Here's a panel from the jan blizzard. Trough is negative and the upper level low is closed off. This is what a big storm looks like in the upper levels.

Scrolling quickly along I almost fainted thinking a model put out this solution.. Then I figured it out.. Lol

Awesome. I also heard that Atlanta on the 10 day mean has 2 to 4 inches of snow , which I believe is unheard of .

Have you ever seen that Bob?

Hard to say. I never look that far south. lol. I don't see the 2-4 down there though. The 2" line cuts NC in half through d13. 1.5+/- in ATL. 

Euro control hits NC and our area good though. I can get behind that. Would be great for the MA and SE crew to share a good event.

Thanks again. An exciting look for sure.

A lot of snow cover can be put down in a pattern such as the Euro is showing.   

Hopefully this time the blocking  materializes

Atlantic block starts forming inside of 5 days so that's not a fantasy. It's pretty much reality at this point. We just need to be in the cross hairs with a wave running the boundary. We won't really have a good idea on that for 5-7 days unfortunately. It's going to be a roller coaster in here for sure the rest of the week.

Never ceases to amaze me just how hard it is to get it to snow here, lol So we can even have a very good setup like the one you just posted a picture of...yet we still need things to track a certain way, right? Lol

Nah, shouldn't amaze anyone. MA climo isn't very snowy. Mean snowfall is made up of boom and bust so sucking happens way more often than winning. Generally we probably need 3-4 chances for each actual event. This is only our second one so far. Wasting good setups is something we do well. lol

100% agree with Bob. At least the projected setup being shown gives us hope.

Does anyone know what the EPS control verification is. How does it compare to the model run.

Expand  

Need dtk to chime in, but I believe the control is initialized exactly like the op but run at ensemble resolution. So no reason to think it's really superior to either the ensemble mean or the op. The control got a lot of cache once upon a time when it sniffed out a big storm before the op. Can't remember which one...

Days 10-11 on EPS look so sweet at h5- nice ridge poking westward into GL, and trough at 50-50.

Expand  

Have we ever seen a perfectly modeled snow event 10 days out actually work out?  I want to believe that we can track this for 10 days and then cash in. But I know better.  Although last year we had quite a lead time.  6 days I think and it trended better each run.
