There will be a risk for severe thunderstorm activity across much of the Ohio and Tennessee Valley Region on Sunday, as indicated by the latest outlook from the SPC which is shown above.
Strong to severe thunderstorms will likely be ongoing at the beginning of the day tomorrow across portions of eastern Missouri, eastern Arkansas and northern Louisiana. This activity will move Eastward throughout the day, with some reorganization and/or reintensification likely during the afternoon hours, especially within the yellow shaded area on the above image.
Damaging wind gusts and large hail are expected to be the primary threats for Sunday afternoon and evening across this region, however an isolated tornado cannot be completely ruled out.
The lower levels of the atmosphere will not be as unstable across the Ohio and Tennessee Valley region on Sunday as compared to today across the Plains. Therefore the overall risk and intensity of severe weather is expected to be somewhat lower than what we are likely to see today.
