Heat, humidity & periodic rains for the Holiday Weekend

Heat, humidity & periodic rains for the Holiday Weekend

Across the Corn Belt, showers are benefiting filling corn and soybeans in western and northern portions of the region. In contrast, dry, hot weather across the southern Corn Belt is hastening summer crop maturation.

On the Plains, showers have returned to northern portions of the region, slowing spring wheat harvesting following a favorable week for fieldwork. Showers across the central and southern Plains are easing drought and improving soil moisture for winter wheat planting and establishment.

In the South, showers linger in southern Florida, while a disturbance continues to produce locally heavy downpours along the western Gulf Coast. Elsewhere, hot, dry weather favors crop maturation and fieldwork, including sorghum, rice, and corn harvesting.

In the West, dry, increasingly hot weather has supplanted monsoon showers in the Four Corners States. Meanwhile, persistent heat and dryness in the Northwest and northern California is promoting fieldwork but heightening irrigation demands and exacerbating drought impacts.

High pressure will slide off the Atlantic Coast, allowing heat and humidity to build east of the Mississippi, accompanied by afternoon showers and thunderstorms. Meanwhile, an upper-air disturbance will produce a more concentrated area of rainfall from the Midwest into the Northeast. Another area of low pressure and its associated cold front will generate showers in northern portions of the Rockies and Plains, and renew the risk for heavy rain in the northern and western Corn Belt by early next week. Farther south, a nearly-stationary disturbance in the western Gulf will trigger locally heavy downpours in southern Texas, but tropical storm development is not expected. Out west, dry, hot weather will replace recent rainfall in the Great Basin and Rockies, while heat and dryness will prevail in drought-afflicted California, Oregon, and central Washington.

Looking ahead, the 6- to 10-day outlook calls for near- to above-normal temperatures across much of the contiguous U.S., except for cooler-than-normal conditions over the northwestern quarter of the nation. Meanwhile, above-normal rainfall over the central and eastern U.S. — except for New England — will contrast with drier-than-normal weather from the Pacific Northwest and Great Basin southeastward into the Four Corners and western Texas.
