The episode as NWS DVN wrote it up.
Heavy rains resulted in some flash flooding in Milan, IL during the afternoon hours of July 10.
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 Quad Cities, IA wrote its last area forecast discussion before the first event at Jul 10, 2:20 AM CST, 9 hours 45 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE QUAD CITIES IA IL 320 AM CDT FRI JUL 10 2009 .SYNOPSIS... LATEST SFC ANALYSIS WAS INDICATING THE MAIN UPSTREAM COOL FRONT EXTENDING NNE-TO-SSW ACRS CENTRAL AND SOUTHWEST MN...SOUTHEAST SD AND CENTRAL NEB. A SFC LOW WAS TRYING TO DEVELOP ACRS NORTH CENTRAL KS...WITH ATTENDANT WARM FRONT EXTENDING EASTWARD ALONG AND SOUTH OF THE IA/MO BORDER. 00Z UA ANALYSIS WAS INDICATING A SUBSTANTIAL LOW TO MID LEVEL WARM DOME OVER THE SOUTHERN AND CENTRAL PLAINS...SW IA AND MUCH OF WESTERN MO. ALOFT...WV IMAGERY WAS INDICATING A SWIRLING VORT OVER THE NEB/WESTERN IA BORDER. && .SHORT TERM...TODAY AND TONIGHT... CHALLENGING FCST CONTINUES INTO TODAY AND TONIGHT ALL VERY DEPENDANT ON MCS CONTINUATION OR REDEVELOPMENT ON CONVECTIVE REMNANTS AS THE DAY PROGRESSES. NOWCAST TOOLS AND ASSESSING THE CONTINUING 30-40 KT SOUTHWESTERLY LLJ WITH A HIGH THTA-E FEED UP AND OVER THE LLVL WARM FRONT ALONG AND SOUTH OF THE DVN CWA...EXPECT THE ELEVATED MCS CURRENTLY ALONG THE IA/MN BORDER AND OVER NORTHEAST IA TO FESTER ACRS THE NORTHERN THIRD OF THE CWA/EDGE OF CAP THROUGH AT LEAST MID MORNING. ALTHOUGH EXPECT LOCALLY HEAVY RAINFALL AT INTENSE RATES AND POSSIBLY SOME LOCALIZED URBAN/SMALL STREAM OR EVEN FLASH FLOODING... TIME OF DAY AND ELEVATED NATURE TO THE SYSTEM MAY LIMIT SVR POTENTIAL. WBZ/S AND FZ LEVELS A BIT HIGH FOR SVR SIZE HAIL AS WELL. THE OTHER ASPECT WILL BE WATCHING FOR DEVELOPMENT OVER THE NEXT FEW HOURS OVER SOUTHWEST INTO CENTRAL IA IN VIEW OF OPTIMUM LLVL CONVERGENCE ON NOSE OF LLJ AND APPROACHING NEB VORT...WHICH WOULD EVENTUALLY TRANSLATE ACRS THE SOUTH HALF OF THE DVN CWA THROUGH MUCH OF THE MORNING AND MIDDAY. IF THIS SOUTHERN ACTIVITY DOES NOT MATERIALIZE...A BETTER CHANCE FOR THE SOUTHERN FRINGE OF THE NORTHEASTERN IA MCS REMNANTS TO FLARE UP AND STRENGTHEN AS THE DAY PROGRESSES/POSSIBLY TO SVR LEVELS/ OVER THE CENTRAL AND SOUTHERN CWA AND INTO IL. THIS AFTERNOON AND EVENING...WILL HAVE TO WATCH FOR REDEVELOPMENT ON CONVECTIVE DEBRIS OR LINGERING OUTFLOW BOUNDARIES... OR THE LARGE SCALE APPROACHING COOL FRONT ITSELF. UKMET MCS-FORCING TOOLS WHICH ARE DOING WELL NOW...SUGGEST THE BEST MCS SPAWNING GROUNDS THIS EVENING ALONG AND JUST EAST OF THE DVN CWA ACRS MUCH OF NORTHERN IL. MAY HAVE SOME INITIAL STORM DEVELOPMENT RIGHT OVER HEAD...SOME OF WHICH WOULD BE SVR IF WE CAN GET SOME AFTERNOON RECOVERY/INSTABILITY BUILD UP AFTER THE MORNING ACTIVITY. THEN THIS CONVECTION WOULD EVOLVE INTO AN MCS ACRS THE NORTH HALF OF IL OVERNIGHT. THE OTHER SCENARIO WOULD BE DEVELOPMENT OVER THE SOUTH HALF OF THE DVN CWA ON BOUNDARY REMNANTS AND RENEWED LLJ CONVERGENCE. WILL HOLD OFF A FLASH FLOOD WATCH FOR NOW...BUT PW IN-FEED OF 1.8 TO OVER 2 INCHES IMPRESSIVE AND WOULD SUPPORT HIGH RAINFALL RATES OF OVER 2 INCHES/HR AND LOCALIZED FLASH FLOODING. DEPENDING ON HOW MUCH RAINFALL OCCUR THIS MORNING AND TODAY...THE FOLLOWING SHIFT MAY HAVE TO ISSUE A WATCH FOR TONIGHT FOR ANY NEW DEVELOPMENT. TEMPS HIGHLY DEPENDANT ON CONVECTIVE DEBRIS AND WILL JUST TRY TO COVER THE MEDIUM RANGE OF POSSIBILITIES BUT TREND TOWARD THE COOLER SIDE BANKING ON CLOUD COVER AND STORM OUTFLOW. MAY STILL BE TOO WARM WITH HIGHS IF NO AFTERNOON RECOVERY OCCURS. IF WE CLEAR OUT THOUGH... FCST HIGHS IN THE LOW TO MID 80S WITH LOW 70 SFC DPTS SUPPORTS CAPES OF 2500-3K J/KG AND DAMAGING WIND THREAT...WITH SOME MID LEVEL FLOW OF 40-50 KT ENTRAINMENT DOWNWARD. ..12.. .LONG TERM...SATURDAY THROUGH NEXT THURSDAY... MESSY LONG TERM THIS MORNING...BUT WITH IMPROVING MODEL CONSISTENCY OVER THE PAST FEW DAYS. COLD FRONT SAGS SOUTH OF THE FORECAST AREA SATURDAY MORNING...BUT WITH CONTINUING NORTHWEST FLOW ALOFT OVER THE REGION. THIS MEANS THAT THE BOUNDARY WILL NOT BE SAGGING OVERLY FAR TO THE SOUTH...AND REMAINS NEARBY ENOUGH TO KEEP POPS IN THE AREA THROUGH SATURDAY...MAINLY ACROSS THE SOUTH PORTIONS OF THE FORECAST AREA. SUNDAY IT APPEARS THAT THERE WILL BE A LULL IN THE CONVECTIVE ACTIVITY AS AN MCS MOVES EAST ACROSS ILLINOIS AND INDIANA SUNDAY MORNING. MORE ACTIVITY DEVELOPS FOR SUNDAY NIGHT AND MONDAY. THERE IS MUCH DISAGREEMENT ON THE TIMING AND PLACEMENT OF THIS ACTIVITY...WITH REALLY ONLY THE NAM PRODUCING PRECIPITATION ACROSS THE AREA OVERNIGHT. THE GFS AND ECMWF ARE KEEPING IT TO THE SOUTHWEST. HOWEVER WITH THE BOUNDARY JUST TO OUR SOUTHWEST... SHOWERS AND THUNDERSTORMS ARE QUITE PLAUSIBLE...AND HAVE MAINTAINED THE LOW END CHANCE POPS THAT WE ALREADY HAD GOING IN THE FORECAST ACROSS THE SOUTH HALF OF THE FORECAST AREA. SATURDAY THROUGH MONDAY TEMPERATURES REMAIN ON THE COOL SIDE WITH THE BOUNDARY TO OUR SOUTH...WITH INCREASED CLOUDINESS DUE TO THE SHOWERS AND THUNDERSTORMS. MONDAY NIGHT SHOULD BE QUIET AGAIN AS A NEW SYSTEM DEVELOPS OUT IN THE PLAINS. THE UPPER LEVEL WAVE ASSOCIATED WITH THIS IS A FAIRLY POTENT SHORTWAVE THAT WILL HAVE BEEN ROLLING ACROSS THE NORTHWEST STATES SINCE SUNDAY EVENING...SO WE NEED TO WATCH FOR IT LATER THIS WEEKEND AS IT BEGINS TO MOVE INTO THE UPPER AIR NETWORK. A FAIRLY STRONG SURFACE LOW DEVELOPS OVER SOUTH DAKOTA AND ROLLS EAST INTO SOUTHERN MINNESOTA AND WISCONSIN BY TUESDAY NIGHT...AND SHOULD MANAGE TO FIRST PUSH A WARM AIR ADVECTION WING OF PRECIPITATION ACROSS THE AREA EARLY TUESDAY...FOLLOWED BY A COLD FRONT ON TUESDAY NIGHT. HAVE KEPT CHANCE POPS FOR BOTH PERIODS...THOUGH IF CONSISTENCY CONTINUES TO BE GOOD...WE CAN RAISE POPS. TUESDAY WE SHOULD BE IN THE WARM SECTOR OF THIS SYSTEM AND TEMPERATURES BACK ABOVE NORMAL SHOULD REMIND US THAT IS IS ACTUALLY JULY. WEDNESDAY AND THURSDAY APPEAR QUIET FOR NOW ON THE HEELS OF THIS SYSTEM...WITH A BOUNDARY DEPRESSED SOUTH TO THE LOWER OHIO VALLEY AND BACK ACROSS TO SOUTHWEST MISSOURI BY WEDNESDAY EVENING. WITH THE BOUNDARY SOUTH AGAIN...TEMPERATURES WILL BE BACK BELOW NORMAL AGAIN. ..LE.. && .AVIATION... POTENTIALLY A HIGH AVIATION IMPACT DAY DO TO ROUNDS OF CONVECTION AT ALL TERMINALS. STORM COMPLEX TO IMPACT THE DBQ AND CID TERMINALS THIS MORNING...WITH 1 1/2-5SM VSBYS FROM FOG SOUTH OF THE STORMS THROUGH 13Z. MAY BE SOME AFTERNOON REPRIEVE FROM STORMS BUT LINGERING MVFR AND LOWER LEVEL VFR CLOUD DEBRIS...AND WILL HAVE TO WATCH OUT FOR NEW STORM DEVELOPMENT...POSSIBLY AT SVR LEVELS AFTER 22Z ESPECIALLY IN THE VCNTY OF MLI AND BRL. ..12.. && .DVN WATCHES/WARNINGS/ADVISORIES...

IF THIS STORM SYSTEM CAN MAINTAIN ITS STRENGTH...IT MAY BE ABLE TO PRODUCE STRONG WINDS AND HAIL AS FAR SOUTH AS THE INTERSTATE 80 CORRIDOR THROUGH LATE MORNING. OTHER STORMS MAY DEVELOP IN SOUTH CENTRAL IOWA EARLY THIS MORNING AND EVENTUALLY MOVE ACROSS AREAS SOUTH OF INTERSTATE 80 THROUGH MIDDAY. IF THIS OCCURS...THESE STORMS WOULD ALSO HAVE THE POTENTIAL TO PRODUCE WIND GUSTS OF 45 TO 60 MPH AND HAIL UP TO THE SIZE OF QUARTERS. VERY HEAVY RAINFALL AT RATES OF UP TO 2 INCHES AN HOUR MAY PRODUCE LOCALIZED URBAN AND SMALL STREAM FLOODING AS THESE STORMS PASS THROUGH. AS FOR THE STORM POTENTIAL FOR THIS AFTERNOON AND EVENING...MUCH WILL DEPEND ON HOW MUCH THE ATMOSPHERE CAN RECOVER AND HEAT UP AFTER THE MORNING STORMS EITHER MOVE OUT OF THE AREA OR FALL APART. IF SOME SUNSHINE CAN BREAK OUT FOR TEMPERATURES TO WARM INTO THE 80S...A VERY UNSTABLE AIRMASS WILL BECOME ESTABLISHED ACROSS THE REGION. THEN A COLD FRONT APPROACHING FROM THE WEST SHOULD TRIGGER THUNDERSTORMS BY THIS EVENING. WITH DEEP LAYER SHEAR AND STRENGTHENING MID LEVEL WINDS THERE WILL BE A THREAT FOR SUPERCELL TYPE THUNDERSTORMS WITH DAMAGING WINDS...LARGE HAIL AND A FEW TORNADOES DEVELOPING IN THE OUTLOOK AREA. WIDESPREAD DAMAGING WINDS IN EXCESS OF 70 MPH WILL BECOME THE PRIMARY THREAT IF THE INITIAL STORMS FORM INTO A LINE DURING THE EVENING. LATEST INDICATIONS SUGGEST THAT THIS LINE OF STORMS WILL MAINLY IMPACT AREAS ALONG AND EAST OF THE MISSISSIPPI RIVER TONIGHT. LOCALLY HEAVY RAINFALL WILL AGAIN BE LIKELY WITH ANY STRONG STORMS...AND COMBINED WITH THE RECENT BOUTS OF RAIN MAY CAUSE FLASH FLOODING DUE TO SATURATED SOILS. MANY AREA RIVER AND STREAMS WILL ALSO EXPERIENCE SUBSTANTIAL RISES. THE STORM PREDICTION CENTER HAS THE ENTIRE OUTLOOK AREA UNDER A SLIGHT RISK FOR SEVERE WEATHER TODAY AND TONIGHT. .DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY THUNDERSTORMS MAY BE ONGOING OVER PORTIONS OF THE OUTLOOK AREA SATURDAY MORNING ESPECIALLY ALONG AND SOUTH OF INTERSTATE 80. THERE IS A LOW CHANCE THAT A FEW STORMS WILL RE-STRENGTHEN AND REACH SEVERE LIMITS ALONG AND SOUTH OF THE HIGHWAY 34 CORRIDOR. LATEST INDICATIONS THEN SUGGEST THAT THE NEXT MAIN CHANCE FOR THUNDERSTORMS AFTER THE WEEKEND WILL BE LATE TUESDAY AND TUESDAY NIGHT. IT IS STILL TOO EARLY TO DETERMINE THE THREAT FOR SEVERE WEATHER FOR TUESDAY. .SPOTTER INFORMATION STATEMENT... SPOTTER ACTIVATION IS LIKELY TODAY AND TONIGHT. 12

...STRONG WINDS POSSIBLE BEHIND DEPARTING STORMS...
A LINE OF SHOWERS AND THUNDERSTORMS WILL CONTINUE MOVING THROUGH EASTERN IOWA
THROUGH THIS AFTERNOON. WIND GUSTS TO 50 MPH ARE POSSIBLE BEHIND THE SHOWERS
AND THUNDERSTORMS AS THEY EXIT THE AREA. THESE WINDS COULD OCCUR WELL AFTER
THE HEAVIEST RAIN HAS ENDED. WIND GUSTS TO NEAR 50 MPH HAVE ALREADY BEEN
REPORTED NEAR VAN HORNE IOWA...IN BENTON COUNTY.
LOCATIONS FROM INDEPENDENCE AND MANCHESTER...SOUTH TO IOWA CITY AND
WILLIAMSBURG COULD BE EFFECTED BY THESE WINDS.
STRONG GUSTY WINDS WILL MAKE DRIVING DIFFICULT...ESPECIALLY FOR HIGH
