The big question for me was whether I could get far enough south to see a tornado before sunset, which was 4:48pm. The two tornadoes in Louisiana were clearly out of range. SPC shows five reports in Rankin and Scott Counties between 3:57 and darkness. This is basically driving to Jackson, which takes 3 1/2hrs, in round numbers. I would arrive in that area at 4:30. So it would have required a perfect intercept, no traffic problems or brain cramps or weather to hamper progress.

So I would have arrived at Grenada at 3pm, as the northern batch of severe cells reached the interstate. There is a potential delay.

By 4pm cells were north and east of Jackson, with tornadoes reported just before 4pm near Leesburg and Forkville. The latter town happens to be in the Bienville National Forest (established in 1934).
I drive pretty fast if conditions permit but would likely have had to core plunge at least once, heading into a heavily-treed area. Usually the correct decision is just go, since I'll never see anything from my living room. But in retrospect this looks like a long shot on paper. I needed a closer warm front.
