EF1 tornado, Kalinke to Doering, Wisconsin, April 17, 2026
From Kalinke to Doering, this EF1 tornado ran 4.3 miles across Marathon and Lincoln counties on April 17, 2026, touching down at 4:44 PM CDT and reaching 100 yards wide. It killed nobody.
Preliminary. This is NWS GRB's damage survey, filed in the Damage Assessment Toolkit as Glandon 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
A tornado developed about 3 miles northwest of Glandon, at the end of Pine Haven Road near County Road J, about 4:44 pm in Marathon County. The tornado produced significant damage to a barn by collapsing the entire top floor of half the barn, pushed a silo off its foundation, and damaged a metal outbuilding by tearing off most of the roof and some exterior walls. The tornado moved north-northeast, crossing the Lincoln County line around 4:46 pm. The tornado then crossed County Road X and Highway 64, downing trees and producing significant damage to garages and outbuildings by tearing off most of the roof of a garage. The tornado dissipated 5 miles south of Doering at the end of Elm Ridge Road in Lincoln County around 4:55 pm.

What the Weather Service recorded
A severe weather outbreak unfolded across central and north-central Wisconsin during the afternoon and early evening of Friday (4/17). The event was triggered by a surface low-pressure system and cold front across the upper Midwest. ||NWS storm surveys confirmed 2 tornadoes that resulted in structural damage. A tornado formed 3 miles northwest of Glandon around 4:44 PM CDT and tracked into southeast Lincoln County producing EF-1 damage before dissipating around 4:55 PM CDT. Another tornado formed 3 miles west-southwest of Ringle in Marathon County around 4:46 PM CDT and dissipated around 5:03 PM CDT 5 miles southwest of Hogarty. This tornado produced EF-3 damage and destroyed 13 homes, produced major damage to 25 homes, with 101 homes reporting minor damage or affected by the tornado. An estimated $8.2 million worth of damage was reported from the tornado. ||Beyond the tornadic threat, the storms produced isolated large hail up to half dollar size and damaging winds. Heavy rainfall was another impact, with localized totals ranging from 1 to 4 inches. These torrential downpours caused flash flooding, particularly in Marshfield where 2.65 inches of rain fell and multiple vehicles were reported stranded in deep water.

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 19:53 UTC.
SPC's Day 1 convective outlook as it stood when the tornado began, read at the touchdown point. The same archive is on the radar archive.
What forecasters said that day
The local office's own words before the tornado touched down, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Green Bay, WI wrote its last area forecast discussion before the tornado touched down at Apr 17, 1:34 PM CDT, 3 hours 10 minutes earlier. Its key messages:
- -Severe storms with a risk of tornadoes (possibly strong), large hail and damaging winds are increasingly likely from 3 pm to 8 pm today, with the highest risk across central Wisconsin. -Thunderstorms this afternoon and evening will produce locally heavy rainfall. If this occurs over the flood sensitive areas of central and east central WI additional significant flooding may occur. -Minor to major flooding will continue into next week with the greatest impacts expected on the Menominee and Wolf Rivers where major or record breaking flooding has been observed. -No significant precipitation is expected from Saturday through Thursday, but widespread showers and storms may return next Thursday night into Friday.

Area Forecast Discussion National Weather Service Green Bay WI 134 PM CDT Fri Apr 17 2026 Forecast discussion for routine afternoon forecast issuance .KEY MESSAGES... -Severe storms with a risk of tornadoes (possibly strong), large hail and damaging winds are increasingly likely from 3 pm to 8 pm today, with the highest risk across central Wisconsin. -Thunderstorms this afternoon and evening will produce locally heavy rainfall. If this occurs over the flood sensitive areas of central and east central WI additional significant flooding may occur. -Minor to major flooding will continue into next week with the greatest impacts expected on the Menominee and Wolf Rivers where major or record breaking flooding has been observed. -No significant precipitation is expected from Saturday through Thursday, but widespread showers and storms may return next Thursday night into Friday. && .DISCUSSION... Issued at 125 PM CDT Fri Apr 17 2026 Severe Thunderstorm and Flood Potential This Afternoon/Evening... Confidence is increasing in a significant, but fairly brief severe weather event. A narrow axis of SBCAPE (1500-2500 j/kg) was already developing ahead of a strong cold front over SE MN, NE IA and SW WI. This was coincident with 0-1km SRH of 200-250. Radar showed pre-frontal convection occurring in far SW WI and NE IA, with additional storms developing along the cold front in eastern MN. CAMs show intense convection, including supercells and line segments moving through the forecast area between 3 pm and 8 pm. Given the degree of shear, an all-hazard event, including tornadoes, is expected, with the tornado threat lessening for any storms nearing the lakeshore, where less instability will be present. A Tornado Watch has been issued along and south of Hwy 29 (away from Lake Michigan) through 8 pm. A lingering Severe Thunderstorm Watch is also still in effect for far NC WI until 5 pm. This will be a fairly short-lived event, as instability drops off rapidly after sunset. An additional band of light to moderate showers will accompany the cold front later this evening and overnight. Expect most locations to see between 0.50 and 1 inch of precipitation with event, which will exacerbate ongoing flooding. A Flood Watch remains in effect for all but the far northwest part of the CWA. The cold frontal passage will bring a period of cooler weather through the weekend into early next week. The best chance of precipitation during this period will be 20-40 percent chance of snow/rain showers over C/EC WI on Sunday, in association with a short-wave trough and cold frontal passage. Mainly dry and warmer weather is expected for the middle of next week, with high temperatures reaching into the 60s and 70s. An approaching cold front brings another potentially significant round of showers and storms Thursday night into Friday. && .AVIATION...for 12Z TAF Issuance Issued at 628 AM CDT Fri Apr 17 2026 Fog and very low stratus continues near Lake Michigan due to moist SSE flow off the cold waters. This will likely improve as low- level winds become southwest this evening, then northwest behind a cold front overnight. Thunderstorms storms were develop ahead of a cold front, and are likely to become severe as they move through the forecast area between 20z/Fri-01z/Sat. Flight conditions will quickly lower to MVFR/IFR during the storms, with MVFR and local IFR ceilings lingering into the late evening and overnight. A second band of showers will accompany the passage of the cold front tonight. Expect flight conditions to improve to VFR late tonight into early Saturday. South southeast surface winds will gust to 25 to 35 kts this afternoon, then become NW 15 to 25 kts after the cold front moves through this evening and overnight. Ahead of the front, periods of LLWS will continue. && .HYDROLOGY... Issued at 125 PM CDT Fri Apr 17 2026 A Flood Watch is in effect through tonight, due to an expected half inch to an inch of rain from thunderstorms this afternoon and evening. Locally higher amounts are possible. Flooding continues along multiple rivers due to the combination of snow melt and recent heavy rainfall, including major flooding along the Wolf and Menominee Rivers. If you live near a river or stream, continue to monitor the latest hydro forecasts and Flood Warnings from the National Weather Service in Green Bay. && .GRB WATCHES/WARNINGS/ADVISORIES... Flood Watch through Saturday morning for WIZ011>013-019>022-030- 031-035>040-045-048>050-073-074. && DISCUSSION.....Kieckbusch AVIATION.......GK HYDROLOGY......Kieckbusch

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.
