Areas affected...Western/northern Wisconsin to Upper Michigan

Concerning...Severe Thunderstorm Watch 427...

Valid 171245Z - 171415Z

The severe weather threat for Severe Thunderstorm Watch 427
continues.

SUMMARY...At least isolated severe storms, capable of damaging winds
and possibly some hail, will continue to focus across west-central
Wisconsin through mid-morning, and may spread into additional parts
of central/northern Wisconsin, where an additional Watch could be
needed. Severe Thunderstorm Watch 427 continues until 15z.

DISCUSSION...A relatively small-scale quasi-linear cluster remains
strong/severe this morning as it approaches the I-94 corridor of
west-central Wisconsin including the Eau Claire area. This cluster
will likely continue northeastward, favoring the instability
gradient that extends across southwest/west-central Wisconsin toward
northeast Wisconsin and the eastern Upper Peninsula of Michigan.
This cluster has a general history of severe-caliber wind gusts in
the predawn hours, including a measured 53 kt gust at Rochester
Minnesota. An additional Watch could be warranted for portions of
central/northern Wisconsin pending short-term convective trends.
