LOOKS LIKE RAIN IS FINALLY COMING TO AN END OVER OUR NWRN ZONES NEAR
COT. HOWEVER VCT MAY STILL PICK UP A FEW GOOD SHOWERS OVNT FROM APCHG
RAINBANDS.  WILL DROP POPS FOR ALL BUT VCT AREA WHERE WE WILL LEAVE
40%.  CRP 00Z SOUNDING IS STILL VERY MOIST AND VIS LOOP IDENTIFIES
COPIOUS AMTS OF MOISTURE REMAINING IN THE WRN GULF. SAT TRENDS MV
THIS MOISTURE OUR WAY AND WILL BRING A CONTINUED THREAT OF DAYTIME
SHOWERS FOR OUR REGION. BROADENING UPPER RIDGE ACROSS THE CNTRL
PLAINS MAY REDUCE RAIN CHCS FOR MON.

T.D. CHARLEY IS MVG STEADILY WWD TOWARD EAGLE PASS AND WINDS ARE
RESPONDING ACCORDINGLY.  EXPECT WINDS TO COME BACK AROUND TO THE S-SE
FOR COT AND LRD LATE.  CRP AND VCT ARE ALREADY BACK TO THE USUAL SELY
FLOW.  WILL TWEAK VCT WINDS UP A NOTCH NEAR PASSING SHOWERS.  WITH
CLOUD COVER IN PLACE...TEMPS LOOK FINE.  CWF LOOKS FINE ALSO.  BAY
WATERS COULD BE TOUGH TO NAVIGATE FROM HIGH TIDAL LVLS DRAINING INTO
THE GULF.  WINDS ALSO RUNNING 15-20 MPH RANGE.  WILL KEEP SCAS UP
FOR THE BAYS.
