WV sure looks like it's going to try and saturate into a deformation band. May have a little dry air issue near here, but overall it should keep snowing into the early afternoon.

We got our 30 burger, it just happens to be at Jeffreys Ledge.

They were reporting blizzard conditions on my drive in and I can say it was not that bad. The roads were terrible and there were branches and wires down, but the vis was manageable. It's almost more of a fog than snow reducing vis to my eye.

I haven't seen any sleet obs so far, just 1/4sm +SN. But I wouldn't be shocked if there was some graupel in there, because it's pretty convective.

Depends how many drinks you give him first. He's about 4 miles from the office.

For Ginxy's eyes only...the western Maine shelf buoy is at 27 ft right now.

@tunafish is definitely closer to the water than me, I had another 1 or 2 inches accumulation around the same time. By the time you make it as far west as GYX you're getting into the double digit amounts.

They officially were at 4.5 with the 12z ob. Going to hard pressed to get another 8 today I think.

Very convective. Look at that stuff feeding in off BOS. EEN/AFN now 1/4sm. At the very least this band should drop a quick 1-3" or 2-4" as it lifts north.

30 burgers ship sailed when the mid level lows got strung out. You need a well organized secondary AND a stall/loop, and we just didn't have that here.

I think they do well for situations where the entire column is marginal with those 32-34 surface temps. Locally the temps stayed around 32-34 but it was a pure snow sounding above that.

Like many products, good in some areas, not in others. It was terrible around here, with forecasts of 2-3" but we're easily 6+ OTG away from the coast even with compaction.

I'm never going to jump on anyone for coming up with a soundly reasoned forecast, as long as the headlines are messaging the right thing (i.e. heavy snow and power outages). If I had total control over the snow forecast yesterday I probably would've hedged closer to a foot rather than the 18. Like I mentioned with Will last evening, it seemed to evolve into more of a WAA snow, and it's hard to do more than a foot on pure WAA. We'll see how well the dry slot can fill in today. There are hints of moisture aloft moving back in, and cloud tops are cooling a little bit again, but I don't think we have another double digit period of snow.

On to the genny around 4:30 am. Woke up to 5.3" of sticky snow (~7:1).

Something broke with the scripts today and it nuked our actual forecast when the probabilities ran, so check it now for the actual current forecast. Not much different but a little beefier at the coast.

Nah. There was plenty of discussion, but overall we haven't really observed blizzards without it also being really cold, and that's just not in the forecast right now. Do I think there's a path to 20s and 1/4sm? Yes. But I'm not on the likely side at the moment.

That's the biggest difference I see between yesterday and today. There was a nice H7 low over SNE on yesterday's runs, but today it just kind of looks baggy or develops really late Thursday where it's almost over NH. In that sense it is almost purely WAA driven, which gives me more of a SWFE vibe of capping things at 10ish outside of the mountains.

Honestly I don't know much about the known biases, but I would hazard a guess that they'll be similar in nature to the HRRR (since they are both RAP based).

Yeah, when the reports started coming in of a possible microburst... But we did dig into the mesonets nearby and you could see the localized strong gusts. IIRC the inversion height was perfect for ranges like the Ossipees.

It's more that it is dry aloft in the mid levels. Wet bulb cooling the column is doing the bulk of the work there even with torchy surface temps. Surprised there haven't been a ton of AFDs crapping on the event because of warm ground. That was a great WTF event.

That's what we've found for the QPF side of the HREF. Picks out the max values well, but the areal extent is usually too large.

One thing I keep seeing on Bufkit forecast soundings is that the first 10-12 or so inches have deep saturation through the DGZ, but the next 6-10 the DGZ dries out. I would be pretty wary of that additional snow unless that profile changes significantly on these 12z runs.

LOL at the entire GYX CWA having 90% chance of 12" in 24 hrs from 00z Thu to 00z Fri.
