Following record-breaking heat only days ago, residents of the southern United States will face a period of chillier weather.

"Temperatures which have been averaging 10 to 15 degrees Fahrenheit above normal for the first week of November will be replaced with below-normal temperatures through the upcoming weekend," AccuWeather Meteorologist Brett Rathbun said.

Daily high temperatures were broken across the Southeast last week and this past weekend as heat and humidity settled over the region.

Summerlike heat baked areas from the Rio Grande Valley in Texas through the Mississippi Valley and Georgia, where thermometers soared unseasonably into the upper 80s and 90s.

Last week in Shreveport, Louisiana, heat records were broken four days in a row.

After falling to near-average levels on Tuesday, temperatures are expected to plummet up to 15 degrees below normal on Wednesday, failing to rise out of the 50s.

"In addition to grabbing jackets, residents of the South will also need to keep umbrellas handy as the cooler air returns," AccuWeather Senior Meteorologist Kristina Pydynowski said.

Accompanied by overcast conditions and periods of rain, Wednesday will feel especially raw throughout Texas and the Mississippi Valley.

Temperatures will rebound closer to average on Thursday as this wet weather and accompanying temperature deficit shift into the Southeast.

After reaching towards 80 F on Monday and Tuesday, Atlanta will fail to see the 70s again this week.

Temperatures are expected to fall even further in the South when another shot of cool air sinks through the country later this week.
