Enhanced Risk of severe thunderstorms issued for northern Texas into lower Mississippi Valley
Severe thunderstorms and heavy rainfall are forecast across parts of northern Texas into the lower Mississippi and Tennessee Valleys on April 28, 2026, with an Enhanced Risk issued for parts of the region. Very large hail, damaging winds, and a few tornadoes are to be expected, while repeated storm activity may increase the risk of flash flooding.

Multiple rounds of strong to severe thunderstorms are forecast to develop from Texas into the Tennessee Valley through April 28 as a slow-moving frontal boundary remains positioned across the region.
The Storm Prediction Center (SPC) has placed parts of northern Texas into the lower Mississippi Valley under an Enhanced Risk (level 3 of 5), with severe storms capable of producing significant impacts being forecast across the region.
The first batch of thunderstorms is forecast to develop during the morning hours over Texas and move eastward into the Mississippi Valley, bringing severe hail, damaging wind gusts, and periods of heavy rainfall as storms consolidate into a larger system.
A second, more intense round is forecast later in the afternoon and evening as surface heating strengthens instability.
The storms may repeatedly track across the same corridor, raising the risk of localized flash flooding where rainfall accumulates over short periods.
By April 29, the frontal boundary is forecast to shift southward toward the Gulf Coast, where storm activity is expected to decrease and both severe weather and excessive rainfall risks are reduced to Marginal levels. Farther north, the advancing segment of the front may trigger thunderstorms across parts of the Ohio Valley and Northeast, where isolated severe wind gusts and a brief tornado remain possible.
The pattern is expected to persist into April 30 as the front stalls over Texas and interacts with an upper-level disturbance, maintaining unsettled conditions across parts of the southern Plains and Southwest with additional thunderstorm development possible.
