Ended up with 1.5~2" of snow here, the temperature is back up to 35.6F and there's a bit of melting going on but not as much as I would have expected. The sky looks totally clear now and radiative cooling is likely helping holdoff the melt. Could be a very icy morning tomorrow.

Ended up with around 2 inches here as well. Can you imagine how much snow we would have got with that track and the amount of precipitation if there was cold air to draw from  or arctic air in place.

I see he edited the response now. Wasn’t attacking him or anything so not sure what’s up.

Yeah, I was thinking about that, I recorded 42.4mm of precipitation today not including whatever unmelted snow is left on the gauge. We'd probably be talking in feet of snow rather than inches had their been Arctic air in place. Although some places would get a pretty nasty hit of freezing rain in that case too.

I think this may have been mentioned already, but the 18z looked real nice in the long range. 00z evolving in a similar way.

Stronger with the SSW as well.

Easily 15–20" at KBLI if today’s storm had been 100% snow at temps cold enough for it to be dry snow.

Just measured 2" on the snow table, what a fun event! It was an entertaining afternoon since I had family spread across western Washington. Someone was reporting snow while another's basement was flooding from the heavy rain.. meanwhile I was sitting at 58 degrees and dry. And most everyone, at least briefly, got their turn.

The timing was ideal too: I was home from work but the kids were still awake. We probably disturbed the neighbors hollering and singing on the deck during the heavy bands of snow.

The excitement and weather updates here enhanced the experience. Cheers y'all

Thanks for the update... I was about to go out and measure.    Looks like about 2 inches to me.

Back to looking at models, some nice mountain snow for our Cascades according to tonight’s GFS so far.

I may be one of the few people here who thinks it might snow (in the lowlands) this month. Note I said might, not will. Basically, I don't think the models can be trusted very much more than a week out, and the implications of that mistrust cut both ways.

Called it!

SEA had quite a day today.  Record high, record precip, and snow.  They crashed from 59 to 34 during the passage of the cold front.

Today makes the 4th freakish warm spike we have had since November 1 and most of those had the bottom fall out right afterward.  Pretty bizarre.

So the SSW is confirmed and in progress now? Just want to know the details of it. 

The SSW did happen earlier in the month I just checked.  It spiked and the polar strat temps have remained above normal.

By the way, today is the answer to the question of why non-snowy clown range forecasts never bust while snowy ones almost always do. Non-snowy clown range forecasts can and do sometimes bust. None of the major models were indicating lowland snow for today a week ago.

In fact, I would guess that if one did an analysis, most of it comes down to emotional involvement. Most people here (including me) want snow, so place more importance on model runs showing it. Then when they bust, we tend to remember the disappointment.

So it happened already? The models I thought were stuck at hr384 still with the bulk of the west 10mb winds. No?

No.  Wherever Jim is talking about is not a big SSW event.  What sp many forecasters are talking about might happen in early January.  And if and when it does, no guarantee the cold air heads our way, but there is a good chance it would

Probably going to get a cold/clear night out of it too. It cleared right up behind the front over here.

That does happen so easily down here.    Clouds will linger all night and temps will probably go up a little in the Seattle area.

With nothing of interest having happened here yet, let's hope the EC can throw us a bone.

I actually enjoyed this snow event as much or even more than some events that dropped more snow, got colder or lasted longer (ahem ahem December 2009 in Seattle). 

I think a big part of it was my expectations. The models never agreed on how much it would snow here, showing anything from a trace to six inches. Knowing that it was a marginal situation, I didn't expect much at all, so when it actually started snowing it was a great surprise.

The snow was pretty heavy so the landscape transformed quickly, and it happened while it was still daytime up here, so I could take a walk in the forest. Then of course there were the dynamics...the sudden change from rain to sleet to snow, record high temperatures and precipitation. 

If this had happened in late February after a snowless winter, I would be a little disappointed. But as it is, it makes me look forward to January hopefully having some more fun events that also get people further south snow and cold. I don't even mind much that it's melting now since it was such a fun day.

Something “of interest” could happen sooner than you realize. Clown range has never exactly had stellar accuracy, and that is even more so now that the models are starved of initializing data.

It's called clown range for a reason.

This band over my area now is not a c-zone... it appears to be the back edge of this system and its moving to the northeast.

Its not snowing here.   Its barely doing anything but what is falling is drizzle.  It also seems to be warming up a little.
