Severe weather, flooding threat on at least four storm fronts

Thunderstorms will span three-quarters of the nation on Tuesday, extending from both the Southwest and the northern Rockies and the West, across the South and to the northern tip of Maine, according to the latest forecast by the National Weather Service (NWS).
