6z really hammers SW WA Wednesday night with that same low spinning up that first appeared on the 18z GFS and the 0z Euro really upped the ante on. Nice to have an actual specific feature to track and watch rather than just hoping to get lucky from spot showers in an overall chilly pattern. Models won't have a good handle on how well that low holds together or tracks for a while but the North side of that could easily see 2-4" if it does hold together well IMO.

Yup. 06z GFS gives Seattle snow while the 00z barely had any. Wednesday night is worth watching now.

6z GFS has noticably more moisture around both Tuesday night and Wednesday night for the Puget Sound region than the 0z. Always a good sign to see moisture trending up as we get closer in setups like this. Models always struggle more than 24-48 hours out with the small mesoscale features that bring most of our potential snow in these borderline scattered setups.

It’s a Presidents Day miracle
