AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON OH 300 PM EDT THU AUG 18 2005 .SHORT TERM (TODAY THROUGH FRIDAY NIGHT)... SHOWERS AND THUNDERSTORMS HAVE FILLED IN ACROSS SOUTHERN PORTIONS OF FA OVER THE PAST COUPLE OF HOURS. THESE APPEAR TO BE PRIMARILY DIURNALLY DRIVEN. HOWEVER...MORE ORGANIZED AREAS OF PCPN ACROSS NORTHWEST INDIANA AND WESTERN KENTUCKY WILL LIKELY HOLD TOGETHER PAST SUNSET. IT LOOKS LIKE THE NORTHERN AREA MAY BRUSH ACROSS NORTHERN PORTIONS OF FA THIS EVENING BUT THINK SOUTHERN AREA WILL REMAIN SOUTH OF OUR FA. WILL THEREFORE...DECREASE POPS ACROSS THE SOUTH THIS EVENING BUT KEEP THINGS GOING A LITTLE LONGER IN THE NORTH. NAM IS STILL TRYING TO SHOW SOME SORT OF MCS MOVING ACROSS OUR AREA LATER TONIGHT. IT HAS BEEN TRENDING FARTHER NORTH WITH THIS AND WOULD THINK IF ANYTHING WERE TO DEVELOP...IT WOULD MAINLY AFFECT OUR FAR NORTHERN FA. AT ANY RATE...WILL KEEP A 20 POP GOING THROUGH THE REST OF THE NIGHT. AREA WELL INTO THE WARM SECTOR ON FRIDAY AND WITH 850 TEMPS UP INTO THE LOWER 20S CELSIUS...EXPECT TO SEE SURFACE TEMPS UP INTO THE LOWER 90S. BOTH THE NAM AND GFS INDICATING RELATIVELY HIGH DEWPOINTS THROUGH THE AFTERNOON..UP INTO THE UPPER 70S. THIS APPEARS OVERDONE BUT STILL EXPECT TO SEE DEWPOINTS INTO THE LOWER TO POSSIBLY MID 70S WHICH WOULD STILL RESULT IN MODERATE INSTABILITIES. FORCING APPEARS TO BE THE LIMITING FACTOR AS THE WARM FRONT WILL BE TO OUR NORTH BUT WITH THE POSSIBILITY OF SOME RESIDUAL BOUNDARIES FROM THE ACTIVITY THIS AFTERNOON...WILL CARRY 20 TO 30 POPS FOR MAINLY AFTERNOON AND EARLY EVENING. FAIRLY GOOD WIND FIELDS IN PLACE FRIDAY AFTERNOON... PARTICULARLY ACROSS THE NORTH AS 40 TO 50 KNOT 5H JET FORECAST TO PUSH ACROSS LOWER GREAT LAKES. IF THUNDERSTORMS DO DEVELOP...SEVERE THREAT WILL LIKELY EXIST...ESPECIALLY ACROSS OUR NORTH. && .LONG TERM (SATURDAY THROUGH THURSDAY)... WARM FRONT PROGGED TO SWING THROUGH FCST AREA OVERNIGHT FRI WITH AN APPROACHING COLD FRONT FROM THE MIDWEST DURING THE DAY SAT. 6Z NAM WAS DRY WITH COLD FROPA...BUT CHANCE POPS ARE WARRANTED AT A MINIMUM. BY SUN MORN...CDFNT IS WELL SE OF OH AND FCST AREA WITH DRY CONDITIONS THROUGH NEXT THURS AS HIGH PRESSURE PASSES N OF FCST AREA AND FILTERS IN DRY AIR ON N WINDS. WINDS SLOWLY TURN S BY THURS...AS RETURN FLOW SETS UP WITH THE HIGH TO THE EAST AND ANOTHER COLD FRONT DRAPED N-S OVER THE MIDWEST AND GREAT PLAINS REGION. MON AND TUES NIGHT APPEAR TO BE EXCELLENT RADIATIONAL COOLING NIGHTS AND DEPENDING ON HOW DRY THE AIRMASS IS COULD BE A BIT COOLER THAN FORECAST. BELIEVE THAT DAYTIME TEMPS MAY BE ON THE COOL SIDE TUES AND WED AS A DRIER AIRMASS WOULD QUICKLY HEAT UP. FRANKS && .AVIATION (18Z-18Z)... SCATTERED SHOWERS ALONG WITH SOME THUNDER HAS REDEVELOPED ACROSS THE SOUTHERN PART OF THE AREA. EXPECT THIS ACTIVITY TO AFFECT THE TAF SITES OVER THE NEXT SEVERAL HOURS. IN ADDITION A LINE OF THUNDERSTORMS ABOUT TO ENTER NORTHWEST INDIANA IS EXPECT TO CONTINUE INTO NORTHERN OHIO. THE SOUTHERN END OF THIS LINE MAY IMPACT DAYTON AND COLUMBUS TERMINALS LATE THIS AFTERNOON OR EVENING. ONCE THIS ALL MOVES THROUGH CLOUDS SHOULD DIMINISH ALTHOUGH THERE WILL BE SOME VISIBILITY RESTRICTIONS IN MIST/HAZE OVERNIGHT. THERE IS SOME POTENTIAL FOR LATE NIGHT CONVECTION MAINLY FOR NORTHERN TAF SITES BUT PROBABILITY IS TOO LOW TO INCLUDE ANYTHING MORE THAN VCSH. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...NONE. KY...NONE. IN...NONE. &&
