Winter Weather Advisory for the mountains

In the mountains, a Winter Weather Advisory (WWA) is usually issued when 6-12″ of snow are expected. At the beginning of the season or around holidays, it is quite normal for the National Weather Service to bend the rules a bit. At lower elevations, a WWA can be issued for 3-6″ of snow. This advisory does not include lower elevations. Our NWS office loves to throw Hesperus into the wording. They do not know how generically people use that word in our County. If it were me I would change it to Hesperus above 8,200′. But I don’t think they will do that, so if you live below 8,200 feet especially south of the fire station, know that you will not likely encounter the same conditions as are in the advisory.

I will be posting an update midday, there was very little change in the modeling for the Thanksgiving storm, but models are starting to track the Saturday storm further north than I would like to see.
