Davis Derived Values:

Windchill = 35.74 + 0.6215T – 35.75 * (V^0.16 ) + 0.4275T * (V^0.16 )

Where: V is the wind speed in mph and T is the outside air temperature in °F. Wind speeds above 55 mph are set to 55 mph. For wind speeds below 5 mph or temperatures above 91.4°F the wind chill is set equal to the air temperature.

Dewpoint = v = RH*0.01*6.112 * exp [(17.62*T)/(T + 243.12)]

Where: T is the air temperature in C and RH is the relative humidity
