USDA's Joint Ag Weather Facility says in the Corn Belt, cool, rainy weather prevails across northernmost areas, including the far upper Midwest and portions of the Great Lakes region. "Warmth covers the remainder of the Midwest. In the Ohio Valley, warm, dry conditions are promoting an acceleration of fieldwork," USDA explains.
In the West, USDA says very cool, unsettled weather prevails. Significant, late-season snow is falling at higher elevations of the northern Great Basin and environs, while rain showers are occurring at lower elevations, it details. "Farther south, an elevated to critical risk of wildfires exists in parts of the Southwest due to dry, breezy conditions," USDA continues.
On the Plains, USDA says warmth lingers from Kansas southward. In contrast, unusually cool weather prevails on the northern Plains, accompanied by rain and snow showers that are halting fieldwork but boosting soil moisture for winter wheat and spring-sown crops. "Some of the most significant snow is falling in northern Montana," USDA details.
In the South, USDA reports warm, mostly dry weather favors a rapid pace of spring fieldwork, including planting activities, and crop development.
In its outlook, USDA says precipitation will continue to spread eastward across the nation’s northern tier, while a strong spring storm will emerge from the Great Basin. "By midweek, a low-pressure system will reach the central Plains before drifting eastward and weakening," USDA reports. Severe thunderstorms could be a threat, especially on April 26, across the central and southern Plains, it details. Potentially strong storms should spread into the lower and middle Mississippi Valley by midweek, it adds. "Late in the week, a new storm may result in locally heavy rain in the south-central U.S. Five-day rainfall totals could reach 2 to 5 inches from the central and southern Plains into the lower Midwest, according to USDA," USDA continues. Warmth will prevail across the South, but most other areas of the U.S. will experience several days of below-normal temperatures, USDA explains.
