Listening to the radio and sounds like people are trapped in their car and poles are down. Also watching a live stream and looks like things are in the road blocking the highway.
 
Not trapped in his car, he took shelter in an area where power lines came down. He had to drive over the curb to get out.

In reviewing the 18z rawinsondes from the MS/LA area, the hodos were looking quite favorable by early this afternoon. ML CAPE was still less than 750 J/KG, but shear and SRH profiles were quite impressive.

With the temperature set to drop into the teens in areas that were hit, I would expect considerable damage from frozen water lines in areas without power. The strength of the storms aside the damage toll will mount.
 
Also, 22 homes near Petersburg, IL, in Menard County, were "rendered uninhabitable" by a storm that hit around 12:40 p.m. ILX and SPC have this listed as a tornado report. At least one minor injury was also reported.
