Meteorological events that happened on May 12th:

1760

Ben Franklin was the first person to identify nor'easters. In a letter on this date, Franklin described an experience that happened to him in November 1743 when storm clouds in Philadelphia blocked his view of an eclipse. Franklin assumed that the storm had blown in from the northeast because the surface winds at his location were from that direction. He was puzzled to find out later that his brother had viewed the eclipse with no problems and that the storm had arrived in Boston four hours later. The information caused Franklin to correctly surmise that the storm had moved from southwest to northeast.
