Headlines

The mid-level mean circulation pattern forecast for Week-2 indicates a trough across the northeast Pacific, a ridge from the western CONUS to southeast Alaska and a trough over the eastern CONUS. The forecast pattern favors above-normal temperatures across the western U.S., especially the Pacific Northwest, and also for the Alaska Panhandle. Elevated odds for below-normal temperatures are indicated for northern Alaska and for most of the central and eastern U.S. with the highest probabilities stretching from the central Great Lakes to the west-central Gulf Coast. Below-median precipitation is favored for much of the Pacific Northwest, northern Rockies and northern Plains with an enhanced likelihood for above-median precipitation for parts of the Southwest and the eastern third of the CONUS. For Alaska, below-median precipitation is favored for southwest Alaska during the period. --Jon Gottschalck
