Downpours challenged many of the nation’s farmers this month, while cool, stormy weather often kept spring revelers indoors or well bundled. Cool conditions were especially prevalent in the north-central United States, although rainfall provided drought relief on the northern High Plains.

Meanwhile, spotty rains kept the southeastern drought at bay—at least temporarily—despite underlying long-term rainfall deficits. Elsewhere, rapidly fluctuating conditions affected the West, where unusually heavy precipitation followed a mid-month heat wave. Western water-supply prospects for the spring and summer runoff season remained mostly favorable, except in California and the Great Basin.

Elsewhere, near-normal temperatures prevailed in the Southeast, while the mid-May heat wave boosted monthly readings slightly above normal in the
