Special update issued Tuesday, August 11, 2026

In one of my previous posts, I mentioned that storms could develop west of the main complex of storms moving southeast from KY. That has certainly happened. Thankfully, these storms are below severe limits and may stay sub-severe. Regardless, they have frequent lightning, gusty winds, and very heavy downpours of rain. These storms will continue to moving southward over the next few hours. You can easily see the lightning flashes in tonight’s sky!

So, while the main complex of storms, the ones carrying the greatest severe threat, have pushed into East TN, these new storms developing to the west of those are what will likely impact the plateau between now and midnight. Those of you in northern Fentress County are already dealing with these. Additional storms have fired off south of Interstate 40 . Radar has gotten very busy over the past hour!

The only change I’ve made to this morning’s hourly graphic is to increase storm chances from 50% to 70% around midnight.

It continues to look as though straight-line winds will be the main threat with any severe storm. However, we can never dismiss the flash flood risk when it’s this humid outside.

Other important weather information will be shared when needed. This includes additional severe weather information, model data, drought info, hurricane info, and more. Some of these can be found as tabs to this page at any time.

Special update issued Tuesday, August 11, 2026

The Storm Prediction Center has now issued a severe t-storm watch until 1:00 a.m. CDT for Morgan and Scott counties. Roane County is also included in this watch. The concern is for the storms dropping down from Kentucky. You folks in Pickett County also need to pay attention to these storms, even though you’re not in the watch.

I’m still not 100% convinced that Cumberland and Fentress are out of the woods but it is looking better for us. I’ll keep an eye on things.

The watch includes all counties shaded in purple. Notice how intense those storms are.

Special update issued Tuesday, August 11, 2026 at 6:40 pm

It has been interesting watching the radar and following the thoughts of the Storm Prediction Center this evening. There are numerous storms in Kentucky associated with a complex of storms that has been ongoing for many hours. This is the complex that I had been worried about skirting the northern areas of the plateau (along and north of a line from Livingston to Jamestown to Oneida). It now looks like the complex will be impacting areas just to the east of us, with those of you in Oneida still not being out of the woods.

The SPC has issued severe t-storm watches for southeast Kentucky and again for areas east of Knoxville. They considered a watch for portions of the plateau but they’re beginning to think the bulk of the threat will stay east of Cumberland and Fentress counties.

In an environment like ours…so hot and humid…storms may start developing westward. There are no clear indications of that just yet, but it’s something I’ve seen happen in the past.

So, for now, the closest severe t-storm watches are just across the border in Kentucky. If they extend those I’ll let you know. I’ll also let you know if there’s something that looks concerning to me, regardless of what the SPC does.

You all take care. I’ll issue another update at 10:00 pm. I’ll issue one sooner if needed. I’m keeping an eye on things!

Radar has been very active in Kentucky this evening! Storms are sliding southeast and still may skirt northern areas of the plateau.
