Across the Corn Belt, rain is moving into central Missouri Valley in advance of the western winter storm complex, and a mixture of rain and snow lingers in the Ohio Valley and the northern Great Lakes Region, further stalling fieldwork.
On the Plains, a wintry mix of precipitation will intensify in amount and coverage throughout the day in northern parts of the region, resulting in hazardous travel conditions and stress on livestock. A Blizzard Warning is already in effect for parts of Wyoming, South Dakota, and Nebraska, and some freezing rain is forecast for the middle Missouri Valley.
In the South, dry, generally mild weather offers a brief opportunity for fieldwork from the Delta to the southern Atlantic Coast ahead of the next round of showers.
In the West, myriad warnings for hazardous winter weather — notably snow and high winds — remain in effect throughout much of the intermountain West as the powerful Thanksgiving storm works its way eastward. At the southern edge of the storm, Flood Warnings are in effect for southern Arizona due to the potential for locally heavy showers.
The winter storm system currently trudging through the nation’s midsection will advance slowly toward the Atlantic Coast through the weekend. By Sunday, upper Midwestern snow is expected to reach as far east as the eastern Great Lakes, with a mixture of locally heavy precipitation — including the potential for some freezing rain — dipping southward into the mid-Atlantic. Locally heavy showers and strong thunderstorms may also develop along the associated cold front in parts of the Deep South. Cold, windy conditions and another brief shot of snow are forecast for the Midwest in the wake of the storm before drier conditions develop. Meanwhile, the West Coast will almost immediately begin feeling the effects of a new Pacific Storm, with snow returning to the interior Northwest by the end of the weekend. The heaviest precipitation (3-day totals of 1-3 inches, liquid equivalent) is expected in northern California, adding to the snow pack but renewing disruptions in travel and transportation.
Looking ahead, the 6- to 10-day outlook depicts wetter-than-normal weather throughout the West, as well as on the northern Plains and in the upper Mississippi Valley; in contrast, drier conditions are expected in the East from the Gulf Coast to New England. Unseasonable warmth is forecast for the central and southern Plains, extending into neighboring sections of the Mississippi Valley and Four Corners Region. Meanwhile, cooler weather should prevail in parts of the Northwest and Northeast.
