Mark Eubank joined the KSL-TV channel 5 Television news team in 1990 as their chief meteorologist. Prior to KSL, he was employed as a meteorologist for KUTV channel 2 in Utah, a position he had held since 1967. Eubank began his meteorology career at age 24 in Redding, California, at KRCR-TV. He attended UCLA and graduated from the University of Utah in 1972 with a Bachelor of Science in Meteorology. Eubank also owned and operated a weather consulting firm, WeatherBank, Inc. for 20 years.
Eubank was famous for wearing a white sports coat throughout a broadcast preceding or during a snow fall.
Indian weather lore such as a Thunder Moon and a Sun dog was often used in his broadcasts.
He was known for his extreme enthusiasm for weather that would usually result in a variety of odd sound effects including: Bing, bowg, boink, boing, boiiiiing, bowk, hah, haaah!, (tearing sound), (squashed sound), ohhhh, goooomph, ziiiing, zoooom, (sound of car stopping suddenly), phhhht, eeerrrrrrumble-rumble-rumble, (slurping sound), sheeewhhhh, oh-oh, vooomph, voom, wonk, vooop, whhktw, waawaa, waaaa, waaam, and zeeek.
“Never trust a split jet stream” was an often repeated phrase during his weather reports.
Eubank also quoted John Ruskin regularly, saying “There is no such thing as bad weather, only different kinds of good weather.”
Eubank was the chief meteorologist of the 2002 Winter Olympics.
On November 29, 2006, Eubank signed off the air for the final time. He passed his job and white coat to his son Kevin Eubank.
