The 2023 Ally 400 is scheduled to go green Sunday at 7 p.m. ET, though the latest NASCAR weather forecast for Nashville is a bit worrisome.
There is rain expected in Nashville throughout the day and into tonight, which has the potential to impact the Ally 400.
With this in mind, let's take a look at the latest NASCAR weather forecast for Nashville, including the chances that rain delays tonight's Cup Series race.
NASCAR Weather Forecast for Nashville
According to the National Weather Service, it's expected to be hot and wet in Nashville on Sunday.
There's currently a 70% chance of rain with high temperatures reaching 90 degrees.
The NASCAR weather forecast for Nashville doesn't get much better tonight either as there's a 60% chance of precipitation.
A quick look at the hourly breakdown shows just a 15% chance of rain at 7 p.m. ET, which is when the Ally 400 is scheduled to start.
However, that percentage of rain increases to 49% by 9 p.m. ET and 60% by 10 p.m. ET, so we could be racing to halfway tonight assuming that the track is dry enough for NASCAR to start on time.
A NASCAR Cup Series race is official once half of the scheduled laps are completed, which would be 150 laps tonight.
Should NASCAR be forced to postpone tonight's Ally 400 at Nashville due to rain, the weather forecast for Monday looks much better with lots of sun and a 0% chance of rain.
Based on the latest NASCAR odds, Martin Truex Jr. is the betting favorite at +450, followed by Ross Chastain (+550), Kyle Larson (+600), William Byron (+750), Tyler Reddick (+750) and Denny Hamlin (+750).
