Hot and humid conditions will remain entrenched across the south-central and southeastern United States into midweek.
High temperatures are expected to exceed 90 degrees Fahrenheit on multiple days from Texas and Oklahoma eastward to Arkansas, Tennessee, Alabama and Georiga into Wednesday.
A few areas could reach or exceed the century mark, especially across parts of Texas and Oklahoma towards the middle part of the week.
The heat could build to the highest levels of the year so far in some locations across the South this week.
Cities that can expect their hottest day of the year so far include Dallas and San Antonio; Little Rock, Arkansas; Columbia, South Carolina; and Raleigh, North Carolina.
Increasing humidity levels will make the heat even more stifling.
The combination of heat, humidity, sunshine and other factors will push AccuWeather RealFeel® Temperatures past 100 in some places, even if the actual high stays in the 90s F.
The heat could be dangerous for those who are outside for a prolonged period of time.
"When temperatures are near or above 100 with moderate humidity, it is extremely dangerous to be outdoors for a prolonged period of time," AccuWeather Meteorologist Michael Doll stated.
People who work outdoors should remain aware of signs of heat-related illnesses in themselves and/or co-workers.
"The risk for heat stroke and heat exhaustion will increase with RealFeel® Temperatures exceeding 100," Doll warned.
Plenty of water or other non-alcoholic beverages will be needed in order to prevent dehydration.
Residents are reminded to never leave children or pets inside of a parked car, as the temperature inside the vehicle can reach a deadly level in mere minutes.
Those seeking relief from the oppressive conditions at local lakes or pools should keep an eye on the sky as a few thunderstorms could erupt during the heat of the day.
Shelter should be sought inside a building or car at the first sight of lightning or rumble of thunder.
