...AREAS OF BLACK ICE COULD IMPACT THE FRIDAY EVENING COMMUTE DUE
TO A FLASH FREEZE...

At 11 AM PST Friday, temperatures were rapidly dropping across
southwest Washington and far northwest Oregon, including the
Portland/Vancouver metro, Columbia River Gorge, north Oregon
coast, and north Oregon Coast Range. In fact, many locations
within the aforementioned areas were already below freezing at 11
AM Friday. An arctic cold front dropping from the north, combined
with cold easterly winds developing in the Columbia River Gorge,
will result in rapidly cooling temperatures through Friday
afternoon and evening. By approximately 3 PM PST Friday, 
temperatures should be in the 20s. Given the wet road conditions 
leading up to the flash freeze, areas of black ice are a concern. 
As such, slippery road conditions could impact the Friday evening 
commute, prior to the arrival of a winter storm set to impact 
southwest Washington and northwest Oregon Friday night through 
Saturday night. Sidewalks and other surface may also become icy.
