Severe thunderstorms moved southeast through Charles and St. Mary's counties during the evening of the 7th.  Two tornadoes were produced by these storms across northern St. Mary's County.  The tornadic storms first passed through Charles County.  A funnel cloud was spotted along Route 301 near Bel Alton.  A rotating wall cloud was spotted on Trinity Church Road in the eastern portion of the county between routes 6 and 234.  "Ice cube" sized hail fell near Port Tobacco.  A waterspout was reported on the Potomac River near Swan Point.  Next, the storms moved into St. Mary's County where they produced damaging winds, tornadoes, heavy rain, and hail.  The first tornado touched down near the intersection of Route 236 (Thompsons Corner Road) and Woodburn Hill Road in the community of Thompson Corner (just west of Mechanicsville).  The tornado traveled straight east along Lockes Crossing Road for one half mile before dissipating.  Along its path trees were downed, a roof was damaged, a machine shed lost its roof, and a 30x70 foot barn was destroyed.  The tornado had a path width of 75 yards and was classified at F0 strength.  The second tornado touched down near the intersection of Route 235 (Three Notch Road) and North Sandgates Road (Route 472) near Oakville. It moved northeast along North Sandgates Road for two miles before it pushed offshore. It became a waterspout that tracked toward Broomes Island. Along the tornado's inland path several trees and power lines were downed.  One tree fell onto a trailer home, significantly damaging the structure.  Two other homes sustained minor damage. The twister was 100 yards wide and was rated at F0 strength.    Trees and power lines were downed by high winds in the communities of Hollywood, Leonardown, Charlotte Hall, Oakville, New Market, Laurel Grove, and at Summerseat Sanctuary. Trees had to be cleared from the following roads: Friendship School Road, Bishop Road, McIntosh Road, Clover Hill Road, Queentree Road, Jones Wharf Road, Cat Creek Road, Laurel Grove Road, Morganza Turner Road, and South Sandgates Road. Two cars were crushed by fallen trees in Hollywood. Nickle sized hail was reported in Mechanicsville.  A spotter in Hollywood reported 3.15 inches of rainfall in one hour and 45 MPH winds. Flooding was reported on routes 235 and 246 in Lexington Park.  Other roads that were inundated by water include Baptist Church Road, Mechanicsville Road, Dr. Johnson Road, and Foley Mattingly Road. Two unconfirmed reports of funnel clouds were received from residents of Hermanville and Scotland.  The Scotland observer said the funnel was spotted over the Potomac River.  Lightning with the storms started a house fire in Hollywood and a shed fire in Mechanicsville.  In addition, heavy rainfall from these storms caused basement flooding in parts of Calvert County.  A total of 2.90 inches of rain was recorded at Solomon's Island.
