Waves are provided as a range of significant wave heights, which is the average of the highest 1/3 of the wave, along with the average height of the highest 10% of the waves which will occasionally be encountered. .SYNOPSIS... High pressure around 30.0 inches over Lake Erie will gradually push into the Saint Lawrence River Valley through Monday, resulting in primarily light southerly winds across the open waters. Some dense fog may linger into this afternoon near the western shore of the lake. Showers and thunderstorms are possible at times tonight into Monday morning. A cold front will approach the open waters Monday night, resulting in a wind shift out of the west by sunrise Tuesday morning. Later Tuesday into Wednesday, there is a potential for stronger winds over the southern portion of the lake, depending on the eventual track of the remains of Tropical Storm Beryl, which may track across central and north central Indiana. This potential will be updated in later forecasts.
