Fall Weather

Fall Weather

The second spring seems to have come to an end since the lows are now in the mid-forties and the highs rarely get above 70. Fall is upon us, I’m afraid.

The porch thermometer was at 48° after nine this morning when we took the dogs for their first morning walk. With the little breeze blowing, it felt more like 38°.

The forecast is for warmer on the weekend when we will be attending our annual Bluegrass Days festival up at the rodeo grounds. More on that later. Meanwhile, enjoy the image of a nice cool afternoon in our corner of the desert. Click on the image to enlarge.

Sacred Datura

Sacred Datura

When we walk the dogs for their daily trip up the road, we pass a neighbor’s property which is still unimproved/unmaintained natural desert, complete with creosote, mesquite, cat’s paw and a host of native cacti. There is this one little shrub that we have been passing and not paying much mind to it. Recently, seed pods resembling blowfish have appeared. Out of curiosity, I went to our desert guide to see if I could find a match. I found Sacred Datura to be a match for what we were seeing.

I looked up sacred datura on Wikipedia and found that the binomial name was Datura Wrightii which is a hallucinogenic herb used by some native American tribes.

Datura wrightii or sacred datura is the name of a poisonous perennial plant and ornamental flower of southwestern North America. It is sometimes used as a hallucinogen. D. wrightii is classified as a deliriant and an anticholinergic.

It is a vigorous herbaceous perennial that grows 30 cm to 1.5 m tall and wide. The leaves are broad and rounded at the base, tapering to a point, often with wavy margins. The flowers are the most striking feature, being sweetly fragrant white trumpets up to 20 cm (7.9 in) long, often tinted purple, especially at the margin. Five narrow points are spaced symmetrically around the rim. It can bloom from April to October. In clear weather, flowers open at nearly full dark and wither a few hours after sunrise the following morning; in cloudy weather, they may open earlier and last longer.

The seeds are borne in a spiny, globular capsule 3 to 4 cm in diameter, which opens when fully ripe.

D. wrightii is found in northern Mexico and the adjoining U. S. states, as far north as southern Utah, in open land with well-drained soils. It is also commonly planted as an ornamental, especially in xeriscapes.

The name commemorates the botanist Charles Wright.

Given that it is used in xeriscapes, we might try and obtain some of the seeds to cultivate new plants we can use for the rock and cactus garden.

A Desert Rainbow

A Desert Rainbow

The end of the showers associated with the cold front that passed through here last evening produced this nice desert rainbow seen above our little cottage and the big saguaro as the sun began to set. Today, the cold air mass left in the wake of the front held our high temperature to about 61 degrees. A far cry from what it was a scant 30 days ago with daytime temperatures over 90 degrees. Oh, well, we just put on the long pants and sweaters and we’re OK. Click on the image to enlarge.

Weather Changing in Arizona

Rainbow

Over the past few days, the weather has played a role in the changing of seasons here. I’m not ready to call it Fall just yet, but we have had a pretty wet week thus far. The forecast has it warming up again toward the rest of the week, so I’ll assume we’re going to get into “Second Spring” for a few weeks before the really cooler weather settles into the desert.

Bob and I were out and about several times today; we had an early MD appointment, a post office PO box check, shopping at two different stores for last-minute specials that expire tonight and, finally, to pick up my pair of glasses that the O.D. office repaired. That was late this afternoon when the rainfall had moved east of town and the sun came out to form this beautiful arcing rainbow. Click on the image to enlarge.

Visit from the Local Javelina Herd

Local Javelina Herd

Damsel called me to the great room late this afternoon to show me the herd of Javelina (Collared Peccary) that had wandered onto the neighbor’s driveway across the road. As we looked through the window, I called the neighbor to advise him of the presence of the herd. He and the family were not at home at the time and he told me that his dogs were secure inside the house.

This herd has grown in size from when we first moved here, from about five to seven at that time to over a rough count of eleven today. Javelina herds stake out their own territory and seldom compete with other herds for the 5500 acres of desert where they claim domain and forage therein.

Residents in semi-rural areas just have to cope with the beasts, since they are considered a game animal here. Even so, a defensive gun use is not out of the question if they become aggressive, which they might, if startled or accompanied by offspring. Damsel and I both pack when not sleeping, just in case of trouble. either the four or two legged kind.

Linda – Eastern Pacific Hurricane

The activity in the Eastern Pacific tropics is still influencing the desert southwest. We’ve seen an extended monsoon season when we would expect second spring conditions to come to Wickenburg.

Hurricane Linda is the blob of activity west of Baja California seen in the infrared satellite map above, with obvious tendrils of tropical air and moisture coming to town. We had some showers today and this evening, but other parts of Arizona are getting some serious rainfall and flooding. Not that the desert can’t use the moisture, but . . .

By the way, it’s just weather. Not anything caused by other than solar and other natural influences on the planet. Just sayin’.

East Pacific Tropical Storms Energizing Monsoons

Tropical IR Map

Ever since East Pacific Hurricane Delores fueled one of the most massive rain dumps on our little town last July 18th, I have been keeping an eye on the EASTPAC tropical weather activity. There are two named storms in the infrared satellite image above: Hurricane Jimena on the left and Tropical Storm Kevin off the Baja California coast. Jimena is sort of headed to Hawaii and Kevin is slowly moving west northwest. The activity at the bottom of the frame is the usual inter-tropical convergence zone where there is almost always some activity.

You can see Kevin is sending a lot of moisture up to the southwestern US via Baja California and the Sea of Cortez. The moist tropical air meets the heated surfaces of the deserts and convective activity is inevitable, hence afternoon or nocturnal thunderstorms.

We had a group of storms pass closely to the east of town before dissipating earlier this afternoon and evening. We had a few raindrops and quite a bit of wind, but the most severe activity was well south of us along I-10, west of Buckeye, AZ.

We are alert for more monsoon weather through the remainder of this week and into the Labor Day weekend. We are hoping for a mild weather weekend, ourselves.
