WeatherWatcher: Winter Weather Advisory - Marginal snow chance

Saturday, March 4, 2017

The National Weather Service in Seattle has once again issued a winter weather advisory. The advisory is in effect from 10pm Saturday night until 10am Sunday morning. Accumulations of 0-2 inches are possible from about 200 feet in elevation and up. 

Forecast: This is a repeat basically of last weekend - Tuesday. We have a showery cold weather pattern that's taken hold over the area that is expected to bring in rain or mixed rain and snow showers during the daytimes with snow or rain and snow mixed showers over night into Tuesday morning. Occasional dustings or 1-2 inches of wet snow accumulation are possible but won't stick around too long after the shower passes.

We are at the southern edge of the cold air, where places further north such as Lynnwood, or Everett are expected to see up to 5 inches possible by Sunday night. Keep in mind a slight change in the weather pattern and track could bring that slightly colder air south of the King / Snohomish county line.

Bottom line: Another marginal snow weather pattern, where some higher hills could get some snow. It is once again a hit or miss shower type pattern. Main impact will be local driving conditions becoming hazardous at times between now and Tuesday afternoon. I'm giving a chance of accumulation snow precipitation of about 60% for the Shoreline and Lake Forest Park area, slightly greater chances of course if you are on one of the higher hills.
