Published on Mar. 9, 2026

A strong cold front is expected to move through the Dayton, Ohio area on Wednesday, bringing the potential for strong to severe thunderstorms. The First Warning Weather Team has issued a Code Red Weather Alert due to the threat of damaging wind gusts and an isolated tornado risk. Localized flooding is also possible due to heavy rainfall.

Why it matters

Severe weather can pose a significant threat to public safety, property, and infrastructure. The Dayton region is no stranger to powerful storms, and residents will need to remain vigilant and prepared for the potential impacts.

The details

The strongest storms are expected to arrive late Tuesday night into Wednesday morning, with the greatest risk for severe weather along and south of Interstate 70. Damaging wind gusts will be the primary concern, but there is also a small threat for an isolated tornado. Heavy rainfall could also lead to localized flooding issues.

  • Overnight Tuesday into Wednesday morning, a strong low pressure system moves into the Miami Valley increasing the risk for strong to severe storms.
  • The highest threat for severe storms is mainly to the west Tuesday night, but the greater local risk arrives by late morning and into the early afternoon along the front.
