Saturday, highs will be warmer and the risk for thunderstorms will be a little less. A CAP in the mid-levels is expected to be established and it will be hard for storms to develop. If they do develop, rainfall amounts could be locally heavy on Saturday afternoon.
Radar will be up and running on the Pirelli World Challenge website. Just click the link posted beneath the Racecast Weather logo. I'll also have updates on our Twitter feed.
