A flood advisory has been extended for the Stones River, but the good news is that the river stage level is falling:
If you run across areas like Lebanon Road, do not attempt to drive through any amount of water. Turn around, don’t drown.
Officially, Nashville received 4.47″ of rain. That is a lot. For radar estimated rainfall across the area, refer to the graphic below.
There is still one flood advisory out for Davidson County concerning the Stones River.
To start, we saw A LOT of rainfall between Friday and Saturday.

The worst of the rain/storms is gone, but…
A few active flood warnings/advisories are in effect, across the Davidson/Williamson County areas. These are attributed to heavy rainfall causing stream and river rises that could run over into low-lying areas. We’ve already seen evidence of flooding in many spots!
Current radar imagery has showers and some non-severe thunderstorms moving across the entire Middle Tennessee area. These storms, for Davidson and Williamson county so far, have been non-severe. The severe weather threat, however, is still not ruled out.
Update: The latest run of the HRRR Model isn’t picking up all too well on showers/storms currently moving into middle Tennessee, headed our way. In short, let’s keep an eye on radar as a chance for rain may increase in the next few hours. If the activity holds together, it will impact Nashville proper during the start of the PM commute (4:00-4:30PM).
Showers have begun to pop-up across the Middle Tennessee region. If you have any afternoon or early evening plans, you may want to keep the umbrella handy just in case.
Luckily, any thunderstorms we see today should be weaker than those we saw yesterday. Nonetheless, there is always the possibility of damaging winds and small hail with these afternoon thunderstorms. I will also mention that localized flooding could become an issue for areas that have already received a lot of rain this week.
GFS Model Loop Through Monday
Of course, this model run alone is not Gospel. However, an active pattern with intermixed dry periods are expected over the next 7 days.
Wednesday and Thursday will be predominantly dry with temperatures into the 80s. A frontal boundary will approach the area Friday, increasing our chances for storms. By Saturday evening, a decent amount of instability and shear will be present to set off thunderstorms along a well-formed cold front. No official concerns of severe weather are warranted yet, but this could very well change as the event approaches.
Scattered showers and some non-severe thunderstorms have begun to fire up across Middle Tennessee. These showers will continue to push through the area for the remainder of the afternoon.
While there is no severe weather expected with any thunderstorms we see, they also need to be taken serious. Frequent lightning, strong wind gusts, heavy rainfall, and even some small hail could be associated with these thunderstorms. Be sure you are not caught outside when one arrives!
Dry air set up today between us and Clarksville. As I write this, the dewpoint in Nashville is d-r-y in the upper 40°s, but it’s pretty humid in Clarksville and points northwest, where the dewpoint is over 60°:
