The Pacific Northwest “local” has spent his adult life and nearly all his childhood within a 2-hour drive of Portland. He spent his school years in Mt. Angel, Oregon, and Chehalis, Washington. He is a proud “weather geek” who turned in late homework because he spent too much time staring out the window.

When he was 24, Nelsen looked more like an adult and was employed by KOIN. He started his tenure there as a weekend meteorologist and was later promoted to weekday evening meteorologist before moving to FOX 12 in 2000. So far, he has spent more than 28 years on Portland TV!
