As WAR expands, do our snow chances increase? First wave may produce a middling event-solid advisory and possible low end warning for MLK Weekend

Not a good performance from the euro. Call a spade a spade. Skynet was better though

It did well last week in the SE US event but it also was having to tick NW late for the final 24-36, it was just that the NAM was so bad most did not realize it.  It may be having the same progressive bias down there again with this next one as its been ticking N now the last 2-3 runs

So it is ...  heh   true wow moment for us nerds ( LOL )

Wholesale capitulation really just happened.   ... Unprecedented in the storied history of the GFS vs Euro, whence the Euro concedes so vastly in favor of the GFS. 

If you place the 36 hour illustration of these two, 12z solutions, side by side, while considering their history in coverage of this event, their differences are so minor that you'd objectively have to consider this as > 90% correction of the Euro toward the GFS.

For all intents and purpose, total - I mean, they're never going to be 100% anyway.  This is like 90th percentile likeness at this point.    GFS left; Euro right

Not sure if this some how Euro diminishing quality returns, vs perhaps improvement in the GFS (grudgingly having to admit -).   They've both been thru with upgrade mill in recent decade. It's an interesting question.  I think also ... attribution is causing model performance overall to be impeded; compression is intrinsically more difficult on guidance technology, and we just seem to have more of that as a seasonal predicament.  

Either way, I've never seen the Euro gather up all its belongings, sell the farm and bodily move into the GFS' neighborhood ( and I mean like right next door! ) just 30 or 36 hours ahead of anything.

BOS gets hammered on that run. 

Verbatim they could be in the jackpot zone. I'm curious though if the Euro is a bit too far southeast with the heaviest banding. Not just saying that because of the known bias that the heaviest banding tends to be northwest of what models show but because the evolution of the storm makes sense for the banding to develop well northwest and then maybe collapse towards center, but not sure that happens in this case without lack of H7 development. 

I still also wonder if we see two bands develop. One well northwest that smokes Berkshires and northwest Connecticut and a second which would be from about BOS through ORH to Kevin and in between gets kind of screwed. I am a little nervous about this scenario.

GFS may be the new king, at least for the short term.  I wonder what changed for the Euro to cave so much on this run?

In any case, I look forward to a good 4-8" here in E MA. 

Didn’t the Euro just smack around the GFS last week?
