In the West, several large wildfires remain active in Arizona, Colorado, and New Mexico, and the risk of additional fires remains high in the Four Corners States. In contrast, cool showery weather in northern California and the Northwest is slowing crop development but boosting topsoil moisture.
On the Plains, very warm weather is promoting crop development. Thunderstorms, primarily confined to the northern half of the region, are heaviest in Nebraska and neighboring states. Winter wheat harvesting continues to advance northward across the southern Plains.
In the Corn Belt, thunderstorms are slowing late-season soybean planting, especially in Iowa and northern Illinois. Elsewhere in the Midwest, warm weather favors corn and soybean growth.
In the South, warm conditions and isolated showers are maintaining generally favorable conditions for pastures and summer crops. On June 16, at least three-quarters of the pastures were rated in good to excellent condition in all Southeastern States except Kentucky (74% good to excellent), Louisiana (63%), and Florida (59%).
Outlook: For the remainder of the week, scattered showers and thunderstorms will occur across the northern and eastern U.S. Some of the heaviest rain can be expected from near the Iowa-Minnesota-Wisconsin triple point into New England, where 5-day totals could reach 2 to 4 inches. One- to 2-inch totals can be expected in the Southeast and Pacific Northwest, but little or no rain will fall from southern California to the southern half of the Plains. Meanwhile, most of the U.S. will experience above-normal temperatures during the next several days, except for an early-week chill in the Far West. Toward week’s end, cooler air will overspread the Midwest. The NWS 6- to 10- day outlook for June 29 – July 3 calls for above-normal temperatures from the Pacific Coast to the High Plains and along the Atlantic Seaboard, while cooler-than-normal conditions will prevail from the central Gulf Coast region northward into the Great Lakes States. Meanwhile, below-normal rainfall in the middle and lower Rio Grande Valley and from the Pacific Coast into the western Corn Belt will contrast with wetter-than-normal weather across the eastern one-third of the U.S. and southern portions of the Rockies and Plains.
