No signs of life for the day 7-8 threat on 0Z Euro?  I see a 984 low over eastern Mass, wondering how it got there.  

There is a storm. Verbatim its rain in our region. Too much low pressure up north. Just about all the ens members have a NS low for that period. As modeled its going to be a problem.

Thanks for the response.  I know I shouldn't ask IMBY questions but judging by free maps it looks like the ridges in WV/PA/MD have a shot at something as the low passes or at the very least it looks like maybe a favorable upslope set up during the CAA after it passes.  Trying to decide whether or not to plan a trip up to Canaan for presidents weekend.  Can you shed any light on what the Euro shows for this area?

Verbatim on the 0z Euro op, Canaan would get snow with that storm and in its wake. Fwiw, the accumulated snow for that area is about a foot at day 8. That would include whatever fell last night/this morning.

Psu-  thoughts on this rolling into a decent look? Potential to for the West Coast trough swinging east and maybe those higher heights back in the nao space? 

Need something to discuss post today's debacle ughhh

you forgot to add this gem....the accompanying 850 temp anomalies     lol

There is still potential for late next week, but there is just so much NS energy its pretty easy to come up with all the ways it wont work. Beyond that, as someone posted above, heights do build but it looks transient and the advertised pattern gets pretty decent again. As Bob mentioned yesterday, its close to a late winter 2014/15 look, with a big EPO ridge. GEFS looks better than the EPS but similar idea. Question is how much cold does it tap up top and send down our way.

We're getting into the range where I'll start to look at specifics and those specifics suck right now as noted above. But the overall mean pattern is a loaded one and some small adjustments in the timing of the northern stream energy and suddenly we have a storm. I see two ways this could work. Either get the northern stream system that dives in right ahead of the stj to either speed up and get out of the way or slow down and become a possible phase. After that we could get a northern wave to dive into the trough as it's loaded and ready to pop anything for a couple days.  I'm disappointed in the look of the details right now but given the pattern they could change.  Then things relax for a few days. 

After that it appears the nao breaks down and I fount it's a coincidence that happens as the mjo fades. The question is does the epo take over enough to hold the trough in the east. If it does we're looking at an arctic connection and this time of year that can work well. The gefs says YES. EPS says maybe. Geps says no.

very interesting quote from joe d'aleo of weatherbell from his update today regarding east coast storms in the next 10 days as he was talking about

BTW, if this i MJO triggered, the phase 7 we are entering is a wet pattern northeast but phase 8 dry and cold northeast and phase 1 wet Mid Attlantic and cold in the east.

I'd post it if I could clear my dumb attachments folder but click through the 6z GEFS low location panels on wxbell. That late threat looks really good at range. It's a very 2014 or 15 type of storm progression. Departing 50/50 / good trough alignment / +NAO / nice shortwave rounding the base.

Oh, i tired to see if I could do a mass clearing...I can't :(

Yea that late window on the gefs looks classic. Nao breaks down. Epo ridge. Departing 50/50. A lot to like. The EPS is less ideal but it's close enough to think the gefs has validity. Plus the EPS has been very bigly overdoing the progression of the ridging into the east. Go back a week and it had a torch for when out day 7 threat is. The gefs was the first to see the trough in the east there.

If anybody is looking for wx porn in the wake of the recent disaster...loop the 6z para starting @ hr192. Nice dance move. Like a pole dance but in a weather kinda of way...lol. With a happy ending. 

Haha, that's perhaps quite an apt description!  I saw what you're talking about in the 06Z Para...another solution, another possibility I suppose, but a good one!  The 2-m temperatures and the precip type plots on TT looked a bit wonky given how good the mid and upper levels appeared, but at this stage out, I guess those details don't much matter.

Love when you talk dirty. 

There have been a few nice solutions mixed in run to run to keep the period as a legit threat.  This is way too nice an overall look to say no chance. Yes nitpicking the northern stream is in the way but that can change in 6 days and then this look is great.  Plus even if it does phase late it sets up another chance a few days later as the nao breaks down.
