This forecast is based upon data from my own weather station. The data is analyzed by the program WXSIM written byTom Ehrensperger. I have now made a page where I compare my own forecast withyr.no and actual temperature. Se menu "Compare forecasts". So far it lookes like my own forecast is better than yr.no!!

Contact me if you have comments or if you find an error.

The units are for the moment metric. I will try to change that later.
