Tornado in Pennsylvania, August 22, 2010

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
152 PM EDT SUN AUG 22 2010

.SYNOPSIS...
SHOWERY LOW PRESSURE CENTERED BETWEEN WILLIAMSPORT AND ELMIRA LATE
THIS MORNING WILL SHIFT SLOWLY EASTWARD AND BE LOCATED SOUTH OF
LONG ISLAND BY MONDAY MORNING AND THEN DRIFT EAST OUT TO SEA TUESDAY
INTO WEDNESDAY. ONE WEAK COOL FRONT WILL CROSS OUR REGION THIS
EVENING AND A STRONGER BACK DOOR COLD FRONT WILL MOVE SOUTHWEST
THROUGH OUR AREA LATER MONDAY OR MONDAY NIGHT BOTH WITH SHOWERS
AND VERY UNSETTLED WEATHER. HIGH PRESSURE WILL SLOWLY BUILD IN
FROM THE WEST LATE THIS WEEK.

&&

.NEAR TERM /UNTIL 7 PM THIS EVENING/...
1140 AM UPDATE IS FOR MORE SOUTHERLY COMPONENT TO THE WIND THIS
AFTERNOON AND SLIGHTLY STRONGER.

OTRW THE 9 AM UPDATE HOLDS FOR THE 1140 AM PACKAGE.

BLV A GOOD CHANCE OF SMW STORMS MIDDAY OR THIS AFTN.

ALSO BLV WE WILL NEED FLOOD ADVISORIES BY MID OR LATE AFTN...POSSIBLY
IN NJ AND NE PA.

SYNOPSIS HAS THE DETAILS OF THE FRONTS/LOW CENTER.

IAD SOUNDING LOOKS FAIRLY POTENT WITH SWEAT 300PLUS...50 KT AT
ABOUT 20000 FT AS WELL AS PWAT 2.06.

&&

.SHORT TERM /7 PM THIS EVENING THROUGH TUESDAY/...
TONIGHT INTO MONDAY MIDDAY...COULD BE A 12-18 HR BREAK IN SHOWERY
WX SE PA DEL NE MD AND S 2/3RDS NJ AS WEAK WLY COOL FRONT SHOVES
HIGH PWAT NEWD TOWARD LONG ISLAND BEFORE IT WASHES SWWD AGAIN LATE
MONDAY IN ASSN WITH THE FORMATION OF THE UPPER LOW NR PHL.

HOWEVER...NAM MODELS SECONDARY POOLING OF UNSTABLE AIR AROUND 00Z
THIS EVENING ALONG THE DEL RIVER AND SO SHOWERY WX INTO THE 02Z
SUNDAY TIME FRAME IS STILL A GOOD FORECAST AND THEN IT MAY BE DRY
THEREAFTER FOR 12-18 HRS. WILL AWAIT ALL 12Z GUIDANCE BEFORE ANY
ADJUSTMENTS IN THE TONIGHT-MONDAY TIME FRAME.

WITH THIS FEATURE IN PLACE WE WILL BE HARD PRESSED TO SEE MUCH
SUN OVER THE NEXT SEVERAL DAYS AND THEREFORE WILL KEEP THE
FORECAST CLOUDY THROUGH THE PERIOD. AS THE UPPER LOW STARTS TO
FALL APART AND BECOME MORE WAVE-LIKE IN NATURE, AS SURFACE HIGH
PRESSURE STARTS TO BUILD TOWARD THE REGION, WE MAY START TO SEE
LESS CLOUDS ACROSS THE REGION, ESPECIALLY OVER THE SOUTHERN ZONES.
HOWEVER, WE DO NOT EXPECT THIS TO OCCUR QUICKLY WITH CLOUDS LIKELY
REMAINING THROUGH AT LEAST THE MIDWEEK TIMEFRAME.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
AN UPPER LEVEL LOW PRESSURE TROUGH WILL ROTATE ACROSS OUR AREA
TUESDAY NIGHT AND THEN HEAD OFF TO THE EAST WEDNESDAY. THIS COULD
PRODUCE A FEW SHOWERS IN OUR AREA, ALTHOUGH PROBABILITIES WILL BE
IN THE SLIGHT CHANCE TO CHANCE CATEGORIES. A WEAK COLD FRONT IS THEN
FORECAST TO CROSS THE REGION LATE WEDNESDAY OR WEDNESDAY NIGHT
ACCOMPANIED BY SCATTERED SHOWERS OR THUNDERSTORMS. THE FRONT WILL
MOVE OFF TO THE EAST THURSDAY, ALLOWING A LARGE AREA OF HIGH
PRESSURE TO PUSH IN FROM THE WEST. THE HIGH WILL DOMINATE OUR
WEATHER WELL INTO THE WEEKEND. TEMPERATURES THROUGH THIS PERIOD WILL
AVERAGE NEAR OR SLIGHTLY BELOW NORMAL. THE COOLEST DAY WILL BE FRIDAY
WHEN HIGHS ARE IN THE 70S TO LOW 80S. THE REMAINDER OF THE DAYS
WILL SEE HIGHS IN THE MID 70S TO MID 80S. OVERNIGHT LOWS TUESDAY
NIGHT AND WEDNESDAY NIGHT WILL BE IN THE UPPER 50S AND 60S. THURSDAY
NIGHT AND FRIDAY NIGHTS, UNDER MOSTLY CLEAR SKIES, WILL HAVE LOWS
IN THE 50S TO MID 60S.

&&

.AVIATION /18Z SUNDAY THROUGH FRIDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY AND SURROUNDING AREAS.

COMPLEX AND DIFFICULT WEATHER IS UNFOLDING TODAY...AT LEAST IN SO
FAR AS THE DETAILS ARE CONCERNED...WHICH IS WHAT OUR USERS AND
CUSTOMERS WANT TO KNOW. MODEL GUIDANCE IS NOT EXACTLY IN LOCKSTEP...
AND WITH DIFFERENT GUIDANCE ONE MUST TRY TO ASSESS WHICH SOLUTION IS
MORE CORRECT. AS SUCH...CONFIDENCE IN THE LARGE-SCALE SITUATION IS
HIGH...BUT BECOMES LOW AS ONE MICROSCOPES TO THE DETAILS.

INITIALLY AT 18Z...LOW PRESSURE TO OUR NORTHWEST...WITH A TRAILING
COLD FRONT...IS EXPECTED TO MOVE EAST-SOUTHEASTWARD THIS EVENING AND
CAMP IN NORTHERN NEW JERSEY...FAR SOUTHEASTERN NEW YORK...AND THE
NEW YORK BIGHT AREA TONIGHT. SCATTERED TO NUMEROUS SHOWERS AND
ISOLATED THUNDERSTORMS WILL CONTINUE OVER THE TAF SITES THIS
AFTERNOON AND LIKELY DIMINISH GRADUALLY FROM WEST TO EAST THIS
EVENING AS THE FRONT MOVES EASTWARD AND DIURNAL EFFECTS SUBSIDE.
CEILINGS WERE IN THE PROCESS OF IMPROVING...AND MANY SITES HAD
ALREADY BECOME VFR EARLY THIS AFTERNOON.

SO...VFR CONDITIONS WILL BE FORECAST THIS AFTERNOON AND EARLY
TONIGHT AND THEN BE BROUGHT TO MARGINAL VFR CEILINGS OVERNIGHT...
WITH PATCHY FOG IN A TEMPO GROUP FOR THE RURAL TAF SITES...AS A GOOD
BIT OF RAIN HAS OCCURRED. THE WILD CARD IS THE WINDS. IF THEY
ACTUALLY BECOME WEST OR NORTHWEST AS THE NAM MOS PROGS...AND
MAINTAIN SOME SPEED SAY 5 KNOTS OR A LITTLE MORE...THEN THE
FOREGOING MAY WORK. IF WINDS DROP OR A SOUTHEAST OR EAST WIND
DEVELOPS AS THE GFS MOS SUGGESTS...THEN CONDITIONS COULD BE LOWER.

SO...AS THE FRONT WORKS OFFSHORE WINDS ARE EXPECTED TO BE MOSTLY A
WESTERLY COMPONENT TONIGHT. THEN...A SPOKE WORKING AROUND THE UPPER
LOW APPEARS TO MOVE THROUGH DURING MONDAY. AS THIS OCCURS...WINDS
SHOULD BACK TO NORTH AND NORTHEAST DURING MONDAY AS THE SURFACE
REFLECTION MOVES SOUTHWARD OR SOUTHEASTWARD...WITH WINDS BECOMING
NORTHEAST DURING MONDAY AFTERNOON FOR THE 30 HOUR KPHL TAF. WITH
MOISTURE AND SOME FORCING...A VICINITY REMARK WITH A CB APPENDED TO
THE STRATOCUMULUS WAS USED TO ADDRESS THE EXPECTED SCATTERED SHOWERS
AND ISOLATED THUNDERSTORMS DURING LATER MONDAY MORNING AND INTO THE
AFTERNOON.

OUTLOOK...
AS THE AREA IS EXPECTED TO RESIDE IN A NORTHEAST FLOW REGIME MONDAY
NIGHT AND TUESDAY LOW CONDITIONS...AT LEAST MARGINAL VFR AND LIKELY
IFR CEILINGS FOG AND PERHAPS SOME RAIN OR DRIZZLE ARE EXPECTED. AS
THE SYSTEM GRADUALLY MOVES AWAY WEDNESDAY, SOME IMPROVEMENT SHOULD
TAKE PLACE. LONG RANGE GUIDANCE WAS INDICATING THE POSSIBILITY OF
ANOTHER FRONT ABOUT THURSDAY.

&&

.MARINE...
AN AREA OF LOW PRESSURE AND ASSOCIATED COLD FRONT WILL GRADUALLY
SETTLE INTO OUR AREA TODAY. MEANWHILE, A WARM FRONT WILL SLOWLY LIFT
NORTHWARD DURING THE DAY. THIS WILL RESULT IN A SOUTH TO
SOUTHEASTERLY FLOW. THERE IS WAA AHEAD OF THESE FEATURES AND THE
LOW-LEVEL FLOW IS FORECAST TO INCREASE TODAY. THIS HAS ALREADY BEEN
EVIDENT IN RADAR VELOCITY AND VWP DATA. GIVEN THE WAA, THE LATEST
THINKING IS THAT THE WINDS REMAIN BELOW ADVISORY CRITERIA TODAY AND
TONIGHT. THE FORECAST SOUNDINGS INDICATE THE POTENTIAL FOR GUSTS 20
TO NEAR 25 KNOTS FOR A TIME TODAY, HOWEVER WILL MAINTAIN UNDER 25
KNOTS. THE SOUTHERLY FLOW WILL TEND TO BUILD THE SEAS SOME TODAY,
ALTHOUGH THE LATEST THINKING IS THAT ANY 5 FOOTERS THAT DEVELOP
REMAIN EAST OF OUR WATERS.

THE AFOREMENTIONED SURFACE LOW THEN SLIDES ACROSS OUR AREA BUT
SLOWLY MOVES EASTWARD AS THE TROUGH ALOFT CLOSES OFF IN THE
NORTHEAST TO MID ATLANTIC. THE MODEL GUIDANCE VARIES SOME IN THE
DETAILS WITH THE TRACK AND STRENGTH OF THIS SURFACE LOW AS IS GETS
OVER THE WATER AND SLIDES EASTWARD. IT DOES APPEAR THAT A TIGHTER
PRESSURE GRADIENT SETS UP ACROSS OUR NORTHERN WATERS LATER MONDAY
AND TUESDAY AS THE SURFACE LOW SLOWLY DEPARTS AND A SURFACE HIGH IS
NEAR NORTHERN NEW ENGLAND. THE 00Z GFS LOOKS LIKE IT IS A LITTLE
WEAKER WITH THE LOW-LEVEL FLOW NOW, ALTHOUGH IT MAY STILL BE TO
STRONG. THE ONSHORE FLOW SHOULD BUILD THE SEAS TO ABOUT 5 FEET,
ALTHOUGH HIGHER SEAS ARE SOMEWHAT QUESTIONABLE AS IT DEPENDS ON THE
DURATION OF THE ONSHORE FLOW. THEREFORE, WE DID NOT STRAY TO FAR
FROM CONTINUITY REGARDING SEAS AND NO ADVISORIES WILL BE ISSUED ATTM.

A WEAK AREA OF HIGH PRESSURE MOVES ACROSS WEDNESDAY, ALTHOUGH A
SECONDARY COLD FRONT ALSO APPEARS TO MOVE THROUGH. A LARGER HIGH
PRESSURE SYSTEM THEN LOOKS TO SETTLE IN FOR THURSDAY WITH NO
SIGNIFICANT WEATHER ANTICIPATED.
