USDA's Joint Ag Weather Facility says on the Plains, colder-than-normal weather persists in most areas, despite some moderation in temperatures. "Winter wheat retains a protective snow cover in many parts of the region; current snow depths include 5 inches in Wichita, Kansas, and 3 inches in Omaha, Nebraska, and Enid, Oklahoma," USDA details.
In the West, USDA reports abundant moisture is surging inland from the Pacific Northwest to the northern Rockies. "The moisture is boosting anemic snowpack in the Cascades, but warmth is melting snow at lower elevations of the Northwest," USDA explains. However, dry weather has returned to California, except the state’s northernmost tier, according to USDA.
In the Corn Belt, USDA says scattered snow showers stretch from Upper Michigan to eastern Nebraska. Elsewhere, cold, dry weather prevails, USDA adds. "Virtually the entire region remains covered by snow; current depths include 24 inches in Traverse City, Michigan; 13 inches in Minneapolis-St. Paul, Minnesota; and 10 inches in Rockford, Illinois," USDA elaborates.
In the South, USDA says a winter storm is underway from the Mississippi Delta to the Carolinas. "Heavy snow is falling in the southern Appalachians and environs, while freezing rain is glazing parts of the southern Atlantic states," USDA reports. Winter storm warnings are in effect from northern Louisiana to the Carolinas, and points northeastward, USDA continues.
In its outlook, USDA says for the remainder of today, another Southern winter storm, potentially more severe than the late-January event, will continue to unfold. "Severe, damaging ice accumulations can be expected from northern Georgia into parts of the Carolinas, while heavy snow will spread northeastward from the southern Appalachians," USDA reports. On Thursday, heavy snow will shift into the Northeast, while storm recovery efforts will begin in the Southeast, USDA continues. "Meanwhile, a series of potent storms will reach the northern Pacific Coast, producing heavy precipitation as far inland as the northern Rockies—but barely clipping northern California," USDA reports. Five-day precipitation totals could reach 4 to 12 inches in the Pacific Northwest, USDA details. "In contrast, dry weather will prevail through the weekend from southern California to the central and southern Plains," USDA explains. Elsewhere, a final batch of frigid weather will affect the Midwest and Northeast late in the week, followed by a period of above-normal temperatures nearly nationwide, according to USDA.
