We have a few heavy thunderstorms around, but most of the Tennessee Valley has been dry this afternoon and will stay dry this evening. Some dry air infiltrating from the north has helped to limit the coverage of the storms for us today. The few of us who are found by a thunderstorm can experience blindingly heavy rainfall, frequent cloud-to-ground lightning, and 30 mph wind gusts. The handful of showers around will clear out by 7 PM. The rest of tonight will be dry and mostly cloudy. Areas of fog can develop and reduce visibility in spots for the morning drive.
A few showers and thunderstorms are possible Friday. They likely will not be any more numerous than they were on Thursday. That means most of us across the Tennessee Valley will miss the showers, but a few stray showers will be around. Keep the umbrella close because all of the Tennessee Valley is fair game, though most of the Valley will stay dry. The few showers that form can bring heavy rain and frequent lightning.
Saturday will be a repeat of Friday as far as weather goes. That means we will be mostly dry with a few showers and thunderstorms. Increasing showers and thunderstorms will being on Sunday. Scattered showers and thunderstorms will be possible starting Sunday and lasting through next week.
