drought to persist from the High Plains all the way to the West Coast, including the Pacific Northwest
The drought is the worst to strike the U.S. since the Dust Bowl era of the 1930s and lengthy droughts of the 1950s. It came on suddenly and largely without warning, and although the main trigger was most likely the pattern of water temperatures in the Pacific and Atlantic Oceans, the drought was exacerbated by extremely hot temperatures during the spring and summer. Climate studies have shown that the odds of severe heat waves are increasing due to man made climate change.
One year ago this week, Andrew Freedman said global warming caused Pacific Northwest drought. Now it causes too much precipitation in the Pacific Northwest.

In Seattle and Olympia, Wash., Sept. 28 was the wettest September day on record. In Seattle, 1.71 inches of rain fell, which was more rain than typically falls during the entire month.
A study published earlier this year found that climate change may contribute to the growth of atmospheric rivers, increasing the threat of associated flooding.
