AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
543 PM EDT SAT JUL 23 2011

.SYNOPSIS...
A WEAK COLD FRONT OR TROUGH WILL STALL NEARBY INTO SUNDAY. A COLD
FRONT WILL APPROACH ON MONDAY AND MOVE ACROSS THE AREA MONDAY
NIGHT. IT IS EXPECTED TO STALL TO THE SOUTH AND THEN MOVE BACK
NORTH ON THURSDAY AS A WARM FRONT.

&&

.NEAR TERM /UNTIL 6 AM SUNDAY MORNING/...
TO THIS POINT...CONVECTIVE INHIBITION HAS WON OUT OVER INSTABILITY
ACROSS MOST OF THE FORECAST AREA LATE THIS AFTERNOON. THE BEST
SURFACED BASED AND MEAN LAYER INSTABILITY CONTINUES TO BE ACROSS
NORTHEAST MARYLAND AND DELAWARE...WITH LESS IN THE WAY OF INSTABILITY
FURTHER NORTH AND WEST. THIS WOULD FAVOR THESE LOCATIONS FOR CONVECTIVE
ACTIVITY LATE THIS AFTERNOON AND THIS EVENING. A WEAK SHORT WAVE
CROSSING THE EASTERN GREAT LAKES LATE THIS AFTERNOON COULD HELP
WITH SYNOPTIC SCALE ASCENT...BUT AT THIS POINT IS MY BE GETTING
TOO LATE IN THE GAME FOR MORE ORGANIZED CONVECTION OUTSIDE OF
NORTHEAST MARYLAND...DELAWARE AND THE SOUTHERN ONE-THIRD OF NEW
JERSEY.

FREEZING LEVELS ARE ABOVE 15500 FEET ACROSS THE FORECAST AREA...WITH
MINUS 20 CELSIUS LINE ABOUT 27000 FEET. THE LATTER IS IMPORTANT
BECAUSE OF THE POTENTIAL FOR ICE AND CHARGE SEPARATION...AND THE
PRODUCTION OF LIGHTING. STORMS WITH TOPS LESS THAN 27000 FEET MAY
NOT PRODUCE LIGHTNING...EVEN THOUGH WEAK UPDRAFTS ARE IN PLACE.
THE FORMER VALUE MENTIONED ABOVE IS IMPORTANT BECAUSE IT WOULD TO
TEND TO RULE OUT LARGE HAIL AS A SEVERE WEATHER TYPE OUTSIDE OF A
SUPERCELL.

THE SHEAR IS FAIRLY WEAK ACROSS THE ENTIRE AREA...SO THE THREAT
FOR MORE ORGANIZED CONVECTION MAY BE GOING BY THE BOARDS.
CONVECTION THAT DEVELOPS SHOULD BE RELATIVELY BRIEF AS MODIFIED
SOUNDINGS SUPPORT LONG THIN CAPE PROFILES. THIS IN TURN WOULD
SUPPORT WEAK UPDRAFTS. SO...RIGHT NOW IT WOULD APPEAR AS THOUGH
HEAVY RAIN MAY END UP BEING THE BEST CONVECTIVE THREAT...AS
PRECIPITABLE WATERS VALUES HOVER JUST UNDER 2 INCHES. WHILE THE
STORM MOTION IS NOT FAST (NEAR 12 KNOTS)...MOTION SHOULD BE QUICK
ENOUGH TO LIMIT THE FLASH FLOOD THREAT (OUTSIDE OF TRAINING
CELLS).

SO...THE MAIN CONVECTIVE THREAT SHOULD BE HEAVY RAIN...WITH WET
MICROBURST POTENTIAL IN THE STRONGER CELLS...WHICH ARE MORE LIKELY
ACROSS THE SOUTHERN THIRD OF THE AREA. THIS AREA HAS BEEN
HIGHLIGHTED IN THE GRIDDED FORECASTS AS THE BEST PLACE FOR THUNDER
INTO THE EVENING HOURS.

OTHERWISE...THE DEW POINTS WERE 5 TO 10 DEGREES LOWER ON THE WEST TO
NORTHWEST WIND THIS AFTERNOON, BUT THEY APPARENTLY HAD BOTTOMED
OUT AND LIKELY WILL RISE SOME AGAIN OVERNIGHT. STILL, THAT HAD
ALLOWED US TO DROP THE HEAT WARNING FOR OUR THREE NORTHWESTERNMOST
COUNTIES. GIVEN OUR FORECAST FOR TOMORROW, IT SHOULD ALSO ALLOW
THE WARNING TO EXPIRE ON TIME THIS EVENING OVER ALL BUT THE
URBANIZED AREAS OF THE DELAWARE VALLEY. ON THE OTHER HAND, THE
ANTICIPATED RISE IN DEW POINTS KEEPS US IN THE CONTINUITY/HIGHER
GUIDANCE RANGE REGARDING THE MINS.

A TROUGH WAS DRAPED ACROSS THE AREA NEAR THE INTERSTATE 95
CORRIDOR, AND IT ISN'T PROGGED TO MAKE MUCH PROGRESS TO THE SOUTH.
A MID LEVEL IMPULSE WAS APPROACHING FROM THE WEST-NORTHWEST, BUT
THE LOWER DEW POINTS HAD GIVEN MORE VALUE TO THE VERY WARM
TEMPERATURES ALOFT IN TERMS OF CONVECTIVE INHIBITION. WE'RE
KEEPING THE FORECAST SIMPLE AND GOING WITH SLIGHT CHANCE TO CHANCE
POPS THAT INCREASE AS ONE MOVES INTO AND SOUTHEAST OF THE SURFACE
TROUGH AND THE BETTER LOW LEVEL CONVERGENCE.

&&

.SHORT TERM /6 AM SUNDAY MORNING THROUGH TUESDAY/...
THE MAIN FOCUS FOR CONVECTION IN OUR OPINION IS MONDAY INTO MONDAY
NIGHT WITH THE PASSAGE OF A TRUE COLD FRONT. UNTIL THEN, WE AREN'T
TRYING TO FOCUS ON IMPULSES GRADUALLY BREAKING APART THE RIDGE
WITH THIS PACKAGE. WE ARE CONFINING THE POPS TO THE LOWER CHANCE
RANGE THROUGH SUNDAY NIGHT, THEN GOING UP INTO THE HIGH CHANCE TO
LIKELY RANGE AHEAD OF THE FRONT. THERE IS PRETTY GOOD AGREEMENT
THAT THE FRONT CLEARS THE AREA BY DAYBREAK TUESDAY, AND WE'RE
KEEPING TUESDAY DRY.

REGARDING TEMPERATURES, THE H925 INDICATIONS FROM THE ECMWF AND
GFS ARE THAT SUNDAY SHOULD BE LESS HOT THAN IT HAS BEEN IN A
COUPLE OF DAYS. IT IS AN OPEN QUESTION WHETHER WE STILL NEED THE
HEAT WARNING OVER THE URBANIZED SECTIONS OF DELAWARE VALLEY, BUT
WE WOULD RATHER NOT DROP IT UNTIL WE ARE SEEING CONSISTENT
INDICATIONS THAT WE WILL FALL SHORT. FROM SUNDAY NIGHT THROUGH
MONDAY NIGHT, WE ARE ON THE FAVORED WARMER GUIDANCE/CONTINUITY
TRACK, AND FOR TUESDAY WE ACTUALLY RESIDE BETWEEN THE WARMER AND
COOLER GUIDANCE.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
THE CLOSING PART OF JULY WILL HAVE MUCH IN COMMON WITH THE MONTH AS
A WHOLE. MORE HEAT AND HUMIDITY WILL BE ARRIVING ACROSS OUR PART OF
THE COUNTRY DURING THE MIDDLE OF NEXT WEEK AND AGAIN IT MAY STAY
UNTIL THE END OF THE MONTH.

THE UPPER RIDGE OF HIGH PRESSURE TO THE SOUTH (WHICH HAS RELAXED
DURING THE SHORTER RANGE OF THE FCST) WILL AGAIN BE BUILDING ACROSS
THE EASTERN PART OF THE COUNTRY BEHIND A DEPARTING H5 TROUGH. THE
STORM TRACK BY THE END OF THE WEEK WILL SET UP ALONG THE U.S./CANADA
LINE. MUCH OF THE PERIOD WILL BE DRY...BUT THERE WILL BE SOME
AFTERNOON AND EVENING CHC FOR SHOWERS/TSTMS THU-SAT...BUT NO LARGE
ORGANIZED SYSTEM IS FORESEEN.

HIGH TEMPERATURES ON WEDNESDAY WILL FEATURE PLENTY OF UPPER 80S
ACROSS THE NRN AREAS AND LOW 90S OVER THE METRO AREAS AND THE
DELMARVA. HIGHS WILL INCREASE BY ABOUT 5 DEGREES FROM WED THRU FRI
WHICH WILL PROBABLY BE THE WARMEST DAY OF THE PERIOD. LOWS WILL
MOSTLY BE IN THE 70S...BUT SOME MID TO UPPER 60S WILL BE ACROSS THE
NRN AREAS WED AND THU MORNINGS.

&&

.AVIATION /22Z SATURDAY THROUGH THURSDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY AND SURROUNDING AREAS.

WITH A WEAK EAST COAST TROUGH PROVIDING A W TO NW FLOW OF SLIGHTLY
DRIER AIR, SHOWER/TSTMS ARE HAVING A TOUGH TIME FORMING TODAY.
SCT TO BKN MID AND HIGH CLOUDS PREVAIL WITH ONLY A FEW CU IN SOME
LOCATIONS. THE SEA BREEZE WILL BE WEAK AND UNABLE TO MOVE VERY FAR
INLAND. A WEAK BACKDOOR FRONT IS FORECAST TO SLIP SOUTH INTO THE
AREA TONIGHT. GUIDANCE CONTINUES TO SHOW THE POSSIBILITY FOR
SHOWERS/TSTMS BUT THESE SHOULD BE FEW AND FAR BETWEEN, AND WILL
NOT BE INCLUDED IN THE TAFS. WITH MID/HIGH CLOUDS AND LIGHT WINDS,
COULD SEE A FEW MVFR VSBYS IN FOG/HAZE LATE TONIGHT, ESPECIALLY IN
SOUTHERN AREAS. AS THE FRONTAL ZONE DROPS SOUTH, WINDS WILL
BECOME NW TO N 5 TO 10 KT LATE TONIGHT INTO SUNDAY. THE PRESSURE
GRADIENT WILL WEAKEN DURING THE DAY SUNDAY ALLOWING WINDS TO BECOME
MORE WESTERLY. THIS WILL ALSO ALLOW FOR A STRONGER SEA BREEZE.
THE THREAT FOR SHOWERS AND TSTMS WILL BE SLIGHTLY HIGHER THAN
TODAY, ESPECIALLY IN THE AFTERNOON AND EVENING, BUT MAY STILL NOT
WARRANT INCLUSION IN THE TAFS AT THIS TIME. VFR CONDITIONS WILL ONCE
AGAIN PREVAIL.

OUTLOOK...
A COLD FRONT IS FORECAST TO CROSS OUR REGION LATE MONDAY INTO
MONDAY NIGHT. SHOWERS AND TSTMS WILL LIKELY PRECEDE AND ACCOMPANY
THE FRONTAL PASSAGE. HIGH PRESSURE WILL THEN MOVE IN WITH A NEW
AIR MASS TUESDAY AND DOMINATE OUR WEATHER, AT LEAST, THROUGH
THURSDAY WITH VFR FLYING CONDITIONS.

&&

.MARINE...
FAVORABLE BOATING CONDITIONS ARE FORECAST TO CONTINUE THROUGH MUCH
OF THE UPCOMING WEEK WITH WINDS AND SEAS REMAINING BELOW SMALL CRAFT
ADVISORY CRITERIA. A WEAK BACKDOOR FRONT WILL APPROACH THE REGION
FROM THE NORTH TONIGHT AND MOVE SOUTH INTO OR THROUGH THE AREA LATE
TONIGHT AND SUNDAY. A STRONGER FRONT IS EXPECTED TO ARRIVE FROM THE
NORTHWEST MONDAY NIGHT. HIGH PRESSURE WILL FOLLOW TUESDAY AND
DOMINATE OUR WEATHER PATTERN INTO, AT LEAST, THURSDAY. WHILE AN
ISOLATED SHOWER OR TSTM IS POSSIBLE JUST ABOUT ANY TIME TONIGHT
INTO MONDAY, THE BEST CHANCE FOR SHOWERS/TSTMS WILL BE AHEAD OF
AND WITH THE FRONT LATE MONDAY AND MONDAY NIGHT.
