This afternoon: Strong storms (hail, wind)
Wednesday afternoon: Strong storms (hail, wind)
Our atmosphere remains unstable today , folks, so we’ll have to be mindful of showers and storms again today. Yesterday, the main threat of severe weather was just off to our west, though we had just as many strong/severe storms over here as any of those folks did. Today, the greater risk is over in East TN, but I think we have just as good of a chance for strong to severe storms. Like yesterday, the main threat will be hail and damaging winds. And, like yesterday, any storm that develops will likely contain frequent cloud-to-ground lightning and torrential rainfall.
Radar this morning (8:30 a.m.) is showing lots of thunderstorm activity in Kentucky that will be slipping east and southeast. Those showers/storms you see in southern Middle TN may move our way later on. Our atmosphere is in such an unstable state that we could see anything pop up at anytime.
I think tomorrow will be drier than today, but we certainly run the risk of afternoon showers and storms. Those rain chances increase once again Wednesday, when we may be dealing with more strong storms.
After Wednesday, things look to turn hot and dry.
I’ll be here keeping an eye on it all.
We were lucky again last night. Storms stayed mostly up in Kentucky and I’m sure they kept some folks up all night. WeatherTAP’s lightning detection map has been on fire all night long up there. Which brings me to my next point, please be careful if you’re outside when one of these storms pops up. These summer storms can contain some mean cloud-to-ground lightning. Yesterday we had a house struck by lightning and I saw on the news where a lady was struck and killed by lightning on a Florida beach. Be especially careful if you’re caught on the water in these storms.
Our main threats today will be large hail and damaging winds. Yesterday, we had a bit of a tornado threat, though it was still really low. That was due to an outflow boundary being draped across our area. Those boundaries can give a storm some localized rotation to to do a brief spin up. That boundary has weakened today, so we don’t have to worry much about that anymore.
Yesterday, we had a potent storm come through the Rinnie community. Jon Matthews, who lives on Bear Creek Road in Rinnie, took this video and sent it to me. We lost power for about an hour. This storm was riding that outflow boundary. Nice video, Jon! (Here’s the link in case the video doesn’t play for you https://youtu.be/WqlAkw7gpco)
Like I said, more strong storms are possible today, so stay weather-aware.
I will say this, we still need rain in some parts of the county. I know some of you have had more than enough rain, but at my house we’ve only at about 3/4″ for the whole month. Here at weatherTAP, in downtown Crossville, we’ve had only 0.98″ for the whole month. I was talking to Mark Hall in Mayland this weekend and they’ve had at least three times as much rain as I have had this month. It’s always incredible how much rainfall amounts vary across the plateau this time of year.
On this day in 1989, Tropical Storm Allison dropped very heavy rainfall across Louisiana and Texas. While that’s not anything to really write home about this time of year, it is a bit unusual in that Allison developed from Hurricane Cosme. Wait…how could an ‘A’ storm, which would have been named first, develop from a ‘C’ storm, which would have been the third storm? Well, I’m glad you ask! Cosme had been a hurricane in the Pacific Ocean, where they name their own storms. So, Cosme was the third storm over there for that season. Then, it crossed Mexico and redeveloped in the Gulf of Mexico, where we name our own storms as they develop. Now, when I say it crossed Mexico and got into the Gulf I don’t mean it crossed at the narrowest part. No, it crossed the whole dang country. What’s weird is that it didn’t completely disintegrate while covering that much terrain. It still enough spin to it to turn into Allison in the Gulf of Mexico. What a journey for that storm!
Below is Hurricane Cosme’s path.

Ever once in a while we get weird storms like this. heck, we’ve even had tropical systems strengthen after making landfall, which is really, really odd. Weather can get weird, folks, but that’s what makes it so darn cool (ha). We need a t-shirt that says, “Keep Weather Weird.” It’ll be interesting to see what this hurricane season holds. At this time, there are no tropical troubles in sight.
You all have a great day and I’ll be keeping an eye on these storms!
