Maps

3 subjects and 10 maps, each drawn from model runs we download and store ourselves. One map to a page — they share a coastline, and drawing it once per page is most of why they are no longer one long scroll.

• Temperature

  Where the models disagree about tomorrow's temperature, and what each one of them actually says.

  Spread · GFS · ECMWF · ECMWF AIFS · GEM · Time lapse · 24h Change

• Precip

  Whether anything falls at all, and how many of the models think so.

• Pressure

  The surface pattern as one model draws it, the rain falling under it, and how both have moved between runs.
