DAYS 1-5 (JANUARY 24-28)
A bubble of high pressure will bring fair and cold weather to our area today. A small low pressure area cutting north of the region brings a warm front toward us tonight and through the area early Tuesday with some light snow except mix/rain South Coast, followed by a brief interlude of milder air during the day Tuesday. After that, the low’s cold front will swing through and return cold but dry weather to us for Wednesday and Thursday ahead of the next disturbance which returns clouds and the chance of some snow showers by Friday…
TODAY: Sun and patchy clouds. Highs 26-33. Wind NW 5-15 MPH.
TONIGHT: Clouds increase. Periods of light snow late evening and overnight with accumulations of generally under 1 inch but up to 1 inch possible, Lows 18-25 evening, rising slightly overnight. Wind S to SW up to 10 MPH.
TUESDAY: Mostly cloudy morning with lingering snow showers except mix/rain showers South Coast. Partly sunny afternoon. Highs 35-42. Wind SW 5-15 MPH.
TUESDAY NIGHT: Partly cloudy evening. Clearing overnight. Lows 13-20. Wind shifting to NW 5-15 MPH.
WEDNESDAY: Mostly sunny. Highs 20-27. Wind NW 10-20 MPH, higher gusts.
WEDNESDAY NIGHT: Clear. Lows 0-8 except 8-15 Cape Cod. Wind NW 5-15 MPH. Wind chill below 0.
THURSDAY: Mostly sunny. Highs 24-31. Wind N up to 10 MPH.
THURSDAY NIGHT: Partly cloudy. Lows 12-19. Wind N under 10 MPH.
FRIDAY: Mostly cloudy. Chance of snow showers. Highs 23-30. Wind variable up to 10 MPH.
DAYS 6-10 (JANUARY 29 – FEBRUARY 2)
Watching the January 29-30 weekend for a potential winter storm threat. Model guidance remains variable and inconsistent, as is usually the case. However the pattern supports at least something nearby, if not directly impacting the region, favoring the first half of the weekend, followed by a shot of windy/cold weather. Cold end to January then perhaps a slight moderation and a little unsettled weather to start off February.
DAYS 11-15 (FEBRUARY 3-7)
Transition to a milder pattern gets underway but may involve some additional unsettled weather between milder air trying to move up from the south and still cold air to the north.

I think you NAILED the forecast. Thank you.
I see you are not biting on anything just yet. I understand, but clearly it is getting more interesting. Will be fun to watch, no matter what actually happens.
Question. can this pattern potentially support a monster of a storm?
When the models continue to signal a powerful storm run after run in the same general area, then usually, you do get a powerful storm. There’s something there that they are all latching onto. The devil is in the details. And that’s still unknowable this far out.
If I’m tracing it properly on the GFS, the upper-level energy responsible for the system will move inland from the Gulf of Alaska on Wednesday. That’s when we’ll start to have a bit more clarity hopefully.
Thank you SAK. much appreciated.
should be an interesting week.
WE all know VERY WELL that models are unpredictable. I absolutely agree with you though. Watching and following them is easily one of the best parts of this blog.
Morning & thank you Tk . We had a good coating of snow overnight .
We did as well. I had to look twice in the dark, wee hours of the morning to see if my car had changed from dark grey to white !!
Indeed . It’s weird being home during the day now & more so having Mondays off . My schedule is Tuesday- Saturday so when I get out at 7am Sunday am I’m not back until Tuesday night at 11 . It’s early on so it’s going to be a major adjustment. It’s good for my wife as we are at BI Boston now for an appointment as I can go to most of that now
Thanks TK.
Nice sugar coating of snow last night. 🙂
Good morning and thank you TK.
Thanks TK.
Thanks, TK.
Greece – even the islands – covered in snow. https://greekreporter.com/2022/01/24/greek-islands-snow/
Thanks TK. Fun week of tracking.
Rare to see most major models all onboard with something and starting to be consistent.
Yup. No matter how it turns out. A Big hit, an inside runner, and ots. Still fun to watch. here is hoping for the big hit. 🙂
Thanks TK.
Thanks, TK. I’ll agree with JPD and Hadi – looks like a fun weather tracking week!
Thanks TK !
I am sure this will end up west and deliver rain to a lot of the area. It’s just the way this winter has gone, follow the trends.
I fear the same as well. However, until that is etched in stone,
I hold out some hope.
Quite a Westward shift over6-12 hours with both the GFS and the CMC. Amazing! Before that, the obvious trend was well\
off shore. Now this(#)&(!#&()!)(#)(&#(!)#(*()!
Let’s see what the 12Z runs show.
I hope so.
The 12Z NAMs are advertising an inch of snow overnight, while
the HRRR says, weil mostly a dusting to 1/2 inch or so, perhaps
isolated 1 inch totals.
Thanks, TK
Again, a wonderful story about your Mom on NBC last night. Quite moving!
SAK, you may have said this before here, but, are you ever on WSAR in Fall River? I heard Gary this morning, filling in for Rob.
What stations/networks are normally your responsibility?
Since I usually work at night, I’m not on WSAR most of the time. However, I’m covering the afternoon shift today and tomorrow, so I’ll be doing the live forecast around 12:20 both days, as well as the recorded evening and overnight forecasts.
A lot of the stations that I do are all around the country. Around here, the ones I do are WXEX in Exeter, NH, WMVY on Martha’s Vineyard, and the Renew-FM group of stations (Map of their stations and coverage area – https://renewfm.org/about/stations/)
WSAR Liston live online:
https://radio.securenetsystems.net/v5/WSAR
Thanks!
Where are you heard around the country? Maybe I’ll try to listen in livestreaming off a station’s website. Are you heard in the Caribbean, too?
On my normal night shift, I can be heard at night and/or morning drive in:
Randolph, VT
Bangor, ME
Exeter, NH
Martha’s Vineyard, MA
Renew-FM all across MA/RI/Southern NH
Raleigh, NC
Boynton Beach, FL
California, MO
Commerce, TX
College Station, TX
Langdon, ND
Grafton, ND
Fargo, ND
On the weekends, when I work the morning/early afternoon, there are another dozen or two locations to add to that list.
Quite a line-up! Thanks!
I am going to trying to listen into SAR at 12:20 between classes!
Thank you, TK.
12z gfs a little better, but not there yet.
I like the 12z GFS.
Virtually no snow in Marshfield, to a healthy amount right near Boston.
If I need to see snow, its a half hour drive.
Otherwise …… no shoveling, no impact on my home parking, no cleaning off the car and I can wear flip flops outside of work.
you know that is not the final solution
I do 🙂 🙂 🙂 🙂
What are the wind gusts for the 12z? It seems like a deep storm.
https://www.pivotalweather.com/model.php?m=gfs&p=sfcwind_mslp&rh=2022012412&fh=126&r=us_ne&dpdt=&mc=
That is actual 10m wind, so gusts would be higher
With that kind of pressure, we’re lucky there’s not a stronger high closer to the US/Canadian border in this projection. While there is a pressure gradient, it could be a loss worse.
Love it. My oldest grand wears flip flops all year also and shorts. His dad does as well.
Thanks TK.
12z GFS is a huge hit for interior SNE. Close enough for a period of mixing in eastern MA and RI along and S/E of I-95 but 12-18″ most areas and up to 2 feet in parts of worcester county.

Kuchera Snow:
https://www.pivotalweather.com/model.php?m=gfs&p=snku_acc&rh=2022012412&fh=156&r=us_ne&dpdt=&mc=
Broad window January 28 – February 8 is the regions best time to gain on seasonal snowfall. Part of this includes the transition back toward that milder pattern.
I’ve already accepted the the fact that if I get this seasoned snowfall acceptably correct it’s going to be for the wrong reason.
12z GFS has three more storms after this one…one cutter, one mix/snow event, and another all snow event.
Run total Kuchera Snow with 20-40″ for most of SNE and 40-60″ for VT, NH and ME.
https://www.pivotalweather.com/model.php?m=gfs&p=snku_acc&rh=2022012412&fh=384&r=us_ne&dpdt=&mc=
Not saying this run is correct but it shows how we can still get snow even after the pattern changes with southwest flow/overrunning events
The tides this weekend are growing in range, as we head towards perigee (moon closest to earth in its orbit) and a new moon.
10.6 ft and 10.9 ft Sat and Sun morning’s at Boston.
If we get wind and surge, hopefully it would maximize Saturday afternoon at low tide or even Saturday evening’s high tide, which has a much lower height. (8.9 ft) That’s an extra 1.7 ft of room compared to Saturday morning to accept surge.
FWIW, UKMET has 10-20″ inside of 495.

977 mb, just SE of Nantucket. I hit the like button.
How many iteration will we have between now and event day???
He he he. Should be fun
12z GEFS ensemble mean near the benchmark for Saturday but many members are west of the mean, favoring a Cape Cod track similar to the operational:
https://www.tropicaltidbits.com/analysis/models/?model=gfs-ens®ion=us&pkg=lowlocs&runtime=2022012412&fh=132
Either way I like it and would like to freeze it right there! Too bad this is still a 5-6 day threat.
12z ICON, like the UKMET SAK most above, is further off shore but still a big hit for southeastern MA…
https://www.tropicaltidbits.com/analysis/models/?model=icon®ion=neus&pkg=mslp_pcpn_frzn&runtime=2022012412&fh=129
12z Canadian is a bomb as well…looks like it gets the mix line to 84/495 though:

Maps on Pivotal and TT are delayed today for some reason.
Was just going to mention that. Thanks Mark.
12z GFS has it windy around these parts, but so far not too bad
https://www.instantweathermaps.com/GFS-php/conussfc.php?run=2022012412&time=INSTANT&var=GUSTM&hour=126
For those who want snow, this is NOT good because it speaks of a large pressure gradient that’s missing, because there is not a great cold high to our north, as currently projected.
All about track this time of year. euro so far looks terrific.
Euro is a major blizzard for eastern New England simply put. Perfect track. 1035 high l, all the ingredients.
https://www.pivotalweather.com/model.php?rh=2022012412&fh=126&dpdt=&mc=&r=conus&p=prateptype_cat_ecmwf&m=ecmwf_full
Pressure down to 958, batten down the hatches.
12z Euro would be epic, and looks like an 18 hour storm. Raging blizzard. At 958mb however, would be pretty devastating for the coast with high winds and coastal flooding.
Snowmap at 10:1 would be 12-20″. I presume Kuchera numbers would be higher in most places:
https://www.pivotalweather.com/model.php?m=ecmwf_full&p=sn10_acc&rh=2022012412&fh=144&r=us_ne&dpdt=&mc=
+1 that would be something.
994 to 972mb in 6hrs = BOMB
I can’t wait to hear what JPD’s has to say about that run! His excitement is awesome!
I can’t wait to hear JPD’s words after that Euro run!
This is where TK, SAK and others get us off the ledge 🙂
I will not get too excited about the Euro.
I will not get too excited about the Euro.
I will not get too excited about the Euro.
I will not get too excited about the Euro.
I will not get too excited about the Euro.
I will not get too excited about the Euro.

Ha
I have a kid for detention. I am having him write this on the board.
Hahahahaha 🙂
I heard your 12:20 live cast on SAR. Nice job.
LMAO !!
love it. Almost can’t help yourself.
Trying not to get excited this far out, but it’s hard not to be a little hopeful. Just need to keep reminding myself this thing is ages away, relatively speaking.
Storm modeled so powerful on the Euro it has a warm core center….
https://twitter.com/ryanhanrahan/status/1485681372656250886?s=20
I am hoping we get some snow out of this storm threat Saturday. Things look encouraging but still time for things to change.
Eric Fisher

Confidence increasing for a powerful nor’easter to develop on Saturday
Being 5 days out there are the usual questions of exact track, where highest totals may be, etc still in flux
https://twitter.com/ericfisher/status/1485684386871787526?s=20
12z EPS ensemble mean agrees with operational on a massive hit/near benchmark track.
https://www.americanwx.com/bb/uploads/monthly_2022_01/61eef7c8438d0.png.a996eb7cf9ea2f17b52fafa2305d2c8e.png
988 mb on an ensemble mean at this time frame isnt too shabby.
I’m we better get a registration on the Richter scale when Jp Dave sees the euro. I am will be checking with the US Geological Institute.
I saw it awhile ago. Not going to get anything out of me as it is too early.
However, I am polishing off the Holy Crap Batman And the Cowabunga just to be ready in case they are needed.
I think with ratio, Euro would have 2 feet plus across Eastern sections!
if 15 to 1, then 30 inches plus!!!
That is my kind of storm. Now we just have to get it in here.
Sorry for the fat fingers on the phone :). Missing letters.
I just saw the Euro! As we all know, 5 days out, it’s a LOCK!! 🙂 🙂
Sometimes I like the animations.
https://meteocentre.com/numerical-weather-prediction/map-animation.php?mod=ecmwf&run=00&stn=PNM&map=na&lang=en&mode=latest&yyyy=latest&mm=latest&dd=latest
One thing with this system is that it is moving very quickly with no blocking in place. So the window for very heavy snow, if everything worked out, is not going to be long enough to see those epic 2-3 feet Nemo snow totals. We are probably capped at 12-20″ with up to 2 feet in the jackpot/banding areas IF everything comes together perfectly.
That said, the Euro solution is so intense that it could literally stall briefly and do a cyclonic loop as it bombs out. I am a bit skeptical of a solution that extreme…950 mb noreasters at the benchmark are pretty rare!
Blizzard of 2013 the NAO was slightly positive. You don’t always need a negative NAO to get blockbuster snowstorms here.
Let’s see. ON the total qpf chart for the Euro, it has 1.93 inches for Boston or very close to it.
at 10:1 that of course is 19.3 inches
at 11:1 it is: 21.23
at 12:1 it is: 23.16
at 13:1 it is: 25.09
at 14:1 it is: 27.02
at 15:1 it is: 28.95
So what would the ratio be on this run?
500 mb temp about -23C
700 mb temp about -8 C
What would it be in snow growth region? Somewhere between those 2 heights, approx 10,000 to 18,000 feet. I am not sure the exact height and I am sure it is different each event.
I’d say we would be looking at ratios of 12:1 to 15:1 IF and Only IF the Euro verified. So that is 23-29 inches.
Of course, this is a pure guess, optimistic that it may be. 🙂
It was just a fun exercise.
Best “beyond 3 day” signal I’ve seen in quite some time. Note that both times this has happened it has involved a system that had energy/moisture from pretty far south. The guidance keyed on a significant storm for MLK Day pretty far in advance (big track issue aside, it still had the idea of an important storm). This doesn’t guarantee anything, but it is definitely a tiny bit less of an uncertainty than many other systems/threats have been.
Good to hear. thanks
I have a better signal. Just as I sent Eric’s link that marks shared to my kids, Macs and my song came on the radio 😉 🙂
🙂
Bread and Milk run time!
https://www.youtube.com/watch?v=i6zaVYWLTkU
I’m looking for extensions for the generator. I think the ones we have are still attached to Christmas lights and buried under snowice 🙁
12Z Euro Loop, another example.
https://ibb.co/bjtSCMP
Pretty impressive, for sure!
Its going to happen as im no longer in New England. Both Gfs and Euro have going to a warm core system if I am reading the models correctly
Cold core. This won’t be a tropical cyclone.
I wonder if we will se someone with a snow map tonight.
IMO it would be too early for anything more than a map that says something like “significant snow potential”. I wouldn’t even bother today. Not up to me of course. 😉
I won’t name the source but somebody was showing model numbers last night for Saturday (day 6).
My early call map would have 0-30 inches. A can’t miss forecast.
I have seen early-on snow maps that carve out areas with words such as light potential, moderate potential, and heavy potential
But we all know why.
I definitely agree with the sentiment that this is the best day 5+ storm signal in a long time. But there seems to be a little too much blind faith in the models going on because of that. We’ve been preaching all winter to use a lot of caution beyond day 3. The relative degree of model consistency with this threat doesn’t really change that for me. There have been plenty of times where the models have fallen into a “group think” philosophy with systems like this and failed.
I think there will ~probably~ be a strong storm somewhere near the Eastern Seaboard come Saturday, but we won’t know much more than that for at least another 2 days. IMO, at this early stage, the bigger risk for missing out on snow in SNE would come from a track that’s too far west, bringing rain into the equation…
SHHHHHH you are now banned from WHW for speaking the R word! SHHHHHHHHHHHHHHHHHHHH!!!!!
Oh you’d better believe I’m sticking with my day 3 rule, still, despite the “signals”. I’ve already had at least 3 private messages from people asking me how much snow we’ll be getting. 😉
I like the 0 to 30 inch call by JPD. That may indeed verify.
SAK, thanks for sending us the list of cities where you can be heard.
I’d advise people to NEVER even attempt to do what this idiot did on the German Autobahn. He drove a Bugatti 417 kilometers per hour (that’s 260 mph) and recorded it. He has since been arrested. https://www.youtube.com/watch?v=7pg1hhW5qhM
If this materializes, Eric Is worried about coastal flooding
I did note that Eric considers Saturday day 5
Starting with late afternoon forecasts on Monday, Saturday will move to day 5. For morning updates, it’s day 6.
For example, my forecast this morning, which included today (day 1), Tuesday (day 2), Wednesday (day 3), Thursday (day 4), Friday (day 5) for section one, and then days 6-10 were Saturday through next Wednesday, etc.
If that forecast is updated now, today is largely over, so the new day 1 becomes Tuesday, making Saturday the new day 5. 🙂
That is why Eric is referring to Saturday as day 5 now.
🙂 🙂
Sorry hit send too fast during a rousing game of go fish with granddaughter Eric’s forecast was early afternoon. Way too confusing
He probably figured that it would be seen more late in the day, essentially counting today as “mostly done” so advancing Tuesday to day 1. I’ve done that myself a few times.
And that is yet another layer of confusing.
I usually like about 3PM as a general cut-off time if I had to choose one. My explanation above is probably about as clear as we can lay it out. Basically this morning, today is day 1.
Tonight, tomorrow is day 1.
I guess it’s where do we decide the change is? Usually the whole day 1, day 2 thing was always kind of used between forecasters and we just had a general unspoken rule that sometime around mid or late afternoon we stopped thinking of today as day 1 and started thinking of tomorrow as day 1 instead. I think it was probably based on when the NWS updated their zone forecasts and “TODAY” was gone, and it started with “TONIGHT”.
That’s how my seniors / mentor went by it in the private sector as well. 🙂

All signals are pointing toward a major nor’easter near the coast on Saturday. A blizzard is possible somewhere in New England with strong winds and heavy snow totals. How much in CT specifically? Too soon to tell but it could be a big one. #nbcct
https://twitter.com/ryanhanrahan/status/1485698589485584395?s=20
Kevin L’s Ch 25 FB post from 3 hours ago is exactly how this should be done today for mainstream media’s social media pages, IMO. Very nicely laid out and explained. No room for confusion there.

18z GFs running. Bet it comes west and no reason to freak out.
My bet is east and a little faster. 😉
Yep it’s further East . Not a guess now since it’s showing that.
I just saw that. No double-digit snows except outer Cape Cod and Maine.
That is a given? I’m trying to avoid buying more extensions
has boston as a foot.
Actually it looking A lot like the euro so far.
Windshield wiper in action. Keep to me is system is there. Details will come in to picture slowly.
Pretty much as always. 🙂
Day 3 rule. In the mean time, take your dramamine and enjoy the ride! 😉 hehe!
Harvey showed 2 possibilities on track, either off the coast at the benchmark (snow) or hugger (snow to coastal rain).
I guess that means that OTS is not an option?
There are more than just 2 possibilities on a track, so yes, that’s still an option. So is an inside runner. ALL of those options are on the table. There’s actually a RANGE that counts as the possibilities. But on TV they will often show it that way for the sake of simplicity.
18z ICON is 973mb at the benchmark…
https://www.tropicaltidbits.com/analysis/models/?model=icon®ion=neus&pkg=mslp_pcpn_frzn&runtime=2022012418&fh=120

Hmm same shot. Sorry. this time it looked more East and South. tired eyes???
OK strike that…..replace with “in the vicinity of the benchmark” 🙂 Pretty close though.
All I know is that I see a beautiful deformation band across eastern CT into Worcester County.
If it is beautiful where you are, my guess it will be here also.
Nah, I was being a bit of a dick. 🙂 I knew what you meant.
Every now and then, I get like that. My bad. I am sorry.

30″ for Boston and most of eastern MA using their ratios.
Love it. Then my analysis earlier was pretty close.
thanks
Nice.
Mark I hope that band comes over to my part of CT. It looks real nice for your area at the moment.
Way too early to get excited about that….a solution like the 18z GFS (or worse) is still entirely possible.

CIPS analogs showing a 40% chance of at least 1h of blizzard conditions for eastern #MAwx for Day 5.5 – Saturday evening, Jan. 29, 2022!
https://twitter.com/AlexJLamers/status/1485744139392229377?s=20
Using the CIPS analogs, the top analog based what on what the GFS is showing right now is March 3, 2009. (This is based on about 15 different parameters). That storm dropped 6-12″ on the region.
The Top analogs are:
00z 3/3/2009
00z 2/15/2007
06z 2/5/1995
00z 2/11/2005
12/z 1/16/1983
06z 2/17/1996
06z 2/14/2014
12z 12/16/1981
The analogs also show a 30-40% chance for blizzard conditions for at least 1 hour across most of eastern Mass.
LOL, we are thinking alike.
That Valentines Day 2007 storm was a monster and dropped 30″+ across portions of eastern Upstate NY. Here in CT though, we literally had inches of sleet along with some snow. Heaviest stuff I have ever had to remove from the driveway. No desire to have a repeat of that.
Mark, that was my last year at Siena and was living in Troy at the time. Massive storm. I remember going out to my car in the morning to get to work at Albany Med and my car was entirely buried on the side of the road, all I could see was the antenna.
Yeah, there was a huge deformation band across eastern Upstate NY with that one. My parents in Amsterdam got 35″ and there was a swath of 40″+ just to the west. Heck of a storm….

28″ for Boston with a dropoff to virtually nothing a few miles southeast of the City. That seems plausible!
12z EPS probability of greater than 12″ of snow is greater than 50% across much of the region:

Haven’t see a map like that in awhile. Impressive for 5 days out…
I hope snow lovers are not disappointed. I work for a funeral home it’s so hard to reschedule with church and cemeteries and hard for our families to get final closure. Also for my coworkers we have to extremely careful after the snow ❄️ stops melt and refreeze in the parking lot.
I wish you the very best. Snow is so difficult for many. I saw the potential for coastal flooding for this also which always breaks my heart
I totally agree.
Hugs
Pretty decent jump east on the 18z GEFS as well. Most of the ensembles followed the operational east

Nearly every one of those members is a bomb either near or inside the benchmark. Huge hit.
Mark, thanks for sending the maps. One of them has probabilities of more than 12 inches, I believe. Parts of Eastern New Brunswick, Canada, are in the 100% probability zone. Am I seeing that correctly, or is my slight color blindness a factor?
Highest is 80-90% in that area
I find this possible Saturday event interesting ……
Surface wise ….. looking btwn 84 hrs through 120 ….. different than other systems this year, I think
The projected surface map looks rather benign at 84 hrs (late Thursday). Its not like there´s a big area of rain and snow gathering in the central US or the Gulf coast that you might see 2 days before a big hit in New England.
I think a big player is this projected narrow ridge poking up on the west coast and how much a disturbance rounding the east side of the ridge really deepens a downstream trof. The trof than directs what is initially some moisture and maybe a low sitting over the Bahamas and lifts it NNE, exploding it potentially.
Just have to know the amplitude and location of the western trof and similarly, what the downstream trof´s amplitude, location, etc will be to know how it will influence the strength and track of the low.
last paragraph, western ridge
Thank you, Tom
Interesting and thus will be a fun week
For sure.
In the meantime, I really noticed 5pm light tonight, which was really nice.
I did also. I have indoor fairie lights that go on and off on schedule and I will have to change all very soon
Glad I was finally able to sit out by the fire last night. Flurries tonight
Comparing the 00z NAM´s 84 hr (500mb) chart to the 12z EURO´s and 12z GFS´ (500 mb chart) ….
they all have a fairly similar western ridge, they all have a jet streak coming atop the ridge in Central Canada and they all have developing trofs around the Great Lakes.
I would say of all 3 features, their Great Lakes developing trofs look a bit different.
Start of 00z GFS about a half hour away. 🙂 🙂 🙂
Honestly a lot has to go right for this to happen. We have no blocking in place, the trough really has to dig to get a Euro solution. My confidence is below average on this one.
We are developing a nice coating…..closing in on half an inch
Tonight’s snowfall is going just as expected.
Colleague of mine forecast 2-4 inches. Oops. That’s not going to work out. Been there, done that… 😉
As of 1:00 a.m. I have 0.4 inch at Woburn.
From my untrained eyes Euro still looks like a big hit on 00z run.
Good morning. A bit more snow here in Coventry CT this AM than I expected. We have about 1.5” and the plow has been by twice.
Regarding the late week storm, the 6z GFS and 0z CMC are now more of a sideswipe while the 0z Euro is still a huge hit with a raging blizzard and 15-24” for pretty much everyone. 6z Icon is a big hit as well with 12”+ but mainly for eastern MA.
0z Euro

Ratios would be higher however so need to add several inches to these amounts.
Here’s the F5 snow map with ratios:

Euro wind gusts would be devastating for the coast..

Sorry these are the surface wind gusts…up to 85 mph on the coast:

Actually that’s knots… 85 knots would be nearly 100mph! Yikes.
6z GFS Kuchera snow:

A bit more than a sideswipe for eastern MA…still delivers 20” to eastern MA and a foot back to me.
Thanks for posting the maps Mark. I too ended up with about 1 1/2” of fluff.
Good morning fellow model watchers.
6z gfs concerns me. not liking that off shore track Hope it is an outlier and not a sign of things to come
Also, look at hour 84vof 6z Nam.
My eyes may be deceiving me, but looks like a new cold Canadian high is beginning to move in with a period of snow. Would this contribute to an off shore track???
I am beginning to think that an inside runner/coastal hugger may be off the table and we are looking at a direct hit or side-swipe or complete off shore miss.
Can’t wait for the 12z runs.
Inside is not completely off the table as this is still a day 5 threat now. Can probably rule that out within 24 hours.
ECMWF is a bit of an outlier as it has an unrealistic loop in this pattern – not entirely impossible but also not very likely.
UKMET looks too intense to me.
GFS / CMC more realistic at this point, but we still have a long way to go.
Blend euro and GFS and we get an 18-24 inch system.
Euro stalls and is a once in 10 year system. 00z GFs was much closer than 6z GFS. It’s been jumping slightly drop run to run.
New weather post…
