USDA's Joint Ag Weather Facility says in the Corn Belt, cool weather continues to benefit reproductive to filling summer crops. Showers in the western Corn Belt are easing concerns over short-term dryness, USDA observes.
On the Plains, showers and thunderstorms along a stationary frontal boundary are providing drought relief from South Dakota into Kansas and Oklahoma, according to USDA. Below-normal temperatures over the northern Plains are contrasting with 100-degree heat across southern portions of the region.
In the West, a resumption of the monsoon is providing much-needed moisture to drought-stricken areas of the Four Corners region, USDA says. Showers have also returned to the Northwest, slowing winter wheat maturation and harvesting. Elsewhere, dry, cooler-than-normal weather is promoting summer crop development and fieldwork, USDA notes.
In the South, dry, increasingly warm weather is following yesterday’s rain. Soil moisture remains adequate to locally excessive for pastures and summer crops after a record-wet July in portions of the region, USDA states.
In its outlook USDA says, showers will accompany a cold front as it pushes slowly southeast across the eastern third of the nation over the weekend. Meanwhile, a stationary upper-air low in eastern Canada will maintain well-below-normal temperatures from the northern Plains into the Corn Belt and Northeast. In contrast, a ridge of high pressure will provide hot, dry weather across the southern Plains and western Delta, USDA states. Between these two air masses, a frontal boundary coupled with a series of weak disturbances will generate periods of rain (locally more than 2 inches) from the central Plains into the western and southern Corn Belt. Out west, monsoon showers will persist in eastern portions of the Four Corners region, while sunny skies and seasonably hot weather continue in California and the Great Basin, USDA says.
