The episode as NWS DVN wrote it up.
Strong low pressure in southeast Colorado moved to eastern Iowa during the early afternoon of November 22, 2010. The deepening cyclone then moved to northern Lake Michigan by evening. There was a tremendous thermal gradient with temperatures below zero in the northern Plains, with 60s and 70s from the southern Plains to Lower Michigan. A squall line formed in advance of the intense cold front impacting extreme eastern Iowa and western Illinois. Impressive deep layer shear and very strong wind fields triggered several intense supercells, especially in Illinois. Hail up to the size of hen eggs and winds in excess of 70 mph were reported in western Illinois during the afternoon. An intense supercell moved rapidly northeast at 60 mph across portions of southeast Henry county in western Illinois. This storm produced a swath of significant downburst wind damage from 1 mile south of Galva to 3 miles southeast of Kewanee. Trees were snapped or uprooted and several outbuildings damaged or destroyed. A NWS survey showed the damage swath was one-half mile wide in some areas. Wind speeds were estimated at 80 to 100 mph.

NWS Quad Cities, IA wrote its last area forecast discussion before the first event at Nov 21, 3:15 PM CST, 11 hours 5 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE QUAD CITIES IA IL 315 PM CST SUN NOV 21 2010 .SYNOPSIS... THE 12Z ANALYSIS HAD A DEEP 500MB TROF OVER THE WEST COAST WITH BROAD SWSLY FLOW INTO A RIDGE OVER THE EASTERN SEABOARD. WEAK S/W/S WERE EVIDENT IN THE SW FLOW THIS AFTERNOON. ONE WAS LIFTING THROUGH IA WITH ANOTHER OVER THE CENTRAL PLAINS. BROAD SWLY FLOW ALSO DOMINATED THE CENTRAL U.S. AT H8 THIS MORNING. THE SWLY FLOW WAS TRANSPORTING WARM DRY AIR NE INTO THE MID MS VALLEY WITH H8 TEMPS AROUND 16C CENTERED OVER MO. MUCH COLDER WAS LURKING JUST TO THE NW WHERE H8 TEMPS IN THE NEGATIVE TEENS COVERED MUCH OF ND AND MT. AT THE SURFACE AT 18Z LOW PRESSURE WAS LOCATED OVER NE IA WITH A WARM FRONT EXTENDING EAST INTO SRN WI AND A COLD FRONT TO THE SOUTH...DRAPED ACROSS NW MO AND CENTRAL. WARM SECTOR TEMPS WERE IN THE 60S TO AROUND 70 ACROSS ERN KS AND MO WITH MID 20S BEHIND THE FRONT IN EASTERN SD. PCPN OVER MID MS VALLEY ASSOCIATED WITH THIS SYSTEM SO FAR HAS BEEN MAINLY DRIZZLE DUE TO THE DRY MID LEVELS. && .SHORT TERM...TONIGHT AND MONDAY... TEMPS AND PCPN TRENDS WILL CONTINUE TO BE THE MAIN FOCUS OF THE FORECAST. THE DEEP SWLY FLOW OVER THE MIDWEST WILL KEEP THE FRONTAL BOUNDARY OVER THE REGION THROUGH MONDAY. THE SURFACE LOW OVER NE IA THIS AFTERNOON WILL CONTINUE NE ALLOWING THE COLD FRONT TO MOVE INTO NW IL THIS EVENING. ANOTHER SURFACE WAVE WILL LIFT NE ALONG THE BOUNDARY LATE TONIGHT AND MONDAY...PULLING THE FRONT BACK TO THE NW BEFORE IS SURGES BACK TO THE EAST MONDAY AFTERNOON AS THE SURFACE LOW MOVES INTO WI. THE TEMPERATURE FORECAST WILL CONTINUE TO BE DOMINATED BY MILD TEMPS ALONG AND EAST OF THE MISSISSIPPI RIVER THROUGH MONDAY. WILL KEEP MINS EAST OF THE RIVER MAINLY IN THE 50S WITH THE FRONT STAYING TO THE WEST WHILE LOWS OVER THE NW CWA SHOULD DIP INTO THE LOW 30S. DRY MID LEVELS WILL CONTINUE TO LIMIT ANY PCPN TO DRIZZLE OR VERY LIGHT RAIN AT LEAST THROUGH MIDNIGHT. AFTER MIDNIGHT LAPSE BEGIN TO STEEPEN ABOVE THE LOW LEVEL INVERSION. THE STEEPER MID LEVEL LAPSE RATES...COMBINED WITH MID-LEVEL FGEN SUPPORT MENTIONING RAIN CHANCES WITH POTENTIAL FOR ISOLATED THUNDER. MONDAY...WILL BE ANOTHER MID NOVEMBER DAY ALONG AND EAST OF THE MS RIVER WITH THE SURFACE FRONT REORIENTING ITSELF OVER EASTERN IA. HAVE CONTINUED TO MENTION HIGHS IN THE MID TO UPPER 60S BASED ON TEMPS LATE THIS AFTERNOON OVER MO. IF THESE TEMPS ARE REALIZED THEN THEY WOULD BE WITHIN A CATEGORY OF RECORD HIGHS AT KBRL /72 - 1913/ AND KMLI /69 - 1913/. MOISTURE WILL CONTINUE TO BE LIMITED TO THE LOW LEVELS SO WILL KEEP POPS IN THE CHANCE CATEGORY. FORECAST SOUNDINGS FOR KMLI/KBRL SHOW MID/LOW LEVEL LAPSE RATES STEEPENING AGAIN MONDAY AFTERNOON AROUND THE TIME OF THE COLD FROPA...SO WILL INCLUDE ISOLATED TSRA ALONG AND EAST OF THE RIVER. HAVE ALSO MENTIONED FOG TONIGHT INTO MONDAY MORNING...ANCHORED TO THE WEAKER GRADIENT ASSOCIATED WITH THE FRONT AS IT WOBBLES OVER THE REGION TONIGHT AND WITH THE NEXT SURFACE LOW MOVING THROUGH TOMORROW. ..DLF.. .LONG TERM...MONDAY NIGHT THROUGH NEXT SUNDAY... MONDAY NIGHT THROUGH TUESDAY NIGHT...AS SFC CYCLONE PROGRESSES ACRS THE EASTERN U.P. OF MI...WILL WALK OUT SOME LINGERING SHOWERS ALONG THE FROPA PROCESS OUT OF THE FAR EASTERN CWA MON EVENING ALTHOUGH FEEL BULK OF ACTIVITY WILL ALREADY BE CLEAR OF THE LOCAL FCST AREA BY 00Z TUE. MOST OF ANY DEVELOPING OR ONGOING THUNDERSTORMS ACTIVITY SHOULD BE MAINLY EAST OF THE DVN CWA BY 00Z. WILL ALSO BANK ON ANY CYCLONE WRAP AROUND PRECIP TO REMAIN NORTH OF THE DVN CWA MON EVENING ACRS SOUTHEAST MN AND WI...WITH INTRUDING CANADIAN RIDGE AXIS BECOMING THE DOMINANT FEATURE FROM THE NORTHERN PLAINS DOWN INTO THE MID MS RVR VALLEY. MUCH OF THE CWA TO DIP DOWN INTO THE 20S BY TUE AM WITH SOME CLOUD CLEAR OFF. SFC RIDGE TO BE THE MAIN FEATURE THE REST OF THIS PERIOD ACRS THE WESTERN GRT LKS...AS UPSTREAM L/W TROF BECOMES EDGY AND DIGS EASTWARD ACRS THE ROCKIES. TUE HIGHS TO RANGE FROM THE MID 30S NORTH...TO THE MID 40S IN THE SOUTH UNDER MOSTLY SUNNY SKIES...AND A CHILLY NIGHT IN STORE TUE NIGHT ALTHOUGH INCREASING CI AND EAST-SOUTHEAST GRADIENT RETURN FLOW LATE MAY TEMPER TRUE LOW TEMP POTENTIAL BY A CATEGORY. WEDNESDAY THROUGH THANKSGIVING THURSDAY...PREFER THE CONSISTENT ECMWF AND AGREEMENT WITH THE 12Z RUN NAM/THRU AT LEAST 84 HRS/ OF SLOWING EJECTING AND EVOLVING L/W TROF AND CLOSED UPPER CYCLONE SOME AS IT PULLS OUT ACRS THE NORTHERN PLAINS. THIS SCENARIO WOULD SUGGEST A SLOWER TOP-DOWN SATURATION PROCESS AND PRECIP DELAY... WITH MUCH OF WED POSSIBLE DRY AND LIGHT RAIN OR SPRINKLES DEVELOPING FROM MID AFTERNOON ON. THE MORE PROGRESSIVE AND QUICKER SATURATING GFS LINGERS LLVL COLD AIR ENOUGH FOR FREEZING RAIN AND SLEET TO IMPACT AREAS ALONG AND NORTH OF HWY 30 WED AFTERNOON. WILL THROW THIS SOLUTION OUT FOR NOW....AND GENERALLY FOLLOW THE PAST TWO ECMWF RUNS THROUGH THE REST OF THE FCST PERIOD. WILL CUT BACK POPS FROM WED MORNING AND OVERSPREAD LIGHT RAIN ACRS THE CWA WED AFTERNOON...MAINTAINING A MIX POSSIBLE IN THE NORTHWEST. THE FAVORED MODELS ALSO CONTINUE TO TREND WITH A SPLIT MODE INTO WED NIGHT...ONE SFC LOW TO THE LEE OR JUST NORTHEAST OF MAIN UPPER LOW ACRS NORTHWEST MN...AND THE OTHER UNDER STRONGLY DIFFLUENT MID LEVEL FLOW SKIRTING ALONG AND JUST SOUTHEAST OF THE DVN CWA THROUGH THU MORNING. THIS SOUTHERN SYSTEM WILL BE MORE IN LINE WITH INCREASING WARM MOIST CONVEYOR AND BE THE HIGHER QPF MAKER ACRS MO...THE SOUTH HALF OF IL AND UP THE NORTHERN OH RVR VALLEY. THIS LEAVES THE DVN CWA IN BETWEEN THE MORE ORGANIZED PRECIP MAKING PROCESSES...GENERALLY IN LIGHTER PRECIP BANDS OF MAINLY OVERRUNNING RAIN FROM 00Z-06Z THU. SFC TEMPS MAY CONTINUE TO RISE OR AT LEAST HOLD STEADY IN THE 40S WED EVENING ACRS THE BULK OF THE AREA JUST NORTH OF SOUTHERN LOW/S TRIPLE POINT. ELEVATED THUNDER MAY OCCUR IN THE SOUTHERN CWA WED EVENING. AS THE EXPECTED LLVL COLD CONVEYOR AND SUBSTANTIAL DRY SLOT SURGES SOUTH OF DEEPENING CLOSED UPPER LOW ACRS NORTH CENTRAL MN...A RAPID END TO THE PRECIP EXPECTED FROM WEST TO EAST AFTER MIDNIGHT WED NIGHT. SOME COOLING PROFILES INTERACTION WITH BACKSIDE OF PRECIP TO BRING ABOUT A BRIEF PERIOD OF POSSIBLE FREEZING RAIN AND SLEET...AND THEN A SWITCH OVER TO SNOW INTO EARLY THU MORNING. BUT EXPECT ANY ICE GLAZE OR SNOW AMOUNTS TO BE MINIMAL AT THAT POINT WITH BULK OF PRECIP HAVING EXITED THE LOCAL FCST AREA. THU STILL SHAPING UP TO BE SHARPLY COLDER AND BRISK/WINDY...WITH HIGH TEMPS HAVING TROUBLE ESCAPING THE UPPER 20S TO LOWER 30S TAKING INTO ACCOUNT THE ECMWF/S SUGGESTED INFLUX OF COLD CANADIAN AIR MASS. ALSO EXPECT MAINLY DRY CONDITIONS...BUT WILL STILL ADVERTISE THE LOW CHC FOR WRAP-AROUND SNOW SHOWERS IN THE NORTHEASTERN CWA FOR ONE MORE FCST CYCLE. WIND GUSTS COULD APPROACH 40 MPH WITH APPROPRIATE TROP-FOLD JUST SOUTHWEST OF RATHER INTENSE H5 MB LOW AND IT WILL BE INTERESTING IF SFC LOW CAN GO SUB-990 MB JUST NORTH OF LK SUPERIOR THU AFTERNOON...LIKE A FEW OF THE MEDIUM RANGE MODELS SUGGEST. EXTENT OF COLD THU NIGHT DEPENDENT ON CLEAR OUT AND SFC WIND DECOUPLE...BUT WIDESPREAD TEENS EXPECTED EVEN WITH SFC WINDS MAINTAINING AROUND 10 KTS DO TO EXTENT OF CAA. FRIDAY THROUGH SUNDAY...UPPER RIDGING PROGGED BY ENSEMBLES TO AMPLIFY AND BUILD ACRS THE MID CONUS THIS PERIOD FOR A BLOCKED BUT FAIR WX PATTERN FOR MUCH OF THE MIDWEST. THERMAL MODERATION LOOKS TO BE SLOWER WITH LATEST 12Z RUNS...BUT STILL EXPECT HIGHS WELL UP INTO THE 40S BY SUNDAY. COLD START TO THE DAY AND LINGERING LLVL COLD POOL MAY KEEP FRI HIGHS IN THE LOWER 30S EVEN WITH A GOOD DURATION OF INSOLATION AND SNOW COVER-LESS GROUND. MODERATION INTO SAT FOR HIGHS IN THE UPPER 30S TO LOWER 40S. ..12.. && .AVIATION... A COLD FRONT FROM NEAR KMIW THROUGH KTOP WILL MOVE EAST AND STALL NEAR THE MS RIVER THIS EVENING THE FRONT WILL THEN PUSH BACK TO THE NORTH AND WEST LATE TONIGHT AND MONDAY MORNING. CONDITIONS AHEAD OF THE FRONT HAVE IMPROVED TO MAINLY VFR WITH SOME MVFR CIGS/VSBYS STILL IMPACTING KCID. EXPECT CONDITIONS TO DETERIORATE AGAIN TO IFR THIS EVENING AS THE FRONT MOVES EAST AND THE PRESSURE GRADIENT AROUND THE FRONT WEAKENS. IFR/LIFR CONDITIONS ARE EXPECTED BY MIDNIGHT. DENSE FOG WILL BE POSSIBLE LATE TONIGHT AND MONDAY MORNING NEAR THE FRONTAL BOUNDARY IN EASTERN IA AND NW IL. PCPN THROUGH THIS EVENING SHOULD BE SPOTTY AND LIMITED TO DRIZZLE. SOME SCT SHRA LATE TONIGHT AND MONDAY MORNING. ISOLD TSRA WILL BE POSSIBLE NEAR AND EAST OF THE MS RIVER. CONDITIONS ALONG AND EAST OF THE MS RIVER WILL GRADUALLY IMPROVE TO MVFR CONDITIONS BY LATE MONDAY MORNING AHEAD OF ANOTHER SURFACE LOW LIFTING NE OUT OF MO. ..DLF.. && .DVN WATCHES/WARNINGS/ADVISORIES...
