The episode as NWS HUN wrote it up.
An isolated strong thunderstorm developed during the early afternoon and downed a tree on a power line in Madison County.
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 Jul 8, 12:18 PM CST, 22 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE HUNTSVILLE AL 118 PM CDT SUN JUL 8 2012 .DISCUSSION... ANOTHER VERY WARM AND HUMID AFTERNOON IN PROGRESS ACROSS THE TENNESSEE VALLEY. AT 1 PM...TEMPERATURES RANGED FROM 90 TO 95 DEGREES IN MOST LOCATIONS. VISIBLE IMAGERY SHOWS A LARGE EXPANSE OF CUMULUS COVERING ALL BUT FAR NW ALABAMA WITH SOME MORE ENHANCED CONVECTIVE ELEMENTS NOTED...PRIMARILY EAST OF INTERSTATE 65. EARLY AFTERNOON SFC ANALYSIS SHOWS AN ELONGATED FRONT STRETCHING FROM THE DELMARVA WESTWARD ACROSS THE LOWER OHIO RIVER VALLEY INTO THE TEXAS PANHANDLE. LIGHT SERLY FLOW ACROSS THE TN VLY HAS ALLOWED LOW LEVEL MOISTURE TO CREEP UP APPRECIABLY OVER THE LAST SEVERAL DAYS WITH DEWPOINTS AROUND 70F AREAWIDE. THIS HAS ALLOWED SBCAPES TO REACH THE 2-2.5 KJ/KG RANGE THIS AFTERNOON. ALTHOUGH OVERALL FORCING IS WEAK CURRENTLY...ISOLD CONVECTION HAS DEVELOPED ACROSS THE REGION. A WEAK S/W TROUGH (AKIN TO A SHEAR AXIS) WAS POSITIONED FROM SRN MS INTO FAR WRN AL. THIS MAY HELP TO SUSTAIN (EVEN ENHANCE) CONVECTION THROUGH THIS EVENING. THE NAM/HRR SHOW LITTLE CONVECTIVE DEVELOPMENT THROUGH EVENING WHILE SEVERAL ITERATIONS OF THE HIGH RES WRF SHOW SCT DEVELOPMENT SOUTH OF THE SFC FRONT/EAST OF THE SHEAR AXIS ACROSS THE TN VLY. THE SFC FRONT WILL DRIFT/ADVANCE EVER SO SLOWLY SOUTHWARD OVER THE NEXT 24 TO 36 HOURS. THE COMBINATION OF LIGHT SRLY FLOW AND HIGH MOISTURE CONTENT IN THE BLYR WILL LEAD TO ANOTHER VERY WARM NIGHT (AND TRENDED ABOVE GUIDANCE). THE GFS/NAM DIFFER ON CONVECTIVE/PRECIP POTENTIAL ACROSS THE REGION ON MONDAY WITH THE NAM FOCUSING THE ACTIVITY IN THE VCNTY OF THE UPPER LOW TO OUR WEST AND FRONT TO OUR NORTH. HAVE TRENDED BACK A SLIGHT BIT ON POPS...BUT OVERALL REMAIN CLOSER TO THE MORE AGGRESSIVE GFS GIVEN THE INSTABILITY (AND LACK OF CAP) THAT WILL BE IN PLACE IN THE WARM SECTOR. PRECIP POTENTIAL WILL DEFINITELY BE ON THE RISE BY TUESDAY AS A TROUGH BEGINS TO BUILD ACROSS THE NORTHEAST AND PUSHES THE SFC FRONT INTO THE TN VLY. EXPECT SCT/NMRS THUNDERSTORMS ON TUE/TUE NIGHT WHEN CONVERGENCE AND INSTABILITY WILL BE MAXIMIZED. SOME MODEST UPPER LEVEL SUPPORT (20-30 KT FLOW ALOFT) WOULD POINT TOWARD MORE STORM ORGANIZATION. PWATS WILL ALSO BE ON THE ORDER OF 2 INCHES...SO HEAVY/EFFICIENT RAIN PRODUCING STORMS SEEM LIKELY. THE UNSETTLED PERIOD WILL PERSIST INTO THE EXTENDED FORECAST TIME FRAME AS THE WRN US RIDGE/ERN US TROUGH PATTERN BECOMES ESTABLISHED. THIS WILL ALLOW THE AFOREMENTIONED FRONTAL BOUNDARY TO SETTLE IN THE VICINITY OF THE LOWER TENNESSEE VALLEY THROUGH LATE IN THE WORK WEEK. WE MAY ALSO SEE A SERIES OF WEAK...ILL DEFINED...SHORTWAVE TROUGHS ROUND THE BASE OF THE L/W TROUGH AND HELP AMPLIFY PRECIPITATION CHANCES FROM TIME TO TIME. HARD TO PIN DOWN EXACT TIMING GIVEN SOME UNCERTAINTIES IN THE ECMWF/GFS...BUT OVERALL WILL RETAIN MID RANGE POPS THROUGH MUCH OF THE EXTENDED PERIOD. TEMPERATURES WILL ALSO BE ABOUT 10 DEGREES (IF NOT A BIT MORE) COOLER THAN WE'VE SEEN OVER THE PAST TWO WEEKS DUE TO CLOUD COVER AND INCREASED RAIN POTENTIAL. 15 && .AVIATION... /ISSUED 1244 PM CDT SUN JUL 8 2012/ FOR 18Z TAFS...VFR CONDITIONS EXPECTED AT KHSV/KMSL TERMINALS OVER MOST OF THE FORECAST PERIOD. HOWEVER...THE DEVELOPMENT OF SHRA/TSRA IS EXPECTED TODAY IN NORTHERN AL. COVERAGE OF SHRA/TSRA IS EXPECTED TO BE SCATTERED IN NATURE AND TIMING OF ANY ASSOCIATED IMPACTS AT TAF SITES IS NOT POSSIBLE AT THIS POINT. SO...VCTS WAS USED TO DENOTE THE CONVECTIVE POTENTIAL IN TAFS ATTM. CORES WITHIN SHRA/TSRA ARE LIKELY TO BE HEAVY AND WOULD LIKELY RESTRICT CIGS/VIS TO IFR OR PERHAPS LOWER IF A CELL IMPACTED A SITE. WILL HAVE TO MONITOR AND AMEND TAFS IF NECESSARY. SHRA/TSRA COVERAGE IS EXPECTED TO DIMINISH OVERNIGHT...BUT SOME SHRA ACTIVITY MAY LINGER. KDW && .PRELIMINARY POINT TEMPS/POPS...
