One GFS run, issued 00Z 4 Oct — played forward 6 hours at a time, from its analysis to 384 hours out.
Methodology
Two of this site's films laid one over the other. Underneath is the Run total: everything this run puts down from its start to each frame, on Tropical Tidbits' scale. On top is the pressure Time lapse: the precipitation falling at that frame's time, on the radar scale, and the sea-level pressure at that time in 4 hPa isobars. So the rate moves on as the film plays and leaves its total behind it. The first frame is the analysis, where the run has put nothing down yet.
The total is a window and the rate and the pressure are instants, all read at the frame's valid time: the total runs from the start of the run to that time. Liquid-equivalent: snow counts as the water it melts to. GFS and ECMWF only, the two models here that publish an instantaneous rate.
Six-hourly to 384 hours. GFS forecasts out to 384 hours. 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 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.
