In the West, above-normal temperatures continue to expand eastward, and have reached the northern Rockies. In California and the Desert Southwest, hot, dry weather is promoting fieldwork and crop development.

On the Plains, unusually cool conditions prevail, except for lingering heat across the southern two-thirds of Texas. Showers and thunderstorms remain active on the central Plains, primarily north of the front separating cool from hot air. Farther north, dry weather is gradually returning to the northern Plains, although most fields remain too wet to resume planting activities.

In the Corn Belt, any remaining corn and soybean planting activities are proceeding in eastern portions of the region. Meanwhile, cool weather and scattered showers are maintaining a sluggish pace of fieldwork in the northern and western Corn Belt. In addition, a significant river flood event continues to threaten levees and disrupt barge traffic in the middle Mississippi and lower Missouri Valleys.

In the South, warm, dry weather is promoting fieldwork, winter wheat maturation, and summer crop growth in most areas. However, a low-pressure system over the Gulf of Mexico is helping to spark an increase in the coverage and intensity of shower activity in the lower Southeast, including parts of Florida.

Outlook: Rain will end later today across the Plains, except for some lingering showers and thunderstorms in Oklahoma and environs. Meanwhile, showers will continue to spread eastward across the Corn Belt. Late in the week, a cold front moving into the East will interact with a low-pressure system moving northeastward from the Gulf of Mexico. As a result, 5-day rainfall totals could reach 2 to 5 inches in the East, particularly in the Atlantic coastal plain. During the weekend, locally heavy showers and thunderstorms may return to the Upper Midwest, while hot, dry conditions will persist west of the Rockies. The NWS 6- to 10-day outlook for June 10-14 calls for near- to below-normal temperatures across the eastern half of the U.S., while warmer-than-normal weather will prevail in most areas from the High Plains westward. Meanwhile, near- to below-normal precipitation across the majority of the nation will contrast with wetter-than-normal conditions in the lower Great Lakes region and the middle and northern Atlantic States.
