I threw the 5 degree figure in there as a average not taking in the inversion factor. Under normal circumstances, through my 15 years of being a regular to the valley, the valley is cooler than Davis due to the elevation there. The ridges can be considerably colder.
All I want to see for the season is a gradual cooling through November with temps falling into the 30's for highs and the upper teens for lows and staying there. Come December, I'd like to see several heavy, deep snows which will pack down and create the type of base which could last all winter making both back country and alpineskiers happy.
Come January and February, how about an average snowfall of 10-12" a week with an occasional dump for freshies!
By mid March, I'd like to see lots of sunshine and blue sky with an occasional snow to keep things looking and skiing fresh. Now if only the world were perfect......
