NWS Fort Worth, TX wrote its last area forecast discussion before the first event at Aug 29, 6:09 AM CST, 1 hour 36 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE FORT WORTH TX 709 AM CDT MON AUG 29 2011 .UPDATE... BANDING OF SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS NOW OCCURRING A LITTLE FURTHER WEST WITH WEAK FORCING OF A SHORTWAVE DISTURBANCE ACROSS WESTERN OKLAHOMA. THIS BAND OF SHOWERS AND THUNDERSTORMS WAS MOVING DUE SOUTH AND HAVE RAISED POPS ACROSS THE EASTERN HALF OF NORTH TEXAS...ESPECIALLY NE COUNTIES. ANY RAINFALL NO MATTER HOW SCATTERED IS A WELCOME SITE FOR NORTH TEXAS WITH THE ONGOING DROUGHT. WE HAVE ALSO LOWERED HIGHS TODAY SLIGHTLY...MOSTLY IN THE EAST HALF WITH CLOUDS/SHOWERS MOST OF THE MORNING. IT WILL STILL BE HOT THIS AFTERNOON...BUT PROBABLY A FEW DEGREES COOLER DEPENDING ON HOW MUCH THE CLOUD COVER BREAKS OUT THIS AFTERNOON. EXPECT MORE OF A FOCUS ACROSS WESTERN NORTH TEXAS LATER DAY WITH OUTFLOW BOUNDARIES AND SHOWERS STABILIZING THE EAST AND ALLOWING FOR SOME DIFFERENTIAL HEATING WEST OF I-35 E/W. 05/ && .AVIATION... A BAND OF SHOWERS AND ISOLATED STORMS EXTENDS FROM A LARGE CONVECTIVE COMPLEX NEAR THE OK/AR BORDER SOUTHWESTWARD INTO NORTH TEXAS. LIFT FROM SOUTHWESTWARD EXTENT OF SHORTWAVE HAS BEEN SUFFICIENT ENOUGH TO PRODUCE SOME LIGHT SHOWERS DURING THE PAST COUPLE OF HOURS NEAR THE DALLAS-FORT WORTH AREA. LOOKS LIKE POTENTIAL IS DECREASING SOMEWHAT AS INITIAL ENERGY SHIFTS EAST OF THE REGION. HOWEVER...REDEVELOPMENT IS OCCURRING ALONG AND NORTH OF THE RED RIVER ON BACK EDGE OF MAIN COMPLEX...AND FEEL SOME OF THIS ACTIVITY MAY BUILD SOUTH TOWARDS DFW TRACON DURING THE NEXT FEW HOURS AND WILL INCLUDE A CB IN MORNING PORTION OF METRO-AREA TAFS. LOOKS LIKE WINDS WILL THEN PICK UP OUT OF THE SOUTH IN THE 10-15 KT RANGE LATE THIS MORNING AND THIS AFTERNOON. AT THIS TIME BELIEVE THUNDER WILL BE TOO ISOLATED TO INCLUDE IN AFTERNOON PORTION OF FORECASTS...BUT AS ALWAYS WILL MONITOR LATER TRENDS AND UPDATED SHORT TERM GUIDANCE FOR FUTURE ISSUANCES. OTHERWISE WILL CONTINUE WITH VFR CONDITIONS FOR THE REST OF THE FORECAST PERIOD WITH ONLY MID LEVEL CLOUDS EXPECTED. 30 && .PREV DISCUSSION... /ISSUED 335 AM CDT MON AUG 29 2011/ MINOR CHANGES TO THE FORECAST EARLY THIS MORNING WITH RESPECT TO RAIN CHANCES. WEAK LOW PRESSURE NEAR WICHITA FALLS SHIFTS NORTHEAST INTO SOUTHERN OKLAHOMA TODAY...WEAKENING OR STALLING AN OLD STORM OUTFLOW BOUNDARY IN THE VICINITY OF THE RED RIVER VALLEY. MEANWHILE A WEAK SHORTWAVE DISTURBANCE WILL ROTATE SOUTH TOWARD NORTH TEXAS THROUGH THE DAY WITH MORE MOISTURE-RICH AIRMASS SINKING SOUTH ACROSS THE RED RIVER VALLEY ALONG THE EASTERN PERIPHERY OF THE UPPER HIGH CENTERED OVER AZ/NM. RADAR AND SATELLITE CONTINUE TO INDICATE WIDELY SCATTERED SHOWERS AND THUNDERSTORMS MOVING SOUTH ALONG THE ELEVATED INSTABILITY AXIS FROM EASTERN OK/WESTERN AR INTO THE ARKLATEX REGION. WE HAVE ADDED LOW CHANCES FOR SHOWERS AND THUNDERSTORMS ACROSS MOST OF NORTHERN NORTH TEXAS THIS MORNING. THIS WILL BE MORE GARDEN VARIETY TYPE OF CONVECTION WITH SEVERE WEATHER NOT EXPECTED. BY AFTERNOON...EASTERN COUNTIES SHOULD BE MORE STABILIZED BY CLOUD COVER AND POSSIBLE OUTFLOW WHILE WESTERN COUNTIES WILL REMAIN MORE UNSTABLE AND THE FOCUS FOR A FEW SHOWERS AND THUNDERSTORMS THIS AFTERNOON AND EVENING. THE VERY HOT TEMPERATURES WILL MAKE AN ENVIRONMENT FOR LOCALLY GUSTY WINDS WITH ANY COLLAPSING STORMS. WE HAVE TONED HIGHS DOWN A FEW DEGREES THIS AFTERNOON DUE TO MORE EXPECTED CLOUDINESS THIS MORNING AND PARTLY SUNNY CONDITIONS THIS AFTERNOON. IT WILL REMAIN VERY HOT HOWEVER AND WE WILL CONTINUE CURRENT HEAT ADVISORY THROUGH EARLY THIS EVENING FOR URBAN AREAS OF THE D/FW METRO AND WACO PER OVERNIGHT LOW TEMPERATURES. THE UPPER HIGH EXPANDS BACK EAST AND OVER NORTH TEXAS TUES/WED AND NORTH TEXAS WILL CONTINUE TO EXPERIENCE HOT CONDITIONS THROUGH MID WEEK. MEDIUM RANGE MODELS STILL INDICATING A PATTERN SHIFT THE LATTER HALF OF THE WORK WEEK WITH A TUTT LOW ARRIVING THURSDAY FROM THE SOUTH AND WEAKENING THE UPPER HIGHS GRIP ON THE AREA SOMEWHAT. THIS WEAK DISTURBANCE WILL INCREASE MOISTURE OVER NORTH TEXAS AND ACT AS WEAK LIFTING MECHANISM FOR ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS LATE THURSDAY INTO THE EARLY HALF OF LABOR DAY WEEKEND. THE AFTERNOON AND EVENING HOURS SHOULD BE THE MOST ACTIVE PERIODS FOR CONVECTION. INCREASED CLOUD COVER WILL HELP KEEP HIGH TEMPERATURES RELATIVELY COOLER WITH MID TO UPPER 90S BY FRIDAY...WHICH IS A WELCOME RELIEF FROM THE RECORD HEAT SEEN LATELY. THIS WILL LIKELY NOT BREAK THE DROUGHT ACROSS THE AREA BUT COULD AT LEAST EASE CONCERNS FOR A FEW DAYS WITH ANY RAINFALL BENEFICIAL TO THE REGION. THE TUTT UPPER LOW WILL BEGIN LIFTING NORTHEAST TOWARD THE OZARKS AND MISSISSIPPI VALLEY BY LABOR DAY WITH BETTER RAIN CHANCES SHIFTING TO THE EAST. THIS WILL ALLOW THE UPPER HIGH TO EXPAND BACK EAST AGAIN...BUT NOT AS STRONG AND WITH TEMPERATURES NOT EXPECTED TO BE QUITE AS HOT. 05/ && .PRELIMINARY POINT TEMPS/POPS... DALLAS-FT.
