POSSIBLE MAJOR EAST COAST LOW OCT 31- NOV 2 -- it is back


Recommended Posts

well it is now obvious  that the  threat for an  BIG   Middle Atlantic / east coast Low  OCT 31- NOV 1is not going to happen .   There appears to be growing support for a significant Low over eastern Great Lakes....and much of NY state & New England for snow to rain OCT 31- NOV 1 

 

The  pressure  gradient  between the   cold HIGH over MN/ WI and the Low over Newfoundland gets pretty strong and  strong N winds   should  drops temps  below 32   morning of  NOV 1-2  from NC to Maine and over  KY WVA OH  as well.   Many areas could get Mid 20s in Middle Atlantic  and even colder over  New England

Ops will probably stay on the roller coaster for another 3 days. How deep the trough digs, how the pieces of energy interact, does h5 closes off and if so where/when, and does the trough go netural then negative are really difficult questions. 

 

Euro ens mean last night shows the closed h5 contour over western md/pa. A cluster of lp's from the euro members showed up in MD/VA. Majority were east of course but the low location plot definitely took a turn towards upping the chances for a closer to the coast solution and more impact further south.

 

Euro op from last night speaks for itself.

 

12z GFS dug all the way to nc/sc and closed off but the tough never went negative so out she goes. Phasing on the gfs was messy and untimely. 

 

12z GGEM was right in between the GFS and Euro ops. But still messy on the phase. 

 

The short story is there is still a pretty wide range of possible outcomes. Anything from a non event (other than wind) to pretty decent storm up the coast could easily happen.

This is a weird solution. It's odd for a northern stream closed 500mb low moving off the Virginia coast isn't able to bomb faster than the GFS is suggesting.     I guess it's just a progressive trough that digs a little too late.   12z  Euro is a little reasonable but still takes a lot of precip off shore.   I'd expect H5 would be more of a positively tilted open trough if this scenario were to verify.

 

New York and New England look like the best probability for a big hit,  judging by the ensembles and last nights Euro.
