Florida's climate is low latitude and subtropical. Temperatures that are cold enough to have snowfall do not happen long. Frost is more likely to happen than snow because it needs a temperature of 32°F or 0°C, less than 2 m or 7 ft above sea level, no clouds in the sky, and a relative humidity of 65% or more. For snow to happen in Florida, a polar jet stream must go south through Texas and the Gulf of Mexico. A cold front has to stop around the south part of Florida and curve northeast to add very cold air into clouds.
