AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC
1247 PM EDT WED SEP 7 2011

.SYNOPSIS...
LOW PRESSURE OVER EASTERN TENNESSEE AND AN ASSOCIATED WARM FRONT
ACROSS NORTH CAROLINA WILL SLOWLY LIFT NORTH ACROSS THE AREA
TODAY. TROPICAL MOISTURE WILL OVERRUN THE BOUNDARY CAUSING LOCALLY
HEAVY RAIN. A PROLONGED PERIOD OF RAIN WILL LINGER THROUGH MUCH OF
THE WORK WEEK...AS THE LOW LINGERS IN THE OHIO VALLEY.

&&

.NEAR TERM /THROUGH TONIGHT/...
HAVE CANCELLED THE WESTERN PORTION OF THE FLASH FLOOD WATCH. BASED
ON LATEST RADAR TRENDS AND GFS MODEL THE HEAVIEST AXIS OF RAIN
LOOKS TO SET UP EAST OF THIS AREA...AFFECTING AREAS ALONG AND TO
THE EAST OF THE BLUE RIDGE THROUGH THIS EVENING WHERE THE FLASH
FLOOD WATCH CONTINUES. LOCALLY 5 INCHES OR MORE OF RAINFALL IS
POSSIBLE ALONG THE INTERSTATE 95 CORRIDOR GIVEN THE
EFFICIENT/HEAVY RAINFALL FROM STORMS AND THE TRAINING WHICH IS
EXPECTED.

FLASH FLOODING IS NOT THE ONLY RISK. AS THE FRONT NEAR THE BAY
TILTS WEST...THERE SHOULD BE SOME INSTABILITY THAT DEVELOPS NEAR
THE INTERSTATE 95 CORRIDOR. WIND FIELDS WILL BE CONDUCIVE FOR
BOTH DIRECTIONAL AND SPEED SHEAR. THUS...DAMAGING WIND GUSTS IN
LINE SEGMENTS AND ALSO ISOLATED TORNADOES ARE A RISK THIS
AFTERNOON INTO EARLY EVENING.

WHILE THE SEVERE/TORNADO RISK SHOULD WANE IN THE EARLY
EVENING...HEAVY RAINFALL MAY LAST WELL INTO THE EVENING.

&&

.SHORT TERM /THURSDAY THROUGH FRIDAY/...
BOTH THE SFC AND UPPER LOWS WL REMAIN OVER THE OHIO VALLEY THU-FRI.
THEREFORE...THE CWFA 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 /18Z WEDNESDAY THROUGH MONDAY/...
CIGS WILL TEND TO IMPROVE TO MVFR AT MTN/BWI/DCA AS THE FRONT TILST
NORTHWEST...HOWEVER BANDS OF HEAVY RAINFALL AND THUNDERSTORMS
TRAINING FROM SOUTH TO NORTH WILL LIKELY PRODUCE IFR VSBYS. IFR
CIGS AT IAD WILL LINGER LONGER BEFORE POSSIBLE IMPROVEMENT AFTER
18Z...AND HEAVIEST AXIS OF RAINFALL SHOULD ALSO GENERALLY STAY
EAST OF THERE THROUGH AT LEAST 18Z. MRB MAY NOT SCOUR OUT AN IFR
CIG AT ALL.

EXPECT CONDITIONS TO DEGRADE BACK TO IFR AT ALL SITES FOR
TONIGHT 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...
HAVE HOISTED SCA...GIVEN 18+ KT GUSTS OCCURRING UP THE CHESAPEAKE
BAY. TPLM2 GUSTED TO 20 KT AT THE TOP OF THE HOUR. SCA REMAINS UP
THROUGH THIS AFTERNOON. MIXING IMPROVES MORE THIS AFTERNOON...AND SHOWERS
AND SCATTERED THUNDERSTORMS WILL PRODUCE LOCALLY HEAVY RAINFALL
THAT CAN REDUCE VSBYS AND PERHAPS LOCALLY HIGHER WIND GUSTS.

EAST/SOUTHEAST WINDS WL CONTINUE TONIGHT THROUGH FRIDAY.
SHRA 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.

&&

.HYDROLOGY...
WE HAVE BEEN WAITING FOR A COUPLE DAYS NOW TO SEE WHERE THE PRIMARY
RAINBAND IS GOING TO SET UP. I THINK WE ARE STARTING TO SEE THE
ANSWER...AND IT APPEARS TO BE FARTHER EAST THAN ORIGINALLY PROJECTED
BY COMPUTER MODELS.

THIS HAD PRETTY SIGNIFICANT IMPLICATIONS ON THE RIVER FORECASTS
PRODUCED BY THE MIDDLE ATLANTIC RIVER FORECAST CENTER...WHICH ARE
NOW SHARPLY LOWER IN MANY AREAS.

ADDITIONAL RAINFALL WILL BE VERY LIMITED IN THE UPPER POTOMAC...
PERHAPS LESS THAN A QUARTER INCH. BUT TWO TO FOUR ADDITIONAL INCHES
OF RAINFALL...WITH ISOLATED HIGHER AMOUNTS...REMAINS POSSIBLE IN THE
EASTERN HALF OF THE FORECAST AREA. I STILL SEE SOME RISK OF UPSLOPE
PRECIP AS WELL...WHICH COULD ENHANCE AMOUNTS LOCALLY.

AT THIS TIME...ISSUED NO NEW FLOOD WARNINGS FOR THE RIVERS. ONLY PAW
PAW ON THE POTOMAC...AND A FEW OF THE SMALL TRIBUTARIES...HAVE
WARNINGS AT THIS TIME. SEVERAL RIVER FLOOD WATCHES REMAIN IN EFFECT.

&&

.TIDES/COASTAL FLOODING...
HAVE ADJUSTED THE COASTAL FLOOD HEADLINE SLIGHTLY. HAVE REPLACED
THE FIRST PART OF THE COASTAL FLOOD WATCH WITH A COASTAL FLOOD
ADVISORY FOR THE HIGH TIDE TONIGHT INTO THURSDAY MORNING.
ANOMALIES OF 1 TO 2 FEET ARE EXPECTED. HAVE KEPT WATCH IN EFFECT
FOR THE SUBSEQUENT HIGH TIDE CYCLE AS THERE IS STILL THE POTENTIAL
FOR MODERATE TIDAL FLOODING ESPECIALLY AT SENSITIVE LOCATIONS.
