Guessing wet grounds and maybe trees that still have leaves can cause more problems than otherwise.  

Another example is that our criteria here in  Leavenworth for WSW's and WWA's is often lowered for the first winter storm of the year, so the context can alter their criteria a bit.  

Just a guess though 

.

Suppose that makes sense. Though I’d think a special weather statement would suffice for that.

How do you get a high wind watch for 50mph gusts? That’s barely wind advisory criteria which is nationally standardized.

I already a tree fall in my neighborhood today at 20 mph. However it was dead and due to fall any day tbh.

A SSW can be a game changer in the Winter, especially if it’s a major one like what this one looks like it’s gonna be. A major SSW event can overpower an El Niño like in 1968-69. Sometimes it only takes 2 weeks to feel the downstream effects of an SSW and to deliver an Arctic Blast down to the continental USA. The January 2019 SSW is an example of this. 

I’m not counting my chickens before they hatch. Want to see it get closer before getting excited.

The next big time windstorm is going to drop at least 50% of the trees in my Everett family’s neighborhood. So many tall, skinny, diseased softwoods with houses right underneath them.

Gonna be ugly when it inevitably happens.

I looked up the criteria for all sorts of advisors and warnings. Technically, the NWS is correct. I believe the reason why they issue advisories is to inform the public that there is a chance of high winds between such and such time and day. There are a lot of people who are not weather geek's like us and are not well informed about the upcoming weather. This way people are informed.

The wind direction also plays a part. South winds above 40-45mph are pretty rare here  and thus a lot more potentially impactful when they do occur since the trees around most of the Portland-Vancouver area have evolved more to deal with the east winds we get from the gorge.

That being said, this looks pretty run-of-the-mill in terms of wind setups.

its an Xmas SSW miracle

Looking pretty breezy tonight.

Had .5 today to add to my .10 total. While I was measuring the snow I got a call from a paramedic and my wife who spun out due to some ice or snow on Alpowa Summit although the road was clear when I drove out there. They went right around the time that late morning/early PM band went right throug SE WA and slammed into a car and the rail. Her and my MIl are in the hospital in Lewiston tonight. I'm home with my son who is thrilled that I'm letting him play SIMS tonight. MIL has a severed spinal cord and paralyzed and is being flown to Boise. My wife may get flown elsewhere with ankle and bone injuries. She has it rough but better.

On a weather note the winds are picking up before tomorrow's windstorm and the snow has become rain.

I was wondering if someone would know this. I bought a Tempest weather station but I really want a display that I can put on my nightstand. I like that I can see it on my phone but when I'm home, I like to see it without looking at my phone. Does anyone know a good display I can get off of Amazon or someplace else? Thanks.

Good god man that’s awful. I’m so sorry for you and your wife and her mother.

Thinking good thoughts for you and them. That really stinks. I'm so sorry.

Between pea and marble sized hail coming down at times, this is insane.  Opened the door to look outside and the thunder ripped and a lightning bolt came down just to our north in the hills, what a treat!!

Up to 2.5" today with temps in the mid 20s, nice little overperformer.

Nice, I've received 0.75" just today. Total for two days is 1.15" With the next couple of storms, I could be over 3" or more.

Low of 41 tonight. 
Humidity 62%
Light wind, downright chilly.  

[Ken in Wood Village]

Even Ryan Maue is thinking we flip back to La Niña next year.
