That’s part of the fraud 5 isn’t it 

strong back end dump. Rarely ever materialize and If it does it is 1-2” 

I doubt it will be more than that this time but it could be a high impact 1-2" if it does happen. For areas that tickle above freezing, say, south shore or something., it would be a flash freeze and then the inch or two of powder on top of it. That can be really nasty. 

But yeah, I don't think it will add a bunch to the accumulations like a march 8, 2005

I mentioned this last night, too.  Its like every run folks are like, "this looks cold" like it's some sort of surprise but it's been hashed out now since Day 9 that yes, this will be cold.  

Even this morning it's like, "that should be cold."  Yup, the Mets on here have been saying that for literally 4 days in a row.  

But even if you know the SFC temps are wrong, I guess just seeing them probably leaves that small doubt.  

Just read BTV AFD 15 to 20 to 1 ratios in your hood,then winds in the 50s with temps near 0,epic drifts.

Anyone willing to guess whether we manage to get more IP than ZR in central Mass? Guess the memory of 2008 won't go away.

This is highly unlikely to be another 2008 in C MA. Mostly snow and sleet is My guess.

No.....this post is. We just had great blocking in March and will within 2-3 weeks.

My post wasn’t for THIS storm specifically. There has been numerous systems over the past 7 years (last March not withstanding) where ridging in the N ATL is there initially looks good at D5-7 but then poof. Lower heights in the NewF region usually just blow through any heigher heights to the N.

Still some decent spread on guidance. I'm still hedging slightly colder but I believe we're getting close to the final solution. Getting inside of 3 days now. Won't be surprised at a tick colder and then a last second bump north after that. 

 

Sort of agree...  I give that 60%, but that's mid way on a positive slope (so to speak...).

It's the low N-S amplitude in how this is coming nearly due E egress off the Pacific Ocean ... it isn't doing certitude any favors here.   

Plus... the N/stream involvement is adding another wild-card... Not sure that's clear until the southern stream is amply sampled and resident in the flow...such that it's transitive effectiveness on modulating stream interactions can be assessed properly by the models.

I just wish we could figure out where the zr/ sleet line is. No one seems to be able to forecast that . Do we get 3-4” of sleet on top of the 6-8” of snow or do we get an hour of sleet and 10 hours of zr before flip back to snow..

Not over you

Yeah... if one wants to engage in this past time ... one must be aware/remember that there are all kinds of different intellectual colors and intents for other's engagement - haha...

Thanks. Crazy how close the gradient of projected snowfall is just from Worcester to Fitchburg. That was the reason why I was wondering. Figured it probably wont go to plain rain.

What about eastern Fairfield county?

On the back bumper of your car?  I'd say about 1/32 more than the actual hood - you have to remember ... even after 8 to 10 hours of non-use, the engine block is cube of iron and will continue to liberate small small quanta of therms to molecular water that is trying to free...

Yeah that's kind of what I've been thinking. I think those solutions that tickle it into S NH will eventually settle southeast a little. Or I could totally see one of those scenarios where nowcast time comes along and the sleet line is hitting a brick wall and it just never quite makes it as far north as guidance says. There's some competing forces here and it feels weird to hedge colder aloft because usually my instinct from experience is to shove the sleet further north than we think on SW flow..but this is a somewhat different setup...the Arctic high really doesn't get in a better spot even if we drew it up ourselves. It going to provide some resistance...even some of that will be felt at altitude I think. 

Buuut....always some uncertainty...the source region of this system is definitely impressive. That rich gulf moisture will provide a good opponent for the Arctic dome. 

Yeah that's the weird thing. Say the low goes near ACK with that cold high...sort of limits the IP potential near the NH border. But that plume above 800 is a furnace...sort of goes against instinct.  I think there is going to be a nice CF area that probably pulls a 94 and pelts..maybe 128 for a time?

So you're saying it won't be an issue.

Euro op and EPS really start to tilt more NNE-SSW with the low and show even a possible meso low near the outer Cape. If anything that helps lock in ageo flow over the interior and makes it easier to collapse back south. Something to watch. The weight of single digits and teens over the interior will want to press south and weighs over the area like truck. Wants to move south.

Can it be like Canton 128 and not Woburn? Thanks.

??

Asking to nail down a sleet/ZR line 3 days out deserved a bun. 

Id prob hedge more sleet for you at the moment with maybe a bit of ZR but we need to pinch the spread on the models a bit more before saying anything with confidence on that front. The only part that is close to a lock right now is you will not sniff freezing at the surface.

not saying anything - i'm being a sarcastic d-bag ... 

my hamster aint on the wheel yet - sleepless night whence the whoosh over my head. In all seriousness though, starting to worry a bit about ice here in Trumbull - about 4 miles north of Long Island Sound. Ice would be rare here but....
