But what is thundersnow? Meteorologist Dr. Greg Forbes says it is a snowstorm event in which thunder and lightning occur.
Thundersnow can be found where there is relatively strong instability and abundant moisture above the surface, such as above a warm front. Thundersnow is sometimes observed downstream of the Great Salt Lake and the Great Lakes during lake-effect snowstorms too.
Areas of New England reported nearly 2 feet of total snow over the weekend. Forecasters said another winter blast might hit the region midweek.
