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

An EF1 tornado started just to the west of the intersection of County Road 636, causing minor roof damage to a home. The tornado continued east across County Road 602, County Road 616, County Road 627, and County Road 628, snapping and uprooting numerous trees, downing powerlines, damaging fences, and causing minor roof damage. Continuing east along Highway 2, the tornado caused minor damage to the roofs of several homes. The tornado then intensified, causing the most extensive damage at a church, removing part of the roof and blowing out a few windows. The tornado turned north and moved into the neighborhood along County Road 630, damaging several homes, before lifting. Peak winds were estimated at 100 mph.

The wider storm

A negatively tilted upper-level trough began to deepen as it moved from the northern Rockies into the Middle Mississippi Valley on Sunday afternoon, driving a potent cold front eastward. Mid-level heights also began to fall Sunday afternoon as impressive kinematics overspread the region. Moderately steep mid-level lapse rates greater than 7 C/km, along with SBCAPE values of 750-1200 J/kg and storm relative helicity values upwards of 300 m2/s2 developed ahead of the cold front. An impressive line of storms formed along and ahead of the cold front, producing a half dozen weak tornadoes, 75+ mph wind gusts, and large hail across the Mid-South.

Began near Kossuth (34.8912, -88.6302).
