The National Weather Service forecast for the start appears here from Sat, Dec 5, a week before race day.
This race is hand-checked. No feed we ingest carries it, so somebody read the organiser's own page and wrote the date down — which is also why it can be out of date in a way the rest of this site cannot. The link goes to the organiser.
