Across the south-central United States, relentlessly hot, mostly dry weather maintained severe stress on pastures, rangeland, and rain-fed summer crops. Even some heavily irrigated crops on the southern Plains suffered under the spell of record-breaking heat and drought. Texas experienced its hottest June, breaking a 1953 record, and endured its driest June since 1934.
Farther north, however, cool, showery weather continued to plague the northern Plains and the Northwest, hampering crop development and late-season planting efforts. Flooding intensified along the Missouri River, as heavy rain falling on saturated soils combined with runoff from melting snow in the northern Rockies.
Meanwhile, much of the Corn Belt experienced improving conditions, following early-season planting delays. Across the previously waterlogged eastern Corn Belt and upper Midwest, producers were able to plant most of the remaining acreage intended for corn and soybeans. As the month progressed, warmer weather promoted Midwestern crop emergence and development.
Elsewhere, drought covered not only the southern Plains but also stretched from Arizona to the southern Atlantic Coast. Wildfires and poor crop conditions were obvious symptoms of the soil moisture shortages. Toward month's end, however, an increase in shower activity started to provide some Southeastern drought relief.
Monthly temperatures averaged as many as 5 degrees Fahrenheit below normal across the northern High Plains and parts of the West, but ranged from 5 to 10 degrees Fahrenheit above normal in much of the south-central United States.
