The bullseye is often just NW of the dryslot because that area stays in the heavy snow the longest.....as the band pivots back to the east. Each storm is different but that is a common occurrence. You can of course get secondary maxes from banding further NW and such.

Yeah models sometimes are a little too generous in DS regions and not beefy enough in the area that has high mid level RH, just nw of it. I think that sometimes the heavier snows are also ratio related...not that models necessarily busted too low with qpf. The NAM seems to focus on some strong low level convergence too.

I'm not afraid to say it..some places will pull 30 out of this. Yup

14 of snow and 16 out of your hiney?

who see's 30 and why/how?

i was asking if this has potential to stall .....i.e how the 250 HPA anomalies look but not really much feedback yet. if it slows /stalls than it is possible i guess.

The qpf is 6 hour increments, the 700mb rh is time ending that hour. So you can have a dry slot over Wilmington and 1" of qpf for 0z Thu NAM, for ex, if the precip fell in less than 6 hours, between 18z and 22z

True, but I should not have more total QPF than areas to my nw that never dry slot...that is my point.

Nope don't need it to stall. X-mas storm 2003 dropped over 30 near ALB and was progressive..there's other too

Yeah I agree on this one, we don't need it to stall to see some impressive snow totals, there is going to be a great deal of moisture with great lift, and were going to see some sick snowfall rates.

This is what I was saying, yesterday.....storms like this drip 30" in 12 hrs sometimes.....Earth light got just over 30" in about 12 hrs in that blizzard.

NEVER expect that, but it's not impossible and is VERY localized.

Exactly..this is precisely how you get those mega amts. You don't want it to stall out.

You'd never expect that much ..but every single one of us here..including the mets knows there will be some 25-30 inch amts in a few lucky zones. Noone knows where..but we all know those big numbers will occur
