Bringing the trash cans up from the street this morning, there was a thin line of clouds filling in the Cajon pass, their tops just below the rim of The Mesa (I think you can just catch a glimpse of them along the the lower left edge), but everything else in sight just a crystal clear, blue dome – except for this one, tiny, little cloud.
No clue what might be down that way to trigger a bit of air pressure differential of a plume of dust for the clouds to use as nucleates. Nothing off in that direction other than the high school, the Palmdale Bypass railroad tracks, and the freeway.
Mysteries, man!
