Two advisories were released Friday (Dec. 4th) – by the National Weather Service and King County, warning of “Arctic air” moving in as well as the possibility of “slick driving conditions” this weekend as temps drop down into the low 30s and upper 20s.

Sadly for most school-aged children, no snow is in the forecast (sorry kids…).

First, the National Weather Service’s “Special Weather Statement” released at 4:46pm 12/4:

… Cold weather to continue into next week for western Washington…

A secondary and stronger surge of cold air will filter into western Washington late this weekend. Temperatures will continue to run well below normal into late next week as Arctic high pressure slides south in western Canada allowing modified Arctic air into the area. High temperatures will remain in the 30s through most of next week with low temperatures well below freezing.

Snow showers are possible Saturday night as an upper low passes over the region. No accumulations are expected… except perhaps light accumulations for the northern shores of the Olympic peninsula where an upslope component and moisture picked up over the northern interior waters may produce accumulating snows late Saturday night and Sunday morning. Windy conditions will develop  Saturday evening through the first half of Sunday for the northern interior and Strait of Juan de Fuca as Fraser outflow increases.

And here’s King County’s warning on road conditions (link to the county’s road condition map here):

King County Road Alert Spotlight

The King County Road Services Division is alerting motorists of the possibility of slick driving conditions as temperatures cool and roads remain wet.

A brief rain shower that moved through parts of the county this afternoon may leave just enough moisture on some roadways to cause slick driving conditions tonight.

While many roads in unincorporated King County have been treated with anti-icing materials, motorists should still be on the lookout for icy stretches of roadway, especially in higher elevation areas and on bridges and overpasses.

If you are traveling tonight or early tomorrow morning, use extra caution and be prepared for winter driving.

And one more weather-related blurb to share, this one from noted Meteorologist Cliff Mass’ Blog on Thursday, Dec. 3rd

You have delicate plants…protect them. When the winds die down on Monday morning the temperatures could plummet on the western side into the teens in some locations. Maybe even colder Tuesday am. Good weather for plumbers–could have some frozen and bursting pipes.

And watch the action offshore! As the cold air moves over the relatively warm water there will developing cumulus activity…including showers. There will be lines of convection…should be impressive.

Monday and Tuesday will be cold and sunny. That’s far enough to forecast…but remember…sometimes the most interesting weather happens when a cold spell ends. I won’t even mention that unspeakable four letter word: S**W. Don’t even think about it.
