July-like heat, humidity to persist across part of South this week

Brandon Buckingham

Temperatures across much of the Deep South and southern Plains this September have felt more like July as a ridge of high pressure has been stagnant for the majority of the month.

Some temporary relief is coming to eastern areas by midweek, but areas farther west will continue with a hot and humid late-summer weather pattern.

Multiple cities across the region have set numerous daily high temperature records, some of which have held for over 100 years.

Atlanta set daily temperature records this past Tuesday through Friday as temperatures soared into the upper 90s each afternoon. Nashville, Knoxville and Chattanooga, Tennessee; Montgomery, Alabama; as well as Macon and Columbus, Georgia, have all broken multiple daily high temperature records this past week as well.

Some of these cities will continue to challenge record temperatures through midweek as the overall weather pattern will remain relatively unchanged across the South.

"Atlanta has an average high temperature of 83 for this time of the year, and highs are forecast to rise to record-challenging readings in the middle to upper 90s again on Tuesday," AccuWeather Meteorologist Robert Richards stated.

As the dome of high pressure continues to sit overhead, many interior cities will struggle to pick up much-needed rainfall.

As of the latest U.S. Drought Monitor update last Thursday, more than 50 percent of the state of Texas is experiencing some form of drought. There are also pockets of drought scattered throughout the Southeast.

AccuWeather meteorologists are continuing to track a disturbance over the Gulf of Mexico that is expected to bring some beneficial rainfall to coastal portions of Texas and Louisiana early this week. Unfortunately, the inland extent of the rainfall will be minimal, confining drought relief primarily to coastal areas.

Progressing into midweek, a portion of the ridge of high pressure over the Southeast is expected to weaken, allowing for some relief from the mid-summerlike heat.

A northeasterly breeze across the Carolinas and Georgia will bring cooler air and lower humidity levels back into the area. Unfortunately, the reprieve will be short-lived, as the heat is expected to build back into this area by the weekend.

Meanwhile, a little farther west across the Deep South, the heat will continue its grip through the week as some areas may even have the thermometer top triple-digits. Regardless of the exact air temperature, AccuWeather RealFeel® Temperatures will exceed 100 F across a wide swath of the Deep South.

With football season underway, it is important for athletes to take necessary precautions to avoid heat-related illnesses. Taking frequent water breaks and avoiding exercise during the peak heating afternoon hours can limit the chance of falling victim to the heat.

A stagnant air mass overhead will also lead to air quality issues across much of the South, especially in urban areas and locales that do not receive any rainfall. Children and people sensitive to high levels of ozone and pollutants in the air are urged to take caution while heading outdoors.

Latest forecasts suggest that there is little, if any, relief in sight across the Deep South and Texas through this weekend as the stagnant, summerlike pattern refuses to give way to more seasonable conditions.
