Response Format

key - Your secret key
lat - The latitude of the requested location
long - The longitude of the requested location
weather - An array of weather data. Data includes minimum temperature, wind speed, dew point temperature, and relative humidity
validTime - The timestamp for the frost/freeze probability
probFrost - The probability of frost. This is based on temperature and moisture. Hence, you can have below freezing temperatures, but dry conditions, and not have a frost. Likewise, temperatures can be slightly above freezing, but the dew point low enough to allow a frost.
probFreeze - The probability of a freeze. This is based on the surface temperature remaining below freezing for several hours.
