Great Barrington, MA F4 Tornado of May 29, 1995

Berkshire County

Figure 1 depicts the surface observations at 8:00 am EDT, which shows a warm front moving north across the northeast United States and a cold front moving across Lake Ontario. The cold front moved east throughout the day on May 29th, triggering thunderstorms across New York.

Figure 3 shows Doppler radar taken from Bosart, Seimon, LaPenta and Dickinson (2006), which shows a storm in New York intensifying as it heads toward Great Berrington in Massachusetts. This storm would become responsible for spawning a long-track F4 tornado as it continues to intensifying moving east.

The Great Berrington, MA F4 tornado of May 29, 1995 impacted Berkshire County in Massachusetts. According to NOAA (2019), the F4 tornado caused 3 fatalities, 24 injuries and $250 dollars in property damage. The tornado touched down 1 mile southeast of North Egremont at 7:06 pm EDT. The tornado travelled for approximately 14 miles and had a maximum width of 1100 yards (Bosart & al., 2006). Bosart and al. (2006) suggest that the path length of this tornado may have been up to 50 km (31 miles), but that damage survey is very difficult throughout the terrain of southwestern Massachusetts. The official end of this tornado was 1.5 miles southwest of West Otis (NOAA, 2020).
