EF1 tornado, Chestervale to Newburg, Illinois, June 10, 2026
From Chestervale to Newburg, this EF1 tornado ran 19.8 miles across Logan and Macon counties on June 10, 2026, touching down at 11:19 PM CDT and reaching 170 yards wide. It killed nobody.
Preliminary. This is NWS ILX's damage survey, filed in the Damage Assessment Toolkit as Mount Pulaski-Forsyth Tornado. The rating, the path and the casualties are the survey's and can change while it is revised. The Storm Prediction Center compiles the official record of 2026 from these surveys and publishes it in the spring of 2027; this page moves to that tornado's permanent address when it does.
The rating scale
Tracks are drawn in the color of the rating. The Enhanced Fujita scale rates the damage rather than measuring the wind: the speeds are what that damage is taken to imply.
EF065 to 85 mph
Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.
EF186 to 110 mphthis tornado
Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.
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.
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.
EF4166 to 200 mph
Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.
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.
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.

What the survey found
The tornado touched down about 3 miles northwest of Mount Pulaski
where it did some minor tree damage. The tornado intensified as it
progressed east along 900 St, where it did extensive tree damage for
about a half mile, damaging numerous trees. The tornado angled
southeast and crossed Hwy 54 producing more tree damage. The tornado
produced mainly tree damage for the remainder of its time on the
ground, dissipating about 3 miles north of Forsyth.

The damage survey
56 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 88 mph.
- Large branches ripped from trees and blown across road
- Branches snapped looking east from dead end drive
- Several trees with damage along the tree line
- Numerous trees damaged in this line of woods

What the Weather Service recorded
A line of thunderstorms developed ahead of an approaching cold front during the evening of June 10th. Scattered wind damage was observed along and north of the I-72 corridor, with the most concentrated damage focusing across portions of Menard, Logan, Sangamon, and Macon counties where the cells interacted with an existing outflow boundary from earlier storms. Six tornadoes touched down within this corridor, including an EF-1 tornado that tracked across Abraham Lincoln Capital Airport and the north side of Springfield.
A tornado touched down north of the junction of 900th Street and 878th Street about 3 miles northwest of Mount Pulaski at 11:19pm CDT. The tornado caused extensive tree damage as it tracked eastward along 900th Street before curving to the southeast and causing additional tree damage as it crossed IL-54. It then tracked into northwestern Macon County along 2400th Avenue between West Hampshire Road and West School Road at 11:32pm CDT.
This tornado crossed from Logan County into Macon County along 2400th Avenue between West Hampshire Road and West School Road at 11:32pm CDT. It continued southeastward, causing mostly minor tree damage before dissipating just west of the intersection of US-51 and West Wise Road about 3 miles north of Forsyth at 11:42pm CDT.
A tornado touched down along East Hampshire Road about 2 miles west-northwest of Argenta at 11:50pm CDT. It tracked east-southeastward damaging an outbuilding and trees before passing through Argenta and snapping numerous trees. The tornado then produced additional tree damage before crossing into Piatt County near the intersection of Newburg Road and County Line Road at 11:55pm CDT.
From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.

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 forecast that day
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 01:19 UTC.

What this means
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.
