Thunderstorms continue in the vicinity of a cold front stretching from northern Michigan to Nebraska, producing showers across a wide swath of the Midwest, USDA's Joint Ag Weather Facility reported Friday. The front is producing unwanted rainfall in some areas, including southern Wisconsin and much of Iowa. However, showers have been beneficial in the northwestern Corn Belt, including Minnesota and the Dakotas, USDA said. Elsewhere in the U.S.:
- In the West, a band of monsoon moisture extends across the southern Rockies, where scattered showers are occurring. Dry weather elsewhere in the region favors fieldwork and crop development, although rain is needed for filling small grains in the Northwest.
- On the Plains, widely scattered showers are causing only minor disruptions in fieldwork, such as winter wheat harvesting, which is advancing northward from Colorado and Nebraska. Soil moisture levels remain highly variable, with a major drought still affecting parts of the central and southern High Plains.
- In the South, a weak low-pressure system continues to lurk near the southern Atlantic Coast, maintaining showery conditions. Elsewhere, hot, dry weather is bringing a return of stressful conditions for pastures and rain-fed summer crops, following last week's beneficial showers.
Near-term Outlook: During the next several days, locally heavy rainfall will continue in the vicinity of a slow-moving frontal boundary. As much as 2 to 3 inches of additional rain may fall from the east-central Plains northeastward into Michigan and New England. Late in the weekend, drier weather will return to the Midwest, while scattered showers will develop across the remainder of the eastern one-third of the U.S. Farther west, monsoon thundershowers will pepper the Four Corners region. Elsewhere, dry weather will prevail into early next week in much of California, the Northwest, and the south-central U.S., but locally heavy showers associated with a low-pressure system will linger along the southern Atlantic Coast.
Extended Outlook: The National Weather Service 6- to 10-day outlook for July 23-27 calls for hotter- and drier-than-normal weather across the majority of the U.S. Cooler-than-normal weather will be limited to Florida's peninsula, southern Texas, and the Pacific Northwest, while wetter-than-normal conditions will be confined to the Gulf and southern Atlantic Coast regions and parts of New England, the northern Plains, and the Pacific Northwest.
