One ECMWF run, issued 06Z 2 Oct — played forward 6 hours at a time, from 24 to 144 hours out.
Methodology
Each frame is the precipitation this run puts down in the 24 hours to it — its total at that hour less its total 24 hours before — so the film starts at +24 h, the first frame with a whole day behind it. 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 144 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. Every model's full forecast for any of these cities, or anywhere else, is in the beta: request an invite; it's free during the beta.
