Rain is needed to hold off severe drought

October is normally our second‑wettest month of the year — averaging just over four inches of rain at DFW Internatioanl Airport. So far this October, we’ve recorded only 0.24″ of rain.

This is much-needed moisture, with many locations across the area experiencing abnormally dry, moderate or severe drought conditions.
