Off how?

too flat? i mean i dont know.. i still have trouble buying these tracks on the euro but the euro has better skill than the gfs so the last few runs are hard to ignore totally. middle ground is usually a good bet though they're all spitting out kinda similar qpf at this pt given the track differences.

Nothing better than a run with a better track and less precip.

You are really into good conclusions this season.\

If you run the 500 mb animation (WRF, hee hee, or model of choice),

the final few frames show that the 500mb vorticity dampens.

Simply put, the storm weakens as it crosses the Blue Ridge and south central

Apps. and nothing else is available to spin up the storm until it reaches the

baroclinic zone offshore. (this zone being the persist clash of standing temperature

patterns associated with the Gulf Stream).

What was entirely different last winter was that the 500 mb pattern was the alter image;

as storms transitioned into our area, the shortwaves reinforced the vorticity.

Hopefully, the redtaggers here agree with my concept and can clean it up and explain

it better.

Sadly, until the spacing and timing of these short waves change a lot, we are stuck in

a repeating cold/dry pattern. The repetition seems locked in.

uh oh, you've been reading too much of Tipp in the NE forum

:P just kidding and sounds like a good explanation

So its basically MORE than 0z.

i dont think that's fully accurate even if some stations have more. it's pretty much the same but the qpf shield is slightly east here on the whole, slightly west down south in va though. run to run it's basically the same output.looking at hundredths of qpf is useless imo.
