NWS Wilmington, OH wrote its last area forecast discussion before the first event at Aug 26, 3:04 PM EST, 48 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON OH 404 PM EDT TUE AUG 26 2014 .SYNOPSIS... A WEAK COLD FRONT WILL CROSS SOUTHEAST THROUGH THE OHIO VALLEY OVERNIGHT AND EARLY WEDNESDAY. HIGH PRESSURE BUILDING IN THE GREAT LAKES WEDNESDAY WILL SETTLE OVER THE NORTHERN OHIO VALLEY THURSDAY. AS THE HIGH EXITS TO THE EAST...SOUTHERLY FLOW WILL SET UP FOR FRIDAY AND BRING A RETURN TO HUMID CONDITIONS ACROSS THE REGION. && .NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/... ISOLATED SHOWERS ARE POSSIBLE OVER WESTERN CWA THIS EVENING BUT WILL BE MORE LIMITED TO THE NORTHWEST WHERE A LINE OF CONVECTION IS EXPECTED TO WEAKEN AS IT BUTTS INTO THE ESTABLISHED HIGH PRESSURE OVER THE CWA. THE FOCUS OF THESE STORMS WILL LIFT NORTHEAST AND OUT OF CWA...BUT THE LINGERING COLD FRONT SHOULD PROVIDE A FOCUS FOR ISOLATED CONVECTION THROUGH THE EVENING AND OVERNIGHT HOURS. LOWS TONIGHT WILL DIP INTO THE UPPER 60S IN MOST AREAS. SHOWERS APPEAR TO HAVE A BETTER CHANCE OVER NORTHERN CWA OVERNIGHT BUT THE THREAT WILL CONTINUE TO PUSH SOUTH THROUGH DAYBREAK AND AFFECT ALL BUT FAR SOUTHEASTERN CWA WITH AT LEAST AN ISOLATED THREAT FOR THUNDERSTORMS. && .SHORT TERM /6 AM WEDNESDAY MORNING THROUGH THURSDAY NIGHT/... THE COLD FRONT MOVING THROUGH CWA EARLY WEDNESDAY IS IN A RELATIVELY RECEPTIVE YET NOT OVERLY SUPPORTIVE ATMOSPHERE. I EXPECT THAT SCATTERED TO ISOLATED CONVECTION WILL DEVELOP AND MOVE E-SE AS THE HIGH BUILDS AND WINDS SHIFT NW TO N. SOME AFTERNOON RE-DEVELOPMENT MAY OCCUR IF ENOUGH SUN CAN PERCOLATE SOUTHERN CWA TOWARDS A CONVECTIVE TEMPERATURE. ANY STORMS THAT DEVELOP TOMORROW WILL MOVE SOUTH AND REMAIN OUT OF OHIO THROUGH EARLY FRIDAY. NORTHEAST WINDS AS THE HIGH NORTH OF THE AREA MOVES EAST WILL INHIBIT STORM DEVELOPMENT WITH A DRYING LOWER ATMOSPHERE. WHILE CHANCES OF THUNDERSTORMS ON THURSDAY ARE MARGINAL...THEY ARE SQUARELY FOCUSED OVER KENTUCKY WITH THE HIGH PUSHING THE FOCUS SOUTHWARD. WHILE I BELIEVE THE RETURN FLOW OF MOISTURE WILL NOT BRING ANY THREAT FOR CONVECTION OVERNIGHT THURSDAY...I COULD NOT RULE OUT SOMETHING WORKING INTO WESTERN PORTIONS OF CWA AND KEPT AN ISOLATED POP IN OVERNIGHT. TEMPERATURES WILL COOL INTO THE LOWER 60S FOR MOST AREAS OVERNIGHT. ONE EXCEPTION IS OVER KY AND W OF METRO CINCY WHERE UPPER 60S WILL HOLD TOUGH WITH THE MORE MOIST AIR DOES NOT GET BOOTED OUT BY THE HIGH PRESSURE. DO NOT THINK THAT LOWER 90S AND SOMEWHAT HIGH HUMIDITY OVER METRO CINCY AND SOUTHERN CWA MERITS ANY HAZARDS IN THE OUTLOOK. && .LONG TERM /FRIDAY THROUGH TUESDAY/... HAVE TAKEN A BLEND OF THE ECMWF...CMC...AND GFS THROUGH SATURDAY. THEREAFTER...HAVE SIDED WITH A SLIGHTLY FASTER SOLUTION FOR MAIN MID LEVEL TROUGH FOR THE LATTER HALF OF THE WEEKEND PER A GFS/CMC BLEND. FORMER FRONTAL BOUNDARY WILL HEAD SLOWLY NORTHEAST ACROSS THE REGION FRIDAY INTO FRIDAY NIGHT AS WARM FRONT DUE TO MID LEVEL RIDGING DOWNSTREAM FROM A MID LEVEL TROUGH OVER THE CENTRAL PLAINS. HAVE KEPT A 30 PERCENT CHANCE OF SHOWERS AND THUNDERSTORMS WITH THIS BOUNDARY. FOR SATURDAY INTO SUNDAY...MID LEVEL TROUGH AND EMBEDDED S/WV ENERGY WILL SHEAR SOME AS THEY HEAD NORTHEAST INTO THE GREAT LAKES. A COLD FRONT WILL ALSO PUSH SLOWLY SOUTHEAST TOWARD THE REGION FROM THE NORTHWEST. INCREASING MOISTURE WITH GENERALLY WEAK TO MODERATE FORCING WILL BRING AN INCREASING CHANCE OF SHOWERS AND STORMS SATURDAY NIGHT INTO SUNDAY. FOR SUNDAY NIGHT INTO MONDAY...AFOREMENTIONED ENERGY CONTINUES TO PIVOT AND SHEAR AS IT MOVES NORTHEAST TOWARD NEW ENGLAND. MEANWHILE...FRONTAL BOUNDARY STALLS JUST TO OUR NORTHWEST AS IT BECOMES PARALLEL TO MID LEVEL SOUTHWESTERLY FLOW. PCPN CHANCES WILL DECREASE SUNDAY NIGHT FROM WEST TO EAST...WITH A CHANCE OF MAINLY DIURNAL SHOWERS AND STORMS ON MONDAY. ELONGATED MID LEVEL RIDGE MAY BECOME QUASI-STATIONARY...EXTENDING FROM OFF THE MID ATLANTIC COAST TO THE OHIO VALLEY AND POINTS TO THE SOUTH FROM EARLY TO MID WEEK NEXT WEE. THIS WILL KEEP AT LEAST A CHANCE OF SHOWERS/STORMS GOING WITH THE DIURNAL CYCLE BEING MOST FAVORED. SUMMER TEMPERATURES CAN BE EXPECTED INTO THE FIRST PART OF THE WEEKEND WITH A LITTLE BIT OF A COOL DOWN ON SUNDAY DUE TO CLOUDS AND PCPN. TEMPERATURES WILL RETURN TO THE UPPER 80S TO AROUND 90 FOR THE BEGINNING OF NEXT WEEK AS WARM/MOIST AIR CIRCULATES AROUND ELONGATED MID LEVEL RIDGE. && .AVIATION /20Z TUESDAY THROUGH SUNDAY/... H5 RIDGE WILL FATTEN SOME DURING THE NEXT 24 HOURS AS S/W SWINGS FROM THE PLAINS ACROSS THE SRN GREAT LAKES. A CDFNT WILL SAG DOWN INTO THE REGION TONIGHT. MAJORITY OF THE SYNOPTIC MODELS BRING SOME CONVECTION DOWN THROUGH THE TAFS WITH FROPA. THE FINER RESOLUTION MODELS ARE LESS AMBITIOUS WITH THE STORMS HOWEVER. CARRIED A VCTS AT THE TAFS TO COVER THE THREAT. BEGAN THE VCTS AT DAY AROUND 03Z...THEN FINALLY AT CVG/LUK BY 08Z. BY 12Z THE FRONT SHOULD BE IN SRN OHIO. ENDED THE VCTS MENTION AT THE NRN TAFS ABOUT THIS TIME. WITH THE FRONT HANGING AROUND THE SRN TAFS AND THE MODELS PRODUCING PLENTY OF CAPE ON WEDNESDAY...KEPT THE VCTS GOING THRU THE END OF THE TAF PERIOD. OUTLOOK...SCATTERED THUNDERSTORMS POSSIBLE ON SATURDAY AND SUNDAY. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...NONE. KY...NONE.
