Late February 2013 Mid-Long Range Discussion

I was thinking how ironic it was in the last two plains blizzards that we needed the 500 lows to come further east, but they ran to about Missouri and hit a brick wall.  When we need one to slow a bit, it's a steam roller.  I've come to agree with you about north vs west trends.

yea, there are two different issues with this, the h5 track, and how quickly the surface low amplifies.  The two are not completely independent, as we need the more phased solution to get the better surface low solution.  Even if the h5 takes a perfect track if the surface low develops late we are screwed.  I guess from my experience, getting the storm to amplify in time in these types of situations is the bigger problem versus getting it to track over us.  I am not saying I have confidence this won't miss us to the north or south, just that I would rather see it nice and amped up and then take our chances on the track, then be needing the right track and worrying about if the storm will even develop in time.

....Has anyone learned about disregarding the Euro this winter? It has been far better than the GFS for most events this year. Every time the GFS shows snow, it's hugged, and it turns out to be wrong. And now it doesn't show snow, and it's still hugged? I'm leaning Euro on this one, just due to it's track record this year.

Good primer since no one here has followed the models this winter

Of course he's saying that. He's wedded to the euro solution. I'd go with the gfs here. I'm always weary of a+b+c needs to happen events

mountain highs and valley lows. But i think we are in death valley. I havent had a mountain high since 2011

I don't know that I necessarily believe the Euro, but I do agree with your statement. Everyone says, "What does the Euro say" when the GFS and NAM give us snow. When it's the other way around, the Euro isn't trusted. Weird crowd.

I dont have the KU book handy, but I can't think of a storm with an ULL low that takes the GFS track and gives us a snowstorm...every time we got a snowstorm with that track, the northern stream dove in and pulled the ULL somewhere into eastern TN/SW Va before it could progress any further southeast

 

GFS was kinda wrapped up this time with the ull even without a phase. We have such a long ways to go here. The closed ull to our ne will not be in the same spot or even close to the same spot as shown. Sure it's possible it could be a perfect modeled location but it would be be accident. 

 

I'm sure we'll be getting sucked in and gut punched a half dozen times but it's just another solution at a long lead that won't happen as shown. I would hedge on a further nw solution but still plenty of opportunity for a big whiff even with that.

Social Media Feedback Loop:

 

1) Find 8-day forecast of east coast storm

2) Post snowfall map

 

3) 8 days later (verification time)

  if snowstorm verifies then

   "Post on facebook noting your heroic forecast with an 8-day lead time" ....collect more followers

  endif

  if snowstorm doesn't verify then

   "Post on facebook that is was just one model solution---tell followers it was never your actual forecast"

  endif

 

4) Rinse and repeat

Exact formaula. I am patenting it!

euro is bouncing around it seems mainly. not sure there are any trends there.

 

0z night before last was a NW of 95 event into WV, 12z yday was a Cape May paster, 0z last night crushed ROA.

I agree, I think the euro is definitely hitting the more phased solution between the lakes h5 low and the manitoba low, but other then that its bouncing around with the exact track and amplification of the surface low.

the GFS runs are getting worse and worse

GFS is not budging with its solution of not phasing, for that matter it has the UKMET in its camp also.  If the h5 low diving into the trough does not phase, there is no way its going to get the job done because the flow will remain suppressive with where the block is and the old dying new england low not getting out of the way in time.  GGEM is off on is own planet right now with its solution, and the euro seems like its locked into a totally different evolution at H5 phasing the two streams very early on thus allowing a more amplified system.  Usually I would feel better with the euro having 3 runs in a row with the phase, but this year the GFS has been schooling the Euro in the 5-10 day range with the one exception of the CT snowbomb.

yeah, i think the last three runs are more or less in the same type of camp.. specifics are tricky. tho it is still a week out so they should be...

agreed, we need the h5 phased solution of the euro to be right, then hope for luck with the track.  THe GFS evolution, we would need to get really lucky to have that work out.  I know it seems close, but looking at the h5 I just dont see how that is going to overcome the suppressive flow without a more phased solution between the two h5 lows.

Maybe the GFS solution isnt bad since it will probably trend north...The last thing we need is something that flushes us and the ULL ends up north of its modeled solution..1/22/05, 12/30/00

I think a lot is likely to change in how this sytem evolves, but given the h5 setup on the GFS I just dont see how that could end up a snowstorm for our area.  The flow is downright hostile without the phase.
