EF1 tornado, Mitchellsville to Eagle, Illinois, May 16, 2025

1. EF065 to 85 mph

   Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.

2. EF186 to 110 mphthis tornado

   Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.

3. EF2111 to 135 mph

   Considerable damage. Roofs torn off well-built houses, frame homes shifted on their foundations, mobile homes destroyed, large trees snapped or uprooted, cars lifted off the ground.

4. EF3136 to 165 mph

   Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.

5. EF4166 to 200 mph

   Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.

6. EF5over 200 mph

   Incredible damage. Strong frame houses swept off their foundations, car-sized missiles thrown more than 100 meters, steel-reinforced concrete badly damaged, high-rise buildings deformed.

7. Unrated

   The survey recorded a tornado but could not put a number on it, most often because it crossed open country and damaged nothing a rating can be read from.

11 damage points were recorded along this path by NWS PAH, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF2. The highest wind the damage implies is 115 mph.

• Dozens of trees snapped in a path.

A 500mb shortwave trough moved across the Upper Midwest with height falls across the Quad State during the afternoon and evening of the 16th. The exit region of a strong (125kt) upper level jet was positioned across the area as well. Low-level winds strengthened during the afternoon to 50kts at 850mb. Following the early AM convection, ample sunshine allowed for a very unstable airmass to develop with CAPE of 3000-4000J/kg with deep layer shear of 65-70kts. Late afternoon, STP peaked at 9 near the Wabash/Ohio River confluence with effective SRH of 300-400m2/s2. Mid-level lapse rates peaked at 8-8.5C/km for much of the Quad State with significant hail parameter of 3-5 mid-afternoon and DCAPE peaking at 1200-1500J/kg. Initial storm formation was discrete with very large hail and tornadoes, with storms becoming more linear later in the evening with the approach of a cold front.||Damage reports were widespread near and south of IL-13 in Southern Illinois. An especially powerful supercell produced a violent tornado south of Marion with peak winds estimated at 190mph, the strongest in the Quad State region since the December 10, 2021 Western Kentucky tornado. The worst of the damage was between Andrew Rd and Wards Mill Rd with the EF-4 damage point a home swept off its foundation on Kyler Ct. This supercell would continue on to produce two more tornadoes (in Southeastern Saline and Southern Gallatin Counties) before crossing into Northwestern Kentucky. Large hail was commonplace with the afternoon supercells, with the largest reports being multiple baseball size hail reports in Pulaski County.

An EF-1 tornado damaged trees in a 6.78 mile long path across southeast Saline County, Illinois. No structural damage was reported. Estimated peak winds were 88 mph. This was the second tornado to form from the supercell that produced an EF-4 in Williamson County, IL.

An EF-2 tornado (peak of EF-1 in Saline County) began in far southeast Saline County and then tracked eastward, quickly crossing into southern Gallatin County at Forest Road. Tree damage, including an uprooted tree, was observed in Saline County. Estimated peak winds with the Saline County portion of the tornado were 94mph. This was the third tornado to be produced by the supercell that had developed the Williamson County EF-4 tornado earlier in the evening.

23 minutes of warning. NWS PAH issued a tornado warning for this county at 23:25 UTC, 23 minutes before the tornado touched down, in force until 00:00 UTC.

The county was under a tornado watch, issued at 20:01 UTC and running to 00:49 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 Moderate Risk, with a 0.15 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 19:31 UTC.

26 more were confirmed in the United States that day.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
