Record Heat Will Blanket U.S. South This Week, Rogers Says

Record highs will be set across the U.S. South this week and hot weather may linger through mid-August, according to Matt Rogers, president of Commodity Weather Group LLC.

His forecast calls for the heat across the eastern half of the country to retreat and center on the southeast from Aug. 7 to Aug. 16. The hottest weather is expected over northern Texas, Oklahoma and western Arkansas.

“The bigger heat story continues to be in the deep South and Texas, where records are expected to continue falling this week with more moderate to much-above-normal temperatures frequently over the next two weeks,” Rogers said today in a note to client.

Excessive heat warnings and watches, meaning the combination of high temperatures and humidity may make it feel as warm as 116 degrees Fahrenheit (47 Celsius), extend from Iowa to Texas and eastward to Tennessee, according to the National Weather Service.

A high of 107 degrees set a record in Dallas yesterday, breaking the old mark of 106 set in 1998, according to the weather service. Today’s high may reach 109 and the temperature may touch above 105 for the rest of the week.

MDA EartSat Weather predicts the high temperature in Dallas will remain above 100 until at least Aug. 11 and Houston will flirt with 100-degree highs through the same timeframe, with six of the next 10 days reaching highs of 100 degrees or more.

A daily record of 111 degrees was set in Fort Smith, Arkansas, which also extended its record for consecutive 100-degree days to 28. The prior record of 17 days was set in 1934.

The high in St. Louis is expected to be 103 degrees, 96 in Chicago, 110 in Tulsa, Oklahoma, 99 in Houston, and 100 in Memphis, according to the weather service.
