Update: Showers and storms, some severe, are moving across the area. If you have any storm reports, please tweet #tSpotter with your messages and pictures.
What’s new besides that? Not too much. Keeping it simple with temperatures falling through the 80s by mid-evening. The rain valve *should* shut off by 7 or 8pm at the very latest.

It appears rain activity will fizzle in coverage, but not in totality. A few storms could linger into the evening, mainly west of the area. Still, have the rain gear on hand for any plans you have outdoors tonight.
Temperatures will cool through the upper 80s and upper 70s by 9PM.
Saturday will repeat today, except now the better rain chances shift towards I-65 and east towards the Cumberland Plateau. It won’t be a washout, but if you have sports or other outdoor excursions planned, you’ll be wise to take the umbrella with you.
Temperatures will top out in the middle 90s with heat index readings above 100º. This heat could be dangerous. Remember, the heat index is a measure of what it feels like in the shade. Those in the sun will experience more heat than suggested by the Heat Index. Stay hydrated!
Low to middle 90s for highs, PM storm chances daily, and we’re closely monitoring the tropics for any development that *could* impact our weather later in the week. More on that below…
There’s a very unorganized tropical disturbance located in the circle:
It is not named, and therefore is not a “classified” tropical depression, storm, or hurricane. It is simply a small “eddy” (miniature circulation) entering the Bahamas, that, if convection trends up, could intensify.
Here it is on satellite:
It does this “pulsing” type of thing…where it looks really disorganized one moment, then storms fire up and it looks healthy again. This morning, it’s going through one of these cycles.
So if this “99L” is way far away from us, why talk about it? NWS Nashville sees it worthy of discussion:
We are still watching the tropics to see what the area of interest near Cuba will do over the next several days. The Euro keeps the system rather weak and takes it up the west coast of FL and then swings it northeast. The GFS has a rather creative solution keeping the disturbance weak and making initial landfall near the AL/MS coastline before drifting east along the Gulf Coast and strengthening. Either solution would not impact our weather here in Middle TN. The Euro has been more consistent with the track over the last couple of days, but looking at spaghetti plots a couple of models want to bring it into the Gulf Coast. It will be worth keeping an eye on regardless.

Through most of today, we have won the lottery of avoiding most of the pop-up shower activity. Showers have popped up throughout the region and are moving very slowly if at all. I’d keep an eye on these through the remainder of the afternoon and into the early evening hours.
Current Radar
So far so good through the day as those showers have stayed out of our area. We still have that very small chance of a shower trying to develop, but it doesn’t look too promising as the day progresses.
Current Radar
Update: Showers are quickly pushing east towards middle Tennessee this afternoon. These will continue their trek, while also diminishing as we approach dark. We will level off in the upper 70s by mid-evening and remain dry for the rest of the night. South-southeast winds will usher in more moisture overnight, along with warmer air, setting the stage for a warm/hot Wednesday.
Current Radar
The rest of the afternoon into the evening will remain pleasant for the Nashville area. Current satellite imagery shows a few clouds around the region, with the majority still sticking to our South.
It showed up today, sweeping away the humid air that’s been hanging around for weeks.
Water vapor imagery shows humid air in white (departing), dry air in black (arriving):
If you pay close attention to the above, you’ll see the humid air sink south of the TN/MS border, then surge back north of it. Although that’s disconcerting, we are confident our drying out trend will continue tonight, tomorrow, and Tuesday.
Several weeks we’ve been waiting for this. Waiting for an honest cold front, strong enough to scour away the rain and the humidity.
The cold front gets here today.
This morning’s heavy rain was pre-frontal, meaning, it’s the rain before the cold front comes through.
Current Radar
Afternoon storms are expected to continue through the late evening hours.
HRRR-p model thinks we'll see another wave of rain (maybe even storms) around 9-10 PM. Wet night likely, campers. pic.twitter.com/MsJsU9Y4wg
Current Radar
With the loss of daytime heating, rain chances will go down cooperatively. As long as we stay dry, tonight will be a beautiful night with temperatures in the upper 70s to low 80s.
