The episode as NWS HUN wrote it up.
A long-lived mesoscale convective system that contained heavy rain and thunderstorms enveloped the region during the late evening and overnight hours. 24 hour rainfall amounts from this system reached 3 to over 5 inches. Runoff and flash flooding from the heavy rainfall began during the late evening on the 29th and lasted through the morning hours of the 30th. The runoff pushed a few small creeks and streams out of their banks, flooding some roads, and submerging a school bus in high water. Fortunately, no students were on the bus at the time. Several county schools were delayed due to the high water and impassible roadways.
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 30, 5:58 AM CST, 1 hour 2 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE HUNTSVILLE AL 558 AM CST TUE NOV 30 2010 .UPDATE...FOR 12Z TAFS. && .AVIATION... MVFR CIGS AND VSBYS CONTINUE WITH TSRA BEING REPORTED AT KHSV. EXPECT THE POSSIBILITY OF TSRA TO CONTINUE THROUGH 13Z AT KHSV. EXPECT -SHRA OR VCSH AT BOTH TERMINALS THROUGH 6 PM. CIGS WILL BE VARIABLE THROUGH 19Z RANGING FROM VFR TO MVFR...WITH IFR POSSIBLE IN PERIODS OF HEAVIER RAINFALL AT KHSV. DIP BACK INTO THE MVFR REALM AT TIMES THROUGH 19Z AT KMSL AND A LITTLE LATER AT KHSV. VFR CONDITIONS SHOULD RETURN TO BOTH LOCATIONS BY 6 PM. && .PREV DISCUSSION... /ISSUED 444 AM CST TUE NOV 30 2010/ DISCUSSION... A LINE OF SHOWERS AND THUNDERSTORMS CONTINUED TO TRAIL ACROSS THE TENNESSEE VALLEY ALONG THE SURFACE FRONTAL BOUNDARY...EXTENDING FROM NORTH OF HATTIESBURG MS TO TUSCALOOSA AL TO CHATTANOOGA TN TO KNOXVILLE TN. THE INITIAL PUSH OF COLD AIR IS ALIGNED WITH THE 850MB BOUNDARY WHICH IS FURTHER WEST AND JUST REACHING THE MISSISSIPPI RIVER. STILL FURTHER WEST NEAR THE ARK-OK BORDER ALIGNED WITH THE 700MB FRONT IS THE BACK EDGE OF THE CLOUD DECK AND THE STRONGER SHOT OF COLD AIR. THE PASSAGE OF THIS COLD FRONT IS THE BIG STORY FOR THE FORECAST PACKAGE TODAY. MODELS SEEM TO BE RUNNING ABOUT 6 HOURS SLOW ON THE EASTWARD PROGRESSION OF THE PRECIPITATION LINE. WHILE A WIDE SWATH OF STRATIFORM RAIN CONTINUES TO SLIDE NORTHEAST IN A REGION OF BROAD MIDLEVEL ISENTROPIC UPGLIDE...WOULD EXPECT TO SEE PRECIPITATION START CLEARING THE WESTERN EDGE OF THE CWA BY 00Z TONIGHT. WITH THIS FASTER PACE TO THE SYSTEM...HAVE REMOVED PRECIP WORDING AFTER MIDNIGHT FROM THE ENTIRE CWA AND ONLY A SHORT PERIOD FROM 00-06Z MENTIONING A MIX OF SNOW AND RAIN IN THE HIGHER ELEVATIONS. MODEL SOUNDINGS INDICATE THE END OF PRECIP WILL OCCUR VERY CLOSE TO THE SAME TIME AS THE ENTIRE COLUMN GOING BELOW FREEZING...SO THE CHANCE OF A CHANGEOVER WILL BE IN A VERY FINE LINE. AFTER TONIGHT...THE COLD AIR WILL BRING WELL BELOW NORMAL TEMPERATURES ONLY FOR A COUPLE OF DAYS BEFORE A SLOW WARMUP OCCURS. THE WEEKEND LOOKS TO BE SEASONABLE AS HIGH PRESSURE MOVES ACROSS THE CENTRAL AND EASTERN CONUS. THEN FOR THE BEGINNING OF NEXT WEEK...MODEL SOLUTIONS CONTINUE TO DIVERGE IN THEIR HANDLING OF THE NEXT SYSTEM. THE GFS IS A LITTLE MORE PROGRESSIVE THAN THE ECMWF STILL...AND BRINGS ANOTHER LOW WITH SOME RAIN LATE ON SUNDAY AND MONDAY AND WRAP-AROUND PRECIP ON MONDAY-TUESDAY. DUE TO THE LACK OF CONSISTENCY IN HANDLING THIS SYSTEM...WENT WITH SILENT POPS FOR THE MAJORITY OF THE LATE WEEKEND AND EARLY NEXT WEEK. MOST MODELS TO HINT AT VERY CHILLY AIR PUSHING IN FOR EARLY NEXT WEEK THOUGH...SO STARTED TRENDING TEMPS IN THAT DIRECTION. && .HUN WATCHES/WARNINGS/ADVISORIES... AL...NONE.
