HISTORIC WEATHER EVENTS
...1835...
New England experienced one of their coldest days of record. At noon on
that bitterly cold Wednesday the mercury stood at four degrees below at
Boston, 15 degrees below at Norfolk CT, and 17 degrees below at Hanover NH.
The temperature at Boston was 12 degrees below zero by sunset. Gale force
winds accompanied the severe cold, and that night a great New York City
fire destroyed much of the financial district. (David Ludlum)
...1869...
A bill was introduced in the House of Representatives, 41st Congress, 
calling for the taking [of] meteorological observations at the military 
stations in the interior of the continent, and for giving notice on the 
northern lakes and Atlantic seaboard of the approach and force of storms. 
This would be signed in to law February 9, 1870, by President Grant, 
establishing what would come to be called the National Weather Service. You 
can see the actual bill on-line at: 
 here.
...1917...
An ice jam closed the Ohio River between Warsaw KY and Rising Sun IN. The
thirty foot high ice jam held for 58 days, and backed up the river a
distance of 100 miles. (David Ludlum)
...1987...
A Pacific storm battered the coast of California with rain and high winds,
and dumped heavy snow on the mountains of California. Winds along the coast
gusted to 70 mph at Point Arguello, and winds in the Tehachapi Mountains of
southern California gusted to 100 mph at Wheeler Ridge. Snowfall totals
ranged up to 24 inches at Mammoth Mountain. Snow fell for two minutes at
Malibu Beach, and Disneyland was closed due to the weather for only the
second time in twenty-four years. A winter storm which began in the
Southern Rockies four days earlier finished its course producing snow and
high winds in New England. Snowfall totals ranged up to 19 inches at
Blanchard ME. (The National Weather Summary) (Storm Data)
