An upper air sounding from the Slidell, Louisiana, NWS site, located about 85 SM west of the accident site, depicted a moist low-level environment with saturated conditions from 500feet AGL to 6000feet with a capping inversion.
At the time, it was expected that the main threat would be straight line winds, but low level hodographs were strong, with storm-relative helicity values of 300-400 J/Kg and upper air soundings with 0-6km shear at 50-60 kts.
