A typical mid fall stronger cold front was moving through the region during the early morning hours of November 19th. As the boundary moved into southeast Louisiana, a surface low began to develop and depend right along the front. This resulted in more significant pressure falls which enhanced already deep showers and thunderstorms. As those storms moved over New Orleans Metro and the northshore of Lake Pontchartrain, very heavy rainfall produced flash flooding.
