12z Euro

[earthlight]

Slightly faster and a bit further north with the December 5th event thus far through 138 hrs.

[earthlight]

Sub 1000mb low off the Mid Atlantic coast at 144 hrs...looks like a big hit for DC and the Mid Atlantic. Precip all the way into Southeast New York and moderate precip to Philly.

stronger with the first sw, NAO block loos better.

Turning the coast at 144, probably OTS, but much better than the 0z

[earthlight]

H85 0c line is off Ocean City MD at 144 hrs and then runs due south to the Outer Banks...very cold aloft.

I'd Love just a couple inches from this storm, maybe just 1-3 just to get in the winter mood.

[earthlight]

150 hours deepening rapidly off the coast of the Mid Atlantic..still significant precipitation in the Mid-Atlantic and DC getting hammered..surface a bit warmer but probably 33-35 degrees and snowing.

[earthlight]

Sub 990mb bomb just southeast of the benchmark at 156hrs

[Alpha5]

50 miles from a MECS at 156

[hudsonvalley21]

Is it a quick mover or does it give a good duration of precip?

[Kaner587]

Sub 990mb bomb just southeast of the benchmark at 156hrs

Doesn't sound like we get too much in the way of precip...maybe .1-.25?

[earthlight]

Rough QPF Estimates

NYC: >0.20"

PHL: 0.25"

DCA: 0.75" maybe more

[earthlight]

Literally less than 50 miles from being a huge CCB deform band for everybody at 156 hrs

[LVblizzard]

Gets down to 988mb at 156. A little farther west and we'll be having some fun this weekend.

[earthlight]

Wow...absolutely bomb at 162 hrs..Long Island gets hit with heavy precip

[earthlight]

MECS in Boston at 168 hrs with a huge CCB

[LVblizzard]

Literally less than 50 miles from being a huge CCB deform band for everybody at 156 hrs

Still that way at 162...the block is stalling the low off the coast

A nice snow event for everyone it appears

Its extremely interesting to see the more amplified look on both the EURO and the GGEM....

[earthlight]

986mb just outside the benchmark at 168 hrs...Eastern LI getting raked...and heavy snow throughout most of Eastern New England

[earthlight]

0.50-0.75" for Central and Eastern Long Island..probably more for Montauk and Southern New England..still snowing at 168

That was always a possibility if any storm did develop due to its intensity (the block). Maybe we were all focusing on the wrong time period lol (dec 8-11th)?

[earthlight]

Probably an all out blizzard in Boston at 174 hrs and north into Maine

[earthlight]

Probably over an inch of liquid for Boston and most of Southern New England...CCB is still hammering away at 174 hrs..the surface low is sub 983mb

[earthlight]

Wow..the system retrogrades completely northwestward at 180hrs and is now slamming all of New England including Northern CT/MA/VT/NH with the CCB...surface low is still sub 985mb east of Boston

[Manny]

WOW. I mean, a little more to the west, and this clipper of 1-3" turns into an all out MECS for Philly and NYC. Two nice threats on the horizon.

[earthlight]

Miles from being a MECS or more in PHL-NYC...a slam dunk MECS this run in DCA...Eastern Long Island..and New England.

[earthlight]

Are we high and dry this whole time?

Northwest NJ is the real screw zone...we probably get 0.20-0.30" out of it..but the heavy stuff misses to the south and then northeast. Long Island gets absolutely hammered especially the east end.

[Manny]

Snow-hole. DC cashes in and so does Boston. lol NYC will get there though.

[hudsonvalley21]

That is what we want too see ,is when the low is effected.

[LVblizzard]

The 500mb map is insane...a huge ULL sits and spins over the NE while that surface low is still bringing snow to New England.
