Severe Weather and Heat Threatens Mid-Atlantic and Southwest | 08-27 to 08-29
Updated Thu Aug 27th 2026, 7:21am PDT

The remainder of the week brings some active weather, so let's dive in. Today, Mid-Atlantic and Northeast areas will need to stay alert for heavy rains and thunderstorms that could lead to flash flooding. We might even see some severe storms with lightning, hail, isolated tornadoes, and strong winds. In the South-Central U.S. and Southwest, watch out for dangerous heat, with temperatures soaring into the triple digits. Stay safe and prepared if you're in these areas!

Mid-Atlantic and Northeast: On Thursday, expect a soggy day with heavy rain across Pittsburgh,PA, Richmond,VA, and Baltimore,MD. There's a risk of flash flooding and potentially severe thunderstorms that could bring lightning, hail, and even isolated tornadoes. By Friday, the cold front will move offshore, but a trailing front will keep rain in the mix, especially in New York City,NY and Philadelphia,PA. Keep your umbrellas handy!

Southeast and Lower Mississippi Valley: The rain threat extends through Atlanta,GA and Jackson,MS on Thursday, where flash flooding is a concern. The slow-moving front will stall, leading to more showers and storms on Friday. Stay vigilant if you're in these regions.

Central and Southern Plains: Showers and thunderstorms will pop up on Thursday in places like Dallas,TX and Oklahoma City,OK. These storms could cluster, increasing the risk of flash flooding. By Friday, the action shifts northward toward the Kansas City,MO area, so keep an eye on the sky.

Southwest and Rockies: Dangerous heat continues to grip the Phoenix,AZ and Las Vegas,NV areas through Friday. Temperatures will hit the 100s, with some spots reaching between 100-115 degrees. Monsoon storms could develop, especially over burn scars and urban areas in the Great Basin and Rockies.

Pacific Northwest: Cooler temps are headed your way, with a new cold front bringing showers over the Seattle,WA area. Relief from the heat is on the horizon!
