The oppressive heat that has settled over southeast Arkansas in recent days will give way to cooler temperatures, but not before another 24 hours of extreme highs.

Steamy weather is expected across much of the state again on Thursday, with highs in the mid to upper 90s and heat index values of 100 to 110 degrees, according to the National Weather Service.

Thursday night into Friday, a cold front and accompanying showers and thunderstorms will move into the state. While widespread severe storms are not expected, a few strong storms with strong winds could occur.

The front will also usher in much cooler temperatures. Friday's high is expected to reach just 91 degrees, while Saturday and Sunday's highs will be a much more comfortable 88 degrees, according to the NWS.

A heat advisory has been issued for much of Arkansas on Thursday. 

A heat advisory means that a period of hot temperatures is expected. The combination of hot temperatures and high humidity will combine to create a situation in which heat illnesses are possible. The NWS offers the following tips to deal with extreme heat conditions:

Drink plenty of fluids...stay in an air-conditioned room...stay out of the sun...and check up on relatives and neighbors. Take extra precautions...if you work or spend time outside. When possible...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...call 9 1 1.
