Actually, that was "replacement weathercaster 'Tom' " giving the forecast, a mere 12 hours or so after the "Golden Fleece," or whatever they're calling it today. The station later admitted it was their floor director playing the part of weather guy. (Hey, isn't that the former Dex phone book spokesman?)
But astute viewers could have easily picked out the forecast was a fake in the first few seconds. I mean, we all know Green Bay never gets below -180 in the winter. Don't believe me? Just Google it.
(Touche, Green Bay!)
