      In a new statment issued Wednesday by the National Weather Service, they report that a powerful complex of thunderstorms, known as a bow echo, moved across Missouri and Illinois during the early morning hours of June 27, 2011.

      Extensive straight-line wind damage occurred across northeast Missouri and west-central Illinois with widespread 50 to 60 mph winds and embedded microbursts that produced concentrated area of damage with wind gusts greater than 80 mph.

      The preliminary results of their storm survey of the June 27th storms found two tornado tracks in Shelbina ... in southern Shelby County.

      The first tornadic damage track formed near Elm Street and Douglas Avenue north of U.S. Highway 36 at approximately 12:55 a.m. CDT on June 27th.

      The roof and walls of a corrugated steel building buckled on the west and south sides along with a portion of the roof.

      The tornado moved across U.S. Highway 36 and destroyed three unoccupied house trailers. Debris was tossed about 100 yards from the trailers.

      The tornado continued to move east southeast and caused roof damage to the town power and water plants on Chestnut Street west of Shelby Street. A portion of the gables holding the roof of the power plant were uplifted and tossed approximately 50 yards to he east. Much of the water plant's roof was removed and tossed 40 to 50 yards to the east.

      The tornado then caused minor roof damage on homes and snapped numerous large trees about 10 to 20 feet from the base. Some of the large branches fell on top of vehicles.

      The tornado then caused extensive damage to the roof of the two story town museum on Center Street (Highway 15). Several bricks fell to the ground from the top of the museum roof. Additional tree damage was found east and southeast of the town museum building.

      The total tornado damage track was 1.5 miles. Damage width 50 to 70 yards wide. Damage was rated EF1 (peak wind speeds were 105 mph).

      The second tornadic damage track was just to the south of the first tornado.

      It began west of south center street in which significant tree damage occurred. Some of the trees fell on top of homes.

      The tornado traveled east southeast and hit an assisted living home on Shelbina Avenue. Roof damage was found at this location. Other large trees were damaged in the vicinity of the assisted living home.

      The tornado continued to the east southeast and destroyed a large machine shed built in 2008. The east ... south and west sides and the roof of the machine shed were tossed into several corn fields. It then crossed county road 441.

      The tornado hit a tree line and damaged trees 60 yards wide. Several trees were snapped 15 to 20 feet from the base. Tree trunk diameters ranged from 1 to 2.5 feet.

      The total tornadic damage path of the second tornado was 1.7 miles long. Damage width varied from 40 to 70 yards. Damage was rated EF1 (peak wind speeds were 100 mph).

      The survey team will continue to survey portions of northeast Missouri and west central illinois Tuesday from the storms that occurred during the early morning hours of june 27th.
