The combination of an unstable airmass in place over the region, the approach of a strong mid/upper level trough, the presence of a pre-frontal trough, and the passage of cold front set the stage for the development of severe thunderstorms across east central New York.

The episode as NWS ALY wrote it up.
This was the first severe weather event of 2012. The combination of an unstable airmass in place over the region, the approach of a strong mid/upper level trough, the presence of a pre-frontal trough, and the passage of cold front set the stage for the development of severe thunderstorms across east central New York.
The pre-frontal trough became diffuse during the afternoon and consolidated with the cold front as it moved through. The convection formed into a broken line from mainly the Capital District north and east. Most of the severe reports were hail. The convection tended to diminish in severity by around 7 pm EDT, as by the time the cold front approached the southeast portion of the local area and the instability decreased. Some additional convection did flare up over southern Berkshires in Massachusetts, eastern Columbia County east central New York, and northern Litchfield County Connecticut as the cold front moved through around 9 to 10 pm EDT, although these storms were not severe.
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.
