The Tornado Watch will expire for the Newschannel 9 viewing area at 7pm…..expect general rain showers through mid evening, and most isolated storms will stay below severe limits. I will continue to monitor the radar and provide updates when necessary.

6:50pm - Fairly robust cell from the TN/GA border near Red Clay southward through Cohutta to Prater’s Mill. Very heavy rain occurring, but so far staying below severe limits. In Bradley County, north east of Clevelan from Baugh Spring to about Misty Ridge, some heavy rain is occurring…..Also, some moderate rain near Decatur moving toward Athens. Heavy rain is slowly ending from west to east.

6:05pm - Still “Warning Free”, but most areas are wet. Moderate rainfall in Marion County from Whitwell to Jasper. Signal Mountain also experiencing moderate rainfall. There has not been a lot of lightning with these cells, but some wind gusts above 35mph will be possible. The strongest cell is over central and southern Walker County from Cooper Heights to Lafayette. Brief wind gusts and heavy downpours can be expected there. This will also affect the Pigeon Mtn region as well as Chickamauga and Rock Spring.

5:25pm: Warning-Free at the moment……..The Warning for Jackson County was cancelled. This cell will continue moving northeast toward Stevenson, Bridgeport and neighboring areas of Dade (GA) and Marion (TN) County. The main elements of this cell will be heavy downpours of rain, wind gusts above 35 and frequent lightning. Elsewhere most of the cells are below severe limits. It will be a wet period for the next 2 hours. So, any outdoor plans will be put to a halt through the early evening.

4:35pm: Tornado Warning for Jackson County until 4:15pm CT……This cell is on the far southern end of Jackson County and will move northeast toward Section, Pisgah and Scottsboro. This is a radar indicated warning, meaning that the storm has the potential for tornadic development…..Elsewhere, a strong storm noted on the northeast part of Franklin County just south of Tullahoma. This cell is showing some signs of rotation meaning that it could produce some large hail and damaging wind gusts above 55mph. A line of heavy rain pushing east from western Jackson County, Al not associated with the current Warning.

3:55pm: Mostly rain with some heavier pockets locally. The strongest storms to approach our local region is lining up now from just south of McMinnville to Huntsville, AL. Western Franklin and Coffee counties can expect heavy rain and wind gusts above 35mph along with frequent lightning. Also western Jackson County, AL will have the souther edge of this line advancing into the county at 3pm CT. The strongest storms with this line are well south of our viewing area. Gadsden southward to Birmingham can expect stronger storms and potential wind damage.

3:10pm - Light to at times moderate rain is currently moving across the immediate metro area. Downtown to East Brainerd is wet and from Jasper to Coalmont also experiencing some moderate rainfall. Currently, no severe storms are over our local counties. the strongest storms are from Lewisburg, TN southward to Huntsville, AL. There was a Tornado Warning associated with the cell that moved past Lewisburg. This cell should enter western Franklin County by 3:45pm. Current temp at WTVC: 75.

    Sounds like we’re in for a VERY SEVERE evening to me.

    I hope I am very wrong?

    Looks like the TN Valley got spared once again. Those tornadic storms just died as they came this way. What in our atmosphere kept them from staying together, Mr. Glenn?

    The bad weather stay mostly south of Nashville as well (where I am). Loretto in Southern TN and Neapolis,TN we’re the only places that received damage from the storms as far as I can tell in Middle Tennessee. The low pressure center passed close enough to us that the main instability stayed to our south would be my answer Amanda.

    The air mass over our part of the Tennessee Valley was more stable than the environment to the west where the storms developed and thrived.
