Heat in Pennsylvania, May 30, 2011

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
834 AM EDT MON MAY 30 2011

.SYNOPSIS...
HIGH PRESSURE ANCHORED OFF THE MID ATLANTIC COAST WILL BRING HOT AND
HUMID CONDITIONS TO THE REGION TODAY. A WEAK COLD FRONT WILL DROP
ACROSS THE REGION TONIGHT...THEN DISSIPATE. HIGH PRESSURE OFF THE
NEW ENGLAND COAST WILL BRING AN ONSHORE FLOW TO THE REGION TUESDAY
INTO TUESDAY NIGHT. A COLD FRONT WILL APPROACH THE AREA WEDNESDAY...
CROSSING THE REGION WEDNESDAY NIGHT. HIGH PRESSURE WILL BUILD IN
BEHIND THE FRONT FOR THE END OF THE WEEK.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
THE LAST OF THE LINE OF SHOWERS AND THUNDERSTORMS THAT AFFECTED
THE CWA EARLIER HAS MOVED OVER THE WATERS AND WILL CONTINUE OUT
TO SEA. THE DEBRIS CLOUDINESS WITH THE ACTIVITY WILL TAKE A BIT
LONGER TO CLEAR THE REGION...AND SOME STRATUS HAS DEVELOPED IN THE
WAKE OF THE CONVECTION. MOST OF THIS SHOULD THIN BY 900 AM...AND
THE LOW LEVELS SHOULD BE STABILIZED BY THE ACTIVITY. BACK TO THE
WEST... THE CLOUDS THIN TO CIRRUS...AND SKIES SHOULD BECOME MOSTLY
SUNNY LATER THIS MORNING.

FOR THE MOST PART...THE REGION SHOULD BE TOO CAPPED FOR CONVECTION
FOR THE REMAINDER OF THE DAY...OUTSIDE THE NORTHERN FRINGES. IN
THESE AREAS...LOWER CONVECTIVE TEMPERATURES AND A WEAKER CAP COULD
ALLOW WIDELY SCATTERED CONVECTION TO DEVELOP BEFORE CAPPING HALTS
THE DEVELOPMENT. THE COLUMN LOOKS TOO WARM FOR ANYTHING BUT SMALL
HAIL WITH THE CONVECTION...BUT DRY SUBCLOUD LAYERS COULD ALLOW FOR
GUSTY WINDS. THE ACTIVITY IS NOT EXPECTED TO BE WIDESPREAD ENOUGH
TO MENTION GUSTY WINDS IN THE GRIDDED OR TEXT FORECASTS.

THE MAIN FORECAST PROBLEM FOR TODAY WILL BE THE HEAT. THE 0000 UTC
MODEL SUITE IS SUGGESTING THE SHALLOW COLD FRONT OVER NEW ENGLAND
THIS MORNING WILL DROP ACROSS THE AREA THIS AFTERNOON AND THIS
EVENING. IT WOULD APPEAR AS THOUGH THE ACTIVITY THIS MORNING WILL
HELP PUSH THE FRONT SOUTHWEST...AS HIGH PRESSURE STARTS TO DEVELOP
EAST OF THE NORTHERN NEW ENGLAND COAST.

THIS COULD HAVE A COUPLE OF IMPLICATIONS FOR THE HEAT PORTION OF THE
FORECAST. WINDS AWAY FROM THE WATER SHOULD BECOME WEST AHEAD OF THE
FRONT FOR MUCH OF THE AREA. THIS COULD ALLOW TEMPERATURES TO RISE A
BIT MORE THAN THE GFS MOS NUMBERS FOR HIGHS...AND THE HIGH
TEMPERATURE FORECAST IS MORE OF A MOS BLEND FOR THIS AFTERNOON.

IN ADDITION...THE MORE WESTERLY FLOW IN THE BOUNDARY LAYER COULD
ALLOW DRIER AIR TO MIX FROM ABOVE...WHERE DEW POINTS PLUMMET AT THE
TOP OF THE MIXED LAYER (WHICH SHOULD BE ABOUT 5000 FEET). THE DRIER
AIR COULD ALLOW DEW POINTS TO MIX OUT INTO THE LOWER TO MID 60S. THE
SUM OF THESE IMPLICATIONS MAY END UP WASHING OUT...AND HEAT INDEX
VALUES IN THE HIGHLY URBANIZED AREAS MAY END UP NEAR 95 DEGREES THIS
AFTERNOON IN ANY EVENT.

SINCE THE HEAT ADVISORY IS IN PLACE NOW...THERE DOES NOT SEEM TO BE
ENOUGH EVIDENCE TO BUMP THIS UP TO A WARNING FOR THE AFTERNOON. IF
THE DEW POINT FORECAST IS TOO LOW FOR THIS AFTERNOON...A SHORT FUSED
EXCESSIVE HEAT WARNING MAY BE NEEDED FOR THE URBANIZED AREAS.

THE SLIGHTLY DRIER AIR SHOULD BUMP CONVECTIVE TEMPERATURES INTO THE
MID TO UPPER 90S. CUMULUS DEVELOPMENT OUTSIDE OF THE LEHIGH
VALLEY...SOUTHERN POCONOS AND NORTHWEST NEW JERSEY COULD BE MINIMAL
BECAUSE OF THIS. SO...AFTER THE DEBRIS CLOUDINESS ASSOCIATED WITH
THE MORNING CONVECTION EXITS...SKIES SHOULD BECOME MOSTLY SUNNY.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY/...
ANY LATE AFTERNOON OR EARLY EVENING CONVECTION SHOULD END QUICKLY THIS
EVENING. THERE APPEARS TO BE ANOTHER MCS FORMING IN SOUTHEAST SOUTH
DAKOTA EARLY THIS MORNING. THIS MCS SHOULD PASS NORTH OF THE AREA
TONIGHT AS MID LEVEL HEIGHTS PEAK TONIGHT...AND THE BEST THERMAL
INFLOW REMAINS CLOSER TO THE CANADIAN BORDER. THIS WILL HAVE TO BE
WATCHED...AND A CHANCE OF SHOWERS AND THUNDERSTORMS MAY NEED TO BE
ADDED IF THIS FEATURE LOOKS TO BE A THREAT FOR LATER TONIGHT.

OTHERWISE...SKIES SHOULD BECOME MOSTLY CLEAR. THE AIRMASS CONTINUES
TO WARM FROM WITHIN...SO SOME HAZE AND PATCHY FOG IS POSSIBLE ALTER
TONIGHT. THE PASSAGE OF THE BACKDOOR FRONT MAY NOT HAVE THAT MUCH
IMPACT ON TEMPERATURES TONIGHT...SO LOWS WERE BASED MAINLY ON A MOS
BLEND.

THE MAIN IMPACT OF THE FRONTAL PASSAGE COULD BE TUESDAY. THE 0000
UTC MODEL SUITE SUGGESTS AN EAST THEN SOUTHEAST FLOW FOR MUCH OF THE
AREA TUESDAY. THE EXCEPTION HERE COULD BE THE LEHIGH VALLEY...WHERE
THE LOW LEVEL FLOW MAY NOT MODIFY ENOUGH TO MAKE MUCH DIFFERENCE
WITH REGARD TO TEMPERATURE.

WHILE 850 MB TEMPERATURES CONTINUE TO SUPPORT HIGHS IN THE LOWER TO
MID 90S AWAY FROM THE SEA AND BAY BREEZES TUESDAY...THE LOWER LEVELS
MAY BE MODIFIED BY THE ONSHORE FLOW. THIS IS REFLECTED IN THE MOS
NUMBERS FOR HIGHS TUESDAY. THE 0000 UTC NAM MOS NUMBERS MAY END UP
BEING TOO LOW...AS THE LOW LEVEL FLOW MAY NOT BE MODIFIED AS MUCH IN
THE WARM AIRMASS IN PLACE. HIGHS TUESDAY WERE MAINLY BASED ON THE
WARMER GFS MOS NUMBERS.

THE COMBINATION OF TEMPERATURES AND DEW POINTS IN THE 60S WILL KEEP
THREAT FOR HEAT INDEX VALUES TO REACH EXCESSIVE HEAT WARNING
CRITERIA. THIS IS NOT AS MUCH AS SLAM DUNK AS IT SEEMED THIS TIME
SUNDAY...DUE TO THE POTENTIALLY GREATER IMPACT OF THE FLOW BEHIND
THE FRONT. WITH THIS IN MIND...THE WATCH REMAINS IN EFFECT BUT WILL
NOT BE CONVERTED TO A WARNING THIS MORNING.

WITH THE MID LEVEL HEIGHTS PEAKING MONDAY NIGHT AND TUESDAY...THE
MID LEVEL TEMPERATURE SHOULD REMAIN WARM...AND MOST OF THE AREA
SHOULD BE TOO CAPPED FOR CONVECTION. THIS IS IN SPITE OF A DECENT
AMOUNT OF INSTABILITY. MODIFIED MODEL SOUNDINGS SUGGEST THAT THE CAP
MAY BE WEAK ENOUGH ACROSS THE LEHIGH VALLEY AND SOUTHERN POCONOS FOR
A MENTION OF SHOWERS AND THUNDERSTORMS...BUT FOR NOW THIS WILL BE
THE ONLY PLACE WHERE CONVECTION WILL BE MENTION.

THE EVENING CONVECTION SHOULD DISSIPATE QUICKLY TUESDAY NIGHT. THERE
ARE SOME HINTS THAT...AS MID LEVEL HEIGHTS START TO FALL...THAT AN
MCS COULD AFFECT THE AREA LATE TUESDAY NIGHT OR EARLY WEDNESDAY
MORNING. THERE IS NOT A LOT OF CONFIDENCE IN THIS SOLUTION...AND
THERE IS TIME TO WORK THIS OUT. FOR NOW...A SLIGHT CHANCE OF SHOWERS
AND THUNDERSTORMS WILL BE INCLUDED FOR TUESDAY NIGHT ACROSS WESTERN
AND NORTHERN AREAS. LOWS TUESDAY NIGHT WERE GENERALLY A BLEND OF MOS
NUMBERS.

THE LOW LEVEL FLOW SHOULD VEER TO THE SOUTHWEST AGAIN WEDNESDAY...AS
THE SURFACE GRADIENT INCREASES AHEAD OF THE COLD FRONT. THIS WILL
MITIGATE THE LOW LEVEL COOLING WITH THE BACKDOOR FRONT...AND ALLOW
THE COLUMN TO WARM AGAIN. 850 MB TEMPERATURES AGAIN SUGGEST THAT MOS
NUMBERS MAY BE TOO LOW FOR HIGH TEMPERATURES. THE COMBINATION OF
HIGHS AND INCREASING DEW POINTS SUPPORT THE CONTINUATION OF THE
EXCESSIVE HEAT WATCH FOR WEDNESDAY.

HEIGHTS CONTINUE TO FALL IN THE MID LEVELS WEDNESDAY AHEAD OF A
SHORT WAVE IN THE NORTHERN STREAM. THIS WILL ALLOW THE SURFACE COLD
FRONT TO APPROACH FROM THE WEST. SURFACE CONVERGENCE SHOULD BE
BETTER WEDNESDAY AFTERNOON AHEAD OF THE FRONT...AS WHATEVER
SOUTHEAST BOUNDARY LAYER FLOW THAT REMAINS SHOULD BE ERASED. MODELS
SHOULD A GOOD DEAL OF INSTABILITY AWAY FROM THE INFLUENCE OF THE
WATER FOR LATE WEDNESDAY MORNING AND DURING THE AFTERNOON.

THE CAPPING SHOULD BE GONE AT THIS POINT...AND MODIFIED MODEL
SOUNDINGS SHOW THE COMBINATION OF INCREASING SHEAR AND INSTABILITY
COULD LEAD TO DEEP CONVECTION AHEAD OF THE FRONT DURING THE
AFTERNOON AND EVENING HOURS. RIGHT NOW...WILL NOT GO TOO HIGH WITH
THE CHANCES...AS THERE ARE INDICATIONS THAT THE LOW LEVEL FLOW COULD
BECOME WESTERLY...AND THIS WOULD DECREASE SURFACE CONVERGENCE. IF
CONVECTION DEVELOPS...AN ENVIRONMENT FAVORING MULTICELL STORMS COULD
RESULT IN LINE SEGMENTS AHEAD OF THE FRONT.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
THE COLD FRONT THAT WILL MOVE INTO OUR AREA WEDNESDAY WILL BE
MOVING OFF TO THE SOUTH AND EAST WEDNESDAY NIGHT. A FEW SHOWERS
AND THUNDERSTORMS MAY LINGER INTO THE EARLY PART OF THE NIGHT,
ESPECIALLY SOUTHERN AND EASTERN PORTIONS OF THE FORECAST AREA.
HIGH PRESSURE WILL THEN MOVE IN WITH A DRIER AND SLIGHTLY COOLER
AIR MASS FOR THURSDAY. THIS SHOULD BRING AN END TO OUR HEAT WAVE
AS HIGHS ON THURSDAY ARE EXPECTED TO RANGE FROM THE MID 70S TO THE
MID 80S. THE FAIR DRY WEATHER WILL CONTINUE THURSDAY NIGHT INTO
FRIDAY AS THE HIGH PRESSURE SYSTEM DRIFTS ACROSS OUR REGION.
A WEAK WARM FRONT IS FORECAST TO CROSS THE REGION LATE FRIDAY
INTO SATURDAY. THIS COULD POSSIBLY TOUCH OFF A FEW SCATTERED
SHOWERS AND THUNDERSTORMS. THE HIGH PRESSURE SYSTEM WILL THEN
REASSERT ITSELF LATER SATURDAY INTO SUNDAY. COULD BE A FEW
SHOWERS AND THUNDERSTORMS AGAIN LATE SUNDAY AS A WEAK COLD
FRONT APPROACHES FROM THE NORTHWEST. BUT FOR THE MOST PART,
THIS ENTIRE TIME PERIOD SHOULD BE HIGHLIGHTED BY FAIR WEATHER
WITH TEMPERATURES JUST SLIGHTLY ABOVE NORMAL. LIKE THURSDAY,
DAYTIME HIGHS FRIDAY THROUGH SUNDAY WILL RANGE FROM THE MID 70S
TO MID 80S. OVERNIGHT LOWS WILL BE IN THE 50S TO MID 60S, WITH
THE HIGHEST LOWS ALONG SOUTHERN COASTAL AREAS. THERE COULD EVEN
BE A FEW UPPER 40S IN OUR COLDER MOUNTAIN VALLEYS THURSDAY NIGHT.

&&

.AVIATION /13Z MONDAY THROUGH FRIDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY AND SURROUNDING AREAS.

A WEAKENING COLD FRONT IS FORECAST TO SETTLE ACROSS THE AREA DURING
THE COURSE OF TODAY INTO TONIGHT. THIS COULD BE REINFORCED SOME BY
THUNDERSTORMS GENERALLY TO OUR NORTH. IT APPEARS THAT THE CLUSTER OF
THUNDERSTORMS EARLY THIS MORNING WILL TRACK NORTH OF OUR NORTHERN
MOST TERMINALS, THEREFORE NO MENTION INCLUDED AT THIS TIME. WILL
MONITOR IN THE EVENT OF RENEWED DEVELOPMENT ON THE SOUTHERN EDGE OR
THE ACTIVITY TURNS A BIT MORE TO THE SOUTHEAST. IF ANY TERMINAL
WOULD BE IMPACTED, IT SHOULD BE LIMITED TO KABE. OTHERWISE,
CONVECTIVE CLOUD DEBRIS MAINLY IN THE FORM OF HIGH CLOUDS MOVES
THROUGH DURING THE MORNING. THE POOLING LOW-LEVEL MOISTURE EARLY
THIS MORNING MAY RESULT IN POCKETS OF LOW CLOUDS. THIS HAS BEEN
TRYING TO DEVELOP ALONG THE COASTAL SECTIONS OF NEW JERSEY, BUT SO
FAR HAS LITTLE SUCCESS. OVERALL THOUGH, DID NOT FAVOR MUCH IN THE
WAY OF STRATUS GIVEN THE SHIFTING WINDS JUST ABOVE THE SURFACE. SOME
FOG SHOULD BE AROUND EARLY THIS MORNING, ALTHOUGH THIS MAY TEND TO
BE LIMITED WITH SOME OF THE HIGH LEVEL CLOUDS MOVING THROUGH.

THE MAIN FORECAST ITEM FOR TODAY SHOULD BE THE WIND SHIFT AS A
WEAKENING COLD FRONT DROPS THROUGH THE AREA. THIS WILL ALLOW A
SOUTH/SOUTHWEST WIND TO SHIFT TO THE WEST AND NORTHWEST BUT SPEEDS
SHOULD BE 10 KNOTS OR LESS. THERE IS THE POTENTIAL THAT THE FLOW
REMAINS LIGHT ENOUGH THROUGH THE SHIFTING PHASE, THAT SEA, BAY AND
RIVER BREEZES DEVELOP. WE HINTED AT THIS AT KACY, KILG AND KPHL FOR
NOW AS CONFIDENCE IS ON THE LOWER SIDE REGARDING HOW THIS MAY OR MAY
NOT PLAY OUT. GIVEN THE WARMTH OF THE AIRMASS TODAY, CUMULUS
DEVELOPMENT SHOULD BE LIMITED.

THE FLOW REMAINS ON THE LIGHT SIDE TONIGHT WITH THE LOW-LEVEL
MOISTURE REMAINING ON THE HIGHER SIDE. THIS MAY TEND TO RESULT IN
SOME LOCALIZED FOG LATE.

OUTLOOK...
TUESDAY...PERHAPS SOME POCKETS OF SUB-VFR TO START DUE TO FOG,
OTHERWISE VFR WITH A SOUTHEASTERLY WIND UP TO 10 KNOTS. THERE COULD
BE ISOLATED THUNDERSTORMS DEVELOPING IN THE AFTERNOON NORTH AND WEST
OF KABE AND KRDG. THERE IS THE POTENTIAL FOR A CLUSTER OF
THUNDERSTORMS TO DEVELOP TO OUR WEST AND PERHAPS MOVE INTO PARTS OF
OUR AREA OVERNIGHT /CONFIDENCE LOW REGARDING THIS/.

WEDNESDAY...PERHAPS SOME SHOWER OR THUNDERSTORM ACTIVITY TO START
/LOW CONFIDENCE/, THEN SOME THUNDERSTORMS SHOULD DEVELOP IN THE
AFTERNOON AS A COLD FRONT ARRIVES. SOME STORMS COULD BE LOCALLY
STRONG. OVERALL VFR, WITH THE EXCEPTION OF IN AND NEAR ANY
SHOWERS/STORMS.

THURSDAY...OVERALL VFR WITH NORTHWESTERLY WINDS. A COLD FRONT
SETTLES TO THE SOUTH THEN STALLS.

FRIDAY...VFR WITH A WARM FRONT TRYING TO WORK NORTHWARD. WINDS MAY
TEND TO BE LIGHT, OWING TO SEA/BAY BREEZE DEVELOPMENT.

&&

.MARINE...
A WEAKENING COLD FRONT WILL SLOWLY MOVE THROUGH THE AREA TODAY INTO
TONIGHT. THIS WILL ALLOW FOR A WIND SHIFT TO EVENTUALLY TAKE PLACE.
THE OVERALL WIND FIELD REMAINS ON THE WEAKER SIDE, THEREFORE THE
WINDS ARE EXPECTED TO REMAIN BELOW 15 KNOTS. AS THE FLOW OVER LAND
BECOMES MORE WEST AND NORTHWEST TODAY, IT MAY TEND TO KEEP THE
SEA BREEZE CLOSER TO THE COAST. THE SOUTHERLY FLOW AHEAD OF THE COLD
FRONT REMAINS LIGHT ENOUGH WHERE SEAS HAVE NOT REALLY CHANGED MUCH.
THE WAVEWATCH GUIDANCE HAS GONE BACK AND FORTH SOME REGARDING 5 FOOT
SEAS. THIS LOOKS TO BE MOSTLY CONFINED TO THE OUTER EDGE OF OUR
COASTAL WATER ZONES, IF THEY DO INDEED BUILD TO THAT HEIGHT.
THEREFORE, WE WILL CONTINUE WITH NO SMALL CRAFT ADVISORY.

THE SURFACE COLD FRONT LOOKS TO STALL TO OUR SOUTH TUESDAY AND
POSSIBLY WASH OUT. THIS OCCURS AS UPPER-LEVEL RIDGING BUILDS
EASTWARD SOME. THIS SHOULD RESULT IN A SOUTH OR SOUTHEAST WIND
TUESDAY, WHICH MAY BECOME ENHANCED SOME UP DELAWARE BAY AND
NEARSHORE. A PRE-FRONTAL TROUGH MAY MOVE THROUGH WEDNESDAY MORNING
WITH A WIND SHIFT FROM THE SOUTH AND PERHAPS A SHOWER OR
THUNDERSTORM. THE NEXT COLD FRONT MOVES THROUGH LATE WEDNESDAY INTO
THURSDAY. SOME STORMS COULD BE STRONG AHEAD OF THE COLD FRONT
WEDNESDAY. AN OFFSHORE FLOW SHOULD RESULT IN THE WAKE OF THIS FRONT.
THE FRONT MAY THEN STALL TO OUR SOUTH THURSDAY BEFORE TRYING TO MOVE
NORTHWARD AS A WARM FRONT FRIDAY. OVERALL, CONDITIONS WERE KEPT
BELOW ADVISORY CRITERIA.
