Minor changes to temperature in this update with warmer weather expected for Saturday. Sunday's conditions will begin mostly clear, though as the day progresses cloud cover will slowly move in due to southwesterly winds in the upper levels ahead of an upper level trough. Partly cloudy skies are anticipated for the Grand Prix, though heavier cloud cover will move in for the remaining on-track sessions. Northwesterly winds overnight and into the morning on Sunday will cause a cooler high for the day relative to the rest of the weekend. Fog remains a possibility for all three days, though Friday remains the most likely for foggy conditions during the morning.
