January Medium/Long Range: A snowy January ahead?

I'm so young I have zero idea what a good winter was like (except 15-16's winter storm jonas). Maybe I'm getting to witness what the winters of yore were like.

You don't have to go that far back. 2014-2015 was the GOAT. People talk about 09-10 but you can't make up for quality with quantity. 14-15 seemed like whole dmv was transported to new hampshire for two months. Lakes iced over into late march. actual snowpack. If we can get a persistent cold pattern out of the rest of January and into February it would go a long way in proving that 14-15 wasn't just some one off fluke

.5-.8 qpf falls south to north before we lose the mid levels on that scenario. 

Yeah…you can tell we score at least something there. I hate flipping (with a f’ing passion), but we ride the line and accept what happens.

It’s just really neat to see the obvious CAD on a view of the entire continent. Super geeky.

On that run we only briefly lose the surface and most of the heavy precip is gone by then. It’s a 4-8” thump snow to ice to a few hours of drizzle before the cold air freezes everything solid.  Old school we got those things more often. And they were great.

Does the pattern show any similarities to January 1994? Seriously doubt DCA goes below zero but ice storms we have not seen since then to that degree.

Yes. There isn’t that much difference between 1994 and 2014 and 2015 honestly.  There was another shorter comp period in Feb 1993 also.  Slight changes in the centering of the features lead to different results. 1994 the trough centered further west which is why it lead to more ice v snow. Even though even up here none of the storms were pure snow I’d love to repeat  that.  According to local coop data it was a string of 3-6” mix events that built a glacier. I remember that winter visiting my cousins in Harper’s ferry WV and they had a solid glacier on the ground all winter!  Fairfax ended up slightly too far south and unfortunate most storms were pure freezing rain.  
 

1993 was similar. 70 north got crushed and it was less favorable further south. again a further west trough axis. But it was really close. 
 

For now I like the axis of the features better, more like 2014 2015. But that’s something to watch out for. If the cold gets centered too far west it opens up the dreaded SER issue.

18z Euro AI now has the first wave next Moday/Tuesday as rain but the front sinks south and a second impulse comes north and probably drops 6"+ based on Dos style maps.
Again, AI jumps all around post 240hrs.

You beat me lol, yea it depends the speed of those shortwaves, we need to get a little lucky with the spacing as always

It’s basically a more aggressive and better spaced version of todays 12z gem

2014-15 was pretty good but 2013-14 was the real GOAT. The closest thing to a wall to wall winter that I’ve ever seen. Especially north of I-70.

After seeing @psuhoffman mention that J-F 2014 stretch as an analog to the possible upcoming pattern, I pulled up my accumulations from that season.  What a great winter that was for this area.

Honestly might have been confusing them. They were both great years. Feb 2015 was when I rode my bike over a frozen lake roland in college though. Will never forget
