A strong upper level low over the southern Rockies aided in the development of surface low pressure over north Texas on the 26th. As this low moved east along a stationary front over Louisiana and Mississippi, a strong line of thunderstorms developed during the early morning hours of the 27th. This line of storms moved rapidly across southeast Louisiana during the daylight hours of the 27th. Numerous reports of thunderstorm wind damage were received, primarily downed trees and power lines. Several meso-cyclones embedded in the southern potion of the squall line spawned weak tornadoes.
