AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC
922 PM EDT MON MAY 12 2014
.SYNOPSIS...
HIGH PRESSURE WILL REMAIN PARKED OFFSHORE THROUGH THE REST OF THE
WEEK. A BACKDOOR COLD FRONT WILL DRIFT SOUTHWESTWARD INTO THE
REGION TUESDAY NIGHT BEFORE DISSIPATING OVER THE AREA ON WEDNESDAY.
A STRONGER COLD FRONT WILL SLOWLY APPROACH FROM THE WEST LATE IN
THE WEEK. HIGH PRESSURE IS EXPECTED TO RETURN TO THE MID ATLANTIC
STATES THIS WEEKEND.
&&
.NEAR TERM /THROUGH TUESDAY/...
LATE DAY CNVCTN WANING UPON NIGHTFALL. A ROUND PASSED THRU LWX
PRIOR TO LAUNCH...AND THAT SFC INVSN NOTED IN RAOB. THERE/S ALSO A
WK CAP ARND H5. WHEN NOCTURNAL EFFECTS ARE ADDED...DO NOT XPCT
MUCH PCPN OVNGT-- IF ANY. WL CONT A DRY FCST FOR THE OVNGT HRS.
HWVR...WET GRND/DEWPTS LWR-MID 60S/LTL WND SHUD PROVIDE AN
ENVIRONMENT FVRBL FOR PATCHY FOG FORMATION. MIN-T FCST MATCH
DEWPTS ATTM. ANTICIPATE TEMP CHGS TO BE MINIMAL.
IN THE SYNOPTIC SCALE...WE ARE ON THE NORTHERN PERIPHERY OF A
RIDGE OVER THE WESTERN ATLANTIC AND SOUTHEAST STATES. THERE/S ALSO
A BACKDOOR COLD FRONT FROM THE GREAT LAKES EAST THROUGH NEW YORK
STATE/NEW ENGLAND. WE ARE FORECAST TO REMAIN ON THE NORTHERN
PERIPHERY OF THE RIDGE THROUGH TUESDAY AND MODELS SUGGEST THE
BACKDOOR FRONT SLIPS SOUTHWARD POSSIBLY MAKING IT INTO NORTH
CENTRAL MARYLAND BY TUESDAY AFTERNOON.
ATMOSPHERE WILL BE MORE MOIST AND UNSTABLE BY TUESDAY AFTERNOON
SO WITH OR WITHOUT MORNING CONVECTION EXPECT SCATTERED
THUNDERSTORM DEVELOPMENT FOR THE AFTERNOON.
THERE IS A DISPARITY AMONG GUIDANCE FOR MAX T ON TUESDAY AND
THERE IS SOME UNCERTAINTY DUE TO CLOUD COVER. LEANED A LITTLE MORE
TOWARD THE WARMER SOLUTION AS AT LEAST SOME BREAKS ARE EXPECTED.
&&
.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/...
RIDGE AXIS ASSOCIATED WITH A FAIRLY AMPLIFIED UPPER RIDGE WILL
PROGRESS EASTWARD ALONG THE ERN SEABOARD TUE NGT AND OFFSHORE WED.
MODELS CONTINUE TO SHOW SFC HIPRES CENTERED TO THE EAST OF THE GULF
OF MAINE BUILDING SOUTHWESTWARD DOWN TOWARD THE MID-ATLANTIC STATES.
LEADING EDGE OF COOLER MARINE AIR DEPICTED AS A BACKDOOR COLD FRONT
THAT WILL LIKELY MOVE INLAND FROM THE CHSPK BAY. THIS SETUP FOR TUE
NGT AND WED IS SETTING UP TO BE VERY SIMILAR TO ONE FROM LAST WEEK
WHEN LOW CLOUDS/ FOG/PATCHY DRIZZLE DEVELOPED ON THE COOL SIDE OF
THE BOUNDARY THU NGT AND LINGERED INTO FRI. HIGHS LAST FRI WERE ONLY
NEAR 70F IN NORTH-CENTRAL MD AND UPPER 80S IN CENTRAL VA. MAX TEMP
FCST FOR WED ACCORDINGLY VERY SIMILAR. WEAK CONVERGENCE ALONG THE
REMNANT BACKDOOR MAY PROVIDE A FOCUS FOR CONVECTION ON WED OVER THE
MTS. THUNDERSTORMS ALSO POSSIBLE ON THE WARM SIDE OF THE BOUNDARY...
WHERE THE 12Z NAM/GFS PROG MLCAPE VALUES BETWEEN 1000-1500 J/KG
DURING THE AFTN. A PULSE SEVERE TSTM CANNOT BE RULED OUT GIVEN
FULL HEATING/DESTABILIZATION OCCURS. HOWEVER...STORM ORGANIZATION
AND SEVERE THREAT WILL BE LIMITED BY A WEAK WIND FIELD AND
MARGINAL SHEAR PARAMETERS.
ERN SEABOARD WILL BE POSITIONED IN CORRIDOR OF TROPOSPHERIC-DEEP SLY
FLOW AHEAD OF AN AMPLIFIED UPPER TROUGH OVER THE CENTRAL CONUS AND A
DOWNSTREAM RIDGE OFF THE EAST COAST. THE STEERING FLOW WILL BE
ORIENTED NEARLY PARALLEL TO A COLD FRONT...FAVORING THE BOUNDARY TO
BECOME STATIONARY TO THE WEST OF APPALACHIANS. THE LATEST 12Z
GUIDANCE HAS SLOWED DOWN EASTWARD PROGRESSION OF THIS SYSTEM...WHICH
WOULD KEEP THE BEST LIFT WITH THE FRONT AND WIDESPREAD HEAVY
RAINFALL TO THE WEST OF THE CWA DURING THE DAY THU. HAVE DECREASED
POPS CONSIDERABLY FROM PREV FCST...PARTICULARLY TO THE EAST OF THE
BLUE RIDGE WHERE SYNOPTIC LIFT REMAINS FARTHER UPSTREAM.
&&
.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
SOUTHERN VORTICITY MAX IN LONG WAVE TROUGH BECOMES MORE ELONGATED
WITH GRADIENT ALOFT AND HAS RESULTED IN SLOWER TIMING FOR THE COLD
FROPA. GFS/ECMWF NOW IN REASONABLE AGREEMENT WITH TIMING OF HEAVIEST
PRECIP FOR OVERNIGHT THURSDAY INTO EARLY FRIDAY. STRONG CONVERGENCE
ALONG LOW LEVEL THERMAL GRADIENT WITH 50+KT LLJ WILL PROVIDE FOCUSED
LIFT WHILE VORT MAX ALOFT MOVES OVERHEAD AND PROVIDES SYNOPTIC LIFT
THURSDAY NIGHT INTO FRIDAY. FORECAST SOUNDINGS STILL SHOWING DEEP
SATURATION WITH THIN CAPE PROFILES AND DEEP WARM CLOUD
LAYERS...WHICH SUGGESTS THAT HEAVY RAIN PROCESSES MAY BE FAVORABLE
SINCE UPDRAFTS WILL NOT BE PARTICULARLY STRONG. LONG SOUTHERLY FETCH
WILL DRAW IN AMPLE MOISTURE FROM THE CARIBBEAN WITH AN AXIS OF PWATS
INCREASING TO AROUND 1.75 INCHES AHEAD OF THE FRONT. LOOKS TO BE AN
UNDER CUTTING FRONT WITH CAA IN THE LOW LEVELS FIRST AS ACTUALLY
SURFACE WIND SHIFT OCCURS ON FRIDAY. THIS BRINGS AN END TO THE
PRECIP FROM WEST TO EAST AS THE DRY WEDGE INTRUDES FRIDAY.
COLD POOL ALOFT THEN PUSHES IN FOR SATURDAY...WITH SHOWERS
POSSIBLE DUE TO DIURNAL INSTABILITY AND VORT MAX ALOFT. COOLER
AIRMASS WITH TROUGH ALOFT WILL CONTINUE THROUGH SUNDAY AND
INSTABILITY SHOWERS LOOK POSSIBLE ONCE AGAIN.
&&
.AVIATION /01Z TUESDAY THROUGH SATURDAY/...
THREAT FOR SHRA/TSRA AT TERMINALS JUST ABT OVER. WET GRND/HUMID
AIR/LTL WND WL PROVIDE AN ATM WHERE FOG FORMATION FVRBL. AM
FOCUSING ON CLIMO FVRD SITES...CHO/MRB...AND BRIEFLY AT IAD. ALL
RESTRICTIONS WUD BE AFTR MIDNGT...AND BEGIN LIFTING ARND DAWN.
ATTM AM HOLDING ONTO MVFR. BWI/MTN/DCA ALL RECEIVED RAFL. WHETHER
IFR VSBYS REALIZED OR FOG BECOMES MORE WIDESPREAD ARE ISSUES THAT
CAN BE ADDRESSED.
RESTRICTIONS SHUD LIFT AOB MID MRNG. ANOTHER PD OF SCTD
CONVECTION EXPECTED TUESDAY AFTERNOON. TIMING/LOCATION
UNCERTAINTIES PRECLUDE TAF MENTION AT THIS TIME FRAME.
BACKDOOR COLD FRONT EXPECTED TO MOVE THRU THE ERN TERMINALS TUE NGT.
ONSHORE FLOW ON THE COOL SIDE OF THE BOUNDARY WILL FAVOR DEVELOPMENT
OF STRATUS AND FOG. FLIGHT RESTRICTIONS MAY LOWER TO IFR ESPECIALLY
FROM LOW CIGS. LOW CLOUDS MIX OUT WED MRNG...ALTHOUGH MVFR/IFR MAY
LINGER INTO THE MIDDAY HRS TOWARD BWI/MTN WHERE COLD WEDGE WILL
LIKELY BE MOST STUBBORN TO ERODE. SHOWERS AND STORMS POSSIBLE
MAINLY DURING THE AFTN/EVE HRS BOTH WED AND THU. THE BEST CHANCE
WILL BE OVER THE MTS...IN VC OF CHO/MRB.
A STRONG COLD FRONT IS EXPECTED TO BRING NUMEROUS SHOWERS/STORMS
WITH POSSIBLE HEAVY RAIN FOR THURSDAY NIGHT INTO FRIDAY. SOUTHERLY
WINDS WILL INCREASE AHEAD OF THE FRONT WITH LLWS POSSIBLE THURSDAY
NIGHT INTO FRIDAY...AND THERE WILL BE A WIND SHIFT THE NORTHWEST
FRIDAY.
&&
.MARINE...
SLY CHANNELING HAS RELAXED AT THIS PT. ANTICIPATE SCA WL EXPIRE ON
TIME AT 10PM.
WIND SHIFT IS EXPECTED ON TUESDAY AS COLD FRONT MOVES SOUTH.
MAINLY DIURNAL THUNDERSTORMS ARE POSSIBLE.
HIPRES CENTERED OVER THE GULF OF MAINE WILL BUILD SWWD TOWARD THE
WATERS TUE NGT AND WED...RESULTING IN WINDS BACKING FROM THE EAST
DURING THIS TIME. WIND SPEEDS SHOULD REMAIN BELOW SCA THRESHOLD
WITHOUT A FAVORABLE DIRECTION FOR CHANNELING.
A COLD FRONT WILL SLOWLY ADVANCE EWD TOWARD THE WRN SIDE OF THE
APPALACHIANS WED NGT AND THU. THE PRESSURE GRADIENT WILL INCREASE AS
HIPRES IS ANCHORED OFFSHORE AND MULTIPLE WAVES OF LOPRES TRACK ALONG
THE FRONTAL BOUNDARY TO OUR WEST. SCA MAY BE REQUIRED FOR A PORTION
OF THE AREA LATE WED NGT...PARTICULARLY THOSE SUSCEPTIBLE TO SLY
CHANNELING AND POTENTIALLY ALL MARINE ZONES BY THU AFTN.
UNSETTLED WEATHER CONDITIONS WITH NUMEROUS SHOWERS/STORMS AND
POSSIBLE HEAVY RAIN ARE EXPECTED THURSDAY NIGHT INTO FRIDAY DUE TO
A STRONG COLD FRONT. SOUTHERLY WINDS WILL INCREASE AHEAD OF THE
FRONT THURSDAY NIGHT...AND THERE WILL BE A WIND SHIFT TO THE
NORTHWEST FRIDAY. SCA LIKELY THU NGT AND FRI AHEAD OF THE FRONT.
&&
.TIDES/COASTAL FLOODING...
TIDAL SITES CURRENTLY NEAR ASTRONOMICAL TIDE ALONG THE WRN SHORE
OF THE CHSPK BAY AND TIDAL POTOMAC RIVER. POSITIVE TIDAL
ANOMALIES ARE EXPECTED TO DEVELOP TUE NGT AND WED AS THE ARRIVAL
OF A BACKDOOR COLD FRONT MARKS THE ONSET OF ONSHORE FLOW. MINOR
COASTAL FLOODING MAY DEVELOP LATE IN THE WEEK WHEN THESE POSITIVE
ANOMALIES INCREASE UNDER STRENGTHENING SLY FLOW AHEAD OF A SLOW-
MOVING COLD FRONT. ASTRONOMICAL TIDES WILL ALREADY BE HIGH WITH A
FULL MOON THIS WEEK.
