More highly beneficial moisture for the northern Plains

A disturbance over the western Gulf of Mexico has a slight chance of becoming a tropical cyclone before moving inland Friday night. Regardless of development, the disturbance could spark another round of heavy rain in already flooded areas across eastern Texas and southern Louisiana.

During the weekend, the interaction between a plume of tropical moisture and a storm system emerging from the western U.S. will result in rain and snow showers across the Intermountain West; scattered showers and thunderstorms in the nation’s mid-section; and the potential for heavy precipitation (locally 1 to 3 inches) on the drought-affected northern Plains.

In contrast, warm, dry weather will prevail during the next 5 days throughout the Southeast. Dry weather will also cover much of California and the Desert Southwest.

Looking ahead, the 6- to 10-day outlook calls for the likelihood of warmer-than-normal weather from the central and southern Rockies to the Atlantic Coast, while near- or below-normal temperatures will prevail in the Far West and from the northern Rockies into the upper Great Lakes region.

Meanwhile, wetter-than-normal conditions across large sections of the Plains and Midwest should contrast with near or below-normal precipitation in the West, Deep South, and Atlantic Coast States.
