National Weather Service issued an excessive heat warning for much of the Mid-South.

According to NWS, high temperatures in the mid-to-upper 90s, combined with high humidity, will produce heat index readings over 110 degrees in some areas and above 105 degrees in others.

In Arkansas:

Craighead, Poinsett, Mississippi, Cross, Crittenden, St. Francis, Lee and Phillips Counties.

In Mississippi:

Tunica, Coahoma, DeSoto, Tate, Quitman, Panola, Benton, Alcorn, Tippah, Tishomingo, Prentiss, Union, Pontotoc, Lee, Itawamba, Calhoun, Chickasaw, Monroe and Tallahatchie Counties.

In Tennessee:

Tipton, Obion, Weakley, Henry, Gibson, Carroll, Benton, Haywood, Crockett, Madison, Chester, Henderson, Decatur, Hardeman, McNairy, Hardin, and Shelby Counties.

Overnight lows will only drop to the middle 70s or lower 80s.  That means those without air conditioning will receive little relief from the high temperatures.

The heat index will be highest between 11 a.m. and 8 p.m. Wednesday.  Please try to stay in an air-conditioned area during this time of the day and drink plenty of fluids. Check up on relatives and neighbors who may not be able to care for themselves.

NWS said those who do not take proper precautions risk heat-related illnesses such as heat exhaustion and heat stroke.

The warning will expire on Wednesday at 7 p.m. for counties west of the Mississippi River and 8 p.m. for counties east of the river. After that time, cooler temperatures will move into the Mid-South for the rest of the week.
