Quite a bit of model support for tomorrow morning and yet no met has said anything about it. Interesting.

Mark saying dusting at most. Maybe wet flakes. Check out his new blog post

I'm  surprised that Mark said this  about the Tuesday storm:

 

 

"More on the big snow storm coming for a good chunk of Oregon later Tuesday tomorrow.  Time to finish up for the night here…

"

 

Quite interesting. Based on his 7 day he thinks it will mostly miss PDX?

East winds still gusting close to 30mph at Troutdale. Weren't offshore gradients supposed to completely die once the front passed earlier?

Even HIO is still reporting 33 with calm winds. Onshore flow still seems quite weak and hasn't done much to moderate even the areas in the metro away from the gorge. Hope we can get a surprise tomorrow morning. 

[Brennan]

44*F SSE 18 G32 at BLI Pouring rain

32*F NNE 8 in Lynden light snow

 

10 miles difference. Temperature profile in Whatcom County is WACK. I don't get this setup. So if the low were 20 miles further south would outflow be to Bellingham or what? I feel like a 3rd grader again when it comes to Whatcom County weather. My brain is mush. 

[Heavy Snow]

Did Heavy Snow/Acrtic Blast join Jim in the forum boycott? Or is he out making ice angels?

He's been MIA for days...I don't think he could stomach the ride anymore.  Can you blame him though?  This last month has been awfully turbulent.  Perhaps Wednesday's event will bring him back from the brink?

 

I needed some time off because the model riding was making me exhausted and I was barely getting any sleep. Now, I am fully refreshed and ready for some more snow. I got about half an inch of snow this weekend and lots of ice.

[Heavy Snow]

Models are converging on a snowstorm for PDX Metro Tuesday night/Wednesday.

The feeling you get when you take a break from model riding and find out they show a snowstorm for your location inside 2 days!

[TT-SEA]

33.5 here this morning with a dewpoint of 33.   

 

Enough to thaw things out and ensure school will be on time but not enough to melt any snow.  

 

South wind reached SEA overnight... it was 42 at 2 a.m. with S15G26.    Now that wind calmed down there its back down to 37.

 

00Z ECMWF showed weak offshore flow returning this afternoon.     Radar does not show much right now up here and it should stay like that most of the day.

[Tyler Mode]

36 here but lots more snow flakes mixing back in with the rain.

[BLI snowman]

Sloppy snow falling here now as well.

[FroYoBro]

Seems like the upper levels are just slightly cooler up in the Vancouver, WA area.

 

35 here, but pretty much all rain. 

[Kayla]

Guess someone is eating crow today..

 

Heavy wet snow here with about 1" so far over the 1/2" of ice I got yesterday. Roads are a mess but the snow is lovey!

[Deweydog]

Slop storm here. Heaviest snow this winter.

[snow maniac]

Frozen here, all the roads are like ice rinks out here. Reports of many spin outs

[Timmy]

Snowing in scappoose. Looks like precip is ending though.

[SilverFallsAndrew]

Dumping snow this morning, at least 1" new. 32 degrees, this is definitely cascade concrete slush.

[Heavy Snow]

Snowing hard here at 500 feet in Gresham. I wasn't expecting this.

If you'd been reading the forum last night you would!

Yeah

[Timmy]

12z nam says at least southern Oregon and Bend get some much needed snow!

[FroYoBro]

Looks like it will be a quick moment of fun. That heavy band is already moving out of the area. 

[Tyler Mode]

Had very heavy but brief snow in Battle Ground.  Now it's lighter snow.  Temp down from 36 to 33.  Just about 1/4" accumulation right now.

[Deweydog]

Back to a mix here.

The NAM has consistently shown most everything going south. 

[Jesse]

Heavy wet snow here and starting to accumulate. No way in hell! Looks like my dome got busted.

[Deweydog]

Good thing Mark finally lowered highs for later in the week. There's just no way Friday gets up to 30.

MOS guidance said 24 for PDX on Thursday

Rest assured, it's not his forecast.

There's that bullseye right over me again.

[MossMan]

Feels like November out there this morning...

[FroYoBro]

Wow. Beaverton School District canceled school today. They are very poor decision makers. 

 

I'm going to be working until July at this rate.

I must be on the wrong web site it's only Oregon posting here.
