NWS Fort Worth, TX wrote its last area forecast discussion before the first event at May 10, 5:12 PM CST, 33 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE FORT WORTH TX 612 PM CDT SAT MAY 10 2008 .AVIATION UPDATE... DRYLINE JUST WEST OF KDFW AND WILL BEGIN TAF WITH WEST WIND AS THIS BOUNDARY SHOULD MOVE THRU DFW PRIOR TO 00Z. SECONDARY WINDSHIFT TO A NORTHWEST DIRECTION WILL AFFECT METROPLEX TAFS AROUND 02Z BASED ON BOUNDARY EXTRAPOLATION FROM RADAR TRENDS. THREAT OF THUNDERSTORMS HAS ENDED AT ALL BUT KACT...BUT PROBABILITY IS VERY LOW AND HAVE LEFT MENTION OF THUNDER OUT OF KACT TAF. WILL MONITOR SHORT-TERM TRENDS FOR POSSIBLE TAF UPDATE. THREAT OF THUNDERSTORMS AT KACT WILL END BY AROUND 04Z AS DRYLINE/WEAK COLD FRONT MOVES THROUGH. NO SIGNIFICANT WEATHER REMAINDER OF TAF PERIOD. 07/BB && .DISCUSSION... 251 PM CDT UPPER LEVEL SHORTWAVE TROUGH BEGINNING TO AMPLIFY AS IT MOVES ACROSS THE PLAINS...WITH SURFACE DRY LINE NOW ENTERING THE WESTERN ZONES. 18Z SOUNDING SHOWS SUBSTANTIAL CAP...BUT WITH TEMPERATURES EXPECTED TO WARM INTO THE LOW TO MID 90S...CIN WILL WEAKEN SUFFICIENTLY FOR ISOLATED TO SCATTERED STORMS TO DEVELOP. THE MOST FAVORED LOCATION WILL BE ACROSS THE NE ZONES WHERE DYNAMIC FORCING FROM SHORTWAVE WILL BE CLOSER. RUC FORECASTS WERE USED FOR POSITIONING OF THE DRY LINE LATE THIS AFTERNOON AT THE TIME OF INITIATION...ALONG A LINE FROM GAINESVILLE TO ARLINGTON TO HILLSBORO TO LAMPASAS. LOCATIONS ALONG AND EAST OF THE DRY LINE HAS AT LEAST A SLIGHT RISK OF SEVERE WEATHER THROUGH MIDNIGHT. EXTREME INSTABILITY IS FORECAST...WITH MIXED LAYER CAPE EXCEEDING 3500 J/KG AND STRONG DEEP LAYER SHEAR OF 60-70 KT. OBVIOUSLY VERY LARGE HAIL AND DAMAGING WINDS WILL BE A THREAT. DESPITE THE WEAK LOW LEVEL SHEAR...HIGH INSTABILITY WILL COMPENSATE AND ALLOW FOR AN ISOLATED TORNADO THREAT AS WELL. STORMS WILL MOVE OFF INTO EAST TEXAS LATER THIS EVENING...AND SEVERE WEATHER THREAT SHOULD END BY MIDNIGHT ACROSS THE CWA WITH LOSS OF DIURNAL HEATING. STRONG COLD FRONT MOVES THROUGH THE AREA OVERNIGHT WITH NORTH WINDS INCREASING TO 15 TO 25 MPH. TEMPERATURES WILL FALL INTO THE 50S BY SUNRISE...WITH A MUCH COOLER DAY EXPECTED TOMORROW. WINDS WILL SUBSIDE AND SKIES WILL CLEAR DURING THE AFTERNOON AND SET THE STAGE FOR A VERY COOL NIGHT. LOWS MONDAY MORNING WILL FALL INTO THE MID 40S TO LOWER 50S. GENERALLY NICE WEATHER IS EXPECTED MONDAY...BUT WINDS WILL RETURN TO THE SOUTH BY MONDAY NIGHT WITH CLOUDS AND MOISTURE ON THE INCREASE. THE NEXT SYSTEM WILL CLOSE OFF AND SWING THROUGH THE SOUTHERN ROCKIES TUESDAY. THIS SYSTEM WILL SEND A DRY LINE INTO THE WESTERN COUNTIES TUESDAY AFTERNOON WHICH MAY PROVIDE THE FOCUS FOR SCATTERED THUNDERSTORMS. HOWEVER...THE BEST CHANCE OF RAIN AND STORMS WILL COME TUESDAY NIGHT AND WEDNESDAY AS THE UPPER LOW MOVES OVER TEXAS. COPIOUS MOISTURE COMBINED WITH LIFT ALONG AND AHEAD OF A SLOW MOVING COLD FRONT MEANS SOME WIDESPREAD/HEAVY RAINFALL IS POSSIBLE WITH THIS SYSTEM. HIGHLY AMPLIFIED UPPER LEVEL FLOW WILL KEEP THINGS GENERALLY MOSTLY CLOUDY AND COOL WITH A DEEP TROUGH TRANSPORTING CANADIAN AIR INTO THE MIDWEST. SOME LOW CHANCES OF RAIN WILL BE POSSIBLE THURSDAY AS THE TROUGH AXIS SWINGS THROUGH...BUT IT IS A BIT QUESTIONABLE ATTM. TEMPERATURES WILL SLOWLY MODERATE BY NEXT WEEKEND TO NEAR NORMAL.
