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...

winds will veer westerly today as high pressure of 29.8 inches
crosses the upper great lakes. southerly winds will become 
established tonight ahead of a new area of 29.6 inch low pressure 
forming in the northern great plains. the low will cross lake 
michigan tuesday morning, resulting in a west-northwest wind shift
by the afternoon hours.

increasing northeast winds by friday morning as low pressure
around 29.5 inches crosses the southern tip of lake michigan. one
more low is expected to deepen over lower michigan on saturday.
the strength on the low is uncertain, but gusty northwest winds 
are possible on the back side saturday afternoon and night.
