Would be a big storm for a lot of us!

Thank you! And that is still mid-storm. It is still snowing over the entire forum area at that hour (144).

I the cold is overdone and the model runs today are reacting to it

The gfs has been really really bad lately, right? I mean they all seem to suck now, but it’s been behind the pack iirc.

Euro has like 8+ inches in dc with the back edge still in Missouri. Yes please.

Even if total qpf is likely overdone, still a huge crippling storm

Hmm curious how many more hours it snows after the 144 hr model cut off

yeah, I feel like there would have been a secondary developing. jet is at least better aloft

Also on that 18Z surface/precip plot there's a lot more snow (and precip) still coming in at 144h it appears, compared to 150h at 12Z when it's mostly done and moving out (and mind you, 12Z Euro was still quite good).

Appreciate it Vortex The flaws of KBOS/Logan snow reports (at some point near a water treatment area? jutting out into the ocean?) and poor representation of the downtown area such as Boston Commons are very familiar to this board lol In this specific case, my own measurement of 5.5” in Coolidge Corner area and neighboring PNS reports are validating… even with some margin of error, the city probably has not yet broken 6”: 1 S Brighton 5.5 in 1015 AM 01/19 Public Logan AP 5.3 in 1041 AM 01/19 Official NWS Obs Chelsea 5.2 in 1043 AM 01/19 Trained Spotter Boston 6.5 SW 5.1 in 0700 AM 01/19 COCORAHS West Roxbury 5.0 in 0940 AM 01/19 Trained Spotter Chelsea 4.9 in 0848 AM 01/19 Trained Spotter Boston 3.1 SW 4.7 in 0700 AM 01/19 COCORAHS Logan AP 4.6 in 0703 AM 01/19 Official NWS Obs Chelsea 4.5 in 0800 AM 01/19 Trained Spotter West Roxbury 4.3 in 0815 AM 01/19 Amateur Radio Logan AP 3.4 in 1200 AM 01/19

Euro 18z looks same as the 12z

With more to come.

The 12z map is almost identical. I will grab one in a minute if someone else doesn't post it. Just remember, the 18z is still mid-storm when that map cuts off. Maybe take 50 miles off the north side - maybe.

That’s a better look on 18z euro at H5. Slower and trying to phase in some of that energy

Crush job for most all of WNC on 18z Euro. Some mixing issues as you head SW, but showing mid teens at the surface. This is one powerful storm.

Ouch with the EURO. Inch and a half of ice in the ATL area. Ooof.

If you like weenie ratios we’ve hit it already. Would be a nice storm.

Euro AI slunked south a tad at 18z. Still would be a good position for decent hit

We've lost almost 12 hours on it according to the Euro which only goes to make the forecast even further out in time

Not too mad at the Euro..looks like it'd def be over 6" if we made it past 144

Maps?

Not weather related...but worth noting that we are having one helluva solar storm right now. Sent from my SM-S908U using Tapatalk

Basically a repeat of 12z. Consistency and a big run which stops at 144.

Regardless of model, I have often found the "snow depth" field to better represent what you actually experience on the ground, with melting etc - almost like Kuchera+. But some like the GDPS don't use Kuchera for calculating snow depth (just 10:1). I'm not sure which models do/don't, or what site has snow depth derived with Kuchera.

Looks like it's been slowing down the past few runs?
