USDA's Joint Ag Weather Facility says in the Corn Belt, increasingly warm, windy conditions are overspreading the region, encouraging early winter wheat growth in areas free of snow cover. "Afternoon highs are expected to average more than 20°F above normal across western portions of the region," USDA explains.
In the West, USDA says much-needed snow is falling over northern portions of the Great Basin and Rockies. "Cold weather in the Northwest contrasts with above-normal temperatures across the southern Rockies," USDA adds.
On the Plains, USDA reports dry, unseasonably warm weather prevails. "Today's high temperatures are expected to average 20°F to 30°F above normal across the central Plains," USDA explains.
In the South, USDA says dry weather has returned to the region, promoting fieldwork and winter wheat development. "Recent heavy rain provided some drought relief in portions of the Southeast, while drought continues to intensify in central and southern Florida," according to USDa.
In its outlook, USDA says a storm and its attendant cold will sweep across the northwestern quarter of the nation, generating light to moderate rain and high-elevation snow from the central and northern Pacific Coast to the central and northern Rockies. "Ahead of this system, daytime highs will average more than 20°F above normal across the central Plains and Corn Belt, with warmer-than-normal conditions reaching the East Coast by mid-week," USDA explains. As the storm begins to tap into Gulf moisture, USDA says precipitation will intensify from the southeastern Plains and Delta into the Corn Belt on Thursday. "The northern portion of the front will continue eastward into the Northeast and Mid-Atlantic on Friday, generating widespread showers along its path," according to USDA. It continues, "The tail end of the front is expected to stall across the south-central U.S., leading to potentially heavy rain from the Delta into the interior Southeast and Tennessee Valley."
