How the forecast changed in 24 hours

This map isn't drawn right now. It needs a complete, recent model run in the grid store — every map here is built from runs we've already downloaded, never fetched on demand — and there isn't one it can use yet. The other charts may still have theirs; the ingest runs through the day.

Every map on this page is drawn from model output we store ourselves, not from anyone's picture of it. The per-city read of the same day — which cities the models are fighting about, and what the discussion makes of it — is on the national page.
