Jason WXSIM is a great program and has an ever steeper learning curve that WD :lol: You have to use WXSIMATE to import WD data into WXSIM and WXSIM needs to import a load of data into itself. Customising the program is pretty much what you pay for when you register Tom spends quite a lot of time setting it up for your location and since it looks like you are in the USA then you have a huge amount of free data to work with. I have found it pretty good at forecasting for the next 24 to 48 hours when compared to our own Met Office here in the UK. It is very difficult with my very limited experience to say what you need to import. This is where Tom’s customisation gets you started, from then on you can play with it to tweak your forecasts for your local area…
