Historical Weather And Climate Facts For Today

FEBRUARY 12TH
HISTORIC WEATHER EVENTS
...1899...
Texas and the eastern plains experienced their coldest morning of modern
record. The mercury dipped to 8 degrees below zero at Fort Worth TX, and to
22 degrees below zero at Kansas City MO. The temperature at Camp Clarke NE
plunged to 47 degrees below zero to establish a record for the state. In
the eastern U.S., Washington D.C. hit 15 degrees below zero, while
Charleston SC received a record four inches of snow. (David Ludlum)
...1958...
Snow blanketed northern Florida, with Tallahassee reporting a record 2.8
inches. A ship in the Gulf of Mexico, 25 miles south of Fort Morgan AL,
reported zero visibility in heavy snow on the afternoon of the 12th.
(12th-13th) (The Weather Channel)
...1960...
A snowstorm in the Deep South produced more than a foot of snow in
Louisiana, Mississippi and Alabama. (David Ludlum)
...1981...
Eastern Kentucky had record subzero temperatures in 1981. The mercury bottomed 
out at 7 degrees below zero at the London Corbin airport...while the Jackson 
weather office dropped to minus 4 degrees. 
...1985...
Heavy snow paralyzed Eastern Kentucky back in 1985. The snowstorm dumped between 
10 inches and 2 feet of snow within an 18 hour period...virtually bringing 
Eastern Kentucky to a standstill and isolating hundreds of Kentuckians... 
especially those within the mountain homes of extreme Eastern Kentucky. Roads 
were impassable with drifts up to 20 feet high as well as trees and power lines 
blocking roads. National Guard helicopters were used to locate stranded 
motorists...evacuate residents without electrical power and scout road 
conditions. Snow records that still stand today include...11 inches at the 
London-Corbin airport and one foot of snowfall at the Jackson weather office.
(NWS Jackson, KY)
...1987...
A storm in the eastern U.S. produced high winds from North Carolina to
Maine. A storm in the western U.S. produced up to thirty inches of snow in
the Sierra Nevada Range of California. (The National Weather Summary)
(Storm Data)
...1988...
A classic "nor'easter" formed off the Carolina coast and intensified as it
moved up the Atlantic coast bringing heavy snow to the northeastern U.S.
Totals ranged up to 26 inches at Camden NY and Chester MA. Arctic cold
gripped the north central U.S. Duluth MN was the cold spot in the nation
with a low of 32 degrees below zero. (The National Weather Summary) (Storm

...1989...
Unseasonably mild weather prevailed across Alaska. Morning lows of 29
degrees at Anchorage and 31 degrees at Fairbanks were actually warmer than
those in northern Florida. (The National Weather Summary)
...1990...
Strong southerly winds ahead of an arctic cold front pushed temperatures
into the 70s as far north as Iowa and Nebraska. Twenty-one cities in the
central U.S., seven in Iowa, reported record high temperatures for the
date. Lincoln NE reported a record high of 73 degrees, and the afternoon
high of 59 degrees at Minneapolis MN smashed their previous record for the
date by twelve degrees. Springfield IL reported a record forty-eight
consecutive days with above normal temperatures. (The National Weather
