Meanwhile, a high-pressure system over the Great Lakes States will shift eastward, allowing warmer air to gradually expand across the central and eastern U.S.
Farther west, Pacific storms will maintain cool, showery weather as far south as central California, the central Rockies, and the Inter-mountain West. Early next week, a developing storm system over the nation’s mid-section could produce snow across the central Rockies and heavy rain from the central Plains into parts of the Midwest.
