There isn't even a mention of the word 'snow' for the EPSL zone forecast. Not even rain/snow mix. Sometimes those surprise events are the best though. Catch everyone off-guard, even pro mets. Kind of fun. It won’t be great for the people that are out and about if this event exceeds expectations since Seattle metro comes to a halt with 1in of snow.

jakerepp Posted December 20, 2020 Report Share Posted December 20, 2020 I guess the pro Mets know that there is no way of pinpointing what, if anything, will happen in a marginal scenario like this. Maybe they think it’s better to not really make a fuss about it at all then it would be to hype it up the way the snowfall maps are indicating. Certainly a much better chance of a ‘bust’ than a ‘boom’.

Perhaps you guys can add these into your inventory. Fascinating fun fact on this little guy! Each September, the wood frogs of Alaska do a very strange thing: They freeze. They do not freeze totally solid, but they do freeze mostly solid. Two-thirds of their body water turns to ice. If you picked them up, they would not move. If you bent one of their legs, it would break. Inside these frozen frogs other weird physiological things are going on. Their hearts stop beating, their blood no longer flows and their glucose levels sky rocket. 1 Quote Link to comment Share on other sites More sharing options...

bainbridgekid Posted December 20, 2020 Report Share Posted December 20, 2020 3rd straight WRF run to show 6+ inches for the hills of Shoreline/Lynnwood/Everett. Kind of crazy to see that. I can't remember the last time something like that happened and it didn't snow at all.

Phil Posted December 20, 2020 Report Share Posted December 20, 2020 What’s really crazy is the system that’s about to strike the PNW is what produces the big NATL wavebreak/-NAO, and even aids in the wave-2 response in the stratosphere.

Whether it’s that extreme or something more..typical..is certainly debatable. But there’s less chaos in the stratosphere vs troposphere, and w/ poleward EP flux vectors persisting and a favorable East-Asia MT/MJO transit..the odds favor a SSW of some kind to open 2021.
