The visible satellite picture today show two things...the clouds on the western side of the Cascades and the approaching weather system offshore. Eastern Washington and Oregon are nearly clear and sunny. We have now switched to the period when eastern Washington no longer clouds in...so very frequently they are clear, when the west side is in clouds. A good time to visit your favorite winery and dry-land hike.

The approaching system is stronger than most this time of the year and the low center will cross northern Vancouver Island (see image for 8 AM tomorrow). It will get breezy later tomorrow am as the low passes north of us, but the big issue will be rain.

The two images that follow show you the predicted 24-h precipitation ending 5 PM tomorrow and Monday. Quite wet tomorrow--with the model going for 2-5 inches on some windward slopes! And a spectacular rainshadow. Head to Sequim tomorrow...somewhere around there may be completely dry...maybe even with some sun breaks. The second day precip is still signficant..but those are mainly showers...with a strong Puget Sound convergence zone (see the next figure for 11 PM on Sunday). Behind the system, temperatures and the snow level will drop...and expect snow..lots of it above 1500 ft (check on the 24h snow ending Monday at 5 AM)
