NWS Wilmington, OH wrote its last area forecast discussion before the first event at Jun 25, 9:23 PM EST, 3 hours 37 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON OH 1023 PM EDT WED JUN 25 2008 .SYNOPSIS... A MOIST AND UNSTABLE AIRMASS WILL REMAIN ACROSS THE REGION THROUGH THE END OF THE WEEK. AS WEAK DISTURBANCES MOVE ACROSS THE AREA...SHOWERS AND THUNDERSTORMS WILL OCCUR. A STRONGER UPPER LEVEL SYSTEM AND ASSOCIATED COLD FRONT WILL PUSH INTO THE GREAT LAKES AND OHIO VALLEY OVER THE WEEKEND. && .NEAR TERM /UNTIL 6 AM THURSDAY MORNING/... STORMS THAT HAD BEEN TRAINING ACROSS PARTS OF WEST CENTRAL OHIO HAVE STARTED TO BECOME PROGRESSIVE. HAVE SPREAD HIGH POPS INTO CENTRAL OHIO GENERALLY ALONG AND NORTH OF I-70. SOME QUESTION ON WHETHER DEVELOPMENT WILL OCCUR FURTHER SOUTH ALTHOUGH HAVE NOTED A CELL IN SOUTH CENTRAL INDIANA. AT THIS POINT THE CHANCE OF RAIN APPEARS LOW IN THE SOUTHERN HALF OF THE FORECAST AREA. ONLY MADE MINOR ADJUSTMENTS TO TEMPERATURES AND WINDS TO BLEND LATEST OBSERVATIONS INTO THE FORECAST. && .SHORT TERM /6 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/... EXPECT A LULL IN ACTIVITY THURSDAY MORNING WITH ADDITIONAL STORMS DEVELOPING LATER IN THE DAY AS HEATING BRINGS FURTHER DESTABILIZATION. SHOWERS AND THUNDERSTORMS WILL CONTINUE INTO THE EVENING. DIFFICULT TO DETERMINE WHETHER THERE WILL BE SUPPORT SUSTAINING ACTIVITY THROUGH THE NIGHT BUT GIVEN UNCERTAINTIES JUST KEPT CHANCE POPS GOING. BELIEVE GFS MOS IS SLIGHTLY TOO WARM WITH HIGH TEMPERATURES BUT LOOKED REASONABLE FOR LOWS. && .LONG TERM /FRIDAY THROUGH WEDNESDAY/... FOR FRIDAY...SCT STORMS ASSOCIATED WITH AN UPPER DISTURBANCE WILL DEVELOP IN ADVANCE OF AN APPROACHING COLD FRONT. HIGH TEMPERATURES WILL MAINLY BE IN THE UPPER 80S...HIGHLY DEPENDANT ON PCPN TIMING. SATURDAY...THE MODELS ARE IN GENERAL AGREEMENT WITH SLOWER TIMING WITH THE COLD FRONT. THE SCT/NUMEROUS PCPN COVERAGE WILL LIKELY LINGER INTO SUNDAY MORNING. AGAIN...HIGH TEMPERATURES WILL BE HELD BACK BY THE RAIN SATURDAY...WITH SEASONABLY COOL AIR SETTLING IN BEHIND THE FRONT ON SUNDAY. A TRAILING UPPER TROF WILL LINGER SCT SHOWERS/STORMS INTO MONDAY...WITH SEASONABLY COOL TEMPERATURES PERSISTING. THEN...HIGH PRESSURE BUILDS AND MOVES EAST OF THE REGION THROUGH WEDNESDAY...WITH A SLIGHT WARMING TREND. && .AVIATION /02Z THURSDAY THROUGH MONDAY/... SHOWERS AND THUNDERSTORMS OVER THE COLUMBUS METRO WILL CLEAR THE TERMINALS BY 00Z OR SHORTLY THEREAFTER. SKIES ARE CLEARING BEHIND THIS AREA OF CONVECTION WITH JUST SCATTERED MID/HIGH CLOUDS. THE BIG QUESTION IS IF CONVECTION WILL REDEVELOP ALONG A CONVERGENT TROUGH ACROSS CENTRAL OHIO OVERNIGHT...AS SUGGESTED BY THE MODELS. SATELLITE IMAGERY SHOWS SUBSIDENCE ACROSS KY/IN BEHIND THIS INITIAL WAVE...AND THINK THIS MAY ACT AGAINST WIDESPREAD CONVECTIVE REDEVELOPMENT OVERNIGHT. BEST CHANCE TO SEE CONVECTION...IF IT DOES REDEVELOP...WILL BE KCMH/KLCK...BUT ONLY HANDLED WITH A VCSH AND CB OVERNIGHT DUE TO THE UNCERTAINTY. FOR THURSDAY...AIRMASS WILL DESTABILIZE BY AFTERNOON AND FAVOR MORE SCATTERED SHOWERS AND STORMS. HOWEVER...FORCING WILL BE WEAK SO COVERAGE IS NOT EXPECTED TO BE WIDESPREAD. THEREFORE IT IS TOO EARLY WARRANT ANY MENTION OF SHRA/TSRA AT ANY ONE TERMINAL AT THIS POINT. OUTLOOK...THUNDERSTORMS POSSIBLE THURSDAY NIGHT THROUGH SUNDAY. && .ILN WATCHES/WARNINGS/ADVISORIES...
