Think I was sitting at around 20” at this point with so much more to come...Oh the memories.

[TigerWoodsLibido 5250]

The next few days were some of the best of my life as I lived in the north/central Willamette valley in the cold air dam that was all snow except for about 12 hrs of freezing rain, then back to snow for days...amazing.

 

My heart breaks for the folks down here that missed out by 30 miles.

28 years ago today it was getting pretty chilly.

 

I was in 4th grade and we had a Christmas concert at school that night, right before going into winter break. The snow started falling in the middle of the concert. I still remember looking out the windows and seeing the swirling flakes in the streetlight, and thinking how perfect it was.

When I was 6 and had just moved to Oregon, that event made me think it would happen every year and was a normal occurrence.  I became disappointed in the subsequent years.

I remember this. It was before I became a weather enthusiast. Do you have the Seattle AFD for the November 2010 event?

IT WILL BE ANOTHER ROUND OF COLD AIR SURGING SOUTH FROM B.C. WITH

Wow, that's the first time I heard of this. Very touching.....

Massive snowstorm hit the western lowlands about a week after that.

OF WET SNOW CAN BE EXPECTED IN THIS AREA. THE WARNING AREA EXTENDS

FROM ABOUT ARLINGTON SOUTHWARD TO NORTH SEATTLE...INCLUDING

IS A RECIPE FOR HYDROPLANING EVEN FOR MORE SNOW CAPABLE VEHICLES

IF YOU ARE DRIVING TOO FAST. WATER WILL TEND TO ACCUMULATE IN

RUTS ALREADY CARVED OUT BY PREVIOUS DRIVERS...SO UP TO TWO INCHES

OF STANDING WATER CAN MAKE HYDROPLANING MUCH MORE LIKELY. DRIVE

SLOWER AND MORE CAUTIOUSLY...AND BE PATIENT WITH DRIVERS OF LESS

CAPABLE VEHICLES.

 

IN ADDITION...THE WET SNOW WILL ADD MORE WEIGHT TO LARGE AMOUNTS

OF SNOW THAT HAVE ALREADY ACCUMULATED ON ROOFS. FLAT ROOF

Bye December 2008!

[SilverFallsAndrew 13231]

That we view December 2008 as the high water mark of our modern climate is pretty sad.

[BLI snowman 5861]

It was nice but it was certainly a long ways from the 20th century's best events. Which were generally a long ways from the 19th century's best. And on it goes. We won't be approaching 1861-62 or 1892-93 any time soon, there's really no question about that. 1915-16, 1949-50, or 1968-69 are about equally unlikely at this point.

[Deweydog 13323]

So much to ugh about these days...

[MossMan 9362]

That we view December 2008 as the high water mark of our modern climate is pretty sad.

It was pretty amazing up here with both duration and snowfall as well as temps...no so much down there?

ON HIGHWAYS...STREETS AND UNDERPASSES. IT WILL ALSO CAUSE INCREASED

FLOWS IN SMALL STREAMS.

So much to ugh about these days...

 

Sounds like someone has the post cold-phase blues...

[SilverFallsAndrew 13231]

It was pretty amazing up here with both duration and snowfall as well as temps...no so much down there?

 

Temps weren't as exciting down here. I think SLE hit 14 and EUG hit 10 on 12/16/08, but aside from that first cold shot temps, especially low temps were especially underwhelming. PDX never got below 20. 

 

There was quite a bit of snow Salem north, If you count Dec 14-25th as one sort of big event, it was the best continuous stretch for snow of my lifetime in the valley. Though in the Salem area 1992-93 and 2016-17 were probably better overall winters. 

[Deweydog 13323]

Sounds like someone has the post cold-phase blues...

I prefer to refer to it as a synaptic tree-killing serotonin drought.
