Once you have installed Weather Watcher, you will have the possibility to indicate as many cities and places as you want, the program will search in the database if the city has meteorological stations, and it will show their data on the interface. Including a map in which you'll be able to see it just like on TV.
It's possible to configure several measurement units (Fahrenheit or Centigrade,...) to be able to know the temperature, pressure, humidity and wind speed (that will also include the direction). All this data will be viewed with daily maximums and minimums and the current temperature will also be shown with a large thermometer.
On the other hand, Weather Watcher includes the time at which the sun will rise and set.
