Climate of 2004 - November
Northwest Region Drought

National Climatic Data Center, 13 December 2004

As noted by the USDA Natural Resources Conservation Service (Phil Pasteris), there was a significant contrast in early season snowpacks across the West. End-of-November snowpacks in Arizona, Nevada, Utah and parts of southern Colorado were well above average, while snowpacks in Oregon, Washington, Idaho, Montana and the east slopes of the Rockies were significantly below average. The Pacific Northwest (PNW) has fallen behind in early season snowpack accumulation during the past month due to the southern storm track.
