Light rain arrived mid-afternoon, on time, mostly south of I-40. From NWS-Nashville:
Expect most of the measurable rain to be south of I-40, with perhaps a hundredth or two falling in the Nashville area . . .
First, this happened today. Apologies to anyone who read all 100,000 of these.

Heavy rain is ending, but it’s not over. Most areas along and north of I-40 got 2″ to 3″.
2" to 3" of rain estimated by radar last 12 hours along and north of I-40. Rain slacking off now. Blue arrows depict approach of a cold front. It's 67° now at BNA, expecting upper 50°s before/around dark with arrival of Jerk North Wind. pic.twitter.com/jgz9kJ14So
Rain hasn’t been terribly heavy today. As of 3:12 pm, radar estimates most of us have received under a 1/2 inch . Blue indicates 1/2 to 1 inch. That doesn’t include many of us…just Joeltinians/Joeltonites. Someone fill us in on what you’re called if you’re from Joelton. We shouldn’t have started guessing, but since we’re here, help.
Overnight lows in the mid 50s.
Latest HRRR shows rain starting about 9 PM. Rain showers on and off all night with warm front lifting through the Midstate.
Rain off and on all afternoon/early evening. Winds coming from the south sustained at 10 MPH, gusting stronger than that at times (near 20 MPH). Winning the toss key. Temps mid/upper 60s. Birds hate this weather.
Mostly clear skies can be found statewide. We should remain mostly cloudless throughout the day before an upper level pulse scatters showers our way this evening.
Some scattered showers will quickly push through late tonight. Greater chances can be found to the north, decreasing as you go south.
It’s going to get cold overnight into the morning.
Ditch the t-shirt. Gonna be cold tomorrow morning!
We’ll only warm to 64° Friday afternoon.
Extended HRRR model run (18z) shows it:
Temps dropped overnight with cold front passage. The front also scoured out summertime humidity.
BNA recorded the drop:
In 12 hours the temp dropped 15° (74° to 59°) and the dewpoint dropped 19° (71° to 52°). #ColdFront #GoodbyeSummer pic.twitter.com/9ESIhcN9Tg
Tonight’s rush hour is greeted by a broken line of inconveniently timed downpours. A summer-ending cold front is the cause. Cooler and much drier air spills in here around and after midnight.
This is the last day of our summer airmass. Goodbye muggy dewpoints (near 70°)! With clouds, our high temp will only hit 84°.
Here’s the map at 6 AM. Notice all the warm air. But look to the left (west). That’s a cold front and it’s moving east.
