Why would you think a bit further south? The block seems to be a bit further east when compared to the 12z run

looking at 500 vort 90-102 hours...they are fujiwara-ing :wacko2: and the 18z is closer to the upper level low on this run than 12z...hence the swing west should be further south...a step towards the euro in being closer to phasing early

With the blocking it simply can't miss. It's just a question of how it gets there. It really can't hit north of Long Island probably.

Well you have to consider that we are still 100+ hrs for one, so cant rule out anything...further more, were still not sure exactly how the entity that is sandy, whatever she is by this point, will interact with the attempted phasing of the polar trough...you would think they wouldnt be as willing to phase initially as the euro depicts it, but here we have the 18z gfs now coming on board.

I think the Catskills watershed reservoirs are lower probably than before Irene so that's a plus should heavy rain come to fruition.

The flows are actually about 20% higher now Logan and levels are up about 10-15% higher than normal for this time of year. It does look like though that they may be drawing down the water level at the Schoharie Dam.

Also checked out 3 hrly FFG for the area as of today most counties are in the 1-2 inch/3 hour period for flash flooding. Their rather low values are probably tied into the very heavy 2-4 inch area wide rainfall that we got last Friday.

Also keep in mind this time of year the trees and vegetation "absorb" less/very little vs what they can do in August thus more of the rain this time of year goes into runoff vs. absorption.

NERFC has advised of possible river flooding across SE NY up thru the Catskils (for early next week)

While still anything IS possible still now I think confidence has to be high in the OTS track 100% no longer viable and a potential LF most likely from Western LI to the Delmarva as being high.. NJ coast looks to be the prime zone now

Total QPF on the 18z GFS.... this would be a great solution for New England with no real flooding thread from rainfall. Coastal flooding is still huge, but if all of New England is a general 0.75-2.0" of rain, that's not even worth issuing flood watches.

Meanwhile, mid-Atlantic better get the Ark ready...and West Virginia's NW upslope areas better get the snow shovels ready, or excavators.
