SATELLITE ANALYSIS AND TRENDS...CENTRAL TX AND VCNTY AND NE TX... WV
IMAGERY SHOWS UPPR CIRC OVER CENTRAL TX NR JCT..WITH DEFORMATION AXIS
TO THE N STRETCHING FM SE OK THRU NW TX. STLT IMAGERY SHOWS SEVERAL
AREAS OF SLOW MOVG WARM TOP TSTMS ASSCD WITH THESE FEATURES. NR OR
JUST S OF DEFORMATION AXIS A FEW CLUSTERS ARE NOTED OVER SE OK COUNTY
OF MC CURTAIN AND OVER TX TO THE NE OF DAL. THE MOST PERSISTENT CELLS
HAVE BEEN OVER HUNT COUNTY..WHERE MANUAL STLT EST INDICATE BTWN 2-3"
OF RAIN FM 1045Z-1445Z. OTHER BTWN DAL AND SE OK HAVE BEEN OF SHORTER
DURATION..BUT DUE TO VERY HIGH PW VALUES AROUND 2"..STLT EST INDICATE
AN INCH OF RAIN IN LESS THAN AN HR.  TO THE SW..NR UPPR LOW..WARM TOP
TSTMS HAVE BEEN DEVELOPING BTWN SEP AND N OF JCT. WITH RELATIVELY LT
FLOW ALOFT AROUND UPPR LOW..THE CONCERN HERE FOR THIS MORNING/AFTN FOR
SLOW MOVG/MERGING TSTMS. ANOTHER DEVELOPING AREA OF TSTMS IS OCCURRING
S OF JCT. AS DAYTIME HEATING CONTINUES TO KICK IN..THE CONCERN IS THAT
CONVECTION WILL FILL IN FURTHER ACRS THE AREA INCLUDING CENTRAL/S
CENTRAL/S TX.  GOES SOUNDER INDICATED PW'S RANGING BTWN 1.8-2" HERE
AS WELL. STLT TRENDS AND HIGH PW'S RAISE POSSIBILITY OF A NUMBER OF
LOCATIONS VULNERABLE TO 2" OR MORE IN AN HR TODAY..AND ANY PERSISTENT
OR REPEATED ACTIVITY OVER A GIVEN LOCATION CAN PRODUCE 2-4" TOTALS.
.
DEEP S TX AND SE TX COAST...MCC HAS PERSISTED OVER WRN GULFMEX FOR
A NUMBER OF HRS. IN THE PAST 1-2 HRS..STLT IMAGERY HAS SHOWN SOME
BACKBUILDING ALONG THE WRN EDGE. THIS HAS BEEN MOST NOTICEABLE FM
SW OF PSX TO VCNTY OF NGP. BACK EDGE INVOF SAN PATRICIO COUNTY IS NOW
BEGINNING TO MERGE WITH CELLS MOVG N AND NEWD ACRS KENEDY/KLEBERG/ NUECES
COUNTIES. ADDITIONAL TSTMS HAVE BEEN FORMING TO THE S..OVER HIDALGO
COUNTY..AND OVER MX NR THE CAMERON COUNTY BORDER.  UNFORTUNATELY..THIS
AREA FM HIDALGO/CAMERON COUNTIES TO SAN PATRICIO COUNTY WILL CONTINUE TO
BE THE FOCUS OF TRAINING AND MERGING TSTMS INTO THIS AFTN. GOES SOUNDER
IMAGERY..IN ADDITION TO 2"PLUS PW'S..SHOWS HIGH AND PERSISTENT INSTABILITY
OVER THE AREA AS WELL. LL FLOW WITH SRLY AND ERLY COMPONENT CONTINUES TO
FEED INTO THE AREA..WITH LATEST OBJECTIVE ANALYSIS SHOWING STRONG SFC
CONVERGENCE OVER THE DEEP S AND LOWER TX COASTAL COUNTIES. LATEST STLT
TRENDS SUGGEST THAT A NUMBER OF LOCATIONS HAVE THE POTENTIAL TO RECEIVE
SEVERAL INCHES OF RAIN DURING THE DAY.
