HEAT ADVISORY IN EFFECT THROUGH 7 PM

LIBERTY, August 16, 2010 - TODAY AND TONIGHT VERY HOT AND HUMID CONDITIONS WILL CONTINUE TODAY. AFTERNOON HIGH TEMPERATURES WILL RANGE FROM THE LOWER TO MID 90S AT THE COAST TO BETWEEN 100 AND 102 WEST OF THE HIGHWAY 59 CORRIDOR. THE HEAT COMBINED WITH THE HIGH HUMIDITY WILL GENERATE HEAT INDICES FROM AROUND 105 TO 112 DURING THE AFTERNOON AND EARLY EVENING. ANYONE PLANNING OUTDOOR ACTIVITIES THIS WEEKEND SHOULD BE AWARE OF THE EXCESSIVE HEAT AND PLAN ACCORDINGLY. FREQUENT BREAKS IN AIR CONDITIONING WILL BE RECOMMENDED.

TUESDAY THROUGH SUNDAY HOT AND HUMID CONDITIONS WILL CONTINUE ON TUESDAY. AFTERNOON HEAT INDICES WILL LIKELY EXCEED 105 DEGREES. SOME RELIEF MAY OCCUR AS CHANCES FOR SHOWERS AND THUNDERSTORMS WILL INCREASE AS A STORM SYSTEM APPROACHES THE AREA FROM THE EAST...ESPECIALLY FOR LOCATIONS ALONG AND EAST OF THE INTERSTATE 45 CORRIDOR. THERE IS A SLIGHT RISK FOR DAMAGING WINDS FROM ANY STRONG STORMS THAT DO DEVELOP.

ON WEDNESDAY A WEAK UPPER LEVEL LOW WILL MOVE TOWARD TEXAS. IT IS UNCLEAR AT THIS TIME IF THE UPPER LOW WILL MOVE INTO TEXAS OR MOVE NORTH INTO LOUISIANA. THE POSITION OF THE UPPER LOW IS CRITICAL FOR RAIN POTENTIAL. AT THIS TIME...IT APPEARS THE LOW WILL MOVE NORTH AND JUST SKIRT SOUTHEAST TEXAS PRODUCING WIDELY SCATTERED SHOWERS AND THUNDERSTORMS...MAINLY EAST OF THE I-45 CORRIDOR. RAIN CHANCES WILL LINGER THROUGH THURSDAY. IF THE LOW MOVES WEST INTO TEXAS...RAIN CHANCES WILL INCREASE WITH THE POTENTIAL FOR LOCALLY HEAVY RAIN.
