the problem is not me

I am analyzing a model run

I am the messenger

I am not worrying, I am not predicting, I am not whining, I am discussing a wx model, including predicted temps

if you folks can't handle that, not my problem

Mitch at 90 hours you appear to be in some pretty good precip. Your 850 temps are around -5. You have ne winds. There's no way the surface is more than 34 or so. I think you'd be just fine.

Here you go  4-8"  will about do it for I95 on this run.

That looks like a fair bit less than 4-8" along the I-95 corridor to my eyes, more like 2-4" with a sharp gradient before going into the much higher values to the west/northwest.  Not that it really matters to parse such things.

Wait until the NAM gets a hold of this lol....If the GFS is showing 2-3" of QPF imagine the NAM. 

 

Bit OT but right now I am 75% sure I will make a roadtrip for this storm since it will be the last chance to see snow most likely this year.. What is a good spot in NW VA that has some elevation and does well usually? 

Try 522 S of Front Royal.  Easy hwy access and 2000+ elevation crossing Chester's Gap.  In marginal temp events the 8 mile drive from Front Royal feels like you've driven to another world.  Dec 5 2009 there was about 4 sloppy inches in town and I drove up to Chester's Gap where the snow was mid-shin deep.

Yeah I really can't see DC getting only 2 inches with this storm track and amount of precip. That snowfall map only shows 2-4 (dark green)for 95 not 4-8, but I don't believe that. 

 

They're called clown maps for a reason ;)

I don't think we disagree...I guess my point is to not worry too hard about specifics this far out since things can change in a hurry when it's marginal. I understand fully how tough it is to get a HECS there. You still have some issues to work out at H5 over New England and energy diving into this trough from the Plains too...nevermind where the deformation band sets up.

I know you're not but a lot of people see 1" on the model and assume that's great. But if it comes over 24 hours its probably not. Now is not the time to punt or anything but its waaaaay premature to be declaring victory as well.

That's what I was wondering, to my eye it "only" shows ~2-4" with an extreme gradient just to the west into the higher totals.  As I said before, maybe pointless to parse those details on that kind of map now, but I did also wonder.  How much of BL temperatures are taken into account on those, and what ratios are typically used?

Can I STFU to everyone in DC north area? Serious--

 

You guys had 3 KU's in 09-10. Yeah, it's sucked balls since then. So what-- it's snow. We had a couple decent events down my way since then, but nothing to make up for those 10 days. I had 36 inches TOTAL that winter. 

 

Grow up-- I'm sitting on the fringe-- w/luck I can see 8 inches, 4-5 more likely due to ratio and crap.

the evolution of this has continued to and will continue to change. The pseudo 50/50 low and whether a piece hangs back or not is still not resolved. Also, the possibility of phasing is becoming more evident on 0z vs 18z (look at 78 vs 84 hrs and the vorticity that is thru the central plains).

 

I don't think I've ever seen global's print out that amount of QPF this far out. This a ridiculously dynamic storm and could be record breaking for someone.

I am. We only get HECS around here. HECS are easy. Its the 3-6, 4-8 storms that we can never get

Ive been chuckling and lol'ing at your posts since I joined eastern in 2005 and they will never get old. Ha

Jokes aside, were getting awful close to feelin "ok" about a march caliber hecs for all. Including Mitch even though he changed his name to Deb.

all bets are off if theres a significant phase with northern stream.

Sounds like you'll be hitching the ole pop-up trailer to the back of the Prius and setting up camp on the windward side of Beacon Hill! You can find it via RadarScope; it's the annoying, intransient 20dbz anomaly about 10nm WNW, and a lofty 250' above, LWX.

Let's wait and see what the Euro shows.  We are still 8-10" on this run of the GFS.  And this snow map looks much more like 12z Euro but just a little north.  Maybe GFS is still playing catch up.  Crossing my fingers but going to bed.  It will be a long few days.

HECS to me is 18"+, term is way overused by some here.
