Many of you have noticed some wet snow mixed with the rain--even down to sea level. However, the heaviest accumulations occurred where the models suggested: southeast of the Olympic Mountains from Shelton to Silverdale to Quilcene. The reason: temperatures are marginal for snow and only places with heavy precipitation rates...
Lowland Snow?, Thank You, and The Seattle Times Does it Again
| comments
We are now thoroughly stuck in a La Nina pattern, cold and occasionally wet. The mountains are going to get several more feet this week...pretty much guaranteed...but there is also a possibility of some lowland areas....particularly southeast of the Olympics picking up some of the white stuff. A front is approaching the coast right now...

Heavy Rain, Avalanches, and Reduced Threat of Lowland Snow
| comments
While central and western Puget Sound experienced a nearly rain-free day, very heavy rain has struck the western slopes of the Cascades. Take a look at the current upper level pattern (see below)--one with a broad ridge over the eastern Pacific and you might think that nothing much is happening, but such a ridge brings warmer temperatures...
Chance of Lowland Snow Next Weekend?
| comments
I have gotten about a dozen emails the last few days asking about the potential for snow next weekend. I am going to break my normal "120 hr rule" (don't talk about forecasts for more than 5 days out because uncertainty is so large). Yes, the forecast patterns from a number of major modeling systems have produced configurations in the neighborhood...
Big Winds in the Morning (updated)

A strong low pressure center is going to move across northern Washington tomorrow (Sat) morning and the winds will be very strong...there will certainly be some power outages. In the infrared satellite this evening you can clearly see the swirl of clouds with this low: Here is the surface chart for 10 AM tomorrow--nice low center right in...
