AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OH
307 PM EDT MON AUG 10 2009

.SYNOPSIS...
A SLOW MOVING COLD FRONT WILL DRIFT THROUGH THE LOWER GREAT LAKES
REGION TONIGHT. HIGH PRESSURE WILL RETURN TO THE REGION TUESDAY
AFTERNOON AND WILL REMAIN IN PLACE THROUGH THE END OF THE WEEK.

&&

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
CONVECTION BEGINNING TO DEVELOP ACROSS THE LOWER GREAT LAKES
REGION...MICHIGAN INDIANA AND OHIO ALL SEEING STORMS DEVELOPING. I
SUSPECT THAT STORMS WILL CONTINUE INTO THE EVENING HOURS AS A
PRE-FRONTAL TROUGH SWINGS THROUGH THE AREA...THEN CONTINUE OVERNIGHT
AS THE ACTUAL COLD FRONT MOVES INTO OHIO. I DREW IN SOME FAIRLY HIGH
POPS THIS EVENING AND TAPERED THEM BACK FROM WEST TO EAST AFTER
MIDNIGHT. THE FRONT ITSELF IS STILL BACK OVER CENTRAL WISCONSIN AND
SOUTHERN MINNESOTA SO IT WILL BE A WHILE BEFORE IT MAKES IT TO THE
FORECAST AREA. IT WILL MOVE THROUGH THE AREA LATE TONIGHT WITHOUT
ANY DAYTIME HEATING TO AID THE CONVECTION SO I AM A LITTLE UNSURE OF
WHAT SHAPE THE STORMS WILL BE IN BY THE TIME THEY GET HERE. BEST
THREAT FOR ANY SEVERE WEATHER APPEARS TO BE THIS AFTERNOON AND
EVENING.

&&

.SHORT TERM /6 AM TUESDAY MORNING THROUGH THURSDAY NIGHT/...
THE FRONT WILL STILL BE CLOSE TO THE FORECAST AREA TUESDAY MORNING
SO I CANNOT RULE OUT THE CHANCE OF A MORNING SHOWER OR THUNDERSTORM.
A FEW SHOWERS COULD LINGER INTO THE AFTERNOON HOURS BUT THIS WOULD
LIKELY BE CONFINED TO THE SOUTHERN TIER COUNTIES AND I TRENDED THE
FORECAST IN THAT DIRECTION. FROM TUESDAY NIGHT ONWARD SURFACE HIGH
PRESSURE SHOULD BE IN CONTROL OF THE WEATHER WITH DRY CONDITIONS AND
NEAR NORMAL TEMPERATURES BOTH WEDNESDAY AND THURSDAY.

&&

.LONG TERM /FRIDAY THROUGH MONDAY/...
SURFACE HIGH PRESSURE WILL SHIFT TOT HE EAST COAST OF THE US ON
FRIDAY ALLOWING WARM MOIST AIR TO FLOW BACK INTO NORTHERN OHIO AND
NW PA. MODELS CONTINUE TO STRUGGLE WITH THE MOVEMENT OF A WEAK AREA
OF LOW PRESSURE ROTATING AROUND UPPER LEVEL HIGH PRESSURE THAT IS
CENTERED OFF THE SOUTH CAROLINA COAST. FOR NOW WILL HOLD OFF ON A
MENTION OF SHOWERS AND THUNDERSTORMS WITH MUCH OF THE FORCING
REMAINING NEAR THE OHIO RIVER VALLEY.

OTHERWISE IT LOOKS LIKE ABOVE AVERAGE TEMPERATURES THROUGH THE
WEEKEND.

&&

.AVIATION /19Z MONDAY THROUGH SATURDAY/...
THUNDERSTORMS ALREADY DEVELOPING NEAR AND AHEAD OF A TROUGH AXIS
THAT IS LOCATED FROM SOUTHERN ONTARIO INTO NORTHWESTERN OHIO.
APPEARS THAT KTOL IS IN THE CLEAR AND KFDY HAS ONLY A SMALL WINDOW
OF OPPORTUNITY THROUGH 19Z-20Z. ADDITIONAL CONVECTION IS
DEVELOPING ALONG THE HIGHER TERRAIN OF NW PA INTO ASHTABULA
COUNTIES. THIS CONVECTION MAY MOVE VERY LITTLE SO THIS COULD BE A
PROLONGED PERIOD OF RAINFALL. ERIE WILL GET ANOTHER ROUND OF
THUNDERSTORMS OFF OF LAKE ERIE AFTER 20Z.

ELSEWHERE STRONG TO SEVERE CONVECTION WILL CONTINUE TO DEVELOP WITH
STRONG GUSTY WINDS POSSIBLE. AS TROUGH AXIS PASSES THE MVFR/IFR
CONDITIONS SHOULD IMPROVE THROUGH THE EVENING. WILL THEN HAVE TO
WATCH FOR A RETURN OF SOME LOWER CEILINGS AND FOG AHEAD OF A COLD
FRONT THAT WILL ARRIVE TUESDAY MORNING.

.OUTLOOK...SOME MVFR CEILINGS POSSIBLE INTO TUESDAY MORNING. OTHER
MAINLY VFR.

&&

.MARINE...
STORMY WEATHER FOR THE REMAINDER OF THE AFTERNOON WITH FRONT STILL
WAY BACK TO THE WEST. BE ALERT FOR ANY WARNINGS.  COLD FRONT TO MAKE
ITS WAY ACROSS THE LAKE TOWARD MORNING AND IT MAY DO SO RELATIVELY
QUIETLY. LIGHT WEST-NORTHWEST FLOW TONIGHT INTO TUESDAY. WEDNESDAY
EXPECT VARIABLE/ONSHORE FLOW TO DEVELOP WITH HIGH PRESSURE BUILDING
IN. THE HIGH WILL SLOWLY MOVE EASTWARD OVER THE COURSE OF THE
WEEK...MOVING EAST OF THE LAKE AND DEVELOPING SOUTHEAST FLOW TOWARD
THE WEEKEND. AFTER TODAY/TONIGHT/S WEATHER...WEATHER ON THE LAKE
WILL BE MUCH QUIETER.

&&

.CLE WATCHES/WARNINGS/ADVISORIES...
OH...NONE.
PA...NONE.
MARINE...NONE.
