For the week, USDA reports 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.
The NWS 6- to 10-day outlook for May 26-30 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.
Here’s a breakdown of weather forecasts, by region:
- In the West, warm, dry weather prevails, except for a return to cool, showery conditions in the Pacific Northwest.
- 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 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 easternmost Corn Belt from slightly cooler, dry weather in the western Corn Belt.
- In the South, Tropical Storm Alberto – a very small system – is currently centered about 100 miles eastnortheast 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.
