In the West, persistently cool weather across northern areas is hampering the development of winter wheat and spring-sown crops. Elsewhere, showers and thunderstorms are affecting the southern Rockies, while hot weather is promoting crop growth in southern California and the Desert Southwest.
On the Plains, locally severe thunderstorms across the southern half of the region are disrupting the winter wheat harvest but generally benefiting pastures and  summer crops. On the northern Plains, cool weather is limiting crop development, but showers are maintaining nearly ideal conditions for winter wheat and spring-sown small grains.

In the Corn Belt, cool but dry weather favors late-season planting activities. Across much of the Midwest, corn and soybeans are benefiting from abundant soil moisture reserves.

In the South, hot, mostly dry weather favors summer crop development and winter wheat maturation and harvesting. However, heat is also stressing reproductive summer crops, such as silking corn, from the Delta westward.

Outlook: For the remainder of the week, a series of disturbances will maintain unsettled conditions—including locally severe thunderstorms—across the northern half of the U.S., where rainfall could reach 2 to 4 inches. Less numerous thundershowers will affect areas from the southern Plains into the Southeast, while mostly dry
weather will prevail in the Southwest. Toward week’s end, a new surge of unusually cool air will engulf the West, while heat will briefly expand across the Midwest and into the East. The NWS 6- to 10-day outlook for June 12-16 calls for above-normal temperatures in the Pacific Coast States and the eastern one-third of the
U.S., while cooler-than-normal weather will prevail across the Intermountain West. Meanwhile, above-normal precipitation from the Pacific Northwest to the upper Great Lakes region will contrast with drier-than-normal conditions in most areas from the Southeast into New England.
