The episode as NWS ILX wrote it up.
An area of low pressure tracked through the region on February 11th, bringing widespread rain and thunderstorms. The heaviest rain fell along and south of a Danville to Shelbyville line, where many locations picked up between 2 and 4 inches. As a result of the rainfall, localized flooding of low-lying rural roads and poor drainage areas occurred. The Little Wabash River rose out of its banks, flooding a few nearby roads. In addition, a few strong thunderstorms developed and produced gusty winds and small hail.

AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LINCOLN IL 1144 AM CST WED FEB 11 2009 .DISCUSSION... ISSUED 1041 AM CST WED FEB 11 2009 LATEST SURFACE ANALYSIS SHOWS LOW PRESSURE NORTHEAST OF SAINT LOUIS...WITH WARM FRONT STRETCHING E/NE JUST EAST OF THE I-55 CORRIDOR. MUCH OF CENTRAL ILLINOIS IS CURRENTLY IN A TEMPORARY PRECIP LULL...AS THE MAIN BAND OF RAIN AND THUNDERSTORMS HAS SHIFTED INTO THE WABASH RIVER VALLEY. MEANWHILE...LARGE AREA OF RAIN WITH A FEW EMBEDDED THUNDERSTORMS CONTINUES TO ROTATE E/NE ACROSS MISSOURI IN ASSOCIATION WITH THE MAIN UPPER LOW. HAVE UPDATED THE GRIDS TO DOWNPLAY THUNDER CHANCES ACROSS THE WESTERN HALF OF THE KILX CWA...WITH ONLY ISOLATED THUNDER MENTION. FURTHER EAST AND SOUTH...COULD STILL SEE SCATTERED THUNDERSTORM DEVELOPMENT FOR THE NEXT FEW HOURS UNTIL THE COLD FRONT FINALLY SWINGS EAST OF THE REGION BY MID-AFTERNOON. MAIN STORY LATER TODAY WILL BE THE WINDS...AS WEST TO NORTHWEST WINDS OF BETWEEN 25 AND 35 MPH DEVELOP ON THE BACK SIDE OF THE DEPARTING LOW. MAY SEE GUSTS AS HIGH AS 45 MPH AT TIMES FROM LATE AFTERNOON INTO THE EARLY EVENING HOURS. && .AVIATION... ISSUED 1144 AM CST WED FEB 11 2009 WARM FRONT CONTINUES TO EXTEND ACROSS CENTRAL ILLINOIS...WITH KDEC AND KCMI IN THE WARM SECTOR AND THE REMAINING TERMINALS ON THE COLD SIDE OF THE STORM SYSTEM. BOTTOM LINE HAS MEANT LOWEST CEILINGS OF UNDER 1000FT ACROSS THE WESTERN TAF SITES AND HIGHER CEILINGS OF BETWEEN 3500 AND 5000FT IN THE WARM AIRMASS AT BOTH KDEC AND KCMI. THIS TREND WILL CONTINUE FOR THE NEXT COUPLE OF HOURS BEFORE LOW PRESSURE TRACKS INTO NORTHERN INDIANA AND THE COLDER AIRMASS AND CORRESPONDING LOWER CEILINGS ARE PULLED FURTHER EAST THIS AFTERNOON AFTER 21Z. AN AREA OF RAIN CURRENTLY ACROSS MISSOURI WILL LIFT INTO CENTRAL ILLINOIS AS WELL...WITH RAIN EXPECTED AT ALL TERMINALS. WILL INCLUDE VCTS AT KSPI...KDEC...AND KCMI...AS CONVECTION DEVELOPING ALONG AND JUST SOUTH OF THE LOW TRACK SKIRTS BY JUST TO THE S/SE OVER THE NEXT 2 TO 3 HOURS. WINDS ARE CURRENTLY FROM THE NORTH ALONG AND WEST OF I-55 AND FROM THE SOUTH EAST OF I-55. WINDS WILL SWITCH TO NW AND INCREASE MARKEDLY AFTER 20Z...WITH GUSTS AS HIGH AS 30 TO 35KT AT TIMES. WINDS WILL GRADUALLY SUBSIDE LATER THIS EVENING AS THE LOW MOVES FURTHER AWAY. SKIES WILL ALSO BEGIN TO CLEAR FROM WEST TO EAST...WITH 12Z NAM-WRF RH PROFILES SUGGESTING ALL TAF SITES CLEARED OUT BY 09Z. BARNES && .PREV DISCUSSION... ISSUED 308 AM CST WED FEB 11 2009 RAPIDLY DEVELOPING SFC LOW PUSHING PLENTY OF WARM MOIST AIR AND PRECIP INTO CENTRAL ILLINOIS THIS MORNING. MAIN UPPER LOW STILL WELL BACK TO THE SW ON SATELLITE IMAGERY...SWIRLING OVER THE CENTRAL PLAINS. SMALL SECONDARY LOW DEVELOPING IN SERN MO WITH H5 PROFILERS SHOWING A DIRECTIONAL DIVERGENCE AT THAT LEVEL AS WELL ENHANCING THE THUNDERSTORM DEVELOPMENT IN SERN MO. FIRST ISSUE FOR THE FORECAST IS THE GENESIS OF THE CURRENT STORM TRACKING THROUGH CENTRAL ILLINOIS TODAY AND THE WIND AND FLOODING ASSOCIATED...AS WELL AS AN ENHANCED THREAT FOR SEVERE WEATHER...ESPECIALLY EAST OF OF INTERSTATE 55. THE NEXT ISSUE WILL BE THE QUICK MOVING WAVE PUSHING THROUGH THE FA ON FRI NIGHT...PROGGED TO BRING ACCUMULATING SNOW...ESP ALONG AND NORTH OF INTERSTATE 74. MODEL PERFORMANCE CONTINUES TO HAVE CONSISTENCY ISSUES AND TONIGHTS PICK HAS ORBITED BACK TO A GFS/ECMWF BLEND... WITH THE NAM A BIT ON THE OUTSIDE AGGRESSIVELY AND TOO FAR TO THE NORTH. SHORT TERM...TODAY AND TONIGHT... MANY ISSUES FOR TODAYS FORECAST...ALL WRAPPED UP WITH WIND AND WATER. A LOT OF PRECIP TO FALL OVER THE FORECAST AREA...AHEAD OF THE SYSTEM AS CENTRAL ILLINOIS COMPLETELY IN A WARM SECTOR THIS MORNING. SFC LOW TRACKING NEWD WILL KEEP THE FA IN SAID WARM SECTOR WITH PLENTY OF STRONG SOUTHERLY FLOW KEEPING THE MOISTURE IN PLACE. ONLY BREAK FROM THAT MIGHT COME IF ENOUGH CONVECTION RACES OUT AHEAD OF THE SYSTEM TO CUT OFF THE INCREASE IN TEMP AND MOISTURE... BUT WILL NOT BE ENOUGH TO KEEP THE RAIN FROM ENDING ALTOGETHER AS THE LIFT INCREASES BASED ON THE RAPIDLY DEEPENING LOW PRESSURE SYSTEM AS THE UPPER TROF BECOMES MORE NEGATIVELY TILTED. PRESSURE GRADIENT INCREASING QUICKLY ENOUGH THAT THE MORNING WINDS WILL EDGE INTO ADVISORY CRITERIA FOR MUCH OF THE FA... OUT OF THE SOUTH EAST OF INTERSTATE 55...AND NORTH AND NORTHWESTERLY ALONG AND WEST OF I55...BECOMING MORE WESTERLY ACROSS THE FA AS THE LOW PULLS THROUGH AND OUT TO THE NE LATE IN THE AFTERNOON. MOST RAPID DEEPENING LIKELY AFTER 18Z AS THE WIND FIELD BECOMES ITS STRONGEST AND MOST UNIFORM. AT THIS POINT...THERE IS AN ADDED THREAT AS THE COLD FRONT TRAILING THE SYSTEM PUSHES THROUGH THE FA. WHEREAS THE PRESSURE GRADIENT WINDS ARE MORE THAN ENOUGH TO PUSH CONDITIONS INTO ADVISORY CRITERIA...ANY ADDED TURBULENCE FROM THE FRONT AND/OR CONVECTION OF ANY SORT WILL BE ENOUGH TO TRANSFER SOME 50-55KT WINDS DOWN FROM JUST OFF THE SFC AT 2 TO 3 KFT. WILL NOT TAKE MUCH OF A RAIN OR THUNDERSTORM TO PUSH SEVERE CRITERIA THROUGH THE FA ON A LARGE SCALE. TRAVELING IN ANY KIND OF HIGH PROFILE VEHICLE SHOULD BE DISCOURAGED THIS AFTERNOON ON NORTH/SOUTH OR NORTHEAST/SOUTHWEST ORIENTED ROADS LIKE I-55. SOME CONCERN SHOULD BE EXPRESSED FOR SOME FLURRY ACTIVITY LATE IN THE WAKE OF THE LOW THIS AFTERNOON. BUT THE LOW PRESSURE SYSTEM SHOULD BE MOVING SO RAPIDLY THAT THIS SHOULD NOT BE MORE THAN A DUSTING. FORECAST MODELS ARE ALSO KEEPING RELATIVELY WARM WITH THIS SPRING LIKE SYSTEM...AND CHANCES FOR THE SNOW HAVE BEEN DROPPING WITH THE TREND OF THE MODELS. HAVE KEPT MENTION OUT OF THE FORECAST AT THIS POINT AS IT WILL BE BRIEF AND MORE LIKELY TO BE HANDLED BY SHORT TERM FORECASTS/NOWS. WINDS WILL KEEP UP QUITE A BIT LONGER THAN THE RAIN...WELL INTO THE EVENING IN THE EAST...FINALLY DYING DOWN BETWEEN 03 AND 06Z. OVERNIGHT SHOULD BE DRY AND A BIT BREEZY...BUT BELOW ANY KIND OF CRITERIA. LONG TERM...TOMORROW THROUGH SUNDAY... MUCH QUIETER IN THE MED/LONG RANGE UNTIL LATE FRIDAY NIGHT AS ANOTHER WAVE PUSHES OUT OF THE WSW. TIMING ISSUES LIKELY FOR THIS SYSTEM AS IT IS MOVING ALONG A QUASI ZONAL FLOW IN A PATTERN SHIFT FOR THE MODELS. BUT AT THIS POINT...PLENTY OF MOISTURE IN COMBINATION WITH A RATHER COLD AIRMASS IS RESULTING IN SOME DECENT SNOW POSSIBILITIES FOR ALONG AND NORTH OF INTERSTATE 74...AND HPC IS PUTTING 2 TO 4 INCHES IN THAT NEIGHBORHOOD. BUT WILL RESTATE...ITS A FAST SYSTEM IN A PATTERN SHIFT AND ADJUSTMENTS TO THAT FORECAST ARE VERY MUCH LIKELY. && .ILX WATCHES/WARNINGS/ADVISORIES...
