Tuesday 22 September 2026 · AFTERNOON
Last word on each hour
This day has passed. There is no live forecast left, only the predictions made for it. The line above takes each hour from the last run that forecast it, so it matches no single row below. A day's final run covers only the hours still ahead of it; on its own it would describe the evening and lose the afternoon.
How this forecast changed
Each row is one stored prediction for Tuesday 22 September, from D+4, when the day first entered the forecast, up to the last run before the day ended. The hour columns are the same in every row. If a column changes colour as you read down, the forecast changed its mind. The label on the right is the window that run found. 2 predictions, oldest first. The last row is the last forecast made before the day ended.
Forecast, not weather
