AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OH
306 PM EDT MON MAY 11 2009

.SYNOPSIS...
HIGH PRESSURE WILL SETTLE OVER THE EASTERN GREAT LAKES TONIGHT AND
REMAIN IN PLACE THROUGH WEDNESDAY. A STRONG COLD FRONT WILL SWEEP
THROUGH OHIO AND PENNSYLVANIA THURSDAY BEFORE HIGH PRESSURE RETURNS
ON FRIDAY.

&&

.NEAR TERM /THROUGH TONIGHT/...
QUITE A BIT OF CLOUD COVER ACROSS THE FORECAST AREA AS OF 2PM.
PRECIP ACROSS SOUTH-CENTRAL OHIO AND WESTERN PENNSYLVANIA SHOULD
STAY SOUTH OF THE FORECAST AREA BUT A FEW SHOWERS HAVE DEVELOPED
NEAR YOUNGSTOWN/CANTON/MILLERSBURG. I WILL MENTION SHOWERS AND
THUNDERSTORMS EARLY THIS EVENING...OTHERWISE I WILL GO WITH A DRY
FORECAST TONIGHT. A LOT OF THE CLOUD COVER APPEARS TO BE DIURNAL IN
NATURE AND I SUSPECT SKIES WILL BECOME MOSTLY CLEAR QUICKLY THIS
EVENING. SOME CLOUD COVER OVER LOWER ONTARIO WILL HANG ON A BIT
LONGER HOWEVER I THINK MOST OF THE AREA WILL BE CLEAR WELL BEFORE
MIDNIGHT.

OBVIOUS CONCERNS TONIGHT ARE ON FROST POTENTIAL. THERE IS A STRONG
DEWPOINT GRADIENT ACROSS NW OH AT THE MOMENT...DEWPOINTS AT TOL/TDZ
IN THE LOWER 20S WHILE DEWPOINTS AT FINDLAY...LORAIN...AND POINTS
EAST ARE IN THE LOW 40S. THIS DEWPOINT BOUNDARY WILL SLOWLY DRIFT
THROUGH THE AREA THIS EVENING LEAVING MOST LOCATIONS WITH ABUNDANT
DRY AIR. THAT ALONG WITH CLEAR SKIES AND LIGHT WINDS LEADS ME TO
BELIEVE THAT FROST IS INEVITABLE ACROSS MOST OF THE AREA TONIGHT. I
WILL ISSUE A FROST ADVISORY FOR THE ENTIRE AREA FOR TONIGHT. I THINK
SOME SPOTS WILL BE HIT AND MISS WITH THE FROST...HOWEVER I THINK THE
ADVISORY AND A MENTION OF AREAS OF FROST IN THE FORECAST IS THE WAY
TO GO. I AM CONCERNED ABOUT TEMPS DROPPING BELOW FREEZING ACROSS
EASTERN ERIE/CRAWFORD COUNTIES IN PENNSYLVANIA. THESE AREAS
TYPICALLY GET COLD IN REGIMES LIKE THIS AND I WILL PASS THESE
CONCERNS ALONG TO THE NEXT SHIFT. NOT CONFIDENT ENOUGH TO GO WITH A
FREEZE WARNING FOR ERIE/CRAWFORD BUT IT MAY BE CLOSE.

&&

.SHORT TERM /TUESDAY THROUGH THURSDAY NIGHT/...
FOLLOWING THE MORNING FROST...THE WEATHER SHOULD BE RELATIVELY
UNEVENTFUL THROUGH WEDNESDAY AFTERNOON. HIGH PRESSURE WILL REMAIN
OVERHEAD TUESDAY AND WILL RETREAT OFF THE MID ATLANTIC COAST ON
WEDNESDAY. A STRONG COLD FRONT WILL APPROACH THE REGION WEDNESDAY
AFTERNOON...I BUMPED UP POPS A LITTLE BIT PER THE 12Z NAM SOLUTION.
THE GFS HAD A OBVIOUS CONVECTIVE BULLSEYE ACROSS SOUTHERN
OHIO/KENTUCKY AND ITS SOLUTION WAS TOSSED OUT ACCORDINGLY. I SUSPECT
SOME SHOWERS AND THUNDERSTORMS WILL DEVELOP AHEAD OF THE FRONT AND
MAKE IT INTO AT LEAST THE WESTERN HALF OF THE AREA WEDNESDAY
AFTERNOON. COVERAGE WILL DIMINISH A BIT WEDNESDAY EVENING WITH THE
LOSS OF HEATING BUT PICK UP AFTER MIDNIGHT COINCIDENT WITH THE COLD
FRONTAL PASSAGE. I WAS SOMEWHAT GENERIC WITH THE TIMING AND WORDING
WEDNESDAY NIGHT...THE MODELS ARE HANDLING THE TIMING OF THE FRONTAL
PASSAGE A BIT SLOWER TODAY. I DONT KNOW IF THIS IS BECAUSE OF THE
CONVECTIVE FEEDBACK ISSUE TO OUR SOUTH OR IF THE FRONT WILL REALLY
HOLD OFF MOVING THROUGH THE AREA UNTIL MID MORNING THURSDAY. FOR NOW
I STUCK WITH THE IDEA THAT THE FRONT WILL MOVE THROUGH AROUND 12Z
THURSDAY AND BE THROUGH THE AREA BY 18Z. MOST OF THE FORECAST AREA
SHOULD BE DRY BY NOON THURSDAY ASIDE FROM A LINGERING SHOWER IN THE
EXTREME EASTERN COUNTIES. OTHERWISE DRY WEATHER AND HIGH PRESSURE
RETURNS THURSDAY NIGHT.

&&

.LONG TERM /FRIDAY THROUGH MONDAY/...
SURFACE HIGH PRESSURE WILL SLIDE EAST OF THE REGION ON FRIDAY AS A
STORM SYSTEM TAKES SHAPE ACROSS THE PLAINS. AS THE SURFACE LOW
APPROACHES WE WILL SEE A COLD FRONT APPROACH THE REGION ON
SATURDAY. THIS WILL BRING INCREASED CHANCES FOR THUNDERSTORMS
ALONG AND AHEAD OF THE FRONT. THESE CHANCES WILL DECREASE AS THE
FRONT PASSES ON SUNDAY WITH SURFACE HIGH PRESSURE BUILDS IN BY
LATE MONDAY.

HIGH TEMPERATURES WILL REACH THE LOWER 70S FOR MOST LOCATIONS ON
FRIDAY INTO SATURDAY BUT COOL INTO THE 60S FOR SUNDAY INTO MONDAY
IN THE WAKE OF THE FRONT.

&&

.AVIATION /19Z MONDAY THROUGH SATURDAY/...
WEAK SURFACE TROUGH HAS SHIFTED TO NEAR A MOUNT VERNON TO
YOUNGSTOWN LINE. THIS BOUNDARY LOOKS TO BE THE MAIN FOCUS FOR
SHOWERS/THUNDERSTORMS AS IT CONTINUES A SLOW SOUTHWARD PUSH. WILL
ALSO HAVE TO WATCH ALONG THE LAKE BREEZE THAT IS DEVELOPING TO SEE
IF ANY SHOWERS/THUNDERSTORMS CAN DEVELOP ALONG IT. MAIN AREA OF
CONCERN FOR THIS DEVELOPMENT WILL BE FOR KCAK AND KYNG. FOR NOW
WILL ONLY MENTION A CB IN THE FORECAST FOR THESE TAF SITES
THROUGH 21Z-22Z.

CLOUDS WILL DECREASE SHORTLY AFTER SUNSET WITH SKIES BECOMING
CLEAR AT SOME POINT LATE IN THE EVENING. NORTHERLY WINDS WILL
BECOME LIGHT AND VARIABLE OVERNIGHT AS HIGH PRESSURE BUILDS OVER OHIO.

OUTLOOK...NON VFR LATE WEDNESDAY INTO THURSDAY IN SHOWERS AND
THUNDERSTORMS ASSOCIATED WITH A COLD FRONT.

&&

.MARINE...
MODELS IN GOOD AGREEMENT ON WEATHER PATTERN NEXT FIVE DAYS SO FEEL
FAIRLY CONFIDENT IN GENERAL FORECAST. HIGH PRESSURE MOVING ACROSS
THE LAKE THROUGH TUESDAY WILL MEAN LIGHT AND VARIABLE WINDS THAT
INCREASE OUT OF THE SE THEN S LATE TUE NIGHT THROUGH WED.  WINDS
SPEEDS OF 25 KNOTS ARE POSSIBLE WED NIGHT JUST AHEAD OF A COLD FRONT
THAT WILL CROSS THE LAKE A CREATE A WIND SHIFT TO THE WEST WITH
DIMINISHING FLOW LATER THU AND THU NIGHT.  HIGH PRESSURE CROSSING
THE LAKE LATE THU NIGHT AND EARLY FRI SHOULD MEAN LIGHT AND VARIABLE
FLOW THAT SHOULD BECOME E TO SE FRI NIGHT.

&&
