Historical Weather And Climate Facts For Today JANUARY 23RD HISTORICAL WEATHER FACTS ...1780... The coldest day of the coldest month of record in the northeastern U.S. A British Army thermometer in New York City registered a reading of 16 degrees below zero. During that infamous hard winter the harbor was frozen solid for five weeks, and the port was cut off from sea supply. (David Ludlum) ...1971... The temperature at Prospect Creek AK plunged to 80 degrees below zero, the coldest reading of record for the United States. (David Ludlum) ...1987... Strong winds ushered bitterly cold air into the north central U.S., and produced snow squalls in the Great Lakes Region. Snowfall totals in northwest Lower Michigan ranged up to 17 inches in Leelanau County. Wind chill temperatures reached 70 degrees below zero at Sault Ste Marie MI and Hibbing MN. (National Weather Summary) (Storm Data) ...1988... Northeastern Colorado experienced its most severe windstorm in years. A wind gust to 92 mph was recorded at Boulder CO before the anenometer blew away, and in the mountains, a wind gust to 120 mph was reported at Mines Peak. The high winds blew down a partially constructed viaduct east of Boulder, as nine unanchored concrete girders, each weighing forty-five tons, were blown off their supports. (National Weather Summary) (Storm Data) ...1989... Low pressure brought heavy snow to Wyoming, with 18 inches reported at the Shoshone National Forest, and 17 inches in the Yellowstone Park area. Gunnison CO, with a low of 19 degrees below zero, was the cold spot in the nation for the twelfth day in a row. (National Weather Summary) (Storm Data) ...1990...
