A wet & stormy pattern ahead for much of the Nation
During the next several days, cold air that has been building across Alaska and western Canada will edge southward. By week’s end, markedly colder air will arrive across the northern Plains and the Northwest.
Late in the weekend and early next week, sub-zero temperatures can be expected in parts of Montana. Widespread precipitation (rain and snow) will precede and accompany the cold air’s arrival. As below-normal temperatures further expand across the West early next week, beneficial precipitation may develop across California and the Great Basin. Meanwhile, an active pattern will continue across the South.
Five-day rainfall totals could reach 1 to 3 inches in the Southwest and from the southeastern Plains to the southern Appalachians. Mostly dry weather will persist, however, from southern Texas to peninsular Florida.
Looking ahead, the 6- to 10-day outlook calls for the likelihood of below-normal temperatures along and west of a line from New Mexico to Minnesota, while warmer-than-normal weather will prevail across the South, East, and lower Midwest.
Meanwhile, below-normal precipitation across Florida’s peninsula and the Pacific Northwest should contrast with wetter-than-normal conditions in all other areas of the country.
