picture perfect progression here. just shows how the split flow comes together with the 50/50 to lead to a bomb

Look at the expanse of the storm, that would rival 1996 in terms of a NESIS score.  Keep in mind thats straight 10-1 on a low resolution control run, which would be very low given that h5 and surface depiction.  Yes I know its a day 20 snowmap, but it shows the potential of this pattern.

Yeah I know this is a snow map way out there for the control member...but damn, that's still quite an expansive area of 12"+!!  I don't know if we've seen that kind of signal yet this year, hopefully it's real.

(ETA:  Just as a matter of interest, since you mentioned it, I believe the 1996 storm is one of only two events that hit NESIS level 5?  March 1993 being the other one.)

21 days.  We're going to lose a few.  This is going weed out the weaklings. 

Yup, most definitely.  If (if, if, if!!!) this kind of progression actually occurs, you know there will be tearing of hair and gnashing of teeth with every single ops run once it gets within range to appear on the ops.  Of course, if we can manage some event prior to that time, it may mitigate some of that.

all this talk about Feb 22-23 is super scary. its 20 days away. The EPS snowchart lit up today for threats way before then

Yes it is. I've already made my non-scientific reasoning why...I mean perhaps this year could finally be the year to break the post PD-March 1st bad luck streak! Ya never know.

Now THIS here: I'd MUCH rather be bet in something for this weekend...why? Because our history of PD weekends in Niños is frickin' epic! It just "feels" like a better chance (not scientific, just a feel). Now scientifically, what @psuhoffman is saying about the 22nd/23rd being better odds makes sense with the -NAO flexing and all. Now of course...if the timing of the relax of the flex is moved up a few days...then maybe PD :ph34r:

This is an Ensemble Mean for 7 days. That’s some good consensus. But it is the control, so what does that mean? Is the GEFS similar for the time period?

It doesn’t mean anything except the pattern during this period is conducive for snow


.

It does also mean we have a legit shot at a MECS/HECS, which is something that couldn't be said for the last 8 years.

We have had several chances for mecs/hecs in the past several years

Dec 2018 and Feb 1 2021 were really the only two legit changes we’ve had for a hecs storm since 2016 and neither was really as good as this setup. 

This is a bit off topic, but I keep remembering there was a massively hyped HECS that was supposed to be a few days after Christmas a few years back. The models I think had it for a very long time up until a few days before. Was that 2018?

No, that's the control run.  It's essentially the Euro op run out to Day 45.

I think it was early January 2017?  We had this amazing look for a huge overrunning event that was very consistent from like D7-13.  But it got within D7 and the arctic air won and we got a very cold, but mostly dry, week in January.  Think we got a small clipper to drop a dusting-2".
