During the Holiday Weekend  and early next week, a cold front will cross the Plains, Midwest, and East, producing scattered showers and thunderstorms. In contrast, mostly dry weather will prevail in the Southwest.
The West’s latest cool outbreak will ease during the weekend, as cooler air temporarily shifts into the northern Plains and upper Midwest.
Looking ahead, the 6- to 10-day outlook  calls for below-normal temperatures in the Pacific Northwest and from the middle and upper Mississippi Valley into the Mid-Atlantic and Northeastern States, while above-normal temperatures will prevail from southern California to the High Plains. Meanwhile, near- to above-normal precipitation can be expected nationwide. Wet conditions will be most likely in the Northwest and a broad area centered on the Ohio and Tennessee Valleys.
