A Strong Front Will Move Through The Area Friday

A strong frontal system will reach the area on Friday with heavy snow expected in the mountains. One to two feet of new snow is possible by Saturday morning. A winter storm watch is currently in effect for this.

Locally windy conditions are also possible over the lowlands as the front moves through. Most areas will become breezy Friday as the front moves ashore and some areas will become windy. Southerly winds of 20 to 35 mph with gusts to 40 to 50 mph are possible. The strongest winds will likely be near the coast and over the north interior. Winds will turn more westerly and gradually taper Friday night as the front moves inland.

The University of Washington weather model seems to show that most of the wind activity will occur from about 6 AM through Noon on Friday: http://www.atmos.washington.edu/~ovens/loops/wxloop.cgi?mm5d2_slp+///1

Lastly...large swells are expected to impact the coast late Friday night and Saturday. Waves are predicted to reach 22 or 23 feet on Saturday before subsiding. At minimum, dangerous surf conditions can be anticipated on Saturday. The tides will also need to be monitored for the possibility of minor coastal flooding, especially for those low-lying coastal communities that are typically impacted by large ocean swells.
