The episode as NWS PHI wrote it up.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
1126 AM EDT SUN MAR 14 2010
.SYNOPSIS...
LOW PRESSURE OVER THE DELMARVA PENINSULA WILL MOVE SLOWLY EASTWARD
AND OFFSHORE THIS AFTERNOON. IT WILL STALL OFF THE NEW JERSEY AND
DELAWARE COASTS TONIGHT, THEN LOOP SOUTH AND EAST MONDAY AND
MONDAY NIGHT BEFORE HEADING WELL OFFSHORE TUESDAY. HIGH PRESSURE
OVER THE NORTHERN PLAINS TUESDAY WILL SINK SOUTHEASTWARD AND REACH
THE SOUTHEASTERN STATES FRIDAY...AND THEN MOVE OFFSHORE SATURDAY.
A COLD FRONT IS FORECAST TO APPROACH THE AREA SATURDAY.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
AT ATTEMPT IS BEING MADE TO STAY AHEAD OF THE CURVE TODAY...BY
NOTING THAT THE VORTICITY LOBE THAT GENERATED THE SHOWERS AND
ISOLATED TO SCATTERED CONVECTION THIS MORNING WAS MOVING WESTWARD
THROUGH THE AREA AT LATE MORNING. THIS WAS BRINGING AN END TO THE
PRECIPITATION OVER EASTERN AREAS, AND A BACK EDGE WAS MOVING
THROUGH THE WESTERN HALF OF OUR AREA. SO, THE HIGH PROBABILITIES
WILL BE KEPT FOR THE WESTERN ZONES FOR A FEW HOURS INTO EARLY
AFTERNOON...THEN DROP BACK TO CHANCE POPS LIKE EVERYWHERE ELSE
FOR THE REST OF THE AFTERNOON. ISOLATED CONVECTION WILL BE
KEPT...BUT THE ATMOSPHERE DOES APPEAR TO BE STABILIZING AND THE
NEW NAM FOUS SHOWS THIS. THE EARLIER CONVECTION WAS ABLE TO
GENERATE SMALL HAIL...ALTHOUGH ONE SPOTTER DID REPORT UP TO NICKEL
SIZE...INDICATING QUITE STRONG UPWARD VERTICAL MOTION FOR MARCH.
ALSO...PRECIPITATION AMOUNTS WERE ENHANCED FOR THE WESTERN ZONES
EARLY...BUT LOWERED FOR THE REST OF THE AFTERNOON ELSEWHERE.
OTHERWISE, A FEW TEMPERATURE AND DEW POINT ADJUSTMENTS WERE MADE
BASED ON CURRENT READINGS AND MOS OUTPUT.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH TUESDAY/...
IT WOULDN'T BE THIS COLD SEASON WITHOUT ANOTHER PIVOTING/LOOPING
SURFACE LOW PRESSURE SYSTEM AND WE WILL GET ONE TONIGHT AND MONDAY.
AS THE UPPER LOW MOVES OFFSHORE TONIGHT, IT WILL CAPTURE OUR
DEPARTING LOW AND FORCE IT TO LOOP BACK TOWARD OUR CWA ON MONDAY.
PRECIPITATION THAT IS DEVELOPING OFF THE SOUTH CAROLINA COAST
EVENTUALLY TAKES THE CIRCUITOUS ROUTE BACK INTO OUR CWA LATER
TONIGHT AND MONDAY. POPS TONIGHT AND MONDAY WILL FAVOR THE EASTERN
PART OF OUR CWA AND PRECIPITATION SHOULD BE MORE STRATIFORM IN
NATURE. THERE IS NO FORECAST INSTABILITY AND RAINFALL AMOUNTS ARE
NOT EXPECTED TO BE EXCESSIVE. ENOUGH COLDER AIR DOES START TO WORK
INTO THE NORTHERN PART OF OUR CWA THAT SOME SNOW SHOULD START MIXING
IN AT THE HIGHER TERRAIN LOCATIONS. GFS FORECAST SOUNDINGS ARE STILL
SHOWING SLEET POTENTIAL FOR MONDAY WHILE THE ECMWF AND WRF-NMM DO
NOT SHOW AS MUCH OF A COLD LAYER AROUND 925MB. WE WILL CONTINUE TO
MONITOR THE PROGRESSION OF THE COLD AIR, BUT THE GFS HAS BEEN A BIT
TOO BULLISH WITH TRYING TO INJECT COLD AIR INTO OUR AREA WITH THIS
SYSTEM. WINDS SHOULD START INCREASING AGAIN ON MONDAY AS THE LOW
PRESSURE SYSTEM MOVES OFFSHORE. RIGHT NOW IT APPEARS THAT THEY
SHOULD REMAIN BELOW ADVISORY CRITERIA.
THE LOW WILL START MOVING OFFSHORE ON MONDAY NIGHT AND PRECIPITATION
SHOULD PULL EAST ALONG WITH IT. BECAUSE OF THE SLOWER TIMING AND
LARGER LOOP, WE DID ADD POPS FOR MONDAY NIGHT ADD BRING THE CHANCES
FOR SOME SNOW TO MIX IN SOUTHEAST OF THE POCONOS. MOST OF THE
PRECIPITATION SHOULD BE OVER BY MIDNIGHT. FOR TONIGHT THROUGH MONDAY
NIGHT STAT GUIDANCE WAS PRETTY CLOSE AND WE FOLLOWED THEM FOR MIN
AND MAX TEMPS.
THE SUN WILL RETURN ON TUESDAY ALONG WITH A STRETCH OF DRIER
WEATHER.
&&
.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
DRY WEATHER IS EXPECTED THROUGH MUCH OF THE EXTENDED FORECAST AT
THIS TIME. HIGH PRESSURE WILL TRY TO NOSE IN BEHIND THE DEPARTING
LOW PRESSURE SYSTEM AS IT MOVES OUT TO SEA TUESDAY NIGHT. AN AREA OF
LOW PRESSURE WILL BE SLIDING TO OUR NORTH AROUND FRIDAY NEAR THE
MAINE/CANADIAN BORDER WHICH MAY DRAG A WEAK FRONTAL BOUNDARY CLOSE
TO OUR AREA. HOWEVER, MOST OF THE PRECIPITATION ASSOCIATED WITH THIS
SYSTEM IS EXPECTED TO REMAIN NORTH OF OUR AREA. AT THE SAME TIME,
ANOTHER LOW PRESSURE SYSTEM IS EXPECTED TO REMAIN WELL TO OUR SOUTH
AND EAST OUT OVER THE OCEAN, BUT WILL STILL NEED TO BE WATCHED. THE
BEST CHANCE OF PRECIPITATION IN THE EXTENDED FOR OUR AREA IS
EXPECTED TO BE SOMETIME NEXT WEEKEND WITH THE PASSAGE OF A COLD
FRONT, BETWEEN LATE SATURDAY AND LATE SUNDAY. THE GFS BRINGS THE
FRONT AND PRECIPITATION AS EARLY AS LATE SATURDAY, WHILE THE ECMWF
BRINGS IT THROUGH LATER ON SUNDAY. THIS IS VERY LATE IN THE
EXTENDED, AND WILL BECOME BETTER DEFINED OVER THE NEXT SEVERAL DAYS.
TEMPERATURES ARE EXPECTED TO REMAIN FAIRLY CONSISTENT THROUGH MUCH
OF THE EXTENDED WITH BOTH HIGHS AND LOWS A FEW DEGREES ABOVE NORMAL.
&&
.AVIATION /15Z SUNDAY THROUGH THURSDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY AND SURROUNDING AREAS.
WIDESPREAD IFR CONDITIONS (CIGS) ARE EXPECTED TODAY AS A SLUG OF
RAIN AND EMBEDDED THUNDERSTORMS MOVE NORTHWEST THROUGH THE REGION.
PRECIPITATION SHOULD BE COMING TO END THIS AFTERNOON FROM THE EAST TO THE
WEST.
LOW PRESSURE WILL DRIFT ACROSS THE REGION TODAY THEN OFF THE COAST
TONIGHT. WINDS SHOULD BE NE TODAY AND THEN BACK AROUND TO N LATER
TODAY AND REMAIN N TONIGHT.
OUTLOOK...
THE LOW PRESSURE SYSTEM OFF THE COAST BACKS UP AND ONCE AGAIN
APPROACHES FROM THE EAST MONDAY. THE WIDESPREAD LOW CONDITIONS
SHOULD REMAIN THROUGH MONDAY AND PART OF MONDAY NIGHT. VFR
CONDITIONS MAY ARRIVE BY TUE MORNING. MUCH OF THE TUE-THU PERIODS
LOOKS VFR.
&&
.MARINE...
SCA CONDITIONS WILL PREVAIL THROUGH TODAY AND TONIGHT WITH VERY
ROUGH SEAS. WINDS WILL REMAIN OUT OF THE EAST-NORTHEAST TODAY AND
SHIFT MORE TO THE NORTH TONIGHT. MOST OF THE SHOWERS AND
THUNDERSTORMS ARE WELL TO THE WEST OF OUR WATERS EXCEPT FOR PARTS OF
THE NORTHERN DELAWARE BAY. THIS SHOWERS WILL CONTINUE TO PULL TO THE
NORTHWEST AS THE CENTER OF THE LOW PRESSURE INCHES CLOSER TO OUR
REGION.
LOW PRESSURE WILL DRIFT ACROSS THE WATERS TODAY AND HEAD EAST. THE
LOW WILL STRENGTHEN A BIT AND THEN RETROGRADE BACK WEST TOWARD THE
WATERS ON MON. SCA FLAG (FOR WINDS AND SEAS) WILL CONTINUE EARLY
THIS WEEK. WAVE GUIDANCE SUGGESTS THAT 5FT SEAS (OR GREATER) INTO
THU.
&&
.HYDROLOGY...
THE SMALLEST STREAMS THROUGHOUT THE AREA HAVE ALL CRESTED AND
RECEDED BACK INTO THEIR BANKS AFTER EXPERIENCING DRAMATIC RISES IN
RESPONSE TO HEAVY RAIN ON SATURDAY.
