getting closer to the 6" mark at Hyner Mtn area

more than me up here, have at least an inch of sleet and about 2 of snow.  We had all sleet with a little zr till about 1 then it switched over to all snow, but the precipitation was lacking.  Unless the radar really starts filling in over night this is going to be a pretty big bust on the wsw 6-12 we had this morning.

As far as event totals, I had about 1.7” of total frozen…basically 1.6” of sleet and a skiff of wet snow on top. Ice accums were negligible after it touched above freezing with surface temps but I think I had roughly a tenth of so of that this morning. 

The lull in the precip this afternoon definitely affected the overall outcome by coming to this area at a time when precip was getting ready to turn to snow and/or reach prolific pinger event status. The secondary batch mostly went just east of here. The result is a bit of a bust, but that much sleet is still a good bit to deal with. And it will have staying power with a cool forecast from here on til whatever happens near Christmas

18z GFS/GEFS and Euro are all good for a plowable snowfall for much of this subforum towards the end of next week. Behind that, strong consensus for below normal temps and a weather pattern favorable for additional storms. Couple of caveats worth noting:

1.) IMO, I would focus more on ensemble guidance until 00z Tuesday. After that, put more weight on operational guidance.

2.) We're looking at al almost El Nino like pattern in a La Nina pattern. Weird things can happen.

3.) I don't think this turns into a MECS or HECS, the ceiling for this seems SECS. That being said, this would be Christmas snow with deep cold after it and put many places at or above climo for December. It's a solid pattern that we are entering!

Love seeing someone post from the northern tier. We need more of that God’s Country representation!  What is your elevation?

Is it wave spacing, the fast flow, unlikely "perfect" phase, geographic location, or something else that would make you say the ceiling is a SECS?

sorry to hear that.  Yeah that warm nose often tends to be a spoiler in systems w/ marginal column.  Warm so often seems to win. 

Lets get some blue lines below Pa for a few days n see what next week cooks up precip wise.

Plenty of Mec/Hec on the ensemble members.  The eps ensembles use slightly different starting points (except the control I believe) to cover many options but with so many showing at least a mecs, probably suggests the ceiling allows it.  The perfect phase issue makes the floor a bit lower as well.

How bout all the above?

In something like the HH GFS run wave spacing is close enough to almost work together (northern stream and southern streams phase).  As I suggested earlier, the northern stream (NS) energy is diving in on the back side feeding the coastal storm cold air.

The pattern depicted is not progressive (fast), and the SLP off the coast takes its good ol time coming up the coast and gives time for that NS energy to catch up and "dives in" on the back and bombs out off the coast.  IF that would happen, thats called a capture/phase as one system feeds into the other (NS dives into SS (SLP off coast). 

The excitement is seeing all pieces of the puzzle getting close to working in concert w/ one another.  I'll not go much deeper than that cause thats the pros job, but hopefully my info in weenie terms helps to understand the elevated excitement. 

Thats how I see it and if any disagree or have better disco to offer....share away.

All that said, Eskimos right, its a long ways out, and there's a bunch of good and bad runs likely to follow...so keep expectations reasonable.  It's also been a long time since something like this has shown up inside 240 hours, so a tad of excitement is totally warranted IMO.  I'm keeping a casual eye on it, and wont dive this deep on every run...too far out.

This is a pattern we haven’t seen n years

I agree, it is good to keep expectations reasonable for now….but this pattern next week has the potential to be a major storm just before Christmas that we remember for a long time.

At the very least, we have a very high chance of seeing a white Christmas even if we just get a lower impact event next week.

alright blizz....if your power goes back out.....turn on the generator....you were slackin today and the night shift belongs to you buddy boy.

Go find us some snow.  

 

Lol, it’s probably good that I wasn’t able to post much today. i will be better off in the long run with a little extra rest!

I have the feeling that that there will be many long nights of tracking this week!
