Hi everybody! Sorry for the short discussion & forecast following this. Bigger update later today… Leaning toward more of a miss than a hit for Saturday at this point. Some lighter snow during the day. Bigger punch of precip. stays offshore at night (if it comes further west we’ll have much more snow but leaning away from this at the moment).
TODAY: Partly sunny. Highs around 50. Wind S 5-15 MPH.
TONIGHT: Partly cloudy. Lows 25-30. Wind W to NW 5-15 MPH.
SATURDAY: Cloudy. Periods of snow and rain with up to a couple inches accumulation of snow mainly away from the coast. Highs 33-38. Wind NW to N 10-15 MPH.
SUNDAY: Partly cloudy and windy. Low 18. High 28.
MONDAY β PRESIDENTS DAY: Mostly sunny. Low 14. High 34.
TUESDAY: Partly sunny. PM rain showers. Low 29. High 44.
WEDNESDAY: Variably cloudy. AM snow showers. Low 28. High 38.
THURSDAY: Mostly sunny. Low 18. High 33.
Thank you TK. Good news IMHO for those still dealing with the aftermath of last weeks storm
Agreed Vicki…glad for new blog as comments were slowing my phone down.
Thanks TK. Good Morning All! One thingβs for certain; it sure is a beautiful sunny February morning! With models all over the place, it should be an interesting day on the blog π
Thanks TK
CMC still shows a big hit. Who knows if that upgrade is on to something.

I am going to take the dog for an extra walk or two today, A+ weather.
In regards to the storm, from my perspective it is a win/win. I love snow and would enjoy more, but I could also use a break from the blizzard’s impact – the only losing scenario would be wet.
Good morning everyone π
Hi Emily – you don’t have a break this coming week correct? Yours is in March??
Eastern New England will be the area that has the POTENTIAL to see any snow from this coastal low pressure system.
I am thinking a light snowfall for those areas 4 inches and under. With that said any shift in track could make a huge difference.
Yet ANOTHER new map on Channel 7…the 4th one I think…
http://www1.whdh.com/images/weather/producer_uploads/special-560×389.jpg?02150750
that map makes absolutely no sense – what are they seeing that I am not? Best chance for accumulating snow looks to be eastern areas.

With such a negative tilt on the NAM I am surprised it does not come up the coast.
Boy it’s close on the NAM, just misses. But it’a huge storm, slight jog west and boy we would be talking about a monster. Just doesn’t look like it’s in the cards.
I will be very interested to see what the GFS and CMC show. This would not take much to come right up the coast.
Curious why no one is talking about the Euro anymore? Seems like reliance on models we rarely touch on like the CMC…
I am also waiting on the EURO as well, trust me
WW less looking at the EURO bc it has not shown it to be that big so I am more looking for a continued trend from the CMC and GFS. EURO is probably the way to go
Ah OK thanks.
12Z NAM has a MOOSE of a storm. “Just a bit Outside”
BUT it looks closer than on the previous runs. IF those upper winds
buckle just a bit…. All bets are off.
Now we’re waiting as there is nothing else to look at.
Back to work.
π
As I always say when ever there is low pressure on the east coast it needs to be watched. A slight shift west could make a big difference.
I still don’t feel as though the models have a good handle on this yet. Just from yesterday the models went from the intial piece of energy on saturday being the primary piece of energy to that being a minor event and a secondary piece and stronger developing after that and that’s still 36+ hours, so we’ll see. I do trust the NAM in general(in this time frame) and it’s not very robust as compared to some of these other models.
Thanks TK. Hope everyone gets to enjoy a long weekend. I know I am looking forward to having a few days off. Wouldn’t mind not having any snow this weekend so let’s hope it stays out over the fish!
Not loving the overall euro run. Lots of storms but they’re all progressive.
Meaning fast moving?
Progressive does mean fast moving. With that said you could still get a good dump of snow with a progressive
system as was the case back on December 29th when some places came in with close to a foot of snow across parts
of SNE.
nogaps is your model for surprise storm this weekend.
I’m OTS on this weekend with nothing really west of 495
Still looks like a beast in the making for the long range
http://raleighwx.americanwx.com/models/euro/00zeuro850mbTSLPUS240.gif
Flow too fast. Euro paints 0 snow after this weekend through the whole run to 240. Everything zips right through the flow and OTS.
Mid Atlantic adds snowcover.
Yeah, but just yesterday someone alluded to the Euro putting down 24-30 inches north of Rt. 2 so I would take that with a grain of salt, either way.
Over the full run I believe yesterdays 12Z, may be mistaken though
yeah, that was me.
not saying this stuff is etched, just providing long-range updates.
pattern is loaded but we’ll need some digging troughs.
it’s really all Pacific flow.
agreed
It sure looks that way Retrac, but surprises are always there π
I’m guessing based on TK’s hints he is going EURO?
The 12z Nam has moved the storm closer then the 0Z Nam.

β** ALERT IS THERE A SURPRISE NORFOLK to BOSTON SNOWSTORM COMING THIS WEEKEND ? ***
The term NORFLK to BOSTON snowstorm is one of those phrases that old timers use and one that was popularized by the late great weather historian David Ludlum. The last really clear-cut example of a NORFOLK to BOSTON snowstorm but I can think of off hand was the November 1987 surprise that VETERANS DAY snowstorm. That snowstorm which was poorly forecasted by most… dropped significant snow over Eastern Virginia and Washington, DC as many residents can recall and across far Eastern Long Island southeastern Massachusetts in Boston but for New York City Philly and N NJ… very little snow fell.
Wxrisk.com
This first image shows the Canadian model from last night. Now remember the Canadian model has had a significant upgrade and it’s probably pretty good with the shore range. We can clearly show what the Canadian is trying to do as it forms the Coastal low much closer to the coast.
http://mysite.verizon.net/vze1aqbof/sitebuildercontent/sitebuilderpictures/0zggem.gif
In this next image we see the 6z GFS trying to do the same sort of thing– notice again how the precipitation shield appears to be centered mostly over Eastern Virginia through the Delmarva.. Across far Southern New Jersey and then over the eastern tip of Long Island… Rhode Island and Southeastern Mass .
http://mysite.verizon.net/vze1aqbof/sitebuildercontent/sitebuilderpictures/6z.gif
And finally here is a comparison of the precipitation shield total for the next 72 hours. Now this is in liquid rainfall amounts but still you can see clearly what these models are trying to indicate. Assuming that the low does in fact develop this close to the coast…. It is possible that the significant precipitation — SNOW — MIGHT just reach into eastern NJ NYC and western CT… and northwest PA and interior southeastern New York would miss the Moderate or significant snow.
http://mysite.verizon.net/vze1aqbof/sitebuildercontent/sitebuilderpictures/orfbos.jpg
Did someone mention NOGAPS? Here is the 0Z run:
http://raleighwx.americanwx.com/models/nogaps/00znogaps850mbTSLPp06066.gif
This is a real tricky forecast for sure, I remember two years ago a similar set up with the NAM showing a storm just east of us and then bam 1 foot later we were digging out bc the storm moved closer. The negative tilt on the NAM would concern most mets.
Thats good point to bring up about a slight shift making a huge difference. This is too close for comfort.
12Z GFS = foot+

Regular CMC is complete to 48 hours. Global that goes to 240 hours is not complete yet.
Beat me to it Hadi, GFS is closer. Can’t wait to see the other 12zs
CMC looks like it backed off some, still moderate snow. Waiting for cycle to finish
I thought the Canadian 12Z doesn’t run until 12:15?
Much earlier now since the upgrade

http://collaboration.cmc.ec.gc.ca/cmc/cmdn/pcpn_type/pcpn_type_gem_reg.html
definately backed off, do you know what kind of QPF that is spitting out?
I would except Winter Storm Warning to be posted as the HPC has been using a blend of GFS.
Is this thing really gonna happen???
Not sure but they have been going with a blend of GFS/CMC and EURO
Ahh hadi is that link u posted showing 2 feet of snoww???? Or is that the total snow that is going to be on the groundd? Lol am just confused. And one hting i noticed is that the NWS is saying we r gna have mixing issues sat eith a high of. 39 degrees? I didnt hear anything anything like that here
Kane i re-checked and it’s snowfall…odd
Looks like u used cm instead of in
The meteorologists must be pulling there hair out. Huge bust potential either way here.
I am hoping the low tracks a little further west. Right now the GFS is showing 3 inches for western CT.
opps I posted snow depth π
No i posted it in CM, LOL
π
GFS has it coming in two pieces huh?
Huge bust potential retrac for sure
At this point I’d love some agreement so I can plan tomorrow…have a few functions and have no idea what to do. One run say 30 inches…another a few…and we are under 24 hours. Makes me wonder how they did this before computers told them what to do. π
Still shows 12+ inches for eastern sections
If that was a 6Z or 18Z run it would be easier to ignore. I dont expect much change with the euro. Its not known to make huge swings in the short range, and going from what it showed in the 0z run to what the GFS is showing would be a huge swing. NAM and other short term reliable models is the way to go at this point IMO.
What a brutal forecast to try and make. We’re not talking about a simple R/S line here. This is sunny day versus winter storm warning.

GFS 12z really bombs out the coastal low. 1000 mb to 956 mb in 24hrs, getting into the historical territory. pic.twitter.com/bEdARnMR
Retweeted by Tim Kelley NECN
They have to hoist a WS watch based on that 12Z GFS run imho
I think they may want to wait on more guidance to roll in before pulling the trigger… maybe the 12Z Euro or the next NAM output.
NWS Upton discussion issued at 10:49AM is interesting, expecting a Nor’Easter for this weekend, considering watches in SE CT albeit with limited confidence in the forecast:
http://forecast.weather.gov/product.php?site=NWS&issuedby=OKX&product=AFD&format=CI&version=1&glossary=0&highlight=off
This HWO in CT kind of says it all:

http://boston.cbslocal.com/2013/02/15/expect-snow-this-weekend-but-not-a-major-storm/
So this is BZ’s take with the 2 stage rocket that retrac was referring to w/the GFS?
Captain I agree, but as the HPC has been leaning with a GFS blend I am guessing it will be issued either way .
One thing is for certain this weekend regardless…Atlantic Canada is going to get slammed with a blizzard.
Presque Isle, Me. – waxed.
If there is going to be warning criteria with this storm and BIG IF it would be eastern parts of SNE. I could see advisory level snowfall reached for western areas SHOULD the 12z GFS pan out.
A slight shift east lower amounts. A slight shift west potential for higher snowfall amounts.
WBZ’s forecast looks very reasonable and responsible.
I agree with you on that!
Soooo 1-8″…lol
Nobody is going to be in a rush to put up watches imho. 9z SREF snow probabilities are barely over 50% and we still have the King to bow to.
IMHO the trough will go negative sooner, thus a bigger storm. I have read several mets discussing this and I posted that this morning. I really think the models are not handling this well. But hey what the heck do I know π
Well, there is a pretty strong jet at the base of that trough, 160 knots in Florida and it does go negative but not till it passes us. We’ll see.
This is what I love about this!!!
Tim Kelley tweeted to the NWS and below is their response…we bow to you king
“Given the large spread in 12 models waiting to see the 12 EC trends before making any decisions, Ur thoughts on event”
Its just alarming to me that this thing will be tomorrow and we have no clue what the weather will be 8)
no doubt glad we are not issuing a forecast π TK is probably stressing!!
TK is as cool as a cucumber.
π
First piece of energy tomorrow, main/larger piece is more like Sunday
CMC really doesn’t show much either, a general 2-4 or 3-6 for most of eastern mass.
More than the euro has been showing. Most models seem to be showing at least something, in the light to maybe moderate range. Euro is and will be the outlier.

Regular CMC is complete to 48 hours. Global that goes to 240 hours is not complete yet.
If only we had high pressure above us, it’d be a repeat from last weekend
Geez looking at models we could get anywhere between 1 inch and a foot, I can’t buy the foot, it doesn’t look right, it seems progressive to me, will c π
Did anyone hear about all the damage done to cars from parking wars, I don’t know why they don’t just remove the snow in city? I guess a few cars r totaled, crazy
I don’t understand why people get so crazy with parking when it snows. It should work the same way it does when there’s no snow. When you leave the spot, it’s no longer yours. Yeah it sucks you spent two hours shoveling it out, but you chose to live there. I just don’t get it
I agree
130pm…. What they are really saying is we want to see what cards are in the King’s hand first! A tweet 5-10 minutes ago from NWS Boston:
@NWSBoston: Conflicting signals in new data for this wknd’s forecast. Hence big bust potential! Still reviewing data. More details by 130 pm. #SNEwx
We all wait on his highness to speak!!!
Betting on the hot hand is always smart.
I pay for a garage in the city to avoid the craziness. Totally worth it.
Oops – that was supposed to be on the thread above – sorry!
Got it DS. I was wondering..
What analog do you all think this represents ? I think the BDB 2011.
I was wondering that yesterday. We need the O.S. crack research team on that one.
Bernie Rayno thinks it’s going to go negative sooner
This is eerily similar to BDB
Whats BDB?
Boxing Day blizzard. Not saying same type of storm but rather the model situation.
Ahh, gotcha
Tweet from Tim Kelley
@SurfSkiWxMan: @NWSBoston So warm now, such rapid cool’g aloft tomorrow. Trough tries to go Neg. Natural Baroclinic off ACK. winter storm watch E MA to ME?
Tweet from NWS to terry at bz. Lol
@NWSBoston: @terrywbz Hi Terry, not necessarily confused just recognizing it’s a pattern w/low predictability given the complex trof merger/interaction.
Todd’s calling it straight:
@ToddWBZ: Funny how quiet the weekend storm chatter is…everyone waiting for EURO!
That’s right…
so what is it…. what’s everyone’s take on euro
I think Euro is going to hold serve and put down 6″ along 95 from Boston through providence with 2-4 Worcester.
Hope it’s more but….I don’t know.
I do want to see 12z nogaps for kicks as it has been fairly consistent with heavier precip. Should be out by about 1:30 or so.
I am thinking the EURO will come in with a much different solution than the GFS. All waiting with anticipation on the run of a computer model.
I think the euro sticks to its guns.
I just hope we get something locked in. Curious about all the “bust potential” tweets…
BTW the euro from the 00z run did show 4-8 from Boston south
I think 4-6 is where we will land in the Boston area.
decent storm, DS π
Totally! And certainly all I can handle at the moment! Ever tried to walk a newly spayed puppy with stitches in a foot of snow? NOT AWESOME.
what kind of puppy
poor dog π
Golden retriever. I actually have two – one is a year, the other is six months. They’re incredible.
I have a 6 year old Golden!! The most wonderful dog you could own!!
I can’t believe we ever lived without them!
sort of like a cairn terrier at any age – he took one look out the door last Saturday morning and just turned and looked woefully up at us. I do love goldens!
EURO is starting
wow this will be a serious next 24 hours to see what happens. will the king fall ill or will the king be right after all. i have coral reefe ecology from 145-4 so i will not be able to look until tonight. but this is one of the most difficult forcasts i have seen. right now i think a light snow event is very possible.
saturdays small event will dump a few inches across the region even some light rain to start inside of 495 and east of i95. where i am looking is saturday night through sunday. huge bust forcast either way. I bet some of the tv mets are gonna get bashed by the trolls

β*** 12z EURO iNCRESES THE PRECIP OVER EASTERN THIRD OF NC AND VA… Mostly east of I-95 to the BAY and coast . SURFACE temps away from the coast appear to be cold enough for snow.. something like 1-3 ” maybe 2 -4″… areas such as
RALEIGH EMPORIA ROANOKE RAPIDS ROCKY MT GOLDSBORO
TRI CITIES… WILLIAMSBURG SUFFOK FRANKLIN GLOUCESTER eastern portions of Northern NECK SALISBURY OCEAN CITY POCOMOKE
all this misses DCA PHL NYC N NJ ..according to the the 12z EURO
What does this translate to for MA?
Some snow like the 3-6 inch range but nothing like the GFS
Looks wide right to me at 48 hours, anyone else see anything different?
No.
Light and some eastern areas with moderate storm.
Agree Captain, so it’s GFS vs. the rest… I will take the field and stick with my 3-6 inch call from yesterday.

@neweathereye.did glance at Euro,I don’t see anything on that to discount GFS & more importantly,current Sat supports quicker – tilt of trof
JR posted a map on WHDH for 3-6 eastern areas
Stations all have their maps
WB ranges from 2-4 inside 495 to 1-2 past 495
WHDH has 3-6 about to CT river then 1-3 on cape and past CT river
WCVB has 3-6 inside 495ish and 2-4 past there
Seems BZ is the most conservative and the cape is are most up in the air??
That was supposed to say the cape and west of worcester is area most up in the air – or so it appears to me.
Man I’ve never seen WHDH change their weather maps so many times…yet another one post a few hours ago. Maybe they should wait a bit.
Actually, Reiner just tweeted an updated one, but it’s not on the site yet: http://twitpic.com/c40voh
It’s on the site – I think that’s what I just posted above.
nope – you are right – it isn’t on the site – they changed the cape amount
WHDH is the weather carnival sometimes: spin the weather map wheel, where it will land, nobody knows
In fairness, brutal forecast to sort out, but they are not helping the situation.
Last they had me in the 1-2…then 4-8…now 3-6…granted not huge jumps either way…
They have a knack for putting me right on the boundary between zones. π
I was at a meeting this morning and nearly everyone was saying that they were glad to know something is coming even though the stations appear to be unsure of the amounts. IMHO The majority of the public is not only smart enough to get that it changes but also appreciates knowing ahead and seems to actually be getting into the explanations of the models and how they differ. I was surprised how many who really have no interest in meteorology were using the term EURO.
Bingo, if the EURO was trading on the NYSE, you would want to sell it right about know. It is all over Main St.
It really is Captain and every one of them seemed pleased they knew about it. I give credit to our mets on every station – way back to Sandy – when they started actually letting the public see how difficult it can be.
Net/Net – Winter Weather Advisory posted later tonight or tomorrow morning?
Sticking to my guns and not getting lost in the translation of the various model solutions. This particular set up is very difficult to produce significant snow. Eastern MA still needs to watch closely but still calling for a minor event at this time.
I am reading the Canadian run may have had feedback issues and initialized too far away from the coast. Not sure if there is any validity to that. If so, the GFS may not be alone in its stronger/closer solution.
Regardless, it is still hard to discount the consistency of the mighty Euro.
Bernie Rayno β@AccuRayno
@neweathereye.did glance at Euro,I don’t see anything on that to discount GFS & more importantly,current Sat supports quicker – tilt of trof
The key is the front coming in just does not capture it, if it did boy we would be talking.
The Euro must be respected. Am I correct in the fact that each successive run in the Euor the QPF has gotten Slightly and I mean Slightly hihger…I remember Hadi posting .22 and then something like .28…I’ll take a few inches to cover up the ugly old snow
I don’t have a ton of time today.
All this such a tough forecast talk has nothing to do with trof merger’s, best deformations zones and all the other stuff I am seeing thrown around is kind of funny. It is simple, tt is confusing because the models are all over the place and no one wants to forecast anymore without a model consensus.
The GFS that everyone laughed at last week is now awesome because it is giving some people the solution they want to see. It is confused and that can be found my looking at its MOS output. It’s POPs don’t reflect the kind certainty that it would show if it was locked onto a foot of snow type solution and its own snow tool output is well below its corresponding graphical output. Bottom line I think it is lost at the moment.
Very simply the best barcloncic zone clearly sets up South and East of Nantucket. Pressure drops to 1000 at Boston, but not much lower. That means no big storm.
Generally two waves overnight tonight and then again mid-day on into early Sunday AM. Daylight snow is going to have a tough time sticking on roads because of time of year and how light it will be falling. Looking at a generally 1-2″ North and West, 2-4″ Mass Pike South and East of of the 495 interchange.
I bet if TK was here, he’d agree with you. Thanks JMA! Good stuff and makes me feel better…good line: “The GFS that everyone laughed at last week is now awesome because it is giving some people the solution they want to see. “
What does MOS output and POP stand for?
NWS and local mets can’t just discount the GFS, they could be burned. Also keep in mind EURO is not prefect either. It nailed the blizzard and Sandy but was not great in between.
As always thanks JMA!! keeping it real!
Even if the EC latched onto a closer/stronger solution, I still feel there would be way too much bust potential in this particular set up.
Re-post clearer first paragraph.

I said 3-6 yesterday and not going to waiver, would love a big one again!! Just not in cards this go around.
I have to agree with the JMA and TK models on this one.
NS is going to get slammed by this, down to near 960
A quick review/summary of the NWS – Taunton/Albany/Upton discussion issued within the last 30-45 minutes:
Taunton – 4″-6″ in E SNE
Albany – 1″-3″ in Berks
Upton – 6″ or so in eastern edge of reporting area (CT/LI)
Upton is sticking w/HWO, not watch for 4PM, but may change as more data comes in and they coordinate w/HPC.
MOS = Model Output Statistics
POP = Probability of Precipitation

Weather for DC protest Sunday 36 degrees nw wind 15-G 25 about 10 below normal. Latest AGW blizzard should be ending in Boston
I don’t think we see a blizzard in Boston or anywhere in SNE. I think a light to possibly moderate snowfall is POSSIBLE.
I think that guy is whacked.
I watched his video for this storm, wow, commercial forecasting – has Boston in a 24″ swath. Who pays for that type of forecast and how are they using it? He is apparently amplifying the GFS, would love to see it verify, but it defies logic.
Watch the first few minutes of this video: http://www.weatherbell.com/saturday-summary-february-9-2013
OUCH, it is over a week old, just caught the date. Well at least he nailed that one.
Upton NWS not backing down

Good lord. Watching TWC is a lot like watching Fox News. Crazy #*%#*^ nuts.
Why is that?
Hype, spin, and ridiculous personalities.
hahahaha – I agree
I gave up on them 5+ years ago; love Cantore on the scene stuff, but I can pick that up from his twitter feed.
Is anyone else a little nervous about the asteroid making its closest pass to earth in a half hour? 17,000 something miles? In space measurements, that’s close man!
I read that if the arrival was 15 minutes sooner or later (can’t remember which), it would have been a direct hit. Good times.
wow – in asteroid terms that is a very small margin – 15 minutes that is. I read it will not be visible to the naked eye and not even with a telescope in north america – it’s due to pass at 2:24 ET and 17,500 miles above earth’s surface. The one that hit in Russia injured a lot of people last I heard.
They claim the 2 werent connected and that it was just a coincidence. I think not, lol
You know what – I don’t believe in coincidences so I am very inclined to agree with you Ace.
Not nervous, interested though
I guess I wouldnt think twice about it if the meteor hadnt exploded over russia this morning
DT on Boston
Wxrisk.com gets hit HIT not a much as on the 12z GFS/ CMC
Who is DT?
Now watch the NAM come in stonger, lol
lol, wouldnt that be something! The NAM and other short range models are the ones to watch now. GFS and EURO and other medium to long range will be less important from here on out.
SREF, ARRW, NAM and RUC
I really had high hopes for the 3 week period following the blizzard in this very active pattern. However, our first storm missed on Thursday, this weekend looks like a miss or sideswipe (depending where you are) and now the NAO and blocking looks to get so strong that the storm late next week looks to get harmlessly shunted south of us (both GFS and Euro show this). That one’s still a week off and much can change, but right now, not looking too good.
I hear ya Mark, hang in there through next week and we shall see what happens.

So what gives. HOW does this happen?
This baby is MUCH closer than its previous runs!
π π π
That’s why it is still an “experimental” model. It’s only company right now is the NOGAPS. Enough said π
HPC now going with a blend of CMC and EURO
PREFERENCE: A BLEND OF THE 12Z ECMWF/12Z CANADIAN GLOBAL
CONFIDENCE: SLIGHTLY BELOW AVERAGE
What does that mean in terms of QPF in/around Boston?
OS I saw that as well, interestingly it was very good with the blizzard.
Hadi,
I’ve been watching that for the past few weeks. If I am not mistaken,
it has been very good.
Look at the digging with the trough, what a waste of a powerhouse storm.

EURO snowfall
http://forums.accuweather.com/index.php?act=attach&type=post&id=191668
Thanks for posting. So 3-6, eh?
What does the Euro bottom this storm out at in millibars?
Does not look that impressive for the portions of Canada on this map either.
In other words, does it wind up the storm just off-shore, but does not agree with the strength some of the other models had? Given all the chatter, I thought it was too east or late developing for more than moderate snows in New England, but Canada was supposed to get pasted?
I will be in VT so I doubt I see much there except upslope snow showers.
I would guess 3-6 might be generous, just remember there is always a chance of surprised.
18Z NAM, Just a bit too far off shore, however, CLOSER than 12Z run.
Here is 18Z snow map, which is similar to the 12Z run:
http://www.instantweathermaps.com/NAM-php/showmap-conussfc.php?run=2013021518&time=PER&var=ASNOWI&hour=048
For comparison, here is 12Z snow map:
http://www.instantweathermaps.com/NAM-php/showmap-conussfc.php?run=2013021512&time=PER&var=ASNOWI&hour=072
Well now, after looking at them together here, 18Z NAM is more snow.
Not by a whole bunch, but more none-the-less.
A trend? Probably meaningless. We’ll see.
Afternoon all!
I’m feeling coating to inch or so for part 1 Saturday morning and 2-5 inches for part 2 Saturday night and early Sunday.
Something is not right with the GFS and I can’t pin down what it is. But one thing it’s doing is over-strengthening lows and making them too symmetrical. It reminds me of a basic barotropic model with not enough grid points. So early 1980s…………..
HA. On the 2-5…I assume where we are we are at the higher end or no?
For Woburn I guessed 3.8 …
Cool, thanks. I don’t care if we get snow so much as long as it’s below the “I have to roof rake” criteria. Guessing this is.
I believe it will be.
Part 1 will be a wet snow.
Part 2 will become a very dry and light snow.
Captain it bottoms out in low 950!!
http://raleighwx.americanwx.com/models/euro/12zeuro850mbTSLPUS120.gif
Ok – that is a tightly wound storm!
Um, that looks like 998 to me. π
read in the top corner, put on those reading glasses OS π
95X
what are you viewing? the map I am viewing has no 950MB on it. Let me go directly to the site. I have
trouble with that site as it sometimes links OLDER maps.
Be back soon.
Yes, that was the problem. This one clearly shows 959!
http://raleighwx.americanwx.com/models/euro/12zeuro850mbTSLPUS072.gif
I was just teasing with the glasses thing π BTW
So parts of Maine are under a blizzard watch, that last Euro link shared does not look like a blizzard to me for down east Maine, is it b/c it is only through 60 hours or b/c the Euro is not locked in on it yet?
Blizzard watch and WSW for parts of Maine, does not make sense to me
Today did it for me, spring fever has hit, its absolutely beautiful outside. Can go out in the sun without a jacket.
I want more of today, lots more !!
I am going for a jog, my hope is our storm does the same thing – just 50x further to the west.
Boo! π
π
Preach on!
Looking at NAM/CMC and EURO no way do any of them warrant a WSW let alone a Blizzard watch?
Bingo – so what do they see? I suppose the wind criteria may get there of this drops to 950 mb. Don’t need a lot of snow if the winds are there… the mid-west gets ground blizzards if the conditions are ideal w/o precip.
Yeah but 950 is not until it’s past Canada, still not sense and the WSW posted says 6+ inches
Tom don’t get used to it π
Unfortunately, I agree. However, it looks like in the extended, it will be chilly, but dry. Starting to see the supressed solutions for the storms in the long range. Probably when we look back at the winter as a whole in late April, NEMO will stick out as a huge anomaly in an otherwise very dry pattern.
The Blizzard Watch may very well be warranted given the trajectory of the wind field associated with the low pressure system. It explodes into a beast as it passes. Downeast Maine catches it, along with very cold air so that any fallen/falling snow is easily blown.
I would not buy into such suppressed solutions.
15Z SREF shows some fairly good snow 12 hour snowfalls. Here’s a sample:

What aren’t they smoking in Brockton?
….Kidding! Love that town.
WSW on the coast!

WSW posted for coastal areas of SNE.
How do you type screaming ? π
ARGHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH
It’s the same thing I do in my head when the wife says “I’ve been thinking…” π
Now that really made me laugh !!!!
Another favorite is when she says “We can start painting the rooms…” I’ve been married long enough to know you take the W in We and turn it upside down…so We = Me. π
So true, so true.
LOL !! Thanks, I’ll remember that.
This is just what Marshfield needs, a few to several inches of probably wet snow and fairly windy conditions. Lovely !! Can I still find a flight somewhere warm for the real February vacation ?
You can say that again
Come up to VT with me π
I heard they have some cheap cruise deals on the Carnival Triumph right now. π
Thanks a lot Hadi and oh yes, that cruise sounded like a lifetime of post traumatic stress issues for those passengers.
LOL I bet
The snow emergency starts tomorrow at 4pm. Im sure they declared it in order to enforce a parking ban so they can plow the streets. Thats what they do here in Lynn.
DT has Boston south in the 6″ Range
Who is DT again?
Take a look for him at this site or on facebook.
wxrisk.com
This has a HUGE and I mean HUGE bust potential
Bust as in less or bust as in more?
Both!
Bust as in now snow? I disagree, 3 to 6 and get nothing isn’t bad. Especially how the mets have communicated the difficulty with this system. If it was 18″ and we got nothing then that’s a different story. There is no such thing as a bust when you are not expecting snow and you get 6″= π
I hope so. Sick of snow. Sick of driving in it. Sick of shoveling it. Craving spring.
I’m torn right now Lisa. Love snow but today was a big teaser.
Lets have a storm in the middle of the week for a change! :-).
How can there be a winter storm watch thats immediately bounded to its west by……. nothing, especially when the snow forecast does not have a sharp snow gradient. West of the watch, the vast majority of the area is under 2-4. Doesnt that require either a special statement or a winter weather advisory. Also, I did not see one station in SE Mass for a 100% guarantee of 1 inch of snow.
Its to educate the public of the potential. Things will change tomorrow.
Somebody who was suppose to get snow is not and who was supposed to not get snow will get slammed
I hope the jackpot is in Wrentham and leaves us on the coast alone. π
LOL
Hahaha π
sref ensembles look pretty good SE Mass.
That is interesting Retrac bc I believe it might be a trend. Bust potential either way.
50% probability of .25 or greater QPF now up to about S.S. versus the canal earlier
Here comes Da Judge, Err I mean here comes the GFS. π
exactly O.S.
Interesting from Grey in Maine, again I question this as EURO paints 3-6 inches in Central Maine, the watch says 6+.
WE ARE MAINLY GOING
WITH THE EURO OVERALL FOR POSITION.
Todd Gutner β@ToddWBZ
The Sunday AM coastal storm will blow up offshore with an expanding wind and snow field…amounts could easily go up for the Coast.
Come back NStar, dont leave Marshfield just yet !! At least next week cant take away more beautiful June days.
Or your April vacation which if some schools miss 1 more day they will have no vaca
So, is the disturbance in question the twist in the clouds I see over Nebraska diving towards the SE, headed for rounding the base of the deepening trof ?
GFS bows to the King
GFS has cut way down on precip….Blah .50 liquid precip
I love it when the GFS comes around to the Euro. The GFS is nothing more than the jester to the KING.
However, it’s the 18Z run. With this delicate situation, that is probably ample reason NOT to trust it in any way. With this situation NEED each and every data point! π
I would not be surprised to see it closer to the coast with the 0Z
run.
The mets must be going NUTS!!!!
Can you imagine if they called for 12″ Plus this morning only to have to take it back this evening. Wow!! It pays to be cautious.
We’ll see what happens.
Certainly leaning to not much in the way of a snowfall. π
I know it’s onl the 18Z run, but the 18Z GFS has taken a right turn.
VERY powerful storm, but WAY off shore!

I don’t know how anyone could go with this piece of S***T!!!!!
All hail the king!!
Hey,
The King’s S**t smells just like the rest of us! π
Looks like the Canadian upgrade was a failure too..
What about those initialization issues? Let’s see what the 0Z run is like. π
“initialization” issues, is that like wizard of oz stuff
π I don’t know. Someone mentioned it. Don’t know if real or not.
But in my business, we have an old saying about data.
“Garbage in, Garbage out” π
Or as Tk once said, if the model doesn’t know what it is doing now, how is it going to predict what it will be doing in 48 hours????
π π
0z GFS, 18z, 6z….who cares. Something smelly to O.S.’ point smells at all times of day.
I’ve tossed the models and I’m just forecasting old school style. Update soon!
Awesome.
So are you still with the 2-5 inches?? π
2-5 W, 5-9 E .. for now
I can’t just go based on models, have to look at the arctic front and see what happens. It can cause explosive development.
Hot off the NWS press
FORECAST CONFIDENCE IS LOW GIVEN SIGNIFICANT MODELS SPREAD. THE
MODELS ARE IN GOOD AGREEMENT IN LOW PRESSURE BOMBING OUT AS IT LIFTS
NORTHEAST AND PASSES SOUTHEAST OF THE BENCHMARK SAT NIGHT INTO SUN.
THE MAIN ISSUE THAT NEEDS TO BE DETERMINED IS HOW QUICKLY THIS
OCCURS AND WHERE IT HAPPENS. THE GFS MODELS IS THE MOST AGGRESSIVE
IN QUICKLY BOMBING THE LOW PRESSURE SYSTEM CLOSES TO THE COAST.
THIS RESULTS IN THE COLD CONVEYER BELT SLAMMING EASTERN NEW ENGLAND
WITH HEAVY SNOW LATE SATURDAY NIGHT INTO SUNDAY. WHILE IT DOES HAVE
SUPPORT FROM MANY GFS ENSEMBLE MEMBERS…THE REST OF THE MODEL SUITE
HAS A TRACK FURTHER EAST.
ALL IN ALL…GIVEN MOST OF THE MODELS WERE NOT AS AGGRESSIVE AS THE
GFS TOOK THE MORE CONSERVATIVE APPROACH IN THE SNOWFALL FORECAST.
FEEL THE BEST ACCUMULATIONS FOR MOST OF THE REGION WILL BE 1 TO 4
INCHES WITH THE HIGHER AMOUNTS AS ONE WORKS EAST TOWARDS THE COAST.
WE DO THINK THERE IS A DECENT POTENTIAL FOR HIGHER AMOUNTS AND/OR
STRONG WINDS/VERY POOR VISIBILITIES ACROSS THE FAR SOUTHEAST NEW
ENGLAND COAST. DEPENDING ON HOW CLOSE TO THE COAST THE STORM
TRACKS…THERE IS THE POTENTIAL FOR 4 TO 8 INCHES OF SNOW IN THIS
REGION. IN ADDITION…A RAPIDLY DEEPENING LOW PRESSURE SYSTEM WILL
LIKELY BRING STRONG WINDS LATE SATURDAY NIGHT INTO SUNDAY TO THIS
REGION. EVEN IF SNOWFALL AMOUNTS TECHNICALLY FALLS BELOW
CRITERIA…ITS POSSIBLE THAT THERE IS A PERIOD OF NEAR WHITEOUT
CONDITIONS FOR A TIME LATE SAT NIGHT INTO EARLY SUN AFTERNOON.
ALSO…THE SNOW WILL INITIALLY BE WET IN THIS REGION SO THE
POTENTIAL EXISTS FOR A FEW DOWNED TREE LIMBS/POWER OUTAGES WHEN
COMBINED WITH THE STRONG WINDS. WE FELT ALL THESE CONDITIONS
WARRANTED A WINTER STORM WATCH FROM EASTERN PLYMOUTH COUNTY/CAPE COD
AND THE OUTER ISLANDS. THE SNOW SHOULD TAPER OFF FROM WEST TO EAST
BY EARLY SUN AFTERNOON…ALTHOUGH IT COULD LINGER ACROSS THE
CAPE/NANTUCKET A BIT LONGER WITH SOME OCEAN ENHANCEMENT.
AGAIN…CONFIDENCE IS LOW BECAUSE OF THE UNCERTAINTY HOW QUICKLY THE
LOW PRESSURE SYSTEM WILL BOMB OUT. WILL HAVE TO SEE HOW THE MODELS
TREND OVER THE NEXT 12 TO 24 HOURS. IF THE STORM TRENDS FURTHER
WEST AND BOMBS OUT EARLIER THAN THE CURRENT FORECAST
INDICATES…LATER SHIFTS WILL NEED TO EXPAND WINTER STORM WATCHES
AND POSSIBLE WARNINGS FURTHER EAST. IF THE TREND IS FURTHER
EAST…MUCH OF THE REGION WILL JUST BE LEFT WITH AN INCH OR TWO.
maybe I’ll have to drive to Chatham!
Well, that about sums it up, doesn’t it? Nice write up for a change.
π
Alrighty. We’re updated…
