Memphis, Tennessee – Triple-digit heat will push deeper into West Tennessee on Thursday, August 14, as Memphis and surrounding areas face dangerously high temperatures, with heat-related illnesses becoming a serious concern. The National Weather Service (NWS) in Memphis has issued a Heat Advisory for Thursday from 11 a.m. to 7 p.m., with heat index values expected to reach 105°F or higher. Cities under the advisory include Memphis, Clarksdale, and parts of northern Mississippi.
The extreme heat will continue throughout the weekend, with Saturday projected to bring the highest heat index values—up to 109°F in Clarksdale and 107°F in Memphis. This marks one of the most intense stretches of summer heat so far this year for the Mid-South, prompting officials to issue urgent safety advice for residents.
