Climate of 2003 - May
Wyoming Drought

National Climatic Data Center, 13 June 2003

Long-term hydrological situation in parts of the West is extremely dry. The USDA noted that mid-May conditions in southwest Wyoming and adjoining Utah included low streamflow, a snowpack that was gone up to 9500 feet, and a very dry Surface Water Supply Index (SWSI) indicators.

A detailed summary of May climate in Wyoming is available from the State Climatologist (Jan Curtis) at the following web page:
