Across the Corn Belt, cool weather prevails across the upper Midwest, where an extensive snow cover remains in place. In contrast, unusually warm weather has developed across the southern and eastern Corn Belt.
On the Plains, breezy conditions and below-normal temperatures prevail across the northern half of the region, accompanied by patches of wintry precipitation. However, mild weather covers the southern Plains. Winter wheat’s protective snow cover has eroded, but extensive snow persists across the eastern Dakotas. Early Monday, snow depths remain greater than a foot in North Dakota locations such as Fargo and Grand Forks.
In the South, dry weather favors off-season fieldwork and farm maintenance activities. The Mississippi River has crested and begun to fall in all Delta locations; in Baton Rouge, Louisiana, for example, the river crested 4.91 feet above flood stage last Friday—4.27 feet below last year’s highest level, which occurred on March 18.
In the West, a developing storm system over the Intermountain region is producing widespread precipitation, including heavy, high-elevation snow. Throughout the region, chilly, breezy weather has replaced previously mild conditions.
In advance of a slow-moving storm system, record-setting warmth will prevail during the next few days across the South, East, and lower Midwest. Warmth will linger in the East through Thursday, but markedly cooler air will trail the storm into the western and central U.S. Freezes may occur, starting Tuesday morning, in California’s San Joaquin Valley and parts of the Desert Southwest. Meanwhile, significant snow will fall today in the central Rockies and environs. By Tuesday, heavy snow will develop across southern sections of the Rockies and High Plains. After mid-week, snow should develop in parts of the Northeast. Farther south, a heavy-rain event will unfold across the Southeast, where 5-day totals could reach 2 to 5 inches or more. Elsewhere, showery weather will return across the Northwest, starting around mid-week, while mostly dry weather will occur through week’s end across the upper Midwest and from California into the Desert Southwest.
Looking ahead, the 6- to 10- day outlook calls for the likelihood of below-normal temperatures across much of the West, while warmer-than-normal weather will prevail along and east of a line from western Texas to Lake Superior. Meanwhile, near- or above-normal precipitation across most of the country should contrast with drier-than-normal conditions in Florida and parts of the Pacific Coast States.
