WB 12Z AI ensemble looks darn good to me....

[Eskimo Joe]

Both the 12z GEFS, 12z AI-GEFS, and the 12z AI-ENS have several warning level hits from I-95 and points west. We may not be that far off from something here.

Good vibes, Happy Thanksgiving

These models are much like me after this edible at family thanksgiving. Kinda don’t know what’s going on, but I’m having a good time.

We're scared from a decade of rug pulls and great patterns that are just two weeks away. It's smart to be cautious. A legit advisory level snowfall before Christmas, that doesn't melt off in two days, would do wonders for this subforum.

He’s not a snow lover and his comments to me are unusual for him  so I’m quite hopeful and 12/5 looks good analog wise

Oh okay then (this afternoon AFD from LWX)

LONG TERM /SUNDAY THROUGH THURSDAY/...
A more active weather pattern is likely to build over region late
this weekend and continue to the early parts of next week bringing
multiple chances for wintry precipitation. The first chance in the
long term period for wintry precipitation will occur Sunday into
early Monday morning as a strong sfc low passes to the north with
it`s attending front moving through our region on Sunday. As
precipitation associated with the front moves into the region, cold
air in place ahead of the boundary may allow for some front end
wintry precipitation. Additional wintry precipitation will be
possible on the back end side of the front as cold air rushes into
the region. Model guidance continues to have considerable spread on
precipitation types with freezing rain and snow possible. Based
recent trends,the best chance for impactful wintry precipitation at
this time will likely be in areas along and west of the I-81
corridor.

A brief lull in precipitation is likely on Monday, but a strong
coastal low passing to the south of the region will bring another
round of precipitation to the region Tuesday into Wednesday. Weather
models have a range of solutions for the Tuesday event with some
solutions having a combination heavy rain and some wintry
precipitation and other solutions indicating the chance for a
decent accumulating snow event. National Blend of Model plume
graphics really shows the uncertainty with snow solutions ranging
from  0 inches to near 15 inches of snow. At this time, we continue
to have low confidence in the wintry threat early next week, but
it`s a period of note worth keeping an eye on for planning purposes.

0-15 inches? Sounds like a CWG forecast

Amen brother!!!

[jayyy]

GFS seems to be making subtle movements toward the Euro at H5 since last night.

If we keep expectations in check… a solid early December 2-5” type event (1-3” closer to the fall line and 3-5” up this way) that doesn’t melt immediately would do wonders for this forum. Especially with a threat or two possible behind it.

I’d obviously love a warning level event with temps in the upper 20s up this way, but I’m not going to bite on the possibility of such a solution until 72 hours out.

Mets just want turkey and said just put in 0-15 inches to cover the bases

I had to laugh.  0-15”  What a science

Less confluence and stronger vort thru 84. Let’s see how this goes.

Probably going to be a warmer run. Hope I'm wrong.

[Terpeast]

Yeah I don’t like the less confluence part either. Looks more like 6z

[WEATHER53]

It takes 2.5 days for models  to cycle thru  the CAB soblook for either tomorrow night or no later than noon Saturday for sizable snow amounts to appear uniformly

I mean considering how much more euro is weaker rather not start big south moves each run. Little tick north before comes south again is fine be me.

Makes sense. iirc the deamplification trend usually starts at 3-4 days out, no?

otoh, the high moved way off to the east and we need it to stay to the north of us.

Antedecent southeast winds are a death knell for us. Hope this isn't a trend.

 Hmmmm  not good  unless ur in mountains
