Precipitation Misses Dry Central Plains

Posted on 03/09/2017 10:19 AM

USDA's Joint Ag Weather Facility says on the Plains, cold, breezy conditions are engulfing Montana, Wyoming and the western Dakotas, along with patchy snow. Warmth lingers, however, especially across the central Plains, in advance of a strong cold front. Very dry conditions continue to adversely affect winter wheat across portions of the central High Plains, where precipitation since Sept. 1 in Garden City, Kan., has totaled just 0.29 inch (9 percent of normal).

In the South , one area of rain is exiting the southern Atlantic Coast , while another batch of showers and thunderstorms is affecting the western and central Gulf Coast States . The increase in Southern storminess , which began a week ago, continues to eases the effects of a significant autumn drought by replenishing topsoil moisture, reviving pastures, and increasing surface water supplies (e.g. lake storage and streamflow).

In the Corn Belt, USDA says mild, dry weather prevails in the wake of a weekend snow storm. On Dec. 4, official snowfall totals in Illinois included 7.8 inches in Moline and 6.4 inches in Chicago. Elsewhere, Midwestern snowfall on the 4th reached 5.7 inches in Madison, Wis., and 5.6 inches in Dubuque, Iowa.

In the West, cold weather across the northern half of the region contrasts with mild, dry conditions farther south. Across the Pacific Northwest, scattered rain and snow showers accompany the chilly conditions.

In its outlook through Dec. 9, USDA says for the remainder of today, cold air will continue to overspread the northwestern and north-central U.S. Elsewhere, accumulating snow will develop across North Dakota and northern Minnesota, while another round of rain will quickly spread across the South. Rain will shift into the eastern U.S. on Tuesday, with wintry precipitation expected in parts of the Northeast. By mid-week, a disturbance emerging from the Intermountain West will produce generally light precipitation — mainly snow — across central portions of the Rockies and Plains. Toward week’s end, stormy weather will return to northern California and the Northwest. Five-day precipitation totals could reach 1 to 4 inches in the Southeast and 2 to 6 inches in the Pacific Northwest. Meanwhile, cold weather will dominate the U.S., although late-week warmth will develop across the West in advance of Pacific storminess.
