SOUTHEAST JIM HOGG COUNTY. THE RAIN AND STRONG WINDS HAVE LET UP
IN BRO...AND SHOULD BE CLEAR OF HARLINGEN BY MIDMORNING. WITH ALL
THIS AMPLE MOISTURE IN PLACE...ANY HEATING THAT DOES OCCUR FROM
BREAKS IN THE CLOUDS MAY ALLOW AN OUTER BAND TO REFORM...BRINGING
ANOTHER ROUND OF THUNDERSTORMS. THE REMNANTS OF DOLLY WILL
CONTINUE WEST INTO THE BIG BEND REGION. HIGH PRESSURE TO THE NORTH
WILL BUILD INTO THE EASTERN HALF OF TEXAS...CAPPING ANY MOISTURE
LEFT OVER AFTER FRIDAY.
