What EF1 means. On the Enhanced Fujita scale, EF1 is moderate damage: roofs badly stripped, mobile homes pushed off foundations or overturned, windows broken, consistent with estimated gusts of 86–110 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

This tornado crossed U.S. Highway 41 about four miles southeast of Hopkinsville. Several trees were snapped along the path. One barn received some partial damage to its roof. Peak winds were estimated near 95 mph.

The wider storm

An unseasonably strong storm system impacted the region January 10-11. Heavy rainfall, flooding, scattered damaging winds, tornadoes, and gusty non-thunderstorm winds impacted western Kentucky during this time. The bulk of the event occurred overnight and into the morning hours on the 11th. Rainfall totals ranged from 2 to 5 inches, which resulted in pockets of flash flooding across the region, as well as minor flooding of the Green River. Strong to severe convection over the Ozark Mountains moved east into an environment of very strong wind shear over southeast Missouri, with 850 mb winds near 60 knots. The convection maintained intensity after it crossed the Mississippi River during the early morning hours. Tremendous wind shear (winds of 50 knots down to 1500 feet above ground) and strong forcing associated with a potent 500 mb shortwave compensated for weak instability. Some of the strong winds aloft reached the surface in the form of gradient wind gusts from 40 to around 50 mph. A weak surface low formed along a cold front over southwest Arkansas, then deepened as it tracked northeast across the Missouri Bootheel and into the lower Ohio Valley on the morning of the 11th.

Began near Casky (36.8143, -87.4434).
