USDA's Joint Ag Weather Facility says on the Plains, very warm, dry weather prevails. "Such conditions are favorable for crop maturation and fieldwork across the northern Plains, but are causing further drought intensification on the parched southern Plains," USDA reports. In addition, USDA says wildfires remain a threat in Texas and neighboring states.
In the West, USDA says isolated showers are mostly confined to the Great Basin and the Four Corners States. "Elsewhere, a late-season warm spell is promoting crop maturation and fieldwork, including Northwestern winter wheat planting," USDA explains.
In the Corn Belt, USDA says a spell of warm, dry weather is nearly ideal for corn and soybean maturation and early-season harvest activities.
In the South, USDA says isolated showers are confined to areas along the southern Atlantic Coast. "In most locations, warm, dry conditions favor summer crop harvesting and other fieldwork," according to USDA. However, areas bypassed by Hurricane Irene and Tropical Storm Lee remain very dry and need rain to revive pastures, USDA explains.
In the outlook, USDA says late-season warmth will come to an abrupt end across the Plains and Midwest in the wake of a cold front’s passage. "During the mid- to late-week period, cool air will become entrenched from the Plains to the East Coast, with widespread frost expected from the upper Midwest into New England. Warmth will linger, however, in the Northwest," USDA reports. Meanwhile, significant precipitation (as much as 1 to 3 inches) will be confined to the Southwest, USDA reports, although briefly heavy showers may occur in the vicinity of the aforementioned cold front.
