A frontal boundary was stalled along the northern Gulf on February 18th. As cold front moving south through Texas and northern Louisiana, a surface low began developing where the 2 boundaries met in the northwestern Gulf. The low steadily deepened while tracking east along the Louisiana coastline which enhanced height falls over southeast LA. The increased buoyancy from the height falls perfectly lined up with convection over New Orleans which lead to heavy rainfall and flash flooding.
