If there ever was a year famous in New England weather annals, it is that of 1816. And in that year on this date, the final straw came in the form of severe cold, lasting from the 26th through the 29th, with frost throughout New England. The cold was combined with a very dry northwest wind, which meant there was not enough moisture for frost to form, but the sub-freezing temperatures severely damaged vegetation, turning it black, and hence the term a “black frost”.
