Widespread, severe thunderstorms will have the capability to produce strong (EF-2+), long-track tornadoes, a few violent (EF-4+) tornadoes as well as damaging wind gusts in excess of 70 MPH. Not only will we be dealing with a damaging wind threat and tornado threat, flooding will also be an issue as the Tennessee Valley already has over-saturated soils in most locations. Excessive rainfall is expected, and any wind gust will have the potential to easily knock trees and powerlines down because of this.

There will be two rounds of rain/storms to move through during the day and night today. The first round of storms started around 3 AM and will last until around 10 AM ahead of the warm front. The first round will bring the potential for a few marginally severe storms that will be capable of producing heavy rainfall/flooding and localized damaging winds.

The second round of rain/storms will occur in the afternoon and this will be the main window for severe weather that will be associated with a low pressure system and a cold front to follow. This will occur mid-afternoon (12 PM) and will last until late tomorrow night (11 PM). Damaging winds, tornadoes, heavy rain/flooding, and large hail will all be a possibility within this round of storms.

Please don't get caught up on the colored categories. A regional outbreak of severe weather is to be expected tomorrow. Have your safety plan in place before the arrival of tomorrow's storms as well as have multiple ways to receive warnings if they become issued (NOAA weather radio, smart phone, TV, etc.). Periodically check in with your local officials and broadcast meteorologists to stay up to date with the very latest.
