USDA's Joint Ag Weather Facility says on the Plains, chilly conditions prevail. Precipitation is still badly needed on the southern High Plains to arrest recent declines in crop and rangeland conditions, USDA reports. "On March 23, the portion of the winter wheat rated in very poor to poor condition stood at 55% in Texas, 42% in Oklahoma, and 21% in Kansas," USDA elaborates.
In the West, USDA reports wet weather is returning to the northern Pacific Coast. "Elsewhere, warm, dry weather continues to prematurely melt snow, especially in California and the Intermountain West," USDA explains.
In the Corn Belt, USDA says unseasonably cold, breezy weather trails Monday’ s light precipitation event. "This morning’s temperatures fell below 10°F in parts of the far upper Midwest," USDA details. Meanwhile, some light snow lingers from Michigan and Indiana eastward, according to USDA.
In the South, USDA reports unusually cold air is arriving in the wake of a departing low-pressure system. "Rain lingers along the southern Atlantic Coast, while mixed precipitation (rain and snow) is falling from the Tennessee Valley into the southern Mid-Atlantic region," USDA explains. The NWS has already issued freeze warnings, valid for Wednesday morning, mainly from Mississippi to South Carolina, due to the threat to tender vegetation, USDA continues. "In Georgia, for example, blooming had occurred by March 23 on 84% of the state’s peaches and 51% of the blueberries," USDA details.
In its outlook, USDA says for the remainder of today, a rapidly developing coastal storm will contribute to late-season snowfall in portions of the Mid-Atlantic atates. "Tonight and on Wednesday, the storm will graze the northern Atlantic Coast with heavy snow and high winds," USDA continues. Meanwhile, USDA says a prolonged period of heavy precipitation will return to the Northwest. "Five-day precipitation totals could reach 4 to 10 inches in the Pacific Northwest and 2 to 4 inches in the northern Rockies," USDA details. Precipitation will occasionally spread as far south as the Sierra Nevada, where totals of at least 1 to 3 inches can be expected, according to USDA. "Mostly dry weather will persist, however, from southern California to the southern High Plains," USDA adds.
