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

.synopsis...

high pressure of 29.9 inches builds into the upper great lakes

remains in effect for the northern 2/3 of the lake until midday

forecast, particularly late monday through monday night.
additional chances later in the week.
