Feb. 5 marks the birthday of one of the first known weather observers, a Bostonian named John Jeffries who was born in 1744. Jeffries first made a name for himself as a military doctor during the Revolutionary War. In 1774, he began recording daily weather observations. Ten years later, he also began taking logging information about the weather from a hot air balloon.

Now his birthday is celebrated as National Weatherperson's Day, a day to honor the meteorologists, climatologists and other weather observers for the work they do to produce forecasts. It's also a day for recognizing the incredible advances that have been made in weather technology since Jeffries' days in the balloon, from computer models to satellites to radar.
