A change in weather ahead...
An impressive, late-season surge of monsoon moisture will continue to interact with disturbances crossing the northern half of the U.S. Mid-week rainfall could total 1 to 2 inches, with locally higher amounts, in the Four Corners States. Mid- to late-week totals of 2 to 4 inches or more may cause flooding in portions of the upper Midwest and the Great Lakes region.
Toward week’s end, precipitation will return to the Pacific Northwest, while tropical showers will increase along the Gulf Coast.
The 6- to 10-day outlook calls for near- to above-normal temperatures and near- to below-normal precipitation across the majority of the U.S. Cooler-than-normal weather will be limited to the South, while wetter-than-normal conditions will be mostly confined to the East, Pacific Northwest, and the Rio Grande Valley.
