HEAT ADVISORY IN EFFECT THROUGH FRIDAY. THE NATIONAL WEATHER SERVICE OFFICE IN TULSA SAYS THE COMBINATION OF VERY HOT TEMPERATURES AND HIGH RELATIVE HUMIDITY WILL CONTINUE TO CREATE DANGEROUS CONDITIONS THROUGH FRIDAY ACROSS MUCH OF NORTHEAST OKLAHOMA.

AFTERNOON HIGH TEMPERATURES WILL REACH BETWEEN 98 AND 103 DEGREES WITH HEAT INDEX VALUES BETWEEN 110 AND 115. OVERNIGHT TEMPERATURES WILL ONLY BRIEFLY DROP TO AROUND OR SLIGHTLY BELOW 80 DEGREES PROVIDING LITTLE RELIEF FROM THE HEAT. THE UPPER LEVEL HIGH PRESSURE SYSTEM RESPONSIBLE FOR THE HEAT IS FORECAST BY COMPUTER MODELS TO REMAIN NEARLY STATIONARY ACROSS OKLAHOMA. THUS THE HOT AND HUMID WEATHER IS EXPECTED TO CONTINUE THROUGH THE REST OF WEEK AND INTO THE WEEKEND.

THE HEAT INDEX IS A MEASURE OF HOW HOT IT FEELS WHEN THE AFFECTS OF HUMIDITY ARE COMBINED WITH THE TEMPERATURE. A HEAT INDEX OF 105 DEGREES IS CONSIDERED THE LEVEL WHERE MANY PEOPLE BEGIN TO EXPERIENCE EXTREME DISCOMFORT OR PHYSICAL STRESS. THE HEAT INDEX IS MEASURED UNDER SHADY CONDITIONS AND DIRECT EXPOSURE TO SUNLIGHT CAN INCREASE THE HEAT INDEX AS MUCH AS 15 DEGREES. CHILDREN, THE ELDERLY, AND PEOPLE WITH CHRONIC AILMENTS ARE USUALLY THE FIRST TO SUFFER FROM THE HEAT. HEAT EXHAUSTION, HEAT CRAMPS, OR IN EXTREME CASES, HEAT STROKE MAY RESULT FROM PROLONGED EXPOSURE TO THESE CONDITIONS. FRIENDS, RELATIVES, OR NEIGHBORS SHOULD CHECK ON
PEOPLE AT RISK.
