NWS Fort Worth, TX wrote its last area forecast discussion before the first event at Jul 8, 11:40 AM CST, 1 hour 30 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE FORT WORTH TX 1240 PM CDT THU JUL 8 2010 .AVIATION... THE PRIMARY AVIATION WEATHER CONCERN TODAY WILL BE THE PLACEMENT AND TIMING OF THUNDERSTORMS. THE BEST LIFT THIS AFTERNOON WILL REMAIN TO THE NORTH/NORTHWEST OF THE METROPLEX TAF SITES...NEAR A WEAK COLD FRONT. HOWEVER...NUMEROUS SMALL SHOWERS AND THUNDERSTORMS WILL DEVELOP AND MOVE NORTHWARD ACROSS THE REGION AS DEEP TROPICAL MOISTURE STREAMS NORTHWARD. THE MOST LIKELY WINDOW THAT THIS ACTIVITY WILL IMPACT THE TAF SITES WILL BE BETWEEN 18Z AND 22Z. SHOWERS AND ISOLATED THUNDERSTORMS WILL BE POSSIBLE OVERNIGHT BUT COVERAGE SHOULD BE MORE CONFINED TO SOUTH TEXAS AND ALONG THE FRONT. SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE AGAIN ON FRIDAY AS THE FRONT SAGS SOUTHWARD. FOR NOW WILL JUST INCLUDE VCSH FROM 16Z. SOME MVFR CEILINGS WILL RETURN TO ALL TAF SITES EARLY FRIDAY MORNING BUT CEILINGS SHOULD LIFT BY 16Z. 79 && .UPDATE... WILL LEAVE THE CURRENT FLASH FLOOD WATCH AS IS...BUT ILL BE TRIMMING FOR THE AFTERNOON PACKAGE. RADARS HAVE LITE UP DURING THE MORNING WITH AN AREA OF DIMINISHED ACTIVITY OVER THE EAST CENTRAL COUNTIES WHERE UPPER RIDGING EXISTS. A CONTINUOUS FETCH OF TROPICAL MOISTURE FROM TD #2 WILL PERSIST INTO FRIDAY...THUS WE/LL KEEP POPS HIGHER THROUGH TONIGHT THEN BEGIN TO BACK OFF OVER THE SOUTHERN AREAS. A WEAK DIFFUSED FRONT WILL MOVE INTO OR JUST SOUTH OF THE RED RIVER VALLEY TONIGHT AND BE THE FOCUS FOR MORE HEAVY RAINFALL ON FRIDAY. LITTLE CHANGE IN PREVIOUS FORECAST PACKAGE... BUT DID ADJUST POPS DOWN SLIGHTLY OVER THE FAR EAST THIS AFTERNOON AND EVENING. 75 && .PREV DISCUSSION... /ISSUED 329 AM CDT THU JUL 8 2010/ THREAT FOR HEAVY RAINFALL WILL BE GREATEST TODAY AS TROPICAL MOISTURE FROM TD #2 OVER THE WESTERN GULF OF MEXICO STREAMS INTO TEXAS...BUT IT APPEARS THAT THE HIGHEST CHANCE FOR RAINFALL WILL BE OVER OUR SOUTHERN AND SOUTHWESTERN COUNTIES TODAY...INTO CENTRAL AND SOUTHERN TEXAS. FORECAST QPF AMOUNTS OVER OUR EASTERN ROW OR TWO OF COUNTIES HAVE DECREASED TO AROUND AN INCH OR LESS AND DEBATED REMOVING THESE COUNTIES FROM THE WATCH BUT AFTER COLLABORATION WITH SURROUNDING OFFICES AND CONSIDERING THE SATURATED SOILS...WILL LEAVE FLASH FLOOD WATCH IN EFFECT FOR ALL OF NORTH TEXAS AND THE NEXT SHIFTS CAN TRIM COUNTIES TODAY IF NEEDED. HOWEVER...WITH THE UPPER LEVEL RIDGE ALREADY BEGINNING TO EXTEND INTO EAST TEXAS...THINK THE PRECIPITATION WILL BE MORE SCATTERED IN NATURE OVER OUR EASTERN ZONES BUT HEAVY RAINFALL FROM ANY SHOWER OR THUNDERSTORM WILL STILL BE POSSIBLE. THE UPPER LEVEL RIDGE WILL BUILD ACROSS NORTH TEXAS TONIGHT AND CENTER OVER THE STATE ON FRIDAY. A WEAK COLD FRONT TO OUR NORTHWEST WILL BECOME THE FOCUS FOR RAIN DEVELOPMENT ON FRIDAY BUT WEAK FLOW WITHIN THE ATMOSPHERE SUGGESTS THAT THE ACTIVITY MAY BE MORE SCATTERED. RICH TROPICAL MOISTURE WILL STILL BE IN PLACE ON FRIDAY BUT THE FORCING ALONG THE FRONT IS NOT VERY STRONG AND WIDESPREAD RAINFALL MAY NOT OCCUR. HAVE TRIMMED POPS SOME FOR FRIDAY AND THE FLASH FLOOD WATCH MAY HAVE TO BE ADJUSTED IN AREAL COVERAGE AND TIME IF SUCCESSIVE MODEL RUNS CONTINUE TO SUGGEST WEAK FORCING ALONG THE FRONT. WILL CONTINUE WITH 20 TO 30 POPS ACROSS THE REGION ON SATURDAY WITH THE FRONT STILL LYING TO OUR NORTH AND DIURNAL CONVECTION POSSIBLE. THE UPPER LEVEL RIDGE BEGINS TO BE PUSHED SOUTH ON SUNDAY AS AN UPPER LEVEL TROUGH TAKES SHAPE OVER THE WESTERN CONUS AND HAVE INTRODUCED POPS ACROSS THE NORTHERN HALF ON SUNDAY. RAIN CHANCES WILL CONTINUE THROUGH TUESDAY AS THE UPPER LEVEL TROUGH MOVES THROUGH THE PLAINS. MOVING INTO THE LATTER HALF OF NEXT WEEK...THE GFS BUILDS THE RIDGE BACK OVER THE SOUTHERN PLAINS WHILE THE ECMWF IS NOW DEVELOPING A SECOND TROUGH TO AFFECT THE REGION. FOR NOW WILL KEEP A DRY FORECAST BEYOND TUESDAY. TODAY WILL BE THE COOLEST DAY OF THE WEEK AND THEN TEMPERATURES WILL STEADILY WARM THIS WEEKEND. OVERNIGHT LOWS WILL ALSO BE ON THE RISE WITH THE PRESENCE OF THE UPPER LEVEL RIDGE AND SOUTHWEST FLOW IN THE LOWER LEVELS OF THE ATMOSPHERE. 82/JLD && .PRELIMINARY POINT TEMPS/POPS... DALLAS-FT.
