A strong line of thunderstorms made it’s way through Western Wisconsin to start Sunday morning. Frequent lightning, small hail, and wind gusts over 40 mph were associated with the line of storms that had a history of producing gusty winds and hail overnight.
Models continue to disagree on the next initial development of storms for this afternoon. While heat and humidity will be factors in storm severity, the timing and strength of the frontal boundary moving through is causing plenty of uncertainty.
There is still a slight risk, ‘level 2’, for severe weather across most of the Chippewa Valley. Torrential rain, damaging winds and small hail are the main threats for the next round of storms.
Once the first line of storms clears we will get quickly rising temperatures that could reach 90 degrees. With dew points climbing into the 70’s today, it will be very uncomfortable and those sensitive to heat should take caution. Especially with heat indices potentially breaking 100 degrees this afternoon.
