Some of these older events are quite the challenge! I have poured over this one a few times.
The strongest tornado to occur on January 20, 2010 was an EF-3 that moved through Harrison County, TX into Caddo Parish, LA.
This tornado developed in open country near the Jackson-Caldwell parish line. It moved to the northeast near Corey. The survey states the tornado path was not continuous. A tenant farm was destroyed.
20+ homes destroyed in the Alexandria/Pineville area with 50 more damaged. Several garages and roofs were blown away and four homes were shifted.
It developed near Lydia causing minor damage to a few barns and trees. It moved northward at approximately 50 mph and strengthened. Max winds were estimated at 110 mph.
