They are. The GFS was legit forecasting real snow and ended up wrong. But even after it trended north, the “snow depth change” was looking off compared to the usual clown map of just snowfall.

Sleet and some crappy flakes mixing in with this next batch....temp down to 24.8F.

Yeah the models have gotten a lot better at identifying the marginal boundary layers....but at 3+ days out, it obviously can still be off. The March 7-8, 2013 storm was like that....that's the one where he just got firehosed from the east and slammed 12-24" in mostly a 15-18 hour span (but we were spitting snow showers for 24 hours before that)....model guidance had initially kept trying to warm the BL, though a couple model runs were showing around -1C at 950mb, and then they kept cooling until it was like -5C....obviously that is an extreme example....it can snow at -1C. But the forecasts were very conservative at first....showing very little inside 495 and even only a sloppy 3-6/4-8 for ORH hills.

18z NAM has a nice burst for RI and SE MA overnight....like 1-2 inches.

They don't have the individual member ptype maps out yet, but the mean snowfall has zero inside of 495 or so with a few inches in ORH county and a bit more into interior S NH and ME, so that tells me even the "good" tracks are mostly rain outside of those areas. The caveat though is of course the modeled BL temps and snow algorithms too....sometimes in those blue bombs, models won't pick up on the isothermal nature of the atmosphere below 3000 feet and will try to over-warm the BL.

Yeah it was really cool...like there were legit dendrites in there even though pellets were still ripping from above.

EPS has a lot of good-looking members....but most of these are rain outside of ORH county into CNE/NNE. The low levels are trash.

Driveway is going to be a disaster....just gonna have to wait for the Tip warm fanny days next week. Maybe i can push some of this off later, but it's already frozen pretty solid.

Some people take "Above average" to mean a blowtorch with no snow chances....but this isn't that type of pattern. But I agree, people should really look at model guidance for next week...it's not cold. It's not a torch either, but in February if you have a little sun with that atmospheric profile, it's easy to have highs cracking 40F. Might be some high diurnal ranges too...where its pretty cold in the morning...esp the rad pits that have snow cover. It does look like we could get an arctic shot or two beyond that though.

Legit flakes here underneath the warm layer....we're still ripping pellets but this is what else is falling:

We have a lot of crappy flakes right now...like it almost looks like the predominate precip type now. Vis is def down to less than a mile as my reference ridge line about 0.8 miles away is obscured now. You might get some OES enhancement as the flow at 900-925 turns NE/NNE after 21z.

I feel like the RAP is too warm in that layer...NAM was WAYYYY colder and the NAM is usually pretty good aloft...the RAP had a bunch of us barely below frezing at 925 while we were all slamming heavy pellets at 32F earlier with a massive fat warm layer....which doesn't make any sense. It would require a very cold layer in there to get pellets.

This is what I always envisioned when TWC had "wintry mix" as the forecast back when I was a kid. It usually didn't verify like this (instead it was like straight ZR or a defined transition from snow to sleet to ZR), but this is definitely that type of day where truly a mix...we've had ZR/IP and SN- all throughout this morning and often at the same time.

Perfect for skiing....get that dense base down and then fluff the top

I don't think it looks that cold after this weekend...I wouldn't be surprised if we have plenty of mildly above normal days, but it's also not a no-threat pattern for snow through mid-month. The atmosphere will support snow with a decent track...it's plenty cold for that. We might get a deeper arctic shot toward mid-month as the western ridge amplifies.

We're getting absolutely ripped with pellets right now and a LOT of pixie dust....there's def crappy flakes mixed in now due to that very cold layer in the 925-950 region.

Ukie was pretty good for deep interior north of the pike...like N ORH county into NH and Maine.

Almost like there is yet another pulse up around Essex county....I noticed earlier they kind of rotted in the 29F range and then quickly went down to the 26-27F range the past hour or so. We're now getting into that 29-30F range here....everything is rapidly icing up solid, not just elevated or snow covered surfaces anymore. It'll become really nasty when it falls another pulse down into the mid 20s.

Tickled below 31F here now...any standing water is quickly freezing up....being covered pellets also expedites the refreeze.

GGEM has a little snow for interior....but doesn't pop it quickly enough....hammers DE Maine though.

Yeah likely an interior special if it gets close enough....though if it can deepen fast enough, it could prob collapse the 900-05-mb layer back toward the coast, but that is a longshot.

HRRR has some, though not quite as enthusiastic. RAP has a nice burst too, though mostly for RI/SE MA....but we do get a little flip to snow around 00z here prior to that second burst coming in for SE MA?RI on the RAP.

Yeah it's absolutely ripping down the coast now....I see 29F in Hull, MA...lol. Coldest spot at that latitude in MA east of the west slope of the Berks.

There are prob going to be some crappy flakes mixed in soon because the cold layer gets to like -9C or -10C which supports snow growth even though its torching above that layer.

Looks like the 30F isotherm is roughly from Chelmsford to Burlington to Winchester to Revere....it goes further south the closer to the coast you are. The Euro actually ended up pretty darned good with rotting us near 31-32F for several hours before the 20s get here. But we're pounding sleet anyway despite being near freezing....since it's frigid just off the deck at 925-950.
