FERNDALE, Wash. — Forecasters with the National Weather Service Seattle office say there is a possibility of lowland snow beginning the end of the week but also reasons not to bet on it.
In the short-term, forecasters say there is a chance of rain and snow periodically from Wednesday night through Thursday while the chance of precipitation is 30%.
In the long-term, forecasters said this morning snow levels could begin dropping as early as Saturday as a very cold arctic air moves across British Columbia and possibly southward. Highs in the 30s and lows in the 20s could be expected for northern Puget Sound lowlands including the Ferndale area.
But at this time, forecasters say, it is unclear if this arctic front will 1) drop south across western Washington, 2) stay in BC or 3) move east of the Cascades.
In addition, it is unclear how much moisture there would be to fall as snow if this arctic front were to drop south. Typically, these “continental polar/arctic air masses” cannot hold much moisture according to forecasters.
The current forecast is for colder temperatures but also decreasing chance of precipitation as the snow level drops closer to sea level.
