Heavy Rain and Storms Expected in TX to Mid-Atlantic, 10-15 to 10-17

Updated Thu Oct 15th 2026, 5:17am PDT

We're keeping an eye on a dynamic weather situation from Texas up to the Mid-Atlantic. A robust weather front is making its way through the region, promising lots of rain and possible severe storms. Moisture from the Gulf is feeding into the system, leading to potentially dangerous weather conditions, including flash flooding in these areas. The Midwest and Ohio Valley are also in the path of this front, likely seeing some severe weather action.

Thursday: Heavy Rain and Storms from Texas to Midwest

Today, a large portion of Texas is under a flood watch. We're expecting intense rainfall due to moisture coming from the Gulf. Areas already saturated from previous rain could see flash flooding, so be cautious. The Mid-Mississippi Valley and Ohio Valley might also experience severe thunderstorms, with the potential for damaging winds, hail, and even a brief tornado.

Friday: Severe Weather Moves to Mid-Atlantic

On Friday, the storm system pushes into the Mid-Atlantic region. Instability and increased wind shear may trigger severe thunderstorms. As the storm's center moves into southeastern Canada, rain and storms will extend towards the Atlantic Coast. Meanwhile, the Pacific Northwest will have periods of rain as another system moves through.

Temperature Changes Ahead

Expect a shift in temperatures over the next few days. By Thursday, cooler air will spread into the central U.S., pushing the warmth eastward. On Friday, temperatures will drop even more, with highs only reaching the 50s and 60s in many areas.
