NWS Wilmington, OH wrote its last area forecast discussion before the first event at Jun 4, 9:09 AM EST, 41 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON OH 1009 AM EDT WED JUN 4 2014 .SYNOPSIS... A WARM FRONT AND UPPER LEVEL DISTURBANCE WILL BRING WIDESPREAD THUNDERSTORM ACTIVITY TO THE REGION TODAY...ENDING LATE THIS EVENING. A COLD FRONT WITH HIGH PRESSURE BUILDING INTO THE REGION BEHIND IT WILL BRING A DRY AND COOL AIRMASS TO THE AREA THURSDAY THROUGH SATURDAY. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... IR SATELLITE IMAGES INDICATING WARMING CLOUD TOPS WITH DECAYING MCS CURRENTLY PUSHING ACROSS SOUTHWEST OHIO AND NORTHERN KENTUCKY. WE CONTINUE TO GET A FEW REPORTS OF PEA SIZE HAIL WITH THE STRONGER STORMS...BUT OVERALL THERE HAS BEEN A GENERAL WEAKENING TREND IN THE REFLECTIVITY ON RADAR OVER THE PAST HOUR. BASED ON SURFACE DEWPOINTS...WARM FRONT APPEARS TO BE SITUATED FROM CENTRAL INDIANA INTO FAR SOUTHWEST OHIO ATTM AND THIS LOOSELY CORRELATES WITH A SECONDARY LINE OF CONVECTION NOT NECESSARILY ASSOCIATED WITH THE MCS REMNANTS. STILL SOME UNCERTAINTY TO WHAT EFFECTS THE DECAYING MCS WILL HAVE ON THE WARM FRONT AS THE RAIN COOLED AIR TO THE NORTH MAY DELAY THE NORTHWARD PUSH OF THE WARM FRONT HEADING INTO THIS AFTERNOON. THE OTHER CONCERN IS THE AMOUNT OF DEBRIS CLOUDS THAT WILL LINGER ACROSS THE AREA AT LEAST INTO EARLY AFTERNOON AND THEIR AFFECT ON SOLAR INSOLATION. BOTH THE 12Z NAM AND LATEST RAP ARE KEEPING THE BETTER ML CAPES...IN EXCESS OF 1000 J/KG...GENERALLY ALONG AND SOUTH OF THE OHIO RIVER THROUGH THIS AFTERNOON. HOWEVER...BETTER JET DYNAMICS WILL BE PIVOTING INTO OUR ARE THROUGH THE AFTERNOON HOURS AND THIS WILL LIKELY HELP COMPENSATE FOR SOME OF THE LOWER INSTABILITIES. MOST OF THE HIGHER RES MODELS ARE SUGGESTING REDEVELOPMENT THIS AFTERNOON ALONG THE BOUNDARY WITH IT THEN PUSHING SOUTH LATE THIS AFTERNOON INTO EARLY EVENING. GIVEN THE CURRENT SET UP...THINK THE BEST CHANCE FOR THIS REDEVELOPMENT WILL BE ACROSS ABOUT THE SOUTHERN THIRD OF OUR FA. IF THIS OCCURS...SHEAR PROFILES WILL BECOME FAVORABLE FOR ORGANIZED STORMS AND AN ASSOCIATED SEVERE THREAT FROM MID AFTERNOON INTO EARLY EVENING. GIVEN THE INCREASING JET...THINK THE PRIMARY SEVERE THREAT WILL BE DAMAGING WINDS...BUT IF WE ARE ABLE TO GET SOME BETTER INSTABILITIES INTO THE AREA...ROTATING STORMS AND LARGE HAIL WILL BECOME MORE OF A THREAT GIVEN THE SHEAR PROFILES. THE OTHER CONCERN WILL BE LOCALLY HEAVY RAIN. PWS WILL PUSH UP INTO THE 150 PERCENT OF NORMAL RANGE THROUGH THIS AFTERNOON SO HEAVY RAIN WILL BE POSSIBLE WITH THE STRONGER STORMS. WHILE THE HI RES MODELS DISAGREE WITH EXACTLY WHERE THE AFTERNOON DEVELOPMENT WILL OCCUR...THEY ARE ALL FAIRLY CONSISTENT WITH PUSHING ANY DEVELOPMENT FAIRLY QUICKLY SOUTHWARD ONCE IT DEVELOPS SO HAVE OPTED TO HOLD OFF ON A FLASH FLOOD WATCH ATTM. && .SHORT TERM /6 PM THIS EVENING THROUGH FRIDAY NIGHT/... ONGOING STORMS OVER MUCH OF THE CWA THIS EVENING WILL MOVE EAST WITH THE SURFACE LOW IN THE MEAN WESTERLY FLOW ALOFT...AND SOUTH AS HIGH PRESSURE BUILDS IN THE GREAT LAKES REGION. A FAIRLY RAPID TURNOFF WILL OCCUR OVERNIGHT. EVENING SHOWERS COULD PERSIST THAT FLOODING COULD BE A CONCERN THROUGH ABOUT MIDNIGHT. THE HIGH PRESSURE WILL STRENGTHEN ON THURSDAY AND HELP CONTINUE TO PUSH DRIER AIR OVER THE OHIO VALLEY. TEMPERATURES WILL BE IN THE 70S THURSDAY AND FRIDAY...WITH OVERNIGHT LOWS DROPPING IN TO THE 50S FOR MOST AREAS. && .LONG TERM /SATURDAY THROUGH TUESDAY/... FOR FRIDAY NIGHT INTO SATURDAY...HIGH PRESSURE WILL MOVE OFF TO THE EAST WHILE ONE OF THOSE UPPER LEVEL DISTURBANCES MOVES TOWARD THE GREAT LAKES. WE SHOULD SEE ONE MORE DRY DAY WITH TEMPERATURES WARMING INTO THE LOWER AND MID 80S. FOR THE PERIOD SATURDAY NIGHT INTO SUNDAY...INCREASING MOISTURE...LIFT AND THE APPROACH OF A WARM FRONT/COLD FROM TANDEM WILL BRING A CHANCE OF SHOWERS AND STORMS TO OUR AREA. HAVE KEPT POPS AT 50 PERCENT FOR NOW DUE TO SOME TIMING ISSUES. FOR SUNDAY NIGHT INTO MONDAY...UPPER LEVEL DISTURBANCE AND COLD FRONT SHOULD PUSH EAST THROUGH THE REGION WITH PCPN COMING TO AN END BY MONDAY MORNING. DRIER AIR AND A LITTLE COOLER TEMPERATURES CAN BE EXPECTED BY MONDAY. HIGH PRESSURE IS FORECAST TO BUILD BRIEFLY BACK INTO THE REGION MONDAY NIGHT INTO TUESDAY. TEMPERATURES WILL BE NEAR TO SLIGHTLY BELOW SEASONAL NORMALS. && .AVIATION /14Z WEDNESDAY THROUGH SUNDAY/... MVFR TO LIFR FOG IS AFFECTING THE SRN TAFS WHERE THE DEWPOINTS REMAINED IN THE LOWER TO MID 60S OVERNIGHT. THE FOG SHOULD BREAK UP QUICKLY AS SUNSHINE BEGINS THE MIXING PROCESS. THUNDERSTORM COMPLEX ACROSS INDIANA HAS A MAINLY EASTERLY COMPONENT. LATEST TIMING HAS IT REACHING THE WRN TAFS IN THE 13 -14Z TIME FRAME. EXPECT A COUPLE OF HOURS OF TS AT THE TAFS. ADDITIONAL DEVELOPMENT IS EXPECTED DURING THE AFTERNOON. SOME OF THE THUNDERSTORMS IN THE AFTERNOON COULD POSSIBLY BE SEVERE. A LOW PRESSURE CENTER WILL RACE E TONIGHT FINALLY DRAGGING THE FRONT THRU THE TAFS WHILE BRINGING AN END TO THE THUNDERSTORMS. MVFR CIGS ARE EXPECTED TO DEVELOP POST FRONTAL TONIGHT.
