2:39AM
We remain near the boundary between very cold air to the north and west and milder air to the south and east, and that means some unsettled weather today with snow/ice/rain. This system is expected to behave as described in the last blog entry, with a light amount of snow to start the day today, except mix/rain closer to the South Coast and Cape Cod, with the rain area advancing northward to include all of the region by early afternoon. Cold air at the surface means some icing will take place over interior MA and NH for several hours during the morning and midday, with some hazardous travel on untreated surfaces. This system winds down later today and is gone tonight, with lingering clouds and some fog around. As expected, its trailing cold front will linger just offshore and allow a wave of low pressure to move up along it Tuesday, bringing a good chance of a period of mix/snow to RI, eastern MA, and coastal NH, though this should be moving along rather quickly and snow amounts will be limited. Drier and cold weather will dominate from the middle of the week to the start of the weekend, with a few minor disturbances bringing occasional clouds and a slight chance of snow showers. A trough moving into the region at some point over the weekend may increase the chance of some snow, though early indications are that this would not be a big storm.
Forecast for southeastern New England (southern NH, eastern MA, RI)…
TODAY: Overcast. Areas of snow, except mix/rain southeastern MA and southern RI, changing to rain south to north, with a period of icing interior MA/NH through midday. Morning snow accumulation from a coating to 2 inches, highest amounts from the higher elevations well NW of Boston into interior southern NH. Highs middle 30s to around 40. Wind E 5-15 MPH.
TONIGHT: Mostly cloudy. Areas of fog. Lows 30-35. Wind light NE.
TUESDAY: Mostly cloudy. A period of snow, some mix coast, mainly coastal NH, eastern MA, and RI, with some minor snow accumulation. Highs 35-40. Wind NE 5-15 MPH.
WEDNESDAY: Partly cloudy. Low 15. High 28.
THURSDAY: Partly cloudy. Low 14. High 26.
FRIDAY: Partly cloudy. Isolated snow showers. Low 11. High 24.
SATURDAY: AM sun. PM clouds. Chance of snow at night. Low 10. High 28.
SUNDAY: Mostly cloudy. Snow showers possible. Low 15. High 30.
TK, thank you for the update. Very light snow showers in Newton. A little coating on the grass.
Thick coating in Marshfield, with a cold drizzle now.
Coating here in Quincy.
Take a look at the Euro has a little more precip for Tuesday but then has a decent size storm for next Sunday. Storm looks to be a quick hitter. Let’s see what it says at 12z.
Thanks TK
Well NAM sure indicates a decent slug for Tuesday. NWS going with gfs which is a compromise.
Nam-http://mag.ncep.noaa.gov/NCOMAGWEB/appcontroller/Image.php?fhr=039&image=data%2Fnam%2F06%2Fnam_namer_039_850_temp_mslp_precip.gif&model=nam&area=namer¶m=850_temp_mslp_precip&group=Model+Guidance&imageSize=M
GFS

Euro has full northern and southern phase next weekend Close to an inch qpf and all snow on the euro. Whereas the gfs has an inland runner. Tuesday’s event if holds up on NAM will be an advisory snow for all of us and maybe even a warning south of the pike.
Here is the NAM snow map. Probably more like an advisory snow level storm.

Yawn…………….Morning.
What’s that white stuff falling from the sky. Oh it’s snooooooooow!
Looking out the window, looks like an accumulation of say 1/4 to 1/2 inch!!!
Not sure I can make it into work today. May have to call in. 😀 😀
Most of the rdar echoes still moving More Eastward.
Where’s the warm air aloft coming from????????????????
Btw, radar echoes just plain and simply do NOT portray predicted
conditions. Just does not. ??????????????????????????????????
Still beautiful out IMHO.
Yes, that is true. 😀
Something to enjoy even though doubt it will happen big nonetheless fun to look at

A little snow maybe in the form of flurries for tomorrow afternoon, but I am wondering about Sunday. Might be a quick hit but with a lot of moisture.
2-4 inches come Tuesday.
This is all that is left downstream:

Thanks TK.
Looking like a light snow event to impact SNE. Its not a lot of snow but the timing could have an impact on the evening commute. Right now level 1 snowfall which is a light snowfall on the scale and I am thinking a quick to 1-3 inches.
The weekend is another watcher so finally we seem to be coming out of the boring weather pattern with things to keep an eye on. Whether they pan out will have to wait and see.
Southern stream energy does not come onshore until late Wed/early Thurs for the late weekend storm. Will have to see if there is better agreement by later Thurs.
about 3/4 of an inch of snow here and still snowing
snow changing to rain do to upper atmospheric warming possibly a tad later more like noontime
small event tomorrow looks liken its going to be a nothing system for areas north and west of boston 🙁 light event south and east of boston.)
Hadi don’t get my hopes up for a storm next weekend. also its one of the times that i say don’t snow because i want to just get my finals over with.
Snow lovers may be disappointed in both Tuesday’s results and how the weekend system (or lack thereof) turns out. Nevertheless, stuff to watch. 🙂
0.6 inch snow here in Woburn so far. Very light snow falling right now. Changeover line sluggish but should be moving up soon. Precip. is not widespread thru the entire region but that is no surprise given how the energy is stretching out.
Going mobile. Have a great day everyone and be safe!
I can see the weekend storm NOT happening, however, I’m not so sure about
Tuesday. We shall see. 😀
Agree. Could be a surprise there. Elliot Abrams who is usually extremely conservative is calling for 2-4 in the city.
I’m not disappointed, expected and easy, I think Tuesdays event looks like a similar snow event to this one we just had 🙂
Not measure able here as green still visible. Turning back to ice now. Not a good time with schools just starting. Mac said the roads here to Watertown were fine.
When clearing car and shoveling walk, was in transition to rain.
Good solid 1/2 inch on ground. 😀 😀
While driving to work it did transition to rain, however just before arriving,
it went over to solid sleet and was sleeting pretty good at that. Something
is still coming down. I just can’t tell from 3rd floor window. It looks to be still
sleet, but cannot confirm.
Now we wait.
😀
Sleet still coming down here also – steady and heavy – we have an accumulation of sleet pellets more than snow. Grassy surfaces are still showing lots of grass. Quite heavy sleet and still no rain. Surfaces here are getting a lot more slippery.
Sleeting rather heavily in Sudbury – opened window and sounds like it’s “pouring sleet”.
Still sleeting here. I measured 3/4 of inch this morning.
Hadi, you in JP or Southie?

Just went outside. Here at the office (Roxbury) it is a mix of sleet and rain.
Based on reports here, this looks reasonably accurate. Looks like weather underground has IMPROVED their rain/snow display.

Nasty on the side roads here. Icy and heavy sleet right now.
ACL and MCL confirmed for Gronk. Tough loss and I feel badly for him.
Huge Ugghhh! Thats not only a loss for the rest of this year but probably most of next
As much as I wanted it not to be, just watching him, you knew it was. I feel so badly for him.
Any dreams of a SuperBowl period, let alone a Superbowl win is completely
GONE!!!!!!!!!!!! Not even sure we win a single play off game without the
Gronk. Perhaps the first one depending on the competition.
We certainly don’t beat Denver.
What a crying shame!!!!!!!!!!!!!!!!!!!
This is the worst injury year I can ever remember.
Gronk wasn’t here the first part of the year and Brady has been using him very sparingly. Not convinced you are correct, OS, as he hasn’t seemed to be a huge factor. Now, I’d agree that odds are not as good with a good portion of our number one players out, but that still doesn’t write the team off.
Check their offense numbers with and without him. Huge difference. He might not have a had a lot of action but his impact on others was huge.
Glad you told me before my SIL did – he isn’t as polite as you are 🙂
Yeah look at how bad RGIII was coming back from same injury way too soon. He’s done until next Oct/Nov.
One for sure is the cold. Don’t see it letting go for a while.
Looks like precip starting to shut off some to our west
Here is the euro for the weekend event at 150 hours.

Thanks again Hadi for these links to the Euro. Keep em coming.
I for one Love them!!!!
No problem. I will keep them coming. Hope other people like them, don’t want to post them if they bother people.
😀 😀 😀
If they don’t like them, then something is wrong!!!!!
AGree – keep ’em coming – both of you 🙂
High ratios for tomorrow so not a lot of precip needed.
Let’s see what gfs shows as it was a compromise between nam and euro. But 00z was a little further north so let’s see if it’s a trend.
Here’s the latest SREF Maximum 3 hour snow totals:
http://www.spc.noaa.gov/exper/sref/gifs/2013120909/SREF_SNOWFALL_MAX_f036.gif
It must be noted, that these would be the absolute maximum totals acheivable
with the atmospheric conditions. It is NOT the forecasted totals.
Still interesting to look at. 😀
12Z GFS snowmap for tomorrow. Moving on up!!!
http://www.instantweathermaps.com/GFS-php/showmap-conussfc.php?run=2013120912&time=24&var=ASNOWI&hour=042
GFS on board for a nice little storm tomorrow. Easily 3-6 with really good ratios.
What were the 0Z Euro totals for tomorrow?
Was that posted? I just don’t remember. 😀
Euro did not show much for tomorrow will post the 12z when it comes out
Great. Thanks
http://www.instantweathermaps.com/GFS-php/showmap-conussfc.php?run=2013120912&time=PER&var=ASNOWI&hour=036
AH you beat me to it.
I’m thinking it goes up more still. 😀
High ratios for sure like15:1
WWA or WSW for tomorrow? I am thinking WWA.
Right now Sure looks to be a WWA.
New 0Z data tonight, might dictate a change.
I wouldn’t rely on the 18Z data. 😀
Biggest snows near Charlie 🙂
My mom is freaking out about the snow tomorrow. Is it 1-2 inches? What is your verdict TK?
My mom is freaking out about the snow tomorrow. Is it 1-2 inches? What is your verdict TK?
I don’t know why this posted twice 😛 Just ignore it. I’m not a spam bot I swear 😉
I would say 3-6 from Boston south. Very sharp cut off. 6 is probably from Boston to providence corridor.
You’ll have to speak with TK, but IF you are asking Hadi And myself, then
we’ll say 2-4 or 3-5, somewhere it that range.
We shall see.
Depends on banding for tomorrow who gets what. Precip shield will be very sharp cut off.
WSW posted for the DC area.

Cool.
Of note: THE POTENTIAL FOR ACCUMULATION RATES OF 1-2 INCHES PER HOUR
😀 😀 😀
How much gets up here, that is the question.
It certainly HAS been trending Northward.
If this materializes, it would be an unexpected treat.
Although, I must say, there were some hints the middle
of last week even.
RGEM not on board with nam or gfs for tomorrow.
http://forums.accuweather.com/index.php?act=attach&type=post&id=211833
http://meteocentre.com/models/get_accum.php?mod=gemreg&run=12&type=SN&hi=012&hf=048&lang=en&map=na
Just under .2 inch of qpf. With expected rations, “could” eek out 3 inches.
So Canadian is on board for approximately 1-3 inches.
Assuming I am reading things correctly and I believe I am. 😀
Btw, Here’s last night’s UKMET accumulations, about the same
as this Morning’s Canadian.
http://meteocentre.com/models/get_accum.php?mod=ukmet&run=00&type=PR&hi=024&hf=060&lang=en&map=na
12Z UKMET will be available within the hour.
Hadi & OS,
Keep posted the links please! I think we should take the conservative route with snow totals as precip has been hard to get up here so I would say 1-3 inches Boston south.
Precip tomorrow, I think, is going to have to re-saturate a drying column as there will be a temp/dewpoint spread. Where the heaviest QPF is, there may be some borderline boundary layer issues. My best guess is …….
D-1 inch in Boston
1-3 inches from Hingham/Marshfield to Sagamore Bridges
D-1 on Cape because of boundary layer issues and/or it will be 33F-36F while its snowing, so its going to struggle to stick.
I don’t think it would take much to saturate the air bc of today’s storm.
Tom,
What you have laid out is a strict interpretation of the 12Z Canadian.
I would like to see the 12Z euro first.
You may be 100% correct. BUT I like the NAM 48 hours in, so I don’t
think we can totally throw it out at this point.
We may have to blend them all and come up with 2-4 inches.
Let’s see what the Euro brings in.
By the way, there isn’t much conservative in my blood at ALL! 😀
BZ posted a map of 1-3 from boston south.
Here’s today’s 12Z NAVGEM run with 6 hour accumulation ending at
18Z tomorrow:
https://www.fnmoc.navy.mil/wxmap_cgi/dynamic/NVG/2013120912/nvg10.prp.030.namer.gif
8 MM or about .3 inch liquid.
With expected ratios, that would support 2-4 or perhaps even 3-5 inches of snow.
So oldsalty if your calling for that amount than why does tk discount it in a rather fast way. 3-5 is nothing to discount.
Even 1-3.
Todd G tweet
@ToddWBZ: This system has been very shifty so still fine tuning and will have important update this afternoon. #WBZ
WHDH has 1-3 Boston and 2-4 just south.
From WXRISK 2-4

Old Salty sorry for stepping on your toes!!
Anyone is free to post a link. We all welcome it.
DON’T EVER think you are stepping on toes.
Many thanks for the link. Looks reasonable to me.
We shall see. 😀
Matt Noyes has 1-3 and going below guidance bc he thinks models will go lower today.
Well, let’s see what shakes out later.
Looking like a solid 2-4 inches to me, so far anyway. Always subject
to change. 😀 😀 😀
Still a fine mist here. Lots of melting of the bit we did accumulate. I’m not shoveling as what we have makes a safer, crunchy place to walk on the driveway.
Lol I haven’t even bought a shovel yet 🙂
Where is it hiding
You buy a new one each year?
I think that’s everyone’s concern. Models have been expecting alot more in terms of precip up here but just doesn’t seem to make it. Let’s hope for a couple of inches but my gut says we are going to miss out on alot of it.
I’m at Quincy medical still misting here. As Tom said thick coating in pembroke as well. I’m not sure if this would go down as one of my predictions before the 21st as its to be measurable amounts but most did have something to measure. I’ll let you guys decide. But either way my call for December sure is heading in the right direction.
Well considering it’s not even being shoveled guess what my decision is 🙂
I believe it was an event Vicki, another tomorrow and another Saturday night. So if I get 4inches tomorrow and you get 1 inch how would you look at that. Hope all is well.
Lol I guess we’ve had like 6 or 7 events, I didn’t know a coating was an event but to each there own
Charlie you are a funny guy 🙂 have a nice day.
John – I agree – if you get 4 inches tomorrow, it is an event – no matter what I get. I’ve always said that. The problem with your reasoning is no one got 4 inches today — no one got much of anything. So unless you have 4 inches somewhere, today is def a non-event…..especially a non-snow event as most of the accumulation was slushy ice.
Vicki I’m sorry but you just seem not to be reading things through. Vicki I’m talking and I thought we were talking about Tuesday not today as was tk. Ok. Enjoy the night .
One more try and then I give up as this is getting silly
John said: “I believe it was an event ”
Vicki said: “The problem with your reasoning is no one got 4 inches today — no one got much of anything. So unless you have 4 inches somewhere, today is def a non-event…..especially a non-snow event as most of the accumulation was slushy ice.
John said: “So if I get 4inches tomorrow and you get 1 inch how would you look at that. ”
Vicki said: “I agree – if you get 4 inches tomorrow, it is an event – no matter what I get”
John said: “Hope all is well.”
Vicki saying: “Nope getting frustrated”
As far as event – I’m going by NWS winter weather advisory criteria (unless someone has serious objections) and that is:
“More than one predominant hazard
Winter weather event having more than one predominant hazard (ie., snow and ice, snow and sleet, or snow, ice & sleet) meeting or exceeding advisory criteria for at least one of the precipitation elements, but remaining below warning criteria.
Snow, Ocean Effect Snow, and/or Sleet”
We are talking snow so in our case the hazard is snow
NWS criteria are:
3 inches averaged over a CT, MA, RI forecast zone in 12 hours
4 inches averaged over a NH forecast zone in 12 hours
We had to shovel the car off this morning Charlie.
R u kidding hadi? Lol shovel your car? Where do u live? White Mountains? Didn’t u get a half inch of snow/sleet, that’s what I got 🙂
Yeah we had to get the snow of off the car I saw many people in the Neighboors scraping the snow off
So it seems a consensus 2-4 from everything I am seeing. I will take that.
The higher amounts look to be down mine and toms way with the lesser amounts in the city. In around 9-10am out by 4am. So if your a snow Lover I pose the question again how can you be disappointed in that as tk said you would be. Just what is he looking at or going by.
4pm.
?? Not sure what you mean, John. Sorry
“So if your a snow Lover I pose the question again how can you be disappointed in that as tk said you would be. Just what is he looking at or going by.”
Tks post at 7:42am.
Sorry – still don’t get the question but suspect you and I are reading TK’s comments very differently. Either way – nothing matters until tomorrow night or Wednesday.
Well, a bit of a spirited discussion.
I had to SHOVEL my steps and walk. I had to brush away a fair amount
of snow from the car.
I didn’t realize that the GEM_REG and the GEM_GLB were different.
Here is the GEM-GLB qpf chart for period starting 0Z tonight and ending 12Z
Wednesday:
http://meteocentre.com/models/get_accum.php?mod=gemglb&run=12&type=PR&hi=012&hf=048&lang=en&map=na
You’ll not about 10MM up to Boston. That is a little more than .39 inch.
This is MUCH more than the 0z run last night. A trend?
If we took this literally, it could be MORE than 4 inches depending on the exact
ratio. 😀 😀
12Z Ukmet sill holds onto the 1-3,2-4 scenario:
http://meteocentre.com/models/get_accum.php?mod=ukmet&run=12&type=PR&hi=012&hf=048&lang=en&map=na
Are the light returns in southern Kansas and northern Oklahoma representative of the wave or disturbance thats tomorrow’s event ?
I’d assume the Gulf should begin opening up again later this afternoon.
Euro has .11 qpf for tomorrow’s event. It’s always been the lowest precip so I am sure that’s what we should go on :).
and to follow up on Coastal’s question below, what was the 0z EURO’s QPF ?
Because if it was similar to .11, then perhaps its settling in on a solution. Conversely, if it was like .02, then clearly there’s been at least a bit of a jog N/W.
How did the Euro do with the QPF for this event?
Don’t remember what it had. It was terrible for down in the mid Atlantic area.
Euro is way warm for weekend event so that seems to off the table. Lots of qpf but warm temps. Start cheering Charlie.
I actually always want a white Christmas, so right now it’s not the best news, I don’t like brown christmas’s 🙂
oh no, Logan reported .4 inches of snow for this event. Only have 19 inches left to spare !!!!!! 🙂 🙂 🙂 🙂 🙂 🙂
hahahahahahaha –
Hadi,
Looking at Wundermap it looks like the Euro wants to develop tomorrow’s system a little quicker than the 00z run. To me it looks like there should be an increase in qpf but I could be wrong.
The way these couple of storms have panned up here it’s probably better to air on the aide of being low.
Totally agree. On the comment above it was terrible on the mid atlantic do you mean the Euro was way off on qpf?
Yes
It’s a battle of American models vs. foreign models for tomorrow’s event.

67%
???????????????
67% of the US covered with snow. Most since 2003.
oh
What’s the timeline for tomorrow’s event is later in the afternoon?
Tj it starts at 10-11am and ends at 4pm.
Quick hitting TJ from 9 ish to around 4 and that’s the problem with snow totals. If you get under a decent band then boom but otherwise it’s low end numbers.
Hadi,
Re: weekend storm.
That’s still 5 or 6 days off. There is plenty of wiggle room.
This could end up being a decent sized snow storm. OF course, inside
runner rain event and total OTS is also on the table. 😀 😀
Check out the FIM. It is colder than the Euro with plenty of qpf.
Saw ghat yea plenty of time. One storm at a time 🙂
18Z NAM has trended with less qpf. Here is the snow map:
http://www.instantweathermaps.com/NAM-php/showmap-conussfc.php?run=2013120918&time=PER&var=ASNOWI&hour=034
This represents something like 2-3 inches in the Boston Area with a bit
more to the South. Now onto the GFS. 😀
But these are 18Z runs. I’ll go with the 0Z run.
If anyone is calling for either 1-3 or 2-4, I’m fine with it.
😀
Here’s the JMA qpf for tomorrow (LOW)
http://grib2.com/jma/CONUS_JMA_1000-500_SLPTHKPRP_48HR.gif
I don’t think boston will see more than 2 inches. The higher amounts toward south shore and cape with probably 4 inch totals.
Are we surprised !!! Not
Just like 2009-2010 all the snow down in the DC-Phili corridor.
I will take either OS 🙂
Vicki in tks post he said snow lovers may be disappointed with the results of the next two systems tomorrow and Saturday. What I’m saying is how can one be so with 2-4 inches of snow coming. Not sure how you don’t get that but all is cool.
John – you know we don’t have 2-4 inches yet right 😉 Perhaps – just guessing here – that’s why TK used the word “may” As I said we are reading TK differently and I’m not even sure why we are having this conversation so will let it go and wait to see what happens.
Per latest SREF, it has backed off on potential snowfall:
http://www.spc.noaa.gov/exper/sref/gifs/2013120915/SREF_SNOWFALL_MAX_f027.gif
Banding will be tough to figure out with this one. Wild card.
Nam has .25 QPF for Boston. Based on 12:1 ratio you are looking 1-3 maybe 2-4.
dbz banding looks pretty impressive but tough to pinpoint.
18z nam does not look right to me for all of the NE and mid Atlantic.
NWS tweet
@NWSBoston: Advisories may be issued later tonight or early Tue AM. Need to be more confident in where widespread 3″+ amounts are most likely to occur.

Btw looking euro ensembles for Sunday event it has snow to start and then slow changeover. Loaded system based on the ensembles.
http://weather.unisys.com/satellite/sat_wv.php?inv=0&t=l3®ion=us
Factors in favor of event tomorrow ….
1) this water vapor loop shows that the SE ridge is hanging in there and that the upper flow is still SW to NE.
2) trend is your friend. Overall, over the past few days, the models have trended a bit further N and W
Factors against tomorrow’s event
1) how often does an accumulating snow event happen with a NW wind ?
2) cold tomorrow, yes ….very cold, not at all. A daytime event at temps in the low 30s with questionable precip intensity doesnt inspire big accumulations.
3) I do think the column will be fighting drier air advecting in from the NW, battling the northern shield of the precip.
I’ll stick with my noon-time guess, but if it busts, I think it will bust in the direction of seeing less.
well – I see you were typing as I was typing, Tom 😉
Tom – question – you (and TK) have been batting 1000 – what do you see for tomorrow? I apologize if you said above and if you did please just point me to the right time.
Hadi and OS – I know I keep saying it but thanks for the links and updates. TJ – it’s fun to see you here 🙂 Hadi – I am very sorry about your disk but we are lucky to have you here more !!!!
Here’s a model that might be useful tomorrow:
http://rapidrefresh.noaa.gov/HRRR/
Pete has 2-4 on his 4:00 broadcast.
Anyone still have snow on the ground ? Got into the low 40s in Marshfield, so, its back to brown earth. 🙁
We never really had snow but the slush we had is still there. Even on the road.
Nice ! Is it much above 32F there Vicki ?
It’s been sitting right around 32 all day, Tom. And it does look nice with the white lights out front. We’ve had them on all day. It’s 32.9 now.
On the grass but not the driveway.
Anything that makes it through this evening plus whatever might occur tomorrow isnt going anywhere the rest of the work-week.
So you are thinking we need to push the slush off the driveway? Well, that wasn’t in my night’s plan 🙂
If its still on the driveway tomorrow evening, then I might push it aside. I think its supposed to get very cold Wednesday ??
Oh – very good plan. I can ALWAYS put it off one more day !!
Oddly, Hadi, we had more on the hard surfaces (roof, road, driveway) than on the grass. Ground not frozen enough so it soaked in since the water content was so high???
Unfortunately this smells like one of those situations where the models will end up adjusting downwards vs. upwards.
Not the GFS. 18Z GFS more bullish for tomorrow, not that it is a big event. 😀
Here’s the snow map:

With another bullseye not too far from Philadelphia.
Woods Hill Weather road trip to Philly !!
Bruins playing the Flyers or Celtics the 76ers anytime soon ?
Great write up by the nws this afternoon
http://forecast.weather.gov/product.php?site=NWS&issuedby=BOX&product=AFD&format=CI&version=1&glossary=1&highlight=off
Agreed !!
Very nice. Thank you.
A light snowfall with 1-4 inches. Its not a big system but maybe just enough to make things slick. Philly winter storm warning with 3-5 inches for them. They got 8.6 inches of snow yesterday more than they had all of last winter with that system yesterday.

Here it comes ……. Gulf starting to open.
Open baby!!!
To be honest very difficult forecast because of the potential banding set up.
18z brings in .30 qpf for us.
Based on 12:1 ratio that’s about 3.6 and based on 15:1 ratio about 4.5.
So whether a forecaster is calling for 1-3 or 2-4, they “appear” to be in
the correct ball park. I don’t think I’d stick my neck out for 3-5 at this point. 😀
This could still change a tad. I really want to see the 0Z runs. 😀
I know, one storm at a time, but I can’t help myself.
Here is the latest 18Z DGEX run regarding the weekend storm. INSIDE RUNNER/COASTAL HUGGER. TOO WARM:
http://www.meteo.psu.edu/~fxg1/DGEXEAST_18z/f144.gif
Still loads of time, but interesting to look at. BTW, It’s LOADED. We just need it to
move off some. 😀 😀
Have to leave. Here is the 18Z GFS so far on Weekend storm.
Also looks to be loaded. TRYING to develop secondary. Looks too late.
Destined to go over to rain:
http://www.instantweathermaps.com/GFS-php/showmap-conusncep.php?run=2013120918&var=PCPPRSTMP_850mb&hour=132
SE wind there. N.G.
18z is loaded with precip. First half .50 QPF all snow and then a changeover. .51 after changeover but temps aren’t that warm so it’s something to keep an eye on.
Bernie Rayo from accuweather
@AccuRayno: going to send an updated video around 6pm. Not impressed in Boston or S new England. still think in is N VA, S NJ, N DE. will send out link
I broke out my shovel for the first time and “pushed” away the slush from the front stairs and sidewalk. I probably could have saved some energy and waited for the warmup (42) later in the afternoon. Was it the first time for the rest of you here as well? 🙂
I don’t like this trend of “snow to rain” events and hope we get some “all snow” events as well. I don’t relish the idea of having to push slush around all winter long…UGH! 🙁
Absolutely agree Philip. I do not like snow to rain and really dislike ice.
Anybody north tomorrow should not plan on that much snow. Mike had 1-3 boston south. He said if some more moisture moves up south could get more. Harvey must be on vacation.
On the 5:30 news segment Barry gave his 2013-14 Winter Forecast:
1. Temps average below normal
2. Average snowfall of 40-50″
3. NO blizzards expected
I can get all the temps and snowfall but how the heck does anyone say no blizzards ?
I wondered that as well but Barry also mentioned probably not as much blocking as last winter. Could that be a factor?
I agree with the temps but think he needs to add to his high end of 50inches.
I think the blocking could be a factor but with that said you could still get good snow events without the blocking. I don’t think we will see a storm of the magnitude of the blizzard last winter.
Hmm, when did the weekend storm become a potential inside runner/hugger? I thought it was looking like it would be suppressed and pass OTS to our south?
I think the models are handling it horribly.
Lack of phasing allows it to cut inland just a bit.
Ah, gotcha, thanks Hadi
Lots of qpf for something that looks to zip right along huh? Not sure what to think of that track still.
Last weekend of December in 2012 we had a quick hitting storm that dumped a lot of double digit snowfall totals in eastern New England. Its possible to have several inches of snow especially if some good banding sets up shop even in a system that moves fast.
Last year? Darned if I didnt block that one out. Thanks JJ.
It was a Saturday the 29th of December. I had to drive to work in that snow.
Now I know why I don’t remember. That’s my second grands bday and everyone was stressing trying to reschedule. I block stress out :). Thanks again!!
Still hovering right at or barely above freezing here.
00z nam time. Over/under on more than 18z run ?
So far Logan has received 0.5″ of snow compared to last year at this time the total was 0.9″. Currently their snowfall “deficit” is at -2.6″.
Don’t forget that the southern stream energy for the weekend storm will not be onshore until later Wed/early Thurs, so things won’t be clear until then and that is probably why so much back and forth on the models/phasing.
Looks like about the same as the 18z nam so far. Will post numbers as soon as I get them
Looks like the 00z Nam is a little more robust!! Let’s see what the total precip is.
NAM will likely be a little too wet on its forecast. Cut the precip. in half.
Ahhhh Come on TK….Your dashing my hopes here!! Thanks for your analysis below.
Just calling it as I see it. 🙂
Sorry for the hope-dashing. Maybe I’ll be wrong. 🙂
I’m happy no matter what. Thanks for calling it like you see it. Hopefully will have a couple of surprises tomorrow.
Can you elaborate why?
Looking back on today: I feel that things went MOSTLY as expected. There was a touch more sleet than I though. Accumulations fell in the expected range, however. Icing seemed to be less of a problem than the media made it sound like it was going to be. Am I surprised? Not at all. Total snow/sleet accumulation here was 0.7 inch – the SAME as the last event.
Tomorrow: Basically a non-event north of the Pike, dustings/coatings. Build up from around 1 to as much as 4 from the Pike to the South Coast, with 4 being the exception rather than the rule. This represents no change in the thinking since last evening when it became apparent the low pressure wave would be close enough for “something”.
Weekend threat: I love how when ensembles say something it’s suddenly etched in stone. Discussions from NWS and like sources often talk up confidence 5 and 6 days out on an event because the ensembles agree. Well even ensembles can play out of tune. I’m not confident we get a storm this weekend, but I am not counting it out either.
Thanks TK. Nice job on today’s and the weekends (last)
Yes nice job TK and thanks for the update.
So what’s the call for Woburn TK?
1 inch or less between noon and 4PM.
TK is the grinch who stole our snow 🙂 of course jk
00z nam snow map. More than 18z run. But based on TK’s comment cut it in half. Still not sure why.

Pretty cool look at dbz which is easy terms is intensity of precip. Rap (rapid refresh)
http://www.twisterdata.com/index.php?prog=forecast&model=RAP&grid=255&model_yyyy=2013&model_mm=12&model_dd=09&model_init_hh=23&fhour=18¶meter=CREF&level=SURFACE&unit=none&maximize=n&mode=loopmaps&sounding=n&output=image&view=large&archive=false
Cool indeed ! Too far north, but cool !!
Look forward to seeing that on future storms.
Lol too far north bc you don’t want it to snow or bc you really believe.
Really believe. That would have steady snow in south-central NH and ME, which makes me say its too far north.
That shows done pretty decent bands. Not sure how Boston only see 1 inch TK.
Hadi the higher amounts down here.
?
For tomorrow hadi. I think 4 is the highest for this storm and that will be down this way Plymouth county parts of Norfolk county with the less towards the city, I think. Maybe a guess 1-2 for the city. I don’t think anybody gets over 4.
We shall see.
Philadelphia looks to be the big winner from this storm.
Nova just got upgraded to WSW. Am I only one on tonight?
.23qpf on the 00z nam but really cold temps so ratio is about 15:1.
Gfs will be telling.
Will be asleep before it runs, but am interested on 0z runs for what might or might not be happening next weekend.
3-5 inch snowfall for the Philadelphia area. Philadelphia more snow this winter than they had all of last winter with yesterday’s snow.
Still thinking a 1-4 inch snowfall here.
a 1-5 scale for road condtions
1 some minor delays. some slick spots mainly on secondary road ways
2. minor delays. slick spots on secondary roadways and on untreated main roads
3. moderate delays. slick spots. snow/ice covered secondary road ways. avoid secondary road ways
4 heivy delays. snow covered,ice covered roads. avoid roads.
5 severe delays and road closures crews not able to keep up with snow and or ice. do not travel.
level 1 road condtions for areas north of the pike
level 2 areas south of the pike. pike is a 2
Nice !
Hadi,
I’m watching the models to I’ll be up for the GFS run. Thanks for posting the links.
When you guys post just mention for Tuesday or the weekend. Good night guys.
Tuesday right now. I will focus on weekend tomorrow.
Ignoring tomorrow ………
While very late in the week, there’s a chance to moderate temps some from the arctic blast Wednesday, I interpret the models are signaling a push of additional arctic air into eastern Canada sometime next weekend. On tonight’s 84 hr of the NAM, look at that high in north-central Canada and look at the isobars around it and you can almost see that it and its associated very cold airmass will be headed southeast towards SE Canada.
Perhaps the timing will be right to provide some arctic high pressure to our region’s north. It will be interesting to see the trends the next few days …….
After this gfs run, forget the models and focus on Obs.
Tom are you referencing that for Sat’s storm. Why are you ignoring tomorrow?
Yes, Saturday.
Hadi, how about that storm in northeast Canada that gets infused with the disturbance tomorrow. 944mb!
Will be interested to see if any heavy bands setup in SNE. Where they do the higher amounts will happen and not going to know that until the event is unfolding.
00z GFS looks the same as 18z for tomorrow. Hadi back me up on this but it looks like .50 of liquid. Have a Good Night!
.32 For Boston but again high ratios
00z gfs. 2-4 seems to the theme.
http://www.instantweathermaps.com/GFS-php/showmap-conussfc.php?run=2013121000&time=PER&var=ASNOWI&hour=036
Kevin L from changed his map to 2-3 and spots of 4+.
I’m heading to bed. Catch up with everyone in the morning. Hadi what do you think on the 00z gfs? Looks kind of similar to 18z.
My low amounts have nothing to do with whether I want it to snow or not. To me it’s fine either way. I tend not to wish for or against anything. In the name of science I just forecast what I think will happen and see if it verifies. I love snow, but I don’t get disappointed when it doesn’t snow. It’s just weather. I love all weather. That said, my reasoning for less snow from this next pass is: too much dry air, and again, I think the model forecasts for snow are over-done.
This is one time that being south of Boston in winter will be good !
Radar
http://radar.weather.gov/Conus/northeast_loop.php
On TV. have seen 1-3″ forecasts Pike and south. More to the south.
Seems like a consensus of 1-3 for Boston area and 2-4 from Brockton south. Enjoy Charlie!!
Agree as I was telling you that last night. There is an outside shot at maybe six inches somewhere on the south shore.
“as I was telling you”
Where did you tell me that? I saw you say maybe 4 inches. And that the most would be south which was clear along.
Funny thing about Charlie’s area is in situations like this it often falls in the middle. I used to live there and would often get frustrated during the winter. It would be on the wrong side of the rain/snow line but in events like today where areas to the south should get more snow it juuust misses the area.
Well doubt any mixing occurs around his area today. But I am sure we will get an accurate observation from him :). Only mixing should be confined to outer cape and the islands.
Hmm wheres this dry air thats supposed to limit snow amounts today? Looks like prime conditions already, at least at the surface.
I think today is cut and dry regarding amounts.
Red sky this morning, looks ominous 😮
Take watch sailors when you see a red sky.
red skies at night, sailors delight
red skies in the morning, sailors take warning
I am seeing that red sky in the distance outside my window in CT.
A lot of schools closed here today and I am waiting for the first flakes to start falling.
Updated blog!
West wind is not your friend. 😉
