Euro is looking reallllly juice at 216h. At first it looked like it would be a quick punch at 192h and then out to sea, but there's a second slug of moisture. Don't know how temps will evolve in this second system. The important thing to me is that we've had two GFS runs, two GEFS runs, and now the Euro all keying into some serious action starting in the 192h range.

I should've been more specific, I was talking about the signal for a storm being impressive, but I guess the GFS was the only impressive one. Euro is still strung out mess as mentioned.

Right, so maybe the lesson here is to let the run finish before commenting whether it is impressive or not.

Euro gives us a full day of ice in the second event, lol.

There's another theme from the last few days.  So 2 things are clear, strung-out mess and epic ice event, somewhere in the central or eastern US.  We'll know the details in another 10-15 euro runs, stay tuned  Tune back in later.

So the recap is 2-5" of snow with the southern zones winning that piece. Then over .5" of ice before frigid temps invade. I'm pretty good with that outcome. All frozen and would be remembered for a long time. Interested in what brand new and unique solution comes out in 12 hours. 

That's not a bad scenario, the ice saves us...though it's tough to realize prolonged ice in these parts.  We don't do CAD well.

I'd take that honestly. The ice part would be remembered for a while if happened like advertised

Very interesting.  Any indication of how much below freezing we are during the ice part?  I know it's perhaps a bit much to parse those details right now, but I was just curious, since ice potential has been a threat for this event all along in varying degrees.

Reminder that the couple 'perfect' solutions are likely not going to pan out and best to temper expectations. Pattern looks good for frozen but you can see many options are on the table. I dont see the consistency that some are touting on the models. Solutions like the CMC quick hitting SECS to GFS elongated train of snow HECS to Euro in several very different real-weather waves all on the table, to the JMA that phases out west and is a brief thump to rain to dry slot. It is going to be a roller coaster week. Ens the way to go for now. With that said, setup looks solid on GEPS and GEFS.....EPS should be fun to look at.

wx.graphics is stuck at D9-9.25, but when the (2nd?) storm gets going (which may be snow and not ice to start), surface temps are upper 10s and low 20s.

Changeover starts at 25 degrees, and then warps DC up to near 32, and in fact most of the region to near or below freezing

N and W burbs are pretty bad during Ice Stoms.  2013-2014 took quite a toll on the trees here. This storm would be rather serious even in the cities cause it starts supercold. Only good thing is we'll probably warm into the upper 40s once the wind shifts to the west, but the damage maybe done by that time.

Temps are great during ice onset. As depicted it would no doubt be the biggest ice storm we've seen in a long time. The second piece would have some snow and pl before going all zr so between the 2 waves it's a combo of every type of winter wx we can get. lol

Really bizarre evolution. Interesting end product though. 

Yeah, I guess (although I've been stuck at D9.25 for like 20 mins), but it's just too strange to give it any thought really.  I guess I'll take a positive that even such a screwy evolution gets us a memorable 3.5 day period.

Not sure I buy the west/cutter solutions though. Worst case maybe a slight move north before we see it Miller B to the coast.The models have been over playing the dump into the SW forcing ridging in front of the system. My biggest fear at this point is suppression and I am starting to feel a little better about that from what i am seeing on the runs.
