Weather Forecasting

For several years now, making weather forecasts has been one of my hobbies. The weather forecasts are made using the Weather Research and Forecasting (WRF) model and are normally updated twice a day. In collaboration with Thomas Pettersen, we are working on a new web service. Take a look at the beta version here:

New weather forecast service (beta version)

Update June 2017: The forecast is currently down due to hard drive problems.
