HEAT ADVISORY IN EFFECT THROUGH 7 PM

LIBERTY, August 19, 2010 - TODAY AND TONIGHT A HEAT ADVISORY REMAINS IN EFFECT FOR EXPECTED HEAT INDEX VALUES UP TO 105 THIS AFTERNOON. RELIEF FROM THE HEAT IS POSSIBLE AS THUNDERSTORMS DEVELOP ACROSS MOST OF SOUTHEAST TEXAS. AREAS ALONG AND SOUTH OF A LINE FROM BRENHAM TO LIVINGSTON COULD SEE BETTER RAINFALL COVERAGE. THERE IS A SLIGHT RISK FOR STRONG THUNDERSTORMS PRODUCING GUSTY WINDS AND HEAVY DOWNPOURS.

FRIDAY THROUGH SUNDAY HOT AND HUMID CONDITIONS WILL RETURN. HIGH TEMPERATURES FROM THE MID 90S AT THE COAST TO NEAR 100 WELL INLAND ARE EXPECTED. HEAT INDEX VALUES WILL LIKELY TOP 105 EACH AFTERNOON.

MONDAY THROUGH WEDNESDAY RELIEF FROM THE HEAT IS POSSIBLE BY TUESDAY. HIGH TEMPERATURES ARE EXPECTED TO COOL SLIGHTLY TO RANGE FROM THE LOWER 90S AT THE COAST TO UPPER 90S WELL INLAND. HOWEVER...THE HEAT INDEX MAY AGAIN REACH OR TOP 105 WITH INCREASED HUMIDITY. THERE IS A SLIGHT CHANCE FOR THUNDERSTORMS EACH DAY.
