USDA's Joint Ag Weather Facility says in the Corn Belt, freeze warnings were in effect early today across much of Ohio, with frost reported in parts of Indiana and Michigan. "This morning’s low temperatures in Ohio included 31°F in Cincinnati and 32°F in Columbus—both records for May 16," USDA details. Producers in freeze-affected areas are monitoring crops such as emerged corn and headed winter wheat for signs of injury, according to USDA. "Today’s cold weather in the eastern Corn Belt follows widespread weekend freezes across the upper Midwest as far south as northern sections of Iowa and Illinois," USDA reports.
In the West, mild weather is returning to some areas along and near the Pacific Coast, including northern California. Cool weather covers the remainder of the region, along with rain and high-elevation snow showers across the central Rockies and Intermountain West.
On the Plains, USDA reports a chilly rain is falling in many areas, particularly from Oklahoma to southern South Dakota. During the weekend, freezes were noted as far south as Nebraska, USDA adds.
In the South, USDA says heavy rain is causing local flooding along portions of the Texas Gulf coast. "Scattered showers dot the remainder of the western and central Gulf Coast states," USDA reports. In contrast, dry weather in the Southeast favors fieldwork, including cotton, peanut, and soybean planting, USDA continues.
In its outlook, USDA says a cool weather pattern nearly nationwide will be replaced by warm conditions in California and the Northwest. Below-normal temperatures will persist, however, in other areas of the country. Late in the week, another surge of cool air will arrive in the Far West. Widespread storminess will accompany the cool weather regime. Five-day rainfall totals could reach 2 to 4 inches or more from the central and southern Plains to the middle and southern Atlantic States. In contrast, little or no precipitation will occur from the northern Plains to New England. Late in the week, precipitation will accompany the return to cool weather in the Northwest.
