Shoreline Weather
  • About Warnings and Advisories
  • Wind, or not?
  • Winter Weather Advisory issued

About Warnings and Advisories: When I write about the National Weather service issing warnings or advisories I am relaying information based on what they are expecting under the advisory or warning. In the case of wind speeds and snow accumulations I am going off what their warning/advisory is expecting.

Wind, or not? Yesterday evening the National Weather Service in Seattle had issued a High Wind advisory for the area. We never saw the winds that they were forecasting of 20-35mph with gusts to 55mph. Why not? Well because the "eye" of the storm, or center of the low pressure actually passed quite a bit further south than they (National Weather Service) expected. The center of the storm passed almost directly above us. As a result areas north of Everett, South of Downtown Seattle, and everywhere else all around us received strong winds, gusting to 59mph at Seatac Airport.  

The strongest gust we received here in north Shoreline at the Home Education Exchange center (Previously known as North City Elementary) was 31mph. Winds peaked at around 2-4am and eased after that quickly as the low pressure moved east of the Cascade Mountains.

Snow: Tonight, the National Weather Service of Seattle has issued a Winter Weather Advisory for North King County and all of Snohomish County lowlands for snow, 1-3 inches possible. Shoreline and Lake Forest Park are part of North King County. It is expected that a convergence zone band will develop late this evening and persist tomorrow morning. The Advisory is in effect from 10pm tonight until 12pm Tuesday.  This is a hit or miss situation so we may get dumped on with snow, or we may not see anything at all. 

At any rate we will see very cold temperatures tonight, we are expected to drop below freezing so even if there isn't snow fall, the water currently on the roadways can freeze up forming black ice, so be careful tomorrow morning if you are heading out on the morning commute regardless.
