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.

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
