EVENT...MAJOR HEAVY RAIN EVENT CONTINUES FOR RATHER LARGE REGION EXTENDING
FROM N CENT TO S CENT TX AS MCS OUTFLOW BOUNDARIES MERGE.
.
SATELLITE ANALYSIS AND TRENDS...AFTER VIEWING SOME OF THE GAUGE DATA
ON THE LCRA.ORG SITE FOR APPROXIMATE REGION AROUND BURNET/EXTREME N
TRAVIS/LLANO COUNTIES WHICH SHOW SOME 3 HOUR TOTALS OF OVER A FOOT CANNOT
EMPHASIZE ENOUGH THE POTENTIAL OF SOME OF THESE BATCHES OF CONVECTION
IN THIS EXTREMELY MOIST ENVIRONMENT OVER TEXAS. NOW ALSO AWAITING AN
INEVITABLE AND VERY SIGNIFICANT MERGER BETWEEN SEVERAL DIFFERENT BATCHES
OF CONVECTION/OUTFLOW BOUNDARIES. BEFORE THIS MERGER OCCURS EXPECT THE
LINE OVER S CENT TX TO CONTINUE ITS DRIFT TO THE SOUTH AND WEST WHICH
SHOULD RESULT IN A HIGH LIKELIHOOD OF SEVERAL INCHES OF RAIN FOR THE
REGION FROM MCCULLOCH/SAN SABA SOUTHEASTWARD TO BLANCO COUNTY DURING THE
NEXT HALF HOUR TO HOUR OR SO. IR/RADAR TRENDS ALSO INDICATE A SOUTHWARD
MOVEMENT TO VERY COLD TOPPED BATCH OF INTENSE CONVECTION EXTENDING
FROM JONES TO EASTLAND COUNTY WHILE THE LEADING EDGE OF EASTWARD MOVING
OUTFLOW FROM W TX COMPLEX IS ALSO CONVERGING ON THE REGION. AS MERGERS
OCCUR BETWEEN THE 3 MAIN AREAS OF CONVECTION EXPECT A MORE CONSOLIDATED
COMPLEX TO FORM WITH INTENSE RAIN RATES TO AT LEAST 3"/HR OR HIGHER FOR
APPROXIMATE REGION FROM COLEMAN/BROWN COUNTIES SOUTHWARD TO MASON COUNTY
SOMETIME WITHIN THE NEXT HALF HOUR TO HOUR. BELIEVE THAT THE CONSOLIDATED
COMPLEX WILL THEN MOVE TO THE SOUTHEAST. AN ANNOTATED SATELLITE GRAPHIC
DEPICTING THE THREAT AREA WILL BE POSTED ON THE INTERNET ADDRESS LISTED
BELOW IN APPROXIMATELY 10 MINUTES.
