The tornado touched down about 3 miles SSE of Annapolis and progressed northeast for 2 miles. During its lifespan it produced primarily tree damage, along with some minor roof damage to a garage. The tornado reached peak intensity near E 1700th Ave and N 825th St where large trees were uprooted. The remainder of the damage was minor tree damage.

Written by NWS ILX in the NWS Damage Assessment Toolkit. A survey is revised as better evidence arrives.

34 damage points were recorded along this path by NWS ILX, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF1. The highest wind the damage implies is 100 mph.

• Trees snapped in the middle with branches broken half a mile to the north
• Tree uprooted and nearly missed propane tank
• Tree branches shredded and snapped off to the north of the point
• Shredding of tree line to the east over 1/2 mile, in line with tree line damage to west

Survey points are preliminary and are the raw material the published rating was built from. Source: NWS Damage Assessment Toolkit.

A remnant Mesoscale Convective Vortex (MCV) interacted with a sheared and unstable environment to produce numerous supercells in southeast Illinois on June 21st. 13 tornadoes were documented, the strongest being two EF-2 tornadoes near Newton. Storms training over the same areas led to widespread heavy rainfall and several occurrences of flash flooding.

The tornado began 3 miles southwest of Annapolis and tracked east-northeast toward N 825th St. It continued northeast from there, ending about 4 miles east of Annapolis north of E 2000th Ave. Damage along the path was mostly to trees and electrical transmission lines.

From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.

18 minutes of warning. NWS ILX issued a tornado warning for this county at 21:23 UTC, 18 minutes before the tornado touched down, in force until 22:06 UTC.

The county was under a tornado watch, issued at 18:28 UTC and running to 02:54 UTC.

Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The Storm Prediction Center had this point in a Slight Risk, with a 0.05 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 19:57 UTC.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. A survey can be revised, so the rating, the path and the casualties can all still change.
