In the West, very cool weather prevails, while snow showers dot the Rockies and the Intermountain region. Recent precipitation has done little to change the spring and summer water-supply outlook, which remains especially bleak for California and the Great Basin.
On the Plains, light snow is falling across the northern tier of the region, mainly in North Dakota. Cool air is overspreading the remainder of the Plains, except for lingering warmth in central, southern, and eastern Texas.
In the Corn Belt, rain and snow showers are returning to the upper Midwest in conjunction with a developing storm. In the Ohio Valley, very warm weather favors some early-season development of winter grains.
In the South, scattered showers are developing in advance of an approaching storm system. Meanwhile, very warm weather continues to promote a rapid pace of pasture, winter grain, and fruit development. This morning’s temperatures are already averaging more than 20°F above normal, with today’s highs expected to easily surpass 80°F across much of the Gulf Coast Region.
Outlook: A developing storm over the middle Mississippi Valley will move northeast and intensify, generating rain in the Ohio Valley, with locally heavy, wind-driven snow expected across the Great Lakes Region. A trailing cold front will produce moderate to heavy showers and thunderstorms – some severe – from the Delta and lower Midwest to the Atlantic Coast States, although rain will mostly bypass central and southern Florida. During the latter half of the weekend, a fast-moving disturbance may bring some light snow to the northern Plains and Corn Belt, perhaps reaching the Mid-Atlantic by early next week. Out west, light snow will linger over the northern Rockies, while dry weather prevails from the Great Basin into California and Southwest. The NWS 6- to 10-day outlook for March 7- 11 calls for above-normal temperatures across much of the contiguous U.S., with cooler-than-normal conditions confined to the Pacific Coast States. Below-normal rainfall across the nation’s southern tier will contrast with near to above-normal precipitation from the Northwest into the Great Lakes and Corn Belt.
