Notes on GFS forecast maps
The Global Forecast System (GFS) is a National Centers for Environmental Prediction (NCEP)
weather forecast model that generates data for dozens of atmospheric and land-soil variables,
including temperatures, winds, precipitation, soil moisture, and atmospheric ozone concentration.
The system couples four separate models (atmosphere, ocean model, land/soil model, and sea ice) that work
together to accurately depict weather conditions.
GFS is a global model with a base horizontal resolution of 0.25° (28 kilometers) between grid points. The GFS is run 4 times a day, the temporal resolution covers analysis and forecasts out to 16 days.

For each run, temperatures (in °C) at 850 hPa (about 1300 m asl) and precipitation (in mm) are shown. Temperature values on the left axis, while those of precipitation on the right axis. For temperatures, a red line shows the 1979-2008 climatological mean temperature (source: NOAA) for the selected point on the grid.
NOTE: in central European countries, when solar time is in effect, the CET time is used, which is equal to UTC +1 hour, while when daylight saving time is in effect, the CEST time is used, which is equal to UTC +2 hours. Right now it is 9:32 UTC.
