Weather with Cliff Mass

Lifting Fog, Persistant Ridge And Mysterious Cloud Patterns Over Seattle
If you got caught in the fog on Thursday, you were not alone. KPLU weather expert Cliff Mass says he, too, got a bit lost in the muck on his way to the airport.
Good News: No Burn Ban
The fog that lingered near Tacoma and Lynnwood will melt away soon, says Mass, who teaches atmospheric sciences at the University of Washington.
And there's a 50 percent chance of rain in the forecast, which is probably why there is no burn ban at the moment.
"There's a weak front approaching," said Mass, adding the front will cause the fog to dissipate.
Bad News: Not Much Snow For Skiers
There will be rain, but the warm air above us will keep the passes from getting much snow.
"I hate to say it, but this ridge is coming back again," said Mass.
The persistent ridge has been extraordinarily persistent and holding down a pattern that doesn't bode well for skiers and snowboarders.
What Are Those Clouds In The Sky?
Mass says he received multiple reports and pictures of a wavy cloud pattern in the sky over north Seattle. This pattern is called Kelvin Helmhoz, after two men.
"It looked like the waves were breaking in two directions," Mass said.
Mass says it's something that occurs when two currents from opposite directions collide in the air.
"This is a great mystery that I am going to try to figure out," said Mass, adding he is investigating the phenomenon and will write about it in an upcoming blog post.
