Does this index attempt to quantify impact to average person? with factors like time of day/week and commute..etc? I had thought the impact is more of a factor in warnings these days?

The 18z GFS has a second cold front roaring down the Plains at d12. This one could be colder.

Need it west a tad for us to cash in. Just like that it's been an active pattern.

I was just drooling over that lol

@dailylurkerjackpot you and me

He rebranded!

That’s a little too far east for my liking…immaterial at this early juncture, but would like that to back in a tad more. Point is it’s there. Let’s do it.

WSSI suggests that DVN upgrading some counties to a warning was a very aggressive move. Given that we had a warranted daytime warning event a week ago, it's questionable if the possibility of getting a narrow band of 6-7" of snow on a Saturday evening-early Sunday warning is sufficient to prompt a warning. Sticking with a WWA seems like it would've been fine. We'll see how it goes. Sent from my SM-S936U using Tapatalk

Yup. That's a piece of the pv and nice ridge out west

You will. Snow gods are already smiling on the Mid Atlantic. Dec 5th snows are special and are only a taste. Wait til you see what later Dec and Jan, Feb and Morch have in store snow wise! That western ridge will become semi permanent.

There’s a follow up wave in there as that could pop something. It’s late on this run but shows the potential is there.

Tail end of next week looks bitterly cold. Definitely something to monitor in the coming days.

If I were a betting man I'd say the RGEM probably has the best handle on this. Looking back it more or less nailed the last system 48 hours out (just a couple counties too far south)

Mattapoisett Mauler. In 4 days, that'll be progged to be in the Gulf of Maine.

We hope and pray

Was a nice surprise this morning to wake up to a dusting here in Staten Island. Now I'm ready for some real snow.

Lol…here we go again…hope west doesn’t gets boned if this somehow materializes. Trapped and pulled back is always precarious for the area.

Amplifying ridge over west coast plus a decaying -NAO block near Hudson/Baffin and already a cold antecedent airmass equals good things happening for us usually. I think this one will be on the models quite a bit over the next couple days…let’s get the signal even stronger.

Fingers crossed

Digging trends over the last 24hr out west. Bodes well downstream for something to pop.

That forms a light anafront and then a Nor'easter. IMHO, that would form a blizzard for the NE.

Yeah, if you trace it back, it breaks off from the PV in BC and dive south and east.

If that happened verbatim, I might need to chase that in Yarmouth, lol. That looks like a grid collapser on the Cape.

west based blocking decaying around that time also argues for a storm popping up

Anyways. Def potential there. Good to see an OP run blow it up nicely. It’s been showing up on a decent number of ensemble members the last couple days.
