DAYS 1-5 (DECEMBER 17-21)
The WHW forecast area continues to be impacted by a winter storm, dumping a good amount of snow on much of the region, with a bit less to the southeast due to wetter snow, and even less on parts of the outer part of Cape Cod and over the Islands due to a change to rain there . The mix/rain areas will see a flip back to snow before the end of the precipitation, and areas that had rain and wetter snow will experience a quick freeze-up when the cold air returns during the midday and afternoon hours today. There is also a drier slot with less or even no snow falling in the Merrimack Valley through parts of central MA. These areas will see additional snowfall though as a heavier band to the north and west rotates back through while weakening. Eventually all of the snow will move out from west to east, ending with accumulation with most areas somewhere in the expected ranges. Tonight comes clearing and mid winter cold, despite it still being autumn. Colder than normal but dry weather will dominate Friday and Saturday. Sunday will see slight temperature moderation but also some cloudiness and the possibility of snow and rain showers as a weak low passes by. Following this should be weak high pressure with a dry, seasonable Monday.
TODAY: Overcast with snow except mix/rain South Coast and Cape Cod for a while before changing to snow by midday from west to east. Total snow accumulation: 1-2 inches lower portion of outer Cape Cod (Chatham) as well as Nantucket and Martha’s Vineyard, 2-4 inches upper portion of outer Cape Cod (Provincetown) as well as Mid Cape, 4-8 inches Cape Cod Canal area as well as South Shore up to about Plymouth and westward to the immediate coast of RI, and 8-14 inches elsewhere. Highs 25-32 north and west of Boston, 33-40 elsewhere with mildest Cape Cod and Islands in the morning, followed by falling temperatures midday and afternoon. Wind E to NE 15-25 MPH with gusts 35-45 MPH southeastern MA and southeastern RI, shifting to NW during the afternoon, and NE to NW 10-20 MPH with gusts 25-35 MPH elsewhere.
TONIGHT: Clearing. Blowing snow likely. Lows 10-18. Wind N to NW 10-20 MPH, higher gusts. Wind chill often below 10.
FRIDAY: Sun and passing clouds. Highs 27-34. Wind NW 10-20 MPH.
FRIDAY NIGHT: Clear. Lows 10-17. Wind NW under 10 MPH.
SATURDAY: Mostly sunny. Highs 30-37. Wind W 5-15 MPH.
SATURDAY NIGHT: Variably cloudy. Lows 20-27. Wind SW up to 10 MPH.
SUNDAY: Mostly cloudy. Chance of light snow/mix/rain Highs 33-40. Wind variable 5-15 MPH.
SUNDAY NIGHT: Mostly cloudy early, then clearing. Lows 21-28. Wind W 5-15 MPH.
MONDAY: Partly cloudy. Highs 35-42. Wind W 5-15 MPH.
DAYS 6-10 (DECEMBER 22-26)
Potential unsettled weather events December 22 and 24-25. Temperatures near to slightly above normal dropping to below normal at the end of the period.
DAYS 11-15 (DECEMBER 27-31)
One or two precipitation events possible during this period. Temperatures start cold then moderate.
Thanks TK !
Thanks TK
No measure yet but it sure is beautiful
https://imgur.com/a/zO8oW0f
Let’s guess. I say 11.8. 😉
That’s fun. I’ll measure before it’s added to. BRB
Before I go out. I’ll say 10.5. Next time I measure the pole above table.
that looks like 12.6 to me. 🙂
I’ll see if there are more guesses before I give amount.
11.8
Wait tk got that. 11.9
Band right over eastern mass is doing a number.
Looking out the window, I guestimate that we’re at 10 inches now (Perhaps a bit more) and counting. I’ll get outside later.
Based on my earlier measurement and the band we’ve been under must close to a foot.
Should we rename the Charlie Hole and call it the Retrac hole?
Dude it’s NFG out here and it’s not gonna get better. I’ll take the trophy from Charlie for now. Goddamit.
🙂 I feel for ya, but generally you do much better out that way. You can’t have it all. 🙂 🙂 🙂
I was snow blowing earlier and we have about a foot plus here in the Needham/Wellesley
Models did a nice job picking up on those two axis’s of heavy snow: one over eastern MA and the other across eastern NY and western MA with an area of lighter snow as in the middle.
Latest HRRR shows the snow lingering in Eastern MA until about 1AM tomorrow morning. Light to be sure, but snow in the air
with minor accumulations adding to the total.
Would not surprise me to see even Logan come in at 15 inches
on this one. We shall see. May possibly even be the largest pre-Christmas snow storm ever.
And Arod, I agree. I think the models did a very fine job with this one and I also think that the much maligned NAM performed exceedingly well. Remember, it was the first one to bring the SNOW so far North and to close off at 500 mb.
Perhaps a Kowabunga is in store???
It is getting close to that. 🙂 🙂 🙂
I am LIKING what I am now seeing!!!
🙂
On a different scale, kind of the reverse of what happened December 5th….
Radar shows no end to this band here in the Boston area for the time being. Well on our way to 15 inches plus in some areas.
Again, I can’t disagree. Looking that way.
The yellow echoes keep propagating and remain entrenched across Eastern MA.
https://radblast.wunderground.com/cgi-bin/radar/WUNIDS_map?num=40&type=N0R&mapx=400&mapy=240&brand=wui&delay=15&frame=0&scale=0.5304347826086957&transx=-35.81967213114751&transy=84.8360655737705&severe=0&smooth=0¢erx=364.1803278688525¢ery=324.8360655737705&station=BOX&rainsnow=0&lightning=1&noclutter=0&showlabels=1&showstorms=0&rand=26803493
it almost looks like we have some sort of convergence zone going on in the Boston area with NNE winds on the coast and N to NNE just inland. Combine this with the moist flow and the lift is producing these echoes. The ones to the South are likely synoptic.
sorry mean N to NNW just back from the coast.
Likely from that coastal front. Whatever is generating this snow machine, I’ll take it!
34 here now the precipitation seems to be picking up a tad . The snow here is very heavy cement like snow .
Just keeps going. Loving this. Keep it going.
Thanks, TK!
Hey, Good Morning, everyone!
Hi to the first-timers here at WHW, too!
7.5″ at 0800 looking at the snow gauge in Taunton.
There seems to be a little more on the deck. 9″?
32.4 degrees
We look like we’re going to get into that heavy band in the next half-hour coming up from Fall River.
Of course I wake up in the dry slot
Pretty much the same here in Amesbury. It’s snowing, but nothing to write home about.
Yellow echoes have gone poof, but still under dark green and still snowing hard. Big Donut hole “just” west of Worcester.
No sooner I said that and they are starting to appear again.
Not relenting here.
Quite frankly, there was no noticeable difference
in the snow intensity between the yellow echoes and the dark green echoes. 🙂
Let it SNOW! Let it SNOW! Let it SNOW!
White Christmas? Good chance!
Thank you, TK.
Thankfully, I was quite wrong when I thought this storm would be a near-miss.
I don’t believe I’ve ever experienced more snow before Christmas, at least not in one storm. That’s the amazing thing about New England. Every year there are surprises, in practically every season.
Just wrote an email to my daughter who’s in London telling her about the snow. As I said in my note, just a couple of months ago we had days in the 80s and high humidity. I had my oscillating fans going in late September/early October. Only a short time later, all the leaves are gone from the trees, vegetation is dormant, birds are barely active, and now we have a foot of snow and mid-winter cold.
New England, Gotta love it!
Thank You TK!
Well after 10 1/2 “ we’re getting dry slotted here. Maybe a little more on the back end like TK suggested to round me out to an even foot. Looks like Christmas now.!
Here’s your dry slot or Charlie Hole as we like to call it.
https://imgur.com/a/Rea0TDT
Feel like I have been under some sort of death band for the last 15 minutes.
Are you still in Newton, Longshot?
Moved to Swampscott. Where are you located Katie?
I’m right on the Wellesley/Newton line
Still really snowing hard in JP. Vis way down to around 1/4 mile.
Heading out to start the process around 9:30 and will get sole more measurements.
Good Morning , Still snowing hard in Essex . I would guess about a foot but the wind is just howling so it is really tough to tell with all the blowing and drifting .
Enjoy !!!
https://imgur.com/a/zO8oW0f
11.6. TK nice guess. Dr S honorable mention.
Well, where is the shot of the ruler in that snow???????
Would’ve have dropped the camera.
RIGGED! I’m calling the supreme court.
Haha!!
Those band north and here just keep pivoting.
I am seeing signs on radar of the snow beginning to wind down.
Snow has let up a tad here in JP.
However, still plenty of snow to the West. How much pivots through here? I dunno. We shall see.
Yeah some let up but still decent clip.
The snow hole is hungry and in the way OS. I feel like I’m watching a Carl Sagan documentary where he talks about light not even escaping g a black hole.
🙂 🙂
11.4 here in Billerica Ma with light snow. The heavier stuff is now down near 128 and seems to be staying to the south and east of me.
Quite the winter wonderland out there.
I just measured 11 inches. Even though I am getting lighter snow I think I could get a foot of snow out of this.
12Z NAM has the snow quitting in Boston at 4 AM tomorrow.
Eric was talking about this the other day and even that this would help pile up the snow totals.
My opinion 4am is kind of pushing it old salty
Boston will need 12.7 inches to get into the top 5 for biggest snowfalls prior to Christmas.
Piece of cake. May be there already.
My friend said that NYC changed to heavy sleet around 11 and is now back to snow.
She is hearing 10” in Central Park.
Last report NYC came in with 6.5 inches of snow. They had only 4.8 inches all of last winter. Binghamton, NY I saw with 41 inches of snow. Some of the short range models nailed that area and said that area would be hit hard.
Do you where they measure JJ?
Central Ma Snow Hole is expanding!!!!
https://imgur.com/a/jz5ZVZK
Should have taken the snow display off. This site has been messed up all year on the snow depiction. 🙂 🙂 🙂
Lol. And I’m dead center in there. Think I’ll go outside to see if I can see into space
All Hail To The Farmers’ Almanac for getting this right for predicting a major east coast storm for middle of December. I know I will not hear the end of this from people I know act like it’s their bible. I say lucky guess. Now let’s see if they get right the 12-24 inches of snow for second week of February.
Trying to get my son home safely from his first semester of college today. He is traveling from Dutchess County, NY to Southern NH. He will be traveling 290 to 495.
When is a good time to have him start?
Based on what I can see on TV radar it looks to me like leaving NY between 12:00 and 1:00 he should be safe.
Thanks TK.
Had just over 4″ of snow down here with this event before a change to sleet then rain. Most of that 4″ came in about 2 hours, and the rates were briefly quite extreme before the changeover. Largest snow event I have seen since March 2018. And a fairly well cooperative forecast here 🙂
Been very busy with work so kind of lost track of the happenings in SNE. Looks like a solid snowstorm. However, totals there will pale in comparison to the potentially historic numbers coming in out of the southern tier of New York. Amounts of 35 to 45″ in the Binghamton, NY area, and I’d imagine we’ll see a few 50″ totals trickle in by the time it ends. As usual, going to be a lot of lessons to take from this one.
WxWatcher down your way Philly ended that streak of less than an inch of snow for 651 days coming in with 6.3 inches. Last year they only had 0.3 for the entire winter.
Boston 9.6 as of now
Where did they measure that? Out at Boston Buoy. Must have been MUCH wetter snow at Logan than here. We are clearly over a foot here in JP. 🙂
Ha yes way over a food. Heading out now.
Reporter in either common or Gardens just said 10 there but I don’t know if it was a guess or actual measurement. Was watching 7
As usual way low for Logan. Useless location to measure.
Thanks TK. Just reported 11.5″ to the NWS here in Coventry and still snowing lightly. The models certainly did nail the snow hole in this area as retrac mentioned. A bit disappointed but still a nice storm and still a bit more to come.
The totals coming in from Upstate NY are astronomical. My mother in Amsterdam, NY, who had been expecting 6-10″, woke up to 2 feet of snow and its still snowing heavily under that band. Some 30″ reports from Albany and Saratoga County as well. Will be a top 10 storm there.
And then there is Binghamton which sat under that intense band for hours overnight. 41″ including 18.5″ in 3 hours and 15 minutes. And with no lake effect influence. Incredible.
Many of the short range models, along with their projected Kuchera snow totals, nailed this. The Canadian model suite in particular, which had been fartherst north all along.
JR just mentioned how well the models did with that hole also. Pretty good.
Agree Mark. Models on balance and from an overall perspective were really solid. If anything they might have been underdone on QPF for the NE in Aggregate I don’t know. Bernie is a wicked spaz but props to his overall forecast that far in advance.

I saw something earlier where in just this one storm Binghamton picked up half of what they get for an entire winter season.

Click on the individual pictures in that Twitter link to blow up and expand those photos. And keep in mind they got another 10″ on top of that after the pictures were taken!!
Vicki do answer your question from earlier for NYC the official records are kept at Central Park.
Hmmmm. Not sure where friend heard 10. She did say she was just hearing it and not official. Thanks.
Mark looking at those photos it brings back memories of the Blizzard of 2013 here in CT. A solid snowstorm here in CT which looks like a general 8-16 inches.
It is a family affair. Daughter is out there also. Oldest grand just came in

Thanks all. Sure made me smile too. Seven year old managed to clean my entire car. I was surprised he could reach the roof.
Oh my gosh the little guy is so cute it hurts!!
Thank you for sharing this Vicki!
Thank you. That is the youngest Rilyn Mac. Evan….doing my car in the pictures ….somehow managed to do his dads truck. And I didn’t think he’d reach the roof of mine. One determined young man.

Amazing. Thanks, Tom. Will share with my weather loving granddaughter.

Just lighter green echoes here in light snow.
Winding down the accumulation now most areas..
The report ranges for the WHW forecast area are about 7.5 to about 14 inches with less to the SE as was expected. No doubt a few of those numbers will increase as they were reported before the accumulation had finished.
Boo!
I’m actually quite pleased with it.
Boo as in the snow is winding down. Your forecast was excellent and on point per usual.
Like here as it’s startling to pickup
Woke up hoping it would be a little colder in the boundary layer here, but to no avail.
Still 36F. See Buoy is at 050 and dropped a 1F.
In lighter precip, its thick drizzle, in heavier precip, its a majority snow. Nothing has really melted from overnight.
Our street has been plowed well, what remains is a layer of slush and water.
11 inches and now the sun is out where I am. The snow thankfully was easy to shovel.
Pretty good, must look nice !
Tom it looks nice but the wind is blowing it around. Another thing for those going to shovel bundle up as the wind chills at least where I am are in the teens.
A moderate ban is over us now here on the south shore .
Tom you in on it .
Too mild this coast to the ocean. I am seeing a mix of rain and wet snow. Need a temp drop of a 1F or 2F 🙂 🙂
coast – close
Vicki the 10 inches you heard friend heard for NYC is correct.. I am looking at the latest snowfall report from Central Park and it is showing 10 inches. With this storm Philly and NYC got more snow than they did all of last winter. Philly had 0.3 last winter they have 6.3 so far this winter and NYC had 4.8 last winter they have 10 inches so far this winter.
Nice. Thanks. I would have been surprised as she is a stickler for detail.
10:30 am
Boston Harbor buoy wind now at 030, temp dropped to 34F from 36F a few hours ago.
I hope to get back to complete snow in the next hour and top this cement with hopefully 1-3 or 2-4 inches of snow by this evening.
Harvey saying an additional 3-5 inches here
Yup, the precip could carry on a while down here due to a slight onshore component later today, so there are many hours of slow accumulation to go after this steadier batch.
I’m good with that
Snow is picking up a bit here.
Keeping an eye and see if Boston cracks the top 5 on this list for biggest snowfalls prior to Christmas. Eric Fisher posted this list the other day.
1. 16.2 back on 12/7/03
2. 15.4 back on 12/22/75
3. 13.0 back on 12/13/60
4. 12.9 back on 12/6/81
5. 12.5 back on 12/20/08
I remember #2 and #4.
For #3 I was an infant. 🙂
Based on where they measure I almost doubt it lol
Boston Harbor Buoy shows ocean running at +2 ft surge.
If that holds onto a 11.3 ft tide, that would be a 13.3 ft tide at 12:52pm, looking to verify minor coastal flooding.
Its those tide and surge combined 14 ft and higher tides that cause the biggest problem.
That absolute bomb (963mb) 3 or 4 January´s ago had a 10.4 ft tide with a 4ft storm surge for a 14.4 ft level along with much bigger waves. The coastal flooding was bad enough in Marshfield they actually did a few water rescues.
THE BOMB CYCLONE is what the media was calling that storm you mentioned in January 2018.
The models yesterday did an excellent job of forecasting that dry hole that developed over SE NH this morning. Those “futurecast” radars usually don’t even come close.
It’s really cranking here now in pembroke & the wind is definitely picking up
The wind is screaming
Yes, very noticeable increase here too.
Unofficial Totals. (Watch the time stamp.)
https://forecast.weather.gov/product.php?site=NWS&product=PNS&issuedby=BOX
Thanks Longshot. Just a hair under 14 inches here in Westwood with light snow falling.
The accumulating snow has stopped here in Billerica about a half hour ago, still some small flakes flying but nothing accumulating. A ever so light wind has formed and is starting to blow the snow on the ground a bit. Measured 12.2 inches here in Billerica. Wouldn’t be somethin if that heavier snow up in NY and Vermont was further south. NY, VT and NH I totally busted on.
Looking down the pipe line
Tk alluded to these possible periods of time but
Monday night/Tuesday next week weak polar jet system if I am not mistaken looks to dive down from the great lakes
With another larger system being possible around X-Mas
I am not to impressed with that system as most of the signals I am seeing is rather marginal in terms of temperature.
Just measured 7” in the desert. Wind might have gotten to my board a little but what’s the diff. out in the Charlie Hole.
🙁
That sucks!
About 10 inches here in Hingham. To Mark: a lot of it was wet and heavy. Leaf blower method wouldn’t work. You owe me a new back lol
LOL, forgot you were down there or I wouldn’t have recommended that. Take some advil!
Finally ….. visibility just lowered and we are back to snow.
Blizzard like conditions at times . I just drove around my neighborhood & center of town to observe & the roads are a mess .
same here 🙂 🙂
We got 10ish inches in New Haven area. Maybe a bit under.
A decent band just set up over us. I’m assuming it won’t stick around too much longer, but nice to see some in the daylight
Ok – you got me. Even I, snow curmudgeon personified – have to admit it. This one is beautiful – a flipping winter wonderland and I am LOVING it! Even more so reading the joy here on WHW 🙂
Smiling here. It is awesome, mama!
44″ of snow reported in Ludlow VT (the town at the base of Okemo). Widespread 30-40″+ reported in southern VT. Even Killington up in central VT pulled out 16″
https://forecast.weather.gov/product.php?site=NWS&product=PNS&issuedby=BTV
Wow! Incredible! The Southern VT ski areas received a bonanza!
More locally, I wonder how Mt. Wachusett did?
After the last few seasons, happy to see southern and central ? ski areas get this. Hopefully, they can do some social distance business in the new few months.
Here’s a shot from Okemo…

Parking lots are currently inaccessible due to the amount of snow.
wow !!
I love Okemo. Skiied there once with the Mrs. a long time ago. I remember she wiped out once and scraped 1/2 the snow off the trial with a beautiful rooster tail… She got up, dusted herself off and continued down the trail. What a trooper!
It was so long ago, they still had a pomer lift. That was a struggle to the top of the mountain.
Here is what they look like:

30″ there.
Visibility 1/2 miles. Horizontal wind whipped snow.
The yard looks like the beach on a very windy day.
The cement isn´t moving, but the new snow atop it looks like sand being blown around on a windy day at the beach.
I’ll take the 9-10 inches we got up in Amesbury. It’s really pretty by the Merrimack. Since we moved here 2 years ago from North Reading, I’ve noticed that we get a little less snow up here than we did in NR. Am I imagining this?
There is the magical snow hole that forms in the Merrimack Valley due to a snow shadow effect or we end up mixing

They sat under that death band for a good long while, not to say the snow on either side of the band, wasn’t intense enough. 🙂
A long a training line of thunderstorms in the summer. Wow!
Like a training…
That couldn´t have worked out any better for Binghamton.
Photos from Maine NY where 45″ of snow was reported:

And to think this is a whole foot of snow more than the 32″ I got in Nemo. Wouldn’t even know where to begin clearing this.
Insane
Until and unless any ocean bands set up later, then
this thing is just about a wrap here.
I am thinking somewhere between 12-14 inches. I “hope” to get a
measurement later. Too many people out on the street right now and I don’t see a mask on any of them!_@#(!@)(&#)(!&@#
I’m almost 74 and I ain’t taking any chances!!!
Crap!!!! that sounds awfully old. I do NOT feel that old, that’s for sure and inside I still feel like a teenager.
Temp down to 24.
I’d say this storm delivered. Not a Kowabunga storm in my area.
Certainly In NY and VT it was worth of a double/triple Kowabunga.
I don´t know if you saw a post of mine towards the end of the last blog Mark, but great job on this storm !! You really questioned the GFS and also focused a lot on that heavy band that clobbered Binghamton, Albany and southern VT and it sure as heck verified. 🙂
Thanks Tom! Only wish it didn’t shift THAT far north.
Just came in and boy that added up.
Measured 15.7, saw a 13 inch total at 8 AM from JP so I feel like I didn’t screw this measurement up. Checked multiple places as protected as possible.
Worcester coming in at 12.2, Logan had to easily eclipse that.
Logan sucks, so who knows what they got.
Temp down to 28
Great job everyone! The storm was really nice and a lot of fun with the kids.
What’s next? Anything on the horizon?
There is an off shore storm trying to develop early next week that needs to be watched and unfortunately the models are all showing a system passing to our west around Christmas Eve/Day that would produce a brief warm up and band of rain showers moving through. Still a ways off.
12.9 for Logan is respectable. Just out for session two and must be close to 17 this point. Didn’t do a measurement, but my neighboor did and he came in at 17.6.
Just came in from clean up. Bright sun through partly cloudy skies at 1:00pm here.
We got about 8″ here. The valley area towns just east of the Connecticut River in Hampshire County got a general 7-9″
Overall forecast was pretty good. But holy expletive, New York State !
I am a model skeptic as you know, but there was some good output for this storm.
The faster, further east progression of the Monday system I think will prove to be one of the most impactful reasons for the actual outcomes of today’s event.
Thanks JMA for your insight.
Indeed, thanks JMA!
Just talked to my mother in Amsterdam, NY and she received 30″. She was stunned when she woke up this morning. They only had about an inch on the ground at 11PM and by 6AM there was about 2 feet. Basically snowed 3″/hour there for 7 hours and then continued to snow heavily 1-2″ per hour most of the morning as the stationary band slowly decayed.
Wish I was up there for this one!
What did the locals forecast?
It started 6-10″ and by last night in the midst of the storm, the NWS upped it to 10-20″. Still not nearly enough.
Early signals that Christmas Day might be cold to very cold or have falling temps as the day progresses.
The signals for 12/22 are promising for preventing a major modification of temps, especially for the interior. Getting some wet snow out of that would be an additional extra.
That won’t help with outside distancing.
Thanks guys. Still snowing here.
According to Eric 12. 9 for Boston which is tied for fourth for biggest snowfall prior to Christmas. I think they should be able to 0.1 to be in fourth alone.
I also believe you could add Boston to the list of NYC and Philly where they now have more snow than they did all of last winter.
I just checked my spreadsheet
I had 20.9 and Logan had 15.8 last year, so you are 100% correct.
Thank you for looking that up JpDave.

Euro surface feature with that not so hot at the moment, but we
have 5 days or so. 🙂

Still snowing in Swampscott though t the tail end.
Mark, thanks for sharing the tremendous snow totals (and pictures) from your home state (I know you live in Connecticut now, but are from NY). Your Mom must be thrilled to have 30 inches of snow. I know I’d be.
Having a healthy snow pack in the Boston area, but also an even healthier snow pack west of us, and of course to our north, will contribute to some radiational cooling but may also prevent major warm-ups from any west/southwesterly that may develop over the coming week.
You are welcome! I enjoyed the snow here but am envious that I was not up there for this one. I’ll get to see what is left though when I am up there during the holiday week.
So, If I am not mistaken the GFS Par (run only at 00z did way better than the operational GFS with this system and the last one as well if I am not mistaken.
Certainly with this one. 🙂
Still snowing here with windy conditions. It’s going to be a stormy night here .
9.2 inches was recorded well over an hour ago so I think with snow still falling & more to come I think I’ll hit 12” easily . It’s light now but definitely sticking .
Not sure how this ended up above.
12.9 for Logan is respectable. Just out for session two and must be close to 17 this point. Didn’t do a measurement, but my neighboor did and he came in at 17.6
TWC named this storm “Gail”.
Oh brother. 😉
Too bad Gail didn’t really produce any gales 😛
Seems to be winding down Tk trying to get official measurements
The 17 inch has to be too much. Must have some blowing and drifting involved. I am guessing more like 15 is a realistic number.
Logan may be up to 13.5 inches, if I interpreted correctly what I saw on ch 5 a few minutes ago.
Makes sense. That band sat here for hours early this morning.
I can’t measure accurately with the blowing. I know we absolutely had an accurate 11.6 this am. It seems we had one more inch this pm. So conservatively 12.5
13.2 inches for Logan.
So far they are at 24th place for snowiest December on record. Long way to go to reach #1. 😉 However, they will come in above normal snowfall for the month, no matter what happens the rest of the month.
My final was 14.0 here. Viewing the reports, the vast majority in the 8-14 forecast area came in between 8 & 14 and there were a few under 8 and a few over 14. I’ll take it, from a forecasting standpoint. Just finished a 2-hour shoveling job and now it’s time to shower & have hot tea & then dinner & watch some holiday specials tonight. 🙂
Not bad at all. I think you can pat yourself on the back for this one. Well done!
Looks like your December winter forecast verification is already pretty much in the bag! Here’s to hoping that accuracy plummets come January 1st (sorry 🙂 )
Looking at what Boston recorded and Eric’s tweet for biggest snowfalls prior to Christmas for Boston it now ranks number 3.
Having a storm produce over 40″ of snow is rare enough. Have it produce 40″ or more across 4 DIFFERENT STATES is unheard of!

Up to *7* inch per hour #snow rate in New Hampshire.
Anecdotally…in over 20 years watching winter storms, that ties the highest snow rate I’ve seen in the U.S. outside of lake-effect snowbelts or pure orographic events.

Yowza. I cannot tell where in NH this is. I’m sure the location is staring me in the face though
Ossipee

It’s still snowing outside but I’m such a snow junkie I couldn’t help but peek at guidance in search of our next storm.
Met friends: check out these 120hr 500mb forecasts…
Non-met friends: we *might* have another system to think about early next week. Stay tuned.

As others have alluded to, this big E Asia positive Mtn Torque event (+EAMT) w/ a big Siberian high descending into China late in week 2 signals another big N Pac Jet extension in week 3 >> another bout of strong +PNA as we enter early Jan?
As a SE US snow weenie, I sure hope so
https://twitter.com/webberweather/status/1339601777541349377?s=20
I would not mind one more snowstorm just prior to Christmas early next week.
I’m bummed this is over I hope I get one more event at home before I go back on 1/12
I could catch up on sleep tonight and then starting looking at the early next week potential tomorrow.
WHW Poll Question–will this be the largest region wide snowfall of the season?
Very possibly, but we have a looooong way to go. Maybe one will rival it in March on the way to verifying the risky part of my winter forecast. 😉
It may be hard to get another storm this season that drops double digit snows over such a wide area of the Northeast but I think we will see another storm or two this season that drops higher snow totals than this over at least parts of SNE.
Good question
Based on all the long range forecasts for this winter I would say yes. I hope I am wrong. I am just happy I got one storm to produce a foot of snow.
18z GFS intriguing for the early week ocean storm. Gets SE MA briefly into the outer precip shield as rain/snow:

Meant to post this hour for the CMC:
https://www.tropicaltidbits.com/analysis/models/?model=gem®ion=us&pkg=mslp_pcpn_frzn&runtime=2020121712&fh=108
Looking interesting, BUT, the main action seems to occur too late and too far off shore. There is time. Let’s give it a good watch, perhaps we can kick it into gear.
This one would be deepening, that’s for sure and likely capable of dynamic cooling if we can get into any of the heavier precipitation.
I was finally able to get outside without anyone around.
Sadly, I didn’t get out there until basically 8 hours after any meaningful snow ended. Thus 8 hours for compaction, sublimation in the cold dry air and snow blowing around.
Still managed to measure 12 inches on the level. I assume we
got 13-15 inches, so let’s call it an even 14. 🙂
Tom, You snowing down your way? I see some light ocean effect snows backing in. 🙂

John, Look out the window. I think you have started snowing again. 🙂
Ok I’ll go look
🙂 🙂 That a boy. 🙂 🙂
Ocean snow bands from about Cohasset all the way down to the Cape Cod Canal are expanding.
C’mon, make it up to Boston. Would love to see a few more inches on top of this. 🙂 🙂 🙂
Just looked seems light . Is it sticking around
HRRR has it around through 9 AM. 🙂
So it’s going all night ?? I’ll keep an eye on it during commercial but if definitely was not coming down hard . Driveway was plowed 3 times with shoveling ( heavy stuff )
Oh, I didn’t pretend that it was anything but light, just that it was there. HRRR has about 2 1/2 inches falling over night.
https://m1.pivotalweather.com/maps/models/hrrr/2020121723/018/snku_acc.us_ne.png
Wow that’s cool I’m home for 3 more weeks so all good here . I want to see another where the plows come out .
It’s also the HRRR, so take that under advisement.
NAM has about 1 inch. 🙂
Ok thanks for the heads up old salty . What do you think they got at work
13 inches
I am willing it away.
Are you more on the Weymouth side of Hingham or closer to Hull/Cohasset?
If closer to Hull/Cohasset, then you may have a few flakes already. 🙂
Yeah close to hull. Ugh.
And???
One more shot from Endicott, NY….

NsfwWx tweeted out the setup for early next week. As JpDave said let’s give it a good watch.
https://twitter.com/NsfwWx/status/1339716845243396096
My daughter’s team was registered to play in a softball tournament at the Adirondack Dome in Queensbury NY (just south of Lake George) in mid February. Just got word that is in jeopardy as the roof of the dome just collapsed under the weight of the snow. Queensbury reported 33″.
Wow ! !
Wow! So sorry to hear that. Is there another venue? Not likely to be repaired in time.
Not sure if the coach will try to sign them up somewhere else or not. There are not a lot of options out there right now with COVID and being it’s winter. They are scheduled for another dome tournament in Danbury in March. These are really just practice for the regular tournament season with starts in May and is basically every weekend until early August. I’ll be softballed out in no time so I won’t be heartbroken if that weekend frees up and we can make a ski day out of it instead!
Wow! When you were talking about roof collapses it brings back memories of what we went through in 2011 when we saw a lot of roof collapses during that snow blitz stretch we had.
JJ rhe roof collapsed at the indoor where my daughter has her horse years before. When she was riding there, the supports bowed during some of the early 1990s storms. We were assured could not possibly collapse. Fortunately no one was in it when it did
With 13.1 inches 4th largest December snowfall on record for Boston according to a tweet I just read from Eric.
It’s picking up old salty with new accumulation
Same here, light snow falling.
We need to make up for those 3-4 hrs of mix with no accumulation. 🙂 🙂 🙂
After having a wind at 360 this evening, the harbor buoy now has a wind of 020, so, that´s probably why the ocean effect is increasing a bit.
Temp is up slightly at the buoy too, to 33F.
Can get strange temps along the most immediate coastline on south shore when the ocean is 47F. So, who knows, this might go back to mix rain/snow here but may give SSK a new 1-2 overnight.
It’s 28 here now Tom
yes, your good to stay below freezing all night. 🙂
A little lighter now with the snow
18z Euro with a nice look at hour 90 as we get into early next week. I’ll be interested to see the next couple Euro runs show. 12z wasn’t far from producing something on the 21st/22nd either.

So the long-eyed period of December 16-17 ended up producing quite the event for us, even more remarkable than any of us could have imagined – not for most of us, just a nice December snowstorm (mess storm for some), but that snow band to our north and west – I know I sound like a busted record but just fascinating.
So now our attention turns to the upcoming 3 “windows of opportunity”, December 20, December 22, & Christmas Eve / Christmas Day. At this point I am most intrigued by the middle one. Keeping in mind the models inability to really peg stuff more than a couple days out, if that, the pattern leading up to it is one that makes me take notice. While I’m pretty sure our Sunday “event” won’t be much of an event, probably just light snow & rain (depending on location), the threat for next Tuesday, assuming that timing holds, has quite a bit of potential in the atmosphere to work with. This eventual play-out of this will probably have an impact on the third possible event, which is probably not being properly handled by medium range guidance at this time. So, to summarize, there is a whole lot to keep an eye on through Christmas….
Yes!!!Thank you! I’m excited for more snow.
I haven’t been looking forward to snowstorms the last couple of winters but with everything going on in this country these storms have been taking my mind off of things! Keep it up!
Bring it on
You’re really into snow this year.
Boston snowfall to date = 17.7”
Boston snowfall 2019-20 = 15.8”
Eric is eyeing Christmas Eve. According to him if the storm goes west (rain), if to our south (snow/mix). Either way, next week will be somewhat active.
This morning, Ch. 7 has early next week very quiet then late rain showers Christmas Eve.
I’m not so sure I agree with “very quiet”. We may be eyeing the evolution of a pretty potent ocean storm “too close for comfort” Monday night & Tuesday.
Eric was very vague about that because he knows that the current scenario on guidance may not even be close to correct.
New weather post…
