Much-needed rain dampened several key drought areas, including the central and southern Plains and parts of the Midwest. Some of the heaviest rain, as much as 2-4 in., fell from northern Texas into the upper Mississippi Valley. Rain eased drought stress across the central Plains and western Corn Belt, but was insufficient to arrest the recent decline in crop conditions in the eastern Corn Belt.
Meanwhile, significant rain also soaked much of the South. Weekly totals of at least 2-4 in. were common from eastern Texas to the southern Atlantic States. However, only light rain fell in parts of the interior South, including the northern Mississippi Delta, where heavy irrigation demands persisted Elsewhere, mostly dry weather and fluctuating temperatures affected the West.
Light precipitation was confined to the northern tier of the region, from the Pacific Northwest to the northern Rockies. Breezy conditions hampered wildfire containment efforts, especially in the Four Corners States, while late-week heat promoted crop development in California.
