My thoughts on the forecast for the Bathurst 12 Hour this weekend haven't changed much from the last forecast. A low pressure trough will be over New South Wales all weekend, which will keep a chance of showers and thunderstorms each day, mainly in the afternoon and evening. Friday has the lowest chance of seeing a storm at the track as the low pressure trough will be to the north, but it can't be ruled out. I think the chances are low enough to lower the weather impact to None.
Saturday and Sunday are likely to have some weather impact. Moisture increases around Bathurst on Saturday as the low pressure trough will be in close proximity to the track. Showers and thunderstorms are likely in the afternoon and evening. As the trough moves south on Sunday, even more warm, moist air will move into the area to help feed afternoon and evening showers and thunderstorms. Rain amounts each day are expected to be between a tenth to a quarter inch (between 2 and 6 mm), depending on if a storm directly passes over Mount Panorama. This could result in a period of stoppage during the race, particularly in the closing hours.
