Over the next five to seven days (Feb. 12–17), a widespread and active precipitation pattern is forecast across much of the western and southern U.S. The heaviest totals are expected from eastern Texas into Arkansas, where widespread amounts of 3 to 5 inches are forecast, with locally higher totals possible. Additional areas of 1 to 3 inches are expected across much of the lower Mississippi Valley, central Gulf Coast, and into portions of the Southeast. Farther west, widespread precipitation is forecast across California, the Great Basin, and into the central and northern Rockies, where liquid-equivalent totals of 1 to 3 inches are expected, with locally higher amounts in favored terrain. Lighter but still meaningful precipitation is forecast across portions of the Midwest and into parts of the Mid-Atlantic and Northeast. In contrast, much of the northern Plains is expected to remain relatively dry during this period.
The Climate Prediction Center’s 6-10 day temperature outlook (Feb. 17–21) favors above-normal temperatures across much of the central and eastern U.S., including the Plains, Midwest, Ohio Valley and Southeast. The strongest probabilities for above-normal temperatures are centered over the central Plains and lower Mississippi Valley. In contrast, below-normal temperatures are favored across much of the West Coast and portions of the Great Basin. Alaska favors below-normal temperatures across much of the mainland, while Hawaii is favored to see above-normal temperatures.
The CPC 6-10 day precipitation outlook (Feb. 17–21) favors above-normal precipitation across much of the western United States, including California, the Great Basin, and the northern and central Rockies. Above-normal precipitation is also favored across parts of the northern Plains and Upper Midwest. In contrast, below-normal precipitation is favored across the southern tier from southern Texas eastward across the Gulf Coast and into Florida. Much of the central United States, including portions of the Tennessee and Ohio Valleys, is favored to see near-normal precipitation during this period.
