Heat advisory issued from 1 p.m. through 8 p.m. as temperatures, heat indexes soar
From Staff and Wire Reports
Dry conditions and a strong area of high pressure will create record high temperatures and heat danger.
Temperatures will climb rapidly today across most of the region, with heat index values soaring above 100 to 105 degrees by this afternoon. The oppressive heat is expected to last through mid to late evening.
Hot temperatures and moderate to high humidity will combine to create a situation in which heat illnesses are possible. Take extra precautions if you work or spend time outside. Reschedule strenuous activities to early morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke. Wear light weight and loose fitting clothing when possible and drink plenty of water.
To reduce risk during outdoor work the occupational safety and health administration recommends scheduling frequent rest breaks in shaded or air conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency and you should call 911 if you believe someone has suffered from a heat stroke.
The heat wave is expected to bring record high temperatures into the weekend.
A ridge of high pressure will be over the region for the next few days. This high will help to generate near record or record high temperatures through Monday, with temperatures expected to climb to between 95 and 100 in the Tri-Cities area, to around 100 degrees in the Knoxville area, and between 100 and 105 in the Chattanooga area.
Heat index values will be slightly higher than actual high temperatures.
Readings soared into the triple digits Thursday, setting or tying records for the date in Nashville, Knoxville and the Tri-Cities.
Nashville peaked at 105 degrees, breaking a daily record set in 1952 and coming within a degree of the all-time high of 106 set on June 30 of 1952.
The high of 100 in Knoxville tied the record for June 28 and a reading of 97 in the Tri-Cities broke the record of 96 — both from 1952.
The National Weather Service said other official highs were 102 in Chattanooga and 101 in Memphis — just short of records.
