AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FORT WORTH TX
330 PM CDT SUN MAY 6 2001

THE 18Z FWD SOUNDING SHOWED A LITTLE CAPPING...BUT HEATING THIS AFTERNOON
WILL BE SUFFICIENT TO BREAK THROUGH THE CAP.  THUNDERSTORMS HAVE ALREADY
DEVELOPED ACROSS THE EXTREME SOUTHWESTERN ZONES.  ADDITIONAL ACTIVITY
WILL BE FORMING ALONG THE DRY LINE WEST OF A BOWIE TO ABILENE LINE
SHORTLY.  HAVE GONE WITH LIKELY POPS FOR TONIGHT MOST OF THE FORECAST
AREA AS THIS ACTIVITY SHOULD TREK EAST ACROSS THE REGION OVERNIGHT.
THE COLD FRONT THAT EXTENDED FROM SOUTH CENTRAL KANSAS...INTO EAST
CENTRAL NEW MEXICO...WILL MOVE SOUTHEAST INTO NORTH TEXAS LATE
TONIGHT.  THIS FRONT LOOKS LIKE IT WILL STALL ACROSS NORTH TEXAS...
SO WITH THE NORTHWESTERLY FLOW ALOFT WILL KEEP A CHANCE OF THUNDERSTORMS
IN THE FORECAST.  THIS BOUNDARY WILL START TO MOVE BACK NORTH BY
LATE TUESDAY.    #58
