Day 7 850s cold air digging slowly south

[TT-SEA]

Arctic air has made it through western WA by Tuesday morning.   The SW wind finally dies in Seattle on Monday evening.  

And still convergence going on and that would be all snow.

Holy crap.   

There were crazy sideways icicles of over a foot long on signs and other objects due to the wind and freezing rain. I mean straight up horizontal. Bizarre.

Still gets there, just a bit delayed

HR 174 digging slowly south

[TT-SEA]

Temps at 4 p.m. on Tuesday... cold!  

[Perturbed Member]

Pretty good down south

[OysterPrintout]

We didn't want it this Sat/Sun anyway. 6 day slow march south will line us up nicely. What could go wrong

[Gradient Keeper]

Day 8 This is the same thing the GFS Op tried and was a huge outlier. Similar to 00z. I highly doubt this.

 

[TT-SEA]

This is an impressive run for western WA... first snow then arctic air.

PLEASE have EPS support. PLEASE!!!!

There will be a surface low somewhere at this time frame.  Models are always bad with this.  Even the King.

[TT-SEA]

Snow for just Tuesday and another system coming in on Wednesday morning for more snow.

[Cloud]

Incomingn @ 192!

[TT-SEA]

More snow moving in on Wednesday morning...

Day 7 850s cold air digging slowly south

The conflicting reports are all coming from the same person!

[Cascadia_Wx]

Very dense fog this morning and still just 33 degrees. Ended up hitting a low of 29 earlier before the fog thickened up. Fell to 31 before midnight last night, so it was a two for one freeze.

Day 9'er

[TT-SEA]

Wow!   ECMWF sticking to it guns and moving the cold air southward rather than eastward like the EPS.

Not conflicting at all. I'm sure Day 6+ is an unfortunate outlier.

4pm Next Wednesday. Leeeeets goooooo! 

[TT-SEA]

Wednesday is insane... a temp of 17 degrees in Seattle at 4 p.m. and there is snow that day.   Amazing.

 

[TT-SEA]

Looks like a -20 for Seattle... 

[TT-SEA]

850mb temp of -20 in Seattle on Wednesday evening.    Incredible.

[Gradient Keeper]

Wouldn't that be something if we had EPS support to Day 7-8.

[TT-SEA]

Temps at 4 a.m. on Thursday...

Old school. 1950 type air.

[Christensen87]

GFS needs to cave to EMCWF soon, come on Druncle! 

[Cloud]

oh my goodness. 

[Perturbed Member]

wtf

-21c 850 over PDX?

[TT-SEA]

Just majestic...

 

[Rubus Leucodermis]

Bet it will moderate in later runs but even a high in the low/mid 20’s with snow is nothing to sneeze at, particularly at KSEA.

[Gradient Keeper]

Day 10

[TT-SEA]

[Phishy Wx]
