NASCAR weather report: Rain, storms in Sunday’s forecast for Nashville

Please note that I am only the messenger here, but for the second straight week the NASCAR weather report isn't all that rosy (or dry, for that matter) ahead of a Cup Series race.

The latest NASCAR weather forecast for Sunday's Ally 400 (3:30 p.m. ET, NBC) isn't as bad as it looked ahead of last weekend's race at New Hampshire, but there is still reason to worry about a potential rain delay.

Rain and thunderstorms are in the forecast, but we're not looking at an automatic washout, either.

With this in mind, let's examine the expected weather for Sunday's race at Nashville, including whether rain will impact the Ally 400.

NASCAR Weather for Nashville

It's going to be hot, very hot, at Nashville Superspeedway.

Sunday's forecast is calling for highs in the low-90s, but a heat index as high as 106, according to the National Weather Service.

Further, there's a 60% chance of rain, though the timing of the precipitation and potential storms may work out for NASCAR.

There's a 47% chance of rain around the scheduled green flag Sunday, which then drops to 24% just two hours later.

Should the forecast worsen and force NASCAR to delay the start of the Ally 400, Nashville Superspeedway does have lights, so there should be plenty of time to wait out the rain, dry the track and get Sunday's race completed.

And just in case the weather is uglier than expected, the race will be official once lap 150 of the scheduled 300 laps is completed.

Denny Hamlin (+350) is the race favorite according to live NASCAR odds, followed by Kyle Larson (+425), Martin Truex Jr. (+700) and Christopher Bell (+700).
