This Date in Weather History

1987 - Thunderstorms over the San Joaquin Valley of California produced three-quarters of an inch of rain in thirty minutes at Placerville, and caused numerous power outages due to lightning. Rain began to diminish in the northeastern U.S., but some flooding continued in Vermont, eastern New York and northern New Jersey. One inch rains in Vermont clogged culverts and sewers with fallen leaves, resulting in erosion of dirt roads.
