A wave of damaging winds produced widespread and signficant damage to portions of north central and northeast Alabama during the late evening hours of the 12th into the early morning hours of the 13th.  These winds have been attributed to wake low / gravity wave combination on the northwest edges of a decaying mesoscale convective system (MCS) across central Alabama into northern and central Georgia.  Sustained wind speeds of 40 to 50 mph were common over a period of one to two hours, especially across Morgan, Cullman, Marshall and Jackson Counties.  Damages were most severe in the communities of Guntersville and Scottsboro where widespread damage was reported, and power was knocked out as numerous large trees were knoccked down.  Schools were closed in both communities for up to three days.  Many roads became impassible on the morning of the 13th due to the tree damage.  Trees were knocked down onto homes, vehicles and trailers, entrapping one individual in a camper in Scottsboro.  In Scottsboro, power was out for no less than three days in some cases.
