New Year's Forecast

| comments

Today is a typical post-frontal day, with unstable air producing showers and good orographic precipitation in the mountains. There is also a Puget Sound convergence zone enhancing precipitation north of Seattle and rain shadowing immediately east of the Olympics (see radar to see the precip and the surface chart to see the winds wrapping around the Olympics and converging over Puget Sound).
As I noted in my previous blog, it does not look like we will get a big fact, not much of windstorm at all. There will be a complex dual low system, with the first coming in tomorrow morning over or just to the north of us. If it does go north, we might get breezy, but no serious winds. The system is also weaker than the earlier model simulations. This system will bring steady rain to us tomorrow and lots of snow in the mountains. Take a look at the computer snow forecasts...we are talking FEET over the next 48 hrs (these images show 24-h snowfall ending tomorrow and Friday at 4 AM).

Now I don't want to get the TV stations too excited (although I do enjoy Jim Foreman's antics on KING TV)...but some of the models are suggesting the potential for snow after the second system moves through early Friday morning. 2-6 inches from central Puget Sound southward. This snow will depend critically on the trajectory and precipitation with the second system. Anyway, time to go to your local hardware store for some salt....just in case. And if the snow occurs it will be an interesting test to see of the City of Seattle and other municipalities has learned something from the past experiences.

MAJOR ANNOUCEMENT: The City of Seattle has decided to use salt for major storms!

Thanks to all of you that have expressed your opinions about this...I know that several City of Seattle staff members have been following this blog... Now they have to deal with lack of plows, the crazy pack it down rather than remove policy, and to get Metro to deal with snow events in a rational way. And hopefully they will fix their web site to deal with snow events...right now it is a disaster.
