I use same site as Paul but first go to the Current Conditions then scroll
down to the Hourly Weather Graph. I also find the Satellite Image useful,
especially the animated cloud cover view.
Here's the URL for Antennas
http://forecast.weather.gov/MapClick.php?lat=33.5854341&lon=-113.6337092&site=all&smap=1&searchresult=51595-52335%20Hovatter%20Road%2C%20AZ%2C%20USA#.VGj0CvnF9Ag
Note it goes by latitude and longitude.

For what it's worth, I prefer to use NWS sites that give "hourly weather
graph" forecasts for specified points. These hourly graphs give about ten
details such as sky cover, wind speed and direction, temp, etc. Unlike CSC,
the graphs go for four days out. Unfortunately, they don't give seeing
forecasts. Here's an example for Quartzsite, near the antennas:
http://forecast.weather.gov/MapClick.php?
w0=t&w1=td&w2=wc&w3=sfcwind&w3u=1&w4=sky&w5=pop&w6=rh&w7=rain&w8=thunder&w13u=0&w16u=1&w17u=1&AheadHour=48&FcstType=graphical&textField1=33.66390&textField2=-114.22900&site=psr&unit=0&dd=0&bw=0&BackDay.x=20&BackDay.y=14
Of course the URL would be without spaces. Notice the "forward and backward
2 days" buttons.

Thank you all for responding. I learned some things. Yes, the clouds
during the day were thick clouds, not cirrus. It seems to be clearing up
now except for some bothersome looking clouds, but they may dissipate by
6:30. The CSC was off this afternoon, but maybe it will be more accurate
tonight.
