Across the Corn Belt, a spell of warm, dry weather is nearly ideal for corn and soybean maturation and early-season harvest activities.
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. In addition, wildfires remain a threat in Texas and neighboring states.
In the South, isolated showers are confined to areas along the southern Atlantic Coast. In most locations, warm, dry conditions favor summer crop harvesting and other fieldwork. However, areas bypassed by Hurricane Irene and Tropical Storm Lee remain very dry and need rain to revive pastures.
In the West, 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.
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.
Meanwhile, significant precipitation (as much as 1 to 3 inches) will be confined to the Southwest, although briefly heavy showers may occur in the vicinity of the aforementioned cold front.
Looking ahead, the 6- to 10-day outlook calls for above-normal temperatures in most areas from the Pacific Coast to the Plains, while cooler-than-normal weather will linger across the Southeastern and Mid-Atlantic States. Meanwhile, above-normal precipitation along the Atlantic Seaboard and from the central Rockies into the upper Midwest will contrast with drier-than-normal conditions in the Far West and from the western Gulf Coast region into the lower Ohio Valley.
