Headlines

The mean mid-level circulation forecast for Week-2 shows a ridge off of the west coast of North America, a trough oriented from the north-central U.S. to the Southwest and positive height anomalies across the eastern CONUS. The pattern favors above-normal temperatures for western Alaska and much of the western southern and eastern CONUS, with elevated chances of below-normal temperatures for eastern Alaska, the Pacific Northwest, northern Rockies, northern and central Plains and the Great Lakes. Above-median precipitation is favored for most of Alaska, parts of the Southwest, the northern Rockies, northern Plains, Great Lakes, Ohio valley and Northeast. Below-median precipitation is favored for California. –Jon Gottschalck
