The episode as NWS ILN wrote it up.
Heavy rain fell across west central and central Ohio and the Miami Valley ahead of a cold front.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Wilmington, OH wrote its last area forecast discussion before the first event at Mar 14, 12:40 AM EST, 1 hour 40 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON OH 140 AM EDT WED MAR 14 2007 .AVIATION /06Z-06Z/... SCATTERED SHOWER ACTIVITY PUSHING EAST NORTHEAST ACROSS SOUTHERN INDIANA AND NORTHERN KENTUCKY EARLY THIS MORNING. THIS SHOULD CONTINUE TO OVERSPREAD OUR FA OVER THE NEXT FEW HOURS AS MID LEVEL SHORT WAVE MOVES EAST ACROSS OHIO VALLEY. TOUGH TO RULE OUT AN ISOLATED LIGHTNING STRIKE BUT WITH ONLY MARGINAL INSTABILITY THROUGH 12Z...WILL NOT INCLUDE ANY THUNDER OR CB. CIGS GENERALLY RUNNING IN THE VFR RANGE SO WILL ALLOW FOR THAT IN THE PREVAILING FCST BUT AS LOW LEVELS MOISTEN UP...WE COULD SEE SOME MVFR CIGS FROM TIME TO TIME THROUGH DAYBREAK. SHOWERS ALSO APPEAR TO BE FAIRLY LIGHT SO WILL KEEP TEMPO VSBY RESTRICTION IN THE MVFR CATEGORY. EXPECT PCPN TO TAPER OFF FAIRLY QUICKLY IN THE 12Z TO 15Z TIME FRAME AS SHORT WAVE ENERGY SHIFTS EAST AND SUBSIDENCE DEVELOPS ACROSS AREA. IN THIS SCENARIO...PREFER DRIER LOOKING NAM SOLUTION THROUGH THE DAYTIME PERIOD AND WOULD NOT BE SURPRISED IF WE END UP SEEING A FAIR AMOUNT OF BREAKS IN THE CIGS. AS WE HEAD THROUGH THE AFTERNOON...THE AIRMASS DOES BEGIN TO DESTABILIZE...PARTICULARLY ACROSS NORTHERN PORTIONS OF FA. WILL THEREFORE ALLOW FOR A VCSH AND CB AT KDAY/KCMH/KLCK FOR LATE AFTERNOON AND INTO EARLY EVENING. THE 00Z GFS HAS SPED UP THE TIMING OF THE FRONT...PUSHING IT SOUTH INTO OUR NORTHERN FA BY 06Z. HOWEVER...THE LATEST NAM AND NGM OUR STILL KEEPING IT MAINLY TO OUR NORTH THROUGH 06Z AND PREFER THIS SLOWER SOLUTION THAT HAS BEEN MORE CONSISTENT. WILL THEREFORE JUST ALLOW FOR A TEMPO GROUP OF SHOWERS ACROSS THE NORTH LATE IN THE TAF PERIOD AND KEEP THE SOUTHERN TAFS DRY THROUGH 06Z. && .PREV DISCUSSIONS... /ISSUED 1018 PM EDT TUE MAR 13 2007/ SHORT TERM /REST OF TONIGHT/... SCATTERED SHOWERS HAVE BEEN DEVELOPING IN WESTERN KENTUCKY AND SOUTHERN ILLINOIS. EXPECT THIS PRECIPITATION TO INCREASE IN COVERAGE AS IT MOVES NORTHEAST INTO THE FORECAST AREA LATER TONIGHT. CURRENT FORECAST APPEARS TO HAVE A GOOD HANDLE ON IT. FORECAST LOWS LOOK REASONABLE AS WELL. SO ONLY MADE SOME MINOR ADJUSTMENTS TO GRIDS TO BLEND IN LATEST OBSERVATIONS. /ISSUED 334 PM EDT TUE MAR 13 2007/ SHORT TERM /TONIGHT THROUGH THURSDAY NIGHT/... SPRING PREVIEW IN PROGRESS AS DEEP LO LVL WAA AND STRONG SW GULF FLO HAS HELPED TO LIFT TEMPS WELL INTO THE 70S ACRS FCST AREA THIS AFTN. CVG/CMH/DAY ALL LOOK LIKE THEY WILL COME VERY CLOSE TO OR REACH THEIR RECORD HIGHS BEFORE THE AFTN IS FINISHED. ALL THREE SITES ARE CURRENTLY WITHIN 3 DEG OF THOSE RECORDS. SCT CU FIELD HAD DVLPD ACRS SRN 1/2 FCST AREA AS WELL. FAIRLY ACTIVE WX PATTERN IN STORE FOR OH VLY OVER NEXT 48 HOURS AS FRNTL BNDRY SAGS SLOWLY SOUTH FROM THE NORTH AND GULF MOISTURE CONTINUES TO SURGE NORTH ON STRONG SRLY FLO SOUTH OF BNDRY. MULTIPLE CHANCES FOR CONVECTION ACRS OH VLY...BEGINNING OVERNIGHT AS QUICK MOVING MID LVL S/WV APPCHS FROM SOUTHWEST. THIS FEATURE HELPING TO KICK OFF SCT -SHRA ACRS MID MISSISSIPPI VLY THIS AFTN. NICE SURGE OF ISENT LIFT DVLPS AHEAD OF THIS FEATURE ON STRENGTH OF A 35KT 850 LLJ LATE TONIGHT. THIS COMBINED WITH AXIS OF ELEVATED INSTABILITY SHOULD ENABLE FAIRLY WIDESPREAD COVERAGE OF -SHRA AND SCT TSTMS FROM AROUND MIDNIGHT ON THRU THE REST OF THE NIGHT. BEST COVERAGE TO PCPN WILL BE SOUTH OF I-70 WHERE 70-80 POPS HAVE BEEN EMPLOYED. AXIS OF LO LVL CONV QUICKLY SHIFTS EAST ACRS FCST AREA BTWN 06Z AND 14Z...WITH MUCH OF THE PCPN EAST OF FCST AREA BY MID MRNG WED. PCPN AMOUNTS OF 0.25-0.50 INCHES SEEM A GOOD BET OVERNIGHT. SHOULD GET A BREAK AFTER PCPN EXITS TO THE EAST IN THE MRNG. SVRL FACTORS THEN COME INTO PLAY WED THAT WILL DETERMINE TSTM COVERAGE AND INTENSITY. FIRST AND FOREMOST...MODELS DISAGREE TO SOME EXTENT ON THE AMOUNT OF CLOUD COVER ACRS REGION INTO AFTN HOURS. NAM IS MORE GENEROUS IN ALLOWING FOR SOME SUN WHILE GFS HOLDS ONTO MORE CLOUDS. BETTER DIURNAL HEATING COMBINED WITH SURGE OF L60S DEWPTS CONTRIBUTING TO SBCAPES APPCH 2000 J/KG OFF OF THE 12Z NAM. BELIEVE THESE AMOUNTS ARE GOING TO BE VERY TOUGH TO REALIZE...PARTLY BECAUSE NOT SOLD ON THE AMOUNT OF SUN DURING THE AFTN AND STILL FEEL FCST DEWPTS ARE A TAD HIGH. SBCAPES APPCHG 1000 J/KG OFF OF 12Z GFS APPEAR MUCH MORE REASONABLE WITH DEWPTS IN THE M/U50S AND APPCH 60 DEG. MORE ORGANIZED TSTMS WILL LIKELY BE CLOSER TO QUASI STATIONARY FRNTL BNDRY PROGGED TO BE ACRS NRN OH WED AFTN. 0-6KM BL SHEAR (20-30 M/S) AND SR HELICITIES (100-200 M2/S2) VALUES ARE HIGHER ACRS NRN FCST AREA DURING THE LATE AFTN/ERLY EVNG...BUT OVERALL FORCING IS MARGINAL AT BEST. SWODY2 PLACES FCST AREA INTO SLGT RISK FOR SVR WX. WHILE A FEW SVR STORMS ARE CERTAINLY NOT OUT OF THE QUESTION (ESPECIALLY CLOSER TO THE BNDRY)...COMBINATION OF WEAK MID/UPR LVL FORCING AND THE QUESTIONS SURROUNDING AMOUNT OF AVAIL INSTABILITY LEAD ME TOWARDS THIS BEING MORE OF AN ISOLD THREAT AT BEST WITH THE CONVECTION REMAINING SCT. GUSTY WINDS AND SOME HAIL WOULD BE THE MAIN CONCERNS WITH ANY STRONG TO SVR STORMS. FROM WED NIGHT ON...FOCUS THEN TURNS TO PROGRESSION OF FRNTL BNDRY THRU FCST AREA WITH MODEL GUID DIFFERING WIDELY AT THIS POINT. 12Z GFS IS THE MOST PROGRESSIVE SOLN...PUSHING FRONT THRU MUCH OF THE FCST AREA BY THURS MRNG. 12Z ECMWF AND MANY OF THE 12Z GFS ENSEMBLE MEMBERS ARE NOT FAR BEHIND...WITH FRONT SOUTH OF THE OHIO RIVER BY THURS AFTN. 12Z NAM AND NGM SOLNS HOLD THE FRONT UP THE LONGEST...ALLOWING SVRL WAVES OF LO PRES TO RIDE THRU REGION BEFORE PUSHING BNDRY SOUTH THURS NIGHT. HAVE CHOSEN A MIDDLE GROUND APPCH WITH REGARDS TO FROPA...SIMILAR TO 12Z ECMWF/12Z GFS ENSEMBLES WHICH HAVE SUPPORT FROM THE SREF AND 00Z GFS. THE TIMING OF THE FROPA HAS MAJOR IMPACTS ON HIGHS THURS AS THERE SHOULD BE A FAIRLY SHARP TEMP CONTRAST EITHER SIDE OF THE FRONT. THE FLOODING POTENTIAL ALSO WOULD APPEAR LOWER WITH THE FASTER FROPA. ENTIRE FCST AREA LKLY TO SEE A GOOD AMOUNT OF RAIN OUT OF THIS SYSTEM AS STRONG LO LVL CONV WILL COMBINE WITH PWATS ABV 1.25 INCHES AND STRONG DIFFLUENT FLO IN UPR LVLS. IF THE FRONT HANGS ACRS THE NORTHERN FCST AREA LONGER WED NIGHT/THURS AS 12Z NAM AND NGM SOLNS ARE INDCG...WOULD BE MORE CONCERNED ABOUT POTENTIAL FOR FLOODING. SOILS ARE WETTEST NORTH OF I-70 WHERE DEEP SNOWPACK HAS FINALLY MELTED. PCPN CHANCES WILL LINGER THURS NIGHT AS SFC WAVE ALONG FRNTL BNDRY MOVES THRU APPALACHIAN MTNS. ENUF COLD AIR BEHIND THE FRONT MAY ALLOW FOR RAIN TO MIX WITH A FEW SNOW FLAKES ACRS CNTRL OH LATE THURS NIGHT. TEMPS...PREFERRED WARMER MET GUID TONIGHT...THEN GENERALLY TOOK A SPLIT OF DIVERGING GUIDANCE BTWN WARMER MET AND COOLER MAV FOR WED AND THURS. DEPENDING ON HOW MUCH SUN CAN BREAK THRU THE CLOUDS ON WED...MUCH OF THE FCST AREA SHOULD AGAIN BE ABLE TO GET TO 70 DEG. POSN OF FRNTL BNDRY WILL MAKE ALL THE DIFFERENCE REGARDING AFTN HIGHS THURS...COULD EASILY SEE A 20 DEG DIFFERENCE IN TEMPS FROM NORTH TO SOUTH ACRS FCST AREA. RYAN /ISSUED 334 PM EDT TUE MAR 13 2007/ LONG TERM /FRIDAY THROUGH TUESDAY/... EXTENDED MODELS REMAIN IN CONSIDERABLE DISAGREEMENT. THERE IS MUCH RUN TO RUN VARIABILITY WITH THE GFS AND CORRESPONDING MEX TEMP GUIDANCE. FOR FRIDAY...PCPN WINDS DOWN NW TO SE EARLY AS HIGH PRESSURE BUILDS BEHIND A COLD FRONT. 12Z MEX TEMP GUIDANCE HAS TRENDED DOWN AFTER 00Z MEX TEMP GUIDANCE TRENDED MUCH WARMER. AT THIS POINT...HIGH TEMPS WILL MOSTLY BE IN THE MID 40S TO LOWER 50S. FRIDAY NIGHT INTO SATURDAY...THE GFS HAS AN UPPER TROF WORKING ACROSS THE AREA. SCATTERED SNOW SHOWERS/WINTRY MIX WILL CHANGE OVER TO RAIN SHOWERS IN THE AFTERNOON. HIGH TEMPS WILL MOSTLY BE IN THE 40S. HIGH PRESSURE BUILDS BRIEFLY SUNDAY BEFORE A COLD FRONT SAGS ACROSS THE REGION MONDAY INTO TUESDAY. AS AFOREMENTIONED...MUCH UNCERTAINTY EXISTS...PARTICULARLY WITH TEMPS. CURRENT GUIDANCE IS NEAR NORMAL FOR THIS TIME PERIOD. OBVIOUSLY...THIS WILL PROFOUNDLY AFFECT P-TYPES. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...NONE. KY...NONE. IN...NONE. &&
