Icy Mix, Snow Headed for Seattle and Portland

A wintry mix could dump several inches of snow and ice on both Seattle, Washington and Portland, Oregon on Thursday and into Friday, potentially making road conditions very dangerous in both locations.

Cold air left behind a strong front earlier in the week coupled with a big Pacific area of low pressure will combine to produce snow in Seattle and Portland for the first time in a long time.

The snow is expected to start in Seattle around midday on Thursday, accumulating 1-4″ during the day and through the early evening hours before switching to plain rain late Thursday night and into early Friday morning, once warm, Pacific air moves in.

In Portland, the wintry weather starts earlier in the form of a heavy, wet snowfall on Thursday morning before changing over to freezing rain and sleet during the afternoon and early evening. The drive home on Thursday in and around Portland is expected to be particularly treacherous, with snow and ice packed in on area roadways. The wintry mix then flips over to all rain before daybreak on Friday.

A Winter Weather Advisory is in place for Seattle, and a Winter Storm Warning goes into effect at 8am Thursday morning in Portland.

It’s been a while since both places have seen significant wintry precipitation of any kind. The last time Seattle saw measurable snowfall was November 29th, 2014, making it an over two-year drought since the Emerald City has seen any measurable snowfall. Portland saw 1.3″ of snow on January 3rd, the last measurable snowfall in the city, and the only accumulating snow the Rose City saw all of last winter.
