NWS Fort Worth, TX wrote its last area forecast discussion before the first event at Aug 7, 11:28 AM CST, 1 hour 52 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE FORT WORTH TX 1228 PM CDT TUE AUG 7 2012 .AVIATION... CONCERNS...LOW THUNDERSTORM CHANCES LATE AFTERNOON/EARLY EVENING. ISOLATED SHOWERS AND THUNDERSTORMS NORTHWEST OF A K0F2 TO KBKD LINE...WILL CONTINUE TO MOVE SOUTHWEST AND NOT AFFECT THE METROPLEX TAF SITES. CUMULUS FIELDS HAVE ALREADY DEVELOPED TO THE NORTHEAST...SOUTHEAST AND SOUTHWEST OF THE METROPLEX AS OF MIDDAY. EXPECT ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS TO DEVELOP LATER THIS AFTERNOON ACROSS THE REGION. THE CHANCES IN THE METROPLEX ARE ONLY ABOUT 20 PERCENT...BUT HAVE PLACED VCTS AND CB IN THE TAF FOR THE 21-00Z PERIOD AS THESE STORMS WILL HAVE THE POTENTIAL TO PRODUCE STRONG DOWNBURST WINDS. 58 && .UPDATE... A FEW SHOWERS AND THUNDERSTORMS CONTINUE ACROSS THE FAR WESTERN COUNTIES ALONG A LINE FROM GRAHAM TO ABILENE. LIGHTNING HAS RECENTLY BEEN OBSERVED WITH ONE STORM IN YOUNG COUNTY BUT OTHERWISE...NOT MUCH PRECIPITATION APPEARS TO BE REACHING THE GROUND. ADDITIONAL ISOLATED TO SCATTERED THUNDERSTORMS ARE EXPECTED TO DEVELOP ACROSS THE REGION THIS AFTERNOON. DAMAGING DOWNBURST WINDS AND QUARTER SIZED HAIL WILL BE POSSIBLE WITH THE STRONGER STORMS. THE STORM ACTIVITY SHOULD DIMINISH IN THE EVENING HOURS. THE INHERITED FORECAST WAS ON TRACK BUT DID MAKE A FEW MINOR CHANGES TO THE AFTERNOON HIGHS. ALSO...INCREASED DEWPOINTS SOME FOR THE AFTERNOON HOURS. THIS WILL RESULT IN HEAT INDEX VALUES APPROACHING 105 DEGREES LATE THIS AFTERNOON IN SOME LOCATIONS...MAINLY ALONG AND EAST OF INTERSTATE 35. HOWEVER...THE TEMPERATURE FORECAST COULD BE AFFECTED BY AFTERNOON THUNDERSTORMS AND CLOUD COVER. 82/JLD && .PREV DISCUSSION... /ISSUED 341 AM CDT TUE AUG 7 2012/ WEAK NORTH TO NORTHWEST FLOW ALOFT WILL PREVAIL OVER NORTH TEXAS THROUGH EARLY NEXT AS UPPER LEVEL HIGH PRESSURE REMAINS ANCHORED ACROSS THE WESTERN STATES. WEAK LARGE SCALE LIFT COUPLED WITH A MODERATELY UNSTABLE ATMOSPHERE WILL RESULT IN ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS THE NEXT FEW DAYS WITH STORMS MOST LIKELY DURING THE HEAT OF THE AFTERNOON. ANY STORM THAT DEVELOPS IN THE AFTERNOON/EARLY EVENING WILL HAVE A POTENTIAL FOR DAMAGING DOWNBURST WINDS DUE TO DRY AIR BELOW THE HIGH BASED STORMS. PRECIPITATION CHANCES WILL DECREASE AS WE HEAD INTO THE WEEKEND AS DRIER AIR FILTERS IN BEHIND A COLD FRONT. THE DRY AIR SHOULD LINGER THROUGH THE WEEKEND AND INTO EARLY NEXT WEEK. TEMPERATURES THE REMAINDER OF THE WEEK WILL BE HOT WITH AFTERNOON HIGHS GENERALLY IN THE UPPER 90S TO AROUND 103. OVERNIGHT LOWS WILL RANGE FROM THE MID 70S TO NEAR 80. THE MIXING DOWN OF DRIER AIR SHOULD KEEP AFTERNOON HEAT INDEX VALUES BELOW 105. THEREFORE...WE WILL NOT ISSUE A NEW HEAT ADVISORY WITH THIS PACKAGE. TEMPERATURES WILL COOL A FEW DEGREES ON THE WEEKEND DUE TO VERY WEAK COLD AIR ADVECTION BEHIND THE EXPECTED COLD FRONT. 79 && .PRELIMINARY POINT TEMPS/POPS... DALLAS-FT.
