Area forecast discussion, Apr 2, 1:38 PM CST, 6 hours 54 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIDLAND TX 137 PM CST (1237 PM MST) FRI APR 2 1999 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.
