00:00A new heat dome is set to build across the southern U.S.
00:03The heat will first strengthen over Texas in the coming week.
00:06It is then expected to spread across the south-central states.
00:10Parts of the southeast Ohio Valley and mid-Atlantic are also affected.
00:14Temperatures could run 5 to 10 degrees above average.
00:17Highs will generally reach the upper 80s to upper 90s.
00:21Texas, Oklahoma, Louisiana, and Arkansas face the most intense heat.
00:26Some locations could reach or exceed 100 degrees Fahrenheit.
00:30Humidity and sunshine will make conditions feel even hotter.
00:33Real field temperatures could run another 5 to 10 degrees higher.
00:36Light winds may also contribute to poor air quality.
00:39The heat follows one of the hottest summers on record.
00:42In July, the lower 48 averaged 76.9 degrees Fahrenheit.
00:47That broke records dating back to 1895.
00:50Meanwhile, storms will develop around the heat dome's edges.
00:54Downpours and severe thunderstorms may affect the plains and Midwest.
00:57Some storms are also expected to reach the northeast.
01:01Forecasters are closely watching another system near the Atlantic coast.
01:05That storm could move across Florida and into the Gulf.
01:08Meteorologists say tropical development remains possible.
