A weather system centered over Nebraska will drift eastward, reaching the Mid-Atlantic region during the weekend. Widespread showers associated with the storm will affect the eastern half of the U.S., with 1- to 3-inch rainfall totals expected in most areas. Very cool weather will follow in the storm’s wake.
Meanwhile, a slow-moving storm will arrive in the Northwest, resulting in locally heavy precipitation and sharply cooler conditions. In contrast, mostly dry weather will prevail from southern California to the southern High Plains.
The 6- to 10-day outlook calls for below-normal temperatures and near- to above-normal precipitation across the majority of the U.S. except for drier-than-normal conditions in the Great Lakes region, the central Gulf Coast region, and from southern California into the Rio Grande Valley.
