USDA's Joint Ag Weather Facility says in the Corn Belt, shower activity is limited to the far upper Midwest, including parts of Minnesota and North Dakota. Heat remains most intense across the southwestern half of the Corn Belt, where today’s highs will range from 90°F to 100°F, USDA details. Midwestern heat and dryness are having an a diverse effect on filling summer crops, USDA continues.
In the West, USDA says showers are affecting parts of Arizona and New Mexico. "The showers are occurring within a pool of tropical moisture that includes Tropical Storm Juliette, currently moving northwestward along the west coast of Baja California," USDA explains. Elsewhere, beneficial showers continue in the Pacific Northwest, while hot, dry weather is maintaining the threat of wildfire development or expansion in northern California and the interior Northwest, according to USDA.
On the Plains, USDA reports rainfall is confined to North Dakota. "Elsewhere, hot, dry weather continues to increase stress on rangeland, pastures, and immature summer crops, especially in areas with limited soil moisture," USDA continues. Today’s high temperatures will approach or reach 100°F in many locations, USDA elaborates.
In the South, USDA says dry weather is promoting a gradual return to fieldwork and benefiting immature summer crops in previously waterlogged Southeastern areas. "Meanwhile, hot, dry weather in the Mississippi Delta favors summer crop maturation and fieldwork, including initial rice harvest efforts," USDA explains.
In its outlook, USDA says during the next few days, showers will become more numerous across the East and Midwest. "Five-day rainfall totals could reach 1 to 3 inches from the upper Mississippi Valley to New England, while 1- to 2-inch amounts will be common in the Southeast, Southwest, and Pacific Northwest," USDA details. However, mostly dry weather will persist across the nation’s mid-section, including the southwestern Corn Belt, USDA adds. In addition, heat will continue for several more days across the Plains and Midwest, although cooler air will arrive in the latter region early next week, according to USDA.
