Across the Corn Belt, showers are developing across the upper Midwest, where more than three-quarters of the pastures were rated in very poor to poor condition on September 9 in Nebraska (97% very poor to poor), Iowa (77%), and South Dakota (76%). The rain is causing only minor fieldwork delays.
On the Plains, cool weather is returning to northern areas. Meanwhile, highly beneficial showers in the vicinity of a cold front stretch from the central High Plains to the middle Missouri Valley. Winter wheat planting is off to a slow start, behind the 5-year average in all seven major production states on the Plains. On September 9, planting progress was more 5 percentage points behind the average in Colorado (0% planted versus the average of 13%), Nebraska (8 vs. 16%), and South Dakota (8 vs. 14%).
In the South, warm, dry weather prevails, except for isolated showers across Florida’s peninsula and along the Gulf Coast. Harvest activities are ongoing for a variety of summer crops.
In the West, scattered showers linger, mainly in the Four Corners States. Meanwhile, dry weather is promoting Northwestern small grain planting. On September 9, Washington led the nation with 31% of its winter wheat planted, slightly ahead of the 5-year average of 30%.
The interaction between a cold front and a late-season monsoon surge will result in showers and thunderstorms across the central and southern Plains and parts of the Midwest. Showers will also develop in the Gulf Coast region, but dry weather will prevail through week’s end from the Pacific Coast to the northern Plains. A brief cool spell will trail the cold front, but temperatures will quickly rebound to above-normal levels late in the week across the northern Plains and much of the West.
Looking ahead, the 6- to 10-day outlook calls for below-normal temperatures across the Plains, Midwest, and Mid-South, while warmer-than-normal weather will be confined to the Atlantic Seaboard and areas west of the Rockies. Meanwhile, above-normal rainfall east of the Mississippi River and across southern portions of the Rockies and Plains will contrast with drier-than-normal conditions in much of the West and across the northern half of the Plains.
