Central PA - Winter 2020/2021

also to add to above, the GFSs late handoff would present thermal issues into same areas that saw them today, as lover levels would warm while waiting for secondary to pop.  The "others" would not present that worry as SLP stay under and East saving our precious thermals.

the transfer on the GFS looks much less appealing when one looks at the ICON/Euro and even CMC.

In my mind, GFS oozes dryslot w/ spacing issues it shows.  That's all I'm getting at.  The "others" just look more clean and consolidated (even though a bit wonky and strung out).  In my eyes its the GFS holding the primary longer that makes it look less appetizing.  Plenty more runs to decipher, but hey....we're trackin.

We gotta get the WAA precip with the primary to us and then get the transfer going, basically what the GFS does on the front end but get a transfer positioned like the Canadian. The Euro evolution drops it under us when it transfers to the secondary all the way in GA/SC. I mean yea it does catch the LSV below the turnpike pretty good in the end but I'm def not rooting for forum splitters.

Early looks of the Euro ensemble looked good, there's several big PA hits in it.

Im no Mag, but yes.  GFS was ugly and strung out.  Euro was nice transfer (earlier than prior runs), and then pops and stalls off VA coast.  

We need the GFS to weaken primary in upcoming runs and go to the ICON/Euro looks.  Not sure where i'd place money right now, but I know where i wanna....

Thanks Nut.

Euro primary's on a trajectory notably south of the GFS and definitely slower. It gets secondary going all the way down in GA/SC that arcs up to VA Beach. Energy phases and it hangs the low right around there before fading out. The low's in an okay spot for us where it hangs but the way it get's there probably limits precip extent into our neck of the woods. 

The GFS isn't really that bad, it was pretty close but a bit late on the secondary and the primary comes across the country higher. Canadian tracks more similar to the Euro but like mentioned  above the Euro has the secondary going the whole way from the SE while Canadian transfers a weaker low from the Oh Valley to the Delmarva. The Euro basically just put up the ideal way to bury DC/Northern VA with it's 12z op run. 

Thanks Mag.

Yes thanks everyone for their input and keeping this forum flowing.

12z Euro transferred earlier which helped greatly IMO.  EPS control is just NSFW (compared to what we've been seeing of late).  

Takeaways are we've got ducks on the friggin pond again....and a big honkin goose as well.  Who's gonna cave?  I think Mag nailed it when you look at 500's and ridging out west.  it makes a big difference here in the east and todays runs are starting to see that.  Chips slide to the foreign/Northern models.  

 

Onto happy hour.

Cheers! Good 12z runs. Let's get HH to follow.

I haven’t been outside all day but I figured the driveway was just some slush to push off. Nope.. what a mess. Another winter day at the ice kingdom. Temps are still near freezing.

Thats what i was hoping we'd get for this "event".  Got ice skates??

[pasnownut]

BTW, verbatim the Euro shows the LSV snowing basically from 144- 178 (spitballing 6hr panels).  

Even if that only amounts to a shovelable snowfall.....I'm down w/ that.

Me too and this far out I like it. 

[paweather]

We knew if the ICON showed it others would follow. 

[pawatch]

Mag I thought it was going to just be some loose sleet. Have 1/2" of solid ice. 32 degrees here.

Euro is something to watch...alot of runs to come.

Well.. happy hour GFS definitely on board with the capture & stall/prolonged event idea.

Eastern PA bullseye of over 1' in some areas. Heads up, @Voyager! 

Every time I see that picture in your Avatar I smile. I had a dog growing up that was a carbon copy of yours.  

[Ahoff]

I just want to see a few inches in my area. Some of those maps posted are horrendous for me.

Eastern PA is close to 2'.  But, MDT gets 16" and YOU get 18-20" while I get only 8"...lol.  The map is very weird with distribution. But, you also missed 25" in central Lebanon County.

Nice tick in the right direction and a couple moves away from a whopper. Primary dies a bit quicker death and once secondary pops it comes up and stalls then crawls up and out. Verbatim it also shows a prolonged event with approx around 48 hrs of snow.

You are correct - I downplayed it a bit not to cause undo excitement amongst us weenies.  

It's going to be an interesting several days upcoming for sure.

Wow. I didn’t look at color maps. Just 500s and surface. 
Good to see it coming in line. This might actually happen.

Here is that colorful snow map from the 18z GFS! CTP bullseye!

The Euro is right where we want it at this range.

Here we go again... maybe this is the one?!?

Haha.  That total forecast comes to a range of 112-144" in less than 72 hours!

[Blizzard of 93]

The 18z EPS has a great look for the early week snow chance. The end of the 144 hour run has a great cluster of lows off of the coast of NC up towards the DelMarVa. The High is anchored over Quebec.

There look to be a range from inland runners, coastal huggers to some off of the coast. This look should only improve as the few eastern outliers are reduced as the event nears.
I really like where we are sitting for this event. Only 5 days to go until the storm gets underway in our region.

Maybe this is the one?!?!

Nice post. That low cluster to the western side still would be great for many inland and ok here in LSV although more taint possible. Cluster just off the Chesapeake bay seams reasonable  given spread shown.

That's a possible outcome, but to give particulars 5 days out is ballsy. Better to say "there's a chance of a significant winter storm" and start adding precip types in the next few days and potential amounts starting 24-48 hours out.
