15 °F
15 °F feels pretty cold after days of in the 40's but I think that a Snowbird in Florida might think it's nippy, eh? Roger

Fahrenheit (symbol °F) is a temperature scale based on one proposed in 1724 by the physicist Daniel Gabriel Fahrenheit (1686–1736), after whom the scale is named.[1] On Fahrenheit's original scale the lower defining point was the lowest temperature which he could reproducibly obtain using brine (defining zero degrees), while the highest was the best estimate of the average human body temperature (defining 100 degrees), and is thus a type of "centigrade" (100 point gradient) scale. There exist several stories on the exact original definition of his scale, however, and some of the specifics have been lost and exaggerated with time. The scale is nowadays defined by two fixed points: the temperature at which water freezes into ice is defined as 32 degrees, and the boiling point of water is defined to be 212 degrees, a 180 degree separation, as defined at sea level and standard atmospheric pressure.
