Northampton, MA F2 Tornado of August 14, 1958

Hampshire County

Figure 1 depicts the surface observations at 2:00 am EDT, which shows a cold front across Massachusetts and an stationary front across the northeast United States. The cold front likely became near-stationary throughout the day and triggered thunderstorms in the early evening hours (possibly aided by sea-breeze boundaries), which ultimately led to this tornado.
