A well-established atmospheric connection between the Southwestern monsoon circulation and a series of Northern cold fronts will contribute to widespread showers and thunderstorms during the next few days.
In fact, 5-day rainfall totals could reach 1 to 3 inches or more—leading to possible flash flooding—in portions of the Four Corners States and from the central Plains to the central and southern Appalachians. Some of the heaviest rain may fall around the middle of the week from the Ohio Valley into the central Appalachians.
However, not all areas will receive precipitation, as hot, mostly dry weather will prevail in the south-central U.S.
