.PREV DISCUSSION... /ISSUED 1119 AM CDT MON MAR 15 2010/

...SYNOPSIS...
A CLOSED LOW OVER SW NM WILL MOVE SEWD OVER THE MIDDLE RIO GRANDE
VALLEY THROUGH TONIGHT.  A BELT OF FOCUSED ASCENT E OF THE LOW
CENTER HAS BEEN CONTRIBUTING TO THE DEVELOPMENT OF A FEW ELEVATED
THUNDERSTORMS OVER W CENTRAL TX THIS MORNING /PER 12Z MAF SOUNDING
WITH MUCAPE OF 700 J/KG BASED 700-800 MB/.  THIS AREA OF CONVECTION
WILL SPREAD SEWD THROUGH THE AFTERNOON TOWARD THE EDWARDS PLATEAU. 
HOWEVER...DRIER/COOLER CONTINENTAL AIR IS SPREADING SWWD TOWARD S
CENTRAL TX...AND LOW-LEVEL MOISTURE IS UNLIKELY TO INCREASE MUCH
THIS AFTERNOON IN THE SMALL AREA WHERE CLOUD BREAKS ALLOW SOME
SURFACE NEAR AND W-S OF SAT.  GIVEN THE SUBSTANTIAL CAP NOTED IN THE
12Z DRT SOUNDING AND THE OBSERVED LOW-LEVEL MOISTURE/FLOW
CHANGES...IT APPEARS THAT ALMOST ALL OF THE CONVECTION WILL BE
REMAIN ELEVATED AND OF MARGINAL INTENSITY...SUCH THAT DAMAGING WINDS
AND HAIL AOA 1 INCH IN DIAMETER ARE UNLIKELY.
