Super Snow Sunday 2/15-Party Like it's 1717


40/70 Benchmark

Recommended Posts

I have NEVER Seen a more Hilarious Run in my weather career!  It says FU to SNE!!  Snows South of it, SE of it, East of it, NE of it AND North of it!  But barely in it.  

 

It it was trending this way for a day but still hahaha.  

:cory:

You get 10"+ on that run and all of SNE is warning criteria assuming a 15:1 ratio(Which is not at all unreasonable). Look again.

That mid-level and ULL track is awesome though...tighten that up just a shade and I think you'd see the very heavy snows that are shown in Maine further SW.

The 850 low is basically on top of Cape Cod at hour 72 and all CT east of 91 can muster is 0.5" qpf. That sounds really low for those kinds of upper levels with H5 south of LI.

From what has been described..that norlun is going to help some lucky zone really jackpot. Whether that's over Long Island or Sne ..noone has a clue..but it's there on most models

maybe it will be the creature feature from Ray's climo  book of  night terrors that screws BOS-NE mass in between.

Agreed. I don't think it means 1.5" of qpf for SNE or anything, but I could see the totals being underdone a bit and model guidance adjsuts up a bit as we get closer. Usually I will say the opposite, but this is an exception.

 

All it would take is for the mid-level center to bomb out just a hair faster and thus enhance the inflow...with the powderkeg that this ULL is, I could easily see that happening.

Will did mention Mid level low deepening was Very Critical for this inflow challenged ULL . Guess the deepening wasn't rapid enough

 

It seems we have a good enough ULL track with decent confidence now we need mid levels to juice up faster

 

I'd LOVE to see 7H heights Near cape cod at 12z on euro and compare it to GFS's 255

Sorry for that everyone, I dropped a turd at a critical moment.

 

Reading a euro run while driving in heavy traffic on old cache ftl.

 

QPF verbatim may satisfy, but synoptically we still have work to do for this to be a higher impact event on SNE.

 

As I commented yesterday, tons of vorticity rounding the trough, and all these multiple ensuing surface lows bouncing around are mucking up the inflow. Not much of a difference from 0z. Blizzard conditions will be reached briefly in eastern SNE, but we are oh so close to something bigger.

We have something bigger on the models, only the GGEM screws up the flow with multiple surface low centers, other guidance is pretty much a singular surface low center.  EURO is a single surface low.

Not impressed outside of Maine.  The best forcing takes a late, wide turn around the ULL.  The feature positioning looks impressive, but it's deceptive.  This still could be moderate impact throughout and pretty significant for the same areas that have been getting hammered.

We need some tight mid levels exploding sooner, not just a "pretty track"

 

I think it is VERY CLOSE

My hunch is that further slowing and deepening will show up in next two runs as much of the surface development is taking place southwest of the ULL over SK-ND at this time. This could tend to consolidate the track as much as 2 deg southwest of depictions and bring the ULL over the coast closer to central NJ than NYC, which could allow both more recurvature and a faster trend of explosive cyclogenesis. Euro 12z is about halfway to what I believe will be final verifying central pressure at BM (972).

 

Based on those rather minor adjustments, first call would be 30-40 inches for se NH and coastal ME as well as a few parts of ne MA, generally 20-30 in e MA, trending down to 8-12 in w MA, 6-10 in ALB. Would expect a ribbon of higher amounts also across ne CT towards central LI (15-25) with perhaps 10-18 for PVD and some parts of se MA. Not expecting much mixing with the rate of pressure falls overwhelming frontal advances, possibly ACK changes over briefly. 12-18 for Cape Cod. Wind gusts to 85 mph on exposed coasts.

 

For Canadian side, 75-125 cm (30-50 in) potential for s NB, PEI and inland NS, 20-40 cm coastal NS. Wind gusts to 170 km/hr in the most exposed locations, 140 km/hr more widespread. This would be an extreme weather event for parts of Maine and Atlantic Canada.

 

(specific numbers for later check, BGR 35" PWM 37" CON 29" BOS 24" ORH 20" PVD 14" BDL 12" BDR 7" ISP 16" JFK 5" ALB 6" YHZ 70 cm snow 15 mm mixed, Moncton NB 120 cm, St John NB 90 cm).

Eduggs, how do you not see this thing being a high impact blizzard for SNE, especially eastern areas, from Cape Ann to Cape Cod.

 

While I'm not speaking for Eduggs, but this very easily could become quite an annoying system in SNE. GFS and Euro only put out .5" of qpf.  Say that's right......yipee....5-10" of snow.  Won't even notice it when there is 2-3' already on the ground.

 

If the qpf is that paltry and .5" falls over that long of a duration then most places best chance of qualifying as a Blizzard will be as a ground Blizzard.

You're just a bundle of positivity aren't you.  Perhaps Albany will get some snow this year.
