Cool, wet pattern in position, for now...
A slow-moving storm system will drift from the central and southern Plains into the Great Lakes region by week’s end. Rainfall near the path of the storm could total 1 to 4 inches.
Locally, rainfall amounts of 1 to 2 inches with locally heavier amounts will be possible. Flooding may result from the heavy rainfall runoff into area river basins.
Farther west, warmth will develop across the Southwest and expand into the nation’s mid-section. At the same time, a cool, stormy weather pattern will evolve from the Pacific Northwest to the northern Plains.
The 6- to 10-day outlook calls for well above-normal temperatures across much of the eastern half of the U.S., while drier-than-normal conditions prevail from the lower Great Lakes States into the Northeast.
