One ECMWF run, issued 00Z 1 Oct — played forward 6 hours at a time, from 6 to 240 hours out.
Methodology
Each frame is everything this run puts down from its start to that hour, so the map fills in as the film plays and its last frame is the run's whole total. Liquid-equivalent: snow counts as the water it melts to.
The colours are Tropical Tidbits' scale, so a reader who knows theirs can read this one. Three of its steps are re-shaded: at 0.5 in, at 2 in — where, on theirs, a reader with protanopia sees the 1.75–2 in band and the 2–2.5 in band as one colour — and among the yellows above 12 in. Same hues; the lightness is re-spaced so every step is visible in every common form of colour-blindness.
Six-hourly to 240 hours. ECMWF's 00Z and 12Z runs forecast out to 360 hours, its 06Z and 18Z runs to 144. The frames past the one shown load on demand. Uncorrected model output.
This map is drawn from model output we store ourselves, not from anyone's picture of it, and is based on data and products of the European Centre for Medium-Range Weather Forecasts (ECMWF). 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.
