Stifling, Long-Lasting Heat to Grip South Through Late-August

While heat in the South during August is common, the upcoming weather pattern may deliver some of the hottest weather of this summer.

Heat building over the South Central states will reach into parts of southern Atlantic Seaboard during the last couple of weeks of August.

A zone of high pressure is forecast to build at most levels of the atmosphere, which will gradually tone down the number of showers and thunderstorms and reduce cloud cover.

Many locations from Texas and Oklahoma to Tennessee, as well as portions of Georgia and the Carolinas also have the potential to experience their longest and most consistent stretch of heat this summer.

For example, Atlanta has had only five days in a row of 90-degree temperatures, and these occurred from June 16 to 20. Not only may Atlanta double its string of consecutive 90-degree days, but it could eclipse the season high so far of 95 F. The typical high in Atlanta during the second half of August is 88 degrees.

In addition, widespread highs in the 90s during the upcoming couple of weeks in the South, high humidity, sunshine and other factors will result in AccuWeather RealFeel® temperatures at or above 100 F for several hours most days.

Farther west in portions of Louisiana, Arkansas, Oklahoma and Texas, actual temperatures may reach 100 F on multiple days.

Portions of the South Central states have experienced a significantly cooler-than-average summer so far.

Little Rock, Arkansas, is one city in the South Central states that may not only top their highest temperature of the summer so far of 96 F but could have triple-digit heat.

Dallas has experienced close-to-average warmth this summer so far. The metro area has had 17 days of 100-degree heat this summer, as of Aug. 17, but could have more than 5 days in a row of such temperatures, which has not yet occurred this year.

Farther north, some heat will push into parts of the Northeast on occasion through the end of August. However, ongoing rounds of showers and thunderstorms, wet soil and a stubborn southward dip in steering winds will limit the heat to one- or two-day stretches.

Above-average warmth is projected for portions of the Central Plains and the Ohio Valley states during multiple days during the second half of August.
