.SHORT TERM /FRIDAY NIGHT THROUGH SATURDAY/...
THE UPPER TROUGH AXIS WILL PASS THROUGH THE REGION ON FRI...THEN
LINGER NEAR THE COAST IN THE AFTN AND EVENING BEFORE PUSHING OUT
TO SEA AFTER MIDNIGHT. A WEAK IMPULSE WILL DIVE SSE INTO THE BASE
OF THE TROUGH AND HELP TO SET OFF SOME LIGHT RAIN SHOWERS AND
POSSIBLY A FEW THUNDERSTORMS MAINLY EAST OF I-95 IN VA (INCLUDING
THE MD/VA EASTERN SHORE AND PORTIONS OF NE NC). THE BEST CHANCES
FOR MORE SCATTERED CONVECTION IS OVER THE NRN NECK AND MD/VA
EASTERN SHORE. ALL PRECIP ACTIVITY IS EXPECTED TO TAPER OFF BY
SUNSET WITH THE LOSS OF DAYTIME HEATING. OVERALL...THE DAY WILL
START OUT MOSTLY SUNNY AND THEN CUMULUS CLOUDS WILL QUICKLY
DEVELOP IN THE AFTN DUE TO LINGERING LOW LEVEL MOISTURE IN PLACE
AND ALSO BECAUSE OF THE UPPER TROUGH PRODUCING MID AND UPPER LEVEL
INSTABILITY. MEANWHILE...DRIER AND COOLER AIR WILL BE MOVING INTO
THE MID ATLANTIC REGION BEHIND THE UPPER TROUGH. THIS WILL RESULT
IN HIGH TEMPS AROUND 5 DEGREES ABOVE NORMAL...OR IN THE UPPER 70S
TO LOWER 80S (MID-UPPER 70S IMMEDIATE COAST).

TO REITERATE...THE UPPER TROUGH PUSHES OUT TO SEA BY SAT MORNING.
THE DAY WILL START OUT NICE AND COOL WITH LOWS GENERALLY IN THE
UPPER 50S TO LOWER 60S (OR NEAR NORMAL). SFC HIGH PRESSURE THEN
BUILDS IN FROM THE NW AND SLIDES TO THE SE (AND EVENTUALLY OFFSHORE)
SUN INTO SUN NIGHT. AS THE HIGH SLIDES SE OF THE AREA...WINDS WILL
CHANGE FROM N-NW TO S-SW AND RESULT IN A GRADUAL WARMING TREND
THROUGH THE REST OF THE WEEKEND. HIGHS SAT SHOULD BE IN THE
LOW-MID 80S (UPPER 70S-LOWER 80S IMMEDIATE COAST). A ZONAL WEATHER
PATTERN DEVELOPS IN THE MID AND UPPER LEVELS SUN INTO MON AND
OPENS THE DOOR FOR WEAK IMPULSES OF ENERGY/MOISTURE TO CROSS THE
MID ATLANTIC REGION DURING THIS TIME. EXPECT INCREASING HIGH AND
MID LEVEL CLOUDS ON SUN WITH SHOWERS AND THUNDERSTORMS DEVELOPING
FROM NW TO SE THROUGHOUT THE AFTN AND EVENING. FOR SUN...LOWS IN
THE 60S AND HIGHS IN THE MID-UPPER 80S.

&&

.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
LONG TERM PERIOD WILL FEATURE HI PRES OFF THE SE U.S. COAST LEADING
TO WARM TEMPS AND SWLY FLOW ON AVG OVER THE MID ATLANTIC. CHCS FOR
SHOWERS AND TSTMS WILL BE ARND FOR SUN NGT THRU LATE TUE/TUE
NGT...AS A COUPLE OF TROFS AFFECT THE AREA FOLLOWED BY A COLD FRONT
MOVING THRU LATE TUE/TUE NGT. HI PRES WILL THEN BLD INTO THE REGION
DURING WED AND THU. LOW TEMPS THRU THE PERIOD WILL BE IN THE UPR 60S
TO LWR 70S...WITH HIGHS IN THE MID TO UPR 80S.

&&

.AVIATION /01Z FRIDAY THROUGH TUESDAY/...
A STRONG COLD FRONT IS CONTINUING TO PUSH THROUGH WEST VIRGINIA WITH A
LINE OF STRONG THUNDERSTORMS PUSHING OUT AHEAD OF THE FRONT.
EXPECT THE LINE OF STORMS TO PUSH NW TO SE ACROSS THE AREA THURS
AFTN/EVENING. TEMPO GROUPS HAVE BEEN ADDED TO ACCOUNT FOR THE PERIOD OF
STRONG THUNDERSTORMS WITH WINDS GUSTING TO 30KT...WITH ISOLATED
WIND GUSTS OF 50KT...AND VISIBILITIES REDUCED TO LESS THAN 1 MILE
IN THE HEAVY RAIN. EXPECT THE LINE TO MOVE THROUGH RIC AROUND 19Z
AND PUSH THROUGH PHF/ORF AROUND 22Z AND THROUGH ECG BY 23Z.

WINDS WILL VEER TO THE NNW/N OVERNIGHT AFTER FRONTAL PASSAGE AND
REMAIN FAIRLY STRONG THROUGH FRI AFTN...GUSTING TO ~20KT. AN

HI PRES RETURNS.

.MARINE...
SCA`S REMAIN IN EFFECT FOR ALL WATERS THRU FRIDAY AFTN...MAINLY FOR
WINDS OVER THE BAY/RIVERS/SOUND AND SEAS OVER CSTL WTRS. A STRONG
LOW PRESSURE SYSTEM AND ASSOCIATED COLD FRONT WILL TRACK ACROSS THE
MID-ATLANTIC REGION LATE THIS AFTN INTO TONIGHT. SW WINDS 15 TO 20
KT WITH GUSTS TO 25 KT WILL OCCUR IN ADVANCE OF THE FRONT...THEN
WINDS SHIFT TO THE NW THEN N TONIGHT INTO FRI MORNING BEHIND THE
FRONT. MODELS STILL HINT AT THE POSSIBILITY OF SOME GALE FORCE WIND
GUSTS TONIGHT/EARLY FRI BEHIND THE FRONT BUT CONFIDENCE IS STILL NOT
HIGH ENOUGH FOR A GALE WARNING. IN ADDITION...SOME WIND GUSTS IN
EXCESS OF 50 KT ARE POSSIBLE WITH A LINE OF STRONG TO SEVERE TSTMS
EXPECTED TO MOVE ACROSS THE WATERS LATER TODAY.

CONDITIONS START TO IMPROVE BY LATE FRIDAY INTO SAT...AS HIGH PRES
