EXPECTED ALSO TO BE HIGH ENOUGH DURING THE AFTERNOON HOURS...
A HEAT ADVISORY WILL BE ISSUED COVERING MOST LOCATIONS WEST OF
THE CUMBERLAND PLATEAU REGION. THE DECISION TO ISSUE THIS HEAT

OTHERWISE...MIDDLE TENNESSEE CAN STILL EXPECT TO EXPERIENCE HOT
AND HUMID WEATHER CONDITIONS THROUGH AT LEAST NEXT WEDNESDAY.
HIGH TEMPERATURES ACROSS MIDDLE TENNESSEE...EXCEPT THE CUMBERLAND
PLATEAU REGION...ARE EXPECTED TO BE PRIMARILY IN THE MID 90'S EACH
DAY. ACROSS THE WESTERN TWO THIRDS OF THE MID STATE...HEAT
INDICES WILL BE AVERAGING BETWEEN 100 TO 104 DEGREES...WITH SOME
ISOLATED SPOTS REACHING AND EVEN EXCEEDING 105 DEGREES FOR SHORT
PERIODS OF TIME.
