The origin of the 'Alberta clipper'

Dear Tom,
I am a retired forecaster from the old Springfield, Ill., National Weather
Service office. Who originated the term, "Alberta clipper," and when?
Fred Snowden, Springfield, Ill.
Dear Fred,
"Alberta clipper" is a colorful term that appeared in meteorological jargon
in the early 1970s, courtesy of Rheinhart Harms. At that time, Harms was the
Meteorologist-in-Charge of the Milwaukee, Wis., Weather Bureau office, and
he authored a research paper titled, "Snow Forecasting for Southeastern
Wisconsin" in 1970.
Harms noted that a distinctive class of snow-producing low pressure systems
originated in or near Alberta Province, Canada, and moved rapidly southeast
across the Midwest, producing a belt of low water-content snow. He called
those storms "Alberta clippers," and staff members of the Milwaukee weather
office began using the term in the early 1970s.
