The radar

The La Crosse radar (KARX), 119 km from the middle of the area, began a volume at 22:18 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this tornado warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

What forecasters said that day

The local office's own words before this tornado warning went out, 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 this tornado warning went out at Apr 17, 1:34 PM CDT, 3 hours 40 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.

.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

.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.
