Areas affected...parts of southern Wisconsin and northwestern
Illinois

Concerning...Severe Thunderstorm Watch 601...

Valid 060438Z - 060515Z

The severe weather threat for Severe Thunderstorm Watch 601
continues.

SUMMARY...Local severe risk may continue for another 1 to 2 hours
across southwestern Wisconsin and far northwestern Illinois. WW 601
will likely be extended in time, beyond its scheduled 06/05Z
expiration, to cover this ongoing threat.

DISCUSSION...Latest radar loop shows a cluster of strong/severe
storms moving east-southeastward out across southwestern Wisconsin,
out of WW 600 and into WW 601. Low-level moisture/instability
diminishes with eastward extent across southern Wisconsin, where an
easterly low-level lake fetch is indicated. However, ample
instability -- particularly across Grant and Iowa Counties in
Wisconsin and areas directly south in northwestern Illinois --
remains, which should allow this cluster of storms to persist awhile
longer. With some accompanying severe risk -- mainly in the form of
damaging wind -- to affect these counties, WW 601 will likely be
extended in time to cover this potential.
