AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC
244 PM EDT WED MAY 14 2014

.SYNOPSIS...
HIGH PRESSURE WILL REMAIN OFFSHORE THROUGH THE REST OF THE WEEK.
A COLD FRONT EXTENDING FROM THE GREAT LAKES TO THE GULF COAST
STATES WILL TRACK SLOWLY EAST...MOVING INTO THE MID ATLANTIC
STATES THURSDAY AND FRIDAY. HIGH PRESSURE IS EXPECTED TO RETURN TO
THE MID ATLANTIC THIS WEEKEND.

&&

.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
EASTERLY FLOW HAS MOVED INTO THE MID ATLANTIC RESULTING IN A 2.5K FT
STRATUS DECK ON THE COLD SIDE OF A BACK DOOR COLD FRONT THIS MORNING. A
BINARY RESULT OF SKY COVER HAS OCCURRED ACROSS THE REGION DUE TO THE
MARINE LAYER. LOCATIONS IN THE CENTRAL FOOTHILLS...ALONG RIDGE LINES
AND PARTS OF THE POTOMAC HIGHLANDS ARE GETTING FULL SUN THIS
MORNING. WEAK FLOW WITHIN THE MARINE LAYER AS WELL AS ON TOP OF THE
MARINE LAYER WILL LEAD TO A SLOW DISSIPATION FROM WEST TO EAST OF
STRATUS TODAY. THIS WILL LEAD TO TEMPS REACHING THE LOW 70S IN NE
MD TO THE UPPER 70S IN NOVA AND THE PANHANDLE OF WV. FCST SOUNDINGS
THAT HAD A HANDLE ON THE MARINE LAYER FROM THE 12Z IAD RAOB SHOWS
THE POTENTIAL FOR BREAKS IN THE CLOUDS THIS AFTERNOON WITH NE MD
INCLUDING BALTIMORE METRO BEING THE LAST TO BREAK BY LATE
AFTERNOON. OVERALL...NOT EXPECTING STRATUS DECK TO ERODE DURING
THE DAY FOR AREAS EAST OF THE BLUE RIDGE INCLUDING THE I-95
CORRIDOR AND PIEDMONT.

ELSEWHERE...FULL SUN WILL LEAD TO TEMPS REACHING THE 80S TODAY AND
PER THE 12Z RNK RAOB WHICH IS UPSTREAM... INSTABILITY OF UP TO 2000
J/KG IS POSSIBLE. SHOWERS AND THUNDERSTORMS ARE EXPECTED TO FORM DUE
TO TERRAIN CIRCULATIONS AS WELL AS ON THE DIFFERENTIAL HEATING
BOUNDARY OF THE MARINE LAYER. SOME STORMS WILL BE CAPABLE OF STRONG
UPDRAFTS AND THEREFORE DMG WINDS AND LARGE HAIL ARE POSSIBLE. SHEAR
PROFILES INCREASE IN MAGNITUDE FROM THE CENTRAL FOOTHILLS TO THE
POTOMAC HIGHLANDS AND THEREFORE A HIGHER CHANCE FOR SEVERE
THUNDERSTORMS ACROSS THE POTOMAC HIGHLANDS. 11Z HRRR SHOWS
CONVECTION STARTING AFTER 16Z TODAY. THE STORM MOTION WILL BRING
SHOWERS AND THUNDERSTORMS NORTH AND EAST BUT THE STABLE AIRMASS
WILL LIKELY CAUSE THUNDERSTORMS TO DISSAPTE.

PREVIOUS DISCUSSION...
ANY LEFTOVER CONVECTION THIS EVENING WILL DISSIPATE OVERNIGHT AND
A SOUTHEAST FLOW IS EXPECTED AHEAD OF AN APPROACHING COLD FRONT
AND BEHIND DEPARTING HIGH PRESSURE OFF THE NEW ENGLAND COAST. LOW
CLOUDS ALONG WITH AREAS OF FOG AND DRIZZLE ARE EXPECTED OVERNIGHT.

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH FRIDAY/...

...UPDATE...A FLASH FLOOD WATCH IS IN EFFECT FOR MOST COUNTIES IN
THE FORECAST AREA THURSDAY THROUGH FRIDAY...

PREVIOUS DISCUSSION...
A STRONG UPPER-LEVEL TROUGH WILL DIG OVER THE MIDWEST AND GULF
COAST STATES THURSDAY WHILE THE COLD FRONT ASSOCIATED WITH THIS
TROUGH SLOWLY TRACKS EAST TOWARD OUR AREA BY LATE IN THE DAY. THE
TROUGH AXIS WILL SWING TOWARD BEING NEGATIVELY TILTED...ALLOWING
FOR MORE HEIGHT FALLS WITHIN THE WARM SECTOR. THE FORCING ALONG
THE FRONT WILL BE QUITE STRONG DUE TO A STRONG PRESSURE GRADIENT
BETWEEN THE FRONT AND HIGH PRESSURE OVER THE ATLANTIC OCEAN. THE
STRONG FORCING WILL COMBINE WITH DEEP TROPICAL MOISTURE BEING
ADVECTED INTO THE AREA AHEAD OF THE BOUNDARY...TO CAUSE WIDESPREAD
SHOWERS WITH LOCALLY HEAVY RAINFALL AHEAD OF THE COLD FRONT. THIS
ACTIVITY IS EXPECTED TO OVERSPREAD THE POTOMAC HIGHLANDS THURSDAY
AFTERNOON. FURTHER EAST ACROSS THE WASHINGTON AND BALTIMORE
METROPOLITAN AREAS...A FEW SHOWERS AND THUNDERSTORMS ARE POSSIBLE
DURING THE AFTERNOON BUT THE WIDESPREAD PRECIPITATION MAY REMAIN
TO THE WEST DUE TO THE SLOW MOVEMENT OF THE COLD FRONT. DESPITE
PLENTY OF CLOUD COVER...FAVORABLE SHEAR PROFILES AND HIGH
DEWPOINTS SUGGEST THAT THERE IS A THREAT FOR SEVERE THUNDERSTORMS
THURSDAY AFTERNOON.

A SLOW BUT STEADY ARRIVAL OF THE MOISTURE PLUME EXPECTED LATE THU
EVE. EARLIER IN THE DAY...THE PARENT UPPER TROUGH WILL HAVE DIVED
DOWN WELL INTO THE LOWER MS VLY. THE HIGHLY AMPLIFIED TROUGH AXIS
WILL ESSENTIALLY SCOOP A DENSE SECTOR OF GULF MOISTURE OVER A
RELATIVELY THIN AXIS. THIS MOISTURE AXIS WILL BE JUST ON THE LEE
SIDE OF THE UPPER TROUGH...BUILDING AND DRIFTING NNE ACROSS THE SRN
APLCNS THU MRNG/AFTN.

HEADING INTO THE LATE EVE/NIGHTTIME HRS...THE UPPER VORT POWERING
THE TROUGH WILL BEGIN TO TILT NEGATIVELY WHICH IS AN INTENSIFICATION
PHASE FOR THE SYSTEM - MAXIMIZING THE AMOUNT OF QPF POSSIBLE W/ THE
SYSTEM. MOST MED RANGE MEMBERS GIVING THE WRN HALF OF OUR CWA A
PORTION OF THE BULLSEYE FOR POTENTIAL QPF - MAINLY DURING THE THU
LATE NIGHT AND EARLY MRNG HRS FRI. A FLASH FLOOD WATCH WILL LIKELY
BE NEEDED WITHIN THE NEXT FORECAST PERIOD OR SO...WHICH THE SOLID
CONSENSUS OF QPF DEPICTIONS. LOCALLY INTENSE RAINFALL AND EMBEDDED
CONVECTIVE ELEMENTS WILL CREATE THE POTENTIAL FOR AT LEAST A COUPLE
OF INCHES OF RAIN OVER THE SHEN VLY/APLCNS.

A SFC LOW PRES SYSTEM WILL DEVELOP OFF THE LEE SIDE OF THE HIGHER
TERRAIN AND STRENGTHEN AS IT EFFECTIVELY TRACKS RIGHT ACROSS OUR
CWA. THE TRACK WILL DETERMINE THE CONVECTIVE POTENTIAL FOR THE
AREA...THOUGH EMBEDDED ELEVATED CONVECTION AT VERY LEAST WILL BE
POSSIBLE ACROSS THE REGION. THE MODERATE TO HEAVY RAIN BATCHES WILL
CONTINUE TO MOVE EWD DURING THE PREDAWN HRS FRI OVER THE BLUE RIDGE
AND EAST. THE I-95 CORRIDOR WILL BE HIGHLIGHTED DURING THE
FIRST-HALF OF THE DAY FRI...W/ EMBEDDED AREAS OF HEAVY RAIN
SPREADING ACROSS THE AREA AND A STILL INTENSE LOW LEVEL JET HELPING
TO KEEP THE INTENSITY OF THE SYSTEM INTACT. A QUICK END TO THE
PRECIP LINE WILL ARRIVE TOWARD THE MID-LATE AFTN W/ ONLY A FEW
RESIDUAL SHOWERS OCCURRING IN THE BACK EDGE SUBSIDENCE REGION. THE
MOISTURE AXIS WILL DISSIPATE AS IT ARRIVES OVER DELMARVA AND MOVES
OFF THE COAST LATE FRI EVE.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
AN UPPER LOW DRIFTING DOWN FROM SOUTH OF THE HUDSON BAY AROUND WILL
ROTATE AROUND THE GREAT LAKES INTO THE COMING WEEKEND...KEEPING OUR
AREA QUITE COOL AND RELATIVELY DRY. THE "WEATHER" FROM THIS FEATURE
WILL MAKE IT FEEL MORE LIKE MARCH THAN MAY...EVEN THOUGH AVG TEMPS
FOR MID-MAY ARE IN THE M70S. A SLOW MOVING AND COLD UPPER LOW TAKING
A FEW DAYS TO EXIT THE NORTHEAST WILL KEEP US IN THIS PATTERN WELL
INTO NEXT WEEK. IT MAY BE SEVERAL MORE DAYS BEFORE WE GET ANYWHERE
CLOSE TO 80 DEG OR MORE...BASED ON THE PATTERN SETTING UP FOR NEXT
WEEK. THE HUDSON BAY LOW WILL SLOWLY DRIFT OFF THE NEW ENGLAND COAST
AS AN UPPER RIDGE BUILDS TO THE WEST.

&&

.AVIATION /19Z WEDNESDAY THROUGH MONDAY/...
IFR CONDITIONS ARE EXPECTED THROUGH MID-MORNING DUE TO LOW CLOUDS
ALONG WITH AREAS OF FOG AND DRIZZLE. CIGS SHOULD IMPROVE TO MVFR
LEVELS LATE THIS MORNING AND AFTERNOON...BUT MORE IFR/SUBIFR
CONDITIONS ARE EXPECTED LATE TONIGHT INTO EARLY THURSDAY.
CIGS/VSBYS SHOULD IMPROVE THURSDAY AFTERNOON.

A FEW SHOWERS AND THUNDERSTORMS ARE POSSIBLE THIS AFTERNOON AND
EVENING MAINLY FOR CHO AND MRB...AND AGAIN THURSDAY AFTERNOON FOR
ALL TERMINALS.

A COLD FRONT WILL CAUSE WIDESPREAD SHOWERS WITH LOCALLY HEAVY
RAINFALL AND A FEW THUNDERSTORMS THURSDAY NIGHT INTO FRIDAY.
CONDITIONS WILL IMPROVE LATER FRIDAY. HIGH PRESSURE WILL BUILD
OVERHEAD DURING THE WEEKEND.

A STRONG LOW PRESSURE SYSTEM WILL MOVE ACROSS THE REGION FROM
LATE THU INTO FRI. MAINLY PERIODS OF HEAVY RAIN WOULD BE THE
CONCERN...W/ BREEZY SFC WINDS BUT EVEN STRONGER LOW LEVEL FLOW - A
GOOD 30-50KT IN THE BOUNDARY LAYER OUT AHEAD OF THE SFC LOW LATE THU
INTO EARLY FRI. A COLD FRONT WILL PUSH THE PRECIP AND ANY EMBEDDED
TSTMS OFF THE COAST BY LATE FRI...W/ COOLER AND DRIER AIR BEING
USHERED IN FOR THE COMING WEEKEND.

&&

.MARINE...
AN EASTERLY FLOW THIS MORNING WILL TURN TO THE SOUTHEAST THIS
AFTERNOON AS HIGH PRESSURE MOVES OFF THE NEW ENGLAND COAST. THE
SOUTHEAST FLOW WILL CONTINUE THROUGH THURSDAY. THE PRESSURE
GRADIENT WILL INCREASE DURING THIS TIME AND A SMALL CRAFT ADVISORY
IS IN EFFECT FOR THURSDAY AFTERNOON. HOWEVER...WIND GUSTS MAY
APPROACH SCA CRITERIA TONIGHT THROUGH THURSDAY MORNING...BUT
GUSTS HAVE BEEN CAPPED AROUND 15 KNOTS FOR NOW DUE TO THE
RELATIVELY COOLER WATERS AND WEAKER PRESSURE GRADIENT.

SFC WINDS WILL INCREASE OUT OF THE S-SE THU AFTN/EVE AHEAD OF A SFC
LOW PRES SYSTEM. WIDESPREAD RAIN AND ISOLATED TSTMS WILL ARRIVE INTO
THE EARLY MRNG HRS FRI. WINDS WILL MAX-OUT IN THE UPPER SCA/LOW-END
GALE RANGES AS THE LOW PUSHES EAST AND MOVES OVER THE WATERS. WINDS
BEHIND THE SYSTEM WILL SUBSIDE WELL BELOW SCA CRIT HEADING INTO THE
WEEKEND...W/ ONLY A LIGHT W/NW BREEZE EXPECTED. THIS WILL ALSO LAST
INTO EARLY NEXT WEEK.

&&

.TIDES/COASTAL FLOODING...
TIDAL ANOMALIES HAVE INCREASED UP TO AROUND ONE-HALF FOOT ABOVE
NORMAL THIS MORNING DUE TO AN ONSHORE FLOW. THE ONSHORE FLOW
SHOULD REMAIN WEAK ENOUGH TO KEEP WATER LEVELS BELOW MINOR COASTAL
FLOODING THRESHOLDS. THE HIGH TIDE THIS AFTERNOON INTO THIS
EVENING WILL BE THE LOWER OF THE TWO...SO WATER LEVELS SHOULD
REMAIN BELOW MINOR FLOODING THRESHOLDS...DESPITE AN INCREASE IN
TIDAL ANOMALIES.

THE ONSHORE FLOW WILL CONTINUE TONIGHT THROUGH THURSDAY NIGHT AND
POSSIBLY INTO FRIDAY BEFORE TURNING OFFSHORE BEHIND A COLD FRONT
LATER FRIDAY. DESPITE THE ONSHORE FLOW REMAINING WEAK
TONIGHT...MINOR COASTAL FLOODING IS POSSIBLE WITH THE HIGH TIDE
CYCLE LATE TONIGHT INTO THURSDAY MORNING SINCE IT WILL BE THE
HIGHER OF THE TWO. THE ONSHORE FLOW WILL STRENGTHEN LATER THURSDAY
THROUGH THURSDAY NIGHT. MINOR FLOODING IS LIKELY NEAR HIGH TIDES
DURING THIS TIME. TIDAL ANOMALIES WILL GRADUALLY DECREASE FRIDAY.
