GFS made a nice shift towards a more amplified shortwave for early next week

this may lead to snowfall from the shortwave in focus, but this also will lead to more confluence for the wave over the SW US

one of these two waves is our next legit threat IMO. the stronger the first one is, the better. could lead to two storms instead of none

We obviously haven’t produced here, but I think the guidance has done well identifying significant lows at range all winter. Someone will get a legit event.

Since November 1st how many images have you posted? And how many of those images have verified????

Heres an idea. Go to school. Get the degree. Dedicate your life to a passion. Study it. Get to actually know it. 

Can't do that? Don't want to? Don't have the wherewithal for it? Fine. We all have our gifts. We all have our strengths. But don't attack someone else's strengths because you're frustrated over this winter and want someone to blame instead of taking the time to understand an expert who volunteers their time for your benefit. 

Oh and.. Maybe read your posts before hitting submit. Even the least educated of a group (I am specifically referring to meteorology here) is unknown when they remain silent on a subject they know little about.

Correct.

This sort of GGEM/GFS ( and they are not incredibly different considering the time range + synoptic parameters ) look may in fact be some sort of primitive attempt at an early consensus.

The models are attempting to simultaneously evolve a New Jersey model bomb - the old amplifying clipper routine - but having to conserve a very fast velocity base-line flow, that is actually a neg interference.  question is, does this or can this slow down on their getting into the 965-975 range upon exit.

I'm not the least bit frustrated with this winter.  Heading into this winter I had exceedingly low expectations.

the system around the end of the month is probably our next legitimate threat. there is relatively high confidence on there being both a vigorous S/W moving through the Plains as well as a strong 50/50 in place to establish confluence. the -NAO itself isn't established, so the longevity of the 50/50 is a bit tenuous, but it may be very strong and do the job. this might be a NAO phase change event, which does lend itself to more dynamic solutions

multiple members of the GEFS and GEPS end up redeveloping a strong SLP off the coast. it's the best synoptic setup we've had in a while (not saying much), and it's approaching the 7 day barrier, so it's worth monitoring IMO

The stronger the NAO develops behind that threat, the more likely it is to come in colder. Basically, if the Archambault signal comes in more robust, we’ll likely have a better shot at snowing there since that 50/50 would be doing a better job of wave breaking that retrograding block to accelerate it. If the NAO phase change looks weaker, then the storm is warmer.

Regarding that ... you know the 00z actually belayed the -NAO ( as well as it's retro trip across the N. Atlantic Basin) until mid way through the first week of March.  That sort of disconnected the 28th system ...which I guess we'd sort of chosen as the one?  anyway, it was too far removed from it to assess it as a correction/index scaled event ( H.A.).  

Not to say there isn't an HA signal in play out there...but the runs prior through yesterday were actually better fits for the 28th, per se.  

But since...the fact that this thing is rocketing E of the Cape in these recent solutions ..tells us that the NAO exertion isn't quite there yet.  These runs look more like a bigger dose provide by the Pacific, then they do a retrograde hemisphere.

Simply posting a clown Range torch or nao failure map at 384 hours usually illicit nothing if folks are not worried or even if they know it could happen , it’s kinda like ok whatever . It deserves a bun or 5

That’s why I started tracking and getting excited about rainstorms and torches as well, only tracking snowstorms was just getting me frustrated and it wasn’t fun anymore, so I made the decision to start getting excited about warmer weather and rainstorms too. That gave me a lot more enjoyment with this “winter”, despite it not really being much of a winter at all. Instead of getting upset about what we can’t control, why not make the best of the weather we get?

And equating it to someone posting ensemble analysis was pretty horrendous.
