The episode as NWS ILX wrote it up.
A warm front lifting through central Illinois during the late evening of June 7th produced scattered thunderstorms. One of these thunderstorms produced a lightning bolt which struck a mobile home near Henry and destroyed it.
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 Lincoln, IL wrote its last area forecast discussion before the first event at Jun 7, 7:30 PM CST, 1 hour 15 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LINCOLN IL 830 PM CDT SUN JUN 7 2009 .DISCUSSION... ISSUED 830 PM CDT SUN JUN 7 2009 MAIN SYNOPTIC FEATURES ARE SIMILAR TO LAST EVENING WITH LOW PRESSURE NEAR OMAHA AND A WARM FRONT EXTENDING THROUGH SOUTHERN IOWA INTO NORTHERN ILLINOIS. CONVECTION HAS GOTTEN AN EARLIER START THIS EVENING OUT WEST IN THE FORM OF ISOLATED INTENSE SUPERCELLS. SOME TEMPORARY WEAKENING MAY OCCUR THIS EVENING...BUT WATER VAPOR SATELLITE IMAGERY SHOWS A STRONG SHORTWAVE EMERGING FROM THE ROCKIES INTO THE WESTERN PLAINS WHICH WILL CAUSE ANOTHER INCREASE LATER TONIGHT. WITH THE MEAN UPPER FLOW BACKING AHEAD OF THE SHORTWAVE... THE STORMS HAVE MORE OF A NORTHEASTERLY MOVEMENT THAN EASTERLY. THEREFORE IT WILL PROBABLY BE WELL AFTER MIDNIGHT ONCE AGAIN BEFORE THE ORGANIZED CONVECTION GETS INTO THE AREA. IN THE MEANTIME... ELEVATED CONVECTION NOW FROM SOUTHWEST OF SPRINGFIELD TO DANVILLE WILL CONTINUE TO MOVE EASTWARD WITH THE ASSISTANCE OF A WEAK LEAD SHORTWAVE THAT IS ABOUT HALFWAY THROUGH THE STATE. NO SEVERE EXPECTED FROM THIS ACTIVITY. SINCE THE SURFACE WARM FRONT STILL LIES ACROSS OUR NORTHERN COUNTIES...SOME EVENING DEVELOPMENT STILL NOT OUT OF THE QUESTION SO WILL NOT MAKE ANY POP ADJUSTMENTS FOR TONIGHT. REMAINDER OF THE FORECAST ALSO LOOKS REASONABLE FOR NOW. 04 && .AVIATION... ISSUED 615 PM CDT SUN JUN 7 2009 BAND OF WK CONVECTION UIN-AAA-DNV IS BEING AIDED BY OUTFLOW BNDRY FM PREV TSTMS AS WELL AS MID LVL SHORTWAVE NOW ENTERING WRN IL. PCPN SHOULD DMNSH AS THE WV PASSES E OF THE AREA BY 03Z. UPSTREAM...MORE ROBUST CONVECTION IS INCRSG OVR WRN MO...AND THE REMNANTS OF THIS ACTIVITY MAY MAKE IT INTO THE WRN AREAS 09Z-15Z MON. THERE IS A PSBLTY FOR A RENEGADE STORM TNGT BTWN THESE SYSTEMS...BUT TOO LOW FOR MENTION. MAIN SYNOPTIC COLD FRONT HAS BEEN STALLED OVR IA/KS... BUT WL GET A KICK EWD EARLY MON AS A STG UPR TROF EMERGES FM THE ROCKIES INTO THE PLNS. THIS FNT SHOULD MV INTO CNTL IL AROUND 18Z MON...WITH ANOTHER UPSWING IN TSTM CVG/INTENSITY. 04 && .PREV DISCUSSION... ISSUED 303 PM CDT SUN JUN 7 2009 MODELS IN REASONABLE AGREEMENT THROUGH ONLY 30HRS BUT THEN GFS DEVELOPS A SECONDARY LOW OF THE SFC FRONT COMING THROUGH TOMORROW CAUSING A LITTLE DELAY IN THE FRONT COMING THROUGH. PREFERENCE IS TO AGREE WITH THE NAM-WRF AND SREF...WHICH ALSO AGREES BETTER WITH THE ECMWF AND CANADIAN. PAST 30HRS...A BLEND OF THE MODELS WITHOUT THE GFS LOOKS FINE. MAIN CONCERNS THIS PACKAGE INCLUDE PCPN CHANCES TONIGHT THROUGH TOMORROW NIGHT AS SYSTEM LIFTS OUT OF THE SOUTHWEST TONIGHT AND MOVES THROUGH THE CWA TOMORROW. THE NEXT CONCERN WILL BE ANOTHER LOW THAT DEVELOPS ON THE TAIL OF THE FRONT IN THE SOUTHERN PLAINS AND RIDES INTO THE AREA FOR WED THROUGH THURSDAY. IN THE EXTENDED...A BLEND OF THE MODELS IS FINE AS THE FRONTAL SYSTEM SHOULD MOVE SOUTH OF THE AREA WITH MINIMAL CHANCES OF PCPN FOR THE REST OF THE WEEK AND INTO THE WEEKEND. SHORT TERM...TONIGHT THROUGH WEDNESDAY NIGHT EARLY THIS AFTERNOON...A FRONTAL SYSTEM STRETCHES FROM NORTHERN IL BACK TO SERN NEB AND THEN DOWN INTO KS. STRONG TO SEVERE CONVECTION IS EXPECTED TO DEVELOP ON THE COLD FRONT OVER KS/NEB AND IOWA/MO. WEAKER SHOWERS AND THUNDERSTORMS CONTINUE TO MOVE ACROSS IL FROM MORNING MCS. WILL BE KEEPING LIKELY POPS TO COVER FOR THIS PCPN FOR THIS EVENING ONLY. CONVECTION THAT DEVELOPS ALONG THE WARM FRONT TO THE NORTHWEST COULD SLIDE DOWN INTO THE REGION AFTER MIDNIGHT...SO WILL KEEP HIGH CHC POPS IN THE NORTH FOR THAT. AS THE 500 TROUGH AXIS CONTINUES TO LIFT OUT OF THE WESTERN US...THE SFC LOW WILL TRACK NORTHEAST AND REACH EASTERN IOWA BY 12Z...WITH A COLD FRONT STRETCHING SOUTHWEST. BY 18Z THE LOW WILL BE IN SOUTHERN WI...AND THEN MICH BY 00Z. THE ASSOCIATED COLD FRONT WILL MOVE EAST THROUGH THE PERIOD AND STORMS ARE EXPECT TO DEVELOP ALONG THE FRONT IN THE AFTERNOON AND CONTINUE INTO THE EVENING HOURS. CAPE VALUES OF NEAR 3000 J/KG AND LIS OF -8 WILL BE SUPPORTIVE OF THESE STORMS BEING STRONG TO SEVERE. WIND FIELD IS RATHER WEEK AND UPPER LEVEL SUPPORT ALSO SEEMS MINIMAL. HOWEVER...LAPSE RATES WILL BE STEEP SO LARGE HAIL AND DAMAGING WINDS SEEM TO BE THE PRIMARY CONCERN WITH THE STORMS. STRAIGHT LINE HODOGRAPH DOES SUPPORT SOME SUPERCELLS...BUT IN MULTICELL FASHION. THIS ALSO SUPPORTS SPLITTING CELLS WITH SUFFICIENT SHEAR FORM SOME ISOLATED TORNADOES POSSIBLE. FRONT SHOULD MOVE THROUGH MONDAY EVENING AND SHOULD PUSH FAR ENOUGH SOUTH THAT THE WHOLE CWA SHOULD BE DRY FOR TUE. THEN ANOTHER SYSTEM DEVELOPS ON THE TAIL END OF THE FRONT AND LIFTS AGAIN NORTHEAST TOWARD THE AREA FOR TUE NIGHT. MODELS INDICATE A WARM FRONT WILL LIKELY BE SITTING EITHER OVER THE STATE OR NEAR THE STATE TO THE WEST. THIS WILL THEN BE THE FOCUS FOR MORE THUNDERSTORMS DEVELOPING FOR WED AND WED NIGHT. WILL CONTINUE TO HAVE CHC POPS FOR THE PERIOD BUT NOT INCREASE TO HIGHER POPS SINCE STILL SOME UNCERTAINTY AND MAY DEPEND ON WHAT HAPPENS TOMORROW AND TOMORROW NIGHT. TEMPS WILL BE WARM AGAIN TOMORROW BUT ANY CLOUD COVER FROM TNGT CONVECTION COULD KEEP TEMPS FROM GETTING TO THE NORMAL CATEGORY... LIKE SOME AREA TODAY. STAYED WITH BLEND OF THE GUIDANCE AND WENT WARMER THAN MET FOR TUE HIGHS AND COOLER THAN MAV FOR TUE NIGHT. LONG TERM...THURSDAY THROUGH SUNDAY THE SYSTEM AT THE END OF THE SHORT TERM WILL KEEP A CHANCE OF PCPN IN THE CENTRAL AND SOUTH FOR THURSDAY BEFORE THE FRONT GETS PUSHED FAR ENOUGH SOUTH FOR US TO DRY OUT. DRY WEATHER DOES LOOK REASONABLE FOR FRI AND INTO THE WEEKEND BUT WILL HAVE A SLIGHT CHANCE FOR SAT NIGHT AND SUNDAY AS ANOTHER SYSTEM IS FORECAST TO DEVELOP OUT WEST AND POSSIBLY GIVE US MORE PCPN. HOWEVER...THIS IS FIRST TIME MODELS ARE FORECASTING THIS SO WILL GO LOW FOR NOW. TEMPS WILL REMAIN COOLER AS CWA STAYS ON THE NORTH SIDE OF THE BOUNDARY. AUTEN && .ILX WATCHES/WARNINGS/ADVISORIES... NONE. &&
