Thing are really getting interesting now. See the surface chart above at 2 PM. The low center is MUCH stronger than the model's predicted. Around 999 mb and is now located over the Olympic Peninsula...as a result southwesterly winds are picking up in the south Sound and the northerlies are strengthening to the north. The collided airstreams are causing enhanced vertical motion and precipitation. Look at the radar...a line of very heavy reflectivities...and snow intensities has formed south of Seattle. Strong northerly flow is now striking the northern portion of the Olympic Peninsula and very heavy snow is falling on its northern side (6-10 inches so far in some places!!!!)
The show is not over yet.
Here is a neat time-lapse of snow in Silverdale. Looking west across Hood Canal
