2015 NASCAR at Michigan weather forecast - threat of rain this weekend

No matter what weather forecast you look at, most if not all, are showing wet weather for Michigan International Speedway this weekend. While not a complete washout rain seems to be a nearly constant threat both Saturday and Sunday.

WILL NASCAR RACE SUNDAY? Saturday, I upped the odds of racing at Bristol Motor Speedway on Sunday to 40 percent. I am sticking with a 40 percent chance that NASCAR can race today. The forecast data I’ve been watching shows a break from the rain starting sometime between 5 p.m. to 9 p.m. ET. Please note, that 5 to 9 p.m. isNOT how long the break or window will be open but the time frame in which a possible window COULD open. Once we get a break in the rain, while it won’t be as steady and we could get a couple rain free hours in, there is still a chance for scattered strong storms later in the evening and overnight Sunday.

SHOULD I GO TO THE RACE SUNDAY? My answer on this hasn’t changed. I can’t, nor will I tell someone what they should do. If I paid money to go to a race, and as a meteorologist if I saw the smallest glimmer of a window, I’d probably take the risk and go, but that’s me. I recommend that if you are trying to decide whether or not to go, don’t just use my weather forecast but look at as many reliable weather sources as you can.

DO YOU THINK NASCAR RACES ON SUNDAY? Unfortunately, I can’t give a definite answer, that’s why I placed the odds at 40 percent. There are so many other things to factor, from track drying, to how long a potential break in the weather to when a NASCAR official decides to make the call on rain.

WHAT DOES MONDAY’S FORECAST LOOK LIKE? The weather forecast for Monday is better than Sunday. There’s still a good chance of showers on Monday but these showers and storms are more broken and scattered than the rain we get on Sunday. If NASCAR were to decide to postpone Sunday’s race to Monday, they should be able to get the race started and at least official if not complete.
