What happened

The episode as NWS MKX wrote it up.

Dense fog developed overnight on June 2nd and lowered visibilities to 1/8 to 1/4 mile. A few early-morning airplane flights were delayed at the Sheboygan County airport. A light southeast wind off Lake Michigan, mostly clear skies, and left-over evaporated moisture from rain during the daytime on June 2nd set the stage for dense fog.

What forecasters said that day

The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Milwaukee, WI wrote its last area forecast discussion before the first event at Jun 2, 2:06 PM CST, 6 hours 54 minutes earlier.
