This is pretty sweet. Strong vort plowing through Mass. H7 and H85 slightly closed off. A little Atlantic inflow with deep mid-level moisture and omega. Strong sfc convergence thanks to that mini sfc nuke. There isn't much to not like with that run up here unless you hate snow.

It does look very iffy for NH. I'm not sure the warm front makes it that far north.

Not the right thread so I'll make it short, but the euro had 30s here 18Z Friday. An 18-00Z fropa would be best case scenario since the mixing/clearing at night would be more of a friend than foe.

Dude even you were poo pooing it two days ago, no insult but every model did not have the dynamics that are really starting to show, sorry man. FWIW BDR on the Nam instability plus, TTs 44

Total Totals Index: 44.25 C Risk: Scattered moderate thunderstorms

 

We had a big storm coming..I don't think it's worth sounding the alarms over....it was just a mention. Drag does like to get excited over 1-3" deals.

DGZ is up around H7, so yeah the low level lift isn't going to be ideal for areas south of the Pike it looks like. It's almost like a mini dry slot, if you want to think of it that way, that works through southern areas.

 

 

Yeah you can see that we may struggle with snow growth for quite some time south of the Pike... but could put down a pretty impressive 1-2 hour window of snow when omega is deeper through the column. 

 

The GFS actually has the DGZ totally dried out for a window (NAM doesn't) so that could mess with thing.

 

One thing I like for my viewing area is that boundary layer issues for the coast seem to have been wiped away on overnight runs. Some of those runs yesterday were a torch. Even GON may put down a couple inches. Probably a paste bomb for the valley/shore with us being isothermal around -1C for a good 100mb.
