AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
340 PM EDT WED JUL 21 2010

.SYNOPSIS...
A WEAK FRONTAL TROUGH WILL CROSS THE AREA THIS EVENING AND MOVE OFF
TO THE SOUTH AND EAST LATER TONIGHT INTO THURSDAY. HIGH PRESSURE AND
SOMEWHAT DRIER AIR WILL BUILD INTO OUR AREA THURSDAY. A WARM FRONT
IS EXPECTED TO CROSS THE AREA FRIDAY AND BRING HOT AND HUMID WEATHER
FOR MUCH OF THE WEEKEND. A STRONG COLD FRONT IS FORECAST TO CROSS
THE AREA LATE SATURDAY NIGHT OR SUNDAY. HIGH PRESSURE WILL THEN BUILD
INTO THE AREA WITH A FRESH BATCH OF SLIGHTLY COOLER AND DRIER AIR FOR
THE EARLY PART OF NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
HOT AND HUMID CONDITIONS PREVAIL AROUND THE AREA THIS AFTERNOON.
HEAT INDICES ARE WELL INTO THE 90S IN MANY SECTIONS. WITH A VERY
UNSTABLE ATMOSPHERE, THE STORM PREDICTION CENTER HAS PLACED ALL
BUT OUR SOUTHERN SECTIONS IN A SEVERE THUNDERSTORM WATCH UNTIL
9 PM. IT NOW APPEARS THAT OUR NORTHERN SECTIONS WILL HAVE THE
MOST TSTM ACTIVITY DURING THE LATE AFTERNOON AND EVENING HOURS.
FARTHER SOUTH, SCATTERED CONVECTION IS EXPECTED. ANY STORMS THAT
FORM IN THE WATCH AREA COULD BE ACCOMPANIED BY DAMAGING WINDS AND
HAIL. THE ACTIVITY WILL TAPER OFF AND END BY OR SHORTLY AFTER
MIDNIGHT. THAT WILL LEAVE US WITH CLEARING SKIES. LOW TEMPERATURES
TONIGHT IN THE 60S TO LOWER 70S.

&&

.SHORT TERM /6 AM THURSDAY THROUGH SATURDAY/...
HIGH PRESSURE WILL BRING US A SLIGHTLY DRIER AND MORE STABLE
AIRMASS THURSDAY. IT WILL BE THE ONLY DAY THIS WEEK WHEN THERE
WILL BE NO MENTION OF PRECIPITATION. UNFORTUNATELY, THE AIRMASS
WILL NOT BRING COOLER TEMPERATURES TO THE REGION. HIGHS WILL BE
IN THE 80S TO LOWER 90S. WITH THE HIGH PARKED OVER US THURSDAY
NIGHT, SKIES WILL BE MOSTLY CLEAR. OVERNIGHT LOWS WILL BE IN THE
60S TO LOWER 70S. A WARM FRONT WILL CROSS THE AREA FRIDAY INTO
FRIDAY NIGHT. THIS WILL BRING BACK THE THREAT FOR SHOWERS AND
THUNDERSTORMS. TEMPERATURES WILL BEGIN TO INCH UP ON FRIDAY WITH
HIGHS IN THE 80S NORTH TO THE LOWER AND MID 90S SOUTH. TEMPERATURES
FRIDAY NIGHT WILL HAVE A DIFFICULT TIME DROPPING, WITH READINGS
IN THE UPPER 60S AND 70S. SATURDAY WILL BE A BRUTALLY HOT AND HUMID
DAY WITH HIGHS AROUND 90 NORTH AND IN THE MID TO UPPER 90S SOUTH.
HEAT INDICES WILL RANGE FROM THE MID 90S NORTH TO NEAR 110 IN
OUR SOUTHERN AND URBAN AREAS. HEAT ADVISORIES/WARNINGS ARE LIKELY,
IF THESE READINGS DO ACTUALLY OCCUR. SINCE IT IS THE THIRD DAY OF
OUR FORECAST PERIOD, NO HEADLINES WILL BE ISSUED AT THIS TIME.
IT WILL CONTINUE TO BE COVERED IN THE HWO AS AN OUTLOOK.

&&

.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
THE GENERAL CONSENSUS FOR THIS TIME FRAME IS FOR A LARGE UPPER-LEVEL
RIDGE ACROSS THE SOUTHERN STATES TO THE CENTRAL ROCKIES. SOME
UPPER-LEVEL TROUGHING THEN IS MAINTAINED FROM THE MIDWEST TO THE
NORTHEAST. AS THE UPPER-LEVEL FLOW BUCKLES SOME DURING THE COURSE OF
THIS TIME FRAME, THE UPPER-LEVEL TROUGH MAY TEND TO AMPLIFY ACROSS
THE NORTHEAST AS THE RIDGE ACROSS THE SOUTH EXPANDS TOWARD THE HIGH
PLAINS. THERE ARE SOME UNCERTAINTIES INVOLVED ESPECIALLY WITH THE
DETAILS THIS FAR OUT IN TIME, AND THIS IS MOSTLY TIED TO THE TIMING
OF THE SHORT WAVE ENERGY AND ASSOCIATED SURFACE LOWS AND FRONTS.
TAKING INTO AN ACCOUNT THE OUTLIER SOLUTIONS REGARDING A QUICKER
TIMING OF THE FRONTS, HPC WENT WITH A BLEND OF THE CANADIAN AND GFS
PARALLEL TO START, THEN SWITCHED TO A BLEND OF THE GFS PARALLEL AND
ECMWF ENSEMBLE MEAN MONDAY NIGHT ONWARD. WE GENERALLY FOLLOWED HPC
GUIDANCE, ALTHOUGH DID SOME BLENDING OF CONTINUITY SATURDAY NIGHT
AND SUNDAY GIVEN THE TIMING UNCERTAINTY OF THE COLD FRONT.

BASED ON THE ABOVE, A RATHER HOT AIRMASS IS EXPECTED TO BE IN PLACE
SATURDAY NIGHT INTO SUNDAY. THIS WILL PROBABLY ALLOW FOR SOME SORT
OF A LEE SIDE TROUGH IN THE VICINITY SOUTH OF THE WARM FRONT. AS OF
NOW, THE WARM FRONT LOOKS TO BE POSITIONED NORTH OF OUR REGION BY
12Z SUNDAY AS A SURFACE LOW LIFTS ACROSS THE EASTERN GREAT LAKES.
THIS SURFACE LOW THEN SLIDES TO THE CANADIAN MARITIMES SUNDAY NIGHT
INTO EARLY MONDAY, PULLING A COLD FRONT EVENTUALLY ACROSS OUR AREA.
GIVEN THE LARGE UPPER-LEVEL RIDGE ACROSS THE SOUTH, THIS BOUNDARY
SHOULD TEND TO STALL IN AN EAST-WEST FASHION MONDAY AND TUESDAY AS A
SURFACE HIGH BUILDS ACROSS THE GREAT LAKES. AS CYCLOGENESIS TENDS TO
TAKE SHAPE LATE TUESDAY AND WEDNESDAY IN THE CENTRAL PLAINS, THE
AFOREMENTIONED BOUNDARY SHOULD BEGIN TO MIGRATE NORTHWARD AS A WARM
FRONT UNDER A GRADUALLY INCREASING WAA REGIME. THE MAIN PUSH OF THE
WAA ATTM APPEARS TO STAY WEST OF OUR AREA LATE TUESDAY AND
WEDNESDAY. THEREFORE, WE WILL GO WITH A DRY FORECAST WITH THE
EXCEPTION OF SLIGHT CHC POPS FOR ANY LEFTOVER CONVECTION SUNDAY
EVENING WITH THE FRONT. DEPENDING ON THE COLD FRONT TIMING AND
POTENTIAL CLOUD COVER, SUNDAY COULD BE ANOTHER RATHER HOT AND HUMID
DAY BEFORE RELIEF ARRIVES FROM THE NORTHWEST.

&&

.AVIATION /20Z WEDNESDAY THROUGH SUNDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY AND SURROUNDING AREAS.

CONVECTION IS STARTING TO FIRE AHEAD OF THE PRE FRONTAL TROUGH AS
INSTABILITY INCREASES. SO FAR...THE WEAK MID LEVEL CAP REMAINS IN
PLACE...AND THE ACTIVITY IS FALLING APART AS IT MOVES EAST. AS
HEATING CONTINUES AND SYNOPTIC SCALE ASCENT INCREASES...THE CAP WILL
BE REMOVED.

FOR NOW...HAVE INDICATED CB REMARKS AS THE CAP REMAINS IN PLACE.
WILL HAVE TO ADD THUNDERSTORMS TO THE FORECAST AFTER 2100 UTC AS THE
CAP IS REMOVED. WOULD EXPECT TO SEE SCATTERED CONVECTION THROUGH
ABOUT 0000 UTC. AFTER THIS...THERE MAY BE A BROKEN LINE OF
CONVECTION THROUGH 0300 UTC...AND THIS COULD AFFECT ALL OF THE
TERMINALS.

WOULD EXPECT VFR CONDITIONS OUTSIDE OF CONVECTION....WITH LOCALIZED
IFR CONDITIONS NEAR THE CONVECTION. THE SURFACE FRONT ASSOCIATED
WITH THE CONVECTION SHOULD CROSS THE REGION BETWEEN 0300 UTC AND
0600 UTC FROM WEST TO EAST. BEHIND THE FRONT...WINDS WILL SHIFT ANDS
COULD GUST BRIEFLY...BUT THIS WAS NOT INCLUDED IN THE FORECAST.

THE GRADIENT DROPS OFF QUICKLY BEHIND THE FRONT...AND THIS COULD
ALLOW FOG TO DEVELOP AT KRDG AND KMIV...ESPECIALLY IF THESE
LOCATIONS SEE RAIN. AT THIS POINT...WOULD EXPECT NOTHING LESS THAN 4
SM WITH THE FOG THROUGH 1200 UTC.

OUTLOOK...
VFR CONDITIONS ARE EXPECTED THURSDAY. CONVECTIVE TEMPERATURES MAY BE
OUT OF REACH AS THE LOW LEVEL MOISTURE IS SCOURED BY THE FRONT. HAVE
INCLUDED A MENTION...BUT NO MORE THAN A FEW CUMULUS EXPECTED. WINDS
MAY GUST TO NEAR 20 KNOTS FOR A TIME FROM MID  MORNING TO EARLY
AFTERNOON THURSDAY.

VFR CONDITIONS ARE EXPECTED THURSDAY NIGHT AND FRIDAY. THERE COULD
BE A FEW THUNDERSTORMS WITH A WARM FRONTAL PASSAGE FRIDAY AFTERNOON
AND EVENING...AND PERHAPS A FEW SATURDAY. THERE IS A BETTER CHANCE
OF MVFR/IFR CONDITIONS IN THUNDERSTORMS LATER IN THE WEEKEND.

&&

.MARINE...
THE SOUTHWEST GRADIENT IS PRODUCING WIND GUSTS TO 15 KNOTS AT
TIMES...AND THIS IS KEEPING THE SEA BREEZE CIRCULATIONS AT BAY. THE
GRADIENT MAY INCREASE A BIT AHEAD OF THE COLD FRONT TONIGHT...BUT
NOT EXPECTING WIND GUSTS MORE THAN 20 KNOTS.

AS THE FRONT PASSES...THERE MAY BE A SMALL WINDOW FOR WIND GUSTS TO
NEAR 25 KNOTS (CLOSE TO 0700 UTC). RIGHT NOW...IT DOES NOT APPEAR TO
BE ENOUGH FOR A HEADLINE...BUT MAY HAVE TO BE WATCHED LATER TONIGHT.

WINDS WILL DROP OFF THURSDAY AS THE GRADIENT RELAXES IN THE
AFTERNOON. IN FACT...IT MAY DROP OFF ENOUGH FOR SEA AND LAND BREEZES
IN THE MID TO LATE AFTERNOON. AS THE WEAK HIGH PRESSURE CENTER GETS
OFFSHORE THURSDAY NIGHT...WINDS WILL BACK TO THE SOUTHWEST...AND MAY
GET TO NEAR 15 KNOTS.

EXPECTING A WARM FRONTAL PASSAGE FRIDAY AFTERNOON. THIS WILL ALLOW
THE SOUTH SOUTHWEST FETCH TO INCREASE...AND SEAS COULD GET CLOSE TO
5 FEET IN THE NORTHERN WATERS FRIDAY AFTERNOON OR FRIDAY EVENING. IN
ADDITION...THE GRADIENT COULD ALLOW WINDS TO GUST TO 20 KNOTS. THIS
WILL ULTIMATELY BE DETERMINED BY THE DEPTH OF THE MIXED
LAYER...WHICH IS OFTEN LOWER IN WARM AIR ADVECTION.

MAY SEE THE GRADIENT INCREASE ENOUGH FOR WINDS TO GET BACK TO SMALL
CRAFT LEVELS INT HE SOUTHWEST FLOW AHEAD OF THE COLD FRONT. AGAIN...
THIS WILL BE DETERMINED BY THE DEPTH OF MIXED LAYER...BUT THE
SOUTHWEST FLOW COULD BE MORE CONDUCIVE TO MIXING FOR SATURDAY NIGHT.
