A Dangerous Heat Wave Is Coming to Parts of the U.S. — Here’s What to Expect
A prolonged period of dangerous heat is expected to continue across parts of the southern United States in the coming days, with forecasters warning that some areas could experience unusually high temperatures and oppressive humidity.
According to the latest outlook from NOAA’s Climate Prediction Center, a major and long-lasting heat event is expected across portions of the south-central United States and the Southeast, with the risk continuing into the following week.
Which Areas Could Be Affected?
The greatest concern is focused on parts of the Southern Plains, the Mississippi Valley, and the Southeast.
States that could experience significant heat include areas of:
– Texas
– Oklahoma
– Kansas
– Missouri
– Arkansas
– Louisiana
– Mississippi
– Alabama
– Georgia
– Tennessee
– Florida
The exact temperatures will vary from one location to another, but the combination of high temperatures and humidity could make conditions feel considerably hotter.
The Heat Could Last for Several Days
What makes this situation particularly concerning is its expected duration.
Rather than being a single extremely hot afternoon, forecasters are watching for a persistent weather pattern that could keep temperatures above normal for an extended period.

NOAA’s latest hazard outlook describes the potential for a major, long-duration extreme heat event across parts of the South and Southeast.
Heat Index Could Become Dangerous
High humidity can make extreme heat even more dangerous.
The heat index combines the actual air temperature with humidity to estimate how hot conditions may feel to the human body.
In parts of the Southern U.S., forecasts indicate that heat-index values could reach 105°F to above 110°F, equivalent to roughly 41°C to 43°C.
These conditions can increase the risk of heat exhaustion and heatstroke, particularly for people who spend long periods outdoors.
Who Should Be Especially Careful?
Extreme heat can affect anyone, but some people are more vulnerable than others.
