The region remained in a warm and humid air mass as an upper level ridge remained just south and east across the western Atlantic Ocean. At the same time, a weak upper level disturbance passed by to the north across southern Canada.  This upper level disturbance allowed showers and thunderstorms to develop across the region during the afternoon and early evening hours of Monday, June 24th.  With a moist and unstable atmosphere in place, some of these storms became severe, with large hail and damaging wind gusts.  Thunderstorms dissipated by later in the evening, as the disturbance moved east of the region and the atmosphere stabilized.
