In the Corn Belt, scattered showers are confined to portions of the Great Lakes region. Elsewhere, dry weather and near-normal temperatures favor a push toward corn and soybean maturation. However, statewide crop development is running as much as 2 to 3 weeks behind schedule in states such as Indiana, where most planting occurred very late.
On the Plains, late-season warmth continues, especially across the southern half of the region, where Friday’s high temperatures will again approach or reach 100° in many locations. Winter wheat planting preparations continue on the southern Plains, where rain will be needed to ensure even emergence and proper autumn establishment once the crop has been planted. Elsewhere, a few rain showers are developing across the northern High Plains.
In the South, Category 1 Hurricane Dorian is making its closest pass to the U.S. mainland. Early Friday morning, Dorian was centered 10 miles west-southwest of Cape Hatteras, North Carolina, moving toward the northeast at 14 mph. Mid-Atlantic coastal impacts include heavy rain, high winds, and a 2- to 7-foot storm surge. Elsewhere in the South, very warm, dry weather remains nearly ideal for summer crop maturation and harvesting of crops such as corn and rice.
In the West, late-season warmth continues at most interior locations. However, beneficial showers have developed across the interior Northwest, where topsoil moisture on September 1 was rated at least one-half very short to short in Oregon (73%), Idaho (55%), Wyoming (53%), and Washington (50%).
For the remainder of Friday, impacts from Hurricane Dorian will gradually subside along the Mid-Atlantic Coast as the storm accelerates northeastward across the northwestern Atlantic Ocean. Meanwhile, the focus for heavy precipitation will shift to the Northwest, where 5-day totals could reach 1 to 3 inches or more. Similar totals can be expected across the northern Plains and the upper Midwest. Farther south, a late-season surge of monsoon-related moisture could lead to locally heavy showers in the central and southern Rockies and parts of the Southwest. Most of the remainder of the country, including California and a broad area stretching from the Gulf Coast to the Ohio Valley, will remain dry during the next 5 days. Although a weekend surge of cool air will engulf much of the northern and western U.S., major agricultural areas across the northern Plains and Midwest will not experience a freeze.
Looking ahead, the 6- to 10-day outlook calls for the likelihood of near- or above-normal temperatures and rainfall across most of the country. Cooler-than-normal conditions will be confined to New England and the northern Rockies, while drier-than-normal weather should be limited to parts of the southern Atlantic region and eastern Texas.
