Memphis, Tenn. – Dangerously high heat is set to blanket the Mid-South on Sunday, with temperatures feeling as hot as 110°F in parts of Tennessee, Arkansas, and Missouri.
The National Weather Service has issued an Extreme Heat Warning, effective from 11 a.m. to 8 p.m. CDT Sunday, urging residents to take immediate precautions against life-threatening heat conditions.
Extreme Heat Warning Issued
The warning covers multiple counties across the Missouri-Tennessee border, including West Tennessee counties such as Dyer, Madison, and Weakley, as well as Craighead and Mississippi counties in Arkansas, and Pemiscot and Dunklin counties in Missouri.
Cities like Memphis, Jackson, Jonesboro, and Blytheville are expected to experience the most intense heat during peak afternoon hours, with heat index values reaching 110°F.
Health Risks and Precautions
Under these extreme conditions, heat-related illnesses such as heat exhaustion and heat stroke can develop quickly. The National Weather Service advises residents to take the following precautions:
Stay indoors with air conditioning when possible.
Drink plenty of water to stay hydrated.
Check on vulnerable neighbors or relatives to ensure their safety.
Limit outdoor work and activities, especially between noon and 6 p.m., when the heat will be at its peak.
Record-Breaking Heat
This heat wave is expected to be one of the hottest days of the summer so far and could potentially rival the records set in July 2022. It marks the first Extreme Heat Warning for some of the affected counties this season.
The sustained heat is also a cause for concern, and additional advisories may be issued if temperatures remain elevated into the coming week.
