There's still part of me that is leery of a huge swath of SNE just flashing to heavy snow sometime between 09z and 15z Saturday...the parts that flip over to non-snow in the first place of course (which could be most south of rt2 or even the NH/VT borders...we'll see). It will obviously take some good classic CCB dynamics...but they might make quick work of these 50mb marginal warm layers we're inspecting with a magnifying glass every run. Thankfully we still have a solid 12-18 hours to really figure it out.

Agree. I don't have cross-sections yet from this run but based on 0z Euro it's marginal 850-800 temps between 6z-12z that we need to overcome in eastern SNE. Do we have a good CCB? I think the more southeast H5 digging on the 12z Euro is a positive trend.

But it's more than just the verbatim interpretation of the Euro: RGEM/NAM are significantly warmer. 850Ts are > 0C north of the MA/NH border on the mesos.

And a compromise between mesos / globals will not be good enough for Boston. I think we'd need globals to be correct and 48 hour mesos to be wrong for Boston to top 2-4" total.

Should be a fun event to watch from the outer fringe looking in. I hope some of you CNE folks get smashed.  Early Spring snows are pretty sweet in the Northeast no matter how you slice it.  

Got Sunday off? Maybe we take a weenie ride to weenie ridge near Wachusett?

Agreed. Need to see the mesos start to reverse course at 18z otherwise people can get burned by the euro (again).

The mesos carry a lot more weight on March 31st imo.

I will take that Euro op run any day!

I think it's nuts.  Something seems funky around hour 48-54...I think based on the mid-level lows and even the thermal profiles showing dynamic cooling that the strong precip babdshould be further south in SVT/SNH instead of up around MPV.  That's the difference between 3-6" and 8-14" the Euro wants us to believe.

Yeah I am not buying it either but I wish it would verify lol.

 I've just had years of conditioning  that always leads me to error on the side of the mid levels flooding with warmth sooner rather than later.   I keep a similar rule in mind about precip rates being over some by the models  but that is partially due to the shadowing I sometimes see in my location.

Yeah I guess I just saw a couple things that I thought would argue for that mid-level banding look further south.  Not a ton but it'll be something to watch. I'll say I'd rather have the EURO going big over any other model but we may still mix with sleet.  It's pretty darn marginal there for a while and you can see an upslope/downslope signature to the mid-level temps.

Am I fooked too then? I hope so.

I think anyone north of Rt 2 should be prepped for an outage. I said yesterday I wouldn't be surprised if this was like Thanksgiving 2014 in terms of outage significance. Nothing like October '11 or December '08 but still quite a few outages.

48 hr burp run, sort of like with the blizzard?

Seems a little odd that BTV does not even have a WWA for Burlington when they show this:

Location At least    Likely    Potential for     >=0.1"      >=1"      >=2"      >=4"       >=6"      >=8"     >=12"     >=18"
                       
Burlington, VT 0 3 12 87% 82% 75% 60% 47% 34% 16% 3%

I know they are only expecting 3 inches with minimal impacts in the CPV per the discussion but if their products say there is a 47% chance of warning snows verifying you would think a Winter Weater Advisory or a watch would at least be up

What do you think for Gore and Whiteface I'm heading north tonight

He might have to eat them all to survive the power outages, can you eat chicken raw? Hope his grill works, sh it EEk might be eating his Chickadees to survive.

Funny you should mention.  I was outside earlier and noticed there is an unusual quantity of chickadees out there. Quite enjoyable to stand about 4 feet from the feeders while they voraciously feed.

Tough call.  The thing Gore has going for it is that place does really well with SE low level flow in both precip production and that upslope should also help keep temps cooler in the mid levels.  SE flow from GFL to Gore is a pretty steady 3,000ft rise and I remember growing up skiing there they always did well in those systems where upper level winds are SW but it's SE lower down.  

Theres a reason the models crank the QPF there.  However I also have this feeling we all see more sleet than we think...HippyValley mentioned it and I always feel that way too that in these cases it always seems like the sleet comes faster and further than expected. It will likely wash out but we may see the first half of this system be like a raging sleetstorm for many with pockets of snow...that would be my concern.  

I wish I could see the Euro 800mb temps.

Kind of an odd shape, with snow getting to Quebec City then apparently dying before it can move to the east.  It's like the storm track does an abrupt right face and strikes out toward Bermuda.  (Or at least Sable Island)

It looks to move ESE when it's below LI, GFS does this further south, And the Nam comes further north before it moves east, That' what i am watching is to where that takes place.

Very much agree sleet cutting down totals is my biggest concern I'm pretty confident on the QPF

You come close to 0C at 800mb at 12z Saturday on the Euro but you're all snow. I upgraded from freebies.

Jeff I had to laugh about this map for the next 7 days, I cmon man, CNE NNErs crying for their Mommas, Golf courses opening May 1st and EEks back yard snow clear date pushed up another week. This would be awesome

May 1st? Our course traditionally opens the last week of April on average. That would be further into May than the 1st. The 8th if we get a warm up?
