NWS Fort Worth, TX wrote its last area forecast discussion before the first event at Sep 24, 10:31 PM CST, 1 hour 29 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE FORT WORTH TX 1131 PM CDT MON SEP 24 2012 .AVIATION... /6Z TAFS/ VFR CONDITIONS PREVAIL TONIGHT WITH SOUTHERLY FLOW AROUND 15KTS MOST LOCATIONS. THINK SURFACE WINDS WILL STAY UP FOR MOST OF THE NIGHT WITH LOW LEVEL JET INCREASING TO NEAR 40KTS BY EARLY MORNING ACROSS THE SOUTHERN PLAINS. MAIN CONCERN TOWARD MORNING WILL BE POTENTIAL FOR SOME MVFR CIGS SPREADING NORTH FROM SOUTHEAST TEXAS. AT THIS TIME WILL CONTINUE WITH A TEMPO MVFR CIG AT WACO TOWARD SUNRISE. BETTER CHANCES FOR MORE WIDESPREAD CLOUD COVER APPEAR TO BE LIKELY EARLY WEDNESDAY MORNING. OTHERWISE... WINDS WILL REMAIN STRONG THROUGH THE DAY TUESDAY WITH GENERALLY 19025KT EXPECTED ACROSS THE AREA. SOME GUSTS IN EXCESS OF 30KTS LIKELY. NO PRECIPITATION IS EXPECTED THROUGH THE CURRENT FORECAST. DUNN && .UPDATE... HIGH CLOUDS CONTINUE TO SPREAD ACROSS THE REGION THIS EVENING. THE PREVIOUS FORECAST IS IN GOOD SHAPE AND HAVE JUST MADE ADJUSTMENTS TO THE CLOUD COVER AND HOURLY GRIDS. 58 && .PREV DISCUSSION... /ISSUED 334 PM CDT MON SEP 24 2012/ A SHIFT IN THE OVERALL WEATHER PATTERN IS UNDERWAY AS AN UPPER LEVEL DISTURBANCE DIGS THROUGH CALIFORNIA AND AIDS IN FLATTENING THE UPPER LEVEL RIDGE OVER OUR REGION. THIS SHORTWAVE IS FORECAST TO TURN EAST TONIGHT. AS THIS HAPPENS...A SURFACE LOW PRESSURE CENTER WILL DEEPEN IN THE LEE OF THE ROCKIES RESULTING IN WINDY CONDITIONS ACROSS THE REGION TUESDAY. WIND SPEEDS TUESDAY AFTERNOON WILL BE VERY NEAR WIND ADVISORY CRITERIA WITH SEVERAL LOCATIONS EXPERIENCING SUSTAINED WINDS OF 20 TO 25 MPH WITH GUSTS UP TO 35 MPH. ASIDE FROM THE WINDY CONDITIONS...THE OTHER MAIN CONCERN FOR TUESDAY WILL BE ELEVATED FIRE WEATHER CONDITIONS OVER MAINLY THE NORTHERN AND CENTRAL PORTIONS OF THE REGION. RELATIVE HUMIDITY VALUES ARE EXPECTED TO BE 25 TO 30 PERCENT IN THE NORTHERN AND CENTRAL COUNTIES BUT FINE FUELS ARE STILL HOLDING SUFFICIENT MOISTURE TO PRECLUDE ANY FIRE WEATHER HEADLINES. WE WILL CONTINUE TO HIGHLIGHT THE THREAT IN THE FIRE WEATHER PRODUCTS/GRAPHICASTS/HWO AND PRECAUTIONARY ACTIONS ARE URGED. THE FIRE WEATHER THREAT DECREASES FOR THE REST OF THE WEEK AS LOW LEVEL MOISTURE INCREASES AND WIND SPEEDS DECREASE. THE UPPER LEVEL DISTURBANCE IS EXPECTED TO STALL OVER COLORADO ON WEDNESDAY RESULTING IN NEAR ZONAL FLOW OVER THE REGION. AT THE SURFACE...A WEAK SURFACE BOUNDARY/FRONT WILL WANDER INTO KANSAS AND EVENTUALLY OKLAHOMA BY THURSDAY. THIS BOUNDARY WILL BE A FOCUS FOR SHOWER AND THUNDERSTORM DEVELOPMENT THE NEXT SEVERAL DAYS BUT MAJORITY OF THE ACTIVITY IS EXPECTED TO REMAIN NORTH AND NORTHWEST OF THE AREA. HOWEVER...WILL NEED TO MONITOR DAILY FOR RESIDUAL OUTFLOW BOUNDARIES THAT MAY WANDER CLOSE TO THE REGION...ESPECIALLY LATER IN THE WEEK. ANY OF THESE BOUNDARIES COULD BECOME A FOCUS FOR ISOLATED TO SCATTERED SHOWER/THUNDERSTORM ACTIVITY BUT OVERALL THE FORECAST SOUNDINGS SUGGEST THE DEEP LAYER ATMOSPHERIC MOISTURE CONTENT WILL BE TOO DRY AND INSTABILITY TOO LOW FOR MUCH TO DEVELOP IN OUR AREA. WITH SOUTHERLY WINDS CONTINUING THROUGH THE WEEK...LOW LEVEL ATMOSPHERIC MOISTURE WILL BE ON THE INCREASE. THE WINDS WILL STILL BE A BIT BREEZY ON WEDNESDAY BUT WIND SPEEDS WILL BE DECREASING THROUGH THE WEEK. WE FINALLY GET SOME MID AND UPPER LEVEL MOISTURE TO MOVE INTO THE REGION BY THE WEEKEND AS THE REMNANTS OF HURRICANE MIRIAM CROSSES NORTHWEST MEXICO AND MOVES NORTHWEST OF THE REGION. THESE REMNANTS WILL BE ASSIMILATED INTO AN UPPER LEVEL TROUGH DEVELOPING OVER THE NORTHERN PLAINS...BUT NOT BEFORE IT BRINGS US A CHANCE FOR RAIN FRIDAY THROUGH SUNDAY. THE ECMWF AND GFS CONTINUE TO DIFFER ON THE HANDLING OF THE REMNANTS OF MIRIAM...BUT HAVE SIDED WITH THE ECMWF WHICH HAS SUPPORT FROM THE CANADIAN AND HAS BEEN CONSISTENT FOR SEVERAL DAYS NOW. FOLLOWING THE ECMWF/CANADIAN PATTERN...CONTINUED WITH LOW POPS OVER THE WESTERN COUNTIES ON FRIDAY AS THE UPPER LEVEL REMNANTS MOVE INTO THE FOUR CORNERS REGION. THEN HAVE INCREASED POPS ON SATURDAY WITH A FRONT MOVING THROUGH THE REGION EARLY SUNDAY...BRINGING AN END TO THE RAIN. 82/JLD && .PRELIMINARY POINT TEMPS/POPS... DALLAS-FT.
