Snow 🔜 425 ❄️
Latest weather models signal snow for Lake Stevens — but stay tuned
BREAKING - The National Weather Service issued a Winter Storm Watch covering Lake Stevens and much of the 425, with four to eight inches of snow possible beginning Tuesday afternoon through Wednesday.
This is inline with the latest meteorological products available through the EMCWF “European” forecast and the UW Dept. of Atmospheric Science.
See below for access to the most granular and precise forecast available in the 425.

J425 was in the process of editing and distributing the latest run of weather models showing snow for the 425 as the National Weather Service update hit. (J425 subscribes to a professional society that provides access to localized forecasting through the world leading “European” model.
During periods of interesting weather we leverage this access for our subscribers. That’s why J425 subscribers were informed of the coming snow storm last Friday).
The latest UW models show most of Snohomish County getting hit with between four to eight inches of snow by midday Wednesday.
Further, J425 ran detailed localized forecasts through the European composite — which takes into account our elevation (461’ at the high school) and relative position closer to the Frasier River outflow (the cold air faucet in Bellingham) to provide the most granular forecast possible for a Lake Stevens resident.
In short, it’ll get cold tonight — but not pipe snapping cold — and then precipitation will begin right around the time the USMNT gets done mopping the floor with Iran — call it noon Tuesday.
Models show an above 90% chance of snow by 4 pm tomorrow. When and if it begins to stick will be a byproduct of how cold it gets tonight and how much (if any ) southerly winds we experience tomorrow.
We’ll leave you with these latest charts and forecasts and update everyone again as necessary.
Because subscriber fees are used to access the European weather service, this is a subscriber only post. Thank you for your support.
Edit — The question has been asked why listen to J425 about weather? Short answer: We’re the only ones with access to Euro modeling running specific forecasts for our coverage area. That said, we do have a track record you can judge us against. 👇
