Wow!
On August 13, 2012, Needles, CA experienced a thunderstorm that deposited rain at a temperature of 115 °F (46 °C) starting at 3:56 PM, setting a new record for the hottest rain in world history. The air temperature was 118 °F (48 °C), tying Needles' record high for the date. Since the humidity was only 11%, the rain evaporated so that "only a trace of precipitation was recorded in the rain gauge". Weather records researcher Maximiliano Herrera reported that this was the lowest humidity at which rain has occurred on Earth in recorded history.
I stopped in Needles once back when I was driving a 18-wheeler. It does get hot there.
