Weekend Update #1

282 Comments

11:32AM

SUMMARY…
Time to focus on the well-advertised long-duration snow event. The set-up has been described in previous entries but let’s review quickly. An arctic cold front settles southward across southern New England today and then sits just off the South Coast for the rest of the weekend as a couple waves of low pressure ride along it, producing periods of snow, first very patchy and light this afternoon then a little more so tonight and Sunday, then with the most widespread precipitation coming Sunday night and Monday as a final and slightly stronger wave of low pressure moves along the front. This final wave may come a little bit closer, enough to introduce mixed precipitation to South Coastal locations, but at this time I don’t see any mix coming further north than that as the cold air will be a stronger force, aided by a deep snow cover across just about all of southern New England. Snow amounts from the entire episode are about to be listed below and I will try to re-visit them by time period in the forecast that follows this summary. It’s important to note that there can be large variations in snowfall across the region, not only due to the somewhat disorganized nature of the precipitation associated with these disturbances, but also due to ocean-enhancement which will likely be a factor near the eastern coastal areas of MA and NH, and then the mix factor possibly being involved near the South Coast later in the event. ***TOTAL ACCUMULATION EXPECTED FOR EVENT FROM START TO FINISH: 2-4 inches immediate South Coast, 4-8 inches just away from South Coast from central RI eastward across Upper Cape Cod, and 8-16 inches elsewhere, and spotty amounts above 16 inches are likely along east coastal MA and NH as well as a few towns on eastern slopes of higher hills. There are some signs that the entire event may try to wrap up a bit earlier than previously though, but for now will leave the chance of snow showers in eastern NH and MA into Tuesday morning especially Cape Cod due to cold north wind over relatively warmer water behind the intensifying final low pressure wave. A quick “break” comes later Tuesday and Wednesday as a narrow high pressure area moves in, though it will be fairly cold but not frigid. A clipper low pressure system and attendant Arctic front comes through the region next Thursday with a minor snow event, but opens the door for a major cold blast to end the week.

SOUTHEASTERN NEW ENGLAND FORECAST…
TODAY: Clouding up. Patchy light snow possible this afternoon with less than 1 inch accumulation. Highs 25-30 southern NH and northern MA, 30-35 to the south, then falling slowly during the afternoon. Wind light SW shifting to NW then N from north to south across the region.
TONIGHT & SUNDAY: Overcast. Periods of snow, mostly light to moderate. Accumulation 2 to 6 inches through this period with locally heavier possible in parts of northeastern MA and southeastern NH, and areas of below 2 inches closer to the South Coast. Temperatures nearly steady from 15-20 southern NH to near 30 South Coast. Wind NE to E 5-15 MPH.
SUNDAY NIGHT THROUGH MONDAY NIGHT: Overcast. Steadier snow, mostly light to moderate with a few heavier bands favoring east coastal areas of MA and NH. Additional accumulation of 2 to 8 inches from south to north with locally heavier possible in parts of northeastern MA and southeastern NH. Also, sleet/ice/rain mixing near the South Coast at times. Temperatures nearly steady ranging from the upper 10s northern MA and southern NH to lower 30s South Coast. Wind NE to E 5-15 MPH, higher gusts, later Monday, shifting more to the NE and N Monday night.
TUESDAY: Early snow showers especially eastern areas otherwise clearing. Breezy. Highs in the 20s.
WEDNESDAY: Sunny. Low 15. High 25.
THURSDAY: Cloudy. Snow or snow showers. Low 20. High 30.
FRIDAY: Sunny and windy. Low -5. High 10.

  4. Made a quick edit as I left out the line about the mixing in the forecast part. Oops. And I had to add the word “immediate” before South Coast in the accumulation section because I really do think that you won’t have to move too far away from the South Coast by the end of the event to have 4+ and go up from there as you head north. The gradient has the potential to be quite sharp there because of some mixing and even somewhat less precipitation for part of the event.

  5. I am out. No snow yet.
    Grocery stores not bad.
    Whole foods and roche bros.
    I am very pleased and surprised.
    Maybe public had no clue how bad its going to be

    1. It’s actually not going to be that bad, compared to the previous 2 events, and people probably still have enough supplies for the rest of this Winter AND next Winter from over-preparing for the last 2 storms. So the stores shouldn’t be that bad today. 🙂

    1. No problem. Rest up today if you can and be safe when you are out there. You’ll find this much easier to deal with in terms of snow rates compared to the previous 2 bigger events, just long-duration and of course space issues with existing snow banks.

  10. MJO has been between phases 7 and 8 which are snow phases for this area (no surprise) since late January. MJO is forecast to mill around in phase 8 and head into phase 1 (also a snow phase) through February 21.

    I think the forecast of a snowy February is already an understatement given what has taken place already and what is coming up now. 😛

    I do think our threats of the big events start to drop off as we head beyond next weekend but the snowy pattern overall is not done yet. One thing I am missing big time so far this month (based on my November forecast) is the temps. Adjusted that of course heading into late January as we talked about on the blog, knowing that it would be a colder pattern contrary to the original forecast. So the cold wins out this Winter, despite the mild December, if you include November as part of the overall Winter season. 🙂

  11. So, NWS radar shows dark green echoes over me (moderate) yet I have a few fine flakes falling and visibility from the top of my hill of 10+ miles (I can see the buildings of Boston). Dry air is certainly in place and gobbling up the snow as it falls. And the upstream radar echoes are diminishing. That solidifies the forecast of “not much during the daylight hours” for today. 😀

      2. It will limit things today. It’s doing that now. But only so long until you moisten up that atmosphere enough to overcome it, especially with the lack of additional dry air pushing down. Increasing fetch off the water with time…… you know what that means.

  14. While the impacts will be drawn out and probably not horrible for travelers, keep in mind that this is going to be difficult for the sand and plow truck drivers. Long stretches of work, short rest periods between rounds.

    Those guys and gals will be very tired come Tuesday morning. Be sure to give them extra space to work and to give them a break if things aren’t done perfectly.

    They don’t want to be dealing with this stuff at this point any more than the rest of the public.

    If you get a chance, thank your local plow driver. You’d be surprised how just a little recognition goes a long way in keeping them going.

    OK, stepping down from soapbox now.

    🙂

  24. 12z Euro looks about the same as it has… 10-14″ for all of MA except the Cape, on a 10:1 ratio. QPF about 1-1.25 inches.

  28. Out and about again.
    Steady light snow, occasionally bordering
    On moderate. In poor signal area. Radar would
    Not load

  29. on and off light snow, no accumulation yet, but been steady light to a few bursts of moderate, coatings on the cars. I believe its more to do with the fact that snow is blowing off of the marsh. I can see light bans of snow coming from the marsh while my friend just down the street has not seen a single snowflake.

  34. Winter Storm Warning up yet again for much of SNE. I’ll be interested in the new accumulation map they’ll put out later. The warning mentions a possibility of an 18-24″ band from Boston to Bedford, Beverly, and Lawrence.

    1. * SNOW ACCUMULATIONS…12 TO 18 INCHES THROUGH LATE MONDAY NIGHT. A LOCALIZED BAND OF 18 TO 24 INCHES OF SNOW IS POSSIBLE NEAR THE BOSTON…TO BEDFORD…TO BEVERLY AND LAWRENCE CORRIDORS IN NORTHEAST MASSACHUSETTS THROUGH LATE MONDAY NIGHT.

      Hmmm right out of the NAM???? Gfs to a certain extent also.

  36. I don’t know if there is an answer for this but why have all the storms been such big snow producers when all is said in done. This will be the third Monday in a row with a significant snow storm.

  41. Being out and about today, people are already wondering “where is the snow?” and expecting the entire amount (which in some cases is being over-forecast) to be on the ground before the event really gets going. Called that, not that it was hard to do. 😛

    They also seem to be we’re about to be in for a blizzard or a storm like Monday with lots of wind and blowing snow. Nope. Plentiful snow producer for a good part of the region, especially the ocean-enhanced areas, but that’s about it. Media is quite successful at programming the general public’s minds. 😉

      1. On the larger scale, yes.

        I think their max amounts can occur in a few areas, but I do not think they will be that widespread. They are depending a WHOLE LOT on the ocean for this, and to be honest with you the ocean can be almost as tricky as a norlun trough.

    2. Media may be part to blame but I think minds have a mind of their own, if you will. I’ve said same to several folks who, for whatever reason, prefer to be in “we are in for a massive blizzard” mode

    3. My reaction from people was actually the opposite. I heard many 2-4 inches, not a big deal discussions. We should probably get those folks to meet somewhere halfway!

      I do think the impact will be felt on a large scale in the city. Public transportation will most likely be heavily effected, and businesses will be faced with tough decisions. After last Monday’s storm, where many traveled to work and back in hazardous conditions, id imagine employers will be thinking twice about this one.

  42. I had mentioned yesterday I think and not sure if I got an answer. Is the wild card in this entire event being on whether ocean enhanced snow takes place?

    1. I think that image was part of a fb post somewhere mentioning the new GFS has had a cold bias for 2m temps once they get to down to a certain point. The GFS has been showing impressive cold but my understanding its overdone. It will be cold but the Boston record low is safe

      1. JMA and Tk seem to think it’s going to be quite cold here next weekend I believe JMA showed some concern for this yesterday.

        1. Very cold yes, but just pointing out a bias in the new GFS and Boston;s record low of -18 most likely wont be touched

  45. NortheastWeatherHQ retweeted
    Jeff Smith ‏@JeffSmithABC7 4m4 minutes ago
    @NEweatherHQ I think the 00Zs will be very telling since the piece of energy will be fully onshore in the Pacific NW (well sampled data)

  46. Wankum has jackpot area north of Boston. 10-14 in the Boston area and a good swath of South shore.

  47. FWIW, the GFS still wants to NAIL us on the 13th with another foot of snow.
    WOW!

    Been pretty consistent on this. We shall see.

    1. On everything except the date: 16, 14, 15, 12, 13. It can’t decide which system is dominant. Then it picks one and can’t quite place it. But there’s lots of time. Neither one will likely be a major snow producer though. Upper low may be driving SE way too fast for that.

        1. The GFS has that system developing like that one a couple weeks ago that we thought was going to nail us but didn’t develop in time.

      1. Too much uncertainty with that one. The forecast above is low confidence regarding that part of the week.

  51. My florist thinks that it snows every year just before Valentines Day so I’m going for the13th for our next storm.

      1. Perhaps! (I’m admittedly a bit focused on my own area, which is the south end in the city). It will all depend on the strength of that ocean effect.

  53. People have been talking about GFS consistency. Well one thing it has been consistent about over several runs now is a decent rainstorm on Monday Feb 23.

      1. And everything in the City along with it.
        We don’t need no stinken rain at this point. What we need
        is a slow/steady melt. Say temps in the low to mid 40s and just let
        it go ever so slowly. No 50s or 60s, thats too much. No heavy rain either. A light rain would be fine.

  54. Snowing lightly here again. Wife and I are headed to see a movie in a bit.

    “Black or White”. Looks great. By the time we decided, the only place we could get
    tickets was Randolph. (we could have at Dedham, but show is too late at 10:35) Oh well it’s not too far and I’m not concerned about this wimpy snow. 😀

  55. I’m seeing some indications of a pattern shift 10 to 15 days from now, with daytime highs in the mid 40s to low 50s a distinct possibility. We’ll need it at that point to wash away some of the snow. This won’t mean, of course, that March will be meek and mild. But, I think the last week to 10 days of February will be.

    1. Lean toward the 15. They usually happen later than advertised especially if you see it on GFS. But other models are not immune to the early shift issue too.

    2. Been of the opinion of a change around the ~25th. Mostly because I tend to have a bias towards slowing down pattern shifts but I could see that change being closer to the 20th than the 25th. How about it being ushered in with a soaking rain on or about the 23rd?

      1. That’s my concern. GFS was consistent for a really long time with the February 2 snow (and had it first). It’s doing the same thing with that rain system.

        Ideally, and it goes without saying, several mild and mainly dry days would work out best with a gradual melt especially off roofs and having time to get storm drains open. Not sure if we’ll be granted that wish.

  56. Gil Simmons NEWS8 CT ‏@gilsimmons 1m1 minute ago
    Snow coming through the state midnight through 4/5 AM. Dusting to 1.5″ for most with some 2″ or maybe 3″ totals near the Mass. line.

  57. I like Pete’s snowfall map and that of the NWS. I can’t believe I’m actually saying that because I tend to take both sources with a grain of salt; however, this is how I envision the event to unfold. Widespread 12-18 inches with isolated 2 ft amounts!

      1. Almost feels sad that those who criticize him don’t understand he is right more often than not….. 😈

        1. You had to eat turkey last year too …..

          Actually I don’t get the criticism of any mets on here. It’s what the folks on the BZ blogs do. But then it is just my opinion and I know comes as no surprise to anyone. 🙂

  58. Gil Simmons NEWS8 CT ‏@gilsimmons 12m12 minutes ago
    We need to watch Thursday’s low pressure center and then unbelievable cold next weekend. Raw guidance showing -20 temps possible in CT!

  59. Still think the next covering starts after 9PM in the Boston area, in fact probably after 10.

      2. We get a fairly slow 3-6 inches during the day tomorrow, steadiest in the morning, but we have to keep an eye on the coastal band that may set up.

  61. Had not logged on to WBZ comment section in a while, and today I was again reminded why.
    I can’t tell you how thankful I am to be a member of such an awesome weather blog – WHW!!! You guy and gals are the best!
    Anyone heading out tonight, Be Safe! It doesn’t take much to make the roads slippery and the snow banks are downright dangerous!!

    2. The main troll there refers to this as the “elitist’s blog”. I always thought that was kind of funny. 🙂

  62. looking at the patriots road games compared to home games.
    Home games should be much easier to win than the away games.

  63. If we get little or no melting before a rainstorm that would be an epic disaster for many. Let’s hope that doesn’t come to fruition.

  64. I saw channel five is already posting on Facebook about the possibility of more snow on Thursday. How bout we get through this one first?!?!

  65. 0z NAM in for plenty, mostly coming Sunday night into Monday. Still running.

    I’m sure SOMEONE will say precip is overdone…on all models. 🙂

  67. Dave Epstein tweet.

    @growingwisdom: It would not surprise me if driving is banned in Boston after the two days of snow is over.

  69. The best pressure rises seem to be in Maine …..

    I dont know if I fully agree with the idea of a coastal front, where its 30F along the shore and 18F inland tomorrow.

    I wonder if this arctic front is going to behave like a backdoor cold front tomorrow, where its 15F at Logan tomorrow afternoon and milder as you get into southwestern New England.

  72. Was out. Went into movie at Randolph, not snowing. Came out at 11:30PM snowing hard.
    Roads were a MESS all the way home. NO SALT TRUCKS OUT AT ALL.

    Snow let up a bit. Watched TV going to bed now. SNOWING HARD again. About 2 inches so far.

    Later…

  78. Just did the math. 68.4″ at my house since and including Jan. 24th and including so far this morning. That’s nuts.

  79. Tom,

    What’s the Euro & GFS look like for Thursday? You say they are south of here but do you mean their OTS or a hit?

    1. Don’t know about EURO but the gfs does not show a miss… But TK mentioned gfs has difficulty with placement on these types of systems.

  84. Snowing lightly in Sudbury now. We have 3 inches of snow and they just started plowing our parking lot! Didn’t hear plows all night.

    I hear what sounds like a phoebe singing outside. I am hoping that the animals are ok outside – this has been and continues to be a bad winter.

    Don’t know if anyone posted this info. yet, but on NECN this morning they said Kansas(I think they said Kansas) was 82 degrees yesterday. And the west coast of the US is getting heavy rains. The weather is getting kind of scary. Maybe it’s happened before in history, but it still is rough.

    2. Rainshine I was pretty sure I heard a phoebe the other morning also. I cannot get to my feeders and also hope they are ok.

      Brother in law lives just east of San Francisco. When we spoke to him a couple of days ago they were expecting double digits of rain. It is their rainy season but all at once will cause problems.

    4. This particular pattern has happened many times, actually. We happen to be in the core of the snowiest and some of the coldest this time around.

      This one is driven by a particularly strong and somewhat stable pattern of teleconnecting negative height anomalies from Siberia across Greenland and right through eastern Canada to here. The most direct route possible. More often our cold snaps are taking a little longer route through western and central Canada and arriving via the Great Lakes.

      The West Coast rains were foreseen for a while and is a variation on the “pineapple express”.

      The anomalous warmth in the center of the country is nothing more than a response to the anomalous cold here in the Northeast.

      These days, we are made hyper-aware of every detail in every location via mainstream and internet media sources that exist in excess. This didn’t happen in many previous decades when the same things were going on with just different little details here and there.

    1. Tj, looks like the EURO has the system in about the same position as the GFS, just south of New England. Yesterday, it had it passing to our N and W.

    1. We have not even gotten a quarter of an inch so far, heading to Patriot place for breakfast, all have a great day 🙂

      1. We got about 1/4″ yesterday. Woke up to 2″ here this morning, I assume Foxboro is about the same as I’m about 3 miles from patriot place.

          2. Earlier comment by TK…
            “-Less than 6 inches of new snow by Sunday afternoon in some locations. This will cause many people to declare the entire episode a failure, as usual, without actually waiting until the episode is complete. This, I think, is beyond laughable.”

            1. I hope you don’t mind me reposting your comment, TK. I just could help myself 🙂 it was a perfect fit!

              1. You are free to do so. Besides you used quotes and gave me credit so you’re safe from a lawsuit. 😉 heeheehee
                I was ready to hire Katy Perry’s lawyers. 😛

  87. Portland, ME : 11F, Portsmouth, NH : 17F.

    How long with the upper 20s hold in southern New England ……

    1. Thanks Tom.

      I guess we are in one of those lulls. Not much happening. After considerable
      eye strain, I was able to see a few flakes still coming down, but that’s it.
      Basically nothing happening here at the moment.

      Here’s a snow map just posted by Dave Epstein. Isn’t it something that
      between now and Tuesday they can get it precisely to the tenth of an inch. Amazing how they do that. So this is obviously the output of ONE SINGLE
      computer model:

      https://pbs.twimg.com/media/B9UF27_IcAAm4VQ.png

      3. So, I think I saw Hadi mentioned that Logan is reporting 3.7 inches ….

        Implies they expect about another 19 – 20 inches, with the ocean enhancement helping out.

        I guess they must expect the temps to drop dramatically because I dont think we could get the ocean enhancement at the current temperatures.

        1. Yes and No. What are the 850MB temps?
          If I use the NAM, it’s about -6C or 21 over the ocean
          out there. Ocean temp about 40? that’s a 19 Degree
          differential, so it’s possible. Would be better IF colder.

          We shall see.

          It’s 29.5 here, after sneaking up to 30 a bit ago.

          Weill be watching that thermometer.

  88. O crap spoke to soon, there’s 2.5 inches here, didn’t look like that through window, just sanders out

  90. Also noting that Boston and Beverly’s current 8am obs showing strongest winds in region, with gusts over 20 mph. Rest of obs show winds much weaker. Perhaps the surface, colder air making its move ??

    1. Perhaps. Keep watching.

      Oh by the way, had a peek at the GFS out to 16 days.
      It looks like MORE Shenaniganson the way!!! Although some
      action is depicted as just OTS or grazing, it’s so far out there that
      they way it has been going this year, We may be in for it.

      Is this going to be a RECORD SMASHER of a year?

      1. Its crazy OS !!

        My concern is the clock is ticking …..

        Its Feb 8th, in 3 weeks, the sun will be at 40 degrees above the horizon in New England.

        Two weather trains, if you will, are going to be building with opposite forces.

        We are evidently headed towards amazing snow depths, while climatology starts to move us towards an inevitable warmup, that if and when the pattern flips, could be quite dramatic, especially if it arrives in March.

        1. SPRING FLOODING is definitely on the table. We’ll have to watch for that after we get through all of this!

          1. You love weather inconveniences, anything to inconvenience the human, yes we have no control over it, but rooting for any inconvenience for humans is bad, bad for the soul 🙂

            1. Nah …. None of us love or are rooting for the bad weather impacts ….

              But to not plan or anticipate for the possibility of them is not a wise choice either. 🙂 🙂 🙂

  92. This storm is going to have serious surprises. With this many variables in play, it’s inevitable that something is not going to go according to plan. No telling whether that results in more or less snow though. In general, I would say that the NWS snow map is overdone. 18-24″ should be reserved for the North Shore, with a general 14-18″ elsewhere, less to the south. But it’s going to be interesting to watch, we don’t see too many like this.

      1. North Shore. Ocean enhancement. Pretty much every forecast has that. Down in the Wrentham/Attleboro area, I’d expect about a foot or a little over. And again, it won’t all be on the ground for another 48+ hours.

          1. WeatherWx.

            Sounds like the name of a rap artist.

            “I’m Flavor Flav!”

            “I’m WeatherWx!”

            See? It has a ring.

  96. Just for fun, I checked the SNOW totals we posted in November.

    Here are the top ones:

    Old Salty 94.6
    Tjammer 67.6
    John 67.5
    Shotime 62.2
    Hadi 56.8

    Didn’t realize I had the highest totals.

    I MAY end up low. 😀 😀 😀

      2. My Apologies, Must have picked up an earlier version.
        Here are the top predications:

        WeatherWiz 100.1
        Old Salty 94.6
        Cat966G 70.0
        Tjammer 67.6
        John 67.5
        Shotime 62.2
        Hadi 56.8
        North 56.7
        bearlb67 56.0
        Haterain 54.0

        1. I was trying to be that guy on The Price is Right who bids a dollar. Never thought 100″+ would even be a remote possibility.

          1. Well it certainly is. May not get there, but it
            seems like a very reasonable prediction at this point. 😀

    1. Most of your snow comes tonight and tomorrow.

      There have been no surprises thus far.
      Read my discussion and other comments that follow regarding the setup of this event. 🙂

  102. Here’s some more snow maps:

  103. Lawrence, MA down to 18F.

    According to obs, winds are picking up from Blue Hill observatory, Boston and points north and northeastward.

    Still very light wind here in Marshfield.

  104. 12Z NAM is cranking Same theme as Tom says.

    MAIN action gets going around 6PM this evening. Not a whole lot of shaking going
    on prior to then, IF you HAVE to get out today, please do so before 6PM.

  105. Not totally questioning the forecast of this event but that HRR output OS posted for today gives me pause. It was advertised as a long duration event with no periods of really heavy snow, more or less a slow gradual accumulation. Not sure how much Logan picked up yesterday but today apparently, 3.7″ so far. The HRR is saying another 3 or so between now and 9pm. That’s roughly 7.” If the high end of the 18-24″ were to be realized, it would have to snow around a foot and a half in basically a 24 hr period between late tonight and late Monday night (tues looks to be like yesterday, very little accumulation). That might be achieved with ocean affect, but all other areas relying on synoptic snows will have a difficult time getting big totals, especially south and west of Boston. TK mentioned high stakes around the formation of a coastal front, but as Tom pointed out last night this set-up wouldn’t necessarily produce that front in its classic location like during a nor’easter. This all points to big bust potential south of a line from Springfield to Worcester to Boston.

    1. Yes and I still have that confusion re : coastal front.

      I propose Boston does well, ocean effect wise, if the coastal front sets up 15 or 20 miles east, out into the ocean. It puts Boston on the cold side of things and west of the boundary. I also propose that, thats what is going to happen. I’m struggling to see how Logan maintains close to 30F.

      I guess yesterday, I got the idea that the thought was the coastal front would set up just INLAND from the coast line. But, then if thats the case, I’d think the snow maxes should be in the Merrimack Valley, not along the immediate coastline.

      It should be quite interesting to see how it all plays out.

  106. Tom, Here’s another interesting temperature reading for you:

    9AM Portsmouth NH down to 13 !!!!!!
    That’s NOT far up the coast at all.

    Other note:

    Manchester AND Concord are at 16

    So your observation that the COLD is leaking down the coast from MAINE
    is SPOT on.

    Here are some MAINE temps

    Portland 11
    Bar Harbor 5
    Bangor 2
    Caribou -7

    1. Thanks OS …. Should be interesting to see the progression the next few hrs.

      It still mild enough here that there’s some water dripping off of the roof and the 3 or so inches that fell last night must be somewhat wet snow because its coated to the trees.

  107. I’m here to confirm your organized ramblings Tom and OS.

    We have some brief bursts of synoptic snow coming from the WNW as a result of lift over the Arctic boundary (stationary front style) now. These taper off again much like they did yesterday.

    Yes indeed that small ocean-effect snow band has come ashore on the South Shore, not the North Shore where that action will be later.

    And most of the snow will fall starting this evening for about 24 to 30 hours, that is, about 75% of the accumulation in most locations.

  109. Temperature is pretty much holding here. Currently at 29.3
    It has NOT Crashed, but did drop a bit from 30 and holding.

    I saw a 34 for Marshfield.

  110. Guessing I will go out once today to shovel then again when it ends on Tuesdsay. Just hats cleaning twice.

    1. I believe I would have to say that is DOWNSIZED somewhat.

      That’s 14-16 inches for Boston.

      I wonder IF 12Z GFS comes in LOWER as well.

      Does this point to what Ace has posted above? Hmmm

        1. INTERESTING Latest Summary from NWS:

          WILL DISCUSS SNOW ACCUMS A LOT MORE LATER THIS AFTERNOON. GIVEN MORE MESOSCALE PROCESSES AND LESS SYNOPTIC FORCING THAT WE OFTEN SEE WITH WINTER STORMS IN THESE PARTS…SNOW AMOUNTS MAY VARY
          CONSIDERABLY ACROSS THE REGION BY THE TIME ALL IS SET AND DONE.

  113. Those of you that are friends with me on my personal FB page have seen this photo but I will share it here. Took this photo just after 10:30PM last night (Saturday) atop Zion Hill on the west side of Woburn MA. Snow was falling and the wind was calm, yet look at the American flag, which froze solid as the wind was extending it and the temperature was crashing after the overnight rain and during the midday snow on Thursday.

  114. Lower amounts would be fine with me at this point! The good thing about having recently upgraded attic insulation is that the snow doesn’t really melt on the roof and we don’t get icicles or ice dams. The bad thing is, the snow doesn’t really melt and just keeps piling up, particularly in the shade on our lower roof.

  115. Latest detail discussion from NWS

    EXPECT MAINLY JUST SOME LIGHT SNOW ACROSS NORTHERN MA THROUGH EARLY AFTERNOON. ACROSS THE REST OF THE REGION…MAINLY DRY WEATHER WILL PERSIST INTO EARLY AFTERNOON WITH JUST A FEW FLURRIES/LIGHT SNOW SHOWERS POSSIBLE.

    SNOW WILL BEGIN TO FILL BACK IN ACROSS THE REGION BY MID TO LATE
    AFTERNOON. THIS A RESULT OF A STRENGTHENING EAST TO NORTHEAST LOW LEVEL JET AS WAVE OF LOW PRESSURE APPROACHES FROM THE WEST. WE ALSO WILL START TO SEE LOCALIZED HEAVIER SNOW BANDS SETUP NEAR THE I-95 CORRIDOR BY EARLY EVENING ON A STRONG COASTAL FRONT. IN FACT…BOUNDARY ALREADY SETTING UP WITH TEMPS RANGING FROM 18 DEGREES IN LAWRENCE AND 34 DEGREES IN MARSHFIELD. THERE IS THE POTENTIAL FOR OTHER LOCALIZED HEAVIER SNOW BANDS ACROSS THE WORCESTER HILLS AND EAST SLOPES OF THE BERKS…AS A RESULT OF SUBTLE UPSLOPE FLOW. IN BETWEEN THE HEAVIER BANDS OF SNOW AND ESPECIALLY IN THE LOWER CT RIVER VALLEY WITH SOME SHADOWING…EXPECT POCKETS OF
    LOWER AMOUNTS.

  117. Perhaps the last Hurrah with this band, but snowing really good here now.
    Radar display indicates that it should quit very soon.

  121. Today is good day to do any additional cleanup needed and get rid of any more snow on the roof, etc. any more snow and then rain is going to start making things dangerous. I am off to spend a couple of hours outside. Going over to Charlie’s for a pool party around 2 🙂
