NWS Heat Index
Heat Index code based off NWS's Heat Index Calculator tool: NWS (National Weather Service). Meteorological Conversions and Calculations: Heat Index Calculator. 2014. Available: https://www.wpc.ncep.noaa.gov/html/heatindex.shtml
Heat index values are not valid for extreme temperature and relative humidity conditions beyond the range of data considered by Steadman (see References). Works with arrays of any dimension and NaN values. If your "no data" values are not set to NaN, convert beforehand or the code won't work.
