...ERN NY INTO SRN NEW ENGLAND...

A LEADING UPPER DISTURBANCE IS FORECAST TO AFFECT ERN NY INTO SRN

NEW ENGLAND DURING THE LATE MORNING/EARLY AFTERNOON HOURS WITH

MOISTURE MOVING NWD OFF THE ATLANTIC. HEATING UPSTREAM ACROSS

NY...AS WELL AS LIFT ASSOCIATED WITH LOW-LEVEL WARM ADVECTION SHOULD

RESULT IN AT LEAST ISOLATED STORMS. SHEAR PROFILES WOULD FAVOR

SUPERCELLS CAPABLE OF LARGE HAIL AND GUSTY WINDS. LOW-LEVEL SHEAR

MAY BE WEAK THUS ANY TORNADO THREAT SHOULD BE BRIEF AND LIKELY WEAK.

OTHER STORMS WITH A DAMAGING WIND THREAT MAY APPROACH THE SRN NY

AREA LATE SUNDAY NIGHT AS ACTIVITY DEVELOPS ACROSS PA.

Sound's like there's a decent shot of it occurring. The usual caveat of "what could go wrong" does apply though.

Shall we count the ways... I'm seeing morning convection as the big issue, with not enough capping being the culprit there. The apparent lack of shear looks problematic as well. Best dynamics will be well to the south, closer to the triple point. Looks to be a high cape low shear event, much like the early June surprise events. A supercell or two with hail seems to be the case, if it all comes together just right.

Assuming there's a trigger later in the afternoon, the HRRR is rather encouraging for western SNE today. It wouldn't be a bad thing if the morning convection is on the weaker side, allowing for more destabilization and some residual outflow boundaries.
