A new storm on the Plains; colder air to return...
Across the Corn Belt, dry weather prevails in advance of an approaching storm. Recent precipitation has been especially beneficial in the eastern Corn Belt, where pockets of drought had developed in recent months.
On the Plains, a new snow storm is underway across the Dakotas and northern Nebraska, where a variety of winter weather advisories are in effect. Meanwhile, cold weather is returning to the southern half of the Plains, accompanied by breezy conditions. A portion of the central and southern Plains’ winter wheat crop is poorly established as dormancy begins.
In the South, mild, dry weather favors late-season harvest activities and other autumn fieldwork.
In the West, a cold weather pattern persists. Freeze warnings are in effect this morning in parts of California and the Desert Southwest, necessitating freeze-protection efforts in some areas. However, temperatures are not low enough to significantly threaten citrus fruits.
During the first half of the week, a low-pressure system will drift from the central Plains to the upper Great Lakes region. Snow will accumulate just northwest of the storm’s track, with the heaviest amounts expected from eastern South Dakota into northern Minnesota. Meanwhile, heavy rain will erupt from the central Gulf Coast States into the Northeast, with 1- to 5-inch totals likely. Precipitation may end as snow on Wednesday in parts of the interior Northeast.
Cold air will trail the storm system, although temperatures will rebound by week’s end from the Southwest onto the central and southern Plains.
Late in the week, wet weather will return to northern California and the Northwest.
Looking ahead, the 6- to 10-day outlook for calls for colder-than-normal weather across the eastern half of the U.S., while near- to above-normal temperatures will prevail from the Pacific Coast to the Plains. Meanwhile, below-normal precipitation across the majority of the U.S. will contrast with wetter-than-normal conditions in northern New England and much of California, Oregon, and the Great Basin.
