Area forecast discussion, Jul 23, 1:37 PM EDT, 1 hour 47 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
137 PM EDT FRI JUL 23 2010
.SYNOPSIS...
A WARM FRONT WILL MOVE NORTHWARD THROUGH OUR AREA TODAY...BRINGING A
HOTTER AND MORE HUMID AIR MASS ESPECIALLY SATURDAY AND INTO
SUNDAY. A COLD FRONT WILL CROSS THE REGION SUNDAY...WITH HIGH
PRESSURE EXPECTED FOR THE FIRST PART OF NEXT WEEK.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
TEMPERATURES WILL BE A FEW DEGREES HOTTER TODAY AS COMPARED WITH
THURSDAY. BASED ON THE LWX SOUNDING, A FLIRTATION WITH 100 DEGREES
IS EXPECTED OVER THE FAR SOUTHERN ZONES. DEWPOINTS HAVE NOT MIXED
OUT IN THE SOUTHERN AREAS AS MUCH AS PREVIOUSLY EXPECTED. THIS HAS
RESULTED IN HEAT INDICES EXCEEDING 105, WHICH IS THE HEAT ADVISORY
CRITERION. THEREFORE WE HAVE ISSUED A HEAD ADVISORY FOR
SOUTHEASTERN NEW JERSEY AS WELL AS MUCH OF THE DELMARVA. THE
IMMEDIATE COASTAL ZONES WERE NOT INCLUDED AS THE SEA BREEZE MAY
KEEP THEIR TEMPERATURES A FEW DEGREES COOLER.
A WARM FRONT IS SLOWLY TRYING TO MOVE NORTH OF THE AREA THIS
AFTERNOON. REMNANT ACTIVITY FROM THE CONVECTION TO OUR NORTHWEST
WAS MOVING ACROSS OUR NORTHERN ZONES, AND POPS WERE ADJUSTED
ACCORDINGLY. THIS IS ASSOCIATED WITH A DECENT MID LEVEL IMPULSE
AND LOWER LEVEL THETA E ADVECTION OVER THE FRONT. IT ALL IS
EXPECTED TO SLIDE BY LATE THIS MORNING OR EARLY THIS AFTERNOON AS
THE WARM FRONT LIFTS NORTH, AND THEN THERE ACTUALLY MAY BE A BREAK
BEFORE ANOTHER IMPULSE IS PROGGED ON THE 00Z ECMWF AND THE 12Z NAM
FOR MAINLY THE FIRST PART OF THE SHORT TERM. SINCE SPC CONTINUES
TO PUT THE NORTHERN AND SOME OF THE CENTRAL PART OF THE AREA IN A
SLIGHT RISK, WE WON'T TAKE OUT THE AFTERNOON CHANCE POPS OR
ENHANCED WORDING.
MID AND HIGH CLOUDS WILL BE PREVALENT ACROSS THE NORTH AND CENTRAL
THIS MORNING, SHADING DOWN TO LOW TO MODERATE CLOUD AMOUNTS SOUTH.
CLOUDS WILL LIKELY DECREASE IN AMOUNT MORE SO FOR THE SOUTHERN AND
CENTRAL ZONES LATER TODAY WITH THE WARM FRONTAL PASSAGE.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH SUNDAY/...
THE GRIDS WERE NOT ALTERED VERY MUCH FROM WHAT WAS INHERITED FOR THE
SHORT TERM PORTION OF THE FORECAST. THE EXCESSIVE HEAT WATCH WILL BE
MAINTAINED FOR SATURDAY FOR PHILADELPHIA AND THE SURROUNDING URBAN
ZONES. THE 00Z GFS MOS GUIDANCE WAS ACTUALLY ONE DEGREE LOWER FOR
ITS MAXIMUM TEMPERATURE FOR PHILADELPHIA THAN ON THE 18Z RUN...BUT
BOTH WERE HIGHER THAN THE 12Z RUN. THE NAM MOS WAS UNCHANGED...BUT A
BIT LOWER THAN THE GFS MOS. THE NAM FOUS HAS FORECAST 32C FOR ITS T1
TEMPERATURE FOR LATE SATURDAY AFTERNOON...SO THE HIGHER GFS MOS WITH
A HIGH OF 100 WAS FORECAST FOR PHILADELPHIA.
SINCE TEMPERATURES BACK OFF SLIGHTLY FOR SUNDAY WITH THE COLD
FRONTAL PASSAGE...AND DEW POINTS DROP DURING THE DAY...IT WAS
DECIDED TO NOT EXTEND THE EXCESSIVE HEAT WATCH INTO SUNDAY.
ISOLATED/SCATTERED CONVECTION CENTRAL/NORTH SATURDAY WAS MAINTAINED.
SPC HAS ADDED OUR FAR NORTHWEST TO THEIR DAY 2 SLIGHT RISK
OUTLOOK...AND THIS WILL BE ADDED TO THE HAZARDOUS WEATHER OUTLOOK.
CHANCE SHOWER/THUNDERSTORM POPS NORTH AND CENTRAL...AND SLIGHT
CHANCE SOUTH...WERE RETAINED FOR SUNDAY GIVEN THE CONTINUING
INSTABILITY...THE PROXIMITY OF THE FRONT JUST TO OUR EAST AND SOUTH
OR EVEN IN OUR EASTERN AND SOUTHERN ZONES...AND AN UPPER SHORT WAVE
PASSAGE.
&&
.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
AT THE BEGINNING OF THE PERIOD, A COLD FRONT WILL BE SLIDING THROUGH
THE REGION AND OFFSHORE. BEHIND THIS FRONT, HIGH PRESSURE CENTERED
OVER THE GREAT LAKES WILL BUILD EASTWARD INTO THE AREA LATE SUNDAY
NIGHT AND THROUGH THE DAY ON MONDAY. THIS HIGH WILL BE THE MAIN
WEATHER FEATURE OVER THE REGION THROUGH TUESDAY AND INTO WEDNESDAY,
ALTHOUGH A WARM FRONT FROM THE SOUTH WILL BEGIN TO ADVANCE NORTHWARD
TOWARD OUR AREA DURING WEDNESDAY.
HIGH PRESSURE ON MONDAY AND TUESDAY WILL ALLOW COOLER TEMPERATURES
AND A DRIER AIR MASS TO SETTLE IN ACROSS THE AREA. FOR THE MOST
PART, HIGH TEMPS WILL RANGE FROM THE LOWER 80S ACROSS THE NORTH TO
THE UPPER 80S ACROSS THE SOUTHERN ZONES. THIS WILL FEEL
CONSIDERABLY NICER WITH DEW POINTS EXPECTED TO RANGE FROM THE 50S
TO THE LOWER 60S. WITH THE APPROACHING WARM FRONT ON WEDNESDAY, IT
WILL BEGIN TO FEEL MORE HUMID WITH DEW POINTS RISING INTO THE 60S,
BUT HIGH TEMPERATURES ON WEDNESDAY SHOULD STILL RANGE FROM THE
LOWER 80S NORTH TO THE UPPER 80S ACROSS THE SOUTH. CHANCE POPS ARE
INCLUDED FOR WEDNESDAY NIGHT THROUGH THURSDAY AS THE WARM FRONT
APPROACHES AND MOVES THROUGH THE AREA. A SLIGHT CHANCE IS INCLUDED
THROUGH THURSDAY NIGHT.
&&
.AVIATION /17Z FRIDAY THROUGH TUESDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY AND SURROUNDING AREAS.
A GENERAL VFR FORECAST WAS ISSUED WITH THE 18Z TAFS, BUT WITH A
COUPLE OF CAVEATS. ORGANIZED CONVECTIVE ACTIVITY THROUGH THIS TIME
PERIOD IS EXPECTED TO REMAIN JUST TO THE NORTH OF OUR TERMINALS
WHICH PLACES CONFIDENCE OF THIS FORECAST VERIFYING LOWEST AT KABE
AND HIEST AT KACY AND KMIV.
FOR THIS AFTERNOON CONVECTIVE TRIGGERS ARE EXPECTED TO BE LACKING
JUST WEST OF THE TERMINALS WITH BASICALLY SOME HIGH BASED VFR CU AND
OR AC DEBRIS AROUND. THE TRIGGERS FOR SHOWERS AND THUNDERSTORMS ARE
AROUND LAKE ERIE, BUT THE GENERAL WIND FLOW IS WEST TO EAST. UNDER
THIS SCENARIO THE OVERALL FLOW WILL PUT UP RESISTANCE TO ANY
SOUTHWARD MOVEMENT TO THE CONVECTION. WE EXPECT THE LINE OF
ORGANIZED CONVECTION TO COME CLOSEST TO KABE AND THIS IN ALL
LIKELIHOOD WOULD OCCUR EARLY THIS EVENING. OTHERWISE AN INCREASING
SW FLOW IS FORECAST FOR THIS AFTERNOON WITH SOME GUSTINESS TO ABOUT
20KTS AT THE TERMINALS. THE SEA BREEZE FRONT HAS MADE IT TO KACY AND
EASTERN OCEAN COUNTY. THE INCREASING SW FLOW ALOFT SHOULD FIGHT ANY
WESTWARD MOVEMENT AND CONFIDENCE ABOUT THE WIND DIRECTION AT KACY IS
NOT HIGH AS THE FRONT MIGHT VACILLATE NEAR IT.
FOR THIS EVENING AND OVERNIGHT, WE ARE EXPECTING THE ORGANIZED
CONVECTION TO COME CLOSE BUT REMAIN NORTH OF OUR TERMINALS. BECAUSE
OF THE LOW CONFIDENCE WE ONLY CARRIED CB AS A CLOUD TYPE AT KABE,
KACY AND KTTN. MOST OF THE CURRENT MODELS ARE KEEPING SHOWERS AND
THUNDERSTORMS NORTH OF THE PHL LOCAL AREA. WE ARE EXPECTING SOME
DEBRIS CLOUDINESS AROUND, MORE NORTH OF KPHL. SOME MODELS ARE
SHOWING ANOTHER UPPER AIR DISTURBANCE MOVING THROUGH AFTER MIDNIGHT.
CONSENSUS IS TOO LOW ABOUT THIS OCCURRING TO REFLECT IT AT ANY OF
THE TERMINALS. WE HAVE CONTINUED THE TREND OF SHOWING SOME HAZE
FORMING TOWARD MORNING. WE KEPT VSBYS AS EITHER MVFR OR JUST BARELY
VFR WHERE STRONGER SURFACE WINDS WERE FORECAST.
A VERY HOT AND HUMID DAY IS FORECAST FOR SATURDAY, BUT WITH
BASICALLY VFR CONDITIONS. SOME SCATTERED TO WIDELY SCATTERED SHOWERS
AND THUNDERSTORMS ARE FORECAST, BUT THE CHANCES AND CONFIDENCE OF
ONE AT THIS FORECAST JUNCTURE AFFECTING THE TERMINALS IS TOO LOW TO
CARRY OR MENTION AS A CB CLOUD GROUP. THE GENERAL WIND FLOW IS
EXPECTED TO BE MORE OUT OF THE WEST AND IN SPITE OF HIGHER
TEMPERATURES, THE SEA BREEZE FRONT SHOULD REMAIN EAST OF THE
TERMINALS.
OUTLOOK...
SOME MARGINAL VFR TO BRIEFLY IFR CONDITIONS ARE POSSIBLE AS SHOWERS
AND THUNDERSTORMS ASSOCIATED WITH THE COLD FRONT MOVE THROUGH OUR
AREA LATER SATURDAY INTO SUNDAY. GOOD VFR CONDITIONS ARE EXPECTED
SUNDAY NIGHT INTO TUESDAY. THE NEXT CHANCE FOR MVFR OR BRIEFLY IFR
CONDITIONS WILL BE WITH AN APPROACHING WARM FRONT LATE TUESDAY
NIGHT INTO WEDNESDAY.
&&
.MARINE...
00Z/23 GFS WW GUIDANCE WILL PROBABLY BE TRIMMED SLIGHTLY TONIGHT.
NO HEADLINE ISSUANCE ATTM BUT ITS POSSIBLE SEAS OF 4-5 FT WILL
OCCUR IN THE OUTER E EDGE OF THE ATLC COASTAL WATERS TONIGHT.
WE STILL THINK THE 00Z/23 GFS IS OVER FORECASTING THE WINDS ON THE
COOLER OCEAN WATER AND THUS THE SEAS ARE OVER FORECAST SLIGHTLY AS
WELL. FOR THE 3RD SUCCESSIVE FORECAST SHIFT...WE TOO SHAVED ABOUT
A FOOT OFF THE WAVE WATCH GUIDANCE FOR TONIGHT.
A COLD FRONTAL PASSAGE ON SUNDAY WILL SHIFT THE WINDS TO THE WEST,
BUT SPEEDS ARE FORECAST TO REMAIN BELOW SMALL CRAFT ADVISORY
CRITERIA. THE STRONGEST WINDS ARE FORECAST TO OCCUR DURING THE
DAY WHEN THE AIR WILL REMAIN WARMER THAN THE BAY AND OCEAN TEMPS.
WINDS MIGHT REACH SMALL CRAFT ADVISORY CRITERIA NEAR THE IMMEDIATE
SHORE AND INLETS AND WE WILL CONTINUE TO MONITOR FUTURE MODEL
TRENDS FOR THIS POSSIBILITY. STARTING SUNDAY NIGHT WINDS AND SEAS
SHOULD DIMINISH/DECREASE AS A HIGH PRESSURE SYSTEM APPROACHES ON
MONDAY AND REACHES CLOSE TO IF NOT OVER THE AREA WATERS COME
TUESDAY.
