During the morning of December 2nd, thunderstorms ignited along a convergent axis parallel to the upper-level flow. This set up over urbanized New Orleans, and caused flash flooding that morning. As that complex moved eastward, a strong cell moved over Lake Pontchartrain and produced a strong wind gust over the southern part of the lake. That cell was the last of the storms that day.
