Record-breaking heat will have a firm grip on the southeastern and south-central United States into Monday.

Monday will bring another day of temperatures approaching or exceeding the 90-degree Fahrenheit mark from Raleigh, North Carolina, to Atlanta; Memphis, Tennessee; Little Rock, Arkansas; Wichita, Kansas; and El Paso, Texas.

Similar temperatures are also anticipated northward to St. Louis and Indianapolis.

Record highs will be in jeopardy in many of these communities.

The warmest locations, relative to average, will stretch from the south-central Plains to southern portions of the Ohio Valley and mid-Atlantic.

The heat may come as a shock to many people, since April generally featured temperatures well below average.

"This first prolonged stretch of heat will raise the risk of heat exhaustion and heatstroke, especially since people have not yet had much of a chance to acclimate to the heat," AccuWeather Meteorologist Ryan Adamson warned.

"In addition, the air quality will deteriorate and make prolonged outdoor activities dangerous, especially for sensitive groups," Adamson said.

For those in the southern United States with outdoor plans, remember to drink plenty of fluids to remain hydrated and minimize the risk of heat-related illness.

Seek shelter in the shade or move indoors to an air-conditioned building if you feel dehydrated, light-headed or nauseous, as these can be early warning signs of heat exhaustion or heatstroke.

Cooling demands will skyrocket before the heat, and residents should prepare to crank up the air conditioning as the combination of heat and high humidity lead to AccuWeather RealFeelĀ® Temperatures in the middle to upper 90s F across a large area.

The good news is that relief is on the way.

"Downpours spreading northward across Florida to start this week will track of more of the Southeast, Ohio Valley and back to the south-central Plains Tuesday into Wednesday," AccuWeather Senior Meteorologist Kristina Pydynowski said.

"As thunderstorms work to trim the heat during the new work, concerns for residents will shift to lightning dangers," Pydynowski said. "Higher humidity will also remain, which will put a strain on those partaking in strenuous outdoor activities."

As temperatures are trimmed to the north and east, heat will intensify across central and southern Texas starting at midweek.
