Historic 2012 U.S. drought continues to expand and intensify

The great U.S. drought of 2012 continues to accelerate, and grew larger and more intense over the past week, said NOAA in their weekly U.S. Drought Monitor report issued Thursday, July 19. The area of the contiguous U.S. covered by drought expanded from 61% to 64%, and the area covered by severe or greater drought jumped from 37% to 42%. These are truly historic levels of drought, exceeded only during the great Dust Bowl drought of the 1930s and a severe drought in the mid-1950s. If we make the reasonable assumption that the current area covered by drought is representative of what the average for the entire month of July will be (based on the latest drought forecast from NOAA's Climate Prediction Center), the July 2012 drought is second only to the great Dust Bowl drought of July 1934 in terms of the area of the contiguous U.S. covered by moderate or greater drought. The five months with the greatest percent area in moderate or greater drought, since 1895, now look like this:

1) Jul 1934, 80%
2) Jul 2012, 64%
3) Dec 1939, 60%
4) Jul 1954, 60%
5) Dec 1956, 58%

[I remember as a little kid living up here in North East Ohio during the 1950s that there was not a lot of rain that storm activity then. I could be outdoors nearly every day. This did not change until the late 1950s as I remember.]
