SPC WRF has NW Mass up through S NH getting nailed over the next few hours. Down here it will probably take until 22z or so to start getting the better forcing in. 

 

Do you think that's right?  I don't see that to be likely (though there is the burst of activity down toward Westhampton/Huntington and the other one in SW NH (chesterfield????).

 

BOX had also backed off on their concern for the NW areas.

 

It's become mostly cloudy at this point here.

 

77.2/71 off a high temp of 78.6 at 10:30a.m.

Seems the convection allowing models want to keep things NW again.

 

This is the normalized probability of 40 dBZ echoes.

 

Not too surprised by that with the stationary front hung up back that way. I think at least during the day most of the legit action stays west of SNE though W Mass/NW CT probably get in on it a bit. 

 

By evening once the LLJ begins to increase a bit and we get some assist from the UL disturbance in the Carolinas things should start sliding east a bit.

I think you'll get a couple rounds of storms today.

I think that stationary/regenerating convection S of New England is that QPF that the Euro has consistently tried to hammer everyone with tomorrow. Wherever that front hangs up.

As height slowly rise from the east along with this ridge strengthening/retrograding, gradually reducing chances for convection should take place.  The trough retrogrades west and fills, taking the convergence zones and vestigial mid level laps rates along with it.   

 

Not surprising to see models start pushing the better action NW... 

 

The 12z Euro looks like it would carry an impressive MCS threat for next Saturday.

Could be a good sign for us later on perhaps...especially if we can keep cape values up around 2000 J when the LLJ arrives and better forcing for us.  There have been some nice looking storms in eastern NY even with some rotation within them.

 

Another isolated severe threat tomorrow. Marginal CAPE but plenty of shear.
