On March 5, 2014, I noticed sun arcs at noon:

That evening I watched for more effects as I drove home. I was travelling, or else I would have tried to capture the unusual clouds to the west. At the same time, two friends from the Temecula Valley Astronomers were watching, one from Temecula, the other from Anza. Each had a better view that what I had. Here is what they saw:

Based on the photo, this was an impressive sun pillar (which is caused by ice crystals refracting the sun light in such a way that the light is spread out vertically).
A similar pattern occurred yesterday: interesting cloud effects in the morning, and good sundogs at evening:
Contrails on the morning of March 20
Right sundog on evening of March 20
Left sundog on evening of March 20
Both sundogs with the sun blocked by the tree
If you see something interesting in the morning, it's a reminder to get your camera and keep it with you for the day.
