The episode as NWS ILX wrote it up.
A cluster of thunderstorms developed across Iowa, then tracked southeastward along a warm front into central Illinois during the afternoon of May 27th. Some of the storms became severe, producing damaging winds in excess of 70 mph across portions of northern Sangamon into western Macon counties. The most widespread wind damage occurred near the town of Riverton, where numerous mobile homes suffered damage from falling trees.
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 May 27, 11:33 AM CST, 2 hours 4 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LINCOLN IL 1233 PM CDT MON MAY 27 2013 .DISCUSSION... ISSUED 1030 AM CDT MON MAY 27 2013 WELL DEFINED MCV ON RADAR CENTERED JUST EAST OF BLOOMINGTON... WITH LINGERING SHOWERS DIMINISHING AHEAD OF IT. MCS TO OUR WEST CONTINUES TO DROP SOUTHEAST...WITH A COUPLE OF WAKE LOWS NORTH OF IT ACROSS IOWA. THE CORE OF THE LINE OF STORMS IS PROJECTED TO REMAIN IN MISSOURI. HAVE SEEN AN OVERALL EASTWARD PUSH OF THE RAIN WHICH WAS NEAR QUINCY AT 1030 AM...AND THE HRRR MODEL...WHICH HAS HANDLED THIS MCS PRETTY WELL...BRINGS THE REMNANTS THROUGH THE SOUTHWEST HALF OF THE CWA EARLY AFTERNOON AND REACHING THE EASTERN CWA LATE. HAVE SEEN TEMPS ACROSS THE SOUTHEAST SURGING TOWARD 80 DEGREES WITH SOME SUNSHINE FILTERING THROUGH...AND WILL NEED TO MONITOR THE INSTABILITY HERE AS THE STORMS ARRIVE FOR ANY ENHANCEMENT. GEELHART && .AVIATION... ISSUED 1233 PM CDT MON MAY 27 2013 LINE OF THUNDERSTORMS PUSHING EAST FROM THE MISSISSIPPI RIVER AT MIDDAY...SHOULD REACH KSPI TOWARD 1930Z AND KCMI TOWARD 22Z. HAVE MENTIONED SOME TEMPO IFR CONDITIONS AS THE WORST OF THE LINE PASSES. MORE GENERAL IFR CONDITIONS LIKELY FURTHER NORTH TOWARD KPIA/KBMI ON THE NORTH SIDE OF THE CONVECTIVE CLUSTER. AS HAS BEEN THE CASE THE LAST COUPLE DAYS...EVENING CONVECTIVE REDEVELOPMENT IS A SIGNIFICANT CONCERN...AND FAVORED MORE ALONG/NORTH OF KPIA/KBMI WHERE THE WARM FRONT BECOMES BETTER ESTABLISHED. HAVE MENTIONED PREVAILING MVFR CONDITIONS WITH -TSRA IN THOSE AREAS AND ONLY VCTS FURTHER SOUTH WHERE IT IS MORE QUESTIONABLE. TUESDAY MORNING...SHOULD SEE GUSTY WINDS DEVELOP AS HIGHER WINDS ALOFT MIX TOWARD THE SURFACE...WITH SOME POTENTIAL FOR THUNDER AGAIN BY LATE MORNING. GEELHART && .PREV DISCUSSION... ISSUED 340 AM CDT MON MAY 27 2013 SHORT TERM...TODAY THROUGH TUESDAY WARM FRONT AT 08Z EXTENDED FROM THE IA/MO BORDER SOUTHEAST TO NEAR MOUNT VERNON. FRONT HAS BECOME MORE DIFFICULT TO DEFINE DUE TO SEVERAL RECENT CONVECTIVE COMPLEXES AND RESULTING OUTFLOW. THESE COMPLEXES HAVE BEEN FED BY STRONG 850-700 MB WARM/MOIST ADVECTION...AND LATEST VWP/S OVER MO INDICATE 30-40 KT FLOW AT THESE LEVELS SUPPLYING INSTABILITY INTO THE LOW AND MID LEVEL BOUNDARIES. THIS ACTIVITY SHOULD FESTER INTO THE MORNING BEFORE THE LLJ VEERS AND WEAKENS BY 15Z. NEXT LARGER UPSTREAM MCS OVER WESTERN IA IS FORECAST TO DIMINISH BY HI-RES MODELS BY TIME IT REACHES THE MS RIVER LATER THIS MORNING...BUT THIS COULD SEND ANOTHER OUTFLOW BOUNDARY INTO THE CWA THIS AFTERNOON. IF CLEARING OCCURS AFTER THIS MORNINGS STORMS...STRONG TO SEVERE T-STORMS WILL BE POSSIBLE THIS AFTERNOON DUE TO SHEAR NEARBY SYNOPTIC AND MESOSCALE BOUNDARIES AND ENHANCED INSTABILITY. SPC HAS EXPANDED DAY 1 SLIGHT RISK TO INCLUDE THE WESTERN CWA. PRECIPITABLE WATER REMAINS HIGH AT 1.5-1.7 INCHES SO PERIODS OF HEAVY RAIN POSSIBLE ONCE AGAIN...AND WITH SATURATED GROUND FROM RECENT RAINS 1-HR FFG NUMBERS ARE UNDER 1.5 INCHES FOR MUCH OF THE WESTERN HALF OF THE CWA. WILL EXTEND CURRENT FLASH FLOOD WATCH THROUGH 12Z TUE AND EXPAND TO INCLUDE ALL COUNTIES ALONG AND WEST OF A MCLEAN TO SHELBY LINE. THE WARM FRONT WILL GRADUALLY LIFT NORTH OF THE CWA ON TUESDAY BUT THIS PROCESS MAY BE IMPEDED BY CONVECTIVE OUTFLOW. RECENT MODEL RUNS NOW SHOW MORE STORMS WILL BE POSSIBLE TUESDAY...AND HAVE HIGHEST CHANCES IN THE NORTHERN CWA CLOSER TO THE BOUNDARY. FORECAST SOUNDINGS LOOK MORE IMPRESSIVE FOR SEVERE STORMS AS THE BOUNDARY LAYER WILL BE MORE UNSTABLE THAN TODAY AND DEEP LAYER SHEAR INCREASES. LONG TERM...WEDNESDAY THROUGH SUNDAY BY WEDNESDAY WE WILL BE FIRMLY IN THE WARM SECTOR WITH THE FRONT LIFTING WELL NORTH. BRISK SOUTHERLY WINDS WILL PRODUCE WIDESPREAD MID 80S HIGHS. AFTER A BRIEF BREAK FROM THE ACTIVE PATTERN...AN UPPER LOW MOVING INTO THE PLAINS WILL BRING INCREASING STORM CHANCES FROM THE WEST FOR THURSDAY AND FRIDAY. 00Z MODEL RUNS ARE MORE PROGRESSIVE WITH THIS SYSTEM THAN 24 HOURS AGO...AND HIGHER CHANCE POPS FOR THE WESTERN HALF OF THE CWA FROM THE MODEL CONSENSUS FOR THU/FRI LOOK GOOD. THE FAR EAST AND SOUTHEAST CWA MAY STAY DRY UNTIL LATER FRIDAY AND INTO SATURDAY WHEN THE COLD FRONT IS FORECAST TO SHIFT INTO THE STATE. THE SYNOPTIC SETUP FAVORS MORE HEAVY RAIN AND POSSIBLE SEVERE WEATHER WITH THIS SYSTEM. TEMPS SHOULD COOL BACK TO NORMAL IN THE POST-FRONTAL AIRMASS ON SUNDAY. 25 && .ILX WATCHES/WARNINGS/ADVISORIES...
