During the Blizzard of Feb. 8-9, 2013 there were reports of thunder and lightning amidst the heavy snowfall and high winds. The lightning detector on the roof of Ladd Observatory recorded a great deal of activity late Friday night into Saturday morning with the peak occurring just before midnight. Most of the strikes were along the southern coast of Rhode Island, but some were observed about 350 miles to the south over the ocean.
