Cloud tops in those deeper Cu reached -30 C (-22 F) yesterday, plenty cold enough for lots of ice, with a few scattered very light showers reaching the ground, even a few drops here in Sutherland Heights a little before 5 PM, qualifying for a day with a trace of rain. Imagine! Rain! What izzat?
Here is that day below (if you want the short version, go to the U of AZ time lapse film department, online here).
Day Summary: Sunny with Altocumulus castellanus/floccus virgae in the early morning, then in the late morning, Cumulus humilis and mediocris, the latter with virga; Cu grew into shallow, but very cold Cumulonimbus capillatus (lots of “hair”-ice), with virga and RWU (rain showers of unknown intensity) in a couple of spots. Sunny again in mid-afternoon, but Cumulus re-developed in mid-late afternoon with more virga and some Cu reaching the shallow Cb stage with sprinkles here and there.
That’s it, in kind of a jumbled form. Hope you logged all these clouds and changes yesterday.
Don’t see any weather ahead that I like, and so not talkin’ about that today.
