Forecast Discussion
Both today and tomorrow’s severe storms chances look very low. Still, we can’t rule out an isolated strong/severe storm. This year seems to be the year of the “brief spin-up” tornado, so we’re especially leery of those these days. Thankfully, those are brief and along the lines of EF-0 intensity. I’d be surprised if we see any of those this week, but I can’t say our chances are zero for that.
The weekend continues to trend drier. That’s good if you want a nice, warm weekend!
Meteorologist Mark’s Wx Concerns
Widespread severe weather is not expected today or tomorrow, but one or two storms could become strong to briefly severe. This is the typical summertime activity that we grow accustomed to this time of year. A brief tornado spin-up is not out of the question, but the chances for that are quite slim.

Wednesday Weather 101
Derechos are the name given to long-track, long-lived wind storms that scream across parts of the country in the summer months. The peak months for these wind events are June, July and August. The map below shows the expected recurrence of these events. For our area, we can expect a derecho about once every two years or so.
Derechos can be as destructive as some landfalling hurricanes but come with much less warning. Forecasting these wind events is challenging and sometimes the actual development of the derecho is the first clue that one will occur that day. These wind events can frequently produce winds speeds in excess of 100 mph.
The radar imagery below shows what a derecho typically looks like on radar. They are basically squall lines that bow out. The folks in the apex of the bows are often experiencing the strongest wind gusts. These thunderstorm complexes can travel hundreds of miles.
Today’s Tennessee Weather
Widespread showers and storms will light up the radars across Tennessee today. A few of those storms could be strong to severe across mainly West and Middle Tennessee. Damaging winds are the main threat with any of those storms, though a brief tornado is not out of the question. Rain and storms will keep afternoon highs in the 70s statewide.
Tonight’s Tennessee Weather
Rain chances drop off overnight, but there will still be plenty of showers and thunderstorms scattered about. Overnight lows will be mild and in the 60s across the region.
Tomorrow’s Tennessee Weather
More showers and thunderstorms are likely for Thursday, though that activity shouldn’t be nearly as widespread as today’s. A few of the storms across Middle and East Tennessee could be on the stronger side, with a damaging wind gust being the main threat.
Drought Monitor
The drought monitor is updated each Thursday.

The National Weather Service in Goodland, Kansas, captured this amazing double rainbow at their office yesterday evening. They tweeted that this occurred just after a thunderstorm.
NASA Nerdology
A small piece of space debris struck part of the International Space Station last month and left a hole! As you can see, it wasn’t a very big hole. The hit was a lucky strike, so to speak, since the “arm” that was hit is only 14″ in diameter and about 58 feet long. Thankfully, operations will continue as planned.
