Area forecast discussion, Jul 17, 2:15 PM EST, 5 hours 10 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON OH 315 PM EDT TUE JUL 17 2001 19Z SFC ANALYSIS INDICATED A WEAK FRONTAL BOUNDARY ACROSS THE GREAT LAKES STATES. AN OUTFLOW BOUNDARY WAS APPARENT ON THE KILN 88D BTWN ILN AND CMH. SCT SHRA/TSRA WERE OCCURING ACROSS FA. A MORE ORGANIZED AREA OF SHRA/TSRA WERE DROPPING SEWD ACROSS NRN IN. XPCT MCS OVER NRN IN TO MOVE SEWD INTO FA DURING THE LATE PM AND EVENING HOURS. THIS SHOULD BRING MORE WIDESPREAD COVERAGE OF SHRA/TSRA THAN TODAY. WL CARRY LIKELY POPS ALL AREAS TONIGHT. PROGRESSIVE NATURE OF SHRA/TSRA SHOULD PREVENT EXCESSIVE AMOUNTS SO WL NOT MENTION HEAVY RAIN IN FCST. DO NOT TRUST MODEL TIMING FOR THE WED-THU TIME FRAME. SYNOPTIC ENVIRONMENT SUGGESTS THAN ATMOSPHERE WL BE UNSTABLE WITH A BOUNDARY NEARBY THROUGH THOSE PERIODS. XPCT SHRA/TSRA TO PERIODICALLY MOVE FROM NW TO SE ACROSS FA SO WL CARRY CHC POPS. BEST CHANCE OF SVR WL BEE WED PM OR EVENING IF WE GET MORE SS THAN TODAY. TEMPS ARE TOUGH DUE TO UNCERTAINTY OF SHRA/TSRA PLACMENT. WL STICK CLOSE TO GUIDANCE. .ILN...NONE. WILKINSON
