Heat wave covers much of the Heartland
Across the Corn Belt, showers and thunderstorms are rumbling across the northern tier of Midwestern States. Farther south, weekend showers provided drought-stressed corn and soybeans with much-needed moisture, although soil moisture reserves remain limited across much of the southern and eastern Corn Belt.
On the Plains, cool weather is limited to portions of Montana and North Dakota. In contrast, Monday’s high temperatures will approach, reach, or exceed 100°F on the central and southern High Plains. In addition, drought is adversely affecting some pastures and rain-fed summer crops on the central and southern Plains.
In the South, summer crops and pastures continue to benefit from recent topsoil moisture improvements. However, not all of the rain has been equally distributed; significant drought persists in several regions, including much of the Mid-South and the northern Mississippi Delta.
In the West, scattered showers are confined to the northern tier of the region. Cool weather is limiting crop development in coastal California and from the Pacific Northwest to the northern Rockies, while above normal temperatures cover the remainder of the region.
During the next few days, heat will shift northeastward from the Southwest and the central and southern High Plains, eventually reaching the Northeast. Meanwhile, the Northwest will experience a rapid mid-week warming trend.
Significant precipitation will be confined to just a few areas, including southern Florida, the western Gulf Coast region, and the nation’s northern tier as far east as the Great Lakes region. Five-day rainfall totals could reach 2 to 4 inches or more in the upper Midwest. However, a broad area from California into the Southeast will remain dry.
Looking ahead, the 6- to 10-day outlook calls for hotter- and drier-than-normal weather nearly nationwide. Below-normal temperatures will be confined to the Pacific Coast States and areas from the lower Great Lakes region into the Northeast, while above-normal rainfall will be limited to the southern Atlantic States, parts of New England, and the nation’s northern tier from the Pacific Northwest to North Dakota.
