2/22/23 - 2/23/23 snowstorm totals

 

I love how these maps cut off Oregon City so nobody has to see our pitiful .5"

[SilverFallsAndrew]

A couple of fun obs. First one is a few miles away as the crow flies and a couple of ridges over and similar elevation. . Second is just east of here on the ridge above the Molalla River. 
 

Wind has backed off here and it is down to 16. 

[Timmy]

Did the gem just not run tonight? Not running on tidbits for me.

[SilverFallsAndrew]

GFS wants to move the ridge over us and flatten it in the long range… I think the CFS did this a few days ago and then retrograded it mid month for a March 1896 redux. 

[Roman-Dallas Snow-Zone]

Cold north wind pretty blustery. 22f and DP is 15. Had 4" at the house which is on the lower end of what I woulda liked but I would say right in the middle of what models showed for my area.. overall best snow this season. Looking forward to more chances over the next week stay frosty!

9.5 - 14.6 inches in Tillamook. What the hell. Ridiculous. 

Also 13 inches in St Helens but @BLI snowmanin Ridgefield had quite a bit less I think and the distance between those two isn't much. 

Yeah that's nuts. Had about a 4" storm total here with the depth peaking around 3.3".

@IbrChris told me he had 5” in Columbia City on the Oregon side.

White on the roads tonight. I left my house to go to Lewiston at 5:20pm and everything was clear...even a bit sunny. When I finished my mtg there around 7:30, it started to snow. The wind was making it tricky to see past Clarkston, WA and Alpowa summit was covered in new snow. Not too deep. But very hard to see the lanes. Thank goodness for rumble strips. I took a break at the summit for a few minutes and drove behind a snowplow the next twenty or so minutes home. A benefit of living on a state highway for sure.

 

This was not in the forecast and it was a surprise but also a bit of a white knuckle drive home. Took a lot longer than normal and you could not see the lanes before it was plowed. Wind was blowing from the west too.

I have .20 of new snow just in the last two hours or so. Second picture was Alpowa.

Probably means it's accurate, the snow dome is in full effect.

[SilverFallsAndrew]

I would love to see PDX hit at 24 by midnight to tie their record low. Dewpoints and sky cover are great from Corvallis north, we just have a little too much mixing right now.

Looking for some advice from you kind folks. We're pretty new to the area and want to make the drive out to Leavenworth this weekend. Do you guys think I-90 will be passable with a Subaru Outback with snow tires? Don't wanna take any serious risks, but also don't wanna cancel for nothing. We were thinking of leaving around noon as the snow tapers off, but it looks like at least a foot will have fallen over the pass overnight.

 

ABSOLUTELY  you will be good.  Be careful on blewett pass. I've done that drive about 200 times and blewett can be really icy.

I'm in St. Helens and we never had close to that on the ground at once (more like 5"). We started with about an inch Wednesday morning and it snowed most of the day with little additional accumulation until after dark (temps around 33/34 degrees during daylight hours). So maybe they're counting the snow that fell rather than snow cover.

It's also possible they were measuring from a location in the hills, rather than down near the rive where I live.

This is OT but I’m observing some of the craziest thermal contrasts I’ve ever seen here. We decoupled and dropped from 80°F to 54°F fairly quick after sunset, but winds aloft are increasing and starting to mix back down to the surface.

The sensor at the SW end of the property is currently reading 71°F, while the one on the NE end (which is only ~200ft away and 50ft lower in elevation) is 56°F!!

I walked between the two and it’s crazy, hot spots, cold spots, etc. You can feel how much warmer the puffs of wind are compared to the antecedent air. This has happened before but never to this extent.

sorry lol, just can’t help geeking out over this stuff.

Agree. Just be flexible on timing if they’re super worried. Blewett is the worst. Stevens can sometimes be a better option depending on the situation. In the summer I take stevens often it’s such a more enjoyable drive and only one summit, though it’s about 15-20 min longer than if I went 97/90.

Phil, is late March a lost cause out west? Looking for some hope…

Haven’t you already had enough blessings with more of the real deal next week?

Alright, for the final time until the offseason, I subscribed to Pivotal weather plus. 

18z EMCWF. No bad @SouthHillFrosty

Yeah, judging from radar it was heavier but not that much heavier to our immediate west. At least near river level.

Crazy that Columbia city could have 5” and st Helen’s 13. They are less than 2 miles apart

[SilverFallsAndrew]

The GEM looks chilly, and it sends the bulk of next weekends trough into the Great Basin. Looks like an all timer.

Unbelievable.  They need to own it.  So many of us on the forum were talking about how ridiculously conservative they were being with the forecast.

They aren't doing there job.  

[jcmcgaffey]

Lots of potential next week but could also be a very tortuous week with lots of low to mid thirties rain/snow mix with nothing to show. In the end excited for the fun weather watching.

Dew Points remain below freezing the majority of the time. Your missing that

A step back again on the Euro 

Edited February 24, 2023 by SouthHillFrosty

[Gummy]

The pullback continues. RIP.

[Weiner Warrior]

Euro coming in a bit warmer than GFS.

[Weiner Warrior]

Winter canceled... bring on 100 degree summer days.
