The episode as NWS DLH wrote it up.

These storms were elevated in nature due to the warm front with large hail and heavy downpours being the primary threats. However, some of the stronger winds were able to mix down to the surface across the Apostle Islands with a measured gust to 59 mph being reported at Devils Island.
