An overnight flow of near-surface moisture off Lake Erie is resulting in another morning of dense fog, this time mainly east of US-127, with patchy/shallow fog possible to the west. The REFS has been handing fog probabilities fairly well the past few nights. Fog potential Sunday night is lower given cloudier skies.
