In the West, dry weather persists. 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. In fact, only Arizona and New Mexico were reporting below-average storage on January 1.
On the Plains, temperatures are quickly rebounding in the wake of a brief cold snap. Chilly conditions linger, however, across the southern and eastern Plains. This morning’s temperatures dipped below 0°F in the eastern Dakotas.
In the Corn Belt, widespread snow showers continue downwind of the Great Lakes. Cold, dry weather covers the remainder of the Midwest. Some of the coldest air of the season covers the upper Midwest, where some locations reported sub-zero temperatures this morning.
In the South, isolated showers dot southern Florida. Cool, dry weather covers the remainder of the region. 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.
Outlook: 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. 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. During the next 5 days, 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. The NWS 6- to 10-day outlook for January 18- 22 calls for near- to above-normal temperatures nationwide, except for colder-than-normal weather from Washington to the upper Great Lakes region. Meanwhile, above-normal precipitation across much of the northern half of the U.S. will contrast with drier-than-normal conditions across the central and southern Plains and the Southwest.
