Ending out December with a Potential Pattern Change

Weatherbell has a canadien hires now. Will be interesting to see how it performs. 

It's been running as the GEM-LAM for a few years now I think but only ran once per day to hour 24, this summer they upgraded it to a full cycle(4x daily) and to hour 48. It used to be excellent for it's limited range and was a great tool to use in borderline events, but don't have enough sample size now to know how it's been doing now that it's a "real" model.

Almost drawn out of the 2007-2008 winter...that depiction on the Euro.

We got 140+ that winter.  We meaning me, Brian, Jeff and Eric.  I personally invite that winter to enter the door, as I only got to see the huge piles in January as we came to view the house we bought and moved into on March 31 that year.  At that point there was 2 feet on the level left.  Clearly we moved in 5 months too late.

 

There is a best case taking shape here....07-08 transitioning to week-mod Nina climo with blocking for Feb-Mar.  I feel cautious but could envision that progression.

I don't mind pellets if I get some solid snow first. I know many here have this almost anaphylactic reaction to sleet, but I definitely don't mind it...as long as it's not like 70%+ of the qpf in the system.

 

At any rate, there's going to be a lot of different looks on that system.

That would be a good widespread winter event. Low goes west but solid thump.

 

 

The low actually gets squeezed out south of SNE at the last second...very vintage look from those SWFEs a few years back...primary tries to get into NY State but then just dies as it splits off to a secondary reflection that goes near the Cape. Runs into that brick wall of cold at the sfc.

 

 

At any rate...that system is still 6 days out so it's going to change a ton. This run actually slowed it down and almost let the energy behind it catch up to it. So we don't get two seperate systems like previously (before we had one on the 28th-29th and one around the 31st)...with all those embedded shortwaves, who knows what it will look like 2 or 3 runs from now.

Any Met RIP and reading is going to have issues.

 

Even the ensembles are having issues right now...they have been flip flopping a lot.

 

I made a post a day or two ago about how even taking ensemble mean solutions verbatim is not much better than taking OP runs verbatim when the uncertainty isn't accounted for.

It's definitely one of those patterns where you have to look at where the anomalies are and then judge it for yourself. For instance you know the risks of features like AK ridging and SE ridging and as well as +NAO location. You can't necessarily cancel winter because yellows at 500mb are overhead. That cold is low.
