Low pressure to the west of the forecast area and a weak southerly flow aloft set the stage for a major outbreak of severe thunderstorms which produced numerous reports of large hail in central and southern New Hampshire. Some of the larger storms also brought down trees and power lines. In addition, these slow moving storms produced very heavy rainfall and resulted in several reports of flash flooding.
