CURRENTLY DRYLINE HAS PUSHED TO THE EAST OF THE CWA.  18Z SURFACE
ANALYSIS HAD IT JUST WEST OF A DRT TO SJT TO ABI LINE.  RUC/NGM/ETA
ALL INDICATE THAT IT WILL MAKE A RETREAT LATER THIS EVENING INTO
PORTIONS OF THE EASTERN CWA.  AT THIS TIME AM NOT ANTICIPATING ANY
THUNDERSTORM DEVELOPMENT WITHIN THE CWA TONIGHT.  COLD FRONT
CURRENTLY LOCATED OVER WESTERN NEW MEXICO WEST OF AN ELP TO ABQ LINE
IS NOT MOVING MUCH...THINK THAT CURRENT MODEL FORECAST ON MOVEMENT OF
THE FRONT MAY BE CONSIDERABLY TOO FAST.

ALL MODELS A VERY SIMILAR IN THEIR RESPECTIVE TRACK OF THE UPPER
LEVEL LOW...ALL SEEM TO BE INDICATING THAT LOW WILL TAKE A MORE
NORTHERLY TRACK AND WEST TEXAS MAY NOT SEE ANY MORE OUT OF THIS
SYSTEM EXCEPT FOR A FEW MID TO HIGH LEVEL CLOUDS.  TOMORROW WILL BE
COOLER THAN TODAY AS THICKNESS VALUES FALL BEHIND THE PACIFIC FRONT.
SUNDAY SHOULD BE EVEN WARMER AS UPPER LEVEL SYSTEM MOVES TO THE NORTH
OF AREA AND SOUTHWESTERLY LOW LEVEL FLOW RETURNS TO WEST TEXAS.
