"April's Severe Weather Threat: Tornadoes, Thunderstorms, and Flooding Across the US"

A major storm system is set to sweep across the United States, bringing severe weather, snow, and flooding. Starting in California, it has already caused thunderstorms, flooding, and heavy mountain snow. As it moves eastward, it is expected to bring severe thunderstorms and tornadoes to the Central and Eastern states, with a potential for flooding rain. New England may also experience an intense late-season snowstorm. The storm's impact is attributed to the clash of air masses as winter cold lingers and seasonal warmth increases.
