Today is National Weatherperson’s Day in the United States. While not an official federal holiday, it is a day to recognize the work of all individuals involved in the field of meteorology – not just prognosticating groundhogs.

According to the NWS, February 5, 1744 was the birthday of Dr. John Jeffries – one of America’s first weather observers. As a Boston based physician with a deep interest in weather, he kept detailed records of daily weather conditions from 1774 to 1816. He also took the first known upper air observations from a hot air balloon in 1784.

Recognizing the significant contributions Dr. Jeffries made to the science of meteorology, this date was chosen in his honor.
