.DISCUSSION...
UPPER AIR PATTERN DOES NOT CHANGE MUCH OVER THE NEXT 7 DAYS WITH
NO SIGNIFICANT FRONTAL PASSAGES LIKELY. A WSWLY SUBTROPICAL FLOW WILL
PREVAIL ALOFT WITH MOST OF THE S/W ENERGY STAYING TO OUR NORTH.
THE DRY LINE WILL APPROACH THE WESTERN CWA THE NEXT SEVERAL
EVENINGS INTO THE WEEKEND WITH ISOLD CONVECTION POSSIBLE MAINLY
WEST IN THE EVENING AND FAR NORTH AS THE CONVECTION DISSIPATES IN
THE OVERNIGHT HOURS. MODERATE TO BRISK SLY WINDS WILL PREVAIL
KEEPING HUMIDITIES UP AND TEMPS ABOVE NORMAL.

FOR NEXT WEEK...SHOULD SEE A BIT MORE UPPER RIDGING INTO TX EARLY
NEXT WEEK AND THEREFORE WARMER AND POPS 10 PERCENT OR LESS.  THE
12Z ECMWF CONTINUES TO SHOW A COLD FROPA FOR MONDAY WHILE THE GFS
STILL DOES NOT...AND WILL KEEP FORECAST AS IS WITH ABOVE NORMAL
TEMPS AND COLD FRONT REMAINING JUST NORTH OF THE CWA.  WILL
INTRODUCE LOW POPS FOR WEDNESDAY AS THE SUBTROPICAL FLOW LOOKS TO
BECOME A BIT MORE ACTIVE WITH EITHER MODEL.
