Synoptically, this is pretty classic for SNE Miller B. Ohio Valley shortwave running into a blocked 50/50 low

The last time we had a threat inside of 6 days that was this good-looking was probably last winter. 12/16 did look pretty good but not sure it ever really got inside of 6 days....the last great runs we saw on that one were during the 12/10 GTG when the Euro tried to reincarnate Dec '92....but then it turned crappier almost immediately after those runs. 12/23 looked good until about D7. This is prob the closest we've been all winter to a modeled warning snow event.

EPS definitely not holding back

This is like that stretch in 1956....one after the other every 2-3 days...just don't tell Ray.

Ukie is on board for 2/28....redevelops it quick enough similar to GGEM.

LOL, it actually does but it's too phased and taints us.

Lets try and phase a piece of that PV lobe into the D9 system on GGEM ala March 4-6, 2001.

Yeah it redevelops quick enough and moves almost due east south of SNE

Good step in Euro direction that run....hopefully we keep trending that sucker.

GFS is already trending at 108....not sure if this solution will be eye candy yet, but regardless of what the final solution is, you can see the block holding tougher.

Almost every single snow "Event" I've had has been at these temps. It's amazing....even when we have like -5C 925 temps, we cannot buy a good sfc PPT prior to the storm....we get one in the middle of this storm, but that doesn't do us any good on the front end, lol. Only real exception was the 12/11 clipper-esque system where we had temps in the mid/upper 20s. We did drop to like 31F in the middle of the CCB on the 1/23 "happy ending" storm, but obviously a significant part of that one too was at 33-34.

Icon gone wild....but the reason ti did was because of the block. It was more Euro-esque and really held those lower heights to our northeast stout.

Did have a nice 3-4 hour burst here....that would be nice to grab a few. I'm skepitcal though until there's more evidence we get some good rates.

Yeah a lot of these 12z runs so far are pretty weak sauce with the precip rates this evening....I'm envisioning a lot of 1 mile vis light snow that accumulates slowly on the grass with maybe a heavier burst in the final hour before it flips. I was hoping for 3-4" but I haven't really strayed from my personal thoughts of an inch or so.

Antecedent airmass is actually decent out ahead of the storm....it's just a question of the block being good enough to force redevelopment soon enough to hold in that airmass....if not, then we erode it and get a pseudo-cutter, but on the Euro, it redevelops and we're good.

Yeah well the HRRR is usually....

3k is more aggressive with the tuck than 12k. Brings BOS below freezing by midday Thursday

It's further southwest but less east....it's trying to maintain a CF which is also what the Euro was doing until late Thu afternoon....though the NAM maintains the CF into Thu evening.

It really accelerates Thursday morning.

Thing is, we haven't seen this depiction all winter...it's been like 100 miles north of this with the best over Canada border region usually. So even if this is too far south, it's going to bode well for a large part of NNE/CNE.

HRRR gets teens into metrowest now, lol

12z HRRR looks a little more thumpy here this evening. Has 4-5” on the 10 to 1 maps but even half of that would be nice. Im assuming the first couple tenths are basically going to be wasted on a slushy coating because the sfc is pretty warm to start.

I’m not planning on much snow here. But if we get 3 or 4 inches I’ll be pleasantly surprised. The most interesting part of the event here is prob the temp crash during Thursday.

EPS continues to get snowier for us. Man, just have one of these threats go right.

06z euro looks like it ticked slightly colder than 00z. Gonna be close here. I could see half an inch before pellets or 4-5”.
