And we're off - first threat for a few mangled flakes

Although things look to be playing out similar to winter when models slowly catch on to amplification, I still think the upper air pattern and ampliciation is just a bit flat. When looking at the mid level height field on the models, it's just not quite there in terms of what you want to see if you're hoping to tuck a strong low pressure in near the coast.

Also, when comparing the 12z GFS to the 00z GFS during the period of the best height falls and trough amplification, the 00z run was actually much more robust. The ensembles being closer to the coast offer some hope.

agreed. Just taking a step back, its just not there right now.

Yeah, that's what I'm trying to get at.

Sometimes it is hard to pump the brakes for a second on the whole roller coaster of events that occur prior to a potential storm. With the ever expanding plethora of information we can now get our hands on, it's really important to put everything in perspective.

For one, it's not winter. It's not even close. The pattern is very (and I repeat, very) favorable for the calendar date. But that doesn't mean it's not fragile. This is not the ticking time bomb type pattern(s) we saw last winter. Those patterns, it was like each shortwave was a flame lit in a room soaked with gasoline. It was bound to happen. Here, we need a bunch of things to go right to get the storm up the coast -- and then a bunch of things to go right to get frozen precip -- and then a bunch of things to go right to get it to the surface and sticking.

Second, if this storm doesn't work out, who cares? The investment in this storm should be as low as it can possibly be. It's October 26th, really, this is equivalent to a spring training game. Don't get me wrong, I'd be stoked if we saw flakes, but if not you shrug your shoulders and move on.

Finally, I hope people use this perspective on a more broad scale through the winter. I already saw people saying "this block sucks, it's not impressive". Guess what? it's fine. Positive height anomalies over the Davis straight is a good thing during the cold season. We aren't going to get blocks like last year very often--maybe not for a while. Hell, we aren't going to get storms like last year very often. People wouldve killed for a decent davis straight positive anomaly in 2006-2009. So I hope during the winter we remember this.

In a fragile pattern on Oct 26, hopefully people don't get too pissed if it doesn't work out. We have 5 long months ahead of us -- with much more dramatics and more favorable setups than this.

quite a few people here and on other forums have mentioned that its not possible to have snow in the mid atlantic this time of year

well this is what happened Nov 11, 1987 - only 13 days later then the event coming up and further south - so anything is possible - and in this year of extremes even more so
