November 2020 Weather Observations for the PNW


TigerWoodsLibido

Recommended Posts

Heavy rain here in McMinnville but that's about it. I woke to gusty winds during the night but nothing all that alarming. 

Haven't checked peak gusts or total rainfall from this system yet but it feels like a typical November event to me.

Hopefully Tuesdays storm delivers something more interesting.

At least I won't have any heavy storm damage to reckon with today.

Onward!

6 inches at least of snow here and still snowing.  The UW high resolution models were more accurate than the National Weather Service forecasts.

Just went out to measure.  9 inches, still snowing.  Big victory for the WRF and the UW high resolution ensembles and the high resolution NAM.  Big loss for the NWS and their automated forecasts, which have us less than 3 inches.

NAM entertains the possibility of another low striking the region tomorrow afternoon. Would likely contain another bout of localized stronger winds and a period of heavier rainfall and mountain snow.

Pretty much a non event down here. Some decent rain, but not a ton of wind. It appears the snow levels are about up to pass level around here, which isn't a good sign. 

Why is that not a good sign? We're in the warm sector, the fact that they are only up to pass level is a good thing if you want to see the mountains do well today.

48 and moderate rain this morning. Looks like the back edge of the initial batch is about through. Picked up over .75” since midnight with moderate to heavy rain most the night.

Wind wasn’t very noticeable here. Might have been some gusts 30-35mph.

When i checked the models/forecast yesterday, it seemed like the passes would be good throughout the day. It's not even 8am and the snow levels are at about 5000' already.

Leavenworth will be a winter wonderland this weekend.

That's because right now they are in the warm sector of the storm. The passes will cool throughout the day.

The warmest part of the system is right now, they will be dropping later on.

It looks like the snow level is well below 5,000' judging by pass cams.

I hope so. It would be a shame to have all of this moisture go to waste. The ski areas could really use a good season this year.

Wind didn’t end up being enough to wake me up but the rain did. Local stations reported gusts in the low 30s nothing crazy. Storms next week will probably be more significant. Have picked up 0.54” since midnight to hit 2.68” for the month. 

Tacoma WA elevation 300’

Monthly rainfall-3.56”

Warm season rainfall-11.14”

Max temp-88

+80 highs-2

+85 highs-2

+90 highs-0

That low is in better position but it is also weaker than the one going though the region today

Moisture never goes to waste. It recharges the water table whether or not it falls as snow.

Not looking good on the 26 pass though.

govt.thumb.jpg.08fd29a36fad301ee223dfb388a2610f.jpg

That’s the lowest pass over the entire Oregon cascades. And the snow level is probably just a little above it. Still easily at ski area elevation.

The higher passes of 26 look a little better.

Fwiw, looks like your windstorm will arrive here Sunday. Let’s see what it’s made of.

Boundary layer winds look decent.

Rain shadow finally falling apart up here. Only about 0.1" in the bucket in the last 24 hours. Looks like the Mt. Baker weather station is down currently. Would love to know how much snow they got overnight.

Or if it moved North and east in the sweet spot giving the puget sound a huge windstorm! It wont do either but nice to dream.

A 954mb low in the sweetspot would be.......how do I even grasp that. Unthinkable.

Calling that a "huge windstorm" would be like calling a grizzly bear a "mean gopher."

Had to look at what the Columbus Day storm came in at...960mb. 

So yeah, that would be significant to say the least.

I still have to think that the Columbus Day storm would beat it. The Columbus Day cyclone was a tightly-packed pinhole low that produced ungodly pressure gradients in the heels of a retreating high pressure system. And even still, it vastly overperformed its average potential.

The good thing about this storm is that the gradients are largely spread out along the coastline, save for the immediate vicinity surrounding the low, so that even in ground zero the pressure gradients wouldn't be skyrocketing outside of climatology.

Oh absolutely. I have a hard time believing that storm could be bested.

Anyone else working extremely hard today, with the live Masters broadcast on another screen?
