Oh, well. Was expecting at least 0.25 inches a few days ago, and thought maybe a heavy shower last night might pull that expectation out of the trash bucket. Monthly total now up to 0.70 inches (updated after reading NWS-style and CoCo gauges here), still significantly below average (0.96 inches). Not much else elsewhere, either. … Continue reading Storm disappoints with only 0.10 inches in Catalina

An interesting day from a cloud modification standpoint, one that doesn’t happen very often
Every once in a great while, we have days where fairly thick clouds do not produce even a sprinkle, even though their tops are a little below freezing, but not quite cold enough for natural ice to form. Yesterday was one of those days. And it was a day you, a cloud maven junior member, … Continue reading An interesting day from a cloud modification standpoint, one that doesn’t happen very often
Thunderstorms, rain, hail, pummel Catalina finally!
We’ve waited a LONG time for a rain day. It was so nice, so photogenic as well. I hope you enjoyed it as much as I did. Also, you may have seen the Froude Number1 in action as Cumulus congestus and Cumulonimbus clouds developed and went around the sides of the Catalina Mountains instead of… Continue reading Thunderstorms, rain, hail, pummel Catalina finally!
Awesome evening skies leave Catalinans with but a trace of rain, but over there by Picture Rocks, they got over an inch!
“Too many pictures, for one site…”, a continuing theme here1, to paraphrase “? and the Mysterians1“. Two stations near Picture Rocks reported 1.25 and 1.35 inches, respectively, so some major rain fell fairly close to us. You can see the amount arounds around the State or here at the Banner U of AZ rainlog,org site.… Continue reading Awesome evening skies leave Catalinans with but a trace of rain, but over there by Picture Rocks, they got over an inch!
Another day, another rainbow, another trace of rain; ho-hum
Kind of getting tired of gorgeous rainbows every day, ones without a lot of rain here in The Heights. But, here they are again: Upwind Cumulonimbus clouds faded as the trudged toward Catalinaland yesterday, bottoms evaporating, raining out, leaving only a big patch Altostratus cumulonimbogenitus way up (at least ten kft above the ground) there… Continue reading Another day, another rainbow, another trace of rain; ho-hum
Eruption! CDO ran big last night (updated with golf balls shown in the wash))
This just in Just back from a horsey ride with Zeus the horse. Rode into the CDO to see the surprising view that it had run bank-to-bank last night after that mighty cell passed by along the foothills. In the wash, were golf ball-sized golf balls scattered throughout the wash, indicating that it hit the… Continue reading Eruption! CDO ran big last night (updated with golf balls shown in the wash))
Rainbows and sunsets; also, fall weather coming in October!
Should be some good rain today in Catalina, FINALLY! Thinking maybe half an inch or so over the next 24 h, something decent, as tropical air drains o northward and over us out of tropical storm remnant, Roslyn (“Rozzi”). Clouds and weather interruption: Due to the name of our weather-affecting tropical storm, Roslyn, I am… Continue reading Rainbows and sunsets; also, fall weather coming in October!
A rare day, a rare “bird”; a day in which rain only due to the collision-with-coalescence process operateddeveloped; hold the ice
Yesterday was as rare a day in Catalina, Arizona as seeing the marbled murrelet in Olympia, Washington.1 Why? Our bit of rain (0.12 inches in Sutherland Heights) was only due to that formed by the collision-coalesence process, some times called the “warm rain” process, or more technically, non-brightband rain2. No ice needed. Usually clouds at… Continue reading A rare day, a rare “bird”; a day in which rain only due to the collision-with-coalescence process operateddeveloped; hold the ice
An unbelievably long blog about a surprise afternoon sprinkle of rain
A very few small, isolated drops fell between 4:50 and 5 PM here in Sutherland Heights from what appeared to be nothing overhead. You’d have to be really good to have not been driving, and to have anticipated the possibility (by recognizing ice in upwind clouds) and then having observed it. You would be recognized,… Continue reading An unbelievably long blog about a surprise afternoon sprinkle of rain
A thunderful day brings a little rain to Catalina, drenches the Tortolita Mountains.
The day started with some nice Altocumulus “pancakus”, some lenticulars and breezy conditions, reminding one of fall day with a cold front approaching. Small Cumulus appeared quickly, but with the wind, you wondered if they would get enough heating to power upward into Cumulonimbus clouds. By noon you had your answer as a large Cumulonimbus… Continue reading A thunderful day brings a little rain to Catalina, drenches the Tortolita Mountains.
