Cedar fever

It’s not really cedar (it’s juniper) and it’s not really fever (but it sure feels awful), and its pollen  presence is high as a kite this weekend, according to the pollen-counting meteorologists at KVUE-TV in Austin, the only ones who do their own pollen counts:

"Sunny skies and warmer weather has led to an explosion of Cedar pollen today. More than 1200 grains were found under the microscope. Molds remained at medium levels. This allergy forecast was updated on Friday, January 5th. Samples are reported in grains per cubic meter of air."

Allergies are one of the seldom-mentioned drawbacks to life in Central Texas, and cedar fever is the worst of the lot. 

Nice rains

Only about an inch in the Austin area in the past 24 hours, but the watershed of the lakes is doing much better with one and a half and a little more around the Pedernales River and almost two inches around the Llano River–with more yet to come tonight and tomorrow, although a lot of it has moved off east of Interstate 35 by now.

Rain starting slow

Looking at the hydrologic data of the Lower Colorado River Authority’s river operations center at this time of the morning, you can see that Central Texas has had precious little so far of the rain we were promised through tonight–only about a quarter of an inch at one gauge on the Llano River, the same on the San Saba, with almost a third of an inch on the Cherokee but not even a tenth of an inch so far on the Pedernales River. These are readings from automated gauges northwest of Austin in the Colorado River watershed, one of the best ways of gathering intelligence about how a rain event is shaping up. You have to choose a display at the link and "rainfall–since midnight" is the best in this situation. National Weather Service says severe storms possible as the day wears on, so may have shut down the ‘puter at the Rancho off and on. But when you’re in the midst of a bad drought, that’s not much of an annoyance.

UPDATE  At 1 p.m., meteorologist Troy Kimmel says we’re under a tornado watch until 8 p.m. Then it was extended until 2 a.m. But, by midnight, 2 inches seemed to be the highest total rain for the Austin area. Not much, really, but we’ll take it.

Here comes the rain

Lower Colorado River Authority meteorologist Bob Rose says the jetstream is turning south and we may finally begin to get some of the rain the El Nino oscillation has been promising since Turkey Day.

"The latest forecast solutions call for a storm system to move across northwestern Texas (today) and Friday, followed by another storm system about next Wednesday and Thursday.
"Yet another storm system is forecast to move across Texas around January 7th and 8th. Each of these storms systems is expected to bring at least some rain to our region, but due to their progressive nature, none appear to be excessively wet."

Santa come and gone

Knee-deep in torn wrapping paper, the only sound at the Rancho is Mr. B.’s delighted chatter about such as his new Lego X-wing fighter, his Leapster math games, and his Nerf-ball target set. Since he got us up at 6:30 this morning, and although the sun is out for the first time in several days, the wind is gusting to 20 mph, so Mom and Dad are taking it slow and easy. Later, at supper, the sound of popping Christmas crackers. I got the orange crown.

More vanishing lake

This gives a better idea of how low Lake Travis is these days. This ditch (about half a mile south of the previous photo) was a tributary off Cypress Arm before the drought and those sheltered swim platforms at the bottom used to float near the shore. The whole lake-reservoir, of course, used to look like this (albeit without any water) before Mansfield Dam was erected in the early 1940s stoppering the Colorado River–the Texas Colorado, not the more famous one–to create the lake. We have had a bit more than 1.5 inches of rain at the Rancho in the past 24 hours, the best rainfall in several months. But it will take a lot more in the lake’s watershed (principally the Llano and Pedernales rivers) to bring the lake back up to normal.

Texas drought

I said in the previous post that the drought was "savage," and then began to wonder if I was exaggerating. This might be a trifle hard to read as I had to compress it a little to get it on the page where I want it. But it shows that Central Texas, indeed, is in severe to extreme drought, and things haven’t improved in the four days since the graphic was made by NOAA. Driving around Lake Travis yesterday to get the photo below, I kept seeing signs warning about the potential for grass fires. Lots of houses back in the brush. Amazes me I have not heard of any of them burning up in grass or brush fires in at least twenty-eight years.
