The forecast for the Grand Prix of Long Beach for IMSA and the NTT IndyCar Series really hasn't changed that much at all, with the exception of a slight nudging of the temperatures. Skies on each day will start off mainly cloudy, with some fog reducing visibilities during the morning. Eventually the fog will lift and clouds will dissipate as the noon hour approaches and skies will be partly cloudy to mostly sunny by the afternoon. Highs will top out in the lower to mid 70s. No rain is in the forecast.
