Areas affected...2Southern Wisconsin into central Lower Michigan

Concerning...Severe Thunderstorm Watch 106...107...

Valid 140443Z - 140615Z

The severe weather threat for Severe Thunderstorm Watch 106, 107
continues.

SUMMARY...Occasional damaging gusts of 60-70 mph and isolated large
hail near 1 inch in diameter will be possible along the conglomerate
outflow through 06z.

DISCUSSION...Thunderstorms have grown upscale into an extensive QLCS
with a conglomerate cold pool extending from northeast IA across
southern WI and into central Lower MI. The predominately east-west
orientation of the QLCS in westerly flow aloft suggests that most of
the stronger updrafts will remain slightly to the cool side of the southeast-moving outflow. A few smaller scale bowing segments will
be possible, especially with cell mergers into the line, which is
more probable across central Lower MI. Occasional damaging outflow
gusts of 60-70 mph and hail near 1 inch in diameter will be the main
threats through at least 06z.
