When I lived in serious snow country the standard weather oracle was a dedicated portable radio which broadcasts only national weather service forecast/status for the area. Most commercial radio stations basically rebroadcast that info with commercials and comments from on-air 'talent'.

Weather is one of my hobbies. I operate a full weather station and recommend these sites to anyone who is curious about the weather:

http://www.weather.gov/ (type in your city/state or for precise info use the latitude/longitude feature)
