The episode as NWS IND wrote it up.
A line of thunderstorms pushed into western portions of central Indiana during the late evening hours of the 15th of April. This line of storms produced a singular thunderstorm wind damage report in Danville.
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 Indianapolis, IN wrote its last area forecast discussion before the first event at Apr 15, 9:32 PM EST, 1 hour 6 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE INDIANAPOLIS IN 1032 PM EDT FRI APR 15 2011 .UPDATE... THE NEAR TERM SECTION HAS BEEN UPDATED BELOW. && .SYNOPSIS... A FRONT WILL MOVE ACROSS THE AREA TONIGHT WHILE AN UPPER TROUGH MOVES ACROSS ON SATURDAY. ANOTHER FRONT WILL MOVE INTO THE AREA SUNDAY NIGHT AND THEN MEANDER ACROSS THE AREA THROUGH THE MIDDLE OF NEXT WEEK. THIS ACTIVE PATTERN WILL KEEP CHANCES FOR RAIN IN THE FORECAST FOR MUCH OF THE NEXT WEEK. && .00Z MESOSCALE UPDATE... SEVERE CONVECTIVE LINE CONTINUES TO PROGRESS NORTH/NORTHEAST ACROSS ILLINOIS THIS EVENING AHEAD OF STRONG FRONTAL BOUNDARY. MESOANALYSIS INDICATING CONVECTION HAS THRIVED WITHIN A THIN AXIS OF WEAK INSTABILITY PRESENT ACROSS CENTRAL/EASTERN ILLINOIS COMBINED WITH STRONG BL SHEAR AND STORM RELATIVE HELICITIES. MORE UNSTABLE AIRMASS HAS HAD MORE TROUBLE EXPANDING EASTWARD INTO THE FORECAST AREA AND WHILE HIGHER BL SHEAR VALUES ARE PRESENT OVER CENTRAL INDIANA...ATMOSPHERE IS LESS FAVORABLE FOR MAINTENANCE OF ONGOING WIDESPREAD SEVERE WEATHER ASSOCIATED WITH THE LINE AS IT PROGRESSES INTO WESTERN INDIANA OVER THE NEXT HOUR OR TWO. CONVECTION WILL ROTATE INTO AREAS FROM TERRE HAUTE SOUTH THROUGH VINCENNES AROUND OR SHORTLY AFTER 01Z. WHILE THE LINE IS MOVING INTO A LESS FAVORABLE ENVIRONMENT...HIGHEST POTENTIAL FOR STORMS TO REMAIN INTENSE EXISTS IN THESE AREAS ACROSS THE LOWER WABASH VALLEY. GREATEST CONCERNS WOULD BE FOR LARGE HAIL WITH WET BULB ZERO VALUES AROUND 7500FT...AND DAMAGING WINDS AS STRONGER UPDRAFTS TAP INTO THE LOW LEVEL JET OVERHEAD AND BRING THESE WINDS TO THE SURFACE. SEVERE THREAT SHOULD BECOME INCREASINGLY MORE ISOLATED BEFORE DIMINISHING ALL TOGETHER BY 02-03Z AS THE LINE PROGRESSES FURTHER EAST INTO CENTRAL INDIANA INTO AN INCREASINGLY STABLE AIRMASS. WHILE CONVECTION SHOULD BECOME SUBSEVERE BY 03Z ACROSS THE ENTIRE FORECAST AREA...THUNDERSTORMS WILL PERSIST ALONG AND AHEAD OF THE BOUNDARY INTO THE OVERNIGHT AS IT CROSSES THE FORECAST AREA WITH LOCALLY HEAVY RAINFALL...WIND GUSTS TO 45MPH AND SMALL HAIL REMAINING A POSSIBILITY. AFTERNOON NEAR TERM DISCUSSION FOLLOWS BELOW. && .NEAR TERM /TONIGHT/... WIND GUSTS OUTSIDE OF THUNDERSTORMS NO LONGER EXPECTED TO BE 40 MPH BASED ON OBSERVATIONS AND SUNSET. STILL COULD SO SEE SOME GUSTS TO 30 MPH THE REST OF THE EVENING...HOWEVER. LINE OF THUNDERSTORMS WAS NEAR A NEWPORT TO WASHINGTON LINE AT 1030 PM EDT WITHIN NARROW RIBBON OF WEAK INSTABILITY. RAPID REFRESH WAS HANDLING THE TIMING OF THIS LINE VERY WELL AND SHOULD BE EAST OF THE FORECAST AREA BY 06Z. COULD SEE AN ISOLATED SEVERE STORM EARLY SOUTHWEST...HOWEVER NOT EXPECTING MUCH WITH LIMITED AND WEAKENING INSTABILITY. THE FRONT SHOULD PASS SHORTLY THEREAFTER. KEEP LIKELY POPS IN OVERNIGHT AS UPPER LOW ACROSS CENTRAL MISSOURI APPROACHES. UPDATED TEMPERATURES BASED ON CURRENT OBSERVATIONS AND TRENDS. HAD TO DROP THE NORTH SEVERAL DEGREES WITH GRISSOM COMING IN AT 47 DEGREES LAST HOUR. && .SHORT TERM /SATURDAY THROUGH MONDAY/... FOCUS IS ON CHANCES FOR RAIN THROUGH THE PERIOD. NAM LOOKS TOO STRONG WITH THE OVERALL FORCING BY MONDAY GIVEN THE STRENGTH OF THE MAIN FEATURES. WILL GO CLOSER TO A CONSENSUS OF THE OTHER MODELS. UPPER TROUGH WILL MOVE ACROSS THE AREA ON SATURDAY. WITH COLD ADVECTION...LINGERING MOISTURE...AND FORCING FROM THE UPPER TROUGH...LIGHT RAIN SHOWERS LOOK TO BE A GOOD BET. WILL GO LIKELY POPS MOST AREAS. WITH THE COLD ADVECTION...TEMPERATURES WILL HAVE A HARD TIME GOING UP...SO WILL ONLY ALLOW FOR A SMALL RISE. RAIN WILL BE OUT OF MOST OF THE AREA BY EARLY SATURDAY EVENING AS UPPER TROUGH EXITS. WILL ONLY KEEP SLIGHT CHANCE POPS ACROSS THE FAR EAST DURING THE EVENING. MODELS ARE TRYING TO BRING RAIN BACK AS EARLY AS SUNDAY AS CONVERGENCE DEVELOPS ALONG A BOUNDARY ACROSS THE AREA. AT THE MOMENT IT APPEARS THAT BEST FORCING WILL NOT ARRIVE UNTIL LATE SUNDAY...SO WILL KEEP SUNDAY DRY FOR NOW. FRONTOGENETICAL FORCING DEVELOPS SUNDAY NIGHT ALONG AND NORTH OF THE BOUNDARY...SO WILL GO WITH LOW POPS ACROSS THE NORTHERN TWO- THIRDS OF THE AREA. FORCING WEAKENS ON MONDAY SO WENT WITH PERSISTENCE AND KEPT MONDAY DRY. HOWEVER CONFIDENCE IS LOW AND MAY HAVE TO ADD POPS IN SOON. GENERALLY STUCK WITH A BLEND OF MOS FOR TEMPERATURES THROUGH THE PERIOD. && .LONG TERM /MONDAY NIGHT THROUGH FRIDAY/... FOCUS IS ON CHANCES FOR RAIN THROUGH THE PERIOD. STILL SOME DISAGREEMENT WITH THE MODELS ON PLACEMENT OF FRONT THROUGH THE PERIOD...WHICH IS EXPECTED THAT FAR OUT. THIS LEADS TO A LOWER CONFIDENCE FORECAST LATER IN THE PERIOD WITH POTENTIALLY A FRONT NEARBY. WITH NO CLEAR FAVORITE MODEL...STUCK CLOSE TO PERSISTENCE FOR THE MOST PART. AS THE FRONT MEANDERS BACK AND FORTH ACROSS THE AREA THROUGH WEDNESDAY...CHANCES FOR SHOWERS AND STORMS WILL CONTINUE. AT THE MOMENT IT APPEARS THAT THE FRONT SHOULD SINK FAR ENOUGH SOUTH OF THE AREA FOR A DRY FORECAST THURSDAY AND FRIDAY...BUT AGAIN CONFIDENCE IS LOW IN THIS SOLUTION. WENT NEAR HPC FOR MOST TEMPERATURES. && .AVIATION.../DISCUSSION FOR 160000Z TAFS/... POOR FLYING CONDITIONS ANTICIPATED ACROSS CENTRAL INDIANA THROUGH THE FORECAST PERIOD AS A STRONG COLD FRONT MOVES THROUGH THE REGION TONIGHT...FOLLOWED BY A TRAILING UPPER LOW ON SATURDAY THAT WILL KEEP AN ABUNDANCE OF CLOUDS AND RAIN SHOWERS OVER THE OHIO VALLEY. MONITORING AN INTENSE CONVECTIVE LINE AHEAD OF THE FRONT OVER WESTERN ILLINOIS/KENTUCKY THIS EVENING. SOME BREAKS IN THE CLOUDS IMMEDIATELY AHEAD OF THE LINE SHOULD ENABLE AN HOUR OR TWO OF VFR CONDITIONS AT THE TERMINALS THROUGH 02Z. HAVE USED HRRR FOR TIMING OF THE CONVECTION WHICH SHOULD ARRIVE FIRST AT KHUF AROUND OR SHORTLY AFTER 01Z...REACHING KBMG...KIND AND KLAF BETWEEN 01Z AND 03Z. STILL SOME QUESTION AS TO HOW INTENSE THE CONVECTION WILL BE ONCE IT REACHES THE TERMINALS...AS LESS FAVORABLE ATMOSPHERE PRESENT OVER CENTRAL INDIANA FOR SEVERE CONVECTION. AT THE VERY LEAST...WEAK INSTABILITY SHOULD ENABLE THUNDERSTORMS TO IMPACT THE TERMINALS BETWEEN 02 AND 07Z WITH THE POSSIBILITY OF STRONG WIND GUSTS AND PERIODS OF IFR CONDITIONS. EXPECT SOUTHEAST WINDS AHEAD OF THE LINE VEERING TO SOUTHERLY ONCE IT PASSES. WILL UPDATE TAFS AS NECESSARY AS LINE APPROACHES AND CROSSES CENTRAL INDIANA THIS EVENING. TRAILING UPPER LOW WILL MOVE INTO THE REGION NEAR DAYBREAK SATURDAY AND MOVE SLOWLY ACROSS THE REGION THROUGHOUT THE DAY. THIS WILL KEEP CEILINGS HOVERING BETWEEN 1000-1500FT FOR MUCH OF THE DAY WITH OCCASIONAL SHOWERS. WINDS WILL CONTINUE TO GUST TO 25-30KTS ALL DAY AS THE UPPER LOW PASSES. SOUTHWEST WINDS IN THE MORNING WILL VEER TO W/NW BY SATURDAY EVENING. SHOWERS WILL DIMINISH AS THE UPPER LOW PULLS AWAY DURING THE EARLY EVENING. && .IND WATCHES/WARNINGS/ADVISORIES... NONE. && SYNOPSIS...50 MESOSCALE UPDATE...RYAN NEAR TERM...MK SHORT TERM...50 LONG TERM....50 AVIATION...RYAN
