Across the Corn Belt, rain associated with Tropical Depression Barry is edging into southern parts of Illinois and Missouri. Meanwhile, showers in advance of an approaching cold front stretch from the upper Great Lakes region into Nebraska. Little rain has fallen so far in July across the southern and eastern Corn Belt, leaving some previously saturated soils crusted and compacted—to the detriment of late-planted corn and soybeans.
On the Plains, mostly dry weather from Kansas southward favors winter wheat harvesting and summer crop development. Meanwhile, widely scattered showers dot the northern Plains.
In the South, Tropical Depression Barry is moving slowly northward through Arkansas, while rain has spread as far north as southeastern Missouri. Early Monday, some of the most intense rain bands are causing flash flooding in parts of Louisiana and Mississippi, although overall storm impacts have been relatively minor. Elsewhere, hot, humid weather prevails in the southern Atlantic States.
In the West, cool weather and scattered showers stretch from the Pacific Northwest to the northern Rockies. The Northwestern showers are locally boosting topsoil moisture and benefiting spring-sown small grains. In contrast, a Southwestern heat wave will result in Monday’s high temperatures climbing as high as 120°.
The remnants of Barry will drift northeastward and weaken but remain a focus for heavy showers. Five-day rainfall totals could reach 2 to 4 inches or more from the mid-South into the Northeast. Meanwhile, a pair of cold fronts will cross the northern U.S., sparking scattered showers. Some of the heaviest rain, locally 1 to 3 inches or more, will fall across the upper Great Lakes States. In contrast, mostly dry weather will prevail through week’s end from California to the central and southern Plains, except for isolated Southwestern showers. Elsewhere, building heat will affect much of the central and eastern U.S. during the mid- to late-week period.
Looking ahead, the 6- to 10-day outlook calls for near- or above-normal temperatures nationwide, except for cooler-than-normal conditions in southern California and parts of the Northwest. Meanwhile, near- or below-normal rainfall across most of the country should contrast with wetter-than-normal weather in the central Gulf Coast region, the northern Plains, and the Desert Southwest.
