A cold front crossing the Plains and Midwest will drift eastward and gradually weaken, while a second front will arrive across the northern Plains and upper Midwest late in the week. Five-day Midwestern rainfall totals could reach 1 to 2 inches, with locally higher amounts. Meanwhile, the Southwestern monsoon circulation will become more fully established, leading to scattered showers in portions of the Four Corners States.
The interaction between the monsoon circulation and the two cold fronts should result in thundershowers on the Plains as far south as Texas’ northern panhandle.
