From the Annals of the Blue Northers –  In 1899, the coldest temperature ever recorded in Texas occurred in Tulia.  Thermometers recorded a temperature of minus 23 degrees Fahrenheit.  The frigid air was part of the “Big Freeze”  (a/k/a the Great Blizzard of 1899) perhaps the most famous blue norther ever to reach the state.  Record lows that still stand today were recorded across much of the eastern U.S. including the only subzero temperature ever recorded in Florida.  In Texas, the blizzard killed thousands of head of livestock and damaged crops.
