A deep full-latitude upper trough was sweeping from the central into the eastern U.S.  The trough brought a quick transition to the eastern U.S. from mild fall temperatures to an extended period of well below normal temperatures.  As the trough swept through the southeastern U.S. on November 30th, it took on a significant negative tilt.  Although only marginal instability was noted because of extensive pre-frontal cloud cover and light to moderate rain showers, a strong 50-60kt low-level jet accompanied the trough as it rotated through Georgia during the afternoon of November 30th.  This was sufficient combined with minimal instability (CAPE) in place at the time to support the development of a fairly well marked, yet very narrow, quasi-linear convective system (QLCS) which spawned two tornadoes, one an EF2 causing extensive damage to homes in Gwinnett county, and another weaker tornado in Henry county.  In addition, the squall line or QLCS also produced numerous damaging wind events across north and central Georgia.
