Let's get real about one run of the GFS.  Yesterday's 18z run had 2.16" qpf here for this storm only, then at 0z it had only 1.29", before going back up to 1.91" at 06z.  Now it's back down to 1.55" at 18z.  I'll bet it's back up significantly again at 0z.

Hope we aren’t doing a Jan 2022. Ended up an all timer here, but rug pulled many in the final 24

Not sure that was truly an all-timer there. There were discrepancies in amounts down there.

I still think many here are on the verge of bridge jumping, :cliff:.  They can say they are just kidding, but we know better.

If en masse everything moves like that together, you have to question the validity of the input grids/data initialization.  That said, this looks like noise to me

When you say everything, you must not mean the 18z NAM or the 18z HRRR, which didn't.  Whether or not they are in their zones.

I'm just speaking to the reactionary crowd song.   "As though" - that's how they're sounding.  I saw GFS S followed x too, y too posts ... it's nerviness controlling people's reaction without being analytic about what they are seeing.  Hence the "if"

I don't really care honestly.  Folks will engage how they want. I'm just offering that observation - take it or leave it.  But the 12z and the 18z as I demoed above are utterly meaninglessly different at 42 hours.  Ferocious combination of blinding blown choking snow rate hurled along by possible grid contending wind gusts.   Good luck

check out the hi-res RGEM..24"+ SEMA

I’ll have to take a look. I mean, it’s tough to be really concerned south of Boston, but I’m remembering several big ones in the last decade that have shuffled SE in the final 24 and left a lot of folks hanging. Hope we can avoid that here

I wouldn't be surprised if the GFS was actually a bit too low with QPF, especially along the QPF gradient (like Ray alluded too earlier) but too me it seems the GFS is way too quick in shutting down the CCB. I know the system has occluded but its shutting things down a bit too quickly with 850mb winds coming in at 50-60+ knots. Yeah its more of a northerly component but there is still a moisture fetch from the Atlantic.

The issue is they're all cutting back. Plus the closer in we get to go time, each model run is is more accurate than the last.  It's not like having a bad run 5 days before the storm. It's supposed to start snowing in 24 hrs.
