Strong to severe thunderstorms could move through East Tennessee this evening, according to the National Weather Service.
It’s not clear yet if the storms will affect tonight’s Oak Ridge High School graduation ceremony, which could be delayed until Friday evening if the weather is bad.
The storms are expected to develop over the western Tennessee River Valley this afternoon and then move east this evening.
The Weather Service says the storms are the result of a warm front moving north into the Ohio River Valley, creating a warm and unstable air mass over the Tennessee River Valley.
More information will be provided as it becomes available.
