The episode as NWS FWD wrote it up.
July was another abnormally dry month with no local observation sites receiving more than an inch of rain. Drought conditions worsened across the Fort Worth County Warning Area (CWA) and by the end of the month all but 6 of the 46 counties were classified in severe drought (D2) or worse according to the US Drought Monitor. Half of the 46 counties, mainly located in the western and southern areas of the CWA, were classified in exceptional drought (D4). At the end of the month, burn bans were in effect for all but one county. Most of the area lakes continued to suffer and water levels continued to drop well below conservation levels, with some lakes more than 10 feet below normal values. The low lake levels caused many cities to implement water restrictions on residents. The agriculture community also continued to experience detrimental conditions. Hay production was nearly halted with most farmers only producing a small fraction of what is produced in a normal season. Hay prices were up to $90 a bale, which is almost double the normal price. Many cattle farmers had to sell their cows early because of the scarcity of grasses and hay. Corn farmers also witnessed poor corn production and had to try to grow other crops to salvage their growing season. The drought has also caused trees to suffer, with many trees dying or toppling due to weakened roots from little rainfall.

NWS Fort Worth, TX wrote its last area forecast discussion before the first event at Jul 11, 10:42 PM CST, 1 hour 18 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE FORT WORTH TX 1142 PM CDT MON JUL 11 2011 .AVIATION... /6Z TAFS/ VFR CONDITIONS EXPECTED THROUGH THE PERIOD OUTSIDE OF A FEW SCATTERED AFTERNOON THUNDERSTORMS ON TUESDAY. MOST ACTIVITY IS EXPECTED TO REMAIN AWAY FROM THE MAJOR AIRPORTS SO WILL NOT MENTION ANY PRECIP AT THIS TIME. OTHERWISE...HOT AND DRY WITH LIGHT SOUTHERLY FLOW CONTINUING. DUNN && .UPDATE... MID LEVEL DISTURBANCE THAT IS THE REMNANT OF AN OLD GULF OF MEXICO TUTT LOW LATE LAST WEEK IS CURRENTLY STILL SPINNING OVER THE NORTHERN TX PANHANDLE THIS EVENING PER SATELLITE IMAGERY. NIGHTFALL IS NEARLY UPON US AND ANY ISOLATED SHOWERS OVER FAR SOUTHERN AND WESTERN COUNTIES HAVE DISSIPATED. WE HAVE REMOVED MENTION OF ISOLATED SHOWERS OVERNIGHT. SOUTH-SOUTHEAST WINDS 10 TO 20 MPH WILL CONTINUE TO DIMINISH AFTER SUNSET AND LIKELY FALL TO OR BELOW 10 MPH OVERNIGHT UNDER MOSTLY CLEAR SKIES. TEMPERATURES HOWEVER WILL REMAIN VERY WARM WITH LOWS IN THE 70S...TO LOWER 80S IN IMMEDIATE URBAN AREAS WHERE A HEAT ADVISORY IS IN EFFECT FOR TARRANT/DALLAS COUNTIES THROUGH 9 PM WEDNESDAY EVENING. HEAT INDICES WILL BE GREATER THAN 105 DEGREES OVER PARTS OF NORTH TX TOMORROW BUT OVERNIGHT LOWS WILL FALL BELOW THE 78 DEGREE CRITERIA. WE DO EXPECT A STRONG POSSIBILITY OF THE HEAT ADVISORY EXPANDING OVER SEVERAL SURROUNDING COUNTIES IN OUR CWA...AS DEEP SOUTHERLY FLOW THROUGH 500 MB RESULTS IN LESS MIXING OF MOIST DEW POINTS. MEANWHILE...UPPER HIGH TO OUR WILL EXPAND BACK WEST THROUGH THE END OF THE WEEK RESULTING IN A CONTINUATION OF THE HOT WEATHER. 05/ && .PREV DISCUSSION... /ISSUED 346 PM CDT MON JUL 11 2011/ AS AN UPPER LEVEL LOW CONTINUES TO MOVE NORTH THROUGH THE TEXAS PANHANDLE...ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS HAVE DEVELOPED FROM YOUNG COUNTY TOWARDS LUBBOCK AND AMARILLO. IN ADDITION...A FEW VERY LIGHT SHOWERS ARE ALSO DEVELOPING ACROSS THE SOUTHEASTERN COUNTIES OF NORTH TEXAS. EXPECT ISOLATED CONVECTIVE ACTIVITY TO CONTINUE INTO THE EVENING HOURS. THE UPPER LEVEL LOW IS EXPECTED TO CONTINUE ADVANCING INTO OKLAHOMA TONIGHT AND TOMORROW AS THE UPPER LEVEL RIDGE BUILDS BACK IN FROM THE EAST. THE REMNANTS OF THIS LOW WILL CONTINUE RIDING AROUND THE NORTHERN PERIPHERY OF THE RIDGE AND THEN SLIDE SOUTH INTO THE MISSISSIPPI RIVER BASIN BY THE END OF THE WEEK. THE LATEST RUN OF THE GFS NEARLY DISSOLVES THE REMNANTS OVER THE SOUTHEASTERN CONUS AND HOLDS THE RIDGE OVER THE SOUTHERN PLAINS THROUGH THE WEEKEND. THE GFS THEN SLIDES THE RIDGE TO THE NORTHWEST NEXT WEEK AND BRINGS A FEW OTHER WEAK DISTURBANCES ACROSS THE REGION. THE CANADIAN MODEL IS ADVERTISING A SIMILAR PATTERN. HOWEVER...THE ECMWF CONTINUES TO BRING THE REMNANTS OF THE LOW BACK ACROSS NORTH TEXAS /ON THE SOUTH SIDE OF THE RIDGE/ THIS WEEKEND. THEN IT ALSO SLIDES THE RIDGE TO THE NORTHWEST NEXT WEEK. THE DIFFERENCES IN THESE SCENARIOS COULD RESULT IN VARIOUS RAIN CHANCES FOR NORTH TEXAS...BUT OVERALL THE RAIN CHANCES REMAIN LOW. FOR POPS THIS WEEK...REMOVED THE MENTION OF ISOLATED THUNDER FROM THE EAST FOR TOMORROW AS THE RIDGE BUILDS BACK IN AND KEPT ISOLATED THUNDER OVER THE EAST ON WEDNESDAY. HOWEVER...KEPT 20 POPS ACROSS MUCH OF THE REGION THIS WEEKEND AND INTO NEXT WEEK...BUT THIS WILL LIKELY NEED TO BE ADJUSTED AS THE MODELS CONTINUE TO ADJUST OVER THE NEXT SEVERAL DAYS. WITH THE UPPER LEVEL RIDGE BUILDING BACK OVER THE REGION BEGINNING TOMORROW...TEMPERATURES WILL INCREASE SLIGHTLY. A HEAT ADVISORY IS BEING ISSUED FOR DALLAS AND TARRANT COUNTIES AT THIS TIME FOR TONIGHT THROUGH WEDNESDAY. THE REST OF NORTH TEXAS WILL ALSO BE HOT DURING THIS TIME PERIOD...BUT EITHER OVERNIGHT LOWS ARE FORECAST TO BE BELOW ADVISORY CRITERIA OR LOWER HEAT INDEX VALUES ARE FORECAST IN THE AFTERNOON DUE TO LOWER DEWPOINT MIXING IN THE REMAINING COUNTIES. HOWEVER...ADDITIONAL HEAT ADVISORIES FOR LARGER AREAS OF NORTH TEXAS MAY BE REQUIRED LATER THIS WEEK. 82/JLD && .PRELIMINARY POINT TEMPS/POPS... DALLAS-FT.
