Dec. 17-19 - where?

Looks like I have to be in San Diego for work on the 20th. So I think instead of flying out Monday, I'm going to take Friday off, fly somewhere, and then hop down to SD Monday night.

So, what are things looking like weather-wise up for that time period? I think my choices (based on being able to work the airfare out w/ work) are basically SLC, Tahoe, or Mammoth. Tahoe would probably work out the easiest, since getting to SD would be pretty easy/quick. But I could do any of them.

Doesn't look too promising from weather.com - Tahoe and Mammoth look bone dry through next Saturday, UT says dry until next Saturday, with "scattered snow showers" then.

What do the weather gurus have to say?
