Document Description

Quarterly Climate Impacts and Outlook for the Western Region for September – November 2020.  Dated December 2020.

Temperatures were above-average during the fall west of the Rocky Mountains, favored by a strong high pressure ridge anchored along the coast. Although fall is typically dry in the southern half of the West, the persistent ridge prevented landfalling Pacific storms, leading to well-below normal precipitation in many regions.
