AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON OH 1040 AM EDT TUE JUN 15 2004 .DISCUSSION... SURFACE ANALYSIS SHOWS A WEAK FRONTAL BOUNDARY EXTENDING FROM LAKE ERIE INTO NORTH CENTRAL INDIANA. A FEW SHOWERS AND THUNDERSTORMS HAVE DEVELOPED ALONG THIS BOUNDARY AND ARE MOVING TOWARDS THE FORECAST AREA. MEANWHILE AREA OF SCATTERED SHOWERS AND THUNDERSTORMS IN KENTUCKY AND TENNESSEE IS MOVING NORTHEAST TOWARDS THE REGION. A GOOD AMOUNT OF HIGH CLOUDS ARE MOVING ACROSS THE AREA BUT BELIEVE THIS SHOULD NOT HAVE TOO MUCH AFFECT ON TEMPERATURES AND SO STILL EXPECT READINGS IN THE MID TO UPPER 80S THIS AFTERNOON. THIS HEATING SHOULD HELP FILL IN CONVECTION MOVING UP FROM THE SOUTH. SOLID CHANCE PROBABILITIES SEEM REASONABLE. MODELS SHOW RATHER WEAK CONVERGENCE THIS AFTERNOON ALONG THE BOUNDARY WHICH WOULD SUGGEST THAT THIS ACTIVITY WILL WEAKEN. BUT STILL NEED TO KEEP LOW CHANCE POPS GOING THERE. && .ILN WATCHES/WARNINGS/ADVISORIES... IN...NONE. KY...NONE. OH...NONE. &&
