Please let me know if you have more problems with these things. One thing I’ve been suspicious of lately is that one or more of the RAOB data sources may not be responding. If none of them are, WXSIMATE may get stuck trying and never produce fresh data (wdata.txt, for instance). If that keeps happening I may need to seek new data sources. meanwhile, a fix for that would be to not import RAOB (though it’s better if you can … at least for the first few hours of a forecast).
