December 2020 General Discussions & Observations Thread
Allsnow replied to bluewave's topic in New York City Metro
I remember saying after the 10th things will get better. It’s up in the air on how long that lasts. As of now, it looks like Niña pattern will return towards the 20th. -

Is that from the op run? The GEFS are +3. A lot of that is from the warm up next weekend as the pac reshuffles. -

We will have a shot a something the week of the 13th. The pattern looks to get more hostile/Niña like by the 20th -

Weeklies have the cold shot and snow potential December 13-20th. It then goes full on Niña with cold west/warm East. Around January 15th (la la la land) it has -nao, -epo, and cold moving east. Looks like a niño pattern in the middle of January -
It comes down to when the phasing occurs. If it’s late you can certainly get this outcome. Looking at the idv members of the eps a good amount had nothing. The general theme was big hit or nothing. Really nothing in between

I do agree, it’s a great point by you, any airmass other then we had prior to this system probably would have made things more interesting.

Yep, +pna was to west to East. We need to have had it more poleward. The rest of the ingredients are there, unfortunately.

This just shows the importance of a good PNA ridge out west for snow opportunities

Dec 5/6th major coastal/ west Atlantic cyclogenesis ...?
Allsnow replied to Typhoon Tip's topic in New England
Yeah. You’re seeing the American guidance coming back towards a more zonked solution. The euro might have been all over the place but it was the first to show such a dynamic system. -
Great post. I think the northern shore of LI should watch also

If it goes ballistic just east of sne, LI could get into some CCB action.

All we are blocking with this set up is pac puke. Basically killing the snow potential

The ensembles did a good job of predicting the ridge in west and trough in the east this weekend. It’s just small details that we won’t know until closer in. This weekend we have a nice 50/50 Feature that wasn’t their earlier. -

One of the reasons this storm is trending snowier for interior areas is the 50/50 feature that was not expected earlier. Instead of a ridge east of main it’s north of that area. The only reason this isn’t snow for the entire area is because the pna ridge is to flat. This is just another example of having bad luck in a small window of opportunity
