Yeah I get that too. Night shift on and brightness as low as possible. And then try not to make any noise out of excitement or anger.

It’s possible it may not stop snowing until April.

As you’d expect, the stronger the low the stronger the tuck.

Yeah...any pattern that gets NYC-PHL-DCA excited is generally not great for us. Lots of scraps and sloppy seconds at best.

Heh...that looks like the para gfs run from 00z.

That s/w is turning negative and that is a potent tight vort. I thought the flow in the northern stream was looking a little flatter with another s/w modeled further south this run.

Beware the shitstreak on this gfs run.

I’d take that solution and run too.

The paraplegic GFS has consistently looked like the most likely outcome.

I’m glad we learned a lot from the clown maps a week ago.

You’ve got multiple events there.

We’re outside looking in right now, but you know how it goes. A little less confluence and a little more amplification south and it won’t take many bumps to get a fronto band up here on the north side of the QPF gradient. Odd are against it, but we’ve seen it before.

Kinda, sorta, not really.

Pretty much. It’s going to take a lot of Kraft tugs to get this one enough north for a big hit so I may need to cheer on the Cam pick 6.

I’m in the all or nothing camp. If it’s not going to be big then give me blue sky and SNE cirrus.

It was mostly after 12z.

Looks like a lot of big hits up here based on the eps individual modeled snow depths at 144hr. We wait and let it play out.

Here's the last 3 runs. Quite a different look vs 12/18z.

Southern stream is pretty amped this run and the confluence shoots right on out. Not saying it's right...it's the German model for god's sake...but I'm not surprised it's way more N this run based on the upper air.

GFS paraplegic last night looked somewhat similar (edit...bad take here...similarly amped but they get there differently)
