USDA's Joint Ag Weather Facility says in the Corn Belt, highly beneficial showers are affecting both eastern and western portions of the region. "However, pockets of developing drought still exist, especially from Nebraska to Ohio, and more rain will soon be needed to maintain current crop conditions," USDA reports.
In the West, USDA explains warm weather is returning to the Pacific Coast states, but cool conditions linger farther inland. "Freeze warnings are in effect early today in parts of northern Nevada and western Colorado," USDA reports.
On the Plains, USDA explains unfavorably hot weather continues in much of western and central Texas, where Sunday's high temperatures generally ranged from 100 to 110°F. "Elsewhere, cool air continues to overspread the northern and central Plains, while a few rain showers linger across Montana," USDA adds.
In the South, USDA says weekend rainfall provided drought relief, mainly east of the Mississippi River. "Some of the heaviest rain fell in the eastern Gulf Coast region, including northern Florida and southern portions of Alabama and Mississippi," USDA explains. Currently, scattered showers continue across the Southeast, it continues.
In its outlook, USDA says a plume of moisture over the eastern U.S. will merge with a cold front currently crossing the western Corn Belt. "Rain will end by Wednesday in the Northeast but will linger for several days in the Southeast," according to USDA. Additional rainfall totals associated with merging weather systems could reach 1 to 2 inches, with locally higher amounts, across the South and East, USDA explains. Most of the Midwest will receive less than an inch of additional rainfall, USDA adds. "Late in the week, however, showers and thunderstorms will return to parts of the northern and central Plains and the upper Midwest," USDA reports. In contrast, USDA says dry weather will prevail through week’s end in the West, except along the Canadian border.
