Showers and thunderstorms, particularly during the late afternoon and early evening on the 27th brought very heavy rain to the Eastern Shore and caused flash flooding. Soil conditions were wetter than usual for late June leading into this event and made it easier for flooding to occur. Event precipitation totals reached two to three inches, especially from northern Queen Anne's County north to the Pennsylvania border.  Lighter showers arrived around sunrise on the 27th. Precipitation remained fairly light until late in the afternoon. The showers and thunderstorms ended by the middle of the evening on the 27th. The heavy precipitation was caused by an anomalously strong low pressure that moved through the Ohio Valley on the 27th. Its warm front moved northeast through the Eastern Shore during that evening as a secondary low pressure system formed along it. Thunderstorms with the very heavy rain developed in the warm sector south of the front and moved through the Eastern Shore. In addition to the flooding, isolated wind damage also occurred.
The heavy rain on the 27th continued the trend of a very wet month of June across the Eastern Shore and Maryland as a whole. The June Maryland statewide average precipitation of 8.94 inches ranked as the third wettest on record dating back to 1895.
