# I use a Python script to pull current weather conditions from the NOAA web service API. The NOAA web
# service does not return a windchill value for all locations, but given temperature, relative humidity,
# and wind speed you can calculate a “feels like” temperature as follows.

# This code assumes units of Fahrenheit, MPH, and Relative Humidity by percentage.  In this example, a
# temperature of 35F, wind speed of 10mph, and relative humidity of 72% yields a "feels like" value of 27.4F
