A few scattered showers continue to move across the area. If you have early evening plans, bring the umbrella just in case.
Into the remainder of the evening, all eyes are on a few lines of showers currently located in western Tennessee. If these showers hold together, which some models think they will, we could see another round of showers and thunderstorms later tonight.
Most fireworks only fly about 1,200 feet up.
Models think “LCL levels” will be low tonight, meaning clouds should be closer to the ground. Some models predict cloud levels as low as only a thousand feet.
We’ve already seen a couple of severe thunderstorms this afternoon. As always, if you have any damage from today’s storms tweet using #tspotter to report it to our local National Weather Service Office.
A typical summertime day is expected with highs in the upper 80s and dew point temps in the low 70s. It’ll be nice and sunny to start, with diurnal heat showers possible later today.
Into this afternoon, we introduce those shower and thunderstorm chances. Latest run of the HRRR, shown below, displays what it thinks will happen today.
Warning: Weather models aren’t very good at handling summertime thunderstorms.
Summer storms are very hard to predict, but as a general rule: rain and storms are mostly likely to develop between mid/late afternoon and early evening.
There are times weather models can see what’s coming so we can provide you a good, reasonably reliable (not perfect), “when and where.”
This is not one of those times.
Weather models, which in a perfect world should arrive at the same thing, predict different things. Weather models also aren’t very good at handling summertime thunderstorms.
UPDATE as of 5:00PM CDT: The eastern half of both Davidson/Williamson remain under a “Marginal Risk” (1 out of 5) for damaging winds and some hail.
We’ve seen several showers and thunderstorms impact Davidson/Williamson counties today, some with ~40 mph wind gusts. More could develop through the evening, so we will be monitoring radar for developments.
So far today we have stayed, for the most part, rain-free. Latest radar scans do not show a whole lot on the radar, so good news so far. Into the rest of the evening, we will still need to keep an eye on showers attempting to move our way.
Update: We’ve seen a few showers and storms roll through the bi-county area today. These should dissipate in conjunction with sunset, but heavy downpours remain possible through the evening.
Friday will provide increased rain chances, but particularly Friday night into Saturday. We will need to carefully monitor the potential for strong/severe storms on Saturday. While shear values are not very impressive, instability is high enough that when combined, could produce a few misbehavers. The biggest concerns would be hail and damaging winds on Saturday. All of that being said, we are not yet under any formal severe risk.
Today appears to be our last day without those afternoon isolated shower chances. Enjoy our one last semi-bearable day.

Into this evening, clear skies will prevail. Temps will not drop as low as they have in recent times, with overnight lows only expected to reach down into the low 70s.
