The episode as NWS FWD wrote it up.
Scattered to numerous thunderstorms developed in an unstable environment aided by diffluence aloft and differential heating. Most of the thunderstorms occurred along a line from Stephenville to Dallas to Cooper. A few of the thunderstorms produced damaging winds that caused minor damage but did tear the roof off one business in Johnson County.

NWS Fort Worth, TX wrote its last area forecast discussion before the first event at Aug 16, 11:47 AM CST, 2 hours 38 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE FORT WORTH TX 1247 PM CDT SAT AUG 16 2014 .AVIATION... /18Z TAFS/ VFR CONDITIONS EXPECTED THROUGH MOST OF THE PERIOD OUTSIDE OF AREAS OF CONVECTION THIS AFTERNOON AND EVENING. WATER VAPOR IMAGERY SHOWS A DISTURBANCE OVER WEST TEXAS MOVING IN THIS DIRECTION AND SHOULD PROVIDE SOME FORCING FOR ASCENT THROUGH THE AFTERNOON. A BAND OF CUMULUS CLOUDS HAVE DEVELOPED FROM NEAR STEPHENVILLE NORTHEAST INTO THE METROPLEX AND THIS IS EXPECTED TO BE THE FAVORED AREA FOR THUNDERSTORM DEVELOPMENT THROUGH EARLY EVENING. THE ATMOSPHERE IS FAVORABLE FOR STRONG DOWNBURST WINDS WITH ANY THUNDERSTORMS THAT DEVELOP ACROSS THE REGION THIS AFTERNOON. FOR THE 18Z TAFS...WILL STILL MAINTAIN A VCTS FROM 21Z IN THE METROPLEX AND REFINE AS STORMS DEVELOP. THIS INITIAL ACTIVITY SHOULD DIMINISH IN INTENSITY AFTER DARK. ADDITIONAL ELEVATED SHOWERS AND POSSIBLY A THUNDERSTORM MAY DEVELOP LATE TONIGHT. OTHERWISE...VFR CONDITIONS WILL PREVAIL WITH GENERALLY SOUTHERLY WINDS. DUNN && .UPDATE... BAND OF LINGERING ELEVATED SHOWERS IS ON THE WESTERN EDGE OF THE CWA AND WILL CONTINUE TO MOVE SLOWLY EAST BEFORE DISSIPATING ALTOGETHER BY EARLY AFTERNOON. CLOUD COVER ASSOCIATED WITH THIS ACTIVITY NECESSITATES LOWERING HIGH TEMPS IN THE NORTHWESTERN ZONES. OTHERWISE DIFFERENTIAL HEATING BETWEEN THIS AREA AND LOCATIONS JUST TO THE EAST WILL LIKELY PROMOTE A REGION OF ENHANCED LOW LEVEL CONVERGENCE AND WILL BECOME THE FAVORED AREA FOR AFTERNOON CONVECTION TO INITIATE. THROUGH 7 PM...WILL SHOW HIGHEST POPS OF 30 PERCENT IN A BAND FROM COMANCHE TO MINERAL WELLS TO SHERMAN. AFTERNOON ACTIVITY WILL HAVE THE POTENTIAL TO PRODUCE DAMAGING WINDS. TR.92 && .PREV DISCUSSION... /ISSUED 359 AM CDT SAT AUG 16 2014/ A CHALLENGING CONVECTIVE FORECAST LIES AHEAD THROUGH THIS WEEKEND AND INTO EARLY NEXT WEEK. AN UPPER HIGH WAS ANCHORED OVER THE DESERT SOUTHWEST STATES WHILE AN UPPER TROUGH WAS IN CONTROL FROM THE MISSISSIPPI VALLEY TO THE MID ATLANTIC STATES. THIS HAS PLACED OUR AREA UNDERNEATH WEAK NORTHWEST FLOW ALOFT. IN ADDITION... A TUTT /TROPICAL UPPER TROPOSPHERIC TROUGH/ FEATURE WAS OVER THE WESTERN GULF OF MEXICO AND BAY OF CAMPECHE. AN AREA OF DECAYING CONVECTION WAS NOTED OVER WEST AND NORTHWEST TEXAS WITH A RESIDUAL OUTFLOW BOUNDARY/GRAVITY WAVE MOVING THROUGH OUR FAR NORTHWEST COUNTIES. THE OUTFLOW BOUNDARY FROM THIS MORNING/S WEST TEXAS ACTIVITY IS EXPECTED TO BE THE KEY SURFACE FEATURE THIS AFTERNOON AND EVENING AS IT SETTLES ACROSS OUR NORTHWEST COUNTIES. ISOLATED TO SCATTERED STORM ARE EXPECTED TO DEVELOP OFF THIS FEATURE BY THIS AFTERNOON WITH A SHORTWAVE APPROACHING THE AREA. WINDS ALOFT OVER NORTH AND CENTRAL TEXAS WILL BE WEAK WITH A DIFFLUENT REGIME OVER THE AREA BETWEEN THE THREE SYNOPTIC FEATURES NOTED ABOVE. HOT TEMPERATURES BETWEEN 97 AND 103 DEGREES WILL OCCUR BY THIS AFTERNOON ELIMINATING ANY WEAK INHIBITION. MID LEVEL MOISTURE ABOVE 10 KFT WILL BE ON THE INCREASE...WHILE THE STRONG DAYTIME INSOLATION AND DEEP MIXING WILL RESULT IN LOWER LEVEL INVERTED-V TYPE PROFILES. DESPITE THE DRY LOW LEVEL ENVIRONMENT...INSTABILITY IN SPOTS WILL INCREASE TO BETWEEN 1000-2000 J/KG OF SBCAPE WITH HIGH PWATS BETWEEN 1.75 AND 2 INCHES IN PLACE DUE TO THE HIGHER LEVEL MOISTURE. THE EXPECTED THERMODYNAMIC ENVIRONMENT IS EXPECTED TO BE CONDUCIVE FOR STRONG TO SEVERE WET MICROBURSTS EACH AFTERNOON THROUGH TUESDAY. SUMMERTIME MICROBURSTS ARE A RESULT OF COLLAPSING STORMS WHICH PRODUCE RAPIDLY DESCENDING COLUMNS OF RAIN-COOLED AIR TOWARD THE GROUND. WINDEX...A PARAMETER USED TO MEASURE POTENTIAL DOWNBURST STRENGTH FROM THE MELTING LEVEL TO THE SURFACE INDICATES 65-75 MPH WILL BE POSSIBLE ALONG AND AHEAD OF THIS MORNING/S OUTFLOW BOUNDARY. WE HAVE SKEWED TODAY/S CONVECTIVE CHANCES MORE TOWARD THE NORTHWEST COUNTIES... THEN BRING THOSE SLIGHTLY HIGHER CHANCES ACROSS AREAS ALONG INTERSTATE 20 AND POINTS NORTH TONIGHT. WE DID NOT EXCEED 30 PERCENT ON CHANCES WITH THE LOCALIZED NATURE OF STORMS AND UNCERTAINTIES REGARDING WHERE BOUNDARIES SET UP FOR STORM INITIATION. PERSONS INVOLVED IN OUTDOOR RECREATIONAL ACTIVITIES THIS AFTERNOON AND EVENING WILL NEED TO KEEP AN EYE TO THE SKY AS STORMS CAN RAPIDLY DEVELOP AND SUBSEQUENTLY RAPIDLY COLLAPSE. A SIMILAR UPPER LEVEL PATTERN WILL REMAIN IN PLACE THROUGH THE EARLY PART OF THE WEEK AS SHORTWAVE ENERGY WITHIN THE NORTHWEST FLOW ALOFT TRANSVERSES OVER THE AREA. WE WILL KEEP LOW CONVECTIVE CHANCES THROUGH THE NIGHTTIME HOURS WITH MID LEVEL ENERGY AROUND...THOUGH DIMINISHING INSTABILITY SHOULD RESULT IN A DROP OFF IN INTENSITY AND COVERAGE. POSITION OF OLD STORM BOUNDARIES ARE MUCH TOO DIFFICULT TO PINPOINT BEYOND 24 HOURS WHICH MAKES DETERMINING WHERE HIGHER CHANCES FOR RAIN WILL OCCUR NEAR IMPOSSIBLE. WE HAVE DECIDED TO LEAVE THE PRECIPITATION FORECAST RELATIVELY UNCHANGED...BUT DID EXPAND SLIGHT CHANCES INTO OUR FAR SOUTHEAST COUNTIES FROM SUNDAY AFTERNOON THROUGH MONDAY NIGHT. THOUGH HIGH TEMPERATURES WILL BE SLIGHTLY LOWER DUE TO MORE CLOUD COVER...THE THERMODYNAMIC ENVIRONMENT WILL REMAIN CONDUCIVE FOR MICROBURSTS DURING THE AFTERNOON INTO THE EARLY EVENING HOURS. WE WILL HAVE TO ADJUST POPS LIKELY ON A DAY TO DAY BASIS THE NEXT SEVERAL DAYS DEPENDING ON WHERE SURFACE BOUNDARIES SET UP. IT WILL CONTINUE TO BE HOT WITH HEAT INDICES REACHING OR BRIEFLY EXCEEDING 105 DEGREES ACROSS THE EASTERN HALF OF THE CWA TODAY. HOWEVER...WITH HIGH TEMPERATURES NOT QUITE AS HOT SUNDAY INTO MONDAY...HEAT INDICES WILL BE LOWER AND THUS THE TWO-DAY CRITERIA FOR A HEAT ADVISORY WILL NOT BE MET. .EXTENDED FORECAST... THE EASTERN CONUS UPPER TROUGH WILL DAMPEN BY MID WEEK WHILE THE UPPER HIGH SLIDES BACK TO THE EAST ACROSS THE SOUTHEAST U.S. IN RESPONSE TO AN UPPER TROUGH SETTING UP OVER THE WESTERN U.S. COAST. NORTH TEXAS WILL BE ON THE PERIPHERY OF THE SOUTHEAST U.S. HIGH WITH UNCERTAINTY REGARDING HOW STRONG SUBSIDENCE WILL BE OVER THE AREA. REGARDLESS... LOOK FOR HOT CONDITIONS TO CONTINUE WITH A FEW AREAS EXCEEDING THE CENTURY MARK ONCE AGAIN THROUGH NEXT WEEKEND. DIURNAL SEABREEZE BOUNDARIES AND LOW RAIN CHANCES FOR OUR SOUTHEAST COUNTIES EACH DAY MAY OCCUR DEPENDING ON THE POSITION OF THE SOUTHEAST U.S. UPPER HIGH. FOR NOW WE WILL KEEP THE FORECAST DRY AS CONFIDENCE REMAINS LOW ON THE OCCURRENCE OF ANY SEABREEZE BOUNDARIES MAKING IT THIS FAR NORTH. 05/ && .PRELIMINARY POINT TEMPS/POPS... DALLAS-FT.
