Areas affected...Northeast Wisconsin...southern U.P. of Michigan

Concerning...Tornado Watch 185...

Valid 290335Z - 290500Z

The severe weather threat for Tornado Watch 185 continues.

SUMMARY...Strong-severe convection will spread across northeast
Wisconsin into the southern portions of the U.P. of Michigan. New
watch is not currently anticipated.

DISCUSSION...A long-lived elongated MCS is progressing
east-northeast across WI. Much of this activity has struggled to
generate more than isolated damaging winds and hail, though one
notable supercell is tracking along this corridor over
Langlade/Menominee County. Latest VWP data from GRB exhibits intense
0-3km SRH as a strong LLJ is focused across IA into this portion of
the upper Great Lakes. While some tornado risk continues, especially
with embedded supercells, the primary concern going forward appears
to be wind/hail. Latest radar data supports a strengthening
low-level warm advection regime as numerous elevated storms extend
across the southern U.P. of MI. At this time a new watch is not
anticipated downstream across the U.P., but some risk for hail may
be noted, especially over Menominee County MI.

PUBLIC SEVERE WEATHER OUTLOOK  
NWS STORM PREDICTION CENTER NORMAN OK
0852 PM CDT MON APR 28 2025

...Severe thunderstorms expected over parts of the Upper Midwest
this evening and overnight...

* LOCATIONS...
  Wisconsin
  Northern Iowa
  Far Southeast Minnesota

* HAZARDS...
  Several tornadoes, a few intense
  Scattered large hail, some baseball size
  Scattered damaging winds

* SUMMARY...
  Multiple corridors of severe thunderstorms will continue this
  evening from the Upper Midwest into the central and southern
  Plains. Tornadoes, large hail, and severe gusts all remain
  possible, including some potential for strong tornadoes.

Preparedness actions...

Tornadoes at night can be particularly dangerous because they 
are usually fast-moving and difficult to see. Stay tuned to
NOAA Weather Radio, weather.gov, or other media for watches and
warnings. A tornado watch means that conditions are favorable
for tornadoes to form during the next several hours. If a tornado
warning is issued for your area, move to a place of safety,
ideally in a basement or interior room on the lowest floor of a
sturdy building.
