A colder pattern ahead

An intensifying storm system currently centered over eastern Kansas will move northward into central Canada, generating light rain over the upper Midwest before ushering sharply colder air into the central U.S. by week’s end. Heavy rain and locally severe thunderstorms will develop along a trailing cold front over the mid-South and lower Mississippi Valley Wednesday, with heavy showers reaching the Atlantic Seaboard by Thursday. Farther west, a Pacific storm system will race ashore, producing locally heavy rain and mountain snow from the Northwest into the central and northern Rockies, with rain and snow reaching the central Plains and Corn Belt by Friday. Meanwhile, the coldest weather of the season will overspread much of the central and eastern U.S. Friday into the upcoming weekend.

Looking ahead, the 6- to 10-day outlook calls for the likelihood of near- to below-normal temperatures across much of the U.S., while warmer-than-normal weather will be limited to southern Florida, New England, the Great Lakes region, and areas from southern California to Texas. Meanwhile, below-normal precipitation in the Pacific Northwest and much of the eastern U.S. will contrast with wetter-than-normal conditions across the Plains, upper Midwest, and Four Corners States.
