Heat wave expected to break records across the Southern United States this week
A persistent high-pressure system is driving triple-digit temperatures and high humidity from Texas to the Carolinas, with heat alerts issued for much of the region through early next week.
A high-pressure ridge is keeping a heat wave in place over the Southern United States, producing temperatures in the low 90s to low 100s and heat indices above 105 in parts of Georgia, South Carolina, the Florida Panhandle and the Memphis area. The National Weather Service has issued a range of heat advisories and extreme heat warnings, urging residents to take precautions against heat-related illness.
Nighttime temperatures are expected to remain elevated, with lows in the mid-70s to low 80s in many metropolitan areas, limiting relief after sunset. The pattern is forecast to persist through at least early next week for most of the South, while Kentucky, Tennessee and the southern Appalachians may see modest cooling.
Officials note that heat is the leading weather-related cause of death in the United States. They advise checking on vulnerable individuals, limiting outdoor activity during peak heat, staying hydrated, and using air conditioning when possible.
