Whats interesting on 12z  for PD was the NS and SJ almost phased but the block was too  strong and squished it all.   Had block  been any weaker may have turned out pretty nice.  Still time. 

The 12z Euro is also very close, and we still have PLENTY of time. Verbatim it brings snow up to central and eastern NC and far SE VA. We really don't want to be in the bullseye this far out, I'd prefer the storm stay south on the models then trend north over time.

So, looking at the EPS, I can identify the 18th-20th and the 23rd to 25th as the second threat. There are not many good snow hits for our region, and there are quite a few rainy members. I looked at places like PHL and NYC during this time frame, and some of the ensemble members have them performing very well, so there is still an outcome too far north on the table. My confidence at this time still needs to improve on whether or not this pattern will produce a satisfactory result. But it can still change in the coming days.

The snowfall mean on the 18z GEFS was lower than 12z because of fewer hits.

But, interestingly, there was one ensemble member (p09 below) that obliterated SE VA and NE NC. It looks like March 1-2, 1980. I cropped it below for a closer look, if only something like this could actually happen. B)

It’s funny though when the gfs shows snow every third model run or so we don’t believe it which is fine. But it’s too early for 2/18-19 to automatically think too warm or too suppressed will happen either. Everything is still on the table. days out.

The CMC is the closest to what the Euro showed at 12z.

As I mentioned the other day, there are two opportunities. The 00z GFS and Euro had a rainstorm for around PD and the 12z Euro has already advertised a more southern and colder solution for us so more confidence is needed before taking anything too seriously. Then we'll see how the second threat around evolves in the coming days.

The 12z GEFS had a handful of hits, including another member (p10) that obliterates our area February 23rd-24th. Overall the GEFS was a nice improvement over yesterday's runs, but there is still a lot of spread. I don't know if we should give up on the winter with these signals.

Today's 12z EPS maps are the best we've seen before the mid-January threats. It's been frustrating, for sure, so we'll see. But, there is still a decent signal for the 17th-25th.

Probably too soon to say though. Surface maps not good but 7+ days out are virtually meaningless. 

still no sign of  winter at  18z

 

JB remains  optimistic though how  can winter  come  back when it  never got  here?
