PNW December 2022 - Part II

[Tenochtitlan]

Wow, the melt here was incredibly dramatic. BLI rose from 33 to 48 in twelve minutes around 6 AM this morning. Almost all the snow is gone now save for the piles and a bit on the grass.

I actually like that it ended so suddenly, it makes the event more memorable. It's kind of like we were teleported to Minneapolis for a week and then back to the mild, rainy PNW. BLI eked out a high of 31 yesterday as the cold air held on in the lower levels, so that makes five sub-freezing highs in a row, along with four highs of 17-22 in a row, 8-12 inches of snow, and about a half-inch of ice. The snow came at the perfect time to be able to enjoy it for three very cold days and one more cold day with a regional ice event that would have been much more destructive without the sleet. Definitely one of my favorite weather events of all time!

Climbed as high as 34.3F earlier, back down to 33.2F. Slushy mess outside. That offshore flow not going down without a fight in the PDX metro.

Don't know what the situation is like east metro but I can imagine the Gorge may be looking bad about now-- heavy moisture and still in the mid 20s.

Seattle just warmed up so quickly that single pane glass is fogged up. Never seen this before.

The snow melt has been incredible. Unfortunately.

Looks like a proper winter storm out that direction.

Kind of fun watching the ice plug break out of my rain gauge just now.  With some likely undercounting due to the rate of bucket tipping, it shows 0.56" (since the start of ZR) and an instantaneous rain rate of 25" per hour.

[MWG]

46F with rain/mist and I'm actually not mad about iit. Wish it was snow but still kinda sets the mood for Christmas Eve. We aren't into making a big dinner for today since it's only me and my husband so we are making beef stew. 

[Phishy Wx]

up to 21 with ZR, some sleet mixed in too

 

 

[Deweydog]

Ice pile at birth.

[TT-SEA]

SEA at 54 now.    Looking forward to those southerlies punching though here to completely clear the roads.

[Sandy rocks]

Dreary dark day here. Very wet. Looks mixed,

[MWG]

 58F for tomorrow

[Doinko]

PDX is at 33 still

 

[Rubus Leucodermis]

Still looking like Tiger gets a 60-burger for Christmas.

[TT-SEA]

ECMWF looks fairly average overall over the next 10 days... normal is around 45/36 at SEA in late December.

 

[Cold Snap]

Up to 45.4 now. Southerlies have kicked in. Snow is melting rapidly here now.

[Requiem]

What is with our strong lows these days lacking jet support the whole way through

[Rubus Leucodermis]

Euro says torchy for a few days then climo.

Mild torching then climo is more accurate.

That looks extremely cold to me!   Is that for Bozeman?   

[Cold Snap]

18z GFS showing a Willamette Valley windstorm next Tuesday. 12z Euro showing a Puget sound one. I have a feeling someone is going to get hit with big winds next Tuesday as the models have been showing this storm for a few days now.

We've had more icing today than at any time since the event began. Still 33 here and our driveway is a skating rink. And we're usually mixed out faster than the east side.

We could get an 80-burger.

I got "weenied" for mentioning this earlier, but 62º is EUG's record daily Xmas high, from 1980. Seems like there's a shot at it.

PDX had a 64/60 day on 12/25/1980!

Certainly possible. The GFS is going for slightly cooler temps in the upper 50’s, but the Euro is probably closer to reality.

Yeah it’s kind of the perfect conditions for an insanely warm day. Warm airmass, mild morning lows, probably a lot of sun breaks, and southerly winds ahead of an approaching front to mix out any inversions. Monday should be fairly warm, and then by Wednesday back down toward normal. 

[MossMan]

Lit up like a Christmas Tree! 

[Phishy Wx]

Heavy Sleet, Snow and ZR currently.  up to 23.

[SilverFallsAndrew]

Unfortunately the next few days flush out any meaningful cold from out side of the globe. The jet suppression the GFS keeps insisting on is much less interesting as a result. 

[TT-SEA]

My wife asked if this warm up and rain was going to turn to heavy snow again like it did on Tuesday.   She hasn't been following along.    

[Snownerd3000]

Anyone following the 18z?!

[Phishy Wx]

this is going to be a mess when the melt starts, snowpack inching toward 1.5' IMBY, deeper drifts.  berms along the street will probably cause some flooding.  street doesn't have drains, just curb split flow offs and parallel drainage ditches, all these are frozen, covered and/or blocked by plow berms. also worried about ice dams in my gutters. we're headed to the east coast on Tuesday for a week so if got my landscaper on call to come over and snowblow (if needed) and alleviate any potential driveway flooding so the pet sitter can get here

[TacomaWx]

Absolutely no ice or snow left…was mostly still in tact early this morning. Feels so warm out there. Pretty wet to 0.77” since midnight over 4” on the month.

Did you tell her Matt says MLK day is our next chance? 

[Snownerd3000]

W OR snowstorm followed by fake cold to start 2023

[MossMan]

Ran down to Smokey Point to pick up the Christmas pizza’s and I noticed the potholes are already starting on some of the roads! They do not like this fast freeze/thaw stuff. Also people are driving like there is still snow on the roads, either 30 over or 30 under the limit! Fun! 

[NWbyNW]

Starting to get quite breezy and gusty here.  Had a gust of 18mph.  Sustained winds around 6-10mph here around the port at Everett. Didn't expect wind.

Amazing what a night does.  Yesterday was 25F degrees and everything was covered in snow.  Today it is wet and windy and 47F.
