How the forecasts moved
Every reading we hold for 2026-09-28, newest column first, in °F. The bracket under each time says how long before the day that reading was taken (or after, once the day has started), so the table reads right to left as the day approached. A model still moving in the last day is a model that has not settled, and that is the one to distrust. Older readings are kept but not shown.
