Areas affected...Southeastern Minnesota...northern Iowa...and far
western Wisconsin

Concerning...Severe Thunderstorm Watch 469...471...

Valid 110235Z - 110330Z

The severe weather threat for Severe Thunderstorm Watch 469, 471
continues.

SUMMARY...Severe threat continues within WW471.

DISCUSSION...A line of thunderstorms moving across southeastern
Minnesota has been producing severe hail, generally 1-1.75 inches,
over the last hour. This broken line of storms further intensified
as it absorbed a northward moving outflow. As this tracks southward
further into WW471, potential for more severe hail is likely with
secondary potential for scattered damaging winds. Given the
uncertainty of the downstream environment, with overturn and
mid-level CIN from previous storms, it is not clear how long this
line will maintain severe characteristics extending into WW469. The
severe threat will persist across southern Minnesota into northern
Iowa over to far western Wisconsin over the next 1-2 hours.
