFIDENCE IN THAT TONIGHT, WHEN AIR TEMPERATURES
WILL APPROACH WATER TEMPERATURES, THE MARINE LAYER WILL WEAKEN SOME,
AND THE GRADIENT WILL BE MODERATE.
ANY TSTMS THAT WANDER OVER THE WATERS IN THE PRE-FRONTAL
ENVIRONMENT, LACKING ANY LARGE SCALE FORCING, SHOULD WEAKEN FAIRLY
RAPIDLY OVER THE COOLER WATER. THAT LIKELY WILL NOT BE THE CASE WHEN
THE FRONT APPROACHES BEGINNING TOMORROW LATE AFTERNOON AND EVENING.
A STRONG COLD FRONT IS FORECAST TO DROP ACROSS THE REGION THURSDAY
NIGHT. THE WIND DIRECTION IS EXPECTED TO BECOME NORTHERLY FOR FRIDAY
INTO SATURDAY. A REINFORCING SHOT OF COOL AIR WILL DROP ACROSS THE
AREA SATURDAY NIGHT. THIS WILL CAUSE WINDS TO BECOME VARIABLE LATE
SATURDAY INTO SATURDAY NIGHT AND THEN SWING BACK AROUND TO THE
NORTH FOR SUNDAY.
