Beautiful morning in the Blue Mountains of eastern Oregon. It was 12F when I took these pics around 8:30am. Gotta get our winter fix somehow.

First snow of the year! Melting quick but at least a little left. Was down south picking up a new family member.

Major shift on the 12z EPS to lower heights over the West with rising heights in the SE compared to the 00z last night. Looking like a really fun mid month on through the Holidays. Perfect timing IMO!

That little hemlock looks pretty unhealthy. I keep wondering if just the top will die or if the whole tree will eventually go. A saga I have been following in your pics for a year or so now!

It is getting worse.  I hope it lasts a while since It’s in a good spot for blocking the view of our crazy neighbors.

The system leading up to New Years looks to bring a lot of needed precip to southern Oregon and northern California. Tons of snow in the Trinity Alps and Sierras. Cascades don't do too bad either.

Models keep toying with the idea of some sort of overrunning set up for the Portland area too.

Had 11 for a low this morning. Just crunchy grass and a minor frost. Doesn't look like I'm getting a White Christmas this year. But I will probably end 2020 with a decent ground pack.

Filmed in November of 2010. A historical record of the era when winters were front-loaded.

If I had moved here just 7-10 days earlier than I did, would have experienced one of the greatest November snow/cold blasts in southern Oregon. Back in Hillsboro I'm sure a handful of other years provided bigger ones.

And as long as we're posting winter crash videos from 2010, then there's this classic from Portland.

That November storm was great.  It ended up over performing, North Seattle had a good 3 inches with blowing snow and highs in the upper 20s that night.

It was kind of a wetter snow in Hillsboro but 2-3" fell that night, and some of it melted before the arctic air came in.

There was thick black ice on roads and it closed schools for the day.

The ECMWF meteograms show a low of 26 for SEA next Tuesday.  At least we will be getting chilly interludes until the good stuff comes.

I'm hoping for a re-run of this, this March. Should be good!

 

I have no idea why people are so convinced nothing will happen until March.  Nothing to support that really.  FWIW there are some Marches that have had the real deal anyway.

When it's a sheet of ice there isn't much anyone can do.  It comes down to road maintenance.

Actually there is: apply grit and/or deicer. My first Seattle winter, I was shocked at how little the streets got treated when it snowed. Last winter was my first in Whatcom County, and I was impressed at how much more grit and deicer they spread here. It makes a huge difference. (Still not as good as the Midwest or the Rockies, but at least our arterial streets get treated. If you can make it to the nearest arterial, you have it made.)

Of course, we tend to get more lowland snow events up this way, which makes the greater investment in equipment and materials stockpiling easier to justify.

It's called clown range for a reason.

Next summer we need to rent a hall and all get together and drink some beer. I'll pay 1/2 the cost of booze and food and hall. Dead serious.  Hopefully we can celebrate the a** kicking against covid!!

I’ll bring homemade ensembles and dip!

      April 2024 Weather in the PNW

      I think their 2" on August 24th 1992 is absoluetly f****** absurd. At least in June there is just enough residual wintertime cold left over at the poles to drop snow levels down to 5k feet should it be displaced south, and enough of a poleward thermal gradient still in tact to spawn strong-ish cutoff lows around the meridian line. Mid-late August is a joke of a time to get a snowstorm, even at their somewhat high elevation. They pretty much combined the strongest weather system possible at that time of year with the coldest air possible... Neither factors being very impressive nonetheless. But enough is enough. The only month I doubt they could pull off a snowstorm at all would be during July, and even then I bet the first week holds some out-there potential in the right setup. July 15-August 15 is off the table though. I think....

      April 24-29 Multi Day Central and Southern Plains Severe Weather Outbreak

      Pi-Day event had its interesting parts. Before the main bout of supercells in IN/OH, there was one lonely supercell that travelled from near Cincinatti all the way to my vicinity a few hours prior, with nothing else picking up on JKL radar around that time. Then all the later night storms developed into an MCS hitting me around 2am. Overall the Feb 28 and April 2 events gave me much more of a uh-oh feeling in the gut. Pi-Day had a ton of large hailers, and a few storms that happened to hold together a stronger tornado. Not to say 3/14 wasn't a good one though, Ohio was a surprise during that one as they weren't exactly bullzeyed at first.

      Polite Politics

      Oh, I think one side is just a bit more guilty of that than the other. Trump has taken the racist nationalist playbook and made it his platform. He is the GOP nominee and has a real chance at being the next president. No sane person can make that claim about the left and Biden (even if he is Netanyahu's little biatch). And I loathe what a lot of the left has become.
