He's a troll...don't pay him mind.

Anyway...it does look decent, though certainly not close to June 1st, 2011 levels.

Nowhere near that one of the big differences is temperatures. I remember driving through ORH county and it was 90-something before those storms. Incredible to see the cirrus from the supercells that day reaching from springfield to where I was.

SUMMARY...POORLY ORGANIZED MCS OVER CNTRL NY MAY BECOME MORE

ORGANIZED AND CONTINUE TO PROGRESS ESEWD. SMALL BOWING SEGMENTS AND

SUPERCELLS WITHIN THE BROADER CIRCULATION WILL BE CAPABLE OF DMGG

WINDS AND LARGE HAIL LATER THIS AFTERNOON.

DISCUSSION...A WEAK UPPER WAVE OBSERVED ON 15Z WV IMAGERY OVER W

CNTRL NY APPEARS TO HAVE EMANATED FROM SRN MN 24 HRS AGO. THE SUBTLE

WAVE HAS PROVIDED SUFFICIENT FORCING FOR ASCENT FOR THE DEVELOPMENT

OF A CURRENTLY ELEVATED COMPLEX OF STORMS...NOW ORIENTED ACROSS

CNTRL NY. 15Z SURFACE ANALYSIS PLACES A WAVY STATIONARY FRONT FROM

SRN NEW ENGLAND TO APPROXIMATELY BUFFALO...AND SHOULD SERVE AS A

FOCUS FOR CONVECTIVE DEVELOPMENT/SUSTENANCE THIS AFTERNOON. WITH THE

PERSISTENCE OF A BROADER ERN UPPER RIDGE...WELL ABOVE NORMAL HIGH

TEMPERATURES FORECAST IN THE UPPER 80S TO LOWER 90S F AND A

LINGERING MOIST AIR MASS /CHARACTERIZED BY DEW POINTS IN THE MID TO

UPPER 60S F/ WILL ERODE REMAINING CONVECTIVE INHIBITION AND

CONTRIBUTE TO MODERATE INSTABILITY. MODEL FORECASTS SUGGEST NEAR

SURFACE-BASED CONVECTION IS POSSIBLE IN THE 17-18Z PERIOD...WITH A

SUBSEQUENT INCREASE IN DMGG WIND POTENTIAL LATER THIS AFTERNOON AS

LOW-LEVEL LAPSE RATES CONTINUE TO STEEPEN. THE 12Z BUFFALO SOUNDING

REFLECTS AN EWD ADVECTION OF THE EML...WITH STEEP MID-LEVEL LAPSE

RATES NEAR 7 C/KM. WITH STRONGER MID-LEVEL WINDS AROUND THE

PERIPHERY OF THE RIDGE...OCCASIONALLY ROTATING STORMS AND

SEMI-ORGANIZED BOWING SEGMENTS CAPABLE OF LARGE HAIL AND DMGG WINDS

WILL BE POSSIBLE AS SURFACE-BASED STORMS DEVELOP LATER TODAY.

the MCS is decaying as it runs into CIN and building heights. The warmfront is also basically stalled with the greatest shear well to its north and the greatest CAPE displaced well to the south.

Keep in mind the thermodynamic environment at 11 a.m. isn't going to persist all day... that CIN is being eliminated as the boundary layer warms and moisture pools.

500mb heights have been building but they are supposed to fall again later this afternoon and that's when the fun could pop. LEt this MCS die out and leave some outflow boundaries.

Things really are putrid with the wind directions for the eastern half of sne. hate the ocean on days like this

What's actually going to screw you out in eastern Mass is the fact that you'll be on the other side of the warm front. On days when you have really steep mid-level lapse rates in place along with high dews/instability you can get severe down to the coast and the sea-breeze doesn't have as strong of an influence as it normally does.

MCSs almost always decay around this time no matter what the environment....it throws out boundaries for convection later...when you actually want it to fire.

IDK- there is just never a chance in this setup. I mean I think I get your point, but even if we are on the other side of the warm front, the sea breeze will destroy any threat. you know this though, i think you were just stressing the importance of the warm front.

I see what you're saying.

Can't rule out something later on tonight like elevated convection.
