As advertised and fairly well predicted by the models, yesterday brought lots of rain, particularly in the mountains, and some notable winds. Looking at the 24 rainfall totals ending 10 PM Saturday (image), you will see some great contrasts. A few hundredths in southeast Washington to 4-5 inches in some of the terrain.
A closer view over western Washington reveals only a few hundredths of an inch in Sequim while more than 5 inches fell a few dozen miles away over the Olympics. 2-5 inches over the western slopes of the Cascades.
There were quite a few power outages yesterday (10-20 thousand out at the peak), mainly due to the strong winds associated with a powerful front that came through around 4-5 PM. The radar was impressive...a classic narrow cold frontal rain band (see line of red in the radar image below...red indicates downpour intensity).
So what about today? Showers are over western Washington and Oregon now (see radar at 9:45 AM) except for some rain shadowing in the lee of the Olympics
Off of Vancouver Island there will probably be winds sustained at 40-55 mph with hurricane-force gusts. The UW WRF surface wind forecast at 5 PM (see below) shows sustained winds of 35-45 mph on our coast and a bit weaker winds over the Strait and NW Washington.
As the low moves past us to the north, winds will increase over Puget Sound and NW Washington. For example, at 11 PM tonight (Sunday) there will be a large north-south pressure difference over western Washington, aided by troughing (lowering of pressure) to the lee of the Olympics. A blustery night, particularly over NW Washington. There will be more power outages..so be prepared.
