Local and Regional Events:

December 20, 1991:

Light freezing drizzle and freezing rain developed over northern South Dakota from Timber Lake to Webster. Numerous car accidents were attributed to slippery conditions. The Aberdeen Police Department reported 24 accidents in Aberdeen, but only one resulted in an injury. Numerous businesses closed and schools were canceled.

December 20, 2008:

Arctic air combined with blustery northwest winds brought extreme wind chills to the central and northeast South Dakota and west-central Minnesota from the late afternoon of the 20th until the afternoon of the 21st. Wind chills of 35 below to 45 below zero were common across the area.

U.S.A and Global Events for December 20th:

1836: A famous "sudden freeze" occurred in central Illinois. A cold front with 70 mph winds swept through around Noon, dropping the temperature from 40 degrees to near zero in a matter of minutes. Many settlers froze to death. Folklore told of chickens frozen in their tracks and men frozen to saddles. Ice in streams reportedly froze to six inches in a few hours.

1929: An exceptional storm produced snow from the Middle Rio Grande Valley of Texas to southern Arkansas on December 20 - 21st, 1929. The storm produced 26 inches of snow near Hillsboro, Texas, and 24 inches in 24 hours in Clifton. Click HERE for more information from the NWS Office in Dallas / Fort Worth.

1977: A "Once in a Lifetime" wind and dust storm struck the south end of the San Joaquin Valley in California. Winds reached 88 mph at Arvin before the anemometer broke, and gusts were estimated at 192 mph at Arvin by a U.S. Geological Survey. Meadows Field in Bakersfield recorded sustained 46 mph winds with a gust of 63 mph. The strong winds generated a wall of dust resembling a tidal wave that was 5,000 feet high over Arvin. Blowing sand stripped painted surfaces to bare metal and trapped people in vehicles for several hours. 70% of homes received structural damage in Arvin, Edison, and East Bakersfield. 120,000 Kern County customers lost power. Agriculture was impacted as 25 million tons of soil was loosened from grazing lands. Five people died, and damages totaled $34 million.

These strong winds also spread a large fire through the Honda Canyon on Vandenberg Air Force Base in southern California. This fire, which started from a power pole on Tranquillon Ridge being blown over, claimed the lives of Base Commander Colonel Joseph Turner, Fire Chief Billy Bell, and Assistant Fire Chief Eugene Cooper. Additionally, severe burns were experienced by Heavy Equipment Operator Clarence McCauley.  He later died due to complications from the burns. Click HERE for video of the fire.

1984: Lili, a rare December hurricane, was officially declared a tropical system in the central Atlantic as a distinct eye type feature was apparent on satellite imagery. The hurricane peaked at sustained 80 mph winds and a pressure of 980 millibars or 28.94 inches of mercury, a very respectable Category 1 Hurricane in December.

The image shows Hurricane Lili on December 22, 1984, with winds of 80 mph.

2006: Severe Cyclone Bondo, the equivalent of a Category 4, approaches the Madagascar coast with sustained winds of 138 mph. Click HERE for more information from NASA’s Earth Observatory.
