AREA FORECAST DISCUSSION...UPDATED FOR AVIATION NATIONAL WEATHER SERVICE FORT WORTH TX 500 AM CST WED NOV 17 2004 .AVIATION... AS MENTIONED PER DISCUSSION BELOW...LOOKS LIKE TOUGH FCSTS FOR AREA TAF SITES TODAY. GENERAL THINKING IS THAT WITH DRY PUNCH NOW MOVING UP THROUGH THE RIO GRANDE VALLEY TWD N TX...THAT VFR CONDS/-RA OR -TSRA SHOULD PREVAIL...WITH THE TEMPO MVFR CONDS/MOD-HVY RA OR TSRA BR THROUGH 00-03Z THURS...BEFORE WARM CONVEYOR BELT AHEAD OF UPPER LOW MOVES EAST OF N TX AIRPORTS.

OTRW...SE WNDS 5-15 KTS CONT FIRST 12-18 HRS...BEFORE VEERING W/SWLY 4-8 KTS...AS SFC LOW EJECTS INTO OK IN RESPONSE TO UPPER LO MOVING NEGATIVELY TILTING UP THAT WAY AS WELL. 05/ && .PREV DISCUSSION... 258 AM CST WE HAVE EXTENDED THE FLOOD WATCH EAST TO INCLUDE DENTON & COLLIN COUNTIES PLUS POINTS SOUTH...AND HAVE CANCELED IT IN FAR WESTERN COUNTIES. EVIDENCE FOR HEAVY PRECIP NOT AS STRONG AS EARLIER WITH MUCH OF THE MOISTURE RAINING OUT IN HOUSTON CWA BUT QPF PROGS SHOW DECENT ACCUMULATIONS. IN ADDITION...IN NOVEMBER NOT MUCH IS GROWING EXCEPT WEEDS IN MY YARD...PLUS THE GROUND IS ALREADY WET ADDING TO RUNOFF POTENTIAL. THE METROPLEX IS A BIT NORTH OF THE HEAVIEST QPF BUT ADDED IT DUE TO ALL THE CONCRETE ENHANCING RUNOFF. UPPER LOW TO KICK OUT TO THE NORTHEAST ACROSS CWA TODAY AND TONIGHT. MOVEMENT ON THIS MODEL RUN IS FASTER THAN PREVIOUS...AND CURRENT RADAR LOCATION OF PRECIP COMPARED TO OLD MODEL RUN SUPPORTS THIS. RESULT...I HAVE DRIED US OUT QUICKER THAN PREVIOUS PACKAGE. RAIN SHOULD EXIT CWA THURSDAY AFTERNOON WITH ONLY LINGERING SHOWERS IN EAST AFTER THURSDAY MORNING. NEXT CHANCE FOR RAIN LOOKS LIKE SATURDAY AND SUNDAY AS MOISTURE STARTS TO RETURN FROM THE GULF. NO STRONG UPPER SYSTEM TO SUPPORT WIDESPREAD PRECIP BUT THERE IS A BIT OF A REINFORCING SHOT OF COOL AIR ON SUNDAY TO PROVIDE SOME LIFT ALONG THE FRONT. NEXT UPPER LOW MOVES ACROSS AREA TUESDAY NIGHT THROUGH WEDNESDAY NEXT WEEK. AT THIS TIME IT LOOKS STRONG ENOUGH TO MAKE WIDESPREAD PRECIP BUT WILL KEEP POPS DOWN TO CHANCE BASED ON POOR TIMING AND UNCERTAINTY OF UPPER LOW TRACK. && .PRELIMINARY POINT TEMPS/POPS... DALLAS-FT.
