Gentlemen,<p>Let me introduce you to the power of online snowfall telemetry stations. They usually report air temperature, wind speed & direction, precipitation, snow depth and water content in real time on an hour-by-hour basis. Find one or two nearby your local ski hill and study them for a season, comparing them to your in-the-field perceptions of ski conditions.<p>You'll soon be telling your friends about the "8 inches of cold dry powder that's just fallen on soft layer that was laid down last week" and distinguishing that from the "8 inches of heavy wet snow that just fell and then refroze onto the ice layer from last week".<p>For bonus points, take an avalanche safety course in your area. They will introduce you to a wealth of unbiased data sources. Mountain guides use these sources to maintain a deep understanding of the snow pack as it evolves throughout the winter season.<p>In the Seattle area, see <a href="http://www.nwac.us/weatherdata/map/" rel="nofollow">http://www.nwac.us/weatherdata/map/</a><p>In the Bay Area, see: <a href="http://www.wcc.nrcs.usda.gov/snotel/California/california.html" rel="nofollow">http://www.wcc.nrcs.usda.gov/snotel/California/california.ht...</a>
