I know....you are thinking what is he talking about, right? If you have read any of my previous posts, you probably know that I live in Tucson, AZ where we have 350 days of sunshine each year. Believe it or not, on Thursday, the National Weather Service had concurrently issued a winter storm warning, a high wind warning, a severe weather alert, a hazardous weather outlook statement, a blizzard warning, and yes, a tornado watch...all for an area within a 30 minute drive of the Lost Pleiad Observatory!!! Needless to say, we did not have a tornado, although a wind gust of 94 mph was recorded west of Tucson and Mt. Lemmon did have a blizzard.
Typically I observe the sun for about 10-15 minutes prior to starting a sketch. Today, there were many passing cumulonimbus clouds that would completely blot out the sun. As a result, I spent about 30 minutes observing before I began to draw. The seeing was quite poor- the temperature was 46F, humidity about 50%, with 5-8 mph breezes.
