Jan 11-12 Model/Forecasting Discussion

How do you know this isn't a shutout? Models don't exactly get the cutoff right when our area gets shutout of Miller B's or other storms that redevelop too late for us.

Similarly, how do people seem to know that this is going to be a shutout?

It is the upper air depictions that are especially ugly, that lead us to think that even 2-4" isn't happening, even though the models still give us that much, verbatim.

I guess this is the only reason why I can see the cause for the pessimism...

We've been through this agony before, so I prefer to be realistic.

i know a lot of people talk about the seasonal pattern/seasonal trends/etc, but I don't think that just because we've been screwed on the past few events that we are destined to be screwed for every or the majority of events this year. As an example the opposite way-- It found a way to snow pretty much every event last year until after Feb 10th where we couldn't buy snow, including the Feb 26th MECS for areas further north.

It was just a suggestion, and I thought it might dampen the back and forth thats going on right now. No need to be so defensive! Unfortunately some people feel like its their civic duty to be the "adult" and squash any hope others might choose to hold. It gets old real fast!

But what does that have to do with me? I'm usually the most above the board optimistic person here...maybe way too optimistic. I'm usually the one rallying the troops..not sure where this whole meme of me being negative comes from. I'm the one down in the trenches, among the few holding out hope down to the wire. I dunno...maybe its frustration.

Don't worry, I'm going to bed. Ian (i know you're pissed) clean up the thread...I'm out of line, but stupid ass Ji kinda set me off. He better not ever come to me when he's 5 posted again begging to come back.

The problem as I see it is TOO MUCH BLOCKING this season.

Usually what we see when we get decent snows is this:

1) It gets cold.

2) Blocking relaxes and we get a decent storm

3) Cold for a few days then warming, usually followed by a rainstorm.

4) Blocking redevelops, back in the icebox.

5) Blocking relaxes, we get more decent snow

6) Cold for a few days then mild up, perhaps a cutter/rain storm

Rinse and repeat.

Trouble with this odd winter out - we are suffering from a case of TOO MUCH BLOCKING.

For us in the SOUTH Mid Atl - We are going to absolutely freeze our asses off like you would not believe.

This blocking is unbelievable and it will not stop. This is -NAO blocking on steroids and it is winning the war on La Nina. It's harder to break down than Rocky Balboa.

It's going to be so cold this month we'll be comparing it to Jan '82 and Jan '85. Cold temperature records are going to tumble this month. But the NW flow is going to shear the hell out of the shortwaves.

An Alberta Clipper will bury Jacksonville Florida in 5 inches of snow sometime this month. That's how far south the clippers are going to be because of the extreme blocking and cold.

DCA will be like New England in terms of cold, sans the snowpack.

Well for whatever it's worth the flow in the GFS lifts and relaxes quite a bit after about the 20th or so. We get some kind of cold blast after next weekend then things are pretty blah. In fact, it doesn't look like much of any kind of blocking/-NAO in the longer range. There certainly looks to be some cold air up in Canada, but mostly staying there. It's been showing this now somewhat consistently for a little while. Not sure if it's temporary or what.

Really?

Sounds like the opposite, no? Don't we WANT that Ohio Valley low to be further south and transfer to the coastal low faster? It sounds like the Euro is a lot less likely to screw us, Miller-B style than the NAM/GFS for example...I guess we'll find out in a sec, hehe.
