In the West, markedly cooler air is overspreading the Pacific Coast States. In the Pacific Northwest, widespread rain showers accompany the turn toward cool weather. Meanwhile, warmth lingers across the central and southern Rockies and the Intermountain West.

On the Plains, hot weather is promoting winter wheat maturation. However, thunderstorms are causing minor wheat harvest disruptions on the southern Plains. Despite recent and ongoing showers, rain is still needed for pastures and rain-fed summer crops across portions of the central and southern Plains.

In the Corn Belt, chilly weather prevails in the lower Great Lakes region, where today’s high temperatures will remain largely below 70°F. Elsewhere, Midwestern pastures and summer crops are benefiting from recent topsoil moisture improvements, although pockets of unfavorable dryness persist.

In the South, a broken line of showers and thunderstorms stretches from South Carolina westward into eastern Oklahoma. The rain is providing much-needed moisture for pastures and summer crops, but unfavorably dry conditions persist across the Deep South, excluding the southern Atlantic region.

Outlook: During the next several days, a cold front will continue to settle across the South before stalling near the Gulf Coast. Five-day rainfall totals could reach 2 to 4 inches from Texas to the southern Atlantic States. Elsewhere, significant precipitation will be confined to the Northwest, where widespread, 1- to 3-inch totals will occur. Mostly dry weather will persist through week’s end in the Southwest and Midwest, although mid- to lateweek showers will affect parts of the northwestern Corn Belt. Elsewhere, cool conditions in the East and West will contrast with generally warmer-than-normal weather across the nation’s mid-section. The NWS 6- to 10-day outlook for June 9-13 calls for hotter- and drier-than-normal conditions across the majority of the U.S. Belownormal temperatures will be confined to the southern Atlantic region, the northern High Plains and the Northwest, while above-normal rainfall will be limited to southern Florida and the upper Midwest.
