List of snow events in Florida

<onlyinclude>




The following is a list of known snow events in Florida. Snow rarely occurs in the U.S. state of Florida, as freezing temperatures in the state are generally caused by the cold and dry winds of anticyclones.</onlyinclude> Frost is more common than snow, requiring temperatures at or less than 45 Â°F (7 Â°C), a cloudless sky, and a relative humidity of 65% or more.[1] Generally, for snow to occur, the polar jet stream must move southward through Texas and into the Gulf of Mexico, with a stalled cold front across the southern portion of the state curving northeastward to combine freezing air into the frontal clouds.[2] Most of the state is in a rare portion of the continental United States which receives a mean maximum monthly snowfall amount of zero, the only other such areas being southern Texas and California.[3] Much of the information prior to 1900 is from a weather climatology provided by the Jacksonville National Weather Service. Information for other locations is sparse.[1] <onlyinclude>

Events

Pre-1900

  • 1774 – A snow storm extends across much of the state. The affected residents speak of it as an "extraordinary white rain."[1]
  • 1797 – Land surveyor Andrew Ellicott reports 8 inch (203 mm) snow drifts near the source of the St. Marys River in Baker County.[4]
  • January 11 1800 – Over 5 inches (127 mm) of snow are on the ground along the St. Marys River to the north of Jacksonville, the highest recorded snowfall total in Florida history.[2]
  • January 13 1852 – Several hours of snow accumulates to a total of a half of an inch (13 mm) in Jacksonville.[1]
  • February 28 1855 – Light snow flurries are reported in Jacksonville.[1]
  • January 29 1868 – Light sleet falls throughout the night in northeastern Florida.[1]
  • February 28 1869 – During the morning hours some snow flurries are reported in Jacksonville.[1]
  • January 10 1873 – At 7:25 am, a few snowflakes fall near Jacksonville.[1]</onlyinclude>
  • February 4 & 5, 1875 – Light sleet occurs between midnight and sunrise on both dates.[1]
  • January 4 1879 – For an hour and a half, sleet falls in Jacksonville before turning to rain. The rainfall covers grounds and trees with ice early on January 5, breaking the limbs to many orange trees.[1]
  • January 5 1887 – An inch (25 mm) of snow falls at Pensacola.[5]
  • January 14 1892 – 0.4 inches (10 mm) of snow is reported at Pensacola.[5]
  • February 14 1892 – Pensacola reports 3 inches (76 mm) of snow.[6]
  • December 27 1892 – Light snow falls in various intervals in the northeastern portion of the state.[1]
  • January 18 1893 – Falling sleet turns to snow before later changing to rain in Jacksonville.[1]
  • February 14 1895 – Two short durations of light snow are reported in Jacksonville.[1]
  • February 12 & 13, 1899 – Rain changes to sleet and later turns to snow during the Great Blizzard of 1899, with the snow falling for about 8 hours. With temperatures of about 10 Â°F (−12 Â°C), the snow accumulates to 2 inches (50 mm) near Jacksonville[1] and 4 inches (101 mm) at Lake Butler.[6] In some locations, the snow remains on the ground for several days.[1]

  • January 24, 2003 – A plume of arctic air produces widespread record low temperatures and light snow flurries along the eastern coastline. The snow is described as ocean effect snow, identical to lake-effect snow in that it occurs due to very cold air passing over relatively warm water temperatures. The snow reaches as far south as Fort Pierce. No accumulation is reported due to rising temperatures throughout the day.[14]
  • December 25 2004 – Locations along the Florida Panhandle receive a dusting of snow.[15]
  • November 21 2006 – An eastward moving weather system produces a very light dusting and snowflakes in central Florida. It is the first snow in November in the state since 1912.[15]
  • February 3 2007 – Very light snow flurries were reported in the panhandle, lasting less than an hour.[16]
  • April 8 2007 – Portions of the western Florida Panhandle received brief durations of sleet.[17]
