USDA's Joint Ag Weather Facility says on the Plains, warm weather prevails, particularly in western areas. "Today’s high temperatures will exceed 80°F as far north as western Nebraska," USDA details. The warmth is promoting a region-wide acceleration of fieldwork, but further stressing drought-affected rangeland, pastures, and winter wheat on the southern High Plains, according to USDA.
In the West, USDA reports a cold front is moving ashore bearing showers, including beneficial rainfall in parts of northern and central California. "Cool weather accompanies the showers, but warmth prevails in the Southwest," USDA reports.
In the Corn Belt, USDA says showers are ending across the Ohio Valley and the lower Great Lakes region. "Cooler weather prevails throughout the Midwest in the wake of a departing cold front, although a return to dry weather favors a limited resumption of fieldwork," USDA details.
In the South, USDA reports a band of scattered showers stretches from Kentucky to the lower Mississippi Valley. "Elsewhere, dry weather favors planting and other spring fieldwork, especially in the southern Atlantic states," USDA continues.
In its outlook, USDA says during the next five days, three storm systems will affect the nation. "The first storm, currently crossing the eastern U.S., will reach the Atlantic Seaboard by Tuesday night," USDA details. The second system, now affecting the Northwest, will traverse the nation’s mid-section before reaching the Great Lakes region by Friday, according to USDA. "The third storm will arrive toward week’s end in the West," USDA adds. Five-day precipitation totals could reach 2 to 4 inches in the Pacific Northwest and 1 to 2 inches across the remainder of the nation’s northern tier, according to USDA. Locally severe showers and thunderstorms could produce at least 1 to 2 inches of rain—along with high winds and large hail—from the eastern Plains into the Midwest on April 23-24, according to USDA. "During the weekend, markedly cooler air will arrive across the northern and western U.S. Meanwhile, an enhanced risk of wild fires will remain a concern across the southern High Plains and parts of the Southwest," USDA reports.
