SUNSHINE OVER THE MOUNTAINS ALLOWED THE AREA TO BECOME VERY

BOUNDARIES FROM CURRENT ACTIVITY MOVE IN. WILL GO CATEGORICAL OVER
THE MTNS AND NC FOOTHILLS WHERE CONVECTION ONGOING OR IMMINENT...
LIKELY ELSEWHERE. FLOOD THREAT CONTINUES WITH HEAVY RAINERS AND SLOW

SCATTERED. A REMINDER...FIRST PERIOD POP BELOW IS CCF AND NOT
CURRENT COVERAGE.
