TXZ163-164-176>179-195>200-210>214-226-227-235>238-120300- HAZARDOUS WEATHER OUTLOOK NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX 315 PM CDT FRI AUG 11 2000 ...SEVERE WEATHER POSSIBLE THIS EVENING... ...ANOTHER HOT WEEKEND EXPECTED OVER SOUTHEAST TEXAS... TEMPERATURES THIS AFTERNOON EXCEEDED 100 DEGREES THIS AFTERNOON IN AN AREA FROM LUFKIN TO COLLEGE STATION...AND WILL REACH A HIGH NEAR 100 FURTHER SOUTH IN SPOTS SUCH AS CONROE AND HUNTSVILLE. EVEN THOUGH TEMPERATURES FURTHER SOUTH NEAR THE COAST ARE SLIGHTLY LOWER... HUMIDITY LEVELS ARE HIGHER...MAKING IT FEEL JUST AS UNCOMFORTABLE. THE HEAT IS MAKING THE ATMOSPHERE VERY UNSTABLE. THIS COMBINED WITH A FRONT ENTERING THE REGION FROM THE NORTHEAST WILL GENERATE SHOWERS AND THUNDERSTORMS THROUGH THIS EVENING. SOME OF THE STORMS COULD BE SEVERE...ESPECIALLY EAST OF THE BRAZOS RIVER. BE ALERT FOR THE POSSIBILITY OF DAMAGING WIND GUSTS AND HAIL IN ANY THUNDERSTORMS. THE HEAT WILL CONTINUE THIS WEEKEND. TEMPERATURES WILL BE IN THE 90S WITHIN ABOUT 50 MILES OF THE COAST...AND NEAR 100 FURTHER NORTH. THE BEST CHANCES FOR ANY SHOWERS AND THUNDERSTORMS WILL BE THIS EVENING. IF YOU ARE PLANNING TO BE OUTSIDE THIS WEEKEND...REMEMBER A FEW SIMPLE RULES TO KEEP YOU COOL IN THE HEAT... 1) DRINK PLENTY OF LIQUIDS...EXCEPT AVOID THOSE WITH ALCOHOL OR CAFFEINE. 2) WEAR LIGHT COLORED LOOSE FITTING CLOTHING. A LIGHT COLORED HAT IS ALSO A GOOD WAY TO AVOID OVERHEATING SINCE IT REFLECTS SUNLIGHT AWAY FROM YOUR HEAD. 3) TAKE FREQUENT BREAKS IN THE SHADE OR INSIDE IN AN AIR-CONDITIONED ENVIRONMENT. 4) DECREASE PHYSICAL ACTIVITY DURING THE AFTERNOON AND EVENING...WHEN TEMPERATURES ARE AT THEIR PEAK. 5) WEAR SUNSCREEN. KEEP ABREAST OF THE LATEST FORECAST FROM YOUR FAVORITE MEDIA OUTLET OR NOAA WEATHER RADIO.
