The winter forecast
           2009-2010

Despite a cool and somewhat snowy start to
 December, I don't hold out much hope for
       snow in the next two months,
    especially at the highest elevations.

Upslope is good:                                       Downslope is bad:
Air cools, condenses,                                  Air warms, dries, and
and clouds are born.                                   clouds are killed.
