Forecast buttons
| Seven kinds of forecast are available. Wind, Cloud, Temperature (incl of Isobars), Precipitation, Snow, Freezing rain and Upper air maps (700, 500 and 300hpa). |

Wind
| 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). You can change to other scales using the drop down menu upper right. |

|
Cloud
| 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. |

Temperature and Isobars
| 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. |

Precipitation (Rain, Snow, Freezing Rain)
The forecast shows rain usinga green scale, snow using a blue scale and freezing rain using a red scale. Darker colours within each scale mean more precipitation.
The scale shows how the colours relate to precipitation in millimetres per hour or centimetres per hour for snow. The red lines are isoterms with numbers in degrees Celsius.' |

Upper air
| Upper Air Maps Show wind strength and direction by the arrows at 700hpa, 500hpa and 300hpa. The yellow lines indicate the height in meters and the red lines indicate the temperature at that height. |

Circles in maps
Each circle on a map stands for a specific location, a city. Click inside it and a meteogram with the name of that city will appear in the bottom left hand corner.
Click on the x box within the meteogram to cancel the meteogram. The numbers inside the circles are temperatures, these numbers are always degrees Celsius. |

Animation functions
Choose from day 1 to 6 by clicking in the button. You can now run the animation sequences for that day by using the four buttons (flimstrips). Each one runs a sequence of six maps (one for each hour) that repeats six times and then stops. Use the -1hr and + 1hr buttons to navigate hour by hour. The stop button stops the animation. |

Meteograms
It consists of a combination of data: temperature, winds, precipitation over a 6 day period noted on the horizontal base line.
Vertical dotted lines give 6 hour intervals. Wind is measured against the right hand green scale (km/h). Temperature is measured against left scale in celcius. Precipitation types are measured in mm per hour. However Snow is measured in cm per hour.
