What happened
The episode as NWS IND wrote it up.
A surface low pressure center over central Illinois assisted in developing isolated storms that pushed east into western Indiana on the afternoon of May 21st. Not many severe reports were received from across the warning area. However, isolated observations of flash flooding, pea to golf ball sized hail, strong winds, and even a funnel cloud were reported with this line of isolated storms. The majority of the reports were received from west-central portions of the state.

Area forecast discussion, May 21, 1:10 PM EST, 7 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE INDIANAPOLIS IN 210 PM EDT FRI MAY 21 2010 .UPDATE... UPDATED SYNOPSIS...NEAR/SHORT/LONG TERMS & HYDROLOGY. && .SYNOPSIS... A LOW PRESSURE SYSTEM WILL PUSH EASTWARD ACROSS ILLINOIS...INDIANA...AND OHIO THIS AFTERNOON AND EVENING...DRAGGING A COLD FRONT THROUGH THE AREA. THIS SYSTEM WILL MOVE EAST OF THE REGION AFTER MIDNIGHT. HIGH PRESSURE WILL BUILD BACK OVER THE REGION FOR THIS WEEKEND...BRINGING MUCH DRIER AND WARMER WEATHER. && .NEAR TERM /TONIGHT/... ANALYSIS AS OF 2 PM THIS AFTERNOON DEPICTS A WELL DEFINED UPPER LOW SITUATED ACROSS CENTRAL ILLINOIS AND INDIANA. THIS SLOW WILL SLOWLY CONTINUE TO SHIFT EASTWARD THROUGH THIS EVENING. ALSO...A WEAK SURFACE LOW IS LOCATED OVER CENTRAL ILLINOIS WITH AN ASSOCIATED COLD FRONT TRAILING TO THE SOUTH. FORECAST FOCUS FOR THE NEAR TERM IS PRECIP AND CONVECTIVE CHANCES. LATEST VISIBLE SATELLITE IMAGERY SHOWS CLOUDS BECOMING MORE SCATTERED ALONG MUCH OF CENTRAL ILLINOIS. AS THIS SYSTEM SHIFTS EASTWARD, EXPECT CLOUDS OVER CENTRAL INDIANA TO BEGIN SCATTERING OUT (SOMEWHAT) AS WELL...POSSIBLY ALLOWING UP A FEW MORE PEAKS OF SUNSHINE, WHICH WILL AID INSTABILITY. THUS FAR THE CURRENT DENSE CLOUD COVER HAS INHIBITED CONVECTION...KEEPING THOSE STORMS THAT HAVE POPPED UP VERY SHALLOW. THIS SHOULD QUICKLY CHANGE AS THE SYSTEM PUSHES EASTWARD ACROSS THE STATE AND CLOUDS BEGIN TO SCATTERED OUT. IF WE DO GET SOME CLEARING...STRONGER TO SEVERE THUNDERSTORMS ARE POSSIBLE, AND WE ARE CURRENTLY STILL IN A SLIGHT RISK FOR SEVERE...IN ADDITION TO THUNDERSTORM WATCH #199 WHICH IS IN EFFECT FOR MUCH OF CENTRAL INDIAN UNTIL 9 PM THIS EVENING. AT THIS POINT MAIN THREATS WILL BE HAIL...WITH A FAIRLY LOW FREEZING LEVEL OF AROUND 11KT FT, GETTING TOPS TO NEAR 30KT FT MAY NOT BE THAT DIFFICULT. A SECONDARY THREAT IS BRIEF VERY HEAVY RAINFALL. WITH PRECIPITABLE WATERS RUNNING NEAR 1.5" ANY STORM THAT DOES FORM COULD HAVE THE POTENTIAL TO DUMP A LARGE AMOUNT OF RAIN OVER ANY GIVEN AREA. FLASH FLOODING IS A POSSIBLE. A THIRD CONCERN IS GUSTY WINDS. SOUNDINGS ARE NOT PARTICULARLY IMPRESSIVE WITH REGARD TO SHEAR...SO THIS IS NOT AT THE TOP OF THE LIST IN TERMS OF THREATS. MARGINALLY SEVERE HAIL AND HEAVY RAINFALL ARE OF PRIMARY CONCERN. FRONT SHOULD BEGIN TO EXIT EAST INTO OHIO BEFORE MIDNIGHT AND SHOWER ACTIVITY WILL BEGIN TO WANE AND ALSO EXIT. LOW TONIGHT MID-UPPER 50S. && .SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/... THIS WEEKEND IS SHAPING UP TO BE VERY PLEASANT...ESPECIALLY WHEN COMPARED TO THE LAST 2 DAYS. SATURDAY WILL HAVE DECREASING CLOUDS AS UPPER RIDGE BUILDS EAST INTO OUR REGION AND SURFACE LOW CONTINUES EAST ACROSS NORTHERN OHIO. BOTH NAM/GFS HAVE TRENDED A LITTLE QUICKER IN ENDING PRECIPITATION BY SATURDAY AND WILL ONLY MENTION LOW CHANCES OF SHOWERS MAINLY RANDOLPH COUNTY FOR SATURDAY MORNING. AS FAR AS TEMPERATURES ARE CONCERNED WILL MAV/MET NUMBERS ARE CLOSE AND SEEM REASONABLE. && .LONG TERM /MONDAY THROUGH FRIDAY/... ECMWF/GEM/GFS CONTINUE TO BE IN GOOD AGREEMENT FOR NEXT WEEK AS A STRONG RIDGE OF HIGH PRESSURE SITUATES ITSELF OVER THE GREAT LAKES REGION. A FEW AFTERNOON SHOWERS CANNOT BE RULED OUT WITH DAYTIME HEATING. HOWEVER...NOT ENOUGH CERTAINTY TO INCREASE POPS AT THIS TIME DUE TO DRY FORECAST SOUNDINGS AND NO LIFTING MECHANISMS. THE BEST CHANCE FOR ANY PRECIPITATION WILL BE LATE IN THE WEEK AS A LOW PRESSURE SYSTEM MOVES ACROSS CANADA. AT THIS TIME...IT LOOKS LIKE IT WILL REMAIN TOO FAR NORTH TO HAVE MUCH OF AN IMPACT. AS FAR AS TEMPS...WENT WITH A BLEND OF MODELS...WHICH ALL SEEM TO HAVE A GOOD HANDLE ON THE WARMER TEMPS. HIGHS WILL GENERALLY TOP OFF IN THE MID TO UPPER 80S WITH AMPLE SUNSHINE...AND LOWS WILL BOTTOM OUT IN THE LOW TO MID 60S. && .AVIATION /DISCUSSION FOR 211800Z TAF ISSUANCE/... LATEST RADAR SHOWS A BAND OF SHOWERS AND THUNDERSTORMS JUST SOUTH OF KLAF AND BETWEEN KHUF/KIND WITH TOPS OF 35-40 FEET. THE ACTIVITY IS MOVING NE AT 25MPH WITH MORE SCATTERED ACTIVITY OVER IN ERN IL. THE ACTIVITY IS OCCURRING AHEAD OF AN UPPER LEVEL LOW NEAR ST. LOUIS..SO IT LOOKS LIKE SCATTERED THUNDERSTORMS WILL BE THE RULE FOR OCCASIONAL MVFR IN THE VICINITY OF THE THUNDERSTORMS. THERE IS A COLD FRONT ASSOCIATED WITH THIS SYSTEM THAT WILL ROTATE SW TO NE ACROSS CENTRAL INDIANA LATE TONIGHT AND EARLY SATURDAY MORNING. AS THE UPPER TROUGH MOVES ACROSS THE AREA AFTER 23/0600Z...MUCH OF THE PRECIPITATION WILL MOVE OUT OF THE AREA...BUT WITH THE COOLER TEMPERATURES AND WET GROUND...LOW CLOUDS/FOG WILL LIMIT VISIBILITIES TOWARDS MORNING WITH THE POSSIBILITY OF SOME IFR CONDITIONS. SKIES ARE EXPECTED TO IMPROVE LATE SATURDAY MORNING GIVING A RETURN TO VFR FLYING CONDITIONS. && .HYDROLOGY... SHOWER AND THUNDERSTORM ACTIVITY THIS AFTERNOON IS EXPECTED TO CREATE LOWLAND FLOODING ALONG PORTIONS OF THE WABASH AND WHITE RIVERS. MUCH OF CENTRAL AND WESTERN INDIANA RECEIVED BETWEEN ONE HALF AND NEARLY 1 1/2 INCHES OF RAIN THURSDAY NIGHT. MOST PRECIPITATION IS EXPECTED TO FALL BY 8 PM THIS EVENING OVER THE AREA OF CONCERN WITH ESTIMATED RAINFALL ON THE ORDER OF ONE QUARTER TO 3 TENTHS OF AN INCH. ONLY A FEW HUNDREDTHS OF AN INCH AT MOST ARE EXPECTED BEYOND THIS BUT GIVEN THE CONVECTIVE NATURE AMOUNTS OF COURSE COULD VARY. WARMING TEMPERATURES AND DRY WEATHER WILL MOVE IN STARTING TOMORROW AND CONTINUE THROUGH EARLY JUNE. THIS WILL ALLOW SOILS TO DRY AND VEGETATION TO GROW RAPIDLY. AS A RESULT...RIVERS IN WESTERN AND SOUTHERN INDIANA WILL RETURN TO NORMAL LEVELS BY MAY 28. && .IND WATCHES/WARNINGS/ADVISORIES...NONE. && SYNOPSIS...SMF NEAR TERM...SMF SHORT TERM...JH/SMF LONG TERM....TDUD AVIATION...DWM HYDROLOGY...BH
