EVENT...WELL DEFINED VORT AND VERY HIGH MOISTURE...LITTLE MOVEMENT...SMALL
AREA OF EXCESSIVE RAIN POSSIBLE MOST OF THE NIGHT...
.
SATELLITE ANALYSIS AND TRENDS...CIRCULATION OVER MEXICO PAST FEW DAYS
HAS MOVED INTO S TEXAS THIS EVENING.  ALMOST HAS THE FEEL OF A TROPICAL
DISTURBANCE IF IT WAS LATER IN THE SUMMER...BUT WELL DEFINED VORT TWIST
IN LOOP AND ENCOUNTERING VERY HIGH PW MOISTURE FROM KBRO TO KCOT AND
VORT MAKING THE MOST OF THE HIGH MOISTURE BY PRODUCING EXCESSIVE RAINS
LASALLE INTO FRIO AND NOW EXPANDED INTO MEDINA COUNTY.   IF THE COMPLEX
CAN MOVE OR KEEP EXPAND NORTH...FF THREAT CAN BE MINIMAL OVERNIGHT...BUT
AM CONCERNED DRY AIR/LOW PWS OVER THE SW LA AND LOW PWS OVER NEW MEXICO
COULD WEDGE THIS CONVECTION INTO S TX AND NOT LET IT MOVE OUT OF THE
AREA...SO IT COULD SIT AROUND MOST OF THE NIGHT NEAR OF JUST WEST OF
SAN ANTONIO.   COLDEST CLOUD TOP AT 03Z NEAR -70C AND EQUILIBRIUM LEVEL
TEMPS NEAR -62C...SO ANY COOLING TOPS COLDER THAN -62C WILL RESULT IN
EXCESSIVE RAINS AND DEFINITE FF POTENTIAL.    WILL CONTINUE TO MONITOR...
