In the West, snow lingers across the southern Rockies, while dry, increasingly warm weather prevails elsewhere. This week’s snowfall did little to improve the overall poor water-supply outlook from the Sierra Nevada into the Great Basin and central Rockies.
On the Plains, colder-than-normal conditions across the south contrast with unseasonable warmth on the northern Plains. Today’s highs are expected to average more than 20°F above normal from Nebraska into Montana, likely encouraging some winter grains to break dormancy. Dry weather has settled over the southern Plains, although moisture is already leading to a return of showers in southern-most portions of the region.
In the Corn Belt, dry, cooler weather is settling into the Ohio Valley, where soil moisture remains abundant for winter wheat. Dry, increasingly warm conditions prevail across the western half of the region.
In the South, locally heavy showers are falling on the Delta. Farther east, showers are diminishing as they approach the primary drought areas of the Southeast, where warmer-than normal conditions are encouraging winter wheat and pasture growth. Meanwhile, rain is developing in Texas, aiding pastures and rangelands.
Outlook: A cold front will generate mostly light showers as it pushes through the southern Atlantic and Gulf Coast States. Meanwhile, an upper-air disturbance will interact with the tail end of the front over the weekend, which coupled with an influx of Gulf moisture will lead to locally heavy rain from central and eastern Texas into the eastcentral Plains and Corn Belt. Likewise, increasingly wet albeit cool weather is expected across the Northwest. Outside these two areas of rain, mostly dry, unseasonably warm conditions will prevail across the contiguous U.S., with daytime highs expected to average more than 20°F above normal from the central and northern Plains into the Mid-Atlantic and Northeast. The NWS 6- to 10-day outlook for March 14-18 calls for warmer-than-normal weather across most of the nation, with below-normal temperatures confined to the Pacific Northwest. Meanwhile, drierthan- normal weather along the East Coast, Southeast, and Southwest will contrast with above-normal precipitation across the Pacific Northwest and from the upper Midwest into the southern Plains.
