MD 1530 CONCERNING SEVERE POTENTIAL…WATCH POSSIBLE FOR PARTS OF THE NORTHEAST AND SOUTHERN NEW ENGLAND

Mesoscale Discussion 1530

1128 AM CDT Tue Jul 01 2025

Areas affected...parts of the Northeast and southern New England

Concerning...Severe potential...Watch possible 

Valid 011628Z - 011830Z

Probability of Watch Issuance...40 percent

SUMMARY...An isolated damaging wind threat from strong gusts is
anticipated this afternoon across parts of the Northeast into
southern New England. Severe Thunderstorm Watch issuance is possible
if a more concentrated corridor of damaging winds becomes apparent.

DISCUSSION...To the north of the favored region for scattered
damaging winds across southern PA/NJ this afternoon, a more isolated
and lower intensity threat is anticipated. With somewhat cooler
surface temperatures, outside of the Lower Hudson Valley, amid
similarly weak mid-level lapse rates, MLCAPE is expected to be more
muted. But moderate to strong mid/upper-level speed shear will favor
potential for semi-discrete convection and transient mid-level
rotation, capable of small hail and generally isolated damaging
winds. Bulk of morning guidance suggests a combination of lesser
storm coverage and instability should modulate the overall wind
threat. It is possible though that an uptick in convective intensity
might occur if a cluster can approach the Lower Hudson Valley to
southwest New England vicinity later this afternoon.
