Low temperature records galore

Here a very nice site if you want to look at what weather records were being set around the country, with an example for the past few days below.  The one below were set as a gigantic blob of cold air (high pressure region) plopped down into the US, one bigger and colder than usual… Continue reading Low temperature records galore

Miriam’s sunset

At least former hurricane Miriam gave us a nice sunset of mostly layer ice clouds (Cirrostratus; Altostratus (where thicker).  Note portion of halo, upper center, above pointy-top cedar tree on the horizon.  Looks a broken streak of droplet clouds (Cirrocumulus) just below that  bit of halo. Today’s overcast of Altocumulus and Stratocumulus, also associated with… Continue reading Miriam’s sunset

Models converge; less is none

Oh, me.  I guess its great to be big enough to congratulate a people smarter than your people.  The Canadian model, a version of that used by the people of Europe, has seemingly won the battle of the Arizona rain question.  Almost no rain in Arizona is now predicted through the end of September in the… Continue reading Models converge; less is none

Pattern clouds, a few afternoon drops here, a lot over there, and a nice sunset

Pattern clouds: Cirrocumulus undulatus in odd, parallel lines.  I had not seen parallel lines like this before.  Fragments of Altocumulus are also present. Though only a few drops hit the ground here in Catalina, the day ended with a pretty sunset. This marked the third day in a row where large Cumuluonimbus clouds cells at… Continue reading Pattern clouds, a few afternoon drops here, a lot over there, and a nice sunset

Spectacular cloud day yesterday

Probably most people didn’t notice much yesterday, but at times, especially in the mid-afternoon it was spectacular up there due to delicate little patterns within Cirrus and Cirrocumulus clouds.  Some examples below. The Tucson rawinsonde sounding indicated that these initially liquid droplet clouds (Cirrocumulus and Altocumulus) were at 26,000 feet (at the 330 millibar level) above… Continue reading Spectacular cloud day yesterday

More flaming Cirrus; Dark Ages of climate science upon us?

More flaming cirrus this morning, perhaps reminding us of the ascension of the temperature later this morning.  In some photographic razzle dazzle, two photos have BOTH clouds and THE MOON!  The IR sat image loop makes it appear that we may have these kinds of clouds for at least a couple of days.  Below, I… Continue reading More flaming Cirrus; Dark Ages of climate science upon us?

Spinning on down from Glasgow to Rocky Point, a low

This is pretty interesting; don’t see this happen too often where a lobe of low breaks off and spins from Montana, back toward the south-southwest to pretty much over Rocky Point, MX, as you will see in this past 48 h water vapor loop.  In a water vapor loop, you pretty much see all that the… Continue reading Spinning on down from Glasgow to Rocky Point, a low

Pretty skies, but no castellanus (again)

Apparently the castellanus formations went over during the nighttime hours when we couldn’t see them… But it was a fabulous day again of interesting high and middle cloud flecks anyway.   Below, a reprise of yesterday’s clouds starting with that delicate patch of Cirrus passing over the Catalina Mountains with its tiny fibers of Cirrus… Continue reading Pretty skies, but no castellanus (again)

Castellanus anyone?

Lots of nice Cirrus clouds yesterday, but no Altocumulus castellanus later in the day yesterday as it was asserted there would be.  Only a flake or two of Altocumulus “uncastellanus”, (flat-as-you-can-get lenticular) clouds off in the distance (see bottom of page).  BTW, I obsess over being right.  I thought you’d want to know that about… Continue reading Castellanus anyone?
