Oh I know my friend, that's actually the one I've been keeping a keen eye on because I have to drive to the Poconos that day.  Looks downright treacherous with that low level cold refusing to budge until late in the act, really hoping for a Euro coastal look.  My plans may have to change, especially given what we saw in that horrendous video out of Fort Worth.  Man that was tough to watch, never seen anything quite like it. 

Nasty crash. i've been on some multi vehicle doozeys on I-81, but nothing like that, wow

I think next week is going to be fun one way or another. Have fun and dream that the EURO is perfect for us. I will miss it to, I have a 1:00 meeting. Bubbler it is all on you.

PSU just had a few longer posts on the MA LR thread and has shut it down for 50 min now.  He must not have read the room right.

Never like seeing the cold and snow down into Texas like that. Usually does not work out well for us..

Yea, I've been considering that aspect. Typically an amplification as major as one taking extreme winter weather pretty much to old Mexico and the Gulf Coast generally wouldn't bode well for us in the eastern US but we still have the sprawling high pressure and the cold air to the north and the low attacking it from the Gulf. Majority of guidance and ensembles keep this surface low below us, initially on the west side of the Apps in the SE but eventually going to the Mid-Atlantic coast. Not a wound up deep low either. So this is definitely looking like a pretty high impact winter storm for C-PA, but details on P-type are anyone's guess really at this point. I still personally prefer more frozen (snow/sleet) solutions, like the GFS. Should note there is a huge difference in surface temps GFS vs Euro (8-10ºF) during the height of this. Even with that, I don't really buy the Euro's expansive ZR, especially outside of the southern tier where the column would suggest sleet more than ZR.  

Why do I prefer the colder solutions? Despite the core of the arctic air not pushing into our region, it slides east across Ontario and Quebec with that sprawling high pressure. So I think surface/low level cold is going to bleed down into PA pretty efficiently, especially with the majority of guidance keeping the surface low underneath us. It seems that 700-850mb zone is most likely region this busts above 0ºC and that's high enough in the column that i'd be considering sleet as predominant mix over ZR, although there's going to be a stripe of more significant ZR to deal with somewhere as well.. and our southern tier near the Mason-Dixon is a place to watch for that possibility .

To me, and as a number of you have mentioned, by far the biggest story of the pattern is the inability of the truly arctic air centered over the central part of the country to bleed its way east.  I mean, considering what all the models were advertising for most of the past week it's pretty stunning to see where things are heading.  Disappointing really, as I was looking forward to some icebox temps, to say nothing of the fact that snow is likely off the table for most of the LSV now as well.  Not giving up yet but trends are less than ideal.

I'll gladly take the milder temps and active storm track we have right now over having the extreme cold. Especially since we are still cold enough to mostly maintain the pack that's on the ground. We've had conflicting signals via the teleconnections for a lot of this exceptional NAO/AO blocking period with a mostly -PNA and a solid MJO magnitude that's been floating in the Phase 6-7 region. (currently 7) 

Want to know what they usually translate to, especially in 6? Not going to get into a whole thing and stat lesson on the significance % maps but regions in that blue or purple shows high correlation to the temperature pattern. That's why phases 4-6 are frowned upon greatly in the eastern US, esp during a Nina. Phase 7 is a warm phase in the east too, but not as strongly. But the gradient pattern we're in and the arctic air not completely dropping in to the east makes alot of sense when this is considered. I think it's a blessing in disguise personally. You don't have such strong NAO/AO blocking then you guys are talking about still having the AC on. You don't have the conflicting MJO signal and it's conceivable its frigid in PA and we're lamenting DC and VA getting all the snow. And I guarantee you guys wouldn't be so disappointed we're missing out on it being -10 if that happened.

I’ll take sleet ice or rain all day before -10 and dry.
