NWS Fort Worth, TX wrote its last area forecast discussion before the first event at Aug 12, 5:30 AM CST, 4 hours 30 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE FORT WORTH TX 630 AM CDT SUN AUG 12 2007 .AVIATION... 630 AM CDT LGT/VRB WINDS WILL BECOME ORGANIZED E/NE TODAY. DESPITE DRY ADVECTION...BL MOISTURE WILL REMAIN HIGH TODAY. FEW/SCT CU WILL DEVELOP LATE MORNING...DISSIPATING LATE IN THE DAY. MIXING DEPTH WILL PUT BASES AT 5KFT INITIALLY...LIFTING TO 6-7KFT. 25 && .PREV DISCUSSION... 339 AM CDT LARGE SUBTROPICAL HIGH WILL BE THE DOMINANT FEATURE FOR OUR WEATHER DURING THE NEXT WEEK. THE UPPER HIGH WILL INTENSIFY TODAY AND TOMORROW...WITH HIGH TEMPERATURES RISING TO NEAR 100 FOR THE ENTIRE AREA...WITH THE HOTTEST DAY EXPECTED MONDAY. ADDING INSULT TO INJURY WILL BE THE HIGH HUMIDITY...AS A POCKET OF HIGHER MOISTURE MOVING IN FROM THE EAST WILL HELP HEAT INDEX VALUES TOP OUT BETWEEN 105 AND 109 THIS AFTERNOON. SLIGHTLY DRIER AIR WILL BEGIN TO MOVE INTO THE REGION BY MONDAY...WITH HEAT INDEX VALUES A LITTLE LOWER. THERE IS SOME DEBATE ON WHETHER TO EXTEND THE HEAT ADVISORY BEYOND TODAY WITH HEAT INDICES MONDAY LIKELY TOPPING OUT BELOW THE 105 DEGREE CRITERIA. SINCE THE ACTUAL TEMPERATURE WILL BE HIGHER THAN PREVIOUS DAYS WE WILL CONTINUE THE HEAT ADVISORY FOR THE URBAN AREAS OF THE METROPLEX (WHERE OVERNIGHT LOWS WILL ONLY REACH THE UPPER 70S ONCE AGAIN TOMORROW NIGHT). DRIER AIR WILL CONTINUE TO FILTER IN FROM THE EAST INTO TUESDAY. OVERNIGHT LOWS WILL BE ALLOWED TO COOL A LITTLE MORE AND LESS OPPRESSIVE AFTERNOON HEAT INDICES ARE EXPECTED AS WELL. THE UPPER LEVEL RIDGE WILL BEGIN TO WEAKEN TUESDAY AND WEDNESDAY BEFORE IF SHIFTS OFF TO THE EAST LATE IN THE WEEK. AS A RESULT... HIGH TEMPERATURES WILL SLOWLY COOL INTO THE MID-UPPER 90S BY FRIDAY AND SATURDAY. THE MEX MOS LOOKS A LITTLE TOO AGGRESSIVE WITH THE COOLING TREND AND DID FORECAST TEMPS A COUPLE DEGREES WARMER THAN GUIDANCE BEYOND THURSDAY. MODELS CONTINUE TO SUGGEST THAT THE TROPICAL WAVE WEST OF JAMAICA WILL ENTER THE GULF OF MEXICO IN A COUPLE DAYS WITH SOME POTENTIAL FOR DEVELOPMENT. RIDGE SHOULD KEEP MOVEMENT OF THIS FEATURE GENERALLY WEST INTO MEXICO AND TOO FAR SOUTH TO AFFECT NORTH TEXAS. HOWEVER...GFS/CANADIAN DO ERODE THE WESTERN EXTENT OF THE RIDGE LATE IN THE WEEK WHICH MAY ALLOW FOR SOME RESIDUAL TROPICAL MOISTURE TO WORK INTO THE SOUTHWEST ZONES FRIDAY AND SATURDAY AND SPARK A FEW AFTERNOON SHOWERS. AT THIS POINT WILL KEEP POPS AT 10 PERCENT AND THE MENTION OF RAIN OUT OF THE WORDED FORECASTS. OTHERWISE...ATTENTION OF MUCH OF THE COUNTRY MAY SHIFT TOWARD THE TROPICS BY NEXT WEEKEND AS SEVERAL OF THE COMPUTER MODELS CONTINUE TO DEVELOP THE TROPICAL WAVE OFF AFRICA AND BRING IT WESTWARD INTO A POSITION THAT MIGHT THREATEN U.S. INTERESTS IN 10-14 DAYS.
