Fortunately for this weekend's hot racing action at Iowa Speedway, it will be falling in between two active weather periods for the area. Seasonal temperatures can be expected for the Newton area throughout the weekend, and rain chances will be next to none for the scheduled on-track times for any of the three series that are running at the track. With an upper level ridge in place over the central plains, there is a possibility of a mesoscale convective system (MCS) developing and moving through on Saturday night. If that happens, it will more than likely happen closer to the 8-10PM time frame. Just to be on the safe side, that is why there is a 20% chance of rain on Saturday night, especially after 6PM. Other than that, expect mostly clear skies during the day with fair nights, with afternoon highs in the lower to mid 80s, with early morning lows in the mid to upper 60s.
