In the West, rain and snow showers linger across northern areas, including the northern Rockies and the Pacific Northwest. Dry conditions prevail elsewhere, although cool weather continues to hamper crop development. In drought-affected areas of the Southwest, wildfire activity remains a significant threat.
On the Plains, wet weather is returning to the north, renewing fieldwork delays. By June 5, only 73 and 69% of the spring wheat had been planted in Montana and North Dakota, respectively. Meanwhile, hot, dry weather prevails on the central and southern Plains. Pastures and rain-fed summer crops on the southern High Plains remain severely stressed by drought.
In the Corn Belt, very warm, dry weather in most areas continues to support late-season planting efforts. Ohio remains in last place among the major corn production states, with 58% of its crop planted by June 5. On the same date, soybean planting had not surpassed the half-way mark among the following Midwestern States: Michigan (50%), Indiana (49%), North Dakota (47%), Kentucky (40%), and Ohio (26%).
In the South, isolated thundershowers in the vicinity of the Gulf Coast are providing only localized relief from heat and drought. Pastures and rain-fed summer crops are in need of cooler weather and widespread rainfall.
Outlook: A storm over the northern Plains will drift eastward, reaching the Great Lakes region by mid-week. Showers will develop along the storm’s trailing cold front, which by week’s end will stretch from the Northeast to the central Plains. Rainfall associated with the storm could reach 1 to 3 inches, with locally higher amounts, across the northern half of the U.S. However, hot, mostly dry weather will persist across the South. In the southern Atlantic States, however, tropical showers will increase in conjunction with a low-pressure system drifting northward from the Caribbean Sea. The NWS 6- to 10-day outlook for June 12-16 calls for below-normal temperatures from California into the Southwest, while hotter-than-normal weather will prevail from the southern Plains into the Southeastern and Mid-Atlantic States. Meanwhile, near- to above-normal rainfall across the majority of the U.S. will contrast with drier-than-normal conditions from the Pacific Coast States into the south-central U.S.
