Check it out for AZ and the SW! Will the drought be over in a week? This could be the best model run I have ever seen and that’s why I have links to it twice in one line even though it is based on data from yesterday morning, the 1st. (It will be replaced… Continue reading The Canadians are a great people having model runs like this…

Examples of “good” and “bad” model runs at 144 hours from this morning
First, let us examine the National Center for Environmental Prediction (NCEP) model that came out based on this morning’s data from around the globe. This first panel is for the winds around 500 mb (millibars, or “hectopascals”) and is at about 16,ooo to 20,ooo feet in the atmosphere, depending on how high or low the… Continue reading Examples of “good” and “bad” model runs at 144 hours from this morning
Nice!
These, and lots more of them yesterday. I think one of the lightning strikes associated with photo No. 2 down there was about 8 inches from the house! Also, there one particularly dangerous stroke from a thin anvil cloud just after 12 Noon yesterday as the first thunder began to be heard from a Cumulonimbus… Continue reading Nice!
Likable model runs continue; one of the best overnight!
Tired of being dry? Tired of having dry washes? Tired of seeing dust raised on your gravel road? Maybe too much dust on your late model car? Maybe you’ve been thinking about wanting some more humidity and cloud cover with RAIN to make to make you lose that feeling of fatigue and boredom? Well, then… Continue reading Likable model runs continue; one of the best overnight!
Its back! After going away on the model runs for a couple of days and I didn’t want to tell you about it thinking it could come back because the models can be kind of dicey on these things and it did
That vexious tropical storm is once again shown to move northward into Baja Cal and then its remnants move into the SW, combine with a winter-like upper air trough, and together produce some good AZ rains. After a period of depression about this tropical depression going to the west and dying instead of into AZ… Continue reading Its back! After going away on the model runs for a couple of days and I didn’t want to tell you about it thinking it could come back because the models can be kind of dicey on these things and it did
“Good” model runs continue, ones that bring substantial rain to AZ
I thought sure that late September-early October tropical storm entry into AZ and Catalina land would disappear; too good to be true. But today, after several more model runs, there it is, the remnant practically over where we live the afternoon of October 1st (2nd panel)! (These are National Center for Environmental Prediction (NCEP)… Continue reading “Good” model runs continue, ones that bring substantial rain to AZ
Good model
I like this model output from “12Z” this morning, and so I thought my other reader besides me would like it, too. These are the latest gov’t models as repackaged by IPS Meteostar–they do a great job at presenting weather stuff. These are for the afternoons of September 29th and 30th, respectively. Note hurricane (low… Continue reading Good model
The Tucson storm passes by Catalina like so many other September storms
With continuous thunder and threatening skies for Catalina, the mammoth Tucson storm that dropped a record 2.83 inches for the wettest day ever in September at the International Airport passed by Catalina early yesterday afternoon. Here’s what a fraction of it looked like (using a bad ISO setting, darn it). Also at the TUS AP… Continue reading The Tucson storm passes by Catalina like so many other September storms
Another summer thunderstorm day!
We’re on the cusp, of course, for the end of the summer rain season, and so every day like yesterday is a particular treasure. Take a gander here at the bulging morning Cumulus congestus and Cumulonimbus (albeit, marginal ones) clouds early on over the Cat Mountains. Note detached top of small Cb to left with… Continue reading Another summer thunderstorm day!
Scattered rain in AZ forecast next ten days!
Last night’s model runs continue to indicate a showery spell of no less than 10 days duration in the State of AZ. IPS Meteostar, a private weather provider, has repackaged the National Center for Environmental Prediction numerical model predictions here. No one cannot be excited by this prospect in view of our droughty August. What’s REALLY… Continue reading Scattered rain in AZ forecast next ten days!
