Nearly ideal weather across the Corn Belt

Across the Corn Belt, cool, mostly dry weather is nearly ideal for pastures and summer crops, as well as soft red winter wheat harvesting. On July 6, at least half of the pastures were rated in good to excellent condition in every Midwestern State, ranging from 52% in Nebraska to 91% in Wisconsin.

On the Plains, thundershowers stretch across Oklahoma. The showers separate warm, humid conditions in Texas from cool, dry weather farther north, where winter wheat maturation and harvesting continues. On the northern Plains, rangeland and pastures were rated more than 80% good to excellent on July 6 in the Dakotas.

In the South, scattered showers and thunderstorms stretch from Virginia to Arkansas. Rain is still needed in parts of the southern Atlantic States, where topsoil moisture has been diminishing and is currently rated 60% very short to short in South Carolina.

In the West, widely scattered showers in the Great Basin and Four Corners States are heaviest in parts of southern Arizona. Meanwhile, hot, dry conditions persist in northern California and the Northwest. On July 6, topsoil moisture was rated 63% very short to short in Washington.

A much cooler pattern ahead for the Heartland

A push of cool air across the Plains and Midwest will maintain generally favorable conditions for summer crops, especially those moving through the temperature- and moisture-sensitive reproductive stage of development. By week’s end, however, heat will return to areas from the southern Plains into the Southeast. Meanwhile, persistently hot, mostly dry weather will continue to dominate the Northwest. In the Southwest, monsoon showers will help to suppress temperatures and provided some drought relief. Five-day rainfall totals could reach 1 to 2 inches, with locally higher amounts, in parts of the Southeast and from the Four Corners States northeastward across portions of the northern and central Plains and the Midwest. In contrast, little or no rain will fall across the south-central U.S., including Texas.

Looking ahead, the 6- to 10-day outlook calls for below-normal temperatures across the northern and central Plains and Midwest, while hotter-than-normal weather will cover the West and Deep South. Meanwhile, near- to above-normal rainfall across the majority of the U.S. will contrast with drier-than-normal conditions in the western Gulf Coast region and from the Pacific Northwest into the upper Midwest.

Winter wheat harvest a bit delayed

Across the Corn Belt, cool, dry, breezy weather prevails across the upper Midwest. Meanwhile, showers and thunderstorms stretch from Michigan to southern Missouri, in conjunction with a cold front. The rain is maintaining abundant moisture reserves for corn and soybeans, but hampering winter wheat harvesting.

On the Plains, scattered showers are affecting central portions of the region, mainly Kansas. Elsewhere, cool, dry weather on the northern Plains contrasts with lingering heat in Texas. On July 6, the winter wheat harvest ranged from 13 to 18 percentage points behind the 5-year average pace in Colorado, Kansas, and Nebraska.

In the South, showers and thunderstorms in advance of a cold front are pushing across portions of Kentucky, Tennessee, and Arkansas. Elsewhere, hot, humid weather prevails. Most pastures and crops remain well-watered, but short-term dryness has begun to develop in parts of the Southeast. On July 6, at least half of the pastures were rated in good to excellent condition in every Southeastern State except South Carolina (40%).

In the West, hot, dry weather in California and the Northwest contrasts with widely scattered showers in the Great Basin and the Southwest. Crop conditions have deteriorated in parts of the Northwest, with more than one-quarter of Washington’s winter wheat (28%) and spring wheat (29%) rated very poor to poor on July 6.

A cool-off for the Heartland

Hot, mostly dry weather will persist through week’s end in California and the Northwest, but cooler air will briefly overspread the Plains and Midwest. The push of cool air will be preceded by widespread showers and thunderstorms, mainly across the South and East. During the second half of the week, showers and thunderstorms will accompany a return to warm weather across the northern Plains and parts of the Midwest. Elsewhere, monsoon showers will continue in the Four Corners States, but little or no rain will fall across Texas. Five-day rainfall amounts could reach 1 to 3 inches in the Southeast and Southwest, while parts of the upper Midwest may receive an inch or more.

Looking ahead, the 6- to 10-day outlook calls for below-normal temperatures across the northern and central Plains and Midwest, while hotter-than-normal weather will cover the West and Deep South.  Meanwhile, near- to above-normal rainfall across the majority of the U.S. will contrast with drier-than-normal conditions in the western Gulf Coast region and from the Pacific Northwest into the upper Midwest.

A wet pattern for parts of the Corn Belt

Very warm weather will dominate many areas of the country for the remainder of the week, although a modest surge of cool air will arrive across the Plains and Midwest. Below-normal temperatures will also affect portions of the Southwest due to cloudiness and showers associated with monsoon onset. In contrast, heat will be especially persistent in the Northwest. Meanwhile, showers in the vicinity of a cold front could result in 1- to 3-inch rainfall totals, with locally higher amounts, across the eastern half of the U.S. Similar amounts can be expected in the Southwest, but little or no rain will fall through week’s end across California, the High Plains, and the Northwest.

Looking ahead, the 6- to 10-day outlook calls for warmer-than-normal weather nationwide, except for near-normal temperatures in the Midwestern and Mid-Atlantic States. Meanwhile, wetter-than-normal conditions in the Four Corners region and east of the Mississippi River will contrast with near- to below-normal rainfall across the remainder of the country.

Near ideal weather pattern across most of the Corn Belt

Across the Corn Belt, scattered showers and thunderstorms accompany a push of slightly cooler air. Hot weather lingers, however, across the southern Corn Belt. Overall growing conditions remain mostly favorable for Midwestern corn and soybeans. From New Boston, Illinois, downstream to Burlington, Iowa, the Mississippi River recently crested at its third-highest level on record, behind 1993 and 2008.

On the Plains, widely scattered showers and thunderstorms from Kansas northward are causing minor delays in winter wheat harvesting and other fieldwork. Topsoil moisture remains mostly favorable for pastures, rangeland, and summer crops, although hot, dry weather has recently returned to the southern High Plains.

In the South, hot, humid, mostly dry weather favors fieldwork and a rapid pace of summer crop development. Scattered showers are mostly confined to Florida’s peninsula.

In the West, monsoon showers are providing limited drought relief, mainly in Arizona and the southern Great Basin. In contrast, hot, dry weather is maintaining heavy irrigation demands and stressing rangeland, pastures, and rain-fed crops in California and the Northwest.

Seasonal early-July weather for the Plains, Midwest

The development of the season’s first Atlantic Basin tropical storm appears likely this week just east of the southern Atlantic Coast, with uncertain impacts on coastal weather as the holiday weekend approaches. Meanwhile, cooler, drier air will briefly overspread the Plains and Midwest in the wake of a series of cold fronts. Before the fronts clear the Plains and Midwest, however, additional rainfall totals of 1 to 3 inches can be expected in parts of the northern and western Corn Belt. Showers will linger, possibly into the 4th of July weekend, across portions of the South and the Atlantic Coast States. During the weekend, scattered showers will return to the nation’s mid-section, mainly across the northern Plains and upper Midwest. Elsewhere, mostly dry weather will prevail west of the Rockies.

Looking ahead, the 6- to 10-day outlook calls for above-normal temperatures across the northern Plains, West, and Southeast, while cooler-than-normal conditions will be limited to an area stretching from eastern Texas to the Great Lakes States. Meanwhile, below-normal rainfall across the Northeast, Northwest, and northern Plains will contrast with wetter-than-normal weather in the Southwest and Southeast.

Showers & t-storms march across the Heartland

Across the Corn Belt, a band of scattered showers and thunderstorms—stretching from eastern Nebraska to Indiana—bisects the region. Cooler air is beginning to overspread the upper Midwest, but warm weather is promoting a rapid crop development pace across the remainder of the Corn Belt. In a few upper Midwestern locations, including Sioux Falls, South Dakota, the wettest June (and month) on record is coming to a close.

On the Plains, separate areas of showers are affecting northern and central portions of the region. The rain is slowing fieldwork in eastern Nebraska. However, conditions remain generally favorable for summer crops, despite pockets of excessive soil moisture.

In the South, tropical storm formation appears to be imminent east of the Florida coast. Elsewhere, warm, humid weather prevails. Widely scattered showers are most numerous in the southern Appalachians.

In the West, cool weather across the northern Intermountain region contrasts with hot conditions in the Southwest and portions of the Pacific Coast States. In California and the Desert Southwest, heat is maintaining heavy irrigation demands.

Water-logged fields across parts of the Corn Belt

Across the Corn Belt, drier weather has returned to western portions of the region, where 7-day rainfall of 4 to locally more than 12 inches has resulted in major river flooding and water-logged fields. Showers and thunderstorms in the Ohio Valley are improving soil moisture for corn and soybeans.

On the Plains, showers and thunderstorms have expanded over Texas, Oklahoma, Kansas, and southeastern Colorado, providing much-needed drought relief but arriving too late for maturing winter wheat. Showers have been slow to exit the north, though somewhat drier conditions are enabling fieldwork to resume.

In the South, heavy downpours in southern Texas are easing drought but causing localized flooding. Mostly dry, hot weather elsewhere is promoting winter wheat harvesting and other seasonal fieldwork after recent rain-induced delays, though seasonal showers continue in Florida.

In the West, isolated light showers are falling in the Northwest, while sunny, seasonably warm weather elsewhere is promoting fieldwork and crop development but maintaining or worsening drought.

A drier pattern next week for parts of the Heartland

A stationary frontal boundary stretching from the western Corn Belt into the southern Mid-Atlantic will separate chilly conditions in the Northeast from heat and humidity over much of the south. Locally heavy rain will persist along the front, with totals of 2 to 4 inches (locally more) possible across the central Plains and Midwest. Meanwhile, heat and humidity coupled with a series of weak disturbances will lead to scattered but potentially heavy downpours from the southern High Plains and southern Texas into the Southeast. Farther north, a slow-moving storm in southern Canada will produce scattered showers over the northern Plains and Upper Midwest. Out west, showers will diminish in the Northwest as dry, increasingly hot weather gradually returns from the Rockies to the Pacific Coast.

Looking ahead, the 6- to 10-day outlook calls for above-normal rainfall in the Northwest and from the southeastern Plains to the central Atlantic Coast. Conversely, drier-than-normal conditions will prevail in the Four Corners region and from the northern Plains into the Upper Midwest. Above-normal temperatures are expected over the northern Plains and much of the western U.S. as well as the Southeast and southern Mid-Atlantic, while cooler-than-normal weather develops from Texas into the Great Lakes region.
