WeatherWatcher: Winter Weather Advisory, Winter Storm Watch

Winter Weather Advisory has been issued by the National Weather Service in Seattle for the region, including Shoreline and Lake Forest Park. The Winter Weather advisory is in effect from 4am Monday morning until noon Monday. Snow showers are expected to pick up Monday morning a little after 4am with a possible 1-2 inches of accumulation. Snow is expected to mix into rain in the afternoon for a short time.

Winter Storm Watch has been issued for Monday afternoon through late Monday night. A second surge of cold air is expected to push into the region and with it a convergence zone over north King and south Snohomish County. This puts Shoreline and Lake Forest Park almost dead center of the storm. In general another 1-3 inches is possible over the whole region, with locally heavy amounts in the Shoreline area to be closer to 4-7 inches total by the time everything is done Monday night.

There is still great uncertainty with these two events, and it's possible the Puget Sound Convergence could miss Shoreline and Lake Forest Park, leaving us with just 1-2 inches of snow.  The closer you are to Puget Sound and Lake Washington will limit accumulations further.

I expect areas such as the Richmond Beach Highlands, Hillwood, Ballinger, Ridgecrest, North City, Highland Terrace, Westminster Triangle and Echo Lake neighborhoods to be hit the hardest of the areas inside Shoreline. The Lake Forest Park Horizon View Park area will also likely see higher accumulations.

Further out, cold and sunny conditions will dominate the area Tuesday - Wednesday evening, when the next Pacific storm begins to move in bringing renewed snow before changing over to rain Thursday afternoon. Rain still appears to be on the forecast for Friday-Sunday. Longer range still is hinting at a new threat of snow beginning of next week.
