On Friday afternoon of April 11, 2008, a lone thunderstorm
developed along an advancing cold front just north of Lake
Charles near Gillis, LA. As the thunderstorm moved east
following the frontal boundary and basically US-190, the
thunderstorm split into 2 separate storms upon entering extreme
southern Jeff Davis parish across Southwest Louisiana. The
northern storm eventually dissipated, while the southern storm
began to move due east, exhibiting characteristics of a
right-moving supercell. The strong thunderstorm continued to
grow and a
severe thunderstorm warning was issued at 3:19 PM CDT.
The severe thunderstorm continued on a track just north of US
190 moving almost due east now, and continued to get better
organized, with rotation beginning to form within the 0.5 degree
elevation velocity (Storm Relative Motion) product. Thus, the
severe thunderstorm warning was upgraded to a
tornado warning at 3:45 PM CDT.
The severe thunderstorm resulted in a couple of EF0 tornadoes
across southern Evangeline, western and central St. Landry
parishes, along with straight line wind damage.
