The episode as NWS SHV wrote it up.
Deep tropical moisture associated with the remnants of Tropical Storm Bonnie spread into northeast Texas, northern Louisiana, southwest Arkansas and southeast Oklahoma. The moisture combined with very warm afternoon temperatures to produce a very unstable environment across the region. The result was scattered to numerous showers and thunderstorms...some of which produced damaging wind gusts, and locally heavy rainfall amounts.
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 Shreveport, LA wrote its last area forecast discussion before the first event at Jul 27, 2:22 PM CST, 2 hours 48 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SHREVEPORT LA 322 PM CDT TUE JUL 27 2010 .DISCUSSION... NOT MUCH HAS CHANGED IN THE WEATHER PATTERN SINCE YESTERDAY. A SLOW WESTWARD MOVING UPPER LOW IS STILL OVER NORTH TEXAS WITH A RIDGE OVER THE SOUTHEAST U.S. THIS COMBINATION WAS BRINGING SOUTHERLY FLOW AT ALL LEVELS WHICH HAS RESULTED IN PW VALUES OVER 2 INCHES. COMBINED WITH DAYTIME HEATING...SHOWERS AND THUNDERSTORMS HAVE INCREASED IN COVERAGE...AND WILL CONTINUE WELL INTO THE EVENING. NOT EXPECTING A LOT OF CHANGE GOING INTO WEDNESDAY...EXCEPT THE UPPER RIDGE WILL BEGIN TO BUILD WEST...AND THIS MAY RESULT IN A LITTLE LESS CONVECTION. BY THURSDAY...MODEL CONSENSUS HAS THE RIDGE OVER SOUTHCENTRAL OKLAHOMA. NAM AND ECF SLIGHTLY WEAKER WITH THE STRENGTH...BUT IN ANY CASE THE POSITION WILL CHANGE UPPER WINDS TO THE NORTH...AND PW VALUES SHOULD DROP. CONVECTION SHOULD BECOME ISOLATED IF ANY AT ALL. THE RIDGE WILL BUILD THROUGH THE WEEKEND...AND THIS SHOULD DRY OUT WET SOILS...ALLOWING TEMPERATURES TO WARM TO NEAR 100 OVER MUCH OF THE REGION. WITH SOUTHERLY FLOW STILL EXPECTED IN THE LOWER LEVELS...DEWPOINTS WILL STILL REMAIN HIGH...SO HEAT ADVISORIES LOOK POSSIBLE BY THIS WEEKEND...IF NOT SOONER. RIDGE SHIFTS TO THE MIDSOUTH BY MONDAY PER GFS...AND THIS POSITION MAY ALLOW FOR WIDELY SCATTERED DIURNAL CONVECTION TO RESTART GOING INTO EARLY NEXT WEEK. HOWEVER...ECM KEEPS IT CENTERED TO THE WEST OF THE CWA...THUS NORTHERLY WINDS CONTINUE ALOFT...KEEPING ANY SEA BREEZE CONVECTION AWAY FROM THE CWA. WILL FOLLOW THE GFS FOR NOW. .AVIATION...
