215 PM CST MON JAN 6 1997

AGREE THAT SE TX WX WILL STAY CLOUDY...WINDY AND COLD THROUGH THIS
FCST PERIOD.  WITH THE VERY IMPRESSIVE LOOKING UPPER LOW TO OUR WEST
MOVING TO THE EAST ONLY VERY SLOWY THE NEXT 48H...THE GOOD FEED OF
PACIFIC MOISTURE WITH EMBEDDED PULSES TO CONTINUE.  STRONG CAA AT THE
SFC TO ALSO CONTINUE THE NEXT COUPLE OF DAYS OR SO.  ANOTHER SFC
FEATURE OF NOTE IS THE DEEPENING LOW OFF THE LOWER TX COAST.  THIS
SYSTEM IS PROGGED TO MOVE TO THE NE (UP THE COAST) THRU THE PD -
AIDING IN THE DEVELOPMENT OF ADDITIONAL SHRA/+SHRA ON WED.  GIVEN THE
GOOD DYNAMICS AND AVAILABLITY OF A DEEP LAYER OF MOISTURE...MAIN FCST
PROBLEM IS THEN THE POSSIBILITY OF ANY WINTER-TYPE PCPN.  FOR TONIGHT
/EARLY TUE MORNING...PROBABLY NOT AS THE MID LEVELS ARE PROGGED TO
REMAIN TOO WARM.  NEXT BEST CHC APPEARS TO BE TUE NIGHT/WED MORNING -
ESPECIALLY FOR THE NRN ZONES.  ATTM...WOULD LIKE TO HOLD OFF ON ANY
MENTION OF A WSW FOR SE TX AS THIS IS STILL A BIT OFF AND LET LATER
SHIFTS EVALUATE FURTHER WITH ANOTHER MODEL RUN UNDER THEIR BELTS.
HOWEVER...AM PLAYING WITH THE IDEA OF AN SPS AS A HEADS UP.  WILL
TREND TEMPS TOWARD THE SLIGHTLY WARMER FWC NUMBERS.  41
