USDA's Joint Ag Weather Facility says in the Corn Belt, snow is falling across the far upper Midwest, including the Red River Valley. "Elsewhere, isolated rain showers are occurring in the vicinity of a cold front stretching from Michigan to Missouri," USDA reports. Warmth in advance of the front’s passage contrasts with a return to or continuation of cold weather farther west, according to USDA.
In the West, USDA says frost and freeze warnings are in effect this morning in parts of the interior Northwest, including southeastern Washington and northeastern Oregon. "Cool weather also covers the remainder of the region, except for warm, windy conditions in parts of the Southwest," USDA explains.
On the Plains, USDA says warm weather prevails in much of Texas, but cold air covers the remainder of the region. "Snow lingers across eastern Montana and much of North Dakota," USDA adds.
In the South, warm, dry weather in most areas favors fieldwork and crop development, USDA reports. A few showers linger, however, in the Atlantic Coast states, it adds.
In its outlook, USDA says a storm system currently centered over Minnesota will move northeastward into eastern Canada. "Snow will subside later today over the north-central U.S., but rain showers will linger through Tuesday from the Ohio Valley into the Northeast," USDA details. Meanwhile, USDA says a stronger storm will begin to take shape across the nation’s mid-section, resulting in substantial, late-season snow accumulations from the central Rockies into the upper Midwest. "In addition, the latter storm will result in mid- to late-week downpours (locally 2 to 4 inches or more) from the southeastern Plains and Mid-South into the Midwest; severe thunderstorms from the Central and Southern Plains into the Southeast; and high winds from the Southwest to the Southern Plains," USDA continues. In the storm’s wake, temperatures could fall below 32°F as far south as the southern High Plains, and below 20°F on the central High Plains, on April 18-19, according to USDA.
