The event on August 7th 2023 featured a period during the morning hours, when a decaying MCS passed through the area during the early morning hours and likely changed the environment to the point where it impacted the convective event later in the day. A warm front positioned over the north during the day kept the forecast area in the warm sector for the event with a stout cold to the west over the Midwest states. Aloft, a distinct 500MB trough over the OH Valley with a strong 50 to 60 knot jet streak rounding the base of the trough through KY and into WV. The axis of the trough was swinging through western OH at the time with ingredients coming together shortly after 10-11am. With the MCS earlier in the morning priming the environment for a midday convective initiation. Numerous cells began to develop across northern WV and slowly creeped into our forecast area. Towards the end of the event, a well developed supercell formed in Preston County WV. The cell produced ping pong sized hail and in isolated reports, there was golf ball and hen egg sized hail.
