Lubbock

Lubbock in NW Texas seems to be on the cusp between this region and the Texas/Oklahoma region. Neither prediction applies to us.

Lubbock just set a record 99 days (since 1911) with no measurable precip, from 11/8/17 to 2/15/18. It was broken 2/16 with .01" rainfall measured at the airport...

possible scary fire season

wow that is scary to hear of such bone dry conditions and already there have been some wildfires breaking out in south central areas of the west.

Jackson on global warming.

You nailed it. As you said, Jackson, plain and simple, the earth is always changing. Someone way more advanced than humans in charge of that. Praise Yahovah!
