WXSIM (Weather Simulator) is a powerful, truly one-of-a-kind tool for forecasting, or just plain studying weather. Its primary purpose is providing accurate, detailed forecasts tailored for your specific location, using a combination of imported real-time and model data (from the internet, plus optionally from your home weather station) and its own internal modeling capabilities. It can even improve its forecasts by learning from past results!
@Mapantz has spent time entering his data and getting the scripts to run based on his data, so.. if you look on his site he now includes WXSIM forecasts, based on his previously obtained data, and current data it "forecasts" what might happen in his locality going out over the next x days..
