Icon looks a bit strung out. 

beat it

[Ji]

the icon was showing some horrible solutions that past few days so this is a good sign right?

[LP08]

GFS weaker with the initial NS SW through 96.

[clskinsfan]

It has the Sunday appetizer as well. 

Way colder this run. 850 line is through the middle of MD. Was in PA at 18Z.

[stormtracker]

GFS with differences vs 18z...shouldn't be as (drink)...amp'd

[psuhoffman]

Way less ridging this run

[clskinsfan]

Snow into Winchester at 120. 

[Ji]

the 850 temps at 114 hour at 00z are laughable differences with the 18z at the same time. the line is like a 2 state difference

00look at the 850 line at 18z

00z

[clskinsfan]

Light snow into DC around 126. Heaviest stuff to the south though. 

[clskinsfan]

132 Boom. NOVA/DC special incoming. 

[LP08]

Mod snow moving in by 132

[stormtracker]

Most of us already knew this, but this storm is frustrating af and honestly, we probably aren't going to know what's what until like 48 hours beforehand.    It's like a snake, keeps wiggling back and forth, but within a certain zone

[LP08]

135 Heavy stuff out by Winchester.  Comfortably snow everywhere.  Sharp cutoff through MD

[SnowDreamer]

Good snow 132, 135!

not there yet, but this is good news.  If we can get a hold for like 4 runs in a row...

[Ji]

just stunning differnces in runs between 18z and 00z lol. Its not like this is happening at 240 hours either

[Ji]

still to strung out for my liking. Get that a bit stronger without the ridging lol and we can get our pink back

[jaydreb]

[Solution Man]

GFS coming around to Euro and Icon like

yea--that was kind of the worst boom ever. The post was way better than what the model run showed smh

[stormtracker]

eh, not as great as I thought, but definitely not a disaster that was 18z

Why what’s wrong with it.  It’s blue for you and me and the others 

[stormtracker]

Yall gotta know when to call BOOM.  Gonna give people in here a heart attack.  That was more like a "pew pew"

[Ji]

you guys will like the para better. Thats more boom

Yeah. That has to be the thinnest stripe of accumulated snow I have ever seen on a snow map. This one is going to be a heartbreaker for someone.

That NS wave really makes this harder then it should be in this setup. And that’s the kind of crap you can’t see from range. But even with a weaker solution it still damages the thermals ahead of the southern wave. If that NS wave simply didn’t exist that would be a really simple WAA snow setup. 
This before the NS wave is still pathetic for an airmass that was directly from the Arctic but it’s decent.  It’s enough. 

but look what the flow under the NS wave did...

we’ve lost the mid levels before the SS wave is even approaching.  Now we have a double bind. We need cold to press back in but we also need an amplifying wave to get good moisture.  That double bind is why we see such a limited scope to the snow on most runs and why this won’t be the kind of expansive snowstorm it could be in this setup if the NS hasn’t wrecked the thermal profile in front.  It also doesn’t help that even a direct shot of Arctic air isn’t really all that deep to resist a fairly weak wave.

Looking at the black and white CMC doodles, it appears it will be South of the 12z run

It's better than nothing, but not heavy snow.  I'd rather have that than the 18z, that's for sure.
