The English word "frost" has 2 base meanings that are related to each other but nevertheless sufficiently different: temperature of air below the freezing point of water (ca 273 K) deposit of ice on cold surfaces; The WMO avoids the word "frost" alone [1] and uses

Frost forms when the air contains more water vapor than it can normally hold at a specific temperature. The process is similar to the formation of dew, except it occurs below the freezing point of water typically without crossing through a liquid state. Air always contains a certain amount of water vapor, depending on temperature.
Temperatures will plunge as much as 50 degrees below February averages, with more than 270 temperature records across at least 27 states. Snow headed for flooded areas in Kentucky and West Virginia
Cold hardening is a process in which a plant undergoes physiological changes to avoid, or mitigate cellular injuries caused by sub-zero temperatures. [1] Non-acclimatized individuals can survive −5 °C, while an acclimatized individual in the same species can survive −30 °C.
