A quasi-linear convective system (QLCS) developed over the lower Mississippi Valley and tracked eastward into the Tennessee Valley during the evening and overnight hours of the 21st into the 22nd.  Ahead of the line, windy conditions developed with south winds gusting to over 40 mph at times.  A few reports of tree damage resulted from these winds.  The thunderstorms and showers produced strong winds at times, producing a few reports of tree damage as well.  Rainfall of 1 to 2 inches were common across the entire area.  As the band of heavier showers and storms slowed down over north central Alabama, rainfall amounts increased to over 3 inches in parts of the Huntsville metro area causing localized flash flooding in a couple of poor drainage locations.  Small creeks and streams experienced rapid rises for a short time period, but no significant river flooding was reported.
