Forecast is still on track for the Verizon Indycar Series and the Indy Lights Series. It will be really nice this weekend at Phoenix International Raceway, as a high amplitude ridge will be building in over the western United States during the weekend. This will allow for temperatures to be well above normal for this time of year, and it will keep rain chances out of the forecast. Sunny skies and warm temperatures with daytime highs in the lower to mid 80s for both days, with evening temps starting off in the upper 70s to lower 80s on both nights. Winds will be light and variable for both evenings, and rain is not a factor at all.
