Not much has changed in the expected weather pattern this weekend over Indiana. An upper level trough and a surface cold front are expected to cross the area Saturday night and Sunday. The frontal passage on Saturday night will bring some showers, and the upper trough will linger over the area through Sunday. This trough will create some instability that will produce scattered showers around central Indiana during the day. The chance of a shower at the track is about 30%. Showers are possible any time of the day, but the best chance is in the afternoon. I expect that any showers on Sunday will be light and short-lived, with low impacts on the racing. I don't expect any delays or red flag periods due to rain or lightning.
