I just noticed some high clouds hugging the southern horizon.  This is the 
northeastern tip of a pretty significant amount of subtropical cirrus that 
shows up well on the IR image at the UofA site.

Animating this image shows a battle between that motion from the southwest and 
a trough that will be responsible for the northwest wind tonight.  I think the 
trough is going to win, so it should be clear.  Clear Sky Clock is not well 
initialized, and even the transparency forecast map does not show this stuff 
arriving until tomorrow.

The 10" and TV101 are already packed, so we're heading to Saddle Mountain.  
It's going to be in the upper 40's.  Brrrr.
