Meteorological Forecast

The operational atmospheric forecasts use data from the Global Forecast System (GFS). The entire globe is covered by the GFS at a base horizontal resolution of 28 km. The model is run by NCEP four times a day: 00Z, 06Z, 12Z, and 18Z.  Each run produces forecasts of every 3 hours from the initial time out to 16 days.

There are any number of variables that can be queried from the model, but here we show the sea level pressure, the air temperature at 2m, the relative humidity, and the percentage of cloud cover.
