The episode as NWS HUN wrote it up.
A quasi-linear convective system consisting of a broken line of low-topped showers with no lightning tracked southeast along a strong cold front. The temperature contrast on either side of the front was 25-35 degrees. Despite limited convective instability, strong low level wind shear provided a favorable environment for low level meso-cyclones to develop with the stronger cells, despite shallow updrafts consisting of no lightning activity. One of the cells during the late evening developed a pronounced meso-cyclone which produced a narrow path of damage in the Dutton (Jackson County) and Ider (DeKalb County) areas.
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 Huntsville, AL wrote its last area forecast discussion before the first event at Nov 25, 7:21 PM CST, 3 hours 11 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE HUNTSVILLE AL 721 PM CST THU NOV 25 2010 .DISCUSSION...COLD FRONT PUSHING THROUGH NW AL AS OF 01Z THIS EVENING. LATEST RADAR IMAGERY SHOWING A BROKEN LINE OF MAINLY SHRA JUST ALONG/BEHIND THE SFC FRONT FROM MIDDLE TN THROUGH NW AL INTO CENTRAL MS. DISCRETE SHOWERS HAVE SHOWN TRANSIENT ROTATIONAL FEATURES OVER THE LAST SEVERAL HOURS...AND THIS IS NOT SURPRISING BASED ON STRONG LOW LEVEL SHEAR EVIDENT IN 00Z OHX/BNA HODOGRAPH AND SPC MESOANALYSIS TRENDS. HAVING SAID THAT...IT'S VERY POSSIBLE THAT THE ROTATIONAL FEATURES ARE SLIGHTLY ELEVATED ABOVE THE BLYR...AND THE CELLS THEMSELVES ARE CERTAINLY SHALLOW IN NATURE WITH TOPS NOT EXCEEDING ~20KFT. CLASSIC ANAFRONT SETUP WILL LEAD TO A FAIRLY PROLONGED PERIOD OF LIGHT/MOD RAIN AFTER FROPA THIS EVENING...AND THIS WILL MAKE FOR A FAIRLY MISERABLE OVERNIGHT PERIOD AS TEMPS CRASH HARD/QUICKLY. TEMPS ARE ALREADY DOWN INTO THE 40S ACROSS WRN TN AND INTO THE UPPER 30S IN NE AR. QUICK REVIEW OF BUFR SOUNDINGS AND THERMAL PROFILE TRENDS DO SHOW THAT MOST OF THE PRECIP SHOULD BE OUT OF THE AREA BEFORE THE THERMODYNAMIC COLUMN IS SUFFICIENTLY COLD/DEEP TO SUPPORT WINTER PRECIP. LARGE SCALE PRESSURE RISES BEHIND THE FRONT WILL ALSO LEAD TO A RATHER GUSTY PERIOD OF NRLY/NWRLY WINDS ACROSS THE TN VLY OVERNIGHT. HAVE BUMPED WINDS UP ACCORDINGLY IN THE GRIDS. OTHERWISE...NO MAJOR CHANGES HAVE BEEN MADE TO THE FCST JUST MINOR ADJUSTMENTS TO ACCOUNT FOR CURRENT FRONT/RADAR TRENDS. && .AVIATION...COLD FRONT TO SWEEP ACROSS THE TN VLY THIS EVENING. GENERALLY VFR CONDITIONS BEING EXPERIENCED IN THE WARM SECTOR AHEAD OF THE FRONT. HOWEVER...EXPECT CONDITIONS TO DETERIORATE SOMEWHAT THROUGH THE EVENING WITH FROPA. INCLUDED MVFR CIGS/VSBY AFT FRONTAL PASSAGE WITH SHRA ACTIVITY ANTICIPATED. GUIDANCE SUGGESTS FAIRLY LOW CIGS TO HANG ON THROUGH MID MORNING FRIDAY. ALSO...WINDS MAY BE A BIT GUSTY FROM THE NORTH BEHIND THE FRONT. && .DISCUSSION... /ISSUED 334 PM CST THU NOV 25 2010/ PRIMARY FORECAST CONCERN THIS AFTERNOON CENTERS AROUND APPROACHING LINE OF CONVECTION TO OUR WEST. THE LATEST ANALYSIS SHOWS A SYNOPTIC COLD FRONT ALIGNED FROM NORTHWEST OH...TO JUST WEST OF MEMPHIS...TO EAST CENTRAL TX. THE THERMAL BOUNDARY WAS FAIRLY STRONG WITH THIS FRONT...WITH A 2PM TEMP OF 70F AT MEM...AND 46F AT LITTLE ROCK, AR. SOUTH TO SOUTHWEST SFC FLOW AHEAD OF THE FRONT HAS BEEN STRONG TODAY WITH GUSTS AROUND 35 MPH AT TIMES...WHICH PROMPTED THE ISSUANCE OF A WIND ADVISORY EARLIER. WILL CONTINUE TO LET THE ADVISORY RIDE THROUGH 00Z. BECAUSE THE WINDS HAVE A DECENT SW COMPONENT...THE DIRECTIONAL SHEAR IS NOT QUITE AS STRONG AS FORECAST. NEVERTHELESS...DIRECTIONAL SHEAR IS SIGNIFICANT AND SHOULD INCREASE A LITTLE FURTHER AS THE FRONT APPROACHES AND A LEADING LOW-LVL SPEED MAX MOVES ACROSS THE AREA THIS EVENING. RESULTING SHEAR VALUES CURRENTLY WERE STRONG ENOUGH TO PROMPT THE ISSUANCE OF A SVR TSTM WATCH JUST TO OUR WEST...BORDERING OUR NW ALABAMA COUNTIES...AND THIS WATCH WILL LAST THROUGH 7PM CST. WITH THE LOSS OF DAYTIME HEATING...WHAT LITTLE INSTABILITY THAT WAS PRESENT TODAY WILL DIMINISH. ALTHOUGH...SHEAR WILL REMAIN RATHER HIGH AS THE LINE OF CONVECTION MOVES ACROSS THE AREA. A FEW STRONG OR PERHAPS SEVERE SHORT-LIVED CELLS MAY STILL BE POSSIBLE THIS EVENING...MAINLY IN NORTHWEST ALABAMA. THE BEST TIMING AVAILABLE ATTM...PLACES THE LEADING EDGE OF THE MAIN LINE OF CONVECTION IN THE MUSCLE SHOALS AREA BY ABOUT 7 PM...HUNTSVILLE ARND 9PM...AND FT PAYNE ARND 11 PM. THE PRIMARY CONVECTIVE MODE WILL CONTINUE TO FAVOR A LINE OF STORMS...BUT SOME EMBEDDED ROTATING CELLS WILL BE POSSIBLE. IN PARTICULAR...THE CELLS OUT JUST AHEAD OF THE LINE AND THOSE THAT MERGE WITH THE LINE WILL BEAR THE MOST WATCHING...AS USUAL. WHILE AN ISOLATED SHORT-LIVED TORNADO CANNOT BE RULED OUT...THE MAIN THREAT WILL CONTINUE TO BE DAMAGING WIND GUSTS. BUT AGAIN...THE OVERALL THREAT APPEARS SLIGHT AT THIS TIME. AS THE COLD FRONT ITSELF MOVES ACROSS THE AREA...TEMPS WILL DROP VERY MARKEDLY. BY MORNING...TEMPERATURES ARE LIKELY TO BE IN THE MID 30S IN THE WEST...WITH MID 40S POSSIBLY HANGING ON IN THE EAST. NORTHWEST WINDS WILL BE AROUND 10-15 MPH WITH GUSTS TO PERHAPS 20MPH AT TIMES...MAKING CONDITIONS FEEL EVEN COLDER. A FEW SHOWERS WILL LINGER BEHIND THE FRONT AS WELL. BASED ON FCST SOUNDINGS AND TOP-DOWN APPROACH...ANY FRZN PRECIP DOES NOT APPEAR LIKELY. A BRIEF SHOWER OF ICE PELLETS COULD OCCUR THOUGH IN THE HIGHEST TERRAIN IN THE EAST EARLY FRI MORNING...BUT CHANCE APPEARS SO SLIGHT AS TO NOT WARRANT MENTION IN THE OFFICIAL FORECAST AT THIS TIME THOUGH. FOR ANY EARLY MORNING SHOPPERS...BE PREPARED TO DRESS WARMLY IN LAYERS...ESPECIALLY IF YOU WILL BE OUTDOORS FOR SOME EXTENDED PERIOD. CLOUDS WILL GRADUALLY CLEAR FROM WEST TO EAST ON FRIDAY...BUT COLD AIR ADVECTION WILL KEEP TEMPS SUPPRESSED. HIGHS DURING THE AFTERNOON WILL STRUGGLE TO REACH THE MID 40S. WITH A CLEAR SKY AND QUICKLY DECREASING WIND SPEEDS...LOW TEMPS ON SAT MORNING WILL LIKELY BE IN THE MID/UPR 20S. SO...A WIDESPREAD HARD FREEZE APPEARS POSSIBLE. TEMPERATURES WILL MODERATE INTO THE WEEKEND AND CONDITIONS WILL REMAIN DRY AS A WEAK UPR RIDGE PASSES ACROSS THE SOUTHEAST. BY EARLY NEXT WEEK...A HIGH AMPLITUDE TROUGH AND VIGOROUS UPR WAVE WILL DIG INTO THE CENTRAL CONUS. WIND DYNAMICS APPEAR TO BE SIMILARLY STRONG IF NOT STRONGER WITH THIS NEXT SYSTEM...SO ITS EVOLUTION WILL BEAR SOME WATCHING OVER THE NEXT FEW DAYS. GIVEN THE SHEAR POTENTIAL...HAVE MENTIONED STRONG/SVR TSTM POTENTIAL IN THE HWO PRODUCT FOR MONDAY AND TUESDAY. ADDITIONALLY...GIVEN THE DEEP TROPICAL FETCH AND RELATIVELY HIGH MOISTURE AVAILABILITY...HEAVY RAIN APPEARS POSSIBLE WITH THIS SYSTEM. TIMING REMAINS UNCERTAIN...THUS THE EXTENDED PERIOD OF ACTIVITY CURRENTLY FCST FROM MONDAY THROUGH TUESDAY NIGHT. THE WINDOW FOR SHRA/TSTMS WILL BE NARROWED AS CONFIDENCE IN TIMING INCREASES. && .HUN WATCHES/WARNINGS/ADVISORIES... AL...NONE. TN...NONE. && DISCUSSION...15

WIDESPREAD SHOWERS ALONG WITH A FEW THUNDERSTORMS WILL CONTINUE TO PUSH EAST ACROSS THE TENNESSEE VALLEY ALONG A PASSING COLD FRONT TONIGHT. WITHIN THE LARGER LINE OF SHOWERS AND STORMS...AN ISOLATED STRONG TO SEVERE STORM IS NOT OUT OF THE QUESTION. THE MAIN THREAT WITH ANY STRONGER STORMS WOULD BE GUSTY WINDS TO AROUND 50 MPH. SHARPLY COLDER TEMPERATURES AND CLEARING CONDITIONS ARE EXPECTED LATE TONIGHT BEHIND THE FRONT. .DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY... ANOTHER STRONG DISTURBANCE WILL MOVE ACROSS THE AREA ON MONDAY AND TUESDAY OF NEXT WEEK. A LINE OF THUNDERSTORMS IS EXPECTED WITH THE COLD FRONT...AND SOME OF THESE STORMS COULD BECOME SEVERE. .SPOTTER CALL TO ACTION STATEMENT... ACTIVATION OF STORM SPOTTERS AND EMERGENCY MANAGEMENT PERSONNEL IS NOT ANTICIPATED AT THIS TIME.
