USDA's Joint Ag Weather Facility says in the Corn Belt, light rain is spreading across the southern tier of the region, including Missouri and southern portions of Illinois and Indiana. "Mild weather continues to melt or eliminate snow cover," USDA adds. Current snow depths in the upper Midwest include 3 inches at both Grand Forks, North Dakota, and Des Moines, Iowa, according to USDA.
In the West, USDA says scattered rain and snow showers are occurring along and northwest of a line from California to Idaho. "Meanwhile, mild, dry weather prevails in the Southwest," USDA reports.
On the Plains, USDA says generally light rain is providing limited drought relief in parts of Kansas, Oklahoma and northern Texas. "Meanwhile, mild, dry weather persists on the northern Plains, although cooler air is beginning to arrive in Montana," USDA reports.
In the South, USDA says heavy showers and locally severe thunderstorms are rolling across the lower Mississippi Valley, where some flooding is underway. "Heavy rain has ended across Texas, while warm, dry weather favors fieldwork including Florida's citrus and sugarcane harvests — in the southern Atlantic region," USDA reports.
USDA's outlook says a storm system that has been affecting the south-central U.S. will weaken by Friday while lifting northeastward into the Great Lakes and Northeastern states. "Meanwhile, a developing storm in the West will emerge from the central Rockies on Friday," USDA reports. As a result, USDA says late-week snow will develop across the northern Plains and far upper Midwest, while high winds will rake southern portions of the Rockies and Plains. "During the weekend, additional heavy rain will fall in parts of the western and central Gulf Coast states," USDA continues. Weekend rain will also soak the eastern Corn Belt, USDA adds. Sharply colder air will trail the Western storm, encompassing all areas from the Mississippi River westward by Sunday, according to USDA. "By Jan. 13-14, widespread readings below -10°F can be expected on the northern Plains," USDA adds.
