One GFS run — issued 00Z 15 Oct — played forward 6 hours at a time, from its analysis to 384 hours out.

Methodology

Nights and days pass as you step this run: that motion is the weather the run forecasts, not the forecast changing. Forecast Evolution is the other film — it holds one moment still and steps the runs, so the only thing that moves there is the model's mind. The colour scale is fitted to the whole run at once, so the same moment reads with more bands here than on the static GFS map; the field is identical. Six-hourly to 384 hours. GFS forecasts out to 384 hours. The frames past the one shown load on demand.

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 NOAA. 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.

Sources and licences

What we change: each field is cropped to the frame these maps share when we download it, and each map then smooths, contours, differences or ranks those numbers as its Methodology says. These are our maps of the providers' numbers, not their products, and none of them has reviewed or endorsed this site.
