.
SATELLITE ANALYSIS AND TRENDS...GOES WV IMAGERY ANIMATION SHOWS UPPR
CIRC ALONG THE MX BORDER INVOF OF S PRESIDIO/SW BREWSTER COUNTIES. THE WV
IMAGERY ALSO SHOWS THAT LARGE SCALE FLOW AROUND UPPR CIRC HAS BEEN DRAWING
MID/UPPR LVL TROPICAL MOISTURE ASSCD WITH TS HENRIETTE NEWD ACRS MX INTO
S TX. AT THE SAME TIME PW'S RANGING UP TO VALUES IN EXCESS OF 2.3" OVER
THE WRN GULFMEX..PER AMSU DATA..ARE BEING ADVECTED ACRS SE/S TX BY 850MB
SERLY WINDS. LATEST IR IMAGERY SHOWS THAT SW-NE LN OF CNVTN HAS RAPIDLY
DEVELOPED OVER MC MULLEN/LA SALLE/WEBB COUNTIES. INITIAL DEVELOPMENT
WAS OVER MC MULLEN COUNTY AROUND 2130Z..WITH CLOUD TOPS RAPIDLY COOLING
TO -60C BY 22Z. MANUAL STLT ESTIMATES INDICATE THAT OVER AN INCH FELL
IN THAT HALF HR PERIOD. IN THE HALF HR SINCE..2200Z-2240Z..ENHANCED
IR CLOUD TOPS HAVE BUILT SWWD INTO LA SALLE COUNTY..WITH VIS IMAGERY
SHOWING TCU/LOW TOP CB'S DEVELOPING OVER N WEBB AND DIMMIT COUNTIES.
.
IN ADDITION TO HVY RAIN BURSTS IN SHORT PERIODS OF TIME..THE CONCERN GOING
FORWARD IS THAT IN THE GENERAL VCNTY OF DIMMIT/LA SALLE/WEBB COUNTIES A
CONVECTIVE WEDGE MAY SET UP THIS EVE/TONIGHT..RESULTING IN A PROLONGED
PERIOD OF HVY RAIN. LL WINDS ARE ON THE LIGHT SIDE..AND WITH SURGE OF
MID/UPPR LVL TROPICAL MOISTURE FM MX..CONDITIONS ARE FAVORABLE FOR THAT
TO OCCUR. NOT A CERTAINTY..BUT A GOOD POSSIBILITY GIVEN THE PATTERN.
