Nice!!!!

Bahama blues here. Great looking satellite out ahead of this stuff. Have to wonder though if that mid-level dry air moving in will really hurt, despite the building lower CAPE

Have to watch for rapid destabilization out ahead of the line given the sky conditions and rapid jump in temps...may have a similar affect to parcel acceleration that you would see with steeper lapse rates because the air is becoming less buoyant rapidly.

You gotta be careful with TVS in setups like this with very strong shear. I don't think Radarscope does this but these are probably elevated TVS signatures...so there are probably 2 or 3 bins (forget the minimum requirement...think its 3) on successive scans meeting shear threshold and above a certain distance above the ground.

Nothing is really standing out in terms of rotation. OF course much of this stuff is in some awful radar coverage but going up a tilt or so, nothing is really impressive so a sign anything llvl is probably minor as well. Don't think there is enough instability right now to really get something spinning. May actually have to watch into Berkshire County...some higher sfc vorticity there per mesoanalysis with increasing 3km Cape.

cells firing east or the Berk as the airmass begins to destabilize and MLCIN has eroded.

Kind of shocked we haven't seen a downstream MCD or watch extension yet

You get enough MLCAPE or 3km CAPE in this and you could be looking at the potential for a stronger tornado

The valley probably does but that is going to be the product of mid-level air advecting in which is also going to negatively impact potential for thunderstorm development down this way as well. However, its been noteworthy that the CAMs have become more aggressive and have remained consistent with developing convection, even down into CT later this afternoon. We'll see...too much mid-level dry air can really screw things...not too mention its rather warm aloft too

That line is looking pretty good with some very noteworthy rotation. Erode the MLCIN out ahead of it and boost up those values and this may be an interesting afternoon in NNE. Looks good for some clearing out ahead of the line too

We'll see what can happen south of Rt. 2 and especially getting towards the Pike and farther south...mid-level dry air going to be a big concern and tough to overcome. With this said, that would keep anything that develops more isolated so if something pops and can get a robust enough updraft, it will have an environment all to its self. Will be tough this...instability won't be sufficient I don't think

yes

There is a pocket of steeper mid-level lapse rates in NY advecting northeast. This may weaken but something to watch to lead to some instability enhancement for eastern NY into VT/NH

Quite the storm down in Louisiana.
