As a slow moving upper level low pressure system moved across West Virginia on the 5th, cold air filtered in aloft. Thunderstorms formed in the instability of the afternoon. Despite storms not being very tall, freezing levels were under 10,000 feet and the storms were able to tap into this to produce hail. Isolated flash flooding also occurred due to repetitive, slow moving storms.
