The severe weather threat for Severe Thunderstorm Watch 400
SUMMARY...Although isolated instances of severe wind and/or hail may
continue for a couple more hours, a downstream watch is not
anticipated south of the remaining valid counties in Severe
Thunderstorm Watch 400.
DISCUSSION...Scattered strong/occasionally severe storms were in
progress across central and southern Wisconsin at 0425Z, with the
strongest storms currently south of the watch area northwest of
Milwaukee and just north of Madison. Latest objective analysis
reveals an environment supportive of a continued risk for isolated
strong/severe storms with moderate MUCAPE and 30-35 kts of effective
shear. Current radar trends suggest that the overall severe risk
will remain isolated and as a result a downstream watch is not
currently anticipated. Nevertheless, a couple stronger storms will
continue to pose a risk for large hail and damaging wind gusts for
at least the next 1-2 hours.
