NWS Wilmington, OH wrote its last area forecast discussion before the first event at Jun 19, 1:02 PM EST, 1 hour 28 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON OH 202 PM EDT THU JUN 19 2014 .SYNOPSIS... A SLOW MOVING FRONTAL BOUNDARY INTERACTING WITH A VERY MOIST AND UNSTABLE AIRMASS WILL BRING THE LIKELIHOOD FOR SHOWERS AND THUNDERSTORMS TODAY THROUGH FRIDAY. DRIER WEATHER IS EXPECTED FOR SATURDAY AND SUNDAY WHEN SURFACE HIGH PRESSURE IS FORECAST TO TRAVEL ACROSS THE GREAT LAKES AND OHIO VALLEY ON A NORTHWEST FLOW ALOFT. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... SOME SCATTERED CONVECTION CONTINUES TO DROP SOUTHEAST THROUGH THE WHITEWATER AND MIAMI VALLEYS. SFC BOUNDARY THAT THE CONVECTION IS ASSOCIATED WITH IS FORECAST TO CONTINUE TO SAG SOUTH TODAY TO NEAR THE OHIO RIVER. ACTIVITY SHOULD BECOME MORE NUMEROUS IN THE SOUTH THIS AFTERNOON...WITH THE NORTHEAST DRYING OUT. ADJUSTED POPS ACCORDINGLY. TEMPERATURES WILL BE SOMEWHAT COOLER TODAY DUE TO CLOUD COVER AND PRECIPITATION...WITH HIGHS FORECAST TO BE IN THE 80S. && .SHORT TERM /6 PM THIS EVENING THROUGH SATURDAY/... WITH THE FRONT NEAR THE OHIO RIVER...THE CHANCE OF THUNDERSTORMS WILL PERSIST TONIGHT...MAINLY IN SOUTHERN COUNTIES. EXPECT NUMEROUS THUNDERSTORMS FRIDAY WHEN CONVECTION WILL BE ENHANCED BY A STRONG SHORT WAVE TRAVELING ALONG THE FRONT...COINCIDING WITH DAYTIME HEATING AND INSTABILITY. A DRIER PATTERN WILL BEGIN ON SATURDAY WHEN A RIDGE OF HIGH PRESSURE IS FORECAST TO BUILD IN ON A NORTHWEST FLOW ALOFT. HOWEVER...THERE WILL STILL BE A SLIGHT CHANCE FOR SHOWERS AND THUNDERSTORMS TO DEVELOP IN RESIDUAL MOISTURE AND INSTABILITY...MAINLY OVER SOUTHEASTERN LOCATIONS. LOOK FOR NEAR NORMAL HIGHS IN THE 80S BOTH FRIDAY AND SATURDAY. && .LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/... THE PATTERN THROUGH THE EXTENDED FORECAST PERIOD WILL BE CHARACTERIZED BY WEAK RIDGING OVER THE SOUTH CENTRAL STATES...GRADUALLY FLATTENING BY EARLY NEXT WEEK. THE OHIO VALLEY WILL BE ON THE NORTHERN PERIPHERY OF THIS RIDGE...WITH A GENERALLY ILL-DEFINED SURFACE PRESSURE PATTERN UNDERNEATH. BY THE MIDDLE OF THE WEEK...12Z MODEL RUNS SUGGEST THAT A SHORTWAVE TROUGH WILL BE MOVING ACROSS THE REGION IN THE GENERALLY ZONAL FLOW. THE AIR MASS IS NOT EXPECTED TO CHANGE VERY MARKEDLY...LEADING TO SIMILAR MAX AND MIN TEMPERATURES THROUGH THE PERIOD. THE MOIST AND UNSTABLE CONDITIONS WILL ALSO LEAD TO CONTINUED CHANCES FOR (GENERALLY DIURNAL) SHOWERS AND THUNDERSTORMS. THOUGH LOW OVER THE WEEKEND (WITH THE ECMWF SUGGESTING DRY CONDITIONS)...THESE CHANCES ARE EXPECTED TO INCREASE GOING INTO THE NEW WEEK...AS THE PATTERN SHIFTS JUST ENOUGH THAT DISTURBANCES IN THE FLATTENING MID-LEVEL FLOW WILL BE CAPABLE OF MOVING THROUGH THE AREA. THOUGH THE 12Z RUNS DO SHOW SUCH A DISTURBANCE FOR WEDNESDAY IN THE GENERAL AREA...THIS FEATURE IS NOT YET BEING MODELED CONSISTENTLY. HOWEVER...IT CAN BE VIEWED AS AN EXAMPLE SCENARIO FOR THE POTENTIAL OF ORGANIZED CONVECTION AT SOME POINT LATE IN THE FORECAST PERIOD. && .AVIATION /18Z THURSDAY THROUGH TUESDAY/... CONVECTION IS BEGINNING TO FIRE AGAIN AS THE CONVECTIVE TEMPERATURE IS REACHED. BEST COVERAGE WILL BE AROUND THE SLOW MOVING SFC BOUNDARY IN SRN OHIO. SCT TSTM WILL AFFECT THE SRN/WRN TAFS THROUGH THE AFTN HOURS. ACTIVITY BEGINS TO SETTLE DOWN AROUND 00Z...BUT THERE COULD BE LINGERING CONVECTION OVERNIGHT. MOISTURE LOW LEVELS AND LIGHT WINDS WILL ALLOW FOR MAINLY MVFR FOG DEVELOPMENT LATER TONIGHT. SFC LOW WILL PUSH EAST INTO THE REGION ON FRIDAY...MOVING THE FRONT BACK NE. ADDITIONAL THUNDERSTORMS WILL DEVELOP ON THE DAY FRIDAY. OUTLOOK...THUNDERSTORMS LIKELY FRIDAY AFTERNOON AND AGAIN ON TUESDAY. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...NONE. KY...NONE.
