NASCAR Weather Forecast: How Long Will Rain Delay Last in Kansas?

In a surprising NASCAR weather forecast twist, Sunday's AdventHealth 400 at Kansas Speedway, which was originally scheduled to go green shortly after 3 p.m. ET, is officially in a rain delay.

While there was a slight chance of rain in earlier forecasts, today's heavy rain has caught most NASCAR media members, fans and bettors by surprise.

According to FOX Sports' Bob Pockrass, it will take between 60-90 minutes for officials to dry the track once the rain stops, so let's dig into the updated NASCAR weather forecast for Kansas, including the chances that the AdventHealth 400 gets completed today.

NASCAR Weather Forecast for Kansas

According to the National Weather Service, there's just a 20% chance of rain for the rest of the day at Kansas Speedway.

Using the hourly weather breakdown, the chances of precipitation do not top 16% through tonight, which offers plenty of confidence for NASCAR getting in today's AdventHealth 400.

Further, Kansas Speedway does have lights, so even though we're currently in a delay, NASCAR should have plenty of time to dry the track and get in the full 400 miles with little rain expected into the evening.

And for those wondering, today's race will be official at the half-way mark, meaning once drivers complete Lap 134, NASCAR will not need to restart the event if it can't dry the track.

Per live NASCAR odds for Kansas, Kyle Larson is the race favorite at +250, followed by Denny Hamlin (5-1), Tyler Reddick (+725), William Byron (+825) and Christopher Bell (+850).
