Answer: After a snowstorm left a foot of snow over the
city on February 8, 1899, a record cold wave struck. On February 11, the
temperature dipped to -15°F in the District. It was followed by a second great
storm called "The Great Valentines Day Blizzard" which dumped another 20.5
inches of snow. That year DC saw a record 54 inches of snow.
