NASHVILLE, Tenn. (AP) -- The storm system that brought devastation to central Oklahoma is expected to weaken before moving into Tennessee.
The National Weather Service updated its guidance to include all but the mountains of East Tennessee in an area that has a slight risk of severe thunderstorms through Wednesday morning.
Meteorologist Brittney Coleman with the NWS office in Nashville said high wind and hail are the major threats with the storm system. The slight probability of severe storms was extended Tuesday through the Tennessee River Valley.
NWS forecaster John Sirmon in the Memphis office said rain falling Tuesday morning in West Tennessee would help ensure the approaching heavier line of thunderstorms doesn't run into unstable air. The line is expected to move across the Mississippi River between 3 p.m. and 6 p.m. Tuesday.
