Today we had an active atmospheric river over western Washington and Oregon, producing some impressive one-day totals. Take a look at the total precipitation for the 24-h period ending 8 PM on Wednesday (see image). Some locations (such as near the SE side of the Olympics) have reached over 4 inches, while 2-4 inches was widespread over terrain. Only portions of eastern Washington received less than .05 inches.
The 24-h rainfall amounts from Seattle Rainwatch, based on the Camano Is. radar, shows a huge contrast in western Washington, ranging from 2-3 inches in the southern Sound to roughly half that north of Everett.
The partial solar eclipse
A partial eclipse of the sun will occur tomorrow (Thursday) afternoon starting at 1:36 PM and ending at 4:20 PM here in Seattle. Will it be clear enough for you to see it?
Here is the UW WRF model's cloud forecast for 3 PM. Best place to go for a chance for clear skies? The eastern slopes of the Cascades.
And finally, I and others have been watching the potential storm on Saturday. The solutions have shifted a bit, but right now it looks like we will have a decent blow on Saturday night, but not an historic windstorm.
On Saturday at 11 AM, the pressure forecast shows a strong, but elongated low off the Washington/Oregon coast. Elongated is not good...you want a compact, concentrated storm. But there are large pressure gradients along the northern CA and southern Oregon coasts--40-60 mph gusts are possible
