AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PITTSBURGH PA
147 AM EDT SUN MAY 11 2008

.SYNOPSIS...

A LARGE AND DEEP STORM SYSTEM WILL MOVE ACROSS THE AREA TONIGHT.
THIS WILL BRING A GOOD DOSE OF RAIN TO THE AREA THROUGH MONDAY.
DRY WEATHER WILL RETURN ON TUESDAY.

&&

.NEAR TERM /THROUGH TODAY/...

A LARGE AND DYNAMICAL SYSTEM WILL MOVE TOWARD THE AREA TODAY. THIS
WILL PUSH PLENTY OF RAIN INTO THE AREA INTO THE AFTERNOON HOURS.
AGAIN THIS MORNING...SOME TIMING DIFFERENCES WITH MODEL
SOLUTIONS. NAM REMAINS THE SLOWEST...WITH GFS AND 21Z SREF SHOWING
FASTER EASTWARD MOVEMENT. HAVE GONE WITH THE QUICKER BEGINNING TO
RAIN BUT NOT AS FAST AS SREF. ONE CONCERN I HAVE FOR TIMING IS THE
CONVECTION OVER THE GULF COAST STATES...WHICH SHOULD HELP TO
STRENGTHEN CURRENT EASTERN RIDGE AND SLOW THE PROGRESSION OF RAIN.
EXPECT MOST IF NOT ALL OF THE AREA TO BE UNDER THE RAIN SHIELD BY
THIS AFTERNOON. LITTLE TO NO INSTABILITY AND WITH UL SYSTEM
BEGINNING TO OPEN UP AND MOVE SE WILL LEAVE OUT MENTION OF
THUNDER. ALTHOUGH A LINE OF TRW IS POSSIBLE THIS AFTERNOON...RIGHT
NEAR THE FRONTAL BOUNDARY...ACROSS THE SOUTH.

&&

.SHORT TERM /TONIGHT THROUGH TUESDAY/...

ENTIRE SYSTEM SHOWING WINTER STORM CHARACTERISTICS TONIGHT AS
ENERGY RAPIDLY TRANSFERS TO THE CHESAPEAKE BAY. SYSTEM OCCLUDES
LATE TONIGHT AND EASTWARD MOVEMENT IS SLOWED AS UL PATTERN IS
SHOWING BRIEF OMEGA BLOCK. THIS SLOW EXIT WILL KEEP RAIN IN
THROUGH MOST OF MONDAY. WITH PLENTY OF CLOUDS...RAIN AND COLD AIR
ALOFT...TEMPS WILL BE WELL BELOW NORMAL MONDAY.

STRONG RIDGING WILL ENSUE TUESDAY IN RESPONSE TO DEEP SYSTEM OFF
THE NE COAST. THIS WILL ALLOW FOR VERY DRY AIR TO MOVE IN TUESDAY.
EXPECT PLENTY OF SUNSHINE AND CLOSER TO NORMAL TEMPS TUESDAY.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...

CHANGES AGAIN TO EXTENDED PERIOD AS LATEST GFS IS NOW SHOWING NO
PHASING OF CF AND SFC LOW OVER TX. FRONT PUSHES THROUGH WED NIGHT-
THU...BRINGING CHANCE OF RAIN AND THEN MOVES WELL EAST AS LOW
DEVELOPS OVER TX. LOW MOVES ALONG STALLED FRONT THU AND FRIDAY...
BUT BY THEN...FRONT IS WELL SOUTH OF THE AREA. HAVE NOT MADE
DRASTIC CHANGES TO THE EXT...JUST PULLED BACK A BIT ON POPS THU-
FRI. IF CURRENT SOLUTION IS RIGHT...MOST OF THE EXT WILL BE RAIN
FREE.

THE ECMWF IS ALSO SHOWING LESS RAIN CHANCES FOR THE EXT.

HIGH PRESSURE MOVES IN FOR THE WEEKEND.

&&

.AVIATION /05Z SUNDAY THROUGH THURSDAY/...

PREVAILING VFR CONDITIONS INTO UNTIL MID MORNING WHEN MOISTURE WILL
INCREASE AHEAD OFF DEEPENING SYSTEM MOVING INTO THE WESTERN OHIO
VALLEY BY THIS AFTERNOON. CLOSED LOW ALOFT WILL MOVE ACROSS OHIO
VALLEY TONIGHT WITH RAIN SHIELD AND LOWER CIGS LATER THIS AFTERNOON
AND TONIGHT BRINGING MVFR CONDITIONS BY LATE DAY. IFR EXPECTED TO
DEVELOP OVERNIGHT BUT WILL TRY TO PIN DOWN BETTER TIMING OF THIS FOR
12Z TERMINALS. AS SYSTEM EXITS MONDAY IFR IN THE MORNING SHOULD
GRADUALLY IMPROVE TO MVFR DURING THE DAY. RIDGE SURFACE AND ALOFT
FOR VFR LATER MONDAY NIGHT INTO EARLY WEDNESDAY. COLD FRONT
APPROACHES WEDNESDAY AFTER WITH MVFR POSSIBLE LATE IN SHOWERS. WEAK
SURFACE HIGH FOR GENERAL VFR THURSDAY.
