The National Weather Service's Storm Prediction Center has issued a Severe Thunderstorm Watch for southeast Nebraska, northeast Kansas, and southern Iowa as a stalled front is expected to trigger additional storm development and the threat of large hail, isolated wind damage, and a brief tornado over the next few hours.

Why it matters

Severe thunderstorms can pose a significant risk to public safety, property, and infrastructure, making it critical for residents in the affected areas to closely monitor weather conditions and be prepared to take shelter if warnings are issued.

The details

The Storm Prediction Center's Mesoscale Discussion 0441 indicates that thunderstorms developed rapidly along a stalled front in the past hour, aided by low-level warm advection. The front is expected to remain nearly stationary over the next few hours, providing a focus for additional storm development, particularly in eastern Iowa. The storms will likely pose a threat for large hail with the initial updrafts, as well as isolated wind damage as storm coverage increases and small bowing segments become possible along the boundary. There is also a risk of a brief tornado, especially where bowing segments interact with the front.

• The Severe Thunderstorm Watch is valid from 12:36 AM CDT to 1:00 AM CDT on Wednesday, April 15, 2026.
• The severe weather threat is expected to continue for the next couple of hours, with the severe threat gradually waning close to the watch expiration time.

What’s next

Residents in the affected areas should continue to monitor weather conditions and be prepared to take shelter if severe thunderstorm warnings are issued. The Storm Prediction Center will provide updates on the evolving situation as the storms move through the region.
