Being in the south, Alabama, 20 miles from the Gulf, as the article mentions, it's very humid in the summer. As the saying goes, you can cut the air with a knife. Knowing the humidity makes the air very uncomfortable. Curiosity, I bought gages with both the temp and relative humidity readings. Having three of them, they all were within 1-2 degrees, so were fairly accurate it seemed. I have charts that notes the Heat Index for various readings as OFA also has. But many times the Heat Index is off the chart(s). Searching the NET found a web site that inserting the temp and
humidity it instantly gives the Heat Index. From NOAA https://www.wpc.ncep.noaa.gov/html/heatindex.shtml It's a fun site. One table is for Dew Point and another is for Relative Humidity.
To make matters more confusing, I found a site showing the formula to determine the Heat Index, quite complicated. From the National Weather Service: https://www.weather.gov/ama/heatindex
A sampling of my record keeping My Codes:
FS = Full Sun, gage placement
PS = Partial Sun
OC = Over Cast
HI = Heat Index Temp (from chart) degrees
HM = Humidity
HD = Heat of Day @ 2:00 pm
OT = Outside Temp
IT = Inside Temp
7/07 OT FS HD 115 F HM 90% HI = off the chart HI = 151 degs (per the input table)
Ready for winter. The south may be hot, but in Vermont 2 or 3 years ago it was 104 in the shade.
