I just got this working in FS2004...but have been using it in CFS2 for a while. FSMetars is a free package that will download real time (or nearly real time) weather information from various weather station thingies and, via FSUIPC, link it to your sim. Very very nice. I was just up in Dutch Harbor, Alaska in NCGent's Fairchild F-91 and the haze and low lying clouds looked for superior to the stock FS2004 "real time" weather.
