Forecast buttons
Four kinds of forecast are available. Click either button for your desired forecast. Upper air maps are also available for the largest regions. :
 Circles in maps:
Each circle on a map stands for a specific location, a city. Click inside it and the name of that city will appear to the right above the meteograms and in the top menu, together with the current weather forecast for that place. The numbers inside the circles are temperatures, these numbers are always degrees Celsius.
 Hour by hour buttons:
Use these three buttons to get forecasts in 1-hour steps to see how the weather forecast will develop. The middle button always takes you back to the present. You can also step backwards to see what the weather forecast was like before.
 Animation buttons:
Either of these four buttons starts an animation sequence of six pictures (one for each hour) that repeats six times and then stops. Each button covers a 6-hour period.
 Meteograms:
This is a meteogram. It consists of a combination of data: temperature, winds, precipitation and clouds over a 24-hour period, which is the horizontal direction. Vertical blue lines give 6 hour intervals. By clicking at different heights on the meteograms you navigate to a map of clouds, wind, temperature or rain for that hour.
The grey scale indicates the thickness of the cloud cover: the darker the line, the darker the sky above. Clouds are accumulated for all altitudes.
The red line stands for temperature in degrees Celsius. Read the temperature on the red scale to the left. On the timeline you can see what the temperature was, is, and will be for a particular hour.
The light blue area means precipitation (= the amount of rainfall, snow etc.) and is measured in mm/hour (millimetres/hour). Read the amount of precipitation on the scale to the left (same as the temperature scale). On the timeline you can see what the precipitation was, is, and will be for a particular hour.
The green line stands for wind speed in km/hour. Read the wind speed on the green scale to the right. On the timeline you can see what the wind speed was, is, and will be for a particular hour.
 Other scales
  Scale in temperature forecast:

The forecast shows temperature using coloured areas, where each colour stands for a particular range of temperatures in degrees Celsius. Under Settings you can change the scale to Farenheit. This will however not change the temperature numbers inside the circles or on isoterms which are always Celsius. The black lines are isobars with numbers in hPa.
 
  Scale in winds forecast:

The forecast shows wind velocity using coloured areas, where each colour stands for a particular range of wind speeds. The windspeed is also indicated by the size of the arrows. Wind speed in kilometres per hour is shown below the scale (0 .. 117). Under -Settings- you can change to other scales.
Range of wind speed [km/hour]
  Scale in precipitation forecast:

The forecast shows precipitation using white and grey coloured areas. Darker grey means more precipitation. The scale shows how the colours relate to precipitation in millimetres per hour. The red lines are isoterms with numbers in degrees Celsius.
Precipitation [mm/hour]
  Scale in clouds forecast:

The forecast shows cloud cover using white and grey coloured areas. Darker grey means more and heavier clouds accumulated over all altitudes. The wind arrows on the cloud maps give direction and force at 850 hPa. Refer to the wind maps to see the relation of force to arrow size.
