NWS Fort Worth, TX wrote its last area forecast discussion before the first event at Aug 13, 10:35 PM CST, 1 hour 25 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE FORT WORTH TX 1135 PM CDT MON AUG 13 2012 .AVIATION... QUIET WEATHER WILL PERSIST FOR THE NEXT 18 HOURS WITH MOSTLY CLEAR SKIES AND LIGHT EAST/SOUTHEAST WINDS. A DISTURBANCE WILL ENTER NORTH TEXAS FROM THE NORTHWEST LATE TOMORROW AFTERNOON AND EVENING AND SHOULD ALLOW FOR ISOLATED TO SCATTERED STORMS TO DEVELOP. THESE COULD AFFECT THE METRO SITES BUT WILL NOT MENTION ANYTHING AT THIS TIME...DUE TO LOW PROBABILITIES. FUTURE SHIFTS MAY NEED TO ADD THUNDER IF PROBABILITIES INCREASE. 85/NH && .PREV DISCUSSION... /ISSUED 358 PM CDT MON AUG 13 2012/ FRONTAL BOUNDARY WHICH HAS SLOWLY PROGRESSED SOUTHWARD THROUGH THE DAY HAS NOW BECOME ABOUT STATIONARY ACROSS THE SOUTHERN HALF OF THE CWA. IT IS NOTED FAIRLY WELL ON VISIBLE SATELLITE WHERE A CU FIELD HAS DEVELOPED FROM NEAR ATHENS TO WACO TO LAMPASAS. MORE SIGNIFICANT HOWEVER IS THE SUBSTANTIALLY DRIER AIR LOCATED TO THE NORTH. DEWPOINTS HAVE DROPPED INTO THE LOWER 40S IN MANY AREAS AND DESPITE THE TEMPS CLIMBING INTO THE LOW 100S...THE AIR DOESNT FEEL THAT UNCOMFORTABLE. ON THE CONTRARY...SOUTH OF THE FRONT IT IS QUITE UNPLEASANT WITH TEMP/HUMIDITY APPROACHING HEAT ADVISORY CRITERIA. HIGH RES MODEL GUIDANCE INDICATES THAT THE FRONTAL BOUNDARY WILL CONTINUE TO SERVE AS A FOCUS FOR ISOLATED THUNDERSTORM DEVELOPMENT THROUGH EVENING. ONLY A FEW SPOTTY SHOWERS HAVE BEEN OBSERVED SO FAR AND THINK BULK OF ANY ACTIVITY WILL REMAIN SOUTH OF THE CWA. WILL RETAIN SOME 20 POPS THROUGH 00Z. ANY STORMS THAT DEVELOP WILL CONTINUE TO POSE A DOWNBURST WIND THREAT...ALTHOUGH THAT THREAT WILL NOT BE AS SUBSTANTIAL AS YESTERDAY. WITH CLEAR SKIES TO THE NORTH AND VERY DRY AIR IN PLACE...TEMPS SHOULD FALL NICELY AFTER SUNSET TONIGHT. AREAS NORTH OF THE FRONT WILL LIKELY DROP INTO THE UPPER 60S AND LOWER 70S...WHILE SOUTH OF THE BOUNDARY WHERE MOISTURE CONTENT IS HIGHER...LOWS WILL BE IN THE MID/UPPER 70S. SOME CHANGES ARE IN STORE FOR NORTH TEXAS WEATHER HEADED THROUGH THE UPCOMING WEEK INTO THE WEEKEND. A GENERAL NORTHWEST FLOW ALOFT WILL PREVAIL THROUGH THE REMAINDER OF THE WEEK WHICH WILL PROVIDE SOME SUPPORT FOR THUNDERSTORM DEVELOPMENT OVER THE NEXT SEVERAL DAYS. TOMORROW AFTERNOON AND EVENING AS THE OLD FRONTAL BOUNDARY RETREATS NORTHWARD...THUNDERSTORMS ARE EXPECTED TO DEVELOP IN WEAK UPSLOPE FLOW ACROSS THE TX PANHANDLE AND WESTERN OKLAHOMA. THESE WILL GENERALLY MOVE EAST SOUTHEAST. THE MID-UPPER LEVEL FLOW IS NOT OVERLY STRONG SO ANY CLUSTER OR COMPLEX THAT DEVELOP SHOULD BE DRIVEN BY SURGING OUTFLOW. INSTABILITY WILL BE STRONGEST DURING THE EARLY EVENING HOURS AND WILL BEGIN TO WANE DURING THE OVERNIGHT HOURS WHICH SHOULD ALLOW THE SYSTEM TO WEAKEN. HIGH RESOLUTION GUIDANCE APPEARS TO HAVE A HANDLE ON THIS...DRIVING THE SYSTEM SOUTHEAST WHILE WEAKENING IT AT THE SAME TIME. WILL CONTINUE WITH SOME 20/30 POPS MAINLY ACROSS THE NORTHERN HALF OF THE CWA. ON WEDNESDAY...LOW LEVEL FLOW STRENGTHENS AS A STRONGER TROUGH DIVES INTO THE UPPER PLAINS. EXPECT WEDNESDAY TO BE A BIT BREEZY ALTHOUGH PRECIPITATION CHANCES APPEAR RATHER LOW AT THIS TIME. MORE SIGNIFICANT CHANGES BEGIN STARTING THURSDAY WITH THE MEDIUM RANGE GUIDANCE SHOWING THIS STRONG TROUGH DIGGING INTO THE EASTERN US. THE GUIDANCE HAS BEEN FAIRLY CONSISTENT WITH THIS FEATURE OVER THE LAST SEVERAL DAYS AND CONFIDENCE IS INCREASING IN THE LATE WEEK FORECAST. A 1022MB SURFACE HIGH BUILDS INTO THE CENTRAL US WITH A RATHER STRONG COLD FRONT MOVING TOWARD NORTH TEXAS BY FRIDAY. THIS PATTERN...WHILE NOT COMPLETELY UNCOMMON FOR THIS TIME OF YEAR...WILL BRING A NICE BREAK FROM THE HOT WEATHER TO OUR AREA. WITH THE FRONTAL BOUNDARY STALLED AND DRAPED ACROSS NORTH TEXAS...INCREASING UPPER LEVEL NORTHERLY FLOW AND SOME INSTABILITY... IT APPEARS THAT WE WILL SEE SEVERAL DAYS OF AT LEAST SCATTERED SHOWERS AND THUNDERSTORMS...ALONG WITH COOLER TEMPERATURES. WILL HAVE HIGHEST POPS ACROSS NORTH TEXAS ON FRI/SAT AND HAVE EXTENDED SCATTERED THUNDERSTORM CHANCES INTO SUNDAY. WITH MORE SUBSTANTIAL CLOUD COVER AND SCATTERED THUNDERSTORMS ALONG WITH SIGNIFICANTLY COOLER TEMPERATURES FROM 850-500MB...SURFACE HIGHS ARE EXPECTED TO ONLY BE IN THE LOW 90S THROUGH THE UPCOMING WEEKEND.
