USDA's Joint Ag Weather Facility says on the Plains, bitterly cold air blankets the northwestern half of the region, where this morning’s lows ranged from 0 to -30°F. "Snow is insulating winter wheat across the northern Plains, but some wheat from eastern Colorado to southwestern Nebraska has been exposed to sub-zero readings," USDA continues. Farther south, wintry precipitation (snow, sleet, and freezing rain) continues to cause travel disruptions across the southeastern Plains, according to USDA.
In the West, USDA says cold, dry weather prevails. "Freeze warnings are in effect early today for much of central and southern California and the Desert Southwest," USDA elaborates. For the second day in a row, many of California’s citrus producers are utilizing protective measures to gua rd against the crop-threatening cold wave, according to USDA.
In the Corn Belt, USDA reports wintry precipitation (snow and freezing rain) is causing travel problems in the Ohio Valley. Elsewhere, cold, dry, breezy weather prevails, USDA adds. This morning’s temperatures fell below 0°F in the upper Midwest, with some readings near -20°F noted in northern Minnesota and the eastern Dakotas, USDA details.
"In the South, a severe winter storm—featuring snow, sleet, and freezing rain—is underway across the Ozark Plateau and neighboring areas," USDA reports. Rain is developing across much of the remainder of the South, although warm, mostly dry weather prevails in the southern Atlantic region, according to USDA.
In its outlook, USDA says very cold weather will continue to dominate areas from the Pacific Coast to the Mississippi Valley into next week. "Additional freezes can be expected through the first half of next week in California’s citrus areas, while low temperatures below 0°F will cover the northwestern half of the Plains through Dec. 9," USDA explains. Farther east, wintry precipitation will spread from the Mid-South into the northern Mid-Atlantic region on Dec. 6-7, followed by another round of snow and ice in the Mid-Atlantic states on Dec. 8-9, USDA continues. "Parts of the West, including some lower elevations in California, will experience some weekend snow," USDA reports.
