Heat Wave Moving East, Intensifying Week Of 6/19-25; Low 100s In GA, SC, NC, AL, TN

[hatrack]

The signs are growing that there could be a significant heat wave across the South, Southeast and Mid-Atlantic next week, with tropical humidity and highs 10 to 20 degrees Fahrenheit above average. Records may be in jeopardy in a number of major U.S. cities, with highs well into the lower 100s across Georgia and the Carolinas, for instance.

EDIT

The next big pulse of heat will be established Tuesday of next week and will really dominate from Wednesday onward. According to a plot produced by Tomer Burg, a graduate student in atmospheric sciences at the University of Oklahoma, temperatures at the 850 millibar level — roughly a mile up — will reach top-tier records in the skies over Alabama, Georgia and South Carolina. When it’s hot in the sky, it’s even toastier at the surface. That indicates decent chances of triple-digit heat. “High temperatures alone (but more certainly heat indexes) Wednesday, Thursday, and Friday could necessitate Heat Advisories across portions of the area,” wrote the National Weather Service office in Peachtree City, Ga. The combination of highs pushing 100 degrees and Gulf humidity will make for heat indexes potentially nearing 110 degrees.

As for actual air temperatures, Atlanta is looking at a forecast of 98 degrees on Tuesday and 100 on Wednesday and Thursday. Macon could see highs around 102 or 103 degrees. In Macon, the temperatures could beat records of 101 degrees set in 1925 and 1988 on Wednesday and Thursday, respectively. Atlanta will likely topple daily records that have stood since World War II. Nashville is predicted to see a high of 101 degrees on Tuesday and Wednesday — both likely topping records from 1988 — and a high of 100 degrees Thursday, which may fall a degree short of tying a record.

The temperature in Birmingham, Ala., will be around 100 on Tuesday and 102 on Wednesday and Thursday, readings that will be within a degree or two of daily records. Most of the remainder of the South, including South Carolina, Mississippi, Texas and interior Louisiana, will be around 100 degrees for three or more days in a row. Houston is likely to hit 100 degrees during the spell, and overnight lows in some places, like Dallas, might not dip below 81 at night.
