A Nor'easter in West Texas?!
Joe, when we get those, I start looking for something big.
Last time I was there was for Dive For Dan after Memorial Day. Drove between two or three F-1 tonadoes (hamrless, but impressive dust devils)

in 105 F air. By the time we did the Night Dive Treasure Hunt, the water was up to 78 F in the deep end.
But W-Texas is infamous for fast changing weather. Do not count on a 3 day forecast. Pecos Time & Temp is 432-445-2200, with weather forecast for next few hours. Low tonight is 55 F, but it's a dry cool, with no humidity to suck heat.
Pecos Dept of Tourism is 432-445-2406. Oh yes, the ground squirels will beg food, but don't touch. Rabies and bubonic plague are common among them.
This is West Texas. Watch for rattlesnakes in the brush and cotton mouths in the canal. You know, I'll bet the skeeters are still biting there in early November. Take Deet and Sunblock.
I mentioned that your cell phone won't work at the park. Even if you can call 911, get comfy and wait. Don't you love it when city dudes come to the desert?! :evil:
