Surprised SPC isn't noting this in their Day Two discussion, but perhaps because it may be such a localized event, it doesn't warrant mentioning at the moment.
Tomorrow's forecast looks tricky for the Puget Sound Convergence Zone (Seattle, Everett, Tacoma area) as convective temps may not even be realized at all.
It's very cold, as we had scattered snow throughout the Seattle area this morning. Warm front now pushing onshore though.
However, models pick up on a rather strong PSCZ forming later in the PM tomorrow, with rather impressive lapse rates over the entire area. Obviously, widespread small hail / grauple events will be possible. In addition, strong convective storms may develop in a defined triple point area between Vancouver, BC, Canada and Seattle/Tacoma, WA. Shear will be rather impressive as well......... appears to be a classic Pacific cold core setup pushing into western WA. If we can manage a few sun breaks here and there, although that's a tall order, a little surface heating could really get the convergence zone cranking! Models show two CZs possible, so it could be interesting.
Bottom line... would not be surprised at all to see some low-topped SVR warned cells and perhaps even an isolated cold funnel / tornado!
It will be a fun day for all types of weather chasing, from thunderstorms to driving maybe 15 miles and be in blinding thundersnow squalls. Will post report if this does actually evolve.
