In the West, cool weather lingers, especially across California and the Great Basin. Out-of-season showers continue to affect northern and central California, where crop development has been sluggish.

On the Plains, hot, dry weather prevails, except for a lingering chill along the Canadian border. Heat and drought are maintaining severe stress on pastures and rain-fed summer crops on the southern High Plains. In contrast, warm, dry weather favors crop development and late-season planting activities on the northern Plains.

In the Corn Belt, isolated thunderstorms are confined to the northern tier of the region. Heat is building into the southern and western Corn Belt, where today’s high temperatures will generally range from 90 to 100°F. The hot weather is promoting Midwestern summer crop development and late-season planting activities.

In the South
, record-setting heat continues to severely stress pastures and rain-fed summer crops across the Deep South. Continuing a recent trend, high  temperatures will exceed 100°F in portions of the western and central Gulf Coast States. Some locations, including Hattiesburg, Mississippi, have reached or exceeded 100°F every day this month.

Outlook: The last in a series of storms to affect California will drift northeastward, reaching the northern Plains on Tuesday. In the storm’s wake, California will experience a gradual warming trend. By week’s end, the storm system will arrive in eastern Canada, with a trailing cold front stretching from the Northeast to the central Plains. Showers and thunderstorms will accompany the front as it drifts southward. Five-day rainfall totals will locally reach 1 to 3 inches across the northern half of the U.S., but hot, mostly dry weather will persist across the southern one-third of the U.S. However, a tropical disturbance over the western Caribbean Sea may contribute to an increase in shower activity in Florida. The NWS 6- to 10-day outlook for June 11-15 calls for above-normal temperatures across much of the eastern half of the U.S., while cooler-than-normal weather will prevail in the West. Meanwhile, near- to above-normal precipitation across the majority of the U.S. will contrast with drier-than-normal conditions in the Pacific Northwest, Maine, and from southern California to the western Gulf Coast region.
