AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC
1119 AM EDT WED APR 30 2014

.SYNOPSIS...
A WARM FRONT WILL GRADUALLY LIFT TO THE NORTH TODAY. A COLD FRONT
WILL THEN MOVE ACROSS THE AREA LATE TONIGHT INTO THURSDAY MORNING.
HIGH PRESSURE BUILDS IN FOR FRIDAY. A WEAK COLD FRONT MAY MOVE
THROUGH SATURDAY.

&&

.NEAR TERM /THROUGH TONIGHT/...
CUTOFF LOW PRESSURE OVER THE NORTHERN PLAINS WILL CONTINUE TO
SLOWLY DRIFT INTO THE WESTERN GREAT LAKES THROUGH TONIGHT. THE
WARM FRONT ASSOCIATED WITH THE LOW DIPS SOUTHEAST INTO WESTERN
NORTH CAROLINA THIS MORNING. THE BOUNDARY EXTENDS NORTHEAST INTO
SOUTHERN MARYLAND. THE COLD FRONT ASSOCIATED WITH THE LOW EXTENDS
SOUTH INTO THE TENNESSEE VALLEY THIS MORNING.

TROPICAL AIR CONTINUES TO OVERRUN THE SURFACE COOL AIR IN
PLACE...RESULTING IN RAIN THIS MORNING. THE HEAVIEST RAIN WILL BE
NEAR AND EAST OF THE BLUE RIDGE WHERE THE MOISTURE IS DEEPEST AND
ELEVATED INSTABILITY IS CAUSING CONVECTION. HEAVY RAINFALL WITH
RAINFALL RATES OVER ONE INCH PER HOUR ARE EXPECTED ACROSS THESE
AREAS DURING THIS TIME.

THE WARM FRONT WILL CONTINUE TO SLOWLY PUSH NORTH AND WEST INTO
OUR AREA THIS AFTERNOON. THE MARINE LAYER MAY HOLD ON A BIT LONGER
THAN WHAT GUIDANCE IS SUGGESTING DUE TO THE FACT THAT THE MARINE
LAYER IS DEEPER ON THE 12Z KIAD RAOB COMPARED TO WHAT THE MODELS
WERE FORECASTING FOR THAT TIME. HAVING THAT BEEN SAID...THE
BOUNDARY SHOULD STILL LIFT NORTH THROUGH MOST OF OUR AREA THIS
AFTERNOON...PUTTING THE WARM SECTOR OVERHEAD. THERE SHOULD BE
ENOUGH DESTABALIZATION IN THE WARM SECTOR FOR AROUND 300-600 J/KG
OF MLCAPE TO DEVELOP...DESPITE THE CLOUD COVER. SHEAR PROFILES
REMAIN QUITE FAVORABLE FOR SEVERE THUNDERSTORMS WITH THE PRIMARY
THREATS BEING DAMAGING WIND GUSTS AND ISOLATED TORNADOES. THE MAIN
UNCERTAINTY IS WHETHER OR NOT STORMS CAN GET ROOTED WITHIN THE
BOUNDARY LAYER...AND THAT IS LIKELY IN THE WARM SECTOR THIS
AFTERNOON AND EVENING. SINCE THE MARINE AIR MAY TAKE A BIT LONGER
TO MIX OUT...THE BEST CHANCE FOR SEVERE THUNDERSTORMS WILL BE
LATER THIS AFTERNOON AND TONIGHT. THE STABLE LAYER MAY BE A BIT
STRONGER NEAR THE MASON-DIXON LINE TOWARD THE WESTERN SHORE OF THE
MARYLAND CHESAPEAKE BAY...SO UNCERTAINTY FOR SEVERE WEATHER ACROSS
THESE AREAS IS A BIT HIGHER.

PWATS WILL BE NEAR RECORD LEVELS THIS AFTERNOON...SO SHOWERS AND
THUNDERSTORMS WILL PRODUCE HEAVY RAINFALL. SHOWERS AND
THUNDERSTORMS HAVE THE POTENTIAL TO TRAIN OVER THE SAME AREAS AS
WELL...CAUSING VERY HEAVY AMOUNTS OF RAIN IN A SHORT PERIOD OF
TIME. THE FLASH FLOOD WARNING REMAINS IN EFFECT FOR THE AREA.

THE COLD FRONT ASSOCIATED WITH THE LOW WILL MOVE INTO THE POTOMAC
HIGHLANDS THIS EVENING BEFORE APPROACHING THE I-95 CORRIDOR
OVERNIGHT. MORE SHOWERS AND THUNDERSTORMS ARE EXPECTED ALONG WITH
HEAVY RAIN AND THE THREAT FOR SEVERE WEATHER. THE BEST CHANCE FOR
HEAVY SHOWERS AND THUNDERSTORMS WILL BE THIS EVENING WEST OF THE
BLUE RIDGE MOUNTAINS...AND THROUGH TONIGHT EAST OF THE BLUE RIDGE
MOUNTAINS.

&&

.SHORT TERM /THURSDAY THROUGH FRIDAY/...
COLD FRONT WILL MOVE EAST OF THE CWA AND OFFSHORE THURSDAY MORNING.
MUCH OF THE THUNDERSTORM ACTIVITY WILL LIKELY HAVE ALSO PUSHED TO
THE EAST BY 12Z...BUT THERE MAY BE SOME LINGERING SHOWERS NEAR THE
BOUNDARY TO START THE DAY. WIND SHIFT BEHIND THE FRONT WILL BEGIN TO
BRING DRIER AIR IN FOR THE AFTERNOON AND IT/S POSSIBLE THAT CLOUDS
BREAK FOR SOME SUNSHINE IN THE AFTERNOON. BOTH DOWNSLOPING WIND AND
SOME SUNSHINE WILL CONTRIBUTE TO A WARM DAY WITH MAXIMA LIKELY WELL
INTO THE 70S /EXCEPT FOR THE HIGHER ELEVATIONS/RIDGES/.

SOMEWHAT COOLER PUSH COMES IN THURSDAY NIGHT INTO FRIDAY...ALTHOUGH
AIR MASS ISN/T REALLY ALL THAT COOL AND TEMPERATURES ARE EXPECTED TO
BE NEAR CLIMO TO END THE WEEK.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
A COUPLE OF WEAK SHORTWAVES/COLD FRONTS LOOK TO SWING THROUGH
SATURDAY AND SUNDAY...BUT GIVEN RELATIVELY DRY AIR IN PLACE LITTLE
IMPACT IS EXPECTED. RAIN CHANCES WILL PRIMARILY BE OVER THE
HIGHLANDS...WITH PERIODS OF CLOUDS AS THE SHORTWAVES MOVE BY AND
TEMPERATURES HELD AROUND CLIMO.

WEAK HIGH PRESSURE WILL BUILD IN FROM THE NORTH EARLY NEXT WEEK WITH
A CONTINUATION OF NEAR AVERAGE TEMPERATURES.

&&

.AVIATION /15Z WEDNESDAY THROUGH SUNDAY/...
IFR CONDITIONS WILL CONTINUE INTO THIS AFTERNOON ALONG WITH
LOCALLY HEAVY SHOWERS AND THUNDERSTORMS. MVFR/IFR CONDITIONS ARE
EXPECTED THIS AFTERNOON AND TONIGHT ALONG WITH MORE SHOWERS AND
THUNDERSTORMS AHEAD OF A COLD FRONT. SEVERE THUNDERSTORMS ARE
POSSIBLE DURING THIS TIME...WITH LOCALLY DAMAGING WIND GUSTS AND
ISOLATED TORNADOES BEING THE PRIMARY THREATS. LOW-LEVEL WIND SHEAR
IS EXPECTED INTO EARLY THIS AFTERNOON WITH SOUTH-SOUTHEAST WINDS
AROUND 40 TO 45 KNOTS JUST A COUPLE THOUSAND FEET FROM THE
SURFACE. THE GUSTY WINDS WILL REMAIN ALOFT THROUGH MOST OF
TONIGHT...BUT SURFACE WINDS WILL ALSO BECOME SOUTHEAST SO LOW-
LEVEL WIND SHEAR REMAINS OUT OF THE TAFS DURING THIS TIME...EXCEPT
FOR KMRB WHERE THE MARINE LAYER MAY TAKE LONGER TO MIX OUT.

MVFR/IFR CONDITIONS MAY LINGER THROUGH 12Z-15Z THURSDAY...OTHERWISE
AS DRIER AIR MOVES IN BEHIND A COLD FRONT EXPECT IMPROVING
CONDITIONS FOR THE BALANCE OF THE DAY WITH NORTHWEST WINDS 10-15 KT.

NO SIGNIFICANT WEATHER IS EXPECTED FRIDAY INTO THE BULK OF THE
WEEKEND.

&&

.MARINE...
A GALE WARNING IS IN EFFECT FOR THE MARYLAND CHESAPEAKE BAY FROM
SANDY POINT TO SMITH POINT...AND FOR THE TIDAL POTOMAC RIVER FROM
COBB ISLAND TO SMITH POINT. A SMALL CRAFT ADVISORY IS IN EFFECT
FOR THE REST OF THE WATERS THROUGH TONIGHT.

A WARM FRONT WILL PASS THROUGH THE WATERS THIS AFTERNOON. EAST-
NORTHEAST WINDS AHEAD OF THE BOUNDARY WILL SHIFT TO THE SOUTH-
SOUTHEAST BEHIND IT. SHOWERS AND THUNDERSTORMS ARE EXPECTED
THROUGH TONIGHT...WITH LOCALLY HEAVY RAIN EXPECTED. SEVERE
THUNDERSTORMS ARE POSSIBLE THIS AFTERNOON AND TONIGHT WITH LOCALLY
DAMAGING WIND GUSTS AND ISOLATED WATERSPOUTS BEING THE PRIMARY
THREATS.

AS WINDS TURN TO THE NORTHWEST BEHIND A COLD FRONT THURSDAY
MORNING...SCA CONDITIONS MAY OCCUR OVER A PORTION OF THE
WATERS...PARTICULARLY THE LOWER TIDAL POTOMAC AND DOWN THE MAIN
CHANNEL OF THE CHESAPEAKE BAY. WILL HAVE TO WATCH FRIDAY AFTERNOON
FOR MARGINAL SCA CONDITIONS AS WELL...OTHERWISE AT THIS TIME WINDS
LOOK TO BE BELOW SCA THRESHOLDS INTO THE WEEKEND.

&&

.HYDROLOGY...
WAVES OF TROPICAL SHOWERS/TSTMS CONTINUE TO FUNNEL ACROSS THE AREA.
AFTER A SVRL HR RESPITE...PCPN FILLING BACK IN ATTM. ON AVG...RAFL
TTLS THRU 13 UTC UNDER ARE ESTIMATED TO BE BETWEEN 2 AND 3 INCHES
BASED ON GROUND REPORTS AND THE RADAR ESTIMATE.

WARM AND MOIST AIR CONTINUE TO MOVE INTO THE AREA. THE 12Z KIAD
RAOB SHOWS A 1.60 PWAT...WHICH IS WELL OVER TWO STANDARD
DEVIATIONS ABOVE CLIMO.  HIRES MODELS AND THE LATEST OPERATIONAL
GFS/NAM SHOW THE POTENTIAL FOR ADDTL WIDESPREAD 2-4 INCHES WITH
THE LEAST EXPECTED WEST OF THE BLUE RIDGE AND THE MOST SOMEWHERE
BETWEEN THE BLUE RIDGE AND I-95 CORRIDOR.

FLASH FLOOD WATCH REMAINS IN EFFECT AREA WIDE...AND RIVER FLOOD
WATCHES ARE IN EFFECT AT EIGHT FORECAST POINTS. IN TERMS OF FLASH
FLOODING...SHRA/TSRA PAST 24 HRS SETTING THE STAGE FOR A LKLY ACTIVE
DAY-EVNG AHD. NUMEROUS RIVER FLOOD WARNINGS ARE IN EFFECT AND A
RIVER FLOOD WATCH REMAINS IN EFFECT FOR THE SHENANDOAH AND POTOMAC
RIVER BASINS. CONTINUE TO MONITOR THE LATEST
FORECASTS...DISCUSSIONS...AND POTENTIAL WARNINGS.

&&

.TIDES/COASTAL FLOODING...
A COASTAL FLOOD WARNING CONTINUES UNTIL MIDNIGHT FOR THE WESTERN
SHORE OF THE CHEASAPEAKE BAY FROM SOUTHERN BALTIMORE TO ST MARYS
COUNTIES...AND ALSO FOR WASHINGTON DC ALONG THE UPPER TIDAL
POTOMAC RIVER. A COASTAL FLOOD ADVISORY IS IN EFFECT FOR THE REST
OF THE TIDAL POTOMAC RIVER. TIDAL ANOMALIES WILL CONTINUE TO
INCREASE THIS AFTERNOON AS THE FLOW TURNS TOWARD THE SOUTHEAST.

THE MAX ASTRONOMICAL HIGH TIDE WILL BE THURSDAY MORNING...SO THE
HIGHEST TIDES MAY OCCUR DURING THIS TIME. HOWEVER...THE OFFSHORE
FLOW WILL BE ARRIVING AROUND THE SAME TIME...WHICH MAY CAUSE
ANOMALIES TO START DROPPING DEPENDING ON EXACTLY WHEN IT ARRIVES.
DUE TO THE UNCERTAINTY...A COASTAL FLOOD WATCH IS IN EFFECT FOR
THE WESTERN SHORE OF THE MARYLAND CHESAPEAKE BAY AND THE UPPER
TIDAL POTOMAC RIVER BY WASHINGTON DC. A COASTAL FLOOD ADVISORY IS
IN EFFECT FOR THE REST OF THE TIDAL POTOMAC RIVER DURING THIS
TIME.

FRESHWATER FROM HEAVY RAINFALL WILL DRAIN THROUGH THE RIVER SYSTEM
AND REACH WASHINGTON DC SOMETIME FRI...RESULTING IN ADDTL
FLOODING FROM FRESHWATER SOURCES. MODERATE COASTAL FLOODING IS
POSSIBLE FOR THE UPPER TIDAL POTOMAC RIVER AROUND WASHINGTON DC.
