Wet Bulb Temperature
The air temperature drops after it rains. In the summertime a thunderstorm can break the oppressive heat of the day. As it precipitates, evaporation occurs and the air temperature drops. The wet bulb temperature is the temperature at which no more evaporation will occur, and thus no further decrease in the temperature. The air will continue to cool until the air can evaporate no more moisture. The temperature, when the cooling continues until the evaporation stops and the air becomes saturated, is the wet bulb temperature.
