Cold wave pattern to target the Heartland
The powerful coastal storm currently centered near the mid-Atlantic coast will move across the Canadian Maritimes on Wednesday, with slowly subsiding snow- and wind-related impacts in the northeastern U.S.
By Wednesday morning, however, freezes may extend into northern sections of Florida’s citrus belt.
Meanwhile, the storm system currently affecting the Northwest will push eastward, delivering wind-driven snow across the upper Mississippi Valley and the upper Great Lakes region on Thursday into Friday.
The most significant cold outbreak of the season will trail that storm system, with widespread sub-zero temperatures arriving across the northern Plains and upper Midwest during the weekend and persisting into next week.
High winds and blowing snow may accompany the Midwestern blast of frigid air, with wintry weather returning across the Northeast during the weekend. In contrast, dry weather will prevail during the next 5 days from southern California to the southern Plains.
Looking ahead, the 6- to 10-day outlook calls for colder-than-normal weather nationwide, except for near-normal temperatures in southern California, the southern Great Basin, and the Desert Southwest.
Meanwhile, drier-than-normal weather in the interior Southeast, Mississippi Valley, and west of the Rockies should contrast with near- or above-normal precipitation on the Plains, across the lower Great Lakes region, and along the Atlantic Coast.
