An excellent & building site for weather webcams is
Weather Forecast & Reports - Long Range & Local | Wunderground | Weather Underground
Not only webcams but more weather stations in various places across the country with live data from personal weather stations which invariably are very accurate these days. I have been feeding wx and image data into this sytem now for almost a year
