CMC looks south-er so far at 96. ULL centered about 300 miles SW of 12Z... closer to 00Z last night.

Good snow 132, 135!

Scheisse!
A true classic, the North trend only when it screws us.

You think they do it randomly?
This should probably move to banter, but I feel obligated to respond as I'm studying data science.
The most often-cited resource on this is: Walsh, John E.; David Allen (October 1981). "Testing the Farmer's Almanac". Weatherwise.
The findings of the above study (University of Illinois) were that monthly precipitation and temperature forecasts were 52% and 51% accurate over a 5-year study period, respectively. Given an anticipated random accuracy of 50%, this suggests that their method (if any) does not significantly increase the forecast accuracy above simple guessing.

Here's the Eps mean . I think that's the control^
It is. To anybody who doesn’t know (me a few weeks ago), there’s a helpful little identifier after the ECMWF Ens tag.
[M]=Mean
[C]=Control

I'm plenty happy with that for now. At least it finally brings some colder air down so those HP give us a legit chance.

It used to be part of the Gefs ensemble package
Yeah it used to be on the member panels along with all the members, but now it doesn't seem to be anywhere.

Control with a 999 low off OC early Sat morning . -850s... check ...surface... a couple degrees colder we in bidness .
Does anybody know if WxBell allows access to the GEFS control like the EPS? I can't find it...

An ignorant question I know, but when actually are the approximate times that the 00Z/12Z ensembles tend to become available?
Depends a lot on the forecast range you're waiting for, but WxBell lists the following:
GEFS: 10:30-1:20
EPS: 1:45-2:50
Since we tend to favor ensembles in the LR, my personal rule of thumb is to wait an hour until after the OP starts.

Has the CMC started the 12z run???
Only just

GFS looks much closer on the 9th & 12th. Looking forward to the ensembles

EPS has a signal for coastal storms again around the 11/12th and then again around the 14th.
I'm loving those SLP means from the 8th-14th. Looks like lots of action!

Those two energies do phase off the coast on the 5th... if they phase sooner, we get closer?

GFS moves closer. Gets frozen into VA/NC.

I have nightmares about WARs like that... Not again.

The HH GFS shoots the would-be post-NYE coastal out to sea. Then nothing until epic cold front part III on day 13. Sigh
-
GFS looks like it’s trying hard to build a coastal after NYE but it’s too late. Still a really different look.

I don't hate the GFS 28th trend for the last several runs...It's come a LONG way
