Mass: 'Perfect Viewing Conditions' For Northern Lights This Weekend

We may get a rare treat this weekend. There’s a real chance we might catch the Northern Light in western Washington, says KPLU weather expert Cliff Mass.

“Perfect viewing conditions,” Mass said. “The skies are not only clear but they’re dry. The viewing is good; the big question is whether we will actually see them.”

A solar flare started Wednesday, says Mass, and some of the particles have already arrived.

Our best chances are on Friday and Saturday nights. Find a spot away from the city lights with a good northward view, says the National Weather Service. 


The weekly KPLU feature "Weather with Cliff Mass" airs every Friday at 9 a.m. immediately following BirdNote, and twice on Friday afternoons during All Things Considered. The feature is hosted by KPLU Environment Reporter Bellamy Pailthorp. Cliff Mass is a University of Washington Professor of Atmospheric Sciences, a renowned Seattle weather prognosticator, and a popular weather blogger. You can also subscribe to a podcast of “Weather with Cliff Mass” shows.
