Pressure maps show the expected air pressure for a day or a given time.

Pressure maps can be combined with temperature (colours), wind (streamlines), clouds (grey scale) or other parameters (see examples displayed). See the legend of each map for details.

Larger maps, which cover more than one time zone, use the date definition based on the timezone given in the legend. Therefore, some values may differ from local forecasts, since the time period used may include some hours of the previous or subsequent date on the West or East edges of the map. For local detail, consult more local maps or the local p☼int forecast.
