NWS Wilmington, OH wrote its last area forecast discussion before the first event at Aug 9, 1:02 PM EST, 2 hours 58 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON OH 202 PM EDT THU AUG 9 2001 SCATTERED AIRMASS CONVECTION AHEAD OF S/W EXPECTED TO CONTINUE INTO THE EVENING. A RELATIVE LULL EXPECTED DURING A PERIOD OVERNIGHT AS THERMAL RIDGE AND MIN IN LLVL RH PROVIDES A BREAK IN MOISTURE AVAILABILITY AND THERMODYNAMIC SUPPORT. HOWEVER...SECOND S/W ASSOCIATED WITH THE FRONT SHOULD PROVIDE STRONG LIFT AND A GOOD CHANCE OF RAIN LATER OVERNIGHT...ESPECIALLY TO THE NORTHWEST. POPS TONIGHT WILL MENTION EVENING WORDING OR THROUGH MIDNIGHT IN EAST/SOUTHEAST AND TRY TO MENTION A BREAK IN THE NORTHWEST BUT WILL GO WITH LIKELY WORDING HERE. WOULD LIKE TO GO WITH THE MENTION OF HEAVY RAIN POSSIBILITY TONIGHT...BUT THINK THAT CONVECTION MAY BE SCATTERED ENOUGH AND MOVE JUST QUICK ENOUGH THAT THIS WOULDNT BE ENTIRELY REASONABLE. WILL TRY AND GET A LITTLE FANCY WITH GFE AND TIMING OF FRONTAL PASSAGE TOMORROW. THIS WILL LIKELY CREATE A GOOFY ZONE BREAKDOWN FROM NW-SE AND AM CONCERNED ABOUT TEMPERATURE SCHEME FOR HIGHS DURING THE DAY. STRONG CAA BEHIND FRONT TODAY WILL LIKELY KEEP READINGS STEADY TO THE NORTHWEST IN THE UPPER 70S BEHIND FRONT. HOWEVER...BEST CAA IS NOTED TODAY AND NOT TOMORROW. COLD POOL STAYS NORTH OF FCST AREA AND SUSPECT THAT SOUTHEAST COULD BE SNEAKY WARM AROUND 90...BUT WOULD NEED A GOOD 2-3 HOURS OF SUNSHINE THAT DOES NOT SEEM TO BE REALIZED BY MODELS HERE. WILL MOS OUT IN SOUTHEAST AND TRY TO UNDERCUT IT FROM THE NORTHWEST AS TEMPS STAY NEARLY STEADY BEHIND FRONT. ON SATURDAY...EXPECT MORE OF THE SAME WITH TEMPERATURES RANGING FROM THE LOW 80S TO THE NORTH WITH SCATTERED PM CU...MIDDLE 80S IN THE SOUTH...DEPENDING STRONGLY ON CLOUD COVER. WILL PROBABLY GO THE MIDDLE GROUND IN ALL AREAS AND JUST OPEN UP AN 80-85 RANGE AS MORE CLOUD COVER EXPECTED IN THE SOUTH. .ILN...NONE. FRANKS
