I don't know..one lonesome cell here. All the action up north as usual. We are a pit.

 

It at least had the idea correct of something working through western MA and right about this time too actually.  It did have more activity going on.  I guess it all depends on how tough you want to be on grading these types of models.

They shouldn't be taken verbatim, but looking atthe 00z run...it seemed way overdone. Anyways, it didn't change my thoughts knowing the environment. We are just south of getting better convection.

I feel like as with any model during the summertime, convection is difficult to pin down. Like you are saying, having a knowledge of the environment is definitely important before reading too much into them. SPC WRF has been out there though, at least for SNE.

Saturday is the real deal

for busts

 

 

...OH INTO PA...NY...AND NEW ENGLAND...

SCATTERED SHOWERS AND STORMS ARE EXPECTED TO BE ONGOING NEAR A WEAK

COLD FRONT FROM NRN OH NEWD ACROSS THE LOWER GREAT LAKES AND INTO

NEW ENGLAND. CLOUDS AND PRECIPITATION WILL LIKELY HAMPER

DESTABILIZATION IN AREAS. STILL...MARGINAL HAIL AND A FEW STRONG

WIND GUSTS WILL BE POSSIBLE GIVEN FAVORABLE DEEP LAYER SHEAR AND

MAINLY UNIDIRECTIONAL WIND PROFILES. THIS THREAT WILL LIKELY PERSIST

DURING THE DAY WITH EPISODES OF STRONG TO SEVERE THUNDERSTORMS. IT

APPEARS THE GREATEST DESTABILIZATION WILL OCCUR FARTHER SW INTO WRN

PA AND OH. HERE...STRONG HEATING AND CONVERGENCE SHOULD BE

SUFFICIENT FOR A FEW SEVERE STORMS DESPITE MORE MARGINAL SHEAR

PROFILES.

lol, yeah I'm a little surprised.  But this threat has been waning in the models the past few days, at least a little, so the ramp-down makes sense.

I guess the SPC is riding the NAM with clouds limiting destabilization across the region.  The GFS still looks pretty solid and the timing is nearly perfect.  The GFS also has as much as 2500-3000 SBcape with MLcapes in the 1500-2500 range and LI values as low as -6C to -8C with 0-6km shear shear values in the 30-35 knot range.

Maybe it's just perception but it just seems like many of our long big heat waves we don't typically have a major outbreak of severe wx and more in the way of isolated or scattered stuff. Doesn't this one look that way to you?

 

You have the weirdest rules of thumb. 

 

There's still a lot of questions for tomorrow.
