The Latest Northeast Wisconsin Forecast from Storm Team 5…. Clouds have cleared up north today, but Green Bay and along the lakeshore pesky clouds have remained. Where the sun has been shining is where the warmest temperatures have been today but here in Green Bay temperatures have held at 32 degrees. If the stubborn clouds don’t clear by sunset, they will remain overnight. Areas that are clear overnight will see some patchy dense fog develop with relatively calm winds expected overnight. A few slippery spots on driveways or parking lots are possible as temperatures fall below freezing tonight, so freezing fog is possible.
