Winter Weather Returns this Weekend

Melissa Frey’s Forecast Discussion

High pressure is in full force over the Pacific Northwest.  The dry, sunny, warm afternoon yesterday turned into a dry, clear, cold night! Temperatures dropped to 28° by 6 a.m.  We won’t stay cold all day though, in fact we should get all the way up to about 55°.

This high pressure area is going to slide east today, and behind it is a very cold storm that will drop down from the northern Gulf of Alaska.

The front will first bring rain to the Coast mid afternoon, then to the Valley between 5 and 7 p.m.  That precipitation will then make it up into the Cascades first as rain, then as snow. A very cold air mass will move in behind the front, dropping the freezing level from 5,500 feet to 2,500 feet by Saturday morning and 1,500 feet Saturday afternoon.  This storm will also bring in strong winds, especially for the Cacades and Central Oregon.  Gusts could get as high as 60 mph.

Here’s a break down of snow totals expected by elevation for Saturday:

Passes: 7­-15″

Foothills near 2,000′: 4­-8″

Below 1,500′: Rain

The heaviest precipitation will be overnight Friday, but as the center
of the low pressure area moves through, showers will continue Saturday
and Sunday.

For elevations above 1,000 feet, this means light sticking snow
is possible Saturday night through Sunday night and the valley floor could see periods of falling snow Sunday morning and snow/rain mix during isolated showers Sunday.  For a list of elevations in western Oregon click here.

Monday we’ll dry out in between storms, but then it’s going to pick right back up Tuesday.  Freezing levels will stay between 1,000 and 3,000 feet Tuesday through Thursday.  The snow will continue to pile up in the Cascades and Coast Range, with rain showers in the valley and along the coast.

Stay tuned this weekend for any updates.  If you see snow in your area let us know via Facebook, Twitter, or e-mail.

Have a great rest of your Friday!
