Not much change has been needed to the forecast I made on Monday, as I'm still expecting nice weather for the ABC Supply 500 on Sunday.
A cold front will move across the area on Friday, which will bring a good chance of storms that day. More stable air will build in at the surface behind the front, but an upper level trough will lag behind it and keep a slight chance of showers going into Saturday. There is a possibility of some isolated light showers around the track for the final practice session late in the day, but the showers should be so sparse and short-lived that I don't expect much, if any, impact. I think the timing of possible showers favors the late afternoon and evening hours, mainly 4 pm or later.
The models differ on how fast the trough will exit, and there may continue to be some showers into Saturday night. But I'm confident that any chance of showers will be gone by sunrise. Race day will be mostly sunny with pleasant temperatures in the upper 70s, and a northwest wind at 5 to 10 mph. Overall, a great day to be at the track.
