AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OH
1038 PM EDT WED AUG 24 2011

.SYNOPSIS...
A SHARP COLD FRONT WILL CROSS THE REGION TONIGHT AND BE PRECEDED
AND ACCOMPANIED BY SOME GUSTY THUNDERSTORMS. COOLER AND DRIER AIR
WILL FOLLOW ON THURSDAY AS HIGH PRESSURE BUILDS SOUTH AND EAST
ACROSS THE LAKES. FINE LATE SUMMER WEATHER WILL THEN PREVAIL
FRIDAY AND ON THROUGH THE WEEKEND AS THE HIGH DRIFTS SLOWLY TO THE
EAST.

&&

.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
LOOKING TOWARD SEVERE WEATHER ROLLING ACROSS THE AREA TONIGHT.
WIND AND HAIL BIGGEST RISK...BUT STILL CAN NOT RULE OUT A TORNADO.
PARAMETERS STRONG ENOUGH TO WARRANT AN UPGRADE TO A TORNADO WATCH
BOX. LINE OF CONVECTION EXTENDS FROM ONTARIO INTO NORTHWEST OHIO
AND CENTRAL INDIANA.

FOLLOWING THIS ROUND OF STORMS...ACTUAL COLD FRONT WORKS ACROSS THE
AREA 09-13Z THURSDAY...AS THERE SHOULD BE A LULL AFTER THE STORMS
AND PRIOR TO THE FRONT. MILD NIGHT AS MUCH OF THE NIGHT REMAINS IN
THE WARM SECTOR.

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH SATURDAY NIGHT/...
CLOUDS SHOULD GRADUALLY MIX OUT THURSDAY MORNING BUT IT MIGHT TAKE
A WHILE...ESPECIALLY IN UPSLOPE AREAS SOUTH AND EAST OF CLEVELAND
AND OVER NW PA. MAY ALSO SEE ANOTHER SURGE OF WRAPAROUND
CLOUDINESS DURING MIDDAY/EARLY AFTERNOON BUT MOST OF THAT SHOULD
SLIDE TO OUR NORTH AND EAST...PERHAPS CLIPPING NW PA...BUT ONLY
INCLUDED SLIGHT CHANCE POPS THERE. H8 TEMPS FALL TO 12C OR SO
THURSDAY AFTERNOON SO TEMPS SHOULD HOLD IN MID/UPPER 70S...BUT ALL
IN ALL A VERY COMFORTABLE DAY WITH AMPLE SUNSHINE...EVENTUALLY.

OVERALL WEATHER PATTERN WILL BE DICTATED TO A MAJOR DEGREE BY
IRENE. WE WILL NOT BE IMPACTED DIRECTLY BY THE TROPICAL SYSTEM...WE
ARE WELL WEST OF IT. HOWEVER...IT WILL ACT TO SLOW DOWN THE
EASTWARD PROGRESSION OS SYSTEMS UPSTREAM OF OUR CWA. WEAK RIDGING
ALOFT WILL BUILD IN ACROSS OHIO THURSDAY NIGHT THROUGH FRIDAY THEN
THE RIDGE SHARPENS AS A RESULT OF IRENE/S NORTHWARD MOVEMENT.

AS WE GET INTO SATURDAY...THE WEAK SURFACE FRONTAL SYSTEM THAT IS
EXPECTED TO WORK ITS WAY SOUTH FROM THE UPPER GREAT LAKES WILL ALL
BUT DISSIPATE SINCE OHIO WILL BE IN THE LARGE SCALE SUBSIDENCE TO
THE NORTHWEST OF IRENE...THEREBY EXTENDING DRY WEATHER ACROSS THE
AREA THROUGH SATURDAY.

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
FOR THE REST OF THE WEEKEND...OHIO WILL REMAIN JUST TO THE WEST OF
THE CIRCULATION ASSOCIATED WITH IRENE AND THEREFORE WILL STAY UNDER
A SURFACE HIGH PRESSURE SYSTEM AND DRY CONDITIONS THROUGH THE
PERIOD. AS FAR AS TEMPERATURES...LACK OF CLOUD COVER SHOULD DROP
TEMPERATURES AT NIGHT JUST A BIT BELOW NORMALS FOR THIS TIME OF
THE YEAR WITHIN A FEW DEGREES OF 60. DAYTIME HIGHS SHOULD RANGE IN
THE MID TO UPPER 70S.

IN THE MONDAY TO TUESDAY TIME FRAME...I AM A BIT LESS CONFIDENT
IN THE TIMING OF THE NEXT WEATHER SYSTEM AND ACCOMPANYING
POTENTIAL FOR RAINFALL. MANUAL GRAPHICS SEEM TO FOLLOW MORE OF AN
ECMWF SOLUTION WHICH BRINGS THE NEXT BATCH OF RAINFALL TO THE
REGION TUESDAY. AT THIS POINT...I PLAN TO FOLLOW THAT LINE OF
THOUGHT AND BRING CHANCE POPS TO THE REGION MONDAY NIGHT INTO
TUESDAY.

&&

.AVIATION /03Z THURSDAY THROUGH MONDAY/...
ALL SITES VFR AT 00Z WITH MAIN THREAT THE TIMING OF A LINE OF
SHOWERS/THUNDERSTORMS ASSOCIATED WITH A COLD FRONT WHICH SHOULD
EVENTUALLY DEVELOP AND CROSS OUR REGION FROM NORTHWEST TO
SOUTHEAST LATER THIS EVENING AND OVERNIGHT. ACTIVITY HAS BEEN
DELAYED BUT STILL EXPECT SOME DEVELOPMENT SO USED A TEMPO GROUP
FOR TS FOR A 2-3 HOUR PERIOD BEGINNING AT 02Z TOL AND 03-04Z AT
CLE/ERI. MVFR CEILINGS WILL FOLLOW AFTER FROPA...GRADUALLY
THINNING LATER THURSDAY MORNING. THE POTENTIAL FOR STRONG WINDS
WILL EXIST WITH THE LINE OF STORMS.

OUTLOOK...THURSDAY...VFR/MVFR CIGS. FRIDAY THROUGH MONDAY...MAINLY
VFR.

&&

.MARINE...
WILL EXTEND THE SMALL CRAFT ADVISORIES THROUGH 4 AM THURSDAY TO
ACCOUNT FOR THE STRONG SOUTHERLIES AHEAD OF THE COLD FRONT THIS
EVENING...AND THE ASSOCIATED CONVECTION WITH THE FRONT. WAVE
ACTION MOSTLY OFFSHORE WITH THE SOUTHERLIES...BUT WINDS STRONG
ENOUGH FOR ADVISORIES. WINDS WILL SHIFT TO THE NORTHWEST PRIOR TO
DAYBREAK THURSDAY BUT SPEEDS WILL BE IN THE 10-20 KNOT
RANGE...ALLOWING WAVES TO SUBSIDE BELOW SMALL CRAFT ADVISORY
CRITERIA. LOOK FOR MODERATE NORTHERLIES THROUGH THE
WEEKEND...TENDING NORTHEAST AS TIME WEARS ON.

&&

.CLE WATCHES/WARNINGS/ADVISORIES...
OH...NONE.
PA...NONE.
MARINE...SMALL CRAFT ADVISORY UNTIL 4 AM EDT THURSDAY FOR LEZ142>149.
