if this gets too close to the coast and deepens there will be the possibility of mixing issues along Jersey coast and eastern LI - happened during the Jan 96 Blizzard I remember when I lived in Northern Ocean County NJ......probably in other stronger events also......

Indeed, but as long as the mixing just stays way out east or south of us, we'll be fine.  In storms like this JFK jackpots even if there is a slight bit of mixing (although don't expect the mixing to get back here)-- see February 1961. Higher qpf > trumps any slight mixing issues.

So, the UK is the least snowy of the 3 major global models that have run so far and it shows 12-18" for the entire region for 2/20 and for DC to Boston really.  The least snowy.  The GFS shows the most with 18-32" and the CMC shows 12-24".  I've never seen anything like this before in decades of tracking storms - consensus on an historic east coast snowstorm 6 days out.  Obviously, storms like this are rare, so it might not happen at all, but this is as strong a signal for a significant to major snowstorm one is ever likely to see this far out.  Euro up next and I have no idea what to expect.  What's bigger than BECS?  

January 2016 was bigger than any I've ever seen, the most widespread 30 plus inch amounts across the most densely populated regions.

Yes but is that change correct or noise. Here's the last six runs and we can see some buckling of the northern stream jet but it really takes tonight's 00z run to bring home the bacon. I want it.

00z models are famous for being the first to catch changes because they get new upper air data and they have the highest verification scores.  In 1993-94 our storms always trended snowier/icier with the night time runs and they ended up being correct.

Thanks Walt, I'm very worried about the winds Sunday night and into Monday too, looks like Wind Warning criteria winds might be on tap.  They're bad enough tonight as it is....

Worst probably ridges.  Nothing you can do... except shelter what you can and I would not be driving around casually later Sunday night-Monday in the ridge areas. High profile vehicles probably impacted.  Offline for a while.

This weekend will be our first cutter dropping under 970 mb with a -5 -AO. So the Southeast Ridge got so strong that it prevented the low from sliding to our south like in the past. Should at least be gusts over 50 mph and possibly 60 mph by Monday.

The block is very close to where it was for the other 15 times when the -AO reached -4.8 and lower going back to 1969. So it’s not too far north. The greatest difference is that there was no Southeast Ridge in the other dates. So suppression would have been a risk in the old days and not an intense cutter.

Factors other than ENSO ruled the roost this winter. There’s obviously been a huge, large scale change in the North Pacific, arctic and North Atlantic. It’s been a predominant -EPO/-WPO/+PNA/-NAO/-AO, cross-polar flow winter. The only thing missing was a strong, juiced STJ, if we had that, this probably would have been a historic, record breaking winter for both snow and cold, definitely rivaling, if not surpassing 95-96, 13-14 and 14-15

Yup, we wasted an opportunity in the snow department. The Nina background still had some lingering effects. So much for the climate change juiced up day after tomorrow storms that were supposed to become more frequent

Despite the snowfall frustrations here on the coast, at least this winter showed we can still get three consecutive below normal (with all caveats) winter months.   I would have bet aginst that prior to this winter for sure.

 

At least we saw a white Christmas and a few small events. It also has been cold. Icing on the cake will be a huge storm

The PV is currently splitting on the Euro. I don't get all the doom . We are tracking a potential big storm next week and another one at the end of the month. 

Like I said if we get 1 or 2 big storms , that would put alot of people above average. 

All the warm forecasts have busted so far this winter. It will eventually get warmer but not until March.
