Clark County actually had a ~1" snowfall on 11/21/2010. Was in the 40s just to the south.

It snowed for about an hour or so that afternoon. Mainly here on the east side.

Meanwhile the greater Ilwaco area had a major storm the following evening as the low passed (a trace of rain/snow mix that actually "drifted" to 3" if you looked at it just right in the shade)

Team Coast!!

I will never forget November 2006...I was in Olympia for a dog agility competition and that Sunday afternoon when I was heading home it was nearly 50 degrees with a warm wind blowing. Get to Seattle and it was upper 30’s. Get to Northgate and had some windshield splats, get to Lynnwood and it was snowing but not sticking, 34 degrees. Get to Everett, sticking snow except on the road. Same until I get to just north of Marysville, suddenly roads covered, by the time I hit Smokey Point there was about a foot of snow on the roads, 32 degrees, heavy snow still falling, power out, trees down everywhere...That was quite the change from 50 degrees in Olympia 2hrs prior. 

That was quite the event up your way.  It eventually hit here pretty good, but nothing like that.

What is normal?

I actually think there’s a 99.99% chance DJF ends up 0.05°F warmer/colder than average.

If you put an at least in the sentence it is certainly true.

It is truly scary that we can actually remember facts like that.

[snow_wizard]

Down to 42 already this evening.  Finally a chilly night out of this brief dry interlude.

That was a good one here.  A nice 6 inch snowfall with the second half of the snow falling with a temp of 22 degrees on brisk NW winds.  Dropped to 8 IMBY afterward.

Another interesting thing about November 2010 is it's the only time I've recorded daily averages over 20 degrees below normal this entire century so far.  I consider that the yardstick for a major cold wave.  For reference sake January 1862 had multiple days with -30 departures.

Put up the Christmas tree and Christmas lights today. Never put them up so early before. We are destined to have a great winter!

Yeah that is exactly my thoughts. Mid-late December timeframe for a legit cold and snowy pattern in the PNW.

I have a feeling this winter will deliver the snowy goods. Its -ENSO/+QBO/Low Solar. Main ingredients are in place and we are due for a solid arctic and snowy pattern. Its coming... just be patient everyone.
