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... Easterly winds will continue across the lake overnight as low pressure of 29.2 inches continues north towards the Great Lakes region. Winds on Tuesday will remain easterly, but will begin to accelerate throughout the day as the low approaches, leading to the potential for gales across the lake by Tuesday evening. As such, a Gale Watch is in effect from Tuesday evening through Wednesday evening. Winds across much of the lake will decelerate and shift southerly to southwesterly Wednesday as the low moves north across central Wisconsin, but easterly gales are still possible over the far northern portion through Wednesday evening before also turning westerly and decelerating. Westerly winds will then continue Thursday morning before becoming southwesterly by Thursday afternoon for the entire lake as the low departs the area.
