50 actual shades of gray
Huh, Sounds familiar. Well, 50 shades of gray is a theme here at cloud-maven.com. Those various shades brought 0.02 inches of rain this morning to The Heights. Here are yesterday’s 50 shades:
This Altostratus invasion covered the sky within about 15 minutes, and that was it for sun, except some “filtered sun” at times (when this layer is called Altostratus translucidus (the sun’s position can be seen). Its an all ice or mostly ice cloud.
The weather ahead
Pretty much a sure-thing rain (we, unprofessionally forecast at least a 90-100% chance of measurable rain then) will move in late on the 16th or on the 17th. Should be a significant, vegetation-boosting rain, too–by that I mean at least a quarter of an inch–unlike this rain this morning. It looks,. too, like a second rain might move in a day or two after that one. Quite strong support in the ensembles (“spaghetti plots”) for that to happen, too. How great would that be? Very great, of course.
After that, the models are showing even more troughs affecting AZ, but the ensembles aren’t sure about it. Neither am I (CMP).
