Part II- January 2020 Obs and Discussion

Here's the 3km NAM through 9AM tomorrow.

 

looks like the precip shield is in-between chehails and Olympia currently. What time do you think it'll move north?

[Jesse]

12km NAM shows a low developing this evening over the Olympics.

 

Makes things much more moist for snowfall tonight over the Central Sound.

 

Also shows some green stuff falling out of the sky in that city that’s not seattle on the southern rim of the planet.

It's really just a glorified futurecast radar. It can do well if the feature you are tracking is already showing on radar and you are looking within a few hours but anything past 4+ hours or if the CZ/band/etc. is not already showing, it struggles.

 

I only post it when it shows something good because of course that's how the world works. 

 

Speaking of cherry picked maps to post.  I saw a post that said Tim got banned.  Is this right and something worth reading the sad snow drought plagued posts to check out?

 

BTW-  I like positive cherry picked maps.  positivity baby!

Is that in Tajikstan or Uzbekistan>???

Raining in downtown Seattle

[luvssnow_spokane]

WOW... huge improvement on the NAM for the puget sound. Will this verify?!! Dunno.

 

[Deweydog]

NAM keeps gradients down here southerly...... UNTIL THE END OF TIME.

[luvssnow_spokane]

I might get to 40 today... EURO was way to cold if that is true.

[Deweydog]

This news broke last night. The Euro was WRONG.

[TacomaWaWx]

doubt it...bouncing between 34 and 35 here close to the sound. Should be a snowier night for us south of Seattle.

I heard it rains in Seattle a lot.  Send it over here.  I'll use it for snow.

I guess the 1996 REDUX is on the table. Thank the snow goddess. And lets not forget the region as a whole please... Push the goodies to our brothers and sisters down the road a piece as well.//

Yeah was drizzle in Bonney Lake a while ago. Amazing how 500 plus feet means nothing in the swamp.

[Jesse]

ALL CAPS

That’s because the arctic front is hung up on 520 bridge.

[Deweydog]

Only 8 in Omak as of noon after a low of 5 with the strong outflow. This thing was oriented perfectly for them.

 

Coldest outflow there since the second push in December 2008 I would guess.

[SouthHillFrosty]

We can hope the nam is not alone for tomorrow with the surprise low for the ps

[SilverFallsAndrew]

Wife went out and scraped the dish. Facetimed and said its snowing moderately. She didn't measure, but it looked like at least 2", maybe more.

Yet another TOP TIER 21st century airmass. Flatiron is slapping a glitter label on his pee chee for this one as we speak.

I better get 10 inches from this or I'll be pissed

Yeah it's still 4 below at the nearest obs to my cabin. You just dont see that to often during the afternoon.

Seriously.. drove from south seattle up to 185th. Once you hit U district there was snow all over the trees and ground

Would have been 40 degrees colder in 1968.

That made me laugh, but seriously today is an example of what weak sauce our arctic fronts are around here. Super shallow airmasses that get hung up for hours on low lying terrain. When I lived in NE Oklahoma it was fun tracking the progress of the fronts. Usually once the arctic front went through Wichita it was about 2-3 hours before it would arrive. Would get some insane temp gradients too. In December 2008 there was one day that was 72/18 and the next day was 18/14. Pretty dynamic stuff, of course overall it is not a great place to live if you can help it. 

[Deweydog]

NAM LOOKS WETTERER.

[wxmet]

Looks like we won’t manage any days completely below freezing either. Might as well bring on summer at this point. Does this forum have a panic room?

[SilverFallsAndrew]

Looks like the low level arctic air has made it to Tri-Cities. Winds have switched to NE at Hermiston and Pendleton now. 

[weather_fan]

If the arctic air has reached Seattle was has caused the temps to drop? The CZ is long gone.

. I’m just south of the space needle and it is dumping snow now. Can’t even see Queen Anne. Been snowing off and on all morning. I am also on the top floor of our building (8th floor).

[Jesse]

Wet flakes are flying at Council Crest, but nothing sticking. Tells me we are a long ways from snow anywhere close to the valley floor. Granted precip rates are pretty anemic at the moment.

[FroYoBro]

It is still 38 here. I’ll update everyone again when it is 38 an hour from now.

[Ice_is_Everywhere]

Light snow falling in West Seattle. Currently 36.

[runninthruda206]

wait there is a low developing tonight?!

Light snow now falling downtown. I can see the heavier action from my office building near the Space Needle.

Northerly flow at 520 bridge and southerly flow at I-90. I think this is the frontal boundary, but the tight temperature gradient has diffused out from yesterday. 

 

Yesterday temperatures were dropping 10 degrees in 40 minutes as the front moved through Whatcom County. While we won't see such a sudden drop, temperatures in Seattle should cool throughout the rest of the day as northerly flow picks up. 

[MikeInEverett]

Hope the NAM somehow ends up being right

A lot of places might tomorrow, and possibly Wednesday.
