Wet Bulb is not a new concept to me. WHY? Because I've been using NOAA for many years. National Oceanic and Atmospheric Administration - NOAA. One of the oldest agencies in the Federal government. I grew up Florida - we HAD to know the weather.

TEMP. - first item that shows. Then WIND, includes direction and velocity. Most important - HUMIDITY - a %. And NOAA even tips you off to what the combo of those 3 measurements mean to your daily life. AND IT'S FREE! You can look up any scant or very large city, town, or airport in the US. One part of includes tne NHC - National Hurricane Center - tons of information - even when they're forming in the eastern Atlantic
