The " dome of heat" over the South has already baked Louisiana and much of the South, and it's going to get worse, forecasters say.
The Climate Prediction Center predicts above-normal temperatures for at least the next three to four weeks, and even through September, the average temperature is expected to be higher than normal in much of Louisiana, the Times-Picayune reports.
"It does not mean that every single day will be above normal, but it means on average over the course of the next few months above normal seems like the more likely forecast on any given day," says a meteorologist with the National Weather Service's Slidell Office.
New Orleans has already experienced eight days of hazardous heat, and nightly temperatures have been above 80 degrees.
The heat is being caused by a "massive high pressure bubble hovering in the area," the meteorologist says.
"When you have high pressure over the top of you, the air sinks, and when that happens, it compresses the atmosphere," he adds.
Unable to escape, the heat can get stuck recirculating in the area as the sun continues to beat down.
