PORTLAND – Freezing fog and black ice are creating awful conditions for the Wednesday morning commute throughout the Portland area.
Evergreen School District has canceled classes because of the driving danger.
"We're at or below freezing just about everywhere, which means freezing fog and slick roads for basically the entire area," said KGW meteorologist Nick Allard.
Westbound lanes of I-84 at I-205 were closed for a time due to an accident. Two accidents were also reported on I-5 southbound at Ridgefield.
Temperatures briefly climbed above freezing Tuesday afternoon, the first time it's been that warm since December 4.
As cold conditions began to relent Tuesday afternoon, many schools remained closed or opened late. However, Oregon State University which shuttered over the weekend, resumed classes Tuesday, despite significant snow.
Several flights at Portland International Airport were delayed or canceled Tuesday due to poor weather conditions at their destination cities. See the list
The recent cold weather snap may be connected to one death in Longview Wash., police said Monday. A woman found outside her retirement home Thursday morning died of hypothermia, investigators said.

The coldest night of this cold snap came overnight Saturday with temperatures at Portland International Airport dipping down to 13 degrees. Temperatures created spectacular scuptured ice at Columbia Gorge waterfalls throughout the weekend.
In Salem, temperatures were as low as 8 degrees, but that was nothing compared with Eugene, which saw -10 degrees, coming within 2 degrees of a record low.
The arctic air blast followed a wild weather pattern Friday that brought a dusting of snow to the Metro area, anywhere from 1 to 2 inches in Southwest Washington, and the Oregon Coast, and all the way up to 9 inches in Albany and Corvallis.
