Because it was drawn out over a few days and the soil was so dry, I doubt there was much runoff.

I know weatherman don't get it right every time, but one thing I think I'm starting to believe in is the accuracy of the La Niña/El Nino patterns. They said La Niña was over, and we were in the neutral ground. Then the floodgates opened.

I looked at rainfall patterns in the San Antonio area a few years ago as part of a permitting project, and some the wettest non-hurricane years in the San Antonio area were during transition from La Nina to El Nino. The rainfall in the area is actually fairly closely correlated to the ENSO index.
The interesting thing was how rare the "average" rainfall number was. IIRC the total rainfall was only within 8" of the "average" about 1/3 of the time. The other 2/3 were either drought or flood years.

The real control on moisture levels and rainfall for west Texas and most of the southern hill country is how much Pacific moisture makes it over the mountains from Mexico via the subtropical jet stream. The ENSO plays a big role in the strength of that jet stream and its positioning. With a weak jet or one diverted north toward California, most of the moisture stays west of the mountains and/or ends up in the cascades. With a strong jet, we get lots of 2-3 day 3-5" rainfall events scattered over several months time. Further East, the moisture comes from the Gulf of Mexico and is less dependent on the jet stream strength or position.AgLA06 said:txags92 said:WaldoWings said:

That's well said and not really a surprise to native Texans. The hill country is basically no man's land between coastal wet and west Texas desert. Depending on the low / high predominant wind patterns, you're more likely to get one or the other. It's not a coincidence the flora more resembles the desert except around live water. That's why I find it annoying as hell when people move there and then complain about lack of rain.
It's about as intelligent as Las Vegas residents being surprised they're running out of water.
