SATELLITE ANALYSIS AND TRENDS...LATEST INFRARED AND VISIBLE SATELLITE
IMAGERY SHOWS THAT A RATHER PRONOUNCED CONVECTIVE MERGER HAS OCCURRED OVER
THE LAST 30-45 MINUTES FROM APPROXIMATELY MASON COUNTY EAST TO CORYELL
AND BELL COUNTIES.  MOST SIGNIFICANT CLOUD TOP COOLING APPEARS TO BE IN
THE VIC OF MCCULLOCH COUNTY WITH A WELL DEFINED OVERSHOOTING TOP WITH
ASSOCIATED SUBTLE ENHANCED-V SIGNATURE LOCATED OVER THE SOUTHERN HALF OF
THE COUNTY.  HAVE ALSO NOTED IMPRESSIVE CLOUD TOP COOLING WITH ANOTHER
WELL DEFINED OVERSHOOTING TOP OVER TOM GREEN COUNTY.  CONSIDERING SURFACE
TDS OF NEAR 70 AND GOES PRECIPITABLE WATERS OF 1.7" WOULD EXPECT SOME
LOCALIZED RAINFALL RATES IN EXCESS OF 2.0" IN ANY RAPID COOLING CONVECTIVE
CLOUD TOP CORES.
.
OVER THE NEXT SEVERAL HOURS IT IS QUITE POSSIBLE THAT SOUTHWARD
MOVING OUTFLOW BOUNDARY FROM MASON TO N SCHLEICHER COUNTY AND A
NORTHWESTWARD MOVING OUTFLOW BOUNDARY FROM S MASON TO MAVERICK COUNTY
WILL INTERACT.  WOULD EXPECT THAT TO OCCUR SOMEWHERE IN THE VIC OF THE
SUTTON/KIMBLE/EDWARDS COUNTY AREA SO WILL HAVE TO MONITOR THAT APPROXIMATE
AREA OVER THE NEXT HOUR OR SO FOR THE POTENTIAL FOR LOCALIZED HEAVY RAIN.
