When I use Ver.10.10s either the latest regular or latest beta version, I get a crazy high heat index on WDL. See http://www.shermanctweather.com/live.html
I don’t have this proble when I use Ver.10.10r
it wil reset at your next daily reset time
or
reset the number in the wdisplay.ini file (search for humidex), when wd is not running
