The episode as NWS ILX wrote it up.
A strengthening area of low pressure in the northern Plains resulted in a developing warm front near the Tennessee Valley on November 24th. This warm front slowly lifted north toward the Ohio Valley on November 25th, which resulted in several rounds of showers and thunderstorms in east central and southeast Illinois. One of these thunderstorms produced lightning damage in Champaign County, as well as 36 to 48 hour rain totals ranging from 2.50 to 3.50 of rain. There were no reports of significant flooding or flood damage.

PRECIPITATION SHIELD HAS PUSHED OUT OF SE IL EARLY THIS EVENING WITH CLOUDS ON THE DECREASE FROM WEST TO EAST. FLOOD HEADLINES HAVE BEEN DROPPED FOR EAST CENTRAL AND SOUTHEAST ILLINOIS BASED ON RADAR TRENDS THIS EVENING WITH THE MENTION OF PRECIP IN THE ZONES AND GRIDS REMOVED AS WELL. THE REST OF THE FORECAST LOOKS ON TRACK WITH OVERNIGHT LOWS EXPECTED TO DROP INTO THE MID TEENS NORTH TO THE MIDDLE 20S SOUTHEAST. QUIET WEATHER TO DOMINATE THE AREA THRU THE REMAINDER OF THE HOLIDAY WEEKEND. SMITH && .AVIATION... ISSUED 542 PM CST THU NOV 25 2010 FRONTAL BOUNDARY HAS CONTINUED TO SHIFT SLOWLY AWAY FROM CENTRAL ILLINOIS LATE THIS AFTERNOON AND EXPECT THAT TREND TO CONTINUE TONIGHT WITH VFR CONDITIONS PREVAILING ACRS ALL TAF SITES. SFC WINDS WILL BE FROM THE NORTHWEST TO WEST AT AROUND 10 KTS TNT AND WEST AT 15 TO 20 KTS BY LATE FRI MRNG WITH A FEW GUSTS TO 25 KTS DURING THE AFTN. WINDS SHOULD QUICKLY DIMINISH BY EVENING. SMITH && .PREV DISCUSSION... ISSUED 300 PM CST THU NOV 25 2010 SHORT TERM...TONIGHT THROUGH SUNDAY... MOST OF THE SIGNIFICANT WEATHER IN THE SHORT TERM WILL BE IN THE FIRST 6 HOURS. DEEP PLUME OF RICH MOISTURE CONTINUES TO FLOW THROUGH SERN IL LATE THIS AFTERNOON...AND SOME OF THE RIVERS/STREAMS HAVE BEGUN TO RISE. SO FAR...THE ONLY OFFICIAL RIVER FORECAST POINT THAT IS EXPECTED TO FLOOD IS CLAY CITY...BUT OTHER MINOR STREAMS AND LOW SPOTS ARE HOLDING QUITE A BIT OF WATER TOO. SINCE FLOOD WARNINGS ARE IN EFFECT UNTIL 630 PM...WILL EXTEND THE WATCH UNTIL 900 PM. FURTHER NW...MOST OF THE PRECIPITATION HAS BEEN IN THE FORM OF RAIN WITH SOME LIGHT SNOW/SLEET/FREEZING RAIN FOR A SHORT PERIOD BEFORE ENDING. NO ROAD PROBLEMS HAVE BEEN REPORTED SINCE THE PRECIPITATION IS LIGHT AND EVAPORATION IS BEING AIDED BY GUSTY NORTHWEST WINDS IN THE 15-25 MPH RANGE. THE OVERALL PRECIPITATION SHIELD IS NOW ALONG/SE OF I-55 AND IS MAKING PROGRESS OUT OF THE AREA. A SIMILAR PRECIPITATION-TYPE TRANSITION IS EXPECTED IN ERN/SERN IL EARLY THIS EVENING...THEREFORE NO WINTER HEADLINES ARE REQUIRED AT THIS TIME. ALL OF THE PRECIPITATION SHOULD BE DONE BEFORE 06Z. THE REMAINDER OF THE SHORT RANGE FORECAST WILL BE DRY WITH A SLOW WARMING TREND THROUGH SUN. A MINOR SHORTWAVE WILL ROTATE SEWD THROUGH THE MIDWEST ON FRI...BUT MOISTURE WILL BE TOO SPARCE FOR ANYTHING MORE THAN A FEW CLOUDS. FRI WILL BE RATHER COOL WITH LOW LEVEL COLD ADVECTION...WITH HIGHS REMAINING IN THE 30S MOST AREAS. A SURFACE RIDGE WILL MOVE THROUGH THE AREA LATE SAT AND EARLY SUN... WITH TEMPERATURES NOT AS COOL. LONG TERM...MONDAY THROUGH THURSDAY... LONGER RANGE MODELS ARE IN REASONABLE AGREEMENT THIS AFTERNOON. NEXT LONG WAVE UPPER TROUGH WILL COME INTO THE PLAINS LATE SUN...AND THIS WILL FACILITATE A FAIRLY RAPID RETURN OF DEEP MOISTURE FROM THE GULF OF MEXICO. ASSOCIATED SURFACE LOW WILL MOVE FROM WRN KS SUN NGT TO LAKE SUPERIOR BY MON AFTN. BY THAT TIME THE TRAILING COLD FRONT WILL STRETCH SWD FROM THE LOW THROUGH AT LEAST WRN IL INTO THE ARKLATEX. LIKE THE PREVIOUS SYSTEM...UNSEASONABLY RICH LOW LEVEL MOISTURE WILL SURGE NWD THROUGH IL ALONG WITH A STRONG SWLY UPPER JET. WILL THEREFORE HAVE LIKELY POPS FOR SHOWERS...AND CHANCE POPS FOR THUNDER...ON MON AND LINGER THEM IN THE EAST MON EVENING. MOST OF THE MODEL OUTPUT HAS THE PRECIPITATION E OF THE AREA ON TUE...BUT WILL RETAIN SLGT CHC POPS DUE TO TIMING DIFFERENCES. IF THE LIGHT RAIN HANGS ON LONG ENOUGH...THERE WILL BE A CHANCE OF RAIN AND/OR LIGHT SNOW IN THE NORTH AS COLD AIR COMES IN AFTER FRONTAL PASSAGE. HIGH PRESSURE WILL THEN DRY THINGS OUT FOR WED AND THU. A DECENT CHUNK OF COLD AIR WILL MOVE ACROSS THE MIDWEST FROM CANADA ON WED...KEEPING HIGHS IN THE 30S. THE COLD AIR WILL BE SHORT-LIVED AS THE UPPER PATTERN IS EXPECTED TO REMAIN PROGRESSIVE...THUS BRINGING WARM ADVECTION AGAIN BY NEXT THU. && .ILX WATCHES/WARNINGS/ADVISORIES... NONE. &&
