The episode as NWS PHI wrote it up.
An area of low pressure moved across the eastern Great Lakes region during the morning of August 25th. A cold front associated with this low pressure system was located in the Ohio Valley. A hot and especially humid airmass was found ahead of this front across the Middle Atlantic region on August 25th. As the front approached, showers and thunderstorms developed and several of the storms became severe. The actual cold front however did not clear the region until the morning of the 26th.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
430 PM EDT SAT AUG 25 2007
.SYNOPSIS...
A COLD FRONT EXTENDED ACROSS THE EASTERN GREAT LAKES AND THE OHIO
RIVER VALLEY THIS AFTERNOON. THE FRONT WILL SINK TO THE SOUTH AND
EAST AND IT SHOULD REACH SOUTHEASTERN PENNSYLVANIA AND CENTRAL NEW
JERSEY AROUND DAYBREAK. THE BOUNDARY IS EXPECTED TO REMAIN NEARLY
STATIONARY ON SUNDAY BEFORE MOVING SLOWLY TO THE SOUTH AGAIN ON
SUNDAY NIGHT AND MONDAY. WEAK HIGH PRESSURE IS EXPECTED TO FOLLOW
FOR TUESDAY AND WEDNESDAY. ANOTHER COLD FRONT FROM THE NORTHWEST IS
FORECAST TO ARRIVE ON THURSDAY.
&&
.NEAR TERM /UNTIL 6 AM SUNDAY MORNING/...
BY LATE AFTERNOON, HEAT INDEX VALUES RANGED IN THE 100 TO 110
DEGREE RANGE IN MOST OF OUR FORECAST AREA. THE ONLY EXCEPTIONS
WERE THE HIGHER ELEVATIONS AND LOCATIONS ALONG THE COAST. DEW POINT
TEMPS WERE GENERALLY IN THE 70S. THE HEAT ADVISORY AND EXCESSIVE
HEAT WARNING WILL REMAIN IN PLACE UNTIL 8:00 PM TO ALLOW TEMPS TO
DROP BACK DOWN INTO THE 80S.
DURING THE AFTERNOON, A BIT OF A CAP REMAINED IN PLACE OVER OUR
FORECAST AREA INHIBITING THE DEVELOPMENT OF ANY CONVECTION.
HOWEVER, SHOWERS AND TSTMS WERE DEVELOPING TO OUR WEST OVER THE
SUSQUEHANNA RIVER VALLEY AND OVER NORTHERN VIRGINIA. THE CONVECTION
OVER NORTHERN VIRGINIA WAS MOVING TO THE NORTHEAST AND IF IT
MAINTAINS THE SAME RATE OF MOTION THAT IT HAD THIS AFTERNOON IT
SHOULD REACH PARTS OF THE UPPER DELMARVA AND SOUTHEASTERN
PENNSYLVANIA AROUND 9:00 PM. WITH THE LOW LEVEL MOISTURE IN PLACE,
CHANCES ARE THAT THE PRECIP WILL MAKE IT INTO PARTS OF OUR REGION
AFTER DARK, EVEN WITH THE LOSE OF DAYTIME HEATING.
THE STORM PREDICTION CENTER CONTINUES TO HAVE THE INTERSTATE 95
CORRIDOR AND POINTS TO THE NORTH AND WEST IN ITS AREA OF SLIGHT RISK
FOR SEVERE TSTMS. FOR NOW, WE HAVE THE MENTION OF SCATTERED SHOWERS
AND TSTMS FOR OUR NORTHWESTERN COUNTIES AND THE MENTION OF ISOLATED
SHOWERS AND TSTMS IN THE SOUTHEAST FOR TONIGHT. WELL CONTINUE TO
MONITOR THE DEVELOPMENT TO OUR WEST AND WELL MAKE ADJUSTMENTS TO
THE FORECAST IF NEED BE.
&&
.SHORT TERM /6 AM SUNDAY MORNING THROUGH TUESDAY/...
WITH THE COLD FRONT SINKING SLOWLY SOUTH AND EAST THROUGH OUR
FORECAST AREA ON SUNDAY, WEVE MAINTAINED THE CHANCE POPS FOR OUR
ENTIRE REGION. WITH A LITTLE MORE IN THE WAY OF CLOUD COVER, TEMPS
SHOULD BE A LITTLE COOLER ON SUNDAY. ALSO, DEW POINT TEMPS MAY DROP
BY A FEW DEGREES. AS A RESULT, THERE DOES NOT SEEM TO BE A NEED TO
EXTENDED THE HEAT ADVISORY OR THE EXCESSIVE HEAT WARNING.
FOR SUNDAY NIGHT, WELL NEED TO LINGER CHANCE POPS FOR ALL BUT OUR
NORTHERN TWO TIERS OF COUNTIES, AND FOR MONDAY WELL KEEP THE
MENTION OF PRECIP FOR PHILADELPHIA AND FOR POINTS TO THE EAST AND
SOUTH.
IT LOOKS AS THOUGH THE FRONT WILL SINK FAR ENOUGH TO THE SOUTH TO
ALLOW WEAK HIGH PRESSURE TO BUILD ACROSS OUR REGION FOR TUESDAY.
&&
.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
A MID AND UPPER LEVEL RIDGE SHOULD TRY TO NOSE UP INTO OUR REGION
DURING THE MID WEEK PERIOD BEFORE A LONG WAVE TROUGH BEGINS TO DIG
DOWN FROM THE NORTHWEST FOR THURSDAY AND FRIDAY. THE ASSOCIATED
COLD FRONT IS FORECAST TO REACH US LATE ON WEDNESDAY NIGHT. A WAVE
OF LOW PRESSURE MAY DEVELOP ALONG THE BOUNDARY, CAUSING ITS PROGRESS
TO SLOW A BIT. HIGH PRESSURE SHOULD EVENTUALLY BUILD DOWN FROM THE
NORTHWEST FOR NEXT WEEKEND.
&&
.AVIATION /21Z SATURDAY THROUGH THURSDAY/...
SCATTERED LIGHT HAZE AND MVFR VSBYS REMAINS OVER THE REGION,
OTHERWISE VFR CONDITIONS ARE BEING OBSERVED AS HEATING HAS
DISSIPATED THE MORNING CLOUDS AND FOG. THESE CLOUDS AND FOG ARE NOT
EXPECTED TO RETURN TONIGHT AS THE TROPICAL AIRMASS HAS NOW
OVERSPREAD THE ENTIRE AREA. A COLD FRONT COMING IN FROM THE NW
COULD TRIGGER TSTMS TONIGHT AND IF THESE FORM, IFR CONDITIONS AND
GUSTY WINDS WITH HEAVY RAIN ARE POSSIBLE IN ANY TSTMS. OUTSIDE OF
SHOWERS AND TSTMS VFR CONDITIONS SHOULD CONTINUE. THE TAFS ONLY
MENTION SCATTERED STRATOCU AND CB AFTER 00Z AT ABE/RDG AND AFTER 03Z
AT PHL/PNE/ACY/MIV/ILG TO INDICATE TSTM PSBLTY. WHEN TSTMS DO FORM,
THEN THE TAFS WILL BE UPDATED ACCORDINGLY. ON SUNDAY, THE FRONT
STALLS ACROSS THE REGION AND SCATTERED TSTMS REMAIN POSSIBLE THROUGH
A GOOD PORTION OF THE DAY.
EVEN THOUGH THE FRONT IS SOUTH OF THE REGION, SOME TSTMS COULD
LINGER INTO SUNDAY NIGHT OR MONDAY. THE NEXT THREAT OF TSTMS IS
NEXT WED NIGHT OR THURSDAY.
&&
.MARINE...
SCA FLAGS ARE NOT ANTICIPATED THROUGH THU. WINDS WERE 10 TO 15 KT
AND MAY INCREASE TO AROUND 15 KT WITH 20 KT GUSTS TONIGHT AHEAD OF A
COLD FRONT. THE COLD FRONT WILL STALL TO THE WEST SUNDAY AND KEEP A
S OR SW FLOW OVER THE REGION, BUT SPEEDS SHOULD REMAIN BELOW 20 KT.
SEAS WERE ALSO 2-4 FT AND ARE NOT EXPECTED TO INCREASE. THEN THE
FRONT MOVES THROUGH THE FORECAST WATERS SUNDAY EVENING AND KEEPS
MOVING SOUTH UNTIL IT STALLS OVER SOUTHERN DELMARVA. THIS MEANS,
SINCE DRY AIR WILL BE SLOW TO MOVE IN. TSTMS COULD FORM LATER
TONIGHT AND SUNDAY AHEAD OF AND WITH THE COLD FRONT. THEN TSTMS
REMAIN PSBL INTO MONDAY AS THE FRONT MOVES SOUTH VERY SLOWLY BEFORE
HIGH PRESSURE BUILDS IN EARLY NEXT WEEK. THE GRADIENT REMAINS WEAK
INTO MIDWEEK AND WINDS SPEEDS AS WELL AS WAVE HEIGHTS SHOULD REMAIN
BELOW SCA CRITERIA.
