Another dry day yesterday, a tough one to take, since it appeared that rain hereabouts was a virtual certainty. All the model runs I saw from the U of AZ had good rains at times on the Catalinas yesterday afternoon and into the evening, as they do again for today. Here’s one U of A… Continue reading Looking for rain in all the wrong places…like here in Catalina

Thundery trace; expect more than that today
(A note: I am not getting WYSIWYG in what I am writing and what is posted in WP. This is SO FRUSTRATING! True I am a bit of an amateur at WP, but those spaghetti plots that start the blog are SUPPOSED TO BE AT THE END OF IT as I see them in the… Continue reading Thundery trace; expect more than that today
Lemmon bloom
Thunderstorms in the distance crept toward the Catalinas late in the day, and after sunset, an approaching, but thinning anvil of a dead Cumulonimbus cloud (no updrafts remaining to feed the anvil) produced this beauty. With the death of this prospect, any hope of rain moving in here later in the evening went six feet… Continue reading Lemmon bloom
68 F dewpoint in Catalina now; 0.31 inches overnight
68 F dewpoint at TUS, too. With this kind of dampness, it should be an exciting day with clouds topping the Catalinas, and you know when that happens, its another sign of really heavy rain in the area. In fact, we have a little strip of Stratus fractus along the base of the Catalina’s now… Continue reading 68 F dewpoint in Catalina now; 0.31 inches overnight
Late bloomers and a dry day; but plentiful rains dead ahead
Here’s a brief reprise of yesterday in photos. Expect a similar day today, late rising Cu over the Catalinas, isolated Cumulonimbus off on the horizon, probably NW-NE over the Mogollon Rim, and to the distant SE-S. None are expected to make it here. … Continue reading Late bloomers and a dry day; but plentiful rains dead ahead

That’s about all we can muster in Catalina these days it seems, just a trace of rain. Several drops came down out of stratiform debris clouds overhead around 7 PM. If you weren’t outside, or driving, you would never have noticed. I guess you could call those dull icy clouds with virga streaks hanging down… Continue reading Tracey
Early to rise
These small fluffs of Cumulus clouds above Ms. Mt. Sara Lemmon, were the first indications that something good, and very different from the previous two days was going to happen yesterday. These clouds appeared no less than 4 h earlier in the day (between 9 and 10 AM yesterday) than those first Cumulus on top… Continue reading Early to rise
Model trickeration, Dark Bluster, =s no rain!
You can see what didn’t happen here in the U of A time lapse movie. I got pretty excited when the U of A Weather Department issued a special report yesterday morning on what the Beo Wolf cluster had come up with in terms of yesterday and today’s weather. These kind of special, technical reports, ones… Continue reading Model trickeration, Dark Bluster, =s no rain!
Two thunderstorms, but no rain here
A thunderstorm is in progress when you can hear thunder. Yesterday, beginning at 1:20 PM, we were having a thunderstorm in Catalina due to those modest Cumulonimbus clouds on top of the Catalinas. Here are those clouds, ones that streamed northwestward and died. This first photo of an isolated, flat cloud is the remains… Continue reading Two thunderstorms, but no rain here
Cumulonimbi sightings; can rain be far behind?
No. Yesterday saw a gorgeous sight after our long cloudless spell; Cumulonimbus anvils approaching from the south-southeast in the later afternoon, our summer friends with their winds and rain squalls. The bottom of those thunderheads disappeared before they arrived over Catalina, and were just anvils, that icy portion above 30,000 feet or so, but they… Continue reading Cumulonimbi sightings; can rain be far behind?
