Better explanation than Cliff Mass, at least for us non-meteorologists.  Thanks, gb!

Not included (because it happened after the article) was the closure of the Grapevine section I-5 (descent from the Central Valley to LA) on Wednesday night.

"Unprecedented"? Not so much according to my memory, and a little online searching. Oct 12, 1962 had a storm come ashore which had gusts to ~120+ mph in Corvallis and over 130 mph at the coast. I was in Eugene at the time, and walked home from school during the storm (2nd grade maybe?), and I remember judging whether it would be "ok" to walk under partially downed power lines.

However, having said that, I'm sure this was quite a blow. Just not unprecedented, not even in recent memory.

^ "unprecedented" drop in barometric pressure (at sea level) ever recorded at Crescent City, California, which (if I am understanding the text in the article correctly) broke the record for all of California.

as to wind speeds: the Columbus Day Storm of 1962 recorded higher wind speeds than this most recent event, as did the storm of December 2007 ( link HERE ).

Inaugural Day Storm (1993) wasn't quite so bad ( link HERE ).

How interesting, thanks for that. I'll have to go through this and look around a bit.

When I worked for the FAA, and before they consolidated the Flight Service Stations, our local FSS had two altimeter setting indicators as part of the weather station instrumentation. They indicated the local atmospheric pressure in inches of mercury. One of the indicators had small scratch marks on the display bezel indicating the lowest reading(s) observed. I recall one time in the 80s, I think, when one mark was scratched below the lowest number on the dial, at 28.00".

This was the time when the FAA was testing a new aircraft for cold weather operation and they had flown up to Alaska, but the weather there wasn't all that cold. They stopped here (ND) and it was so cold that they couldn't get the aircraft started for several days, maybe a week. I wish I could have grabbed one of the altimeters, when the FSS was decommissioned, but I couldn't.

Heard from my sources that it snowed a bit highways east outta LA. In those areas you are likely to get cars chaining up and driving 60 mph over bare pavement.

Believe it or not there are still SOBO's on the PCT.  Reading the PCT page it sounds like they are having a humdinger of a time

Looks like it was almost a direct hit on Mount Shasta. The glaciers there are a net positive in a world of retreat. For now.
