On July 24th a closed 500 mb low was digging over NY/PA and waves of surface low pressure were riding north along the associated surface front to the west of the forecast area. A strong 50kt low level jet was also riding northward ahead of the front. This resulted in extremely high helicity values across southern and western Maine. A surface dew point boundary was in place across south central New Hampshire through northwest Maine with readings in the lower 70s to the east of this boundary and in the mid 60s to the west. Sunshine began breaking out to the east of this boundary by mid morning and convection began developing by early afternoon. Storms grew rapidly and quickly began rotating. Storm damage was exclusively related to damaging winds with these storms.
