UPPER LEVEL HIGH PRESSURE WILL STRENGTHEN OVER NORTH TEXAS SUNDAY AND BRING THE HOTTEST TEMPERATURES SO FAR THIS SUMMER TO THE REGION. HIGH TEMPERATURES ON SUNDAY ACROSS NORTH TEXAS ARE EXPECTED TO RANGE BETWEEN 100 AND 105 DEGREES. HIGHS ON MONDAY WILL ONLY BE A DEGREE OR TWO COOLER. FORTUNATELY SOUTHWEST WINDS WILL BRING DRIER AIR INTO THE REGION AND RELATIVE HUMIDITY WILL DROP BELOW 30 PERCENT DURING THE AFTERNOON HOURS. THEREFORE HEAT INDEX VALUES WILL NOT BE MUCH HIGHER THAN THE ACTUAL AIR TEMPERATURES. THE UPPER LEVEL HIGH WILL BEGIN TO WEAKEN SLIGHTLY BY TUESDAY WITH HIGH TEMPERATURES COOLING SLIGHTLY...BUT STILL NEAR 100 DEGREES THROUGH THE REMAINDER OF NEXT WEEK.
PERSONS INVOLVED IN VIGOROUS OUTDOOR ACTIVITIES ARE URGED TO TAKE FREQUENT BREAKS AND DRINK PLENTY OF WATER. WEAR LOOSE FITTING AND LIGHT COLORED CLOTHING. BE SURE TO CHECK ON PERSONS WITH HEALTH PROBLEMS AND THE ELDERLY...AS THEY ARE THE MOST SUSCEPTIBLE TO HEAT EXHAUSTION AND HEAT STROKE. NEVER LEAVE YOUNG CHILDREN OR PETS IN AN ENCLOSED VEHICLE...EVEN FOR A SHORT TIME...AS TEMPERATURES CAN QUICKLY RISE TO LIFE THREATENING LEVELS.
