USDA's Joint Ag Weather Facility says in the Corn Belt, a band of rain showers stretches across the southern tier of the region from the middle Mississippi Valley into the middle Ohio Valley. "Elsewhere, freezes were noted this morning in portions of the Great Lakes region, where producers continue to monitor early-blooming fruits and other temperature-sensitive crops in the wake of an ongoing series of cool outbreaks that began on March 26," USDA reports.
In the West, USDA explains warm weather across the central and southern Rockies and the Four Corners region contrasts with a surge of very cool air across the northern Rockies, the Great Basin, and the Pacific Coast states.
On the Plains, USDA says dry weather prevails in most areas. "In contrast, precipitation is beginning to overspread Montana's High Plains, where travel in wind-driven snow may become difficult by tonight — although the moisture will greatly benefit winter wheat," USDA notes.
In the South, dry weather has returned to the western Gulf Coast region, but showers and thunderstorms continue to affect the lower Mississippi Valley and parts of the Southeast, according to USDA. Rain is especially beneficial across the drought-affected lower Southeast, including Florida's peninsula, USDA explains.
USDA's outlook says a storm system drifting across the South will continue to produce scattered showers and locally severe thunderstorms into Friday. "On Friday and during the weekend, however, a high-pressure system will build across the eastern U.S., resulting in possible freezes as far south as the central Corn Belt, the lower Great Lakes region and the northern Mid-Atlantic states," USDA reports. Meanwhile, a new storm system will take shape across the nation’s mid-section, USDA adds. "Although precipitation will be limited with the latter storm—except for some much-needed, late-week rain and snow on the northern High Plains—cool air trailing the system could result in additional frost next week from the Midwest into the Northeast," according to USDA.
