AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC
303 PM EDT TUE SEP 30 2008

.SYNOPSIS...
A COLD FRONT WILL BRING SOME SHOWERS AND THUNDERSTORMS TO THE MID
ATLANTIC THIS EVENING. UPPER LEVEL LOW PRESSURE PROVIDES A RISK
OF SHOWERS WEDNESDAY. COOL HIGH PRESSURE BUILDS IN FOR THURSDAY
AND FRIDAY.

&&

.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
HEIGHT FALLS WERE BEGINNING TO SPREAD EAST TOWARD THE MID ATLANTIC
THIS AFTERNOON AS A POTENT UPPER LOW WAS DIGGING SOUTH INTO THE
GREAT LAKES. AT THE SURFACE...A LEE TROUGH HAD DEVELOPED JUST EAST
OF THE BLUE RIDGE...AND A COLD FRONT WILL CATCH UP TO THE TROUGH
LATER THIS EVENING AND MOVE EAST THROUGH THE CWA.

OUTSIDE OF AREAS OF MID LEVEL CLOUDS...THERE HAS BEEN SOME
INSOLATION THIS AFTERNOON. DEWPOINTS HAVE BEEN ABLE TO RISE INTO THE
UPPER 50S...EVEN A BIT ABOVE 60 IN A FEW SPOTS. THESE WILL
CONTRIBUTE TO 500 TO POSSIBLY 1000 J/KG CAPE OVER THE NEXT FEW
HOURS. THEREFORE...WE SHOULD BEGIN TO SEE MORE CONVECTIVELY DRIVEN
SHOWERS AND THUNDERSTORMS DEVELOP THROUGH 5 PM. IN
ADDITION...DYNAMICS WILL BECOME BETTER ESTABLISHED ACROSS THE MID
ATLANTIC TOWARD SUNSET. THIS MAY ALLOW FOR SOME ORGANIZATION OF THE
CONVECTION THIS EVENING. FOLLOWED SREFS FOR POP DISTRIBUTION THIS
EVENING...WHICH WAS HIGHER THAN MOS GUIDANCE. HIGHEST POPS /LIKELY/
WILL BE THE BALTIMORE/WASHINGTON CORRIDOR. THIS IS ALSO THE AREA
WHICH MAY BE ABLE TO HAVE LOCALLY STRONG THUNDERSTORMS.

ANY STRONG THUNDERSTORMS SHOULD BE EAST OF THE BAY BY 03Z. THIS IS
SIMULATED WELL BY THE 15Z LWX WRF-ARW. HOWEVER...WITH HEIGHTS
CONTINUING TO FALL TONIGHT AND SOME JET INFLUENCE REMAINING...WILL
KEEP CHANCES OF SHOWERS OVERNIGHT WHICH AGAIN IN NEAR SREF PROBS FOR
MEASURABLE RAINFALL.

&&

.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH 6 PM WEDNESDAY/...
CWA WILL BE UNDER THE INFLUENCE OF AN UPPER TROUGH ON WEDNESDAY.
MODELS FORECAST A STRONG AREA OF POSITIVE VORTICITY ADVECTION IN THE
AFTERNOON...THEREFORE WILL HAVE CONVECTIVE SHOWERS IN THE
FORECAST...HIGHEST POPS NORTH AND LOWEST POPS SOUTH.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH TUESDAY/...
A WESTERN CANADIAN TROUGH/EASTERN CANADIAN RIDGE PATTERN HAS
PROGRESSED TO A WESTERN CANADIAN RIDGE AND DEVELOPING TROUGH OVER
THE GREAT LAKES REGION DURING THE PAST 5 DAYS. WATER VAPOR LOOP
SHOWS THE TROUGH PROGRESSING INTO THE EASTERN GREAT LAKES AND OHIO
VALLEY...WITH ACARS 250-400MB WIND OBSERVATIONS REVEALING A
SOUTHWESTERLY UPPER LEVEL JET OF 100-125KT OVER THE MID ATLANTIC
REGION. 12Z SURFACE MAP PLACED A WARM FRONT FROM LAKE ERIE DOWN INTO
THE CAROLINAS...WITH THE COLD FRONT STRETCHING SOUTHWEST FROM LAKE
ERIE INTO THE PLAINS.

PASSAGE OF MIDLEVEL TROUGH SHOULD SUPPORT UPSLOPE RAIN SHOWERS
ACROSS FAR WESTERN ZONES INTO WEDNESDAY NIGHT...AS PRE-FRONTAL
ACTIVITY CROSSES THE BAY. GIVEN ANTICIPATED MOMENTUM
TRANSFER...WENT ABOVE MOS GUIDANCE FOR LOW TEMPERATURES THURSDAY
MORNING.

BREEZY AND COOL CONDITIONS CONTINUE THURSDAY AS HIGH PRESSURE BEGINS
TO BUILD IN FROM THE WEST. LOWEST TEMPERATURES ANTICIPATED FRIDAY
MORNING AS WINDS DECOUPLE. COULD SEE SOME FROST ACROSS WESTERN
VALLEYS.

ALTHOUGH LONG RANGE SOLUTIONS SIMILAR IN PATTERN PROGRESSION...DID
LEAN TOWARD 00Z EUROPEAN FOR DETAILS. MID CLOUDS INCREASE LATE WEEK
AS A JET ROUNDS THE UPPER LOW TO THE NORTH. HIGH PRESSURE BUILDS
ACROSS NEW ENGLAND THIS WEEKEND...THEN DOWN THE APPALACHIANS EARLY
NEXT WEEK. DECREASED DIURNAL TEMPERATURE RANGE AND INCREASED SKY
COVERAGE AS LOW LEVEL ATLANTIC FLOW MAY OCCUR MONDAY AND TUESDAY.
WILL ALLOW MODELS TO CONVERGE TOWARD A SOLUTION BEFORE ADDING IN
MORE EXTENSIVE CLOUD COVER AND POPS/DRIZZLE IF IT REMAINS WARRANTED.

&&

.AVIATION /19Z TUESDAY THROUGH SUNDAY/...
A COLD FRONT WILL MOVE THROUGH THE TERMINALS THIS
EVENING...PROMOTING A WIND SHIFT TO THE WEST. COULD BE A COUPLE
SHOWERS AND A THUNDERSTORM AHEAD OF THE FRONT...GENERALLY FROM 21Z
TO 02Z. TEMPO GROUP WAS INCLUDED IN 18Z TAF...EXCEPT FOR KCHO. LATER
AT NIGHT...AM CONCERNED THAT IFR FOG MAY DEVELOP AT KCHO/KMRB...WITH
MVFR FOG AT KIAD. INCLUDED IN THE 18Z TAFS AS WELL.

HIGH PRESSURE SLOWLY BUILDS INTO THE REGION FROM THE WEST WEDNESDAY
NIGHT AND THURSDAY BEHIND THE COLD FRONTAL PASSAGE. 10 TO 20 MPH
WINDS CAN BE EXPECTED DURING THIS TIME PERIOD. FLOW WEAKENS AND
BACKS FRIDAY AHEAD OF A COLD FRONT DROPPING SOUTH FROM NEW ENGLAND.
DO NOT ANTICIPATE CEILING/VISIBILITY RESTRICTIONS BEHIND THE COLD
FRONT MID TO LATE WEEK.

&&

.MARINE...
SOUTHEAST FLOW THIS AFTERNOON...THEN SOUTH FLOW THIS EVENING WILL BE
ABLE TO REACH 15 TO 20 KT ESPECIALLY WITH THE AID OF A 25 KT MAX OF
WINDS AT 1-2K FT. WILL BE ISSUING A SMALL CRAFT ADVISORY THROUGH
03Z.

A FRONT WILL MOVE THROUGH THE WATERS OVERNIGHT...PROMOTING A SHIFT
TO THE WEST NORTHWEST LATE AT NIGHT INTO WEDNESDAY.

COLD FRONT WILL BE CLEARING THE WATERS WEDNESDAY NIGHT. INCREASING
PRESSURE GRADIENT AS HIGH PRESSURE BEGINS TO BUILD IN FROM THE WEST
WILL PROVIDE AN OPPORTUNITY FOR SMALL CRAFT ADVISORY WINDS WEDNESDAY
NIGHT AND THURSDAY. FLOW WEAKENS AND BACKS LATE FRIDAY AHEAD OF A
COLD FRONT DROPPING SOUTH FROM NEW ENGLAND.
