Information
  • The RRFS hourly maps come every hour, to 18 h, and to 84 h on the 00/06/12/18Z cycles. The cycles between the 3-hourly ones (01, 02, 04, 05Z ...) are made from the RRFS 15-minute output, which NOAA posts for them instead of the full hourly files: they start at hour 1 and carry the surface, precipitation, radar and wind maps, but no CAPE, clouds, smoke or upper air. The 15-minute radar steps in quarter hours (every hourly cycle: 15-MINUTE RADAR). The newest cycle fills in as NOAA publishes it; this page picks up new hours by itself.
  • Alaska and Hawaii come from their own RRFS grids (3 km and 2.5 km), hourly on the 3-hourly cycles like the CONUS maps. North America comes on the 00/06/12/18Z cycles: the whole continent from the 13-km grid every hour to 84 h, and Canada & US (3 km) from NOAA's 3-km subset every 3 hours to 60 h, then every 6 hours to 84 h.
  • LAGGED (6 RUNS) shows the current run beside the five before it, all valid at the same time: how the forecast for that moment has changed run to run.
  • SAVE LOOP makes an MP4 or GIF of what you are looking at, for all the frames or just a range, in your browser; SAVE IMAGE saves the map on screen, or the six lagged runs on one PNG. Nothing is uploaded.
  • A service of weathermodels.com. The maps are created from the highest-resolution (3-km) grid.
