Last Wednesday's NASCAR Cup Series race at Darlington Raceway was cut short by rain, and Sunday's Coca-Cola 600 at Charlotte Motor Speedway also saw a delay of almost 90 minutes due to weather, though the full 600-mile distance was completed.
And once again, rain is the forecast for Wednesday night's Alsco Uniforms 500 (8 p.m. ET, FS1) at Charlotte.
Let's take a detailed look at tonight's Charlotte, N.C. weather forecast.
NASCAR at Charlotte Alsco Uniforms 500 Weather Forecast
According to the National Weather Service, there's a 80% chance of rain in Charlotte for tonight's race, which includes the possibility of up to one-half inch of precipitation.
For those wondering, a NASCAR race becomes official once it reaches the halfway point, which is lap 104 tonight. In comparison, Sunday's Coca-Cola 600 was a 400-lap race, meaning it needed to go almost twice as long (200 laps) to become official.
This is an important forecast to monitor as the potential for a rain-shortened race is something bettors need to consider.
If rain is in the picture, drivers starting toward the front, like pole-sitter William Byron at +2000, will have a more significant advantage than those deeper in the field because this race, which is already short at just 208 laps, could run even shorter, giving drivers further down the running order less time to catch up to the leaders.
And from a NASCAR DFS perspective, the length of the Alsco Uniforms 500 already made dominators less important than on Sunday due to fewer opportunities for laps led and fast lap bonus points.
A shortened race due to rain makes targeting those bonus points even less essential.
Should tonight's race get postponed, NASCAR has announced it will be rescheduled for Thursday at 7 p.m. ET on FS1.
