Historic snowfall, a bit more to come today

NWS has extended a Winter Weather Advisory for the East Puget Sound lowlands until noon above about 500 ft for an additional 1-3" possible. Winter Storm Warnings continue into the evening for the mountains with no ETA yet on I-90 from Ext. 34 to Ellensburg reopening. Snoqualmie Pass is measuring snow accumulation in "feet" of course.

Higher elevations like Wilderness Rim or Eagle Pt.-SR may not switch over, just run out of precipitation..eventually. Most should see a transition to periods of light rain or no precipitation this afternoon. Gap winds let up overnight and light southerly breezes have taken over. That should greatly help to usher in warmer air aloft.

As expected, appears to have snowed for most, if not all of the overnight period. Depending on exact spot, 24 hr snow totals at noon are likely to be in the 12-18" range. Wow! One for the ages. I was up here during Dec'08-early 2009 epic snowy winter. We tallied ~30" that entire winter. Feb-19 alone has exceeded that.
We'll update on the rest of the week later this afternoon or evening. Stay warm and safe!
