USDA's Joint Ag Weather Facility says on the Plains, unusually warm, windy conditions prevail across the northwestern half of the region in advance of a Canadian cold front. "Most of the winter wheat remains exposed to potential weather extremes, except on the central High Plains—where some light snow fell on Thursday," USDA explains.
In the West, USDA reports a high-pressure system centered over the Intermountain region is inducing warm, windy conditions across much of California. "Immediate concerns related to California’s warm, windy weather and deepening drought include blowing dust and a heightened risk of wildfire expansion," USDA explains.
In the Corn Belt, USDA says mild air is temporarily overspreading the upper Midwest, accompanied by a few snow showers. "Cold weather persists across the remainder of the Midwest; sub-zero temperatures were noted this morning in the eastern Corn Belt as far south as the Ohio River," USDA elaborates.
In the South, USDA explains a rare winter storm is underway in the western and central Gulf Coast regions. "Significant travel disruptions are occurring in southeastern Texas and central and southern Louisiana due to snow, sleet, and freezing rain," USDA elaborates. Elsewhere, very cold, dry weather prevails, although winter agricultural areas across Deep South Texas and Florida’s peninsula did not experience a freeze, USDA continues.
In its outlook, USDA says frozen and freezing precipitation along the Gulf Coast will end later today. "Meanwhile, the latest in a series of Canadian cold fronts will cross the Midwestern and Northeastern states on Jan. 24-25, accompanied by snow showers," USDA reports. Another cold front will follow on Jan. 26-27, USDA adds. In the wake of the second front, a very strong surge of Arctic air will engulf most areas east of the Rockies, USDA continues. "By early next week, temperatures below -30°F can be expected in parts of the upper Midwest, while sub-zero readings will occur as far south as the central Plains and the Ozark Plateau," USDA reports. The Deep South will need to be monitored for possible freezes and wintry precipitation, according to USDA.
