AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON OH 158 PM EDT THU JUL 20 2006 .AVIATION /18Z-18Z/... CONVECTION IS DEVELOPING ACROSS CENTRAL OHIO ALONG OUTFLOW BOUNDARY AHD OF WEAKENING MCS. CAP IS MINIMAL ACRS CENTRAL OHIO WITH BNDRY LAYER CAPES APPROACHING 2500 J/KG. CAP AROUND 100 J/KG IS INHIBITING CONVECTIVE DEVELOPMENT ACRS SW OHIO. AFTER THE PASSAGE OF THIS OUTFLOW BNDRY EXPECT COLD POOL PRECIP ACRS INDIANA TO AFFECT THE WESTERN TAF SITES. THIS PRECIP WL HELP STABILIZE THE AIRMASS INHIBITING ADDITIONAL TSTM DEVELOPMENT UNTIL COLD FRONT APPROACHES LATER THIS EVENING. HAVE LIMITED TSTM MENTION TO 4 HOURS WITH FROPA AND THEN BRING IN SOME MVFR CIGS IN LOW LEVEL CAA PATTERN BEHIND THE FRONT. && .PREV DISCUSSION... /ISSUED 1122 AM EDT THU JUL 20 2006/ SHORT TERM /REST OF TODAY/... ACTIVE ZONE FOR CONVECTION AROUND UPPER LEVEL RIDGE OVER THE NATIONS MID SECTION. MESOSCALE CONVECTIVE COMPLEX WHICH DEVELOPED LAST NIGHT IN THE UPPER MS VLY AROUND THE PERIPHERY OF THIS RIDGE HAS DROPPED SE THRU INDIANA AND ILLINOIS TOWARD BEST INSTBY AND WEAKENED. ILN 12Z SOUNDING SHOWS WARM AIR BTWEEN 850MB AND 700MB. THIS CAP IS INHIBITING THE DEVELOPMENT OF WIDESPREAD CONVECTION. EXPECT CURRENT TRENDS TO CONTINUE WITH AFOREMENTIONED MCS STAYING MAINLY WEST OF FA WITH NEW CONVECTIVE DEVELOPMENT INTO WEST CENTRAL OHIO THIS AFTERNOON WHERE BEST LO LVL CONVERGENCE IS EXPECTED. AS CAP DIMINISHES AND BETTER FORCING COMES INTO PLAY WITH THE APPROACH OF A COLD FRONT EXPECT THESE STORMS TO DEVELOP SE ACRS FA. CURRENT FORECAST HAD VERY GOOD HANDLE ON PRECIP TIMING. HAVE ADDED MENTION OF POSSIBLE SEVERE STORMS THIS AFTN/EVENING WITH DAMAGING WINDS BEING THE MAIN THREAT. PREV DISCUSSION... /ISSUED 648 AM EDT THU JUL 20 2006/ AVIATION /12Z-12Z/... THUNDERSTORM COMPLEX TO THE NORTHWEST OF THE REGION IS EXPECTED TO WEAKEN BEFORE REACHING THE TAF SITES LEAVING ONLY REMNANT CLOUD COVER. MVFR VISIBILITIES AT MOST LOCATIONS WILL GRADUALLY IMPROVE THROUGH THE MORNING. STILL APPEARS THAT BEST CHANCE FOR AFTERNOON THUNDERSTORMS WILL BE NEAR THE COLUMBUS TERMINALS. THEN OVERNIGHT EXPECT A PRETTY GOOD CHANCE AT ALL SITES AS A COLD FRONT MOVES INTO THE REGION. HAVE LIMITED THUNDER TO A 3 TO 4 HOUR WINDOW WHEN THE CHANCE LOOKS HIGHEST. BUT THIS MAY WELL NEED TO BE ADJUSTED IN LATER FORECASTS. OUTSIDE OF THUNDERSTORMS IT APPEARS THAT THERE WILL ONCE AGAIN BE SOME VISIBILITY RESTRICTIONS AFTER DARK IN HAZE/MIST. PREV DISCUSSION... /ISSUED 358 AM EDT THU JUL 20 2006/ SHORT TERM /TODAY THROUGH SATURDAY/... A FRONTAL BNDRY STRETCHED FROM JUST SOUTH OF CHICAGO THROUGH INDIANA AND INTO WEST VA THIS MORNING. SKIES WERE GENERALLY CLEAR ACROSS EASTERN OHIO AND NE KY WITH MAINLY HIGH CLOUDS ENCROACHING INTO INDIANA AND WESTERN OHIO. AN MCS WAS PUSHING THROUGH WI AND IOWA. TEMPERATURES GENERALLY RANGED FROM THE MID TO LOWER 70S. FOR TODAY...THE GFS AND NAM ARE IN CONSIDERABLE DISAGREEMENT ABOUT THUNDERSTORM TIMING AND COVERAGE IN ADVANCE OF AN APPROACHING FRONTAL BNDRY AND S/W. THE GFS SHOWS MORE EXTENSIVE DEVELOPMENT ACROSS THE WHOLE FCST AREA AS THE FRONT SLIDES SOUTH OVERNIGHT...WHILE THE NAM SUGGESTS THAT NORTHERN AND CENTRAL OHIO WILL BEAR NEARLY THE SOLE BRUNT OF THE EVENT. AS ONE WOULD EXPECT...MAV POPS ARE GENERALLY MUCH HIGHER THAN MET POPS. GIVEN THE CONSIDERABLE UNCERTAINTY...HIGH CHANCE POPS NW TO SE FROM LATE MORNING INTO THE OVERNIGHT STILL SEEMS REASONABLE AT THIS POINT. LOOKING AT SEVERE PARAMETERS FROM FCST SNDGS...THE GFS STILL SEEMS UNREASONABLY COOL. EVEN SO...ANY THUNDERSTORMS THAT DEVELOP COULD BECOME SEVERE WITH DAMAGING WINDS BEING THE MAIN THREAT. HIGH TEMPS WILL BE GREATLY DEPENDANT ON CLOUD COVER/PCPN ONSET IN THE NW...WITH LOWER 90S POSSIBLE IN THE SOUTH AND EAST. ALTHOUGH HEAT INDICES TODAY WILL REACH INTO THE MID/UPPER 90S AT SOME LOCATIONS IN THE SOUTHERN HALF OF OUR CWA...THIS STILL BELOW ADVISORY CRITERIA. FOR FRIDAY AND SATURDAY...THERE ARE STILL A LOT OF MODEL DIFFERENCES WITH RESPECT TO PCPN CHANCES...BUT HIGH TEMPS WILL BE MORE SEASONABLE IN NORTHERLY FLOW BEHIND THE FRONT. THERE WILL BE SOME LINGERING INSTABILITY AS UPPER DISTURBANCES PASS OVER THE AREA...WITH THE CHANCE OF SHOWERS AND THUNDERSTORMS GREATER IN THE SOUTHERN FCST AREA. PREV DISCUSSION... /ISSUED 332 PM EDT WED JUL 19 2006/ LONG TERM /FRIDAY THROUGH WEDNESDAY/... COLD FRONT FORECAST TO PUSH SOUTH OF FA THROUGH THE DAY ON FRIDAY. AS IT DOES..WILL LIKELY SEE SOME LINGERING SHOWER AND THUNDERSTORM ACTIVITY ACROSS THE SOUTH. THE 19/00Z ECMWF APPEARS TO BE PUSHING THE FRONT FURTHER TO OUR SOUTH THROUGH THE WEEKEND AND DRYING US OUT. HOWEVER...THE 19/12Z GFS IS STILL TRYING TO SLOW THINGS UP AND BRING A WAVE ALONG THE FRONT FRIDAY NIGHT INTO SATURDAY. WILL BACK OFF ON POPS A BIT THROUGH THIS TIME FRAME BUT FOR CONSISTENCY PURPOSES...WILL STILL MAINTAIN A CHANCE OF THUNDERSTORMS ACROSS THE SOUTH THROUGH SATURDAY NIGHT. HIGH PRESSURE SHOULD THEN BUILD INTO THE REGION THROUGH THE EARLY PART OF NEXT WEEK SO WILL KEEP IT RELATIVELY DRY THROUGH THE REST OF THE EXTENDED. WITH COOLER AIRMASS FILTERING IN BEHIND FRONT...SHOULD SEE A RETURN TO MORE SEASONABLE TEMPERATURES THROUGH THE LONG TERM PERIOD. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...NONE. KY...NONE. IN...NONE. &&
