Friday will be the wettest day of the three, with a slight chance of a shower or storm during the morning hours, but with the heating of the day we'll see more showers and storms developing back to the west associated with a low. Those early showers will be isolated to scattered in nature, but the later storms will be more in coverage. Winds will be a little gusty at times as well, up to 25 MPH at times. For the most part, winds will be out of the south at 10-15 MPH. Afternoon highs will be up in the mid-70s, and the chance of rain at this point is around 50%.
At this point, it looks like the main concentration of showers and storms should be out of the area by 8AM on Saturday morning, but it will remain a little breezy and mostly cloudy. There may be a lingering shower afterwords for a couple of hours, but the chances of that are really small. Saturday's high will be in the lower 80s, with winds out of the southwest at 10-15 MPH.
Sunday will be the best looking day at the track with mostly sunny skies. With the heating of the day we could see the development of an isolated shower or storm around the area, and the chances of one passing over the track is around 20%. It will be warmer and not as breezy, with highs topping out in the mid-80s, and winds out of the southwest at 5-10 MPH.
