An offshore storm will cause clouds and showers to keep the Mid-Atlantic Coast damp on Monday. Lingering moisture will help fuel showers and thunderstorms across the central and southern Appalachians. The afternoon will be the most active time of the day. A shower or thunderstorm will dot a few communities in the Southeast, but most of the region will be dry.

The rest of the Northeast will dry out as high pressure builds overhead, bringing sunshine across the Great Lakes.

On the backside of this high pressure, warmth will build across the Plains with temperatures set to rise 10 to 20 degrees above normal. The warmth will help create a few severe thunderstorms across the northern High Plains during the afternoon and evening hours. The strongest of these thunderstorms have the potential to produce damaging winds, hail and frequent lightning. Less intense thunderstorms will rattle the northern Rockies, and anyone outdoors should remain vigilant of the risk of lightning strikes.

The West will otherwise be dry as the Southwest desert remains hot. Air flowing in from the Pacific Ocean will keep the western coastal communities on the cool side.

FOCUS: Strong Thunderstorms in the High Plains

A few strong thunderstorms will develop across parts of the High Plains on Monday afternoon. Areas from northeast Colorado into eastern Montana and southwest North Dakota will be at risk. These storms can produce locally damaging winds, hail and downpours.
