A big change in weather from the Plains, westward


A big change in weather from the Plains, westward

Southeastern showers will diminish and shift toward the Atlantic Coast, ending by Sunday. However, a low- pressure system just east of the middle Atlantic coastline may produce some rain and gusty winds in the coastal Carolinas. Meanwhile in the Midwest, lingering showers will end later Friday.

Farther west, a trio of weather systems will result in unsettled, showery weather across a broad area during the next 5 days.

On October 8-9, precipitation associated with the first system will spread from the Intermountain West into the north-central U.S. On October 10-11. the second storm should deliver scattered showers from the central and southern Plains into the Midwest. Early next week, the third—and strongest— storm system will emerge from the Rockies and cross the central Plains. Weather extremes associated with the last system may include severe thunderstorms (along the storm’s trailing cold front), high winds (across the Plains and western Corn Belt), and heavy snow (in the central Rockies and adjacent regions).

Each of the three storms will help to reinforce a cool weather pattern in the West and maintain anomalous warmth in the eastern half of the U.S.

Looking ahead, the 6- to 10-day outlook calls for the likelihood of above-normal temperatures across the eastern half of the country, while cooler-than-normal weather will prevail from the Pacific Coast to the High Plains.

Meanwhile, near- or above-normal precipitation across most of the U.S. should contrast with drier-than-normal conditions in Maine, the southern Atlantic region, and the Southwest.
