Weather highlights for the week:

We had a fairly wet day on Thursday the 23rd, receiving over an inch of rain. Otherwise this week was pretty quiet weather wise.

Weather for the coming week:

Watch out for Wednesday night - Friday, forecasters are expecting a cold low pressure system to develop in the Golf of Alaska bringing down arctic cold air into the Puget Sound region which may result in possible snow here in Shoreline. 

This seems to be consistent through multiple forecast centers (including the National Weather Service of Seattle.) I've found in my experience that when multiple agencies are predicting the same general weather pattern that it is much more likely to occur. I'll keep you posted if any winter storm warnings, watches, or advisories pop up.
