NWS Fort Worth, TX wrote its last area forecast discussion before the first event at Sep 30, 10:48 PM CST, 1 hour 12 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE FORT WORTH TX 1148 PM CDT WED SEP 30 2009 .AVIATION... /6Z UPDATE/ SOUTHERLY FLOW CONTINUES TONIGHT AROUND 15KTS MOST AREAS AND WITH SUFFICIENT LOW LEVEL MOISTURE SPREADING NORTHWARD...EXPECT MVFR CIGS BKN/OVC015 TO OVERSPREAD THE AREA AFTER MIDNIGHT. LOW CLOUDS SHOULD LINGER THROUGH MUCH OF THE MORNING. MODEL GUIDANCE STILL INDICATING WEAK LIFT THROUGH MORNING WITH SOME WEAK ELEVATED INSTABILITY WHICH COULD LEAD TO SOME SCATTERED SHOWERS BEFORE MIDDAY. COLD FRONT STILL EXPECTED TO ARRIVE WITH WIND SHIFT AROUND 02/00Z. GUIDANCE CONTINUES TO SUGGEST CAP STRENGTH TO REMAIN SUFFICIENTLY STRONG THROUGHOUT MUCH OF THE DAY WITH BULK OF CONVECTIVE ACTIVITY DEVELOPING FARTHER EAST AFTER FRONTAL PASSAGE. HAVE MADE SOME MINOR ADJUSTMENTS TO TIMING...AND WILL CONFINE VCTS TO 01/22Z-02/00Z IN THE METROPLEX. WIND SHIFT WILL BE LATER AT WACO WITH SLIGHTLY BETTER TSTM CHANCES. NORTH FLOW AND CLEARING SKIES/VFR CONDITIONS EXPECTED BEHIND THE FRONT. 91/DUNN && .UPDATE... WITH THE EVENING UPDATE MADE A COUPLE OF CHANGES TO TOMORROWS WEATHER FORECAST. 00Z FWD SOUNDING INDICATES A WARM LAYER IN BETWEEN H800 AND H700. THIS REPRESENTS A CAP TO CONVECTIVE POTENTIAL THAT FORECAST SOUNDINGS INDICATE WILL HOLD OVER THE FORECAST AREA OVER THE NEXT 24 HRS. WITH THIS CAP IN PLACE FEEL THAT STRONG LOW LVL FORCING WILL BE NECESSARY FOR CONVECTIVE INITIATION TOMORROW. THE COLD FRONT MOVING THROUGH THE FORECAST AREA LATE TOMORROW AFTERNOON AND THEN INTO THE EVENING HOURS SHOULD PROVIDE SUFFICIENT FORCING THRU THIS LAYER TO ALLOW TSTMS TO DEVELOP. WITH THIS IN MIND...WENT AHEAD AND REMOVED MENTION OF WX FROM THE FORECAST FOR THE MORNING HRS AND SPREAD CHANCE POPS OVER THE NORTHERN HALF OF THE CWA FOR THE AFTERNOON HRS. MODELS CONTINUE TO INDICATE THAT THE BEST LARGE SCALE SUPPORT WILL REMAIN NORTH OF TX...KEEPING THE BEST CHANCES FOR SVR WX NORTH INTO EASTERN OK AND THRU AR. FORECAST SOUNDINGS INDICATE 1000-1500 J/KG OF MUCAPE COUPLED WITH 35 TO 40 KTS OF DEEP LAYER SHEAR OVER NORTH TX TOMORROW AFTERNOON THROUGH TOMORROW EVENING...SO SVR WX REMAINS POSSIBLE...BUT NOT AS LIKELY TO BE WIDESPREAD. REGARDLESS...WENT AHEAD AND ADDED SEVERE WORDING TO THE AFTERNOON TSTM CHANCES. WOULD ANTICIPATE PRIMARY SEVERE WEATHER HAZARDS WILL BE LARGE HAIL AND DAMAGING OUTFLOW WINDS. DO NOT ANTICIPATE ANY WIDESPREAD HEAVY RAINFALL/FLOODING AS THE COLD FRONT LOOKS TO BE FAIRLY PROGRESSIVE PREVENTING STORMS FROM HOLDING OVER ANY ONE LOCATION FOR A LONG PERIOD OF TIME. OTHERWISE FORECAST IN PRETTY GOOD SHAPE AND NO OTHER SIGNIFICANT CHANGES WERE MADE. SATURDAY NIGHT/SUNDAY MORNING STILL LOOKS INTERESTING WITH TROPICAL PACIFIC MOISTURE MOVING OVER NORTH TX IN THE MID LVLS OF THE ATMOSPHERE WHILE GULF MOISTURE RETURNS TO THE REGION AS TOMORROWS COLD FRONT LIFTS BACK NORTH. PWATS LOOK TO INCREASE TO NEARLY 2 STANDARD DEVIATIONS ABOVE NORMAL...POINTING TO A POTENTIAL FOR HEAVY RAINFALL ACROSS THE REGION. MAIN POINT OF CONTENTION THIS EVENING APPEARED TO BE THE GFS NOT INDICATING ANY LARGE SCALE FORCING MECHANISM FOR RAINFALL DURING THE PERIOD WHILE THE ECMWF BRINGS A SHORTWAVE TROUGH THRU THE REGION. IF THE SHORTWAVE TROUGH DOES MOVE THRU THE REGION WITH DEEP TROPICAL MOISTURE IN PLACE HEAVY RAINFALL OVER THE AREA IS VERY LIKELY. WILL HAVE TO MONITOR THE SITUATION AS THE WEEKEND APPROACHES TO DETERMINE LIKELIHOOD OF HEAVY RAINFALL FOR NORTH TX. CAVANAUGH && .PREV DISCUSSION... /ISSUED 300 PM CDT WED SEP 30 2009/ 70S DEW POINTS HAVE MADE IT INTO SOUTHERN COUNTIES NOW...AND SHOULD BE IN PLACE ACROSS THE AREA FOR THE THURSDAY FRONT. BY MORNING WIDESPREAD STRATUS WILL LIE OVER NORTH TX...AND SOME ELEVATED SHOWERS/FEW THUNDERSTORMS SHOULD BE EVIDENT IN THE MIX AS WELL. IF PRECIP IS MORE WIDESPREAD IN THE MORNING...HEATING WILL BE LIMITED AND THE AFTERNOON INSTABILITY WILL BE DECREASED. IF THE CLOUDS TAKE LONGER TO BURN OFF THAN TODAY...THAT WILL ALSO LIMIT HEATING. MODELS ALSO SHOW WEAKER WIND SHEAR THAN YESTERDAY...SO ALTHOUGH THERE WILL STILL BE A SEVERE THREAT...IT WILL BE MUCH MORE LIMITED THAN IN THE OK/KS/MO/AR AREA WHERE DYNAMICS WILL BE STRONGER. MORE WIDESPREAD RAIN IS EXPECTED SATURDAY EVENING INTO SUNDAY AS A FAIRLY STRONG WAVE PULLS MOISTURE OVER THE OLD FRONT AND CREATES WIDESPREAD OVER-RUNNING RAIN. SOME EMBEDDED THUNDER IS ALSO EXPECTED...AND THERE IS ALWAYS THE POTENTIAL FOR AT LEAST NUISANCE FLOODING DUE TO THE LONGER DURATION OF THIS EVENT. WE WILL ASSESS THE FLOODING POTENTIAL MORE AS THE EVENT DRAWS NEARER. AS INDICATED IN THE PREVIOUS DISCUSSIONS...SOUTHWEST FLOW WITH EMBEDDED DISTURBANCES KEEP LOW POPS IN THE FORECAST THROUGH DAY SEVEN AS WELL. TEMPERATURES WILL BE ABOVE NORMAL THURSDAY...AND THEN COOL RAPIDLY WITH THE FRONT THURSDAY EVENING/OVERNIGHT. EXPECT COOL MORNINGS NORTH OF THE FRONT FRIDAY AND SATURDAY...BUT THERE WILL BE ENOUGH SUN TO WARM BACK INTO THE UPPER 70S/LOW 80S. TEMPERATURES SUNDAY ONWARD WILL BE MODERATED BY THE CLOUDS/RAIN CHANCES DURING THOSE PERIODS. 84 && .PRELIMINARY POINT TEMPS/POPS... DALLAS-FT.
