The radar

The Milwaukee radar (KMKX), 107 km from the middle of the area, began a volume at 23:33 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 Milwaukee, WI wrote its last area forecast discussion before this tornado warning went out at Apr 15, 3:43 PM CDT, 2 hours 46 minutes earlier. Its key messages:

  • A Slight Risk (2 out of 5) for severe weather exists this afternoon. Primary risks will be hail and gusty winds, though the strength of the storms is not expected to be comparable to yesterday. Southwest Wisconsin and areas along the WI/IL border have the best chances to see a strong to severe storm.
  • Heavy rainfall from more thunderstorms this afternoon and evening could lead to additional periods of flooding into Thursday morning. A Flood Watch has been issued for all of southern Wisconsin.
  • Additional windows for heavy rainfall, flooding, and severe thunderstorms Friday into Saturday.

.KEY MESSAGES...

- A Slight Risk (2 out of 5) for severe weather exists this
  afternoon. Primary risks will be hail and gusty winds, though
  the strength of the storms is not expected to be comparable to
  yesterday. Southwest Wisconsin and areas along the WI/IL
  border have the best chances to see a strong to severe storm.

- Heavy rainfall from more thunderstorms this afternoon and
  evening could lead to additional periods of flooding into
  Thursday morning. A Flood Watch has been issued for all of
  southern Wisconsin.

- Additional windows for heavy rainfall, flooding, and severe
  thunderstorms Friday into Saturday.

&&

.SHORT TERM...
Issued 335 PM CDT Wed Apr 15 2026

Tonight through Thursday night:

More thunderstorms are possible this evening as return flow is
expected to advect appreciable SBCAPE from 1000 to 1500 J/kg
into southwest WI and up to the WI/IL border. Storms tonight may
be a bit weaker than yesterday given skinnier CAPE profiles, but
low level instability, effective shear around 40 knots, and
some curvature in the hodographs will support another round of
gusty winds and hail. An isolated tornado can't be ruled out
along the WI/IL border given the low level turning in the
hodographs and low level instability, provided a low-topped
supercell forms in the environment this afternoon.

Storms will quickly grow upscale after sunset, leading to more
widespread rain. Training thunderstorms may lead to more flash
flooding tonight given the wealth of rain we've had this week. A
Flood Watch is in effect from 4pm this afternoon to 7am Thursday
for the expected rainfall tonight. A widespread 1 to 2 inches
may fall, with locally higher amounts possible where any
thunderstorms track.

Storms largely move offshore tonight around midnight, with more
scattered rain possible between midnight and 7am. Rain should
then largely taper off Thursday morning, with dry conditions
Thursday afternoon. A weak surface ridge will then move overhead
Thursday night.

.LONG TERM...
Issued 335 PM CDT Wed Apr 15 2026

Friday through Wednesday:

A strong cold front is expected to move through Friday afternoon
and evening and is expected to lead to another round of severe
weather. At this time the GFS depicts strong warm ahead of the
front which will allow dew points in the 60s to return
northward. Model soundings depict 40 knots of effective shear
amid moderate instability of 2000 J/kg, with low level turning
in the hodographs. This would support all modes of severe
weather again for the area. At this time the SPC has included
southwest and south central Wisconsin in an enhanced risk for
severe weather.

The cold front will then come crashing through Friday night into
Saturday, and temperatures will dip into upper 40s to low 50s
for the weekend. Saturday is expected to be cool and breezy,
with breaks in the clouds late in the day. Sunday will feature
similar conditions but will be a tad bit sunnier as a high
pressure center moves overhead.

Warmth is then expected to return next week Tuesday as a ridge
builds over the central United States. The middle of next week
then looks active again as a low pressure moves off of the lee
of the Rockies.

CMiller

.AVIATION...
Issued 307 PM CDT Wed Apr 15 2026

MVFR and VFR conditions generally exist over most of the area
while IFR is hanging on over east central WI. Thunderstorms are
expected to move in late this afternoon and evening into the
west and grow upscale, leading to widespread rain over the area.
Before storms grow upscale, hail and gusty winds will be
possible with any strong storms over southwest Wisconsin and the
WI/IL border. Winds will generally be light and variable
overnight as a front sinks south over the region, becoming
northerly by daybreak on Thursday. More fog is possible tonight
mainly over southeast, east central and central WI, with some
dense fog possible.

CMiller

&&

.MARINE...
Issued 251 PM CDT Wed Apr 15 2026

A stationary front will remain parked over the middle third of
the lake this afternoon, slowly sinking south to the southern
end of the lake by noon Thursday. A Marine Dense Fog Advisory
continues until Thursday morning while this front lingers.
Winds will remain southerly south of the front and modestly
breezy, while winds north of the front will remain light and
variable to northerly during this time. The front will then
clear the lake Thursday afternoon and northerly winds will
prevail over whole lake. Winds will become light and variable
briefly Thursday night as a weak ridge passes over the lake,
with winds then becoming southerly and breezy Friday ahead of
low pressure of 29.6 inches approaching from the west. Gusty
northwest winds then return following a cold front Friday night.

Additional thunderstorms are forecast over the southern
third of Lake Michigan this evening into tonight. A few storms
could be severe with large hail being the primary concern.
Additional storms are possible Friday into Saturday, with a few
stronger storms possible.
