They seem to think that CAD holds strong and keeps mixed precip to the south of DCA

Just a heads up, but that map is very very rudimentary and only takes into account what could be the predominant Ptype for the 24 period. That is also not an exact science. It’s a quick and dirty way to put precip forecast on the map. Typically used as a glance for public and people just wanting something very quick to look at which you would be surprised the higher level people that end up seeing that map.

Gotcha, thanks. Good to know it wasn't intended for scrutiny

We’re not in the jackpot zone but I’ll take the free room and unlimited  Alaskan crab legs buffet and $1000 free slot play.

Fixed.

And after your buffet and free slot play, you go outside and are surprised by 8 inches pow on the ground and a death band overhead that refuses to budge, and you are forced to stay overnight in the casino and that was how you ended up winning a 55,000 dollar jackpot AND got jackpotted by the HECS as well, after all.

That's the kind of winter you guys are gonna enjoy.

For the northern crew, remember the banding near the northern edge is always tighter and underdone. That huge area of light qpf will end up sharper and heavier until you hit the wall. Add in the higher ratios and this is just a generalization but if you are inside the .3 qpf heading into the final 24 hours you’re good. Outside that you risk the fringe.

Are you going to do live model analysis tonight and send out a link to join? Always enjoy that and it’s been a while since it was worthwhile. Either way, Happy New Year!

For the northern crew, going off the Euro only, things don't look as bad as some might portray. Surface temps are in the low 20's throughout but more importantly 850's are -8. Pretty reasonable to expect 15-18 to 1 ratios. As long as expectations are reasonable we're still very much in the game for 4-6 with the very strong possibility this nudges further north. If we get .3-.4 liquid were good to go. Accumulated snow still gets well into PA even on the south/dry runs. The upside is much better than the downside with this event in my opinion. Plus something like GFS is showing isn't completely out of the question.

Yeah. It is worth noting that the EPS only has 10:1 snowfall ratios.

Been reading for the last four days. I'm now convinced the closest analogue here is January 2010, roughly 2-3 weeks before Snowmageddon. 

People forget the number of storms we had in '09-'10. We got quite a bit of snow outside the three blizzards. This analogue isn't on Ray's storm archive because it didn't really reach NJ. But it was depicted by several models to blast NC and VA, leaving DC with a few Advisory-level inches--and while the former came true, the moisture shield spread much farther north than anticipated. I was working at SUBWAY in College Park as a senior in college, and I remember getting snowed in at work. We easily got 6-8" that day. 

The track and setup are very similar here. I'm betting the precip shield ends up blooming norther than depicted now, with a wider max stripe.

that would be sweet. Keep the Euro track but moisten up the northern edge up to Rt 30 in PA to around 0.4 or 0.5 liquid and everyone gets an easy win!

Just for the mental exercise and curiosity, I checked soundings on the euro for smith mtn lake area. I don't lose the column until 12z Monday and over .75 liquid falls.

Obviously grape nuts are hitting pretty good by 12z but sounding says all snow at 9z so idk? Am I going to back my way into this? Lol

Eta: just realized it's the 6z run. TT is slow lol. 12z prob stole all my snow

Our area really is all over on this one. I’ll also be curious to see how the CAD helps us. I’m up in Eagle Rock so I’m thinking we will see more snow than is being shown on the GFS

No you're not. In fact, you're wasting our time and your time, so beat it.

How you doing otherwise Bob?

Loving life man even if I get no snow. I'm interested in 12z soundings. I haven't looked at any really because I figured my fate was sealed mostly. My initial gut call some days ago was an inch b4 mixy mess with the boom scenario being 3" tops. Still probably a good call but my interest has gone up

I hope you know I was kidding. 

Great to hear.
