The episode as NWS OKX wrote it up.
A weak cold front worked through southern New England towards the area. Ahead of the boundary a moist and moderately unstable airmass was set up. Given cold temperatures aloft and steep low level lapse rates, one storm was able to become severe and produce a cluster of damaging wind gusts in southern CT.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS New York, NY wrote its last area forecast discussion before the first event at Jul 30, 3:23 PM EST, 1 hour 7 minutes earlier.
