The episode as NWS LWX wrote it up.
Gulf of Mexico and Atlantic moisture associated with the remnants of Tropical Depress Lee continued to interacted with a nearly stationary boundary across West Virginia. Widespread rain falling across already saturated ground in eastern West Virginia resulted in flooding in Grant County. A storm spotter in Kline Gap measured a storm total of 4.35 inches of rain.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC
316 PM EDT TUE SEP 6 2011
.SYNOPSIS...
A WARM FRONT WILL SLOWLY PASS THROUGH THE AREA THROUGH WEDNESDAY.
TROPICAL MOISTURE WILL OVERRUN THE BOUNDARY CAUSING LOCALLY HEAVY
RAIN DURING THIS TIME. A PROLONGED PERIOD OF RAIN WILL LINGER
THROUGH MUCH OF THE WORK WEEK...AS LEE BECOMES AN UPPER LOW
STATIONED OVER THE OHIO VALLEY.
&&
.NEAR TERM /THROUGH WEDNESDAY/...
THE REMNANTS OF WHAT WAS TROPICAL STORM LEE BOTH AT THE UPPER AND
LOWER LEVELS OF THE ATMOSPHERE WILL CONTINUE TO MOVE THROUGH THE
TENNESSEE VALLEY. A COUNTER CLOCKWISE FLOW AROUND THIS SYSTEM HAS
ALLOWED FOR DEEP MOISTURE TO MOVE INTO OUR REGION FROM THE GULF OF
MEXICO AND ATLANTIC OCEAN. A STATIONARY BOUNDARY EXTENDS NORTH AND
EAST FROM THE SURFACE LOW ACROSS SOUTHERN AND EASTERN VIRGINIA INTO
THE DELMARVA PENINSULA. AS TROPICAL MOISTURE OVERRIDES THE
BOUNDARY...RAIN IS EXPECTED TO CONTINUE THROUGH LATE THIS AFTERNOON.
LOCALLY HEAVY RAIN IS EXPECTED DUE TO THE HIGH MOISTURE CONTENT IN
THE ATMOSPHERE. A FLASH FLOOD WATCH REMAINS IN EFFECT FOR THE ENTIRE
AREA.
THE STATIONARY BOUNDARY IS EXPECTED TO SLOWLY DRIFT NORTH AND WEST
AS A WARM FRONT TONIGHT. AS THE FLOW VEERS TO THE SOUTHEAST
THUNDERSTORMS MAY BECOME ROOTED WITHIN THE BOUNDARY LAYER ACROSS
EXTREME LOWER SOUTHERN MARYLAND. MODERATE DIRECTIONAL AND SPEED
SHEAR AT THE LOW-LEVELS OF THE ATMOSPHERE DOES SUGGEST THAT AN
ISOLATED TORNADO COULD DEVELOP WITH ANY STORMS THAT BECOME ROOTED
WITHIN THE BOUNDARY LAYER. LOCALLY HEAVY RAIN IS EXPECTED TONIGHT
ACROSS THE REST OF THE AREA AS TROPICAL MOISTURE CONTINUES TO
OVERRUN THE BOUNDARY.
THE REMNANTS OF LEE WILL CONTINUE TO MOVE THROUGH THE OHIO VALLEY
WEDNESDAY WHILE THE WARM FRONT STALLS OUT NEAR THE BLUE RIDGE
MOUNTAINS WEDNESDAY AFTERNOON. A COLD FRONT ASSOCIATED WITH THE
SURFACE LOW WILL SLOWLY MOVE INTO THE POTOMAC HIGHLANDS WEDNESDAY
AFTERNOON. A BAND OF HEAVY SHOWERS ARE EXPECTED ALONG AND AHEAD OF
THIS BOUNDARY WEDNESDAY MORNING ACROSS THE POTOMAC HIGHLANDS AND
SHENANDOAH VALLEY. AS THE BOUNDARY SLOWLY PROGRESSES EASTWARD THE
HEAVY SHOWERS WILL MOVE TOWARD THE WASHINGTON AND BALTIMORE
METROPOLITAN AREAS LATE IN THE DAY. A SHEAR VECTOR PARALLEL TO THIS
BOUNDARY SUGGESTS THAT HEAVY SHOWERS WILL TRAIN OVER THE SAME AREAS
FOR AN EXTENDED PERIOD OF TIME CAUSING LOCALLY HEAVY RAINFALL. A
FLASH FLOOD WATCH REMAINS IN EFFECT THROUGH WEDNESDAY.
THERE MAY BE A FEW BREAKS OF SUNSHINE BEHIND THE WARM FRONT
WEDNESDAY AFTERNOON ESPECIALLY FOR LOCATIONS EAST OF THE BLUE
RIDGE MOUNTAINS. ANY SUNSHINE THAT DOES DEVELOP WILL CAUSE MODERATE
AMOUNTS OF INSTABILITY TO DEVELOP. MODERATE INSTABILITY WILL BRING A
CHANCE FOR T-STORMS LATE WEDNESDAY MORNING AND AFTERNOON. WITH
PLENTY OF LOW-LEVEL SPEED AND DIRECTIONAL SHEAR BEHIND THE WARM
FRONT ANY T-STORMS THAT DO DEVELOP WILL BE CAPABLE OF PRODUCING
ISOLATED TORNADOES.
&&
.SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/...
UPPER LOW IS FORECAST TO REMAIN OVER THE OHIO VALLEY THROUGH THE END
OF THE WEEK. CWA WILL REMAIN IN A RELATIVELY HIGH PRECIPITABLE WATER
ENVIRONMENT. IT LOOKS AS IF AN AXIS OF CONVERGENCE WILL REMAIN OVER
THE CWA AS WELL...NOT TO MENTION SHORTWAVES EJECTED FROM THE BASE OF
THE UPPER LOW. RESULT WILL BE A CONTINUATION OF UNSETTLED CONDITIONS
ACROSS THE CWA. POPS REMAIN ABOVE CLIMATOLOGY AND WITH THE GROUND
ALREADY SATURATED AT THAT POINT ANY ADDITIONAL RAINFALL MAY
PROMOTE/EXACERBATE FLOODING PROBLEMS.
GIVEN CLOUDS/UNSETTLED CONDITIONS...CONTINUED TO FORECAST HIGH
TEMPERATURES THURSDAY/FRIDAY BELOW MOS VALUES AND NEAR MOS VALUES
AT NIGHT.
&&
.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
GUIDANCE SHOWS A STAGNANT PATTERN CONTINUING INTO THE WEEKEND. WHAT
REMAINS OF TROPICAL STORM LEE WILL RETROGRADE SLIGHTLY FROM ITS
LOCATION OVER EASTERN TENNESSEE TO PERSIST AS A STACKED UPPER LEVEL
LOW OVER THE CENTRAL CONUS. THIS WILL ASSIST IN FUNNELING MOISTURE
FROM THE GULF INTO THE CWA THROUGH THE WEEKEND. DUE TO THE ABUNDANT
MOISTURE AVAILABLE...SHOWERS AND THUNDERSTORMS ARE POSSIBLE EACH
DAY. MODERATE DAYTIME HIGHS IN THE LOW 80S WITH OVERNIGHT LOWS IN
THE LOW TO MID 60S ARE EXPECTED EACH DAY. THE LATEST TRACK FROM THE
HURRICANE CENTER FOR KATIA SHOWS THE CENTER MOVING ABOUT 450 MILES
TO THE EAST OF THE DELMARVA COAST. FLOW AROUND KATIA WILL ALSO
ASSIST IN CHANNELING MOISTURE RICH AIR INTO THE CWA FOR FRIDAY AND
SATURDAY.
SUNDAY LOOKS TO START A POSSIBLE DRYING TREND FOR THE EXTENDED
PERIOD. THE STACKED LOW OVER THE CONUS WILL BEGIN TO DRIFT OFF THE
ATLANTIC THROUGH THE BEGINNING OF THE WEEKEND TRANSITIONING
PREVAILING MID AND UPPER LEVEL FLOW FROM SOUTHWEST TO NORTHWEST.
RIGHT NOW...MONDAY LOOKS TO HAVE JUST A SLIGHT CHANCE FOR PRECIP.
&&
.AVIATION /19Z TUESDAY THROUGH SUNDAY/...
RAIN ALONG WITH IFR CIGS/VSBYS ARE EXPECTED ACROSS THE TERMINALS
THROUGH TONIGHT. SUBIFR CIGS AND VSBYS ARE EXPECTED LATE THIS
EVENING INTO EARLY WEDNESDAY MORNING.
A WARM FRONT WILL PASS THROUGH THE TERMINALS WEDNESDAY MORNING WHILE
A COLD FRONT SLOWLY APPROACHES LATE WEDNESDAY AFTERNOON. A BAND OF
HEAVY SHOWERS AND SCATTERED THUNDERSTORMS ARE EXPECTED ALONG AND
AHEAD OF THE COLD FRONT. CIGS MAY IMPROVE LATER WEDNESDAY MORNING
BEHIND THE WARM FRONT...BUT LOCALLY HEAVY RAIN WILL REDUCE CIGS AND
VSBYS AT ANY TIME. A WIND SHIFT TO THE SOUTHEAST IS EXPECTED BEHIND
THE WARM FRONT WEDNESDAY MORNING. ANY T-STORMS THAT DO DEVELOP
WEDNESDAY WILL HAVE THE POTENTIAL TO PRODUCE AN ISOLATED TORNADO.
AFTER POSSIBLE IMPROVED CONDITIONS IN TERMS OF PREVAILING VSBYS/CIGS
WEDNESDAY AFTERNOON...EXPECT CONDITIONS TO DEGRADE BACK TO IFR FOR
WEDNESDAY NIGHT AS EASTERLY FLOW CONTINUES. MVFR-IFR RESTRICTIONS
MAY PERSIST INTO THE END OF THE WEEK DURING THE NIGHTTIME AND
MORNINGS WITH RELATIVE IMPROVEMENTS EACH AFTERNOON.
VISIBILITY REDUCTIONS AS WELL AS LOW CEILINGS DUE TO CONTINUING
SHOWERS WILL BE POSSIBLE ACROSS ALL TERMINALS THROUGH THE
BEGINNING OF THE WEEKEND. CONDITIONS COULD BEGIN TO IMPROVE SUNDAY
AS THE CLOSED UPPER LEVEL LOW OVER THE CONUS BEGINS TO DRIFT OFF
THE ATLANTIC COAST.
&&
.MARINE...
WILL CONTINUE WITH A SMALL CRAFT ADVISORY THROUGH TONIGHT FOR THE
WATERS. NORTHEAST WINDS AHEAD OF A WARM FRONT WILL SHIFT TO THE
SOUTHEAST BEHIND THE WARM FRONT TONIGHT INTO WEDNESDAY. SHOWERS
AND SCATTERED THUNDERSTORMS WILL PRODUCE LOCALLY HEAVY RAINFALL THAT
CAN REDUCE VSBYS THROUGH WEDNESDAY. ANY THUNDERSTORMS THAT DO
DEVELOP WILL HAVE THE POTENTIAL TO PRODUCE AN ISOLATED WATERSPOUT
SOUTH OF DRUM POINT LATE THIS AFTERNOON THROUGH TONIGHT AND ACROSS
ALL OF THE WATERS WEDNESDAY.
A SMALL CRAFT ADVISORY IS IN EFFECT WEDNESDAY FOR THE THE MARYLAND
PORTION OF THE CHESAPEAKE BAY AND LOWER TIDAL POTOMAC RIVER.
EAST/SOUTHEAST WINDS CONTINUE WEDNESDAY NIGHT THROUGH FRIDAY. WILL
HAVE TO WATCH POTENTIAL FOR SCA WINDS CONTINUING INTO WEDNESDAY
NIGHT...BUT DID NOT HAVE THE CONFIDENCE IN CRITERIA BEING MET BEYOND
WEDNESDAY AFTERNOON. ASIDE FROM THAT...SHOWRS AND ISOLATED
THUNDERSTORMS WILL RESULT IN LOCAL VISIBILITY RESTRICTIONS.
THE PRIMARY MARINE CONCERNS FOR THE EXTENDED PERIOD ARE VISIBILITY
REDUCTIONS DUE TO SHOWERS AND THUNDERSTORMS. THE UPPER LEVEL PATTERN
WILL BEGIN TO TRANSITION AT THE END OF THE WEEKEND CAUSING DECLINING
PRECIPITATION CHANCES FOR THE BEGINNING OF THE WORK WEEK.

ALONG THE POTOMAC RIVER BASIN.
FLASH FLOOD WATCH REMAINS IN EFFECT THROUGH 22Z WED...AS PTNL FOR
HVY RN CONTS. FLASH FLOOD WATCH MAY BE NEEDED WEDNESDAY NIGHT
ESPECIALLY FOR LOCATIONS ALONG AND EAST OF THE SHENANDOAH VALLEY.
THROUGH WED...AN ADDITIONAL 2 TO 4 INCHES IS XPCD ALONG/W OF BLUE
RIDGE...WITH 1 TO 3 INCHES ELSEWHERE. LOCALLY HIGHER AMOUNTS IN
EXCESS OF 5 INCHES ARE POSSIBLE IN HEAVIER BANDS OF SHOWERS.
RISK FOR HVY RN CONTS THU/FRI AS LOPRES TO WEST ALLOWS RICH MOISTURE
TO STREAM NWD INTO MID-ATLC.
&&
.TIDES/COASTAL FLOODING...
A NORTHERLY FLOW HAS ALLOWED ANOMALIES TO DECREASE TODAY.
HOWEVER...THE SURFACE WIND IS EXPECTED TO SHIFT TOWARD THE
SOUTHEAST TONIGHT INTO WEDNESDAY BEHIND A WARM FRONT. TIDAL
ANOMALIES WILL INCREASE DURING THIS TIME AND MINOR FLOODING IS
POSSIBLE NEAR TIMES OF HIGH TIDE WEDNESDAY.
ISSUED COASTAL FLOOD WATCH FROM WEDNESDAY EVENING THROUGH FRIDAY
MORNING. WILL HAVE TO CONTEND WITH POSITIVE TIDAL ANOMALIES AND
SOUTHEAST FLOW BUILDING UP WATER IN THE BAY AND UP THE TIDAL
POTOMAC. THIS WOULD LIKELY RESULT IN AT LEAST MINOR TIDAL FLOODING
AND POSSIBLY MODERATE FLOODING. IN ADDITION...WILL HAVE TO WORRY
ABOUT FRESHWATER EFFECTS AFFECTING AREAS NEAR THE UPPER TIDAL
POTOMAC TOWARD THE END OF THE WEEK.
