Saturday's weather will actually be nicer, with warmer temperatures and a cloud or two to offer some shade at times. A center of low pressure will be entering the southeastern U.S., causing winds to be out of the southeast at 8-12 MPH throughout the day. The good news is that it looks like nearly all of the rainfall will hold off until well after the track activity is over for the day, but I cannot rule out a very small chance of a stray shower moving through at some point during the afternoon hours. Afternoon highs will end up in the upper 70s, around 77 degrees, after starting off in the upper 50s at 7AM. Rain is expected to move in during the late night hours.
It is too early to know for sure what exactly will happen, but I'll have a better idea as we get closer to the weekend. My official forecast at this point will be cloudy skies with rain likely at anytime throughout the day. Rainfall could be heavy at times, and winds will be out of the southwest at 12-18 MPH with gusts up to 25 MPH possible. Afternoon highs may reach 80 degrees, but that is questionable depending on when the main bulk of the rain arrives in the area and how strong the southwesterly flow over the area is. 7AM temperatures will be in the upper 60s, around 68 degrees. Rain chance is set at 80%, but that could be bumped in any direction when the forecast changes.
Needless to say, rain tires (or tyres) will be likely on Sunday, but can we keep the rain from getting too heavy to prevent the cars from racing. I'll have your forecast updates throughout the week, and radar will be up and running on Friday. Have a great day and a great week!
