Texas Drought Relief

It appears that parts of Texas are finally going to get some rain.  Much of western Texas and Oklahoma have been as deficient of rainfall as California.  In fact, the Southern Plains and California are both in an ongoing drought for the same reason.  The cold phase of the Pacific Decadal Oscillation has been shown to correlate statistically with drought across the southwestern U.S.  So it is not unusual for these two areas to experience drought at the same time.  However, the warm, high-pressure ridge which is building across the central U.S. is forcing moisture from the Gulf of Mexico into the high plains of western Texas and Oklahoma where it will produce heavy thunderstorms this week.  California will probably not get any significant rain until this fall or winter.   Meteorologist John Wheeler
