During the day yesterday I periodically checked the Phx Natl Weather 
Service forecasts for last night. The forecast was for partly cloudy 
skies and a 10%(I think) chance of rain. Yesterday, towards late 
afternoon it looked very bad and it looked like it would be a bad partly 
clouded night. However, by 8:30 nearly all the clouds cleared off, and 
by 12:30 it was completely clear. It probably completely cleared before 
then, but being in the dome I could not see the entire sky. If things 
improve for 5MM it will still be a very cold night from the rains. If I 
recall correctly form the one time I was there, even though we had not 
been in the spell of rain as we are in now, dewing of the corrector 
plate was a problem later in the night (around 11pm or so). With the 
recent rains, dewing may be even more of a problem.
