FORECAST COORDINATION MESSAGE
NATIONAL WEATHER SERVICE WILMINGTON OH
245 AM EDT TUE JUL 21 1998

FORECAST CHALLENGE...CONVECTION POTENTIAL THROUGH PERIOD.

AT THE MOMENT...IR AND RADAR IMAGERY SHOWING BOW ECHO IN SOUTHERN
ONTARIO AND NORTHERN OH.  SYSTEM WILL STAY WELL NORTH OF CWA.  KILN
AND KIWX SHOWING SOME A SMALL CLUSTER OF TSRA BETWEEN FWA AND LIMA WHICH
ACCORDING TO LAPS DATA IS IN AN AREA OF MOISTURE CONVERGENCE.

MODELS ARE PRETTY SIMILAR WITH THE OVERALL PATTERN.  BERMUDA HIGH
BUILDS IN OVER MUCH OF SOUTHERN OHIO WITH A 700 MB CAP OF 9 TO 10
DEGREES THROUGH MUCH OF THE FORECAST PERIOD.  THIS WILL SUPPRESS
CONVECTION OVER MUCH OF FORECAST AREA...ESPECIALLY SOUTHERN 2/3.
THE MAIN ACTIVITY WILL REMAIN ALONG A NEARLY STATIONARY BOUNDARY IN
SOUTHERN WI/MI AND NORTHERN IL/IN/OH.  THE NORTHERN JET STREAM WILL
PROVIDE THE UPPER LEVEL SUPPORT.  IN FACT ALL THREE MODELS SHOW THE
WHOLE BOUNDARY LIGHTING UP OVERNIGHT TONIGHT.  THE BERMUDA HIGH
BEGINS TO SLIDE SOUTHWARD ON WEDNESDAY AS STATIONARY BOUNDARY DRIFTS
SOUTH INTO NORTHERN AND CENTRAL IL/IN/OH ALONG WITH ASSOCIATED UPPER
LEVEL SUPPORT.

FWC GUIDANCE HAS PRETTY GOOD HANDLE ON POPS AND TEMPS THROUGH PERIOD.
THINK SUMMER TIME POP (30%) NORTH OF DAY AND CMH WOULD BE REASONABLE
FOR TODAY AND ISOLATED OR NO MENTION REST OF CWA.
