Cooler, drier air settles into the Corn Belt

Cooler, drier air settles into the Corn Belt

Across the Corn Belt, scattered, generally beneficial showers are occurring in the vicinity of a cold front stretching southward from Michigan. The front separates warm, humid air in the eastern-most Corn Belt from slightly cooler, dry weather in the western Corn Belt.

On the Plains, lingering showers and thunderstorms are confined to portions of Oklahoma and northern Texas. Meanwhile, warm weather is returning to the northern Plains, following a recent period of highly beneficial rainfall.

In the South, Tropical Storm Alberto – a very small system – is currently centered about 100 miles east-northeast of St. Augustine, Florida, with minimal impacts on U.S. weather. Elsewhere, a few showers – not directly related to Alberto – are spreading inland across the southern Mid-Atlantic States, while beneficial rain associated with a cold front is falling in parts of the lower Mississippi Valley.

In the West, warm, dry weather prevails, except for a return to cool, showery conditions in the Pacific Northwest.

Tropical Storm Alberto will remain offshore, although the interaction between a marine air mass and an approaching cold front will generate showers and thunderstorms through mid-week in the middle and northern Atlantic States.

Meanwhile, widespread showers will accompany a surge of cool air from the Northwest to the upper Midwest. Farther south, however, mostly dry weather will prevail through week’s end from California into the south-central U.S.

Looking ahead, the 6- to 10-day outlook calls for above-normal temperatures across the eastern two-thirds of the U.S., while cooler-than-normal conditions will prevail in the West. Meanwhile, below-normal rainfall across the majority of the U.S. will contrast with wetter-than-normal weather from the Pacific Northwest to the upper Midwest.
