AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC
247 PM EDT TUE MAY 7 2013

.SYNOPSIS...
LOW PRESSURE WILL TRACK NORTHEAST INTO THE MIDDLE ATLANTIC
BY WEDNESDAY. THE LOW WILL SLOWLY PULL AWAY FROM THE REGION LATER
THURSDAY BUT UNTIL THEN...UNSETTLED CONDITIONS ARE EXPECTED TO
PERSIST. A COLD FRONT WILL APPROACH LATE IN THE WEEK INTO THE
WEEKEND.

&&

.NEAR TERM /THROUGH TONIGHT/...
UPPER LOW OVER THE CAROLINAS WILL TRACK NORTHEAST INTO/THROUGH THE
MID-ATLANTIC TONIGHT/WEDNESDAY...AS SURFACE HIGH PRESSURE REMAINS
ANCHORED OVER THE NORTH ATLANTIC.

MOIST EASTERLY FLOW HAS BEEN WELL ESTABLISHED ACROSS THE
MID-ATLANTIC. THIS COMBINED WITH UPPER DIVERGENCE TO THE NORTH OF
THE LOW AND SOME NEAR SURFACE CONVERGENCE HAS LEAD TO WIDESPREAD
SHOWERS ACROSS MUCH OF THE CWA TODAY.

PER NAM/HRRR GUIDANCE...MAIN AREA OF SHOWERS TILTS TO THE NORTHWEST
THROUGH THE LATE AFTERNOON AND EVENING WITH ADDITIONAL SHOWER
DEVELOPMENT OCCURRING TO THE SOUTHEAST. THIS AREA OF ADDITIONAL
SHOWER DEVELOPMENT MAY BE ACCOMPANIED BY ISOLATED THUNDERSTORMS INTO
THE EVENING AS LATEST RADAR TRENDS HAVE INDICATED. WHILE THE BULK OF
THE COLD AIR NEAR THE LOW WILL RESIDE SOUTHWEST OF THE CWA...THE
FRINGE OF THIS MAY EXTEND INTO THE VIRGINIA PIEDMONT/LOWER SOUTHERN
MARYLAND AND ADJACENT WATERS. THIS IS WHERE NAM HAS PORTRAYED WEAK
INSTABILITY AND THUS ANY THUNDERSTORMS HAVE THE POTENTIAL TO PRODUCE
SOME HAIL AND STRONG GUSTY WINDS. THIS POTENTIAL LOOKS TO WANE THIS
EVENING EVEN THOUGH SHOWERS ARE EXPECTED TO CONTINUE THROUGH THE
NIGHT AS THE UPPER LOW MOVES CLOSER TO THE AREA.

GIVEN CLOUDS/SHOWERS...TEMPERATURES ARE EXPECTED TO FALL ONLY A
DEGREES OVERNIGHT AND HAVE FAVORED ABOVE MOS VALUES.

&&

.SHORT TERM /WEDNESDAY/...
FOR WEDNESDAY...UPPER LOW WILL RESIDE ACROSS THE MID-ATLANTIC. THERE
WILL BE SHOWERS ACROSS THE CWA ALTHOUGH ITS DIFFICULT TO PINPOINT
THE EXACT LOCATION OF THEM THROUGHOUT THE DAY. HAVE KEPT LIKELY POPS
IN DURING THE DAY...BUT FIGURE THAT AS WE GET CLOSER MORE DETAILS TO
TIMING WILL ABLE TO BE ADDED TO THE FORECAST.

MAXIMA SHOULD BE ABLE TO CREEP UPWARD SOME OVER TODAY...BUT FEEL IT
PRUDENT TO KEEP BELOW MOS ON WEDNESDAY GIVEN EXTENSIVE CLOUD COVER
AND LIKELIHOOD OF SHOWERS.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH TUESDAY/...
AS LONG AS IT MAY SEEM FOR THIS UPPER LOW TO CROSS OUR AREA - MON
THRU THU - THIS FEATURE HAS BEEN ACTUALLY MOVING AT A STEADY CLIP
COMPARED TO IT'S BEGINNINGS BACK ACROSS THE PLAINS LAST WEEK. THIS
LOW PRESSURE SYSTEM HAS BEEN SO EXTENSIVE THAT IT HAS TAKEN MUCH
OF THIS WEEK TO CLEAR THE AREA. WED NIGHT INTO EARLY THU...THE
LAST BATCHES OF SHOWERS DIRECTLY ASSOCIATED W/ THE UPPER LOW WILL
BE SLIDING OFF THE COAST AS THE LOW ITSELF MOVES TOWARD NEW
ENGLAND. A DEEPENING UPPER WAVE BACK ACROSS THE NRN PLAINS WILL
HELP TO PUSH THE LOW OFF TO THE NE AT A FASTER CLIP ON THU.

THE AIRMASS THAT LIES IN FRONT OF THE APPROACHING UPPER WAVE FROM
THE NRN PLAINS HOWEVER WILL STAY IN PLACE ACROSS THE ERN SEABOARD
FRI AND SAT...FINALLY PUSHED OFF THE COAST LATE SUN. UNTIL
THEN...DIURNAL HEATING WILL ALLOW FOR AFTN SHOWER/TSTM DEVELOP.
THOUGH THE AREAL EXTENT MAY BE FAIRLY WIDESPREAD...INSTABILITY WILL
BE MARGINAL. THU AND FRI WILL SEE TEMPS CLIMBING BACK ABOVE
AVERAGE...WELL INTO THE 70S FOR THU AFTN AND L80S ON FRI AFTN. THIS
WILL AIDE IN DEVELOPING SOME AFTN/EVE INSTABILITY BUT THE DEWPOINTS
WILL STILL BE A BIT DRIER IN THE LOW LEVELS THAN WOULD BE NEEDED
FOR MORE WIDESPREAD/INTENSE CONVECTION.

SAT WILL BE A BIT BETTER IN TERMS OF THESE PARAMETERS...W/ SLIGHTLY
HIGHER DEWPOINTS IN THE L60S. PLENTY OF CLOUDS WILL BE PRESENT
DURING THE LATTER HALF OF THE WEEK...W/ ONLY INTERMITTENT BREAKS OF
SUN OR CLEARING. THE TAIL-END OF THE CURRENT NAM RUN AND THE LATEST
GFS GUIDANCE SHOW A WEAK SFC LOW SLIDING ACROSS THE NY/PA AREA ON
FRI...BRINGING A WEAK LEE SFC TROUGH OVER THE AREA LATE FRI. THIS
MAY HELP TO DEVELOP SOME SHOWER/ISLD TSTMS. A MORE PRONOUNCED SFC
BOUNDARY IS EXPECTED TO APPROACH ON SAT...MOVING ACROSS THE REGION
DURING THE DAYTIME HRS AND HELP DEVELOP MORE WIDESPREAD AND MORE
LOCALLY INTENSE CONVECTION.

THIS SOLUTION FROM THE GFS IS STILL IN SOME DIVERGENCE TO THE EURO'S
TAKE OF A MORE SOUTHERN AND SLOW UPPER LOW PASSAGE OVER S CNTRL
CANADA THIS WEEKEND. THE INTENSITY AND MOVEMENT OF THIS FEATURE WILL
DETERMINE HOW POTENT THE COLD FRONT IS FOR OUR REGION AND WHEN IT
WILL CROSS THE AREA. DIFFERING FROM THIS TIME YESTERDAY...THE FRONT
IS NOW DEPICTED TO ARRIVE EARLY SUN...W/ THE BULK OF CONVECTION AND
GENERAL RAIN CHANCES DURING THE DAYTIME/EVE HRS SAT. WHILE THE FRONT
IS APPROACHING...BOTH MODELS START TO DEVELOP A LEE SFC LOW PRESSURE
SYSTEM OFF THE NRN VA BLUE RIDGE SAT AFTN...CREATING A KINK IN THE
LARGER COLD FRONT THAT MAKES FOR A LOCALLY MORE POTENT FEATURE
ACROSS OUR REGION.

&&

.AVIATION /19Z TUESDAY THROUGH SUNDAY/...
ONE CHALLENGE FOR THE 18Z TAF CYCLE WAS WHETHER PREVAILING IFR
CONDITIONS WOULD IMPROVE TO MVFR OR NOT. BEST CHANCE OF THIS
HAPPENING LOOKS TO BE CHO TO DCA...BUT THERE IS AN OUTSIDE CHANCE OF
THIS OCCURRING AT BWI AS WELL. ANOTHER CHALLENGE WAS THE POTENTIAL
FOR THUNDER. HAVE FOCUSED ON PREVAILING SHOWERS AS WX TYPE IN
TAFS...BUT ACKNOWLEDGE THE POSSIBILITY OF ISOLATED THUNDERSTORMS
INTO THIS EVENING AT CHO. FEELING IS THAT ANY THUNDERSTORMS WOULD
REMAIN SOUTH OF IAD-DCA...BUT PERHAPS NOT THAT FAR AWAY AND WILL
NEED TO BE MONITORED.

IF IMPROVEMENT IN FLIGHT RESTRICTIONS DOES OCCUR THIS
AFTERNOON...ITS EXPECTED TO BE BRIEF AND A RETURN TO IFR/LIFR
CONDITIONS IS LIKELY TONIGHT AND LASTING INTO WEDNESDAY MORNING.
CONSENSUS IS FOR VFR TO RETURN BY WEDNESDAY AFTERNOON...ALTHOUGH
WITH SHOWERS AROUND AT LEAST TEMPORARY MVFR CONDITIONS WILL BE
POSSIBLE.

AS THE UPPER LOW FINALLY EXITS THE REGION EARLY THU...SOME RESIDUAL
SHOWER ACTIVITY WILL CONTINUE ACROSS THE AREA - W/ POSSIBLE
REDEVELOPMENT ON THU AFTN/EVE AS WELL. SOME LINGERING LOW-END VFR
CIGS WILL STICK AROUND ON THU...BUT CONDITIONS SHOULD IMPROVE INTO
FRI. THE LOSS OF DAYTIME HEATING WILL QUIET DOWN THE AREA THU NIGHT
INTO EARLY FRI. TWO CONSECUTIVE DAYS OF FRONTAL BOUNDARIES CROSSING
THE AREA FRI AND SAT...MEETING THE FAIRLY MOIST AND MARGINALLY
UNSTABLE AIRMASS WILL HELP CREATE MORE SHOWERS AND A FEW TSTMS EACH
DAY. A SHARP COLD FRONT WILL USHER IN DRIER CONDITIONS LATE SAT
INTO SUN MRNG...PUSHING THIS ACTIVITY OFF THE COAST AND BRINGING
DRY AIR INTO THE AREA FOR EARLY NEXT WEEK.

&&

.MARINE...
EASTERLY FLOW HAS BEEN GUSTY AT TIMES TODAY...ALTHOUGH THERE HAVE
ALSO BEEN LULL PERIODS. SHOWERS MOVING ACROSS THE WATERS MAY BE
HAVING SOME IMPACT. ANY ISOLATED THUNDERSTORMS ACROSS THE LOWER
TIDAL POTOMAC/LOWER MD BAY COULD HAVE HAIL AND GUSTIER WINDS AS
WELL. BUT TREND WILL BE FOR DIMINISHING WINDS OVERNIGHT AND GUIDANCE
KEEPS WINDS BELOW SCA THRESHOLDS ON WEDNESDAY.

WITH THE UPPER LOW DRIFTING OVERHEAD DURING THE MIDDLE OF THIS
WEEK...WINDS WILL BE TEMPERED TO A LIGHT BREEZE THRU THE END OF THE
WORK WEEK. AS THE UPPER LOW MOVES TOWARD NEW ENGLAND THU INTO
FRI...ANOTHER STRONG COLD/DRY AIR PUSH WILL MAKE ITS WAY DOWN ACROSS
THE UPPER MIDWEST FROM A CANADIAN LOW PRESSURE SYSTEM. AS THE
ASSOCIATED COLD FRONT PUSHES TOWARD THE AREA THIS WEEKEND...THE SFC
PRES GRADIENT WILL INCREASE AND SO WILL WINDS ON SAT AFTN AHEAD OF
THE FRONT. THE FRONT IS EXPECTED TO MOVE ACROSS THE WATERS BY EARLY
SUN...CLEARING OUT RAIN AND TSTM ACTIVITY AND KEEPING A LIGHT BUT
STEADY BREEZE OVER THE AREA INTO EARLY NEXT WEEK.

&&

.TIDES/COASTAL FLOODING...
DEPARTURES CONTINUE TO AVERAGE 1/2 TO 1 FT ABOVE ASTRONOMICAL
PREDICTION THIS AFTERNOON. LITTLE CHANGE IS EXPECTED THROUGH THE
HIGH CYCLE THIS AFTERNOON/EARLY EVENING...AND EVEN A 1 FT
ANOMALY WOULD KEEP LEVELS BELOW MINOR THRESHOLDS FOR THE HIGH TIDE
CYCLE WHICH IS THE LOWER OF THE NEXT TWO CYCLES. WILL HAVE TO BE MORE
CONCERNED ABOUT THE OVERNIGHT/WEDNESDAY MORNING CYCLE ESPECIALLY IF
ANOMALIES CREEP UP A LITTLE BIT BETWEEN NOW AND THEN.
