PNW February 2023 Weather Discussion - Meteorological winter finale


Recommended Posts

I would give this winter a B+ so far for this area assuming the Tuesday event comes through with 1-3” as expected and we don’t have an epic March. The only thing missing was a big ticket snow event, but we had lots of minor snow events, plus one unforgettably cold day in late Dec with highs in the low 20s and strong winds.

At this point another strong punch of cold air next week looks a pretty strong possibility thanks to the MJO wave.  The only bad thing is this could trigger a WWB which might trigger a Nino.  Still a chance we only go to neutral ENSO though.

This winter gets decent grades for cold.

I'm hoping for a neutral winter next year. Would be awesome. Hate Nino's.

Melt-a-thon has been happening now but very slowly since there is no wind IMBY but still have probably 1/4-1/2” on grassy surfaces. Honestly not that bummed this didn’t work out since there’s a chance for something big tomorrow night and in the end it was still a nice event with 3/4” of snow.

Looks like Seatac recorded 2.0 inches of snow last night, with 0.28 inches of precip.

It was at 32 degrees and snowing from 12:35 AM to 4:25 AM.

 

It’s rare that SEA gets more snow than I do and even more rare when it’s an event that is widespread. Just goes to show how weird this setup really was.

I agree the cold was good but I am at a C- due to getting skunked time after time with the snow.

I'm sure you have gotten snow there.  My total is getting near 10 inches and I'm pretty close to there.

It does look like a CZ is starting to form right in that area on the radar.

ECMWF shows the same thing... that is also when the SW wind gusts peak out here in my area.   ECMWF is showing gusts to around 40 mph for 3 or 4 hours this afternoon out here.

7.6” here so far this winter as of this morning. 

It’s been fun having all the chances but would be nice to get a good dump of four or five or inches before it’s all said and done. I know I’m getting greedy because the last few years have been so good, but hey…

If my math is right that's around a 7:1 ratio. So almost split the difference between those calling for a 5:1 ratio and those saying it would be closer to 10:1. Not too shabby for Feb 26.

We’re up to 72.9” of snow since December 2016 as of this morning. An average of 10.4” per winter the last 7 years. We will bump that average up a little bit too soon. Going to suck when our luck runs out inevitably.

The worm has really turned this winter.  We'll see if it holds.

Sure hoping it does because they need to replenish the aquifers in the central valley and the reservoirs being full and a great mountain snowpack aren't going to do that in just one year. 

Wpuld love to see the Colorado River reservoirs get in on that action too, but that's a very tall order.

The 12Z EPS is pretty emphatic about the block lifting away later in the run... seems like this would lead to a wet pattern.

18z NAM showing a band of snow moving through central puget sound tonight.

EDIT: The 3km shows a nice one for Portland as well!

Been paying attention to tomorrow night but hadn’t really focused on tonight much. It’s not as much of a slam dunk but we could get 1/2” or so. Just very scattered so hard to pin down. 

Yea it’s jumping around. Significant pull back on the 18z for us

After just getting a rain/snow mix last night, this would be cool for my area. It was just too warm somehow.

Didn’t mind getting no snow accumulation at all last night as long as Tuesday’s system does decent 🤞

About two weeks ago when the Euro was only showing .5 inches here I ended up with 3 inches. Maybe tonight can over perform!

Similar here, that bit of snow we had last night has held on better than expected. Wish we could get this sort of pattern after a better transition event. Looks like some convective showers on the way.

Could be good for king and pierce county…we will see what radar looks like in a few hours. It’s pretty cool how we’re basically maximizing potential snowfall with these systems like the one last night and the next couple nights coming up. Heaviest precip set up just at the right time last night and will the next 2 nights. Lot of times we aren’t as fortunate.
