In the West, warmth is returning to the Pacific Coast States, but chilly conditions linger across the northern Rockies and northern Intermountain region. Throughout the West, dry weather favors fieldwork.
On the Plains, cooler-than-normal weather prevails. Showers dot the northern Plains, but rain is still needed on the central and southern Plains to prevent further stress on pastures and rain-fed summer crops.
In the Corn Belt, showers and thunderstorms are maintaining favorable growing conditions across the upper Midwest. In stark contrast, more than one-tenth of both corn and soybeans were rated very poor to poor on June 17 in Illinois (13 and 14% very poor to poor, respectively, for corn and soybeans), Indiana (24 and 26%), Michigan (12 and 14%), Missouri (21 and 29%), and Ohio (11 and 15%).
In the South, showers are confined to southern portions of Texas and Florida. Elsewhere, very warm, dry weather prevails. Some of the region’s most significant drought concerns exist across the Mid-South, where 56% of the pastures in Arkansas were rated in very poor to poor condition on June 17.
Outlook: For the remainder of today, scattered thunderstorms in the vicinity of a cold front will affect the Plains and western Corn Belt. In advance of the front’s passage, extremely hot, humid weather will prevail across much of the Midwest, South, and East. However, the front will move across the Midwest and Northeast by late in the week, bringing to an end the early-season heat wave. Heat will persist, however, across the South and return to the High Plains during the weekend. Elsewhere, scattered showers will affect southern Texas and the Pacific Northwest, while torrential downpours will accompany a potential tropical system across southern Florida. The NWS 6- to 10- day outlook for June 25-29 calls for near- to above-normal temperatures and near- to below-normal rainfall across the majority of the U.S. Cooler-than-normal conditions will be limited to the lower Great Lakes and Northeastern States and areas along the Pacific Coast, while wetter-than-normal weather will be confined to Florida’s peninsula, New England, the Four Corners region, and portions of Montana and the Pacific Northwest.
