I think that NYC thread was mentioning MESO's are the way to go on this one

 

I would take any slowing trends on globals ...as a red flag

 

I think this is more of an after 3pm special for E/NE mass

 

waiting for 12z  BTV WRF 4 km to come out

 

6z gave .5 plus from far eastern mass (N-S) up thru down east maine....including BOS

6z BTV WRF had NICE coastal front setting up SW-NE from about Wellsley to Reading/Lynnfield  to Newburyport,  but just like last storm it's still all snow east of CF ...just upper 20's low 30's on eside  upper teens/low 20's west side.  ALSO it's only a brief like 4 hour Coastal front before it collapses to the coast.

If I recall correctly the Rgem does very well with these types of systems and the GFS does not due the spatial physics of the model

 

 

The Euro stinks from my past experience on these sort of systems in regards to QPF, it tends to do okay on tracks but is usually dry...I'm not 100% but I think pure northern stream disturbances the GFS is usually a better model, if you have interaction between the NRN and SRN streams the Euro is better

Ummm....

12z BTV WRF came in with a  bit less QPF ....actually not that much different for bos metro...(compare to 6z 4km) ....   .4 to .5  instead of .5 to .6

 

FWIW looking at the differences in the 6z btw wrf model's the 12km had more qpf than the 4km

 

also gets areas along S shore E Pym county /cape islands  35-37  around 3-7pm tomorrow with CF draping from say Peabody to Medford  at 4pm then shifting a tad east and tightening a bit to say Quincy NE to Manchester by the sea

 

track of MSLP seems interesting from Off toms river nj 10am (1010mb) ) to just south of MVY 1pm (1009mb) to 4pm (ACK/slowing  by second shortwave) 1009mb then ....at 7pm it's center is due North and deeper (1007) mb  on top of  upper cape/ (east of Marshfield) then 10pm about 60 miles east of BVY and 1004 mb 

 

so I don't think this is sorted out yet but

4km nam has hit eastern PYM hard for a few runs.  Some type of onshore flow there for sure. 

 

Synoptically I think the Euro tells us the story this run.

There should be no reason to think the Euro will be wrong at this timeframe.  24h out from system starting.  Both s/w are over land now and have been sampled pretty good.

we shall see

 

snow goose says euro pretty much blows with these...I hope euro looks good at 5 H and  surface track (I think) I will leave QPF to meso's  on this compact little thing

Euro still looks like 2-4 maybe a spot 3-5 in ern areas. Real close to being a bit more of that energy trends stronger.

 

I think given the analogs and the fact that euro is close to more warrants a closer eye on meso's in next 12 hours

 

high end advisory snows with an eye toward 5-8 over NE areas if meso's sniff out stronger trends
