The path drawn at its surveyed width of 80 yards (0.05 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

What EF0 means. On the Enhanced Fujita scale, EF0 is light damage: shingles and siding peeled, gutters torn, branches broken, consistent with estimated gusts of 65–85 mph. The rating comes from a survey of the worst damage after the storm, not from a wind measurement, so it says as much about what the tornado hit as about how strong it was.

What the National Weather Service wrote

A brief tornado passed through Golden, with damage first beginning along Patterson Street in the form of small tree limbs and a power line downed. The most significant damage was along Front Street, where a towing service building was knocked down, a shed was flipped, and the framing of a house under construction collapsed. Also, along Line Road, a shed was destroyed and power lines were downed. Numerous trees were uprooted from Line Road to Moore Road as well. Additional trees were uprooted just north of Bear Creek Road until the tornado dissipated on the banks of Bear Creek. Peak winds were estimated at 85 mph.

The wider storm

A regional tornado outbreak occurred during the late afternoon of Friday, March 31, 2023, and continued into the early morning hours of Saturday, April 1, 2023. This outbreak covered portions of the Ohio Valley, and the Middle and Lower Mississippi Valleys, including a good portion of the Mid-South and stretching into the Tennessee Valley. On Friday, March 31, a surface low was located near La Crosse, WI, with a cold front stretching south into central/southwest Missouri, western Arkansas, and into eastern Texas. Surface temperatures were mainly in the 70s to approaching 80 degrees with surface dewpoints in the lower to middle 60s, yielding Surface-Based CAPE (SBCAPE) values between 1500-2000 J/kg by Friday evening. Favorable upper-level divergence produced by the right entrance region of a 140-kt jet streak at 300 mb provided ample lift to produce strong to severe thunderstorms across the region. Directional and speed shear were impressive with 70-80 knots of Effective Bulk Shear present and 0-1 km Storm Relative Helicity values between 500-600 m2/s2, all more than enough for organized thunderstorms across the area. Discrete supercells started to develop across the Lower Mississippi Valley during the afternoon hours on March 31, 2023, eventually tracking into the Mid-South by late afternoon. The first supercell that developed in the Mid-South produced an EF-3 that caused major damage in Wynne, Arkansas. Tornadic supercells continued to produce significant tornado damage across the Mid-South into the early morning hours of April 1, 2023. The hardest hit areas besides Wynne, Arkansas included Covington, Tennessee, and McNairy County, Tennessee. Overall, 14 tornadoes occurred across the Mid-South along with several reports of wind damage and measured damaging wind speeds. Eighteen people in the Mid-South lost their lives in this outbreak.

Began near Golden (34.4851, -88.1953).
