Tim probably will end up with close to a foot and another white Christmas. Sucks living to far south for that to be a possibility, pretty much ever.

I hiked the Table Rock trail on January 5th 2014. The summit is over 4800’ and there was barely any snow at the top. 

Really hoping I can do a snowy hike at Silver Falls this winter. From the pics I've seen online it looks gorgeous in the snow.

You live at 1600’, don’t tell me you never have snow around on Christmas

Not compared to Tim. Only once have I had snow on the ground since 2011 (2015). Obviously there would have been snow in 2008, and 2007. And that is probably it since 2000.

Sort of the norm in this area it seems... its been pretty typical to have snow on Christmas during our 16 years here.    It happens more often than not.

Bro I got to move to Port Angeles. They get hammered every year it seems like. I wonder how many inches they get per year.

Wow, I think I had snow on the ground 3 out of 5 winters when I was near Portland at 1500’.  I think you usually did better than me on snow averages too.

Euro looks real nice. Great track for areas North and East of Seattle. Nice to see a Southern trend for once potentially!

Just doesn’t happen this far south. We have to wait until nearly spring when there is better upper level support. I would trade you my March 2012 snow for a white Christmas. Lol

Best chance is definitely north and east of Seattle above 500’ obviously. people near the sound and below 500’ are gonna have a tough time getting accumulating snowfall.

Yeah, but you did well with offshore flow if I recall, and Tim gets favored in offshore flow situations too. Once we get into February and March is when it seems like we do really well.

Hopefully someone scores something atleast. Razor thin margin but it’s definitely possible...I won’t be here I’ll be in Texas but definitely hoping for some snow! Here in Tacoma at 300’ near the sound it probably won’t amount to much anyways.

I am nervously/excitedly watching this. I am right on the line of 500’. Not putting much stock into it...

Hoping for some flakes to fly. Being on the northern end of the city can help in situations like these, but obviously given my elevation, I don't expect anything in the way of significantly accumulating snowfall (more than a slushy trace) unless the pattern fundamentally changes. Either way, it's something fun to track!

I will be happy if anyone below 500’ gets snow. Something tells me Randy has a good shot to score!

You’ll probably get something atleast if this verifies. Temps are pretty marginal unfortunately looks like a lot of the precip falls during the daytime. Few hours later or earlier would really boost the odds.

It would be nice to see the timing get pushed back even a couple hours. Best forcing for Seattle on the GFS and EURO is around 1-5PM and pushing that back to even 3-7PM would make a significant difference.

Also worth watching for CZ development Monday evening.

Oh, there will definitely be a PSCZ and a vigorous one, the flow out of the NNW after the frontal passage will be more than strong enough for upslope forcing. 

I expect Tim to have no less than 10-13 inches by Tuesday morning.

Here is the placement of the c-zone at 1 a.m. on Tuesday morning... this is 1-hour precip and not snow but obviously its all snow at that time.   This map better depicts the location of the c-zone at its peak.
