An active pattern across the Corn Belt this week...
On the Plains, wet weather is returning to western and central Montana. Elsewhere across the nation’s midsection, warm, dry weather is promoting winter wheat planting and summer crop maturation and harvesting. On September 18, freezes ended the growing season—roughly on schedule—in the northeastern corner of Montana and approximately the western half of North Dakota.
Across the Corn Belt, cool weather across the northern tier of the region contrasts with warm conditions elsewhere. Mostly dry weather favors corn and soybean maturation and harvesting.
In the South, showers are confined to the western Gulf Coast region. Elsewhere, summer crop harvest activities are advancing under favorable conditions. However, pockets of drought persist from the lower Mississippi Valley into the middle and southern Atlantic States.
In the West, warm, dry weather prevails from inland sections of California into the Southwest. Meanwhile, cool weather and isolated showers are causing minor wheat planting delays in the Northwest.
For the remainder of the week, a pair of low-pressure systems will cross the North. Both systems will feature a trailing cold front, studded with scattered showers. The two-storm rainfall totals will be heaviest in the western Corn Belt and the upper Great Lakes region, where amounts could reach 2 to 4 inches.
Elsewhere, scattered showers will be mostly confined to the Four Corners States, southern portions of Texas and Florida, and the Pacific Northwest.
Although much of the U.S. will experience warmer-than-normal weather through the end of the week, cool conditions will be common across the North.
Looking ahead, the 6- to 10-day outlook calls for near- to above-normal temperatures nationwide, except for cooler-than-normal conditions in southern Texas and the southern Atlantic States. Meanwhile, near- to below-normal precipitation across the majority of the U.S. will contrast with wetter-than-normal weather in the Pacific Northwest, southern parts of Texas and Florida, and from the Great Lakes region into New England.
