USDA's Joint Ag Weather Facility says in the South, isolated showers dot southern Florida. "Cool, dry weather covers the remainder of the region," USDA adds. A freeze warning was in effect this morning in parts of southern Texas, although temperatures remained above 32° F in key winter agricultural areas of the lower Rio Grande Valley, according to USDA.
In the West, dry weather persists, USDA says. "Despite meager snow packs, especially from the Sierra Nevada to the western slopes of the central Rockies, Western reservoirs still have mostly above-average storage," USDA explains. In fact, only Arizona and New Mexico were reporting below-average storage on Jan. 1, USDA adds.
On the Plains, USDA says temperatures are quickly rebounding in the wake of a brief cold snap. "Chilly conditions linger, however, across the southern and eastern Plains," USDA reports. This morning's temperatures dipped below 0° F in the eastern Dakotas, USDA adds.
In the Corn Belt, USDA reports widespread snow showers continue downwind of the Great Lakes. "Cold, dry weather covers the remainder of the Midwest," USDA says. Some of the coldest air of the season covers the upper Midwest, where some locations reported sub-zero temperatures this morning, USDA reports.
USDA's outlook says cold weather will persist through the weekend in the East, with freezes expected as far south as northern Florida—but north of Florida’s citrus belt. "Meanwhile, a new blast of cold air will arrive across the Plains and the West early next week," USDA reports. Temperatures could fall to -20°F on the northern Plains, mainly near the Canadian border and east of the region’s primary winter wheat areas, according to USDA. During the next five days, USDA says most areas from California to the Plains will remain dry. "Elsewhere, precipitation will overspread the Northwest early next week, while a developing storm will produce rain in the East and some snow in the Midwest," USDA explains.
