..will be playing your favorite western tunes in the inimitable style of Johnny Cash at the Whistling Cactus Bar and Hitching Post this Friday and Saturday… :} (Hahahaha; “inimitable style of Johnny Cash”; that means Cash’s style can’t be imitated!)1
6:37 AM: I see now that there’s a lot more dust than last evening! Wow. Dusty Sunrise!
Today’s mix of clouds and dust
Cloud action today, likely some small Cu and Ac later today as a weak upper level trough approaches and passes over us. Should be enough clouds around to pose a sprinkle threat. Imagine.
Should be an especially interesting day for cloud watchers since the dust aerosol should get into the small Cu. Sometimes that can lead to much larger cloud droplets in them because the dust particles are so much larger than the usual aerosol stuff that gets into our clouds.
What does that mean?
Will help those lower Cumulus clouds to form raindrops, since the larger the cloud droplet, the higher the temperatures at which ice forms. Sometimes, even drizzle drops, formed from just droplet collisions can result in Cu mediocris clouds with large dust particles in them (no ice involved). Would sure like to have an instrumented aircraft in the clouds of today!
Normally, ice would be expected to form at temperatures below about -10 to -12 C here in AZ. Today, it might be higher with virga falling from shallower clouds than usual.
The weather ahead
Found some rain for ya… March 21st. See those green areas in SE AZ? Been quiet on rain lately. Don’t like to talk about rain when there’s none indicated for two weeks at a time. The rain shown for us on the map above has been coming and going around this date in the model runs, mostly going, actually, but scored one here based on yesterday’s 5 PM AST global data and that has allowed me to take the rain muzzle off.
So….in sum, we can look forward to another chance of rain in March, one just ahead, and, of course, more of “Dusty Sunset” in the meantime leading up to this chance.
1Saw a vinyl record album with those EXACT words on it in the Durango Market on Main Street, Durango, back in the ’70s when I lived there. Pretty funny, because you KNEW that imitating Johnny Cash was exactly what that singer was going to do!
