SATELLITE ANALYSIS AND TRENDS...

DEEP S TEXAS...OF MOST CONCERN ATTM THE MCS ACROSS DEEP SOUTH TEXAS
CONTINUES TO BE FEED BY TROPICAL GOM CU STREAMERS THAT DEVELOP RAPIDLY
OVER BROOKS COUNTY AND WITH SLOW PROPAGATION OF THE COMPLEX SOUTHWARD
SLOWLY. RECENT VERY COLD TOPS TO -75 COULD BE SEEN OVER S BROOKS WITH
ESTIMATED RATES AS HIGH AS 3"/HR WITH OLDER THUNDERSTORMS MOVING N
AND NE AND WARMING INTO A NICE MCS SHIELD WITH SOLID MODERATE RAINFALL
PRODUCTION.  THE GOOD NEWS HERE IS THAT THE CU STREAMERS HAVE WEAKENED
OVER THE BROWNSVILLE AREA INDICATING SLIGHTLY LOWER PWS FROM THE 2.25
TO 2.0" PER GOES SOUNDER.

SOUTH CENTRAL TEXAS...IR LOOP SHOWS THE COMPLEX OVER THE EASTERN EWX
CWA HAS BEEN WARMING OVER THE LAST FEW IMAGES...BUT VIS LOOP SHOWS THAT
THOUGH THERE IS SOME GLACIATION INDICATING WEAKENING...NEW OVERSHOOTING
TOPS CAN BE SEEN DEVELOPING ALONG THE EASTER PERIPHERY LIKE IN FAYETTE
AND LEE COUNTIES AS WELL AS FURTHER SOUTH ALONG THE COAST... UPPER LEVEL
OUTFLOW IS QUITE GOOD IN THIS AREA AS SEEN BY THE CIRRUS STREAMERS THAT
TURN TOWARD LA...AIDING CONTINUED DEVELOPMENT THROUGHOUT THIS AFTERNOON
INTO EVENING

WESTERN SOUTH TEXAS...COLD POOL THAT HAS FORMED FROM THE TWO MCS OVER
SOUTH CENTRAL TEXAS HAS LEAD TO AN OUTFLOW BOUNDARY TO DEVELOP AND BEGIN
TO CONVECT... FIRST IN C DIMMIT COUNTY THEN IN N WEBB/S LA SALLE COUNTIES.
THESE CELLS LOOK QUITE STRONG ON VISIBLE IMAGERY WITH GOOD EXPANSION
AND COOLING SEEN IN IR AS WELL. THESE CELLS ARE LIVING OFF HIGH MOISTURE
(2.33" PW PER GOES SOUNDER) THAT HAS BEEN MOVING UP THE RIO GRANDE AND
ALONG THE EASTERN SLOPES OF HIGHER ELEVATION IN N MX AVOIDING THE DEEP
S TX COMPLEX. THESE CELLS WILL CONTINUE TO SHIFT WESTWARD TO THE RIVER
MOST LIKELY CUTTING OFF THE BEST MOISTURE TO WEAK CELLS DEVELOPING FROM
REAL AND NORTH ALONG THE OUTFLOW BOUNDARY THOUGH WITH LOW FFG VALUES
UP THERE THE LIMITED DEVELOPMENT MAY STILL BE ENOUGH TO ECLIPSE SHORT
DURATION GUIDANCE TOTALS IN STRONG DOWNPOURS.
