Marginally severe thunderstorms are possible on Tuesday along the Eastern Seaboard.
Building high pressure on Tuesday over the Northern Plains and Upper Midwest regions will maintain the eastward progression of Monday’s cold front. The front should reach the Eastern Seaboard by midday while a surface low skirts across the Northeast. Showers and thunderstorms are a good bet from the Southeast region northward into New England. A few strong thunderstorms will be possible across a broad region while the axis of an eastern trough pivots through the Ohio Valley. Expect a primary risk for isolated winds gusting in excess of 45 mph.
