Last season there was a Noaa link available that would give a 14 or 21 day? national radar picture prediction if I remember correctly it was a very long link address. it seems I cannot locate it and it seems to be useful in predicting areas of heavy snowfall from week to week nationally and locally. I believe it showed the jet stream highs and lows along with precipitation or cloud cover. John turned me on to this site a few years ago. any ideas
