Euro is going to be too warm in the mids for the d8+ potential. It's more of an ice setup than good snow. However, considering the significant changes we just saw for d5'ish, confidence beyond that is even lower than it's been. 

Yep.  OP guidance is basically unanimous that there will be a storm in that time period.  That’s good enough for now.

lol- it's HEAVY zr. Haven't seen a panel like this for a long time

Extremely disappointing run

I don't think the run means anything other than the period still has a storm coming up from the south. Look what just happened with D5. We don't know a damn thing right now about what may or may not happen.

I'm looking at the not very detailed maps on TT and see what you're saying on the 850s.  The 00Z also has us losing the mids with what looks like a primary that tracks west of us and never totally dissipates in favor of the coastal.  Similar thing to what the new 12Z shows, I guess...again, going off the limited detail on TT...but 12Z shows more coastal perhaps, and the high appears  more entrenched too.  Now, I don't know if 00Z also had us in more of a mix or ZR vs. snow, but at any rate obviously dissecting such details this far out is not worth it.  Just trying to see differences, etc.  Like you mentioned (in a slightly later post below), a ton of ice is probably not the most likely scenario here, but verbatim would be interesting.  And it shows just how strong that high is even if the mid levels get bullied out.

The GEFS was basically split down the middle between snow and mixed/rain for D8. Both options are clearly on the table. I expect the EPS to be equally split. Now that next weekend has completely changed its personality it gets extremely muddy beyond that. It's not a big storm pattern or an easy long track pattern. Expecting ops to lock in on anything specific and hold for days is completely unrealistic.

As the new regime is just starting to take shape, i'd personally not get to wrapped up in finer details yet.  Euro just gave a major change to med range guidance.  I'd track the storm for now, and by Wed/Thurs start figuring out R/S line.

I actually like DT more than most. Us eagles fans have to stick together. But right now he is full tilt off the rails and someone needs to give him a hard time to shock him back to reality. 

Agreed about the eagles thing. But when you start bashing hobbyists and implying he is the be all end all of LR forecasting and everyone else including "Twitter freaks" are clueless and "full of shit" I'm pretty sure many folks take offense to that. Yes he knows atmospheric science but tone it down and eat some humble pie for a change. We r all right at times and we are all wrong at times.

I know...and I'm certainly not wrapped up in fine details like that (though perhaps that post sounded as if I were!).  Mostly was just taken aback by that crazy ZR plot Bob showed, gotta admit that was rather incredible even if silly to consider right now!  And yes, there were some serious changes.

Up next is to see whether the mean snowfall trends on the EPS continue to improve or take a step back.  

As for the ice on the Euro without question could trend colder and be all snow.  But I prefer no ice storm.  

Perception and damage wise a significant ice storm leaves a nasty memory about the winter being possibly worse than it was. However I can see why because they are dangerous to both person and property. I dont want to spend 1500 right now on my scott pine to take her down.

I doubt we see that kind of ice in the end that the Euro depicts, but that was some impressive "digital ice" to be sure!  My main take-away is that there is a storm with a fair bit of moisture, and plenty of at least low-level cold air nearby.

I was in a bad ice storm in Atlanta years ago...around Jan. 2000 as I recall.  And yeah, pine trees and ice are a bad combo.  The oaks and maples, etc. were generally fine but all the pines and magnolia trees got shredded in that event.  Large magnolia leaves plus 1/4-1/2" ice equals disaster for that tree.

I don't understand some of these replies basically locking in an ice storm 8 days away lol. Would you lock in a snowstorm if it showed that? My take away from the models today is that chances are increasing for at least a light wintry event this weekend and then a bigger storm next week with details completely uncertain. That's the reality.

If that Euro map is rain at 30-32 then ....well...look out your window...nothing to see folks

Yea if u want a good (or bad because of the damage) ice storm you need temps in the mid to upper 20s with light to moderate rain over a long period.  Moderate rain at 31 degrees especially during the day is just cold rain

Mid to upper 20's everywhere as the heavy precip moves in and below freezing for a while before that too.  Already a few tenths prior to the panel I posted. Like I said before I'll always take the under on legit ice. Verbatim the Euro is a damaging ice storm though.

I wouldn't agree with this.  I think a lot of us today have seen a little freezing rain then a lot of 33 degree rain.  Speaking of ice storms though, I experienced 2 really bad ones living in northern Louisiana in December 1999, then again in December 2000.  We lived in the woods about 30 miles south of the Arkansas border and it was solid pine trees.  I just remember sitting out on our porch watching the sky light up green from transformers blowing and hearing the pop and crash of pine trees snapping all around throughout the night.  The trees would snap off halfway and the bottom part of the trunk that was still attached would swing wildly back and forth.  The damage to the trees was like a slow motion hurricane.  We lost power for 8 days in 1999 and 9 days in 2000.  The town that we lived near (Ruston) was 100% without power.  Those were some of the craziest weather memories I have.  I was only 9-10 years old and didn't record any video...I so wish I would have.

Looks like EPS took the proverbial step back for next week’s storm.  At least in terms of mean snowfall.  Shaved about 1.5” off the mean.  

Edit: As Bob pointed out, much of that reduction is from today’s storm.
